选择枫林街道1990年1月～1992年12月出生的小儿共369人,男性175人,女性194人.根据不同喂养方式分为纯母乳喂养组(146人)和人工喂养组(223人).观察小儿出生1～6、9和I2个月的体重、身长、头围、胸围和中上臂围,计算体重和身长的逐月、6～9和9～12个月增值,比较两组贫血、佝偻病和前后半年的呼吸道感染和腹泻的发病率.以女性为例人工组体重自4个月起超过母乳组,到9和12个月达到显著意义.身长自 3个月起超过母乳组,差异有显著性.胸围和臂围分别在5和12个月时超过.除了第1个月外人工组的体重增值略均大于母乳组,自6个月起差异有显著性.前半年人工组的身长增值大于母乳组,在2、3个月时有显著性.男性小儿的生长情况和女性相似.贫血发病率两组无差异.但佝倭病和前半年的呼吸道感染人工组显著高于母乳组.全年的腹泻和后半年的呼吸道感染次数两组无差异.提示应鼓励母乳喂养,尤其在生后最初几个月.4个月起应及时添加辅食,随着母乳量的减少,乳制品的添加也不能忽视.
