中国较贫困农村婴幼儿喂养方式及其与生长发育的关系

Feeding patterns and it′s relationship with growth of children in relatively poor rural areas of china

对１９８５～１９８９年７省１８个乡较贫困农村婴幼儿喂养方式、生长发育监测结果进行分析。４月龄时母乳喂养率为７４．８％，混合喂养率为２２．０％。农村儿童平均断奶年龄为１８．２月，混合喂养儿的断奶年龄较母乳喂养儿早３个月。４个月时母乳喂养儿的身长、体重及血红蛋白水平高于混合喂养儿，混合喂养儿又高于人工喂养儿。低体重和低矮儿童发生率也是母乳喂养组低于混合喂养组及人工喂养组，差别极显著。因此鼓励提倡母乳喂养是农村改善儿童营养状况的有效途径之一。

The information of feeding patterns and growth of rural preschool children of 18 relatively poor study sites in 7 provinces was collected from 1985 to 1989 and analyzed. The breast feeding rate at 4 months was 74.8%,Mixed feeding rate was 22%. The average weaning age of these rural children was 18. 2 months. The weaning time of mixed fed children was 3 months earlier than those of breast fed children.At 4 months,the height,weight and hemoglobin level of breast fed children were better than those of mixed fed children and the mixed fed children were better than those of bottle fed children. The prevalence of under weight and stunting among the breast fed children was lower than those among mixed fed and bottle fed children.The differences were significant.Therefore promoting breast feeding is one of the effective ways to improve the nutritional status of children in rural areas.
