【目的】掌握城市婴儿生长速率纵向发育规律,获得本地区城市婴儿生长速率正常参考值及生长曲线图,建立城市婴儿生长轨迹数据模型。【方法】按分层整群随机抽样抽取2007年7月1日—2008年7月l日出生的192个正常婴儿,监测至2009年6月31日止,其中男婴97人,女婴95人,每个婴儿分16个月(周)龄组进行体重、身长、头围测量。【结果】男女婴儿16个月(周)龄组体重、身长、头围,除体重1周组外,均随月龄增长而增长,同一月(周)龄段,均表现为男婴均值大于女婴。【结论】男女婴儿体重、身长、头围与月龄呈对数曲线经验回归方程,为制定促进儿童健康、预防和控制儿童期成人病的相关预防策略提供科学依据。提示婴儿月(周)龄越小,生长速率越快,儿童保健工作应抓早、抓小。
【Objective】 To master the longitudinal development of infant growth rate in the city, obtain the normal reference value and growth curve of the urban infant growth rate in this area and establish the urban infant growth trajectory data model. 【Method】 A total of 192 normal babies born from July 1, 2007 to July 1, 2008 were randomly selected by stratified cluster sampling and monitored until June 31, 2009, of which 97 were male and 95 were female The weight, length and head circumference of each infant in the 16-month (week) age group were measured. 【Results】 The body weight, body length and head circumference of boys and girls at 16 months (weeks) age group increased with the increase of age except 1 week body weight. The same month (week) Baby girl. 【Conclusion】 The logarithm regression equation of body weight, length, head circumference and age of the male and female babies provide a scientific basis for the development of preventive strategies to promote the health of children and prevent and control childhood adult diseases. Tips baby month (weeks) age smaller, faster growth rate, child care work should catch early, pay attention to small.
