【摘要】 目的:了解婴儿期体格生长速率变化的规律,制定相应的婴儿期体格生长速率标准值,指导家长准确地评价婴儿生长发育状况。方法:对389名正常足月儿分别在初生、3月龄、6月龄、9月龄、12月龄测量其体重、身长,按性别、喂养方式、出生体重分组并进行分析。结果:婴儿期不同阶段的体重、身长增长速率存在非常显著性差异(P<0.001),头三个月最快,以后呈迅速递减趋势。男婴体重、身长增长速率在出生后头三个月明显快于女婴,此后三个月龄阶段无显著性差异;不同喂养方式婴儿各月龄阶段体重、身长增长速率差异无统计学意义;不同出生体重婴儿各月龄阶段体重、身长增长速率差异无统计学意义。结论:0～3个月婴儿体格增长最快,肥胖检出率迅速上升;喂养方式和出生体重对婴儿期生长速率无明显影响,且4～12个月期间生长速率的性别差异消失。更多还原

【Abstract】 Objective:To understand the change rule of physical growth of term infants in babyhood,establish standard value of growth rate of term infants and direct parents to evaluate the status of physical growth of term infants.Methods:The body height and body weight of 389 term infants were detected at birth,the third,sixth,ninth and twelfth months,then the infants were grouped according to gender, feeding patterns and body height.Results:There was significant difference in growth rates of body weight and body height between different growth stages(P<0.001),the growth rates in the first three months were the fastest,then presented a decline trend.In the first three months,the growth rates of body weight and body height of boys were significantly faster than those of girls,but there was no difference in the 4～6 months after birth.There was no difference in growth rates of body weight and body height between different feeding patterns and different body weights.Conclusion:The growth rate of infants aged 0～3 months old is the fastest,and the incidence of obesity increases rapidly; feeding patterns and body weight dont affect growth rate of term infants in babyhood,gender difference of growth rate during 4～12 months disappears.更多还原
