摘要
目的了解西藏自治区农村地区3岁以下儿童营养状况,为改善西藏自治区儿童营养状况提出合理化建议。方法采用人口比例抽样法获得调查对象。自行设计调查问卷,对6个地区15个项目县72个乡镇的1 513名儿童母亲进行面对面问卷调查。以年龄别身高Z评分(HAZ)、年龄别体重Z评分(WAZ)和身高别体重Z评分(WHZ)作为儿童营养状况的评价指标。结果项目地区儿童生长迟缓(HAZ<-2)、低体重(WAZ<-2)和消瘦(WHZ<-2)的患病率分别为33.9%,16.5%和3.4%。不同地区及性别儿童营养不良患病率不同,男童低体重患病率明显高于女童,差异有统计学意义(P<0.01)。在海拔4 500m以上,生长迟缓和低体重的患病率分别达36.5%和19.1%。结论西藏农村地区3岁以下儿童营养状况不容乐观,应根据影响儿童营养状况的相关因素采取干预措施,改善儿童营养状况,降低各种营养不良患病率。
Objective To investigate the nutrition status and its influencing factors among children under three years old in rural area of Tibet, so as to provide reasonable suggestions for policy making. Methods The proportion population sampling（PPS） method was used to investigate 1513 children under three years old in 72 townships of 6 regions. HAZ, WAZ and WHZ were used as nutritional indexes. Results The prevalence of stunting（height for age Z - score 〈 - 2）, underweight （weight for age Z - score 〈 - 2） and wasting（weight for height Z - score 〈 - 2） was 33.9 %, 16.5 % and 3.4 %, respectively. Different gender and regions had different prevalence of malnutrition, and the stunting and underweight prevalence in the area of 4 500 meters above the sea level were 36.5 96 and 19.1%, respectively. The underweight prevalence rate in boys was much higher than that of in girls（P 〈 0.01）. Conclusion Malnutrition is prevalent among children in Tibet. The intervention should be done according to the influence factors.
