摘要
目的:了解江西省农村儿童体格发育水平及营养不良的患病率。方法:通过整群抽样调查江西省农村9238例儿童,所有儿童均由统一培训人员测量身高、体重,以WHO/NCHS标准为参数评价儿童体格发育水平,计算年龄别身高Z值(HAZ)、年龄别体重Z值(WAZ)和身高别体重Z值(WHZ)。分别计算儿童生长迟缓、低体重、消瘦的患病率。结果:我省农村儿童体格发育水平6月以内可达甚至超过WHO标准,6月龄后开始滞后。6月龄内儿童Z值主要分布在0～1和-1～0两个区间;6月龄后逐渐向左移,Z值主要分布于-1～0和-1～-2两个区间。儿童HAZ和WAZ主要分布在-1～0和-1～-2两个区间;而WHZ则以0～1和-1～0两个区间为主。生长迟缓、低体重和消瘦的患病率分别是13.2%、13.0%和2.9%,出生后6月内营养不良检出率最低,以后随年龄增长检出率逐渐增加,生长迟缓率在18～24月龄时达高峰。结论:我省农村儿童体格发育水平与WHO标准仍有一定差距,提示应进一步提高农村卫生水平和加强健康教育,有效改善农村儿童营养状况。
Objective： To assess physical growth and prevalence rates of malnutrition for children under 7 years in rural area of Jiangxi province. Methods： A cross - sectional study was conducted in 9 238 children under 7 years with random sampling. The height and weight were measured by professional staffs, the physical growth was evaluated with WHO/NCHS reference using Z scores. Results： The physical growth was no lower than WHO/NCHS reference among children younger than 6 months, then fell after 6 months. The Z scores were most distributed between - 1 ~ 1 of children less than 6 months, then shifted downward to - 2 - 0 after 6 months. The distributions of Z scores of height for age （HAZ） and Z scores of weight for age （WAZ） were almost between - 2 ~ 0, and Z scores of weight for height （WHZ） was between - 1 ~ 1. The prevalence of stunting, underweight and wasting were 13. 2%, 13. 0% and 2. 9%, respectively; the prevalence of malnutrition was lowest in infants younger than 6 months ; the prevalence of stunting was highest in 18 ~ 24 months. Conclusion： The growth of the children still has some defect compared with WHO standard. Improving socioeconomic level and health education could diminish and escape malnutrition of children.
