以体重、身高、头围、胸围为“因变量”,母乳量、食物添加、食欲、疾病、出生体重、孕周、性别为“自变量”,对上海县七宝、莘庄镇728名儿童在生后1、3、6、9、12、18、24和35个月时的体格发育状况,分别作典型相关分析。结果提示:提高四个月内的纯母乳喂养率,有益于改善当地婴儿早期的体格发育水平,而适当延长喂乳期(如至12个月左右)、适时添加辅食,尤其是天然的高蛋白食品、保持良好食欲及预防腹泻和贫血,对增进儿童的体格发育尤有意义。
A total of 728 children in Shanghai Qibao and Xinzhuang were surveyed with weight, height, head circumference and chest circumference as “dependent variables”, breast milk volume, food intake, appetite, disease, birth weight, gestational age and sex as independent variables Postprandial physical development at 1, 3, 6, 9, 12, 18, 24 and 35 months were analyzed by canonical correlation. The results suggest that increasing the rate of exclusive breastfeeding within four months will help to improve the early stage of physical development in infancy while appropriately prolonging the feeding period (up to about 12 months) and adding complementary foods, especially natural high-protein Food, maintaining good appetite and preventing diarrhea and anemia, especially for the promotion of children’s physical development.
