This study was undertaken to determine the prevalence and associated factors of sexual violence among female private college students in Bahir Dar city. Methods: A cross sectional study was conducted in April 2012 among 541 female college students in Bahir Dar city using multistage sampling technique. A pretested self-administered questionnaire was used. The data were analyzed in bivariate and multivariate logistic regression analysis with SPSS version 16 soft ware package. Result: The study revealed that the prevalence of sexual violence among female college students was 37.3%. Respondents whose childhood background from rural areas were more than four times likely to have had sexual violence (AOR = 4.51, 95%CI: 1.67 - 12.16). The odds of sexual violence were higher for those respondents who had a close friend who drank alcohol (AOR = 3.13, 95%CI: 1.09 - 8.97). Besides, respondents who had never discussed on reproductive health issues with their parents were more than four times likely to have had sexual violence (AOR = 4.36, 95%CI: 1.40 -13.56). Conclusion: This study shows that sexual violence among female college students is higher. Sexual violence is associated with certain variables such as rural childhood residence, having a close friend who drank alcohol, and not discussing reproductive issues with parents. Therefore, it is recommend ed that sexual violence needs due attention and remedial action from policy makers, college officials, parents, students and other concerned bodies.展开更多

Institution based cross-sectional study was carried out. A total of 337 women of reproductive age group with disabilities were included in the study with simple random sampling. Data were collected through face-to-face interview, coded, cleaned and entered by Epi info 2002 and analyzed with SPSS version 16 computer software. Logistic regression was used to assess possible associations. The magnitude of unmet need for family planning among women with disabilities was 24.3%. Women with disabilities in the age group of 25-29 had 80% less likely to have unmet need than women above 35 years old. Women with disability who have no education were 11 times more likely to have unmet need than those who have secondary education. Women who desire to have more than 3 children have more likely to have unmet need than those who need to have 1-2 children. Unmet need for family planning among women with disabilities was high in Bahir Dar town. Age, Educational status and desired number of children were found to have statistically significant association with unmet need for family planning. Hence, it is important to encourage people with disabilities to attained formal education and the associations should provide short term trainings in accordance with their age group.展开更多

In Ethiopia construction industry is on increasing and deriving young people from rural area to the cities. Therefore, the aim of this study was to determine the prevalence of risky sexual behaviour and factors associated with among construction workers. Methods: A cross sectional study was conducted in March 2012 among construction workers in Bahir Dar city. The analysis was carried out using SPSS version 16. The data were analyzed in bivariate and multivariate logistic regression. Result: The prevalence of risky sexual behavior among construction workers was 44.9%. Female workers were about four times more likely to have had risky sexual practices than males (AOR = 3.86, 95% CI: 2.34 - 6.37). Respondents whose educational level less than fourth grade were 12 times more likely to be engaged in risky sex than whose educational level tenth grade or more (AOR = 12.13, 95% CI: 1.84 - 79.78). Divorced individuals were about five times more likely to have had risky sexual activities than married individuals (AOR = 4.63, 95% CI: 1.32 - 16.12). Respondents whose first sexual commencement from 15 - 19 years were about three times more likely to have had risky sexual behavior than from 20 - 24 years (AOR = 2.89, 95% CI: 1.70 - 4.91). Besides, the odds of having risky sexual behaviour among construction workers who had sexual partner at the time of the study were about 0.6 times less likely to have had risky sexual behaviours than workers who did not have (AOR = 0.6, 95% CI: 0.38, 0.96). Conclusion: The prevalence of risky sexual behavior among construction workers was 44.9%. Variables such as sex, educational level, marital status, age at first sexual intercourse, presence of current sexual partner and casual sex were found to be independent predictors of risky sexual behaviour. Therefore, interventions targeting on these factors were recommended.展开更多

We propose a seasonal mean and volatility model that describes the daily average temperature behavior using the mean-reverting Ornstein-Uhlenbeck process. We also use higher order continuous-time autoregressive process with lag 3 for modeling the time evolution of the temperatures after removing trend and seasonality. Our model is fitted to 11 years of data recorded, in the period 1 January 2005 to 31 December 2015, Bahir Dar, Ethiopia, obtained from Ethiopia National Meteorological Services Agency. The analytical approximation formulas are used to price heating degree days(HDD) and cooling degree days(CDD) futures. The suggested model is analytically tractable for derivation of explicit prices for CDD and HDD futures and option. The price of the CDD future is calculated, using analytical approximation formulas. Numerical examples are presented to indicate the accuracy of the method. The results show that our model performs better to predict CDD indices.展开更多

Methods: A hospital based cross-sectional study was designed to determine the prevalence of toxoplasmosis among pregnant women. Three hundred eighty four serum samples were collected from November 2013 to January 2014. Data on socio-demographic and predisposing factors were collected from each study participant with simple random sampling technique. The serum samples were examined for anti- Toxoplasma gondii(T. gondii) antibodies using latex agglutination test. Results: The overall seroprevalence of T. gondii among the pregnant women was 18.5%. All of T. gondii positive cases found to be positive only for Ig G antibody. Significant association was observed between seroprevalence and presence of domestic cats [AOR=2.85, 95% CI: 1.66-4.90, P=0.000], consumption of raw or undercooked meat [AOR=1.98, 95% CI: 1.15-2.43, P=0.014] and history of abortion [AOR=2.47, 95% CI: 1.40-4.34, P=0.002]. No significant association was observed between seroprevalence and socio-demographic characters, gestational age, gravidity, consumption of raw vegetable, and blood transfusion. Conclusions: The seroprevalence of toxoplasmosis among pregnant women in Bahir Dar town was relatively high. Presence of domestic cats at home and consumption of raw or undercooked meat were identified as main risk factors for T. gondii infection. Therefore, health education towards avoiding eating raw or undercooked meat and avoiding contact with cats are recommended for prevention of miscarriage or defects during pregnancy.展开更多
