OBJECTIVE
To observe the effect of 6-23 months infants by Yingyangbao(YYB) intervention in impoverished areas of Henan Province.
METHODS
A multi-stage random sampling method was used to select infants aged 6-23 months from 51 project counties in Henan Province from September to November 2019. Physical anthropometric measurement and hemoglobin detection were performed, and face-to-face questionnaires surveyed with caregivers of the children. Children in 12 regions covered by YYB were defined as intervention group, and controls were selected from the baseline survey of children in 39 regions not covered by YYB according to the 1∶1 matching principle. The analysis between YYB and control groups were analyzed by χ2 or t test. χ2 test for trend to compare trend of children health status.
RESULTS
A total of 7738 subjects were selected in the study, including 3869 in the intervention group and 3869 in the control group. The average length, weight and hemoglobin level of YYB group were 1. 1 cm, 0. 67 kg and 3. 8 g/L, respectively, which were higher than that of the control group. The anemia rate, underweight rate, stunting rate and wasting rate in intervention group were 13.1%, 1.7%, 2.1% and 1.9%, respectively, significantly lower than control group. Compared with the control group, the two-week prevalence of fever and diarrhea in the intervention group decreased by 5. 6% and 7. 2%, respectively. In addition, nutrition knowledge score of the parents, minimum dietary diversity rate, minimum meal frequency rate and minimum acceptable diet rate of intervention group were 62. 4%, 71. 1%, 73. 7% and 55. 8%, respectively, significantly better than that of control group. From 2015 to 2019, the anemia rate, underweight rate, stunting rate of children in regions covered by YYB showed a downward trend.
CONCLUSION
YYB can effectively improve the nutrition, physical development and health status of 6-24 months infants. Through the implementation of the project, the knowledge and skills of scientific feeding in impoverished regions were significantly improved.
目的
观察营养包（YYB）干预对河南省贫困地区6至23个月婴儿的影响。
方法
采用多阶段随机抽样方法，于2019年9月至11月从河南省51个项目县中选取6至23个月的婴儿。进行体格测量和血红蛋白检测，并对儿童看护人进行面对面问卷调查。将营养包覆盖的12个地区的儿童定义为干预组，根据1∶1匹配原则，从营养包未覆盖的39个地区的儿童基线调查中选取对照组。采用χ²检验或t检验分析营养包组与对照组之间的差异。采用χ²趋势检验比较儿童健康状况的变化趋势。
结果
本研究共纳入7738名受试者，其中干预组3869名，对照组3869名。营养包组的平均身长、体重和血红蛋白水平分别比对照组高1.1厘米、0.67千克和3.8克/升。干预组的贫血率、低体重率、生长迟缓率和消瘦率分别为13.1%、1.7%、2.1%和1.9%，显著低于对照组。与对照组相比，干预组发热和腹泻的两周患病率分别降低了5.6%和7.2%。此外，干预组家长的营养知识得分、最小饮食多样性率、最小进餐频率率和最小可接受饮食率分别为62.4%、71.1%、73.7%和55.8%，显著优于对照组。2015年至2019年，营养包覆盖地区儿童的贫血率、低体重率、生长迟缓率呈下降趋势。
结论
营养包可有效改善6至24个月婴儿的营养状况、身体发育和健康状况。通过实施该项目，贫困地区科学喂养的知识和技能得到显著提高。
