目的 了解农村4月龄内婴儿体格生长的主要影响因素及母乳喂养对体格生长的作用。方法 应用科技部基础性工作专项课题“中国母乳喂养婴儿生长速率监测及标准值研究”中六省农村地区4月龄内婴儿体格发育纵向随访数据,构建年龄别体重、身长和体质指数的多水平模型。结果 婴儿年龄、性别、出生体重、出生身长、产次、母亲年龄、父母身高、季节、喂养方式以及年龄和喂养方式的交互效应与体格生长有关,差异均有统计学意义(P均<0.05)。结论 与婴儿一般情况、家庭人口学特征、父母生物学特征、母亲围生期因素这些不可变因素相比,选择母乳喂养是促进农村4月龄内婴儿体格生长的有效措施。
Abstract
Objective To explore the determinants of growth and effects of breastfeeding for 4 months old infants. Methods The data collected in the Longitudinal Study of Chinese Breastfeeding Infants Growth and Development from birth to 4 months old in 6 well-being rural areas was used to construct the multilevel models of weight-for-age,length-for-age and BMI-for-age. Results The models showed that infant age,gender,birth weight,birth length,parity,mother age,parents' height,season,feeding patterns and the interaction effect of age and feeding patterns all had statistical significance (P<0.05). Conclusion Compared with infant general status,family and social demographic characteristics,parents' biological characteristics,perinatal these immutable factors,breastfeeding is the effective measure to promote growth of 4 months old infants in rural areas.
