来京务工人员母乳喂养婴儿0—12月龄生长发育指标的随访分析

Longitudinal Growth Velocity Monitoring of 0—12 Months Breastfeeding Infants in Beijing's Migrant Families

目的:了解来京务工家庭纯母乳喂养婴儿体格生长发育情况,为开展个体及群体生长发育监测和喂养指导提供参考依据。方法:对中日友好医院预防保健科及朝阳区妇幼保健院辖区内91名来京务工家庭母乳喂养的婴儿进行0—12月龄体格生长发育监测,包括体重、身长、头围的测量和喂养情况调查,共完成16次随访。结果:纯母乳喂养婴儿0—12月龄生长发育最快时期为生后3月龄内,增速分别为体重2月龄>1月龄>3月龄,身长和头围1月龄>2月龄>3月龄,与世界卫生组织标准一致。男婴生后5个月内体重及身长增值与WHO标准持平,之后略低于WHO标准;女婴8个月内体重及身长增值与WHO标准持平,之后略低于WHO标准。男、女婴12个月内体重增值普遍低于6城市婴儿资料;女婴8个月内身长增值与城市女婴资料基本持平,8个月后低于城市女婴资料,男婴身长增值则普遍低于城市男婴资料。结论:来京务工母亲的母乳喂养婴儿生长发育轨迹与世界卫生组织2006年的标准一致,但婴儿体格发育增值不及同期中国6城市母乳喂养婴儿的体格发育。

[Objective] To obtain the physical increment values of exclusively breastfeeding infants in Beijing＇s migrant families and to provide references for growth monitoring and nutritional evaluation,and carry out individual and population growth monitoring and feeding guidance reference.[Method] According to the WHO Growth Monitoring Project issued in 2006,totally 91 exclusively breastfeeding infants aged 0-12 months old were monitored,including weight,height,head circumference and feeding.The monitoring frequency was 16 times in total.[Result] Exclusively breastfeeding infants＇ weight at 3 months was doubled than birth weight,tripled at 12 months in migrant families.The weight increment was most at 2 months,followed by 1 months,then by 3 months,and the increment of height and head circumference was most at 1 month,followed by 2 months,then by 3 months.The growth tendency was consistent with the standard of WHO.Compared with data of survey in six capital cities,the increment values of weight were lower in boys and girls before 12 months,and the increment values of height were lower in boys before 12 months.[Conclusion] The growth trajectory and development status of breastfeeding infants in Beijing＇s migrant families were in accordance with the standard issued in 2006 by WHO,while physical increment values were less than average levels of six capital cities in China.
