目的：了解成都市母乳喂养婴幼儿纵向生长发育现状和特点,为进行生长发育监测和营养指导提供参考依据。方法在成都市城区人群进行抽样,共224名纯母乳喂养儿进行0~36月龄生长发育监测,包括体重、身长、头围测量和喂养情况调查。结果在大多数月龄点男婴体格发育指标均高于女婴,差异均有统计学意义( t体重=1.998~5.812,t身长=2.976~4.605, t头围=2.895~6.643,均P<0.05)。9月龄后男童身长落后于2005年9市调查水平(t=-4.302~-2.208,均P<0.05)。男童在28d~36月龄体重和头围值均显著高于世界卫生组织2006年标准(t体重=1.659~7.079,t头围=2.076~6.874,均P<0.05)。除18~24月龄身长值和0月龄头围值外,女童在其他月龄体格发育值均显著高于世界卫生组织2006年标准( t体重=2.513~8.305, t身长=2.362~5.624,t头围=2.153~8.863,均P<0.05)。结论成都市母乳喂养婴幼儿男童身长值落后于国内同期调查资料,其生长发育水平仍有待进一步提高。%Objective To understand the current status and characteristics of longitudinal growth of breastfeeding children in Chengdu City, so as to provide reference for growth monitoring and nutritional guidance. Methods A total of 224 exclusively breast feeding children in Chengdu City were recruited to monitor their longitudinal growth, including weight, height, head circumference and feeding. Results The weight, height and head circumference in most of month points was higher in boys than in girls, and the differences were significant (tweight =1. 998-5. 812,theight =2. 976-4. 605, thead cirumference =2. 895-6. 643, all P<0. 05). The height of boys after 9 months of age was less than that investigated in 9 cities in 2005 [t=( -4. 302) -( -2. 208), all P<0. 05]. Compared to new growth standard issued by WHO in 2006, boy’s weight and head circumference value from 28 days to 36 months were higher in Chengdu City (tweight =1. 659 -7. 079, thead cirumference =2. 076-6. 874, both P<0. 05). At same time, girls’ anthropometric parameters were higher than the new growth standard issued by WHO in 2006 expect for the length at 18-24 months and birth head circumference ( tweight =2. 513 -8. 305,tlength =2. 362 -5. 624, thead circumference =2. 153-8. 863, all P<0. 05). Conclusion The length of breastfeeding boys in Chengdu City is inferior to that investigated at the same period, so the growth of them should be improved.
