北京市323例1~<2月龄婴儿身长体重发育及喂养方式状况分析

目的了解1~<2月龄婴儿身长体重发育状况及不同喂养方式间婴儿体格发育的差异,为做好儿童保健工作提供参考。方法使用在北京市某城区医院出生、并于2017年8月-2019年7月来医院进行出生后1~<2月龄健康检查的婴儿体检资料,对婴儿的体重和身长,以及喂养方式数据进行分析。用t检验方法,分析不同性别间及不同喂养方式间婴儿体重身长的差异。结果在323名婴儿中,完全母乳喂养率为59.4%,男女婴儿完全母乳喂养率差异无统计学意义(χ^2=3.321,P=0.190)。男孩1~<2月龄时的体重身长,以及生后至1~<2月龄的体重身长增长值均明显高于女孩相应的体重身长和体重身长的增长值,差异有统计学意义(P<0.05)。男女婴儿完全母乳喂养组1~<2月龄时的体重及体重增长值均明显高于非完全母乳喂养组的体重和体重增长值,差异有统计学意义(P<0.05)。结论母乳喂养有利于婴儿体格发育,母乳喂养率尚低。应进一步加强促进母乳喂养的措施,提高母乳喂养率。

The status of weight and length growth and feeding patterns of 323 infants aged 1-2 months in Beijing

Objective To understand the weight and length growth of infant aged 1-2 months,to explore the relationship between infant physical growth and feeding pattern and to provide reference for children health care work.Methods The physical examination data of infants born in an urban area hospital of Beijing and who came to the hospital from August 2017 to July 2019 for health examination at the age of 1-2 months were used to analyze the baby’s weight,length and feeding patterns.Results Among the 323 infants,the rate of exclusive breastfeeding was 59.4%,and there was no significant difference in exclusive breastfeeding rate between male and female infants.(χ^2=3.321,P=0.190).The body weight and length of boys at the age of 1-2 months and the growth of weight and length from 1 to 2 months after birth were significantly higher than those of girls.There was statistical difference(P<0.05).The body weight and body weight growth of male and female infants from 1 to 2 months in the exclusive breastfeeding group were significantly higher than those in the non-exclusive breastfeeding group.There was statistical difference(P<0.05).Conclusions Breastfeeding is beneficial to infant’s physical development.Breastfeeding rates need to be further improved.Measures to promote breastfeeding should be further strengthened in order to improve breastfeeding rate.
