摘要
目的分析2012-2016年四川省农村中小学生营养状况及变化趋势,为进一步完善农村学生营养改善政策提供参考。方法连续5年对四川省实施农村学生营养改善计划的试点县开展学生营养健康状况监测,评估监测学生营养状况及变化趋势。结果连续5年男生、女生生长迟缓率呈逐年下降趋势(χ_(趋势)~2分别为1 941.55、1 696.52,P<0.01);男生消瘦率随学年度变化趋势无统计学意义(χ_(趋势)~2=1.44,P=0.23),女生消瘦率从2013年起总体呈下降趋势(χ_(趋势)~2=70.04,P<0.01);男生、女生超重率和肥胖率均呈上升趋势(χ_(趋势)~2分别为46.67、74.51、294.97、165.16,P<0.01)。结论四川省农村中小学生营养不足状况有所改善,营养过剩状况在增加,提示在加大农村地区学生营养改善投入力度的同时,还应加强校园科学配餐能力和学生食欲,提倡吃动平衡、合理膳食。
Objective To investigate the nutritional status and its trend in primary and middle school students in Sichuan rural areas from 2012 to 2016 in order to provide reference for further intervention policies. Methods The status and the trend of nutrition in students were assessed among pilot counties carrying out the nutrition improvement program in Sichuan during the five years. Results The prevalence of growth retardation kept declining both on a yearly basis in male and female students（ χ^2= 1 941. 55,1 696. 52,P〈0. 05）. The prevalence of emaciation in female students has been declining since the year 2013（ χ^2= 70. 04,P〈0. 05）,but no significant variation trend was found in male students（ χ^2= 1. 44,P = 0. 23）. Overweight and obesity prevalence kept rising in both male and female students during the five years（ χ^2= 46. 67,74. 51,294. 97,165. 16,P〈0. 05）. Conclusion The status of nutrition deficiency in rural primary and middle school students in Sichuan has been improved but the status of over-nutrition has worsened. It is suggested that we should not only increase the investment to the nutrition improvement program in rural schools,but also enhance the scientific catering capability of schools and carry out nutrition education in students,advocate balance between food intake and exercise and promote rational diets.
