Purpose: This study aimed to estimate the vernal keratoconjunctivitis prevalence, describe the profile of sensitization and determine the association between vernal keratoconjunctivitis disease and intestinal parasitic infestation in school children of Kinshasa during the scholar year from 2022 to 2023. Methods: An observational, cross-sectional study was performed from September 2022 to June 2023. The children with vernal keratoconjunctivitis were recruited by using the four-stage probability sampling technique. Children attending in the school children of Kinshasa with vernal keratoconjunctivitis were enrolled in the classroom and underwent a clinical examination and skin prick test for 11 allergens and stool examination direct with microscope in the Laboratory. Data were entered in Microsoft Sheets using SPSS version 20.0. The Chi-square test was used to compare the sex, age groups, home environment (grow trees and/or flowers around the yard), dampness in the house, keeping pets (cat and/or dog), number of people per household, number of people sharing a bedroom and intestinal parasitic infestation. The significant level was set to a value of p Results: A total of 28,800 students from four-stage probabilist sampling technique in school of Kinshasa were included, and 2100 students had symptoms according to the vernal keratoconjunctivitis-related symptom questionnaire. Children with vernal keratoconjunctivitis were enrolled and the mean age ± standard was 7.2 ± 3.7 years, with a prevalence of 7.2% and gender was three boys for one girl. All vernal keratoconjunctivitis children recruited in urban and rural part had 33.1% positive skin prick test (SPT) and 67.9% showed polysensitization. Children an urban part was more sensitized than rural respectively with Dermatophagoides pteronyssinus 28.1% vs 28.9%, p = 0.00001, Blomia tropicalis. 15.9% vs 14.9%, p = 0.00001 and cockroach 12% vs 13%, p = 0.00001 in both parts. Vernal keratoconjunctivitis children in rural part were more affected to the intestinal parasite than urban with Ascaris lumbricoides 14% vs 18.3%, p = 0.0006, followed by Ancylostoma duodenale 9.5% vs 12.5%, p = 0.003, Anguillule 7.9% vs 10.1%, p = 0.001, Oxyure 5.7% vs 8.2%, p = 0.0001 and Trichuris trichiura 2.6% vs 3.3%, p = 0.0009. Conclusion: This study outlines that the prevalence of vernal keratoconjunctivitis was 7.2% and 33.1% of children attending for vernal keratoconjunctivitis in school children had a positive skin prick test to at least one allergen, in particular for Dermatophagoides pteronyssinus, Blomia tropicalis and cockroach. The most common intestinal parasitic infestation was Ascaris lumbricoides, Ancylostoma duodenale, Anguillule and Trichuris trichiura.展开更多

This study was aimed to determine the frequency and patterns of URE across 4 gradients of residential densities（urban, exurban, suburban and rural）. This was a cross-sectional study of school children from 3 districts in Yogyakarta and 1 district near Yogyakarta, Indonesia. The information regarding age, sex, school and school grader were recorded. The Snellen＇s chart was used to measure the visual acuity and to perform the subjective refraction. The district was then divided into urban, suburban, exurban and rural area based on their location and population. In total, 410 school children were included in the analyses（urban=79, exurban=73, suburban=160 and rural=98 school children）. Urban school children revealed the worst visual acuity（P〈0.001） and it was significant when compared with exurban and rural. The proportion of URE among urban, suburban, exurban and rural area were 10.1%, 12.3%, 3.8%, and 1%, respectively, and it was significant when compared to the proportion of ametropia and corrected refractive error across residential densities（P=0.003）. The risk of URE development in urban, suburban, exurban, and rural were 2.218（95%CI： 0.914-5.385）, 3.019（95%CI： 1.266-7.197）, 0.502（95%CI： 0.195-1.293）, and 0.130（95%CI：0.017-0.972）, respectively. Urban school children showed the worst visual acuity. The school children in urban and suburban residential area had 2 and 3 times higher risk of developing the URE.展开更多

At the pre-school children, the stress of the disease makes children become less able to cope with separation. As a result, many children show anxious behavior though more vague than toddler age children. Various ways have been conducted by nurses to treat anxiety in children, but the most effective types of the intervention have not be found. Types of intervention that can be done are art therapy and play therapy. This study aims to compare the effects of art therapy and play therapy in reducing anxiety on children who experience hospitalization. A quasi-experimental research design with pre-post test two group design is used. The sample was 23 children pre-school age for art therapy group and 25 children for play therapy with sampling techniques performed purposive sampling. Intervention of art therapy and play therapy each performed for 3 days with duration about 30 minutes. Anxiety levels before and after the intervention were measured by using the facial affective scale. The results show that there is a difference in anxiety between before and after the action in the art therapy group (p = 0.00) and that there are differences in anxiety before and after the action in the play therapy group (0.00). But statistical tests using Man Whitney U indicate that there is no difference in anxiety levels in pre-school children who do art therapy and play therapy (p = 0.26). So, it is concluded that the art therapy and the play therapy can reduce the level of anxiety on pre-school school children that experience hospitalization. Based on these conclusions, it is recommended that the art therapy and the play therapy can be used by nurses and the choice of the intervention should be submitted to the child.展开更多

About 413 children aged 62^/1 - 82^/1 years from urban （236）, rural （80） and industrial areas （97） were studied. Blood lead was analyzed using the Atomic Absorption Spectrophotometer （GFAAS）. Cognitive development was measured by the ＇McCarthy Scales of Children＇s Abilities Test＇ （MSCA）. Significant differences found in the mean cognitive scores between the urban （94.40）, industrial （102.90） and suburban children （101.24） （p 〈 0.001）, with the blood lead between the urban （3.66 p.g/dL）, industrial （3.54 μg/dL） and suburban children （3.04μg/dL） （p = 0.022）. Significant inverse correlations between blood lead and cognitive scores found for all groups （p 〈 0.001）, urban （p 〈 0.001） and suburban children （p 〈 0.001）. Low blood lead significantly influenced the cognitive development for all children after adjusting for confounders （p _〈 0.001）. The urban children＇s cognitive scores were significantly influenced by blood lead levels and household income （p 〈 0.001）. However, for the suburban children, the cognitive score were significantly influenced by the blood lead levels, the mothers＇ education, number of siblings, sequence in the family and the household income （p 〈 0.001 ）. Blood lead below 10μg/dL influenced the cognitive development. Urban children had higher blood lead but suburban children with lower blood lead were also vulnerable to the effect of lead on their cognitive development.展开更多

Data for this analysis were from the 2010 Mongolia Global School-Based Health Survey （GSHS）. The GSHS administered a self-report questionnaire to a nationally representative sample （N = 5,328） of 7th-llth grade school children. Chi-square analyses and multivariate logistic regressions were performed to determine the prevalence and to predict the fruit and vegetable intake from associated factors. Only 7.0% of students met WHO＇s recommendation of eating fruits and vegetables S or more times per day. There was a significant association between gender and fruit and vegetable intake （P = .016）. There was a significant relationship between living condition and fruit and vegetable intake （P =.029）. Students who lived in apartment were more likely to have adequate fruit and vegetable intake than those who lived in ger in the khashaa. To be effective, educational interventions should be implemented as early as possible.展开更多

The inclusion criterion was >-6D of the spherical equivalent refraction. The object ophthalmic examinations were done, included non-cycloplegic objective refraction, visual acuity, intraocular pressure, fundus evaluation by ophthalmologists and nurses with professional training. Specially designed questionnaires were filled in and the data were statistically analyzed with SPSS10.0.Results: Of 11514 eyes, the detection rate was 81.4%(9376eyes) for myopia and 5.3%(615 eyes) for high myopia. High myopia was found in 2.6%.(300 eyes).of right eyes, 2.7%(315 eyes) in left eyes, and 2.4%(275 eyes) were in boys and 2.9%(340 eyes) in girls. Among 12 school grades, the detection rates of high myopia increased significantly with student age, with 0.9% in the 1stgrade of primary school and12.5% in the 3rd year of senior middle school. The average refractive error of spherical equivalent refraction was(-7.43±1.29) D with 95% confidence interval(-7.54,-7.33). No significant differences were found between the right and left eyes or both genders. The distribution of myopic severity was lowest(-6D).in primary school students younger than 12 years,was higher(-8D) in junior middle school students older than13 years, and highest(-13D) in senior middle school students.Conclusion: A continuous growth was evident in the severity of high myopia throughout 12 years of primary and middle school except for the first year of primary school, with growth occurring in two transitional stages between the senior primary and junior middle school years, and between the junior and senior middle school years. The distribution of high myopia was lowest, at-6D, in primary school, increased to-8D in junior middle school, and progressed to-10D in senior middle school, indicating a high risk of development of pathologic myopia during the students’ later lifespan. The adolescent period of 13 to 18 years of age in middle school is a critical period for the development of pathological myopia over-8D.展开更多

In this study, a cross-sectional study was conducted in two divisions in Nairobi province to determine the prevalence of and some risk factors associated with overweight and obesity among school children in Nairobi, Kenya. It involved 344 school children aged 9-14 years drawn from four randomly selected public and private primary schools. Weight and height were measured and body mass index was calculated. Nutrition status was determined using the World Health Organization age and gender specific BMI-for-age Z-scores (BAZ). The chi-square test was used to determine the relationship between overweight/obesity and selected socio-demographic characteristics. Complete anthropometric measurements were available for 321 children. Prevalence of combined overweight and obesity (BAZ > +1SD) was 19.0%, with prevalence being higher among girls (21.0%) than boys (16.9%) (p = 0.632). The prevalence among children in private schools was significantly higher (29.0%) than among those in public schools (11.5%) (p = 0.000). In addition, being a single child (p = 0.020), birth order (p = 0.017), mother’s occupation (p = 0.023) and type of residence (p = 0.028) were positively associated with overweight/obesity. The prevalence of overweight/obesity determined in this study is high and is a public health concern, with girls particularly at risk of becoming overweight.展开更多

Myopia is else known as short-sightedness and is considered as one of the most frequent causes of reduced vision especially in adolescents. Adolescence is one of the life periods when most cases are diagnosed with myopia. Purpose: The aim of this study was to identify myopia in pre-school and school children (3 - 9 years old in Prishtina), to determine the prevalence of myopia among other refractive anomalies in cases included in the study;compare the prevalence of myopia in this population in Prishtina to other countries in the world;determine the effect of hereditary and socio-economic factors on the prevalence of myopia;and determine the degrees of myopia in our cases included in our study. Materials and Methods: This was a cross-sectional study involving 1027 pre-school children and pupils from 4 schools in Prishtina, aged 3 - 9 years old, who were screened for refractive anomalies, with a special focus on the incidence of myopia in this age group. The data were collected by screening children in the institutions of pre-school and primary school education, including 2 primary schools and two kindergarten during a two-year period 2010-2012 in Prishtina. Results: On the screening of pre-school and school children for refractive anomalies, were included 1027 subjects of ages 3 - 9 years old. Of the 1027 children screened 536 (52.2%) were male and 491 (47.8%) were female. Statistically, the prevalence of refractive anomalies in the total population studied is significant based on the resulting value (P Conclusions: The Prishtina study is a report of prevalence of myopia among pre-school and school-age children in the municipality. The study reveals that refractive error and myopia were significantly common finding among the study group, and the prevalence was found to be even higher in children within the school age-group. The number of newly diagnosed myopia was significant, suggesting the need for a robust school eye health programme, regular assessment of school children for refractive error and provision of timely refractive corrections.展开更多

However,estimates of the prevalence of such infections among school age children,who bear the greatest health burden due to these diseases,are hard to come by.The objective of this study was therefore to determine the prevalence and type of intestinal helminth infections among primary school pupils.The study was cross-sectional in design.The participants included 266 pupils recruited from three government primary schools in the Mokola area of Ibadan,Nigeria.The pupils were interviewed and their stool samples examined for eggs of common helminths.The mean age of the pupils was 9.8±2.6 years,and 128(48.1%) were males.Nineteen pupils(7.1%) had intestinal helminth infestations.Ascaris lumbricoides was found in 17 pupils(6. 4%) and was the most prevalent helminth among the children,while Trichuris trichiura was found in only two subjects(0.8%).Previous infestations and the use of public toilets were found to be significantly associated with current infections(P【0.05).This study demonstrated that the prevalence of intestinal infections was low among the pupils studied,and that Ascaris infection was the commonest infestation.展开更多

Therefore, the present study aimed to determine the nutritional status and dietary habits of school children. Methods: This is a community based cross-sectional survey designed to evaluate nutritional status of students aged (5 - 19 years) in Beni-Suef Governorate, Egypt, during September-December 2013. A two-stage sampling technique was done;22 government schools were selected in the first stage. In the second stage, 1100 students were selected from the target population of the study. Weight, height, and age data were used to calculate z-scores of the three different nutritional indicators. Dietary habits were studied using a food frequency questionnaire. Results: Underweight (WAZ +2SD). Boys were more underweight (3%) than girls (2.2%). Conversely, girls tend to be more stunted (65.3%) compared to boys (59.9%) in the age group 10 - 14 years. Identified risk factors associated with malnutrition for those aged more than 10 years were: mother education (P-value = 0.03), father education (P-value = 0.04) and family size (P-value = 0.014). Conclusion and Recommendations: Child’s nutritional status is strongly associated with the literacy of both parents and family size. The prevalence of malnutrition can be reduced by implementation of school intervention programs for the socioeconomic development.展开更多

Therefore, ha...Purpose: Poor hygiene practice, inadequate sanitary conditions and lack of awareness of correct mode of transmission are some factors that attribute to high intestinal parasitic infection among children. Therefore, having proper knowledge, good attitude and practice (KAP) against the aforementioned factors can significantly mitigate the spreading of intestinal infection. Methods: The present study was a cross-sectional study which comprised of 127 students who were selected by stratified random sampling. A self-administered questionnaire was used to record KAP of students against intestinal parasitic infection. Total 126 students gave stool samples which were analysed by formol-ether concentration technique. In addition, sewage samples were also collected and analysed for any parasitic load. Statistical data were generated by Chi-square test. Results: A total of 126 stool samples were examined in the study of which 46 (36.50%) were found infected with one or more intestinal parasites. Among the parasites identified, the most common was Hymenolepsis nana with a prevalence rate of 35 (76.0%). Here, most of the students 96 (76.1%) were having poor knowledge about the correct mode of transmission of intestinal parasites. Majority of the students 91 (72.2%) practicing defecation in open air when they are at home, and all 126 (100%) are doing that at school, and significant number of students were not washing hands after defecation. Conclusion: Lack of knowledge regarding mode of transmission and practice of defecation in open air and not washing hands after defecation are issues of great concern, because many parasitic infection have faecal-oral mode of transmission. So, health authorities have to take these issues seriously and action would be vital to resolve it.展开更多

The aim of this study is to examine the association between elevated annual mean concentration of PM2.5 (particulate matter with aerodynamic diameter less than 2.5 micrometers) and surface ozone and asthma prevalence among school children in Japan from 2006 to 2009. Annual rates of asthma prevalence among preschool and school children (5 to 11 years) are obtained from the database of the Ministry of Education, Culture, Sports, Science and Technology—Japan (MEXT). Data on the concentrations of PM2.5 and surface ozone were obtained from 1,183 stations of air quality monitoring distributed in 47 prefectures. Annual means of these concentrations were compared to annual variations in asthma prevalence by using Pearson correlation coefficient. We found different associations between the annual mean concentration of PM2.5 and surface ozone and the annual rates of asthma prevalence among preschool and school children from 2006 to 2009. The positive values of the correlation coefficient in prefectures such as, Gumma, Shimane, and Niigata, are consistent with the previous knowledge. However, significant inverse associations were found in many prefectures. Our study suggests that the association between elevated concentrations of PM2.5 and surface ozone and asthma prevalence among school children in Japan is not strong enough to assume concretely a plausible and significant association.展开更多

文摘Uncorrected refractive error（URE） is a major health problem among school children. This study was aimed to determine the frequency and patterns of URE across 4 gradients of residential densities（urban, exurban, suburban and rural）. This was a cross-sectional study of school children from 3 districts in Yogyakarta and 1 district near Yogyakarta, Indonesia. The information regarding age, sex, school and school grader were recorded. The Snellen＇s chart was used to measure the visual acuity and to perform the subjective refraction. The district was then divided into urban, suburban, exurban and rural area based on their location and population. In total, 410 school children were included in the analyses（urban=79, exurban=73, suburban=160 and rural=98 school children）. Urban school children revealed the worst visual acuity（P〈0.001） and it was significant when compared with exurban and rural. The proportion of URE among urban, suburban, exurban and rural area were 10.1%, 12.3%, 3.8%, and 1%, respectively, and it was significant when compared to the proportion of ametropia and corrected refractive error across residential densities（P=0.003）. The risk of URE development in urban, suburban, exurban, and rural were 2.218（95%CI： 0.914-5.385）, 3.019（95%CI： 1.266-7.197）, 0.502（95%CI： 0.195-1.293）, and 0.130（95%CI：0.017-0.972）, respectively. Urban school children showed the worst visual acuity. The school children in urban and suburban residential area had 2 and 3 times higher risk of developing the URE.
文摘Pain and hospitalization caused a crisis in the child’s life. At the pre-school children, the stress of the disease makes children become less able to cope with separation. As a result, many children show anxious behavior though more vague than toddler age children. Various ways have been conducted by nurses to treat anxiety in children, but the most effective types of the intervention have not be found. Types of intervention that can be done are art therapy and play therapy. This study aims to compare the effects of art therapy and play therapy in reducing anxiety on children who experience hospitalization. A quasi-experimental research design with pre-post test two group design is used. The sample was 23 children pre-school age for art therapy group and 25 children for play therapy with sampling techniques performed purposive sampling. Intervention of art therapy and play therapy each performed for 3 days with duration about 30 minutes. Anxiety levels before and after the intervention were measured by using the facial affective scale. The results show that there is a difference in anxiety between before and after the action in the art therapy group (p = 0.00) and that there are differences in anxiety before and after the action in the play therapy group (0.00). But statistical tests using Man Whitney U indicate that there is no difference in anxiety levels in pre-school children who do art therapy and play therapy (p = 0.26). So, it is concluded that the art therapy and the play therapy can reduce the level of anxiety on pre-school school children that experience hospitalization. Based on these conclusions, it is recommended that the art therapy and the play therapy can be used by nurses and the choice of the intervention should be submitted to the child.

文摘A study on to identify the relationship between blood lead and cognitive development was conducted on primary school children in Malaysia. About 413 children aged 62^/1 - 82^/1 years from urban （236）, rural （80） and industrial areas （97） were studied. Blood lead was analyzed using the Atomic Absorption Spectrophotometer （GFAAS）. Cognitive development was measured by the ＇McCarthy Scales of Children＇s Abilities Test＇ （MSCA）. Significant differences found in the mean cognitive scores between the urban （94.40）, industrial （102.90） and suburban children （101.24） （p 〈 0.001）, with the blood lead between the urban （3.66 p.g/dL）, industrial （3.54 μg/dL） and suburban children （3.04μg/dL） （p = 0.022）. Significant inverse correlations between blood lead and cognitive scores found for all groups （p 〈 0.001）, urban （p 〈 0.001） and suburban children （p 〈 0.001）. Low blood lead significantly influenced the cognitive development for all children after adjusting for confounders （p _〈 0.001）. The urban children＇s cognitive scores were significantly influenced by blood lead levels and household income （p 〈 0.001）. However, for the suburban children, the cognitive score were significantly influenced by the blood lead levels, the mothers＇ education, number of siblings, sequence in the family and the household income （p 〈 0.001 ）. Blood lead below 10μg/dL influenced the cognitive development. Urban children had higher blood lead but suburban children with lower blood lead were also vulnerable to the effect of lead on their cognitive development.
文摘The objectives of this study were to assess the prevalence of students＇ fruit and vegetable intake and its associated factors among adolescents in Mongolia. Data for this analysis were from the 2010 Mongolia Global School-Based Health Survey （GSHS）. The GSHS administered a self-report questionnaire to a nationally representative sample （N = 5,328） of 7th-llth grade school children. Chi-square analyses and multivariate logistic regressions were performed to determine the prevalence and to predict the fruit and vegetable intake from associated factors. Only 7.0% of students met WHO＇s recommendation of eating fruits and vegetables S or more times per day. There was a significant association between gender and fruit and vegetable intake （P = .016）. There was a significant relationship between living condition and fruit and vegetable intake （P =.029）. Students who lived in apartment were more likely to have adequate fruit and vegetable intake than those who lived in ger in the khashaa. To be effective, educational interventions should be implemented as early as possible.

The object ophthalmic examinations were done, included non-cycloplegic objective refraction, visual acuity, intraocular pressure, fundus evaluation by ophthalmologists and nurses with professional training. Specially designed questionnaires were filled in and the data were statistically analyzed with SPSS10.0.Results: Of 11514 eyes, the detection rate was 81.4%(9376eyes) for myopia and 5.3%(615 eyes) for high myopia. High myopia was found in 2.6%.(300 eyes).of right eyes, 2.7%(315 eyes) in left eyes, and 2.4%(275 eyes) were in boys and 2.9%(340 eyes) in girls. Among 12 school grades, the detection rates of high myopia increased significantly with student age, with 0.9% in the 1stgrade of primary school and12.5% in the 3rd year of senior middle school. The average refractive error of spherical equivalent refraction was(-7.43±1.29) D with 95% confidence interval(-7.54,-7.33). No significant differences were found between the right and left eyes or both genders. The distribution of myopic severity was lowest(-6D).in primary school students younger than 12 years,was higher(-8D) in junior middle school students older than13 years, and highest(-13D) in senior middle school students.Conclusion: A continuous growth was evident in the severity of high myopia throughout 12 years of primary and middle school except for the first year of primary school, with growth occurring in two transitional stages between the senior primary and junior middle school years, and between the junior and senior middle school years. The distribution of high myopia was lowest, at-6D, in primary school, increased to-8D in junior middle school, and progressed to-10D in senior middle school, indicating a high risk of development of pathologic myopia during the students’ later lifespan. The adolescent period of 13 to 18 years of age in middle school is a critical period for the development of pathological myopia over-8D.
文摘Obesity is on the rise in developing countries, especially in urban areas. In this study, a cross-sectional study was conducted in two divisions in Nairobi province to determine the prevalence of and some risk factors associated with overweight and obesity among school children in Nairobi, Kenya. It involved 344 school children aged 9-14 years drawn from four randomly selected public and private primary schools. Weight and height were measured and body mass index was calculated. Nutrition status was determined using the World Health Organization age and gender specific BMI-for-age Z-scores (BAZ). The chi-square test was used to determine the relationship between overweight/obesity and selected socio-demographic characteristics. Complete anthropometric measurements were available for 321 children. Prevalence of combined overweight and obesity (BAZ > +1SD) was 19.0%, with prevalence being higher among girls (21.0%) than boys (16.9%) (p = 0.632). The prevalence among children in private schools was significantly higher (29.0%) than among those in public schools (11.5%) (p = 0.000). In addition, being a single child (p = 0.020), birth order (p = 0.017), mother’s occupation (p = 0.023) and type of residence (p = 0.028) were positively associated with overweight/obesity. The prevalence of overweight/obesity determined in this study is high and is a public health concern, with girls particularly at risk of becoming overweight.
文摘Introduction: Myopia is the refractive anomaly of the eye in which the conjugate focus of the retina is at some finite point in front of the eye, when the eye is not accommodating. Myopia is else known as short-sightedness and is considered as one of the most frequent causes of reduced vision especially in adolescents. Adolescence is one of the life periods when most cases are diagnosed with myopia. Purpose: The aim of this study was to identify myopia in pre-school and school children (3 - 9 years old in Prishtina), to determine the prevalence of myopia among other refractive anomalies in cases included in the study;compare the prevalence of myopia in this population in Prishtina to other countries in the world;determine the effect of hereditary and socio-economic factors on the prevalence of myopia;and determine the degrees of myopia in our cases included in our study. Materials and Methods: This was a cross-sectional study involving 1027 pre-school children and pupils from 4 schools in Prishtina, aged 3 - 9 years old, who were screened for refractive anomalies, with a special focus on the incidence of myopia in this age group. The data were collected by screening children in the institutions of pre-school and primary school education, including 2 primary schools and two kindergarten during a two-year period 2010-2012 in Prishtina. Results: On the screening of pre-school and school children for refractive anomalies, were included 1027 subjects of ages 3 - 9 years old. Of the 1027 children screened 536 (52.2%) were male and 491 (47.8%) were female. Statistically, the prevalence of refractive anomalies in the total population studied is significant based on the resulting value (P Conclusions: The Prishtina study is a report of prevalence of myopia among pre-school and school-age children in the municipality. The study reveals that refractive error and myopia were significantly common finding among the study group, and the prevalence was found to be even higher in children within the school age-group. The number of newly diagnosed myopia was significant, suggesting the need for a robust school eye health programme, regular assessment of school children for refractive error and provision of timely refractive corrections.
文摘Objective:To determine the disease prevalence and its relationship with hepatitis B and C viruses among school children in five endemic areas by schistosomiasis.Methods:During June 2007 and March 2009,1 484 school children aged between 5-16 years participated in the current study from 32 basic schools in five districts(Al-Dhabab,Hedran,Warazan,Al-Barh and Al-Shmaytin) in Taiz Governorate,Republic of Yemen.Out of school children who participated in the study;1 406 stool samples,1 484 urine samples and 214 blood samples were collected and examined.Results:Schistosoma mansoni(S.mansoni) was found in all the studied areas except Al-Barh.However,Schistosoma haematobium(S.haematobium) was recorded only in Al-Shmaytin and Al-Barh.Both S.mansoni and S.haematobium were observed in Al-Shmaytin district.The overall prevalence was 20.76%for S.mansoni and 7.41%for S.haematobium. The prevalence rate of infection among males was higher than females,shwing no significant differences.Rate of light,moderate and heavy infections in the case of S.mansoni were 41.78%, 25.34%and 32.87%respectively.Whereas,for S.hematobium it was 50.90%for light infection and 49.09%for heavy infection.Regarding to the prevalence of viral hepatitis among infected school children with schistosomiasis,it could be noticed that hepatitis B virus was higher than the prevalence of hepatitis C virus.But,the presence of HBsAg and anti-HCV was not associated with Schistosoma infection.Conclusions:Schistosomiasis infection is an important public health problem in Taiz Governorate,Republic of Yemen.There was a correlation between S. haematobium and hepatitis B,but no association between 5.mansoni infections and hepatitis B and C viruses.
文摘Despite a substantial reduction in the incidence and prevalence of parasitic diseases in the industrialized world, they continue to be an important public health problem in many developing African countries,including Nigeria. However,estimates of the prevalence of such infections among school age children,who bear the greatest health burden due to these diseases,are hard to come by.The objective of this study was therefore to determine the prevalence and type of intestinal helminth infections among primary school pupils.The study was cross-sectional in design.The participants included 266 pupils recruited from three government primary schools in the Mokola area of Ibadan,Nigeria.The pupils were interviewed and their stool samples examined for eggs of common helminths.The mean age of the pupils was 9.8±2.6 years,and 128(48.1%) were males.Nineteen pupils(7.1%) had intestinal helminth infestations.Ascaris lumbricoides was found in 17 pupils(6. 4%) and was the most prevalent helminth among the children,while Trichuris trichiura was found in only two subjects(0.8%).Previous infestations and the use of public toilets were found to be significantly associated with current infections(P【0.05).This study demonstrated that the prevalence of intestinal infections was low among the pupils studied,and that Ascaris infection was the commonest infestation.
文摘Objective:To determine the prevalence,sex-age related intensity of urinary schistosomiasis and to compare such parameters among rural school children and rural fanners in selected communities in Obollo-Eke located in Southeast,Nigeria.Methods:A cross-sectional survey involving 1 337 school children and farmers was conducted in Obollo-Eke community between September 2006 and July 2007.Demographic data of subjects was collected using a questionnaire prepared for this purpose.Urine samples were collected and examined for haematuria and ova of Schistosoma haematobium(S.haematobium) using Medi-test Combi 9 and sedimentation technique respectively.Results:The prevalence of urinary schistosomiasis based on microscopic examination of the urine sediment for the ova of 5.haematobium was 17.5%while the prevalence of haematuria was 15.6%.Infection intensity varied from light to heavy.In general,the prevalence was higher among males(20.8%) than females(14.6%;P】0.05) and was slightly higher among primary school children(18.0%;n=762) than farmers(16.9%;n=575;P】0.05).The age-specific prevalence of schistosomiasis among the study subjects ranged from 8.3%to 21.2%in 0-5 years and 11-15 years age groups respectively.Conclusions:Haematuria and mean egg/10 mL urine (r = 0.95;P【0.01) showed that both procedures are reliable for the diagnosis of the disease and can be used to ascertain the prevalence of the disease in any community.The comparative analysis of urinary bilharziasis among primary school children and rural farmers demonstrated that the infection is moderately high in these two risk population groups at Obollo-Eke.A robust intervention strategy is clearly needed.
文摘Objectives: Childhood malnutrition is a major concern in developing countries. Therefore, the present study aimed to determine the nutritional status and dietary habits of school children. Methods: This is a community based cross-sectional survey designed to evaluate nutritional status of students aged (5 - 19 years) in Beni-Suef Governorate, Egypt, during September-December 2013. A two-stage sampling technique was done;22 government schools were selected in the first stage. In the second stage, 1100 students were selected from the target population of the study. Weight, height, and age data were used to calculate z-scores of the three different nutritional indicators. Dietary habits were studied using a food frequency questionnaire. Results: Underweight (WAZ +2SD). Boys were more underweight (3%) than girls (2.2%). Conversely, girls tend to be more stunted (65.3%) compared to boys (59.9%) in the age group 10 - 14 years. Identified risk factors associated with malnutrition for those aged more than 10 years were: mother education (P-value = 0.03), father education (P-value = 0.04) and family size (P-value = 0.014). Conclusion and Recommendations: Child’s nutritional status is strongly associated with the literacy of both parents and family size. The prevalence of malnutrition can be reduced by implementation of school intervention programs for the socioeconomic development.
文摘Purpose: Poor hygiene practice, inadequate sanitary conditions and lack of awareness of correct mode of transmission are some factors that attribute to high intestinal parasitic infection among children. Therefore, having proper knowledge, good attitude and practice (KAP) against the aforementioned factors can significantly mitigate the spreading of intestinal infection. Methods: The present study was a cross-sectional study which comprised of 127 students who were selected by stratified random sampling. A self-administered questionnaire was used to record KAP of students against intestinal parasitic infection. Total 126 students gave stool samples which were analysed by formol-ether concentration technique. In addition, sewage samples were also collected and analysed for any parasitic load. Statistical data were generated by Chi-square test. Results: A total of 126 stool samples were examined in the study of which 46 (36.50%) were found infected with one or more intestinal parasites. Among the parasites identified, the most common was Hymenolepsis nana with a prevalence rate of 35 (76.0%). Here, most of the students 96 (76.1%) were having poor knowledge about the correct mode of transmission of intestinal parasites. Majority of the students 91 (72.2%) practicing defecation in open air when they are at home, and all 126 (100%) are doing that at school, and significant number of students were not washing hands after defecation. Conclusion: Lack of knowledge regarding mode of transmission and practice of defecation in open air and not washing hands after defecation are issues of great concern, because many parasitic infection have faecal-oral mode of transmission. So, health authorities have to take these issues seriously and action would be vital to resolve it.
文摘Researches on asthma have found that air pollution increased asthma prevalence among sensitive age groups, including school children, and exposed them to the recognized health impacts. The aim of this study is to examine the association between elevated annual mean concentration of PM2.5 (particulate matter with aerodynamic diameter less than 2.5 micrometers) and surface ozone and asthma prevalence among school children in Japan from 2006 to 2009. Annual rates of asthma prevalence among preschool and school children (5 to 11 years) are obtained from the database of the Ministry of Education, Culture, Sports, Science and Technology—Japan (MEXT). Data on the concentrations of PM2.5 and surface ozone were obtained from 1,183 stations of air quality monitoring distributed in 47 prefectures. Annual means of these concentrations were compared to annual variations in asthma prevalence by using Pearson correlation coefficient. We found different associations between the annual mean concentration of PM2.5 and surface ozone and the annual rates of asthma prevalence among preschool and school children from 2006 to 2009. The positive values of the correlation coefficient in prefectures such as, Gumma, Shimane, and Niigata, are consistent with the previous knowledge. However, significant inverse associations were found in many prefectures. Our study suggests that the association between elevated concentrations of PM2.5 and surface ozone and asthma prevalence among school children in Japan is not strong enough to assume concretely a plausible and significant association.
文摘Background: Self-cleaning of ears with different objects is a common practice among school children with scanty report in literature. Aim: The aim of this study was to determine the prevalence and profile of self-ear cleaning among school children. Methods: It was a cross-sectional institutional-based study which was carried out among school children in Ekiti, south western Nigeria from January 2017, to March 2017. Results: A total of 174 students participated in this study. Their age ranged between 13 and 17 years. The highest number of participant was found at the age of 15 years. One hundred and eighteen (67.8%) of them had carried out self ear cleaning. Personal hygiene was the commonest reason for self ear cleaning in 28.8% of the students. Cotton buds were mostly used by the respondents in 51.7% of them. Injury to the external auditory canal (EAC) was the most recorded complications. Conclusion: The outcome of this study shows that self-ear cleaning practices were common among school children with a prevalence of 67.8%. Cotton buds were the commonest objects used. Avoidable complications were reported among respondents. There is a need to intensify efforts on public enlightenment programme and the establishment of school health programme in our various schools.
