【摘要】 重点分析了中国城市与农村 4个月以内婴儿纯母乳喂养情况及其与婴儿生长发育及疾病的关系。资料来源于 1 998年全国 40个食物与营养监测点现场调查。通过分析表明中国 4个月以内婴儿纯母乳喂养率城市为 53.7% ,一般农村为 76.6% ,较贫困农村为 64.6%。生长迟缓婴儿的纯母乳喂养率为 57.7% ,显著低于身长正常的儿童 73.0 %。4个月以内采用纯母乳喂养的婴儿比非纯母乳喂养的婴儿体重平均重 0 .36kg,身长平均高 1 .2 cm,WAZ值高 0 .4,HAZ高0 .53,相差显著。同时 ,纯母乳喂养的婴儿腹泻患病率显著低于非纯母乳喂养的婴儿 ,两者相差1 5.9个百分点。通过 Logistic回归分析显示 ,非纯母乳喂养的婴儿发生生长迟缓的危险度为纯母乳喂养的婴儿的 2 .1 9倍 (OR=2 .1 9) ,发生腹泻的危险度为 2 .74倍 (OR=2 .74)更多还原

【Abstract】 Data collected at the 40 CFNSS sites in 1998 was analyzed on the relationship of exclusive breastfeeding and the growth, diseases of infant aged under 4 months. The results showed that the exclusive breastfeeding rates (EBF) of children under 4 months were 53 7% in urban and 76 6% in general rural, but was 64 6% in the poor rural. EBF rate of the stunted children was 57 3% that was significantly lower than the infants with normal length.73 0%. The infants EBF under 4 months were 0 36kg heavier, 1 2 cm longer, and WAZ 0 4 and HAZ 1 53 higher than the non EBF infants. Prevalence of diarrhea were 13 1% among EBF and 29% in non EBF infants.Logistic regression analysis showed that odds ratio (OR) of stunting for non-EBF infants was 2 19, OR of diarrhea was 2 74更多还原
