Breast-feeding and artificial feeding practices in a developing country were examined and related to some social and developmental factors. This was done during the course of a transverse-type growth study of 1,000 infants from birth to 26 months of age. Three types of feeding were identified: breast, mixed, and artificial. The families were divided into three social categories. To give time for the effects of the type of feeding, groups of children at 6, 8, 10, 12, 14, and 16 months of age were studied. In view of the lack of data on feeding effects upon large samples, the study was performed to assess the relative effects of feeding on early childhood development (Bayley Motor and Mental Scales), body length and weight, disease prevalence, clinical signs of allergies, and number of children in the family. Results showed that within the underprivileged group, there was evidence that breast-feeding promoted physical growth, sensory motor development, and resistance to infection. In mothers of both male and female infants who breast-fed, there was a protective effect against subsequent pregnancy up to ten months. Therefore, among the underprivileged in developing countries, every effort should be made to prolong breast-feeding and to assist mothers with health and nutrition education.
对一个发展中国家的母乳喂养和人工喂养方式进行了调查，并将其与一些社会和发育因素联系起来。这是在对1000名从出生到26个月大的婴儿进行横向生长研究的过程中完成的。确定了三种喂养方式：母乳喂养、混合喂养和人工喂养。这些家庭被分为三个社会类别。为了有时间观察喂养方式的影响，对6、8、10、12、14和16个月大的儿童组进行了研究。鉴于缺乏关于大样本喂养影响的数据，进行这项研究是为了评估喂养对幼儿发育（贝利运动和智力量表）、身长和体重、疾病患病率、过敏临床症状以及家庭中孩子数量的相对影响。结果表明，在贫困群体中，有证据表明母乳喂养促进了身体生长、感觉运动发育和抗感染能力。在母乳喂养的男婴和女婴的母亲中，在随后长达十个月的时间里对再次怀孕有保护作用。因此，在发展中国家的贫困群体中，应尽一切努力延长母乳喂养时间，并协助母亲进行健康和营养教育。
