【目的】了解铜陵市婴儿体质指数(body mass index,BMI)的影响因素,为妇幼保健提供参考依据。【方法】利用在本院进行儿童保健门诊的1 308例3～4月龄婴儿初次体检的资料,计算BMI值,并对BMI的影响因素进行分析。【结果】BMI值在性别、喂养方式、出生体重以及父母亲文化程度等方面差异显著,男婴BMI均值大于女婴(P<0.05);母乳喂养的婴儿BMI均值大于人工喂养的婴儿;随着出生体重的增高,BMI均值明显增高;铜陵市3～4月龄婴儿的BMI均值高于WHO(2006版)3月婴儿的BMI均值。【结论】婴儿BMI受性别、出生体重、喂养方式及是否早产影响,应大力提倡母乳喂养。
【Objective】 To understand the influencing factors of body mass index (BMI) in Tongling City and provide reference for maternal and child health care. 【Method】 Based on the data of the first physical examination of 1 308 infants from 3 to 4 months of age undergoing child health clinic in our hospital, the BMI was calculated and the influencing factors of BMI were analyzed. 【Results】 The BMI value was significantly different in gender, feeding style, birth weight and parental education. The mean BMI of male infants was higher than that of female infants (P <0.05). The mean BMI of infants fed breast-fed infants was higher than that of infants fed artificial feeding. The mean body mass index (BMI) increased significantly with the increase of birth weight. The mean BMI of infants aged 3 to 4 months in Tongling City was higher than that of infants in March 2006 in Tongling City. 【Conclusion】 Infant BMI should be strongly promoted breastfeeding due to gender, birth weight, feeding style and whether it affects premature delivery.
