背景：良好的婴儿生长对未来的健康很重要。评估生长在世界各地的儿科护理中很常见，无论是在人群还是个体水平。有几个研究出生体重和增长的研究比较城市和农村社区在越南。第一个目的是描述和比较出生体重分布和身体发育（体重和长度）的儿童在他们的第一年在一个农村和一个城市地区的河内越南。第二个目的是研究的人体测量结果和经济和教育situation.Methods指标之间的关联：共1,466名儿童，出生于2009年3月1日至2010年6月，每月从出生到12个月的年龄在两个健康和人口监测点，一个农村和一个城市。总共进行了14，199次体重和长度测量。单独记录出生体重。有关个人和家庭的人口状况、教育、职业和经济状况的资料来自家庭调查。结果：城市新生儿出生体重高于农村新生儿，体重增长快于农村新生儿。城市男孩和女孩的平均出生体重分别为3 298克和3 203克，而农村儿童的平均出生体重分别为3 105克和3 057克。出生90天后，城市男孩的体重估计比农村男孩重4.1%。在360天时，该差异增加至7.2%。女孩的相应差异为3.4%和10.5%。长度的差异相对较小。出生体重和生长的统计学显着和正相关的经济条件和母亲的教育。结论：出生体重较低，生长，体重和长度，相当慢，在农村地区，男孩以及女孩。研究结果支持了这样一种假设，即母亲教育和经济条件的巨大差异导致母亲和儿童营养不良，从而导致出生体重和生长不良。
Background: Good infant growth is important for future health. Assessing growth is common in pediatric care all over the world, both at the population and individual level. There are few studies of birth weight and growth studies comparing urban and rural communities in Vietnam. The first aim is to describe and compare the birth weight distributions and physical growth (weight and length) of children during their first year in one rural and one urban area of Hanoi Vietnam. The second aim is to study associations between the anthropometric outcomes and indicators of the economic and educational situations.Methods: Totally 1,466 children, born from 1st March, 2009 to June 2010, were followed monthly from birth to 12 months of age in two Health and Demographic Surveillance Sites; one rural and one urban. In all, 14,199 measurements each of weight and length were made. Birth weight was recorded separately. Information about demographic conditions, education, occupation and economic conditions of persons and households was obtained from household surveys. Fractional Polynomial models and standard statistical methods were used for description and analysis.Results: Urban infants have higher birth weight and gain weight faster than rural infants. The mean birth weight for urban boys and girls were 3,298 grams and 3,203 grams as compared to 3,105 grams and 3,057 grams for rural children. At 90 days, the urban boys were estimated to be 4.1% heavier than rural boys. This difference increased to 7.2% at 360 days. The corresponding difference for girls was 3.4% and 10.5%. The differences for length were comparatively smaller. Both birth weight and growth were statistically significantly and positively associated with economic conditions and mother education.Conclusion: Birth weight was lower and the growth, weight and length, considerably slower in the rural area, for boys as well as for girls. The results support the hypothesis that the rather drastic differences in maternal education and economic conditions lead to poor nutrition for mothers and children in turn causing inferior birth weight and growth.
