目的研究经济社会因素对农村中小学生营养状况的影响,为改善农村中小学生营养状况提出有效措施。方法随机抽取湖南3类地区中各1个县/区的1所乡镇中学和小学,共9所学校960名学生为研究对象,现场测量学生身高、体重,发放并回收调查问卷。结果学生生长迟缓检出率第二类地区最高,为15.20%(χ2=10.33,P<0.05);父、母月收入<2 000元最高,分别为23.53%,19.35%(χ2值分别为23.61,15.38,P值均<0.01);父、母受教育程度小学及以下最高,分别为22.63%,16.16%(χ2值分别为18.22,14.67,P值均<0.01)。第三类地区学生消瘦的比例最高,为19.81%(χ2=13.58,P<0.01);第一类地区学生超重和肥胖的比例最高,为21.47%(χ2=12.16,P<0.01),呈明显的两极分化。结论不同经济发展水平地区的中小学生营养状况差异有统计学意义,父母文化程度高低、收入水平高低等因素都对学生营养状况有明显影响,应针对不同情况分别做出相应的改善措施。
Objective To study the impact of economic and social factors on the nutritional status of primary and secondary school students in rural areas and to put forward effective measures to improve the nutritional status of rural primary and secondary school students. Methods A total of 960 students from 9 townships were selected from 1 township primary school and 1 primary school in 1 county / district in Hunan Province. The students’ height and weight were measured on the spot, and the questionnaires were distributed and collected. Results The detection rate of stunting was the highest in the second category, which was 15.20% (χ2 = 10.33, P <0.05). The monthly income of parents and mothers was the highest (<2 000 yuan, 23.53% and 19.35%, respectively) , 15.38, P <0.01). The highest educational level of both parents and their parents was 22.63% and 16.16% respectively (χ2 = 18.22 and 14.67, P <0.01 respectively). The proportion of students in the third category was the highest, accounting for 19.81% (χ2 = 13.58, P <0.01). The percentage of students who were overweight and obese in the first category was the highest (21.47%, χ2 = 12.16, P <0.01) Polarization. Conclusion The nutritional status of primary and middle school students in different levels of economic development have statistical significance. Factors such as parents ’educational level, income level and so on have obvious influence on students’ nutritional status. Corresponding improvement measures should be made according to different situations.
