| 摘 要： | 纵向观察595例农村婴儿和337例城市婴儿的身长、体重变化,用Count曲线分别拟合不同性别、不同喂养方式下的身长、体重均值,并作城乡间比较。结果显示,曲线拟合效果甚好,初始身长水平农村婴儿高于城市,母乳喂养儿尤甚,但生长加速度低于城市婴儿。初始体重水平城乡差异无显著性意义,但线性生长速度城市婴儿更快。主要原因为城市婴儿辅食添加状况明显优于农村。

| Abstract: | Mixed longitudinal data of length andweight growth from 595 rural and 337 urbaninfants were analysed. Count models werefitted to the means of length and weight indifferent ages, sexes and feedings separately.The curve fitting to the data was rathersatisfactory. Comparison of model parametersbetween urban and rural infants suggestedthat rural infants had a higher length levelat birth but lower accelerative growth after-wards than urban ones, which was evenmore obvious in breast-fed infants.The dif-ference in birth weight between them was notsignificant; and the urban infants had a fas-ter linear growth velocity than rural ones.These results might be caused by the factthat food supplementing in urban infants wassignificantly earlier and better than in ruralones. |
