Previous growth studies of Peruvian children have featured high stunting rates and limited information about body composition.
We aimed to characterize anthropometric measures of Peruvian infants 0 to 12 months of age in relation to the international growth references and biological, environmental, and socioeconomic factors.
Infants (n = 232) were followed longitudinally from birth through 12 months of age from a prenatal zinc supplementation trial conducted in Lima, Peru, between 1995 and 1997. Anthropometric measures of growth and body composition were obtained at enrollment from mothers and monthly through 1 year of age from infants. Weekly morbidity and dietary intake surveillance was carried out during the second half of infancy.
The prevalence rates of stunting, underweight, and wasting did not exceed 4% based on the World Health Organization growth references. Infants of mothers from high-altitude regions had larger chest circumference (p = .006) and greater length (p = .06) by 12 months. Significant predictors of growth and body composition throughout infancy were age, sex, anthropometric measurements at birth, breastfeeding, maternal anthropometric measurements, primiparity, prevalence of diarrhea among children, and the altitude of the region of maternal origin. No associations were found for maternal education, asset ownership, or sanitation and hygiene factors.
Peruvian infants in this urban setting had lower rates of stunting than expected. Proximal and familial conditions influenced growth throughout infancy.
先前对秘鲁儿童的生长研究显示发育迟缓率很高，且有关身体成分的信息有限。
我们旨在描述秘鲁0至12个月大婴儿的人体测量指标，并将其与国际生长参考标准以及生物学、环境和社会经济因素相关联。
1995年至1997年在秘鲁利马进行的一项产前补锌试验中，对232名婴儿从出生到12个月大进行了纵向跟踪。在入组时从母亲那里获取生长和身体成分的人体测量指标，在婴儿1岁之前每月从婴儿那里获取一次。在婴儿期后半段进行每周发病率和饮食摄入监测。
根据世界卫生组织生长参考标准，发育迟缓、体重不足和消瘦的患病率不超过4%。到12个月大时，来自高海拔地区母亲的婴儿胸围更大（p = 0.006），身长更长（p = 0.06）。婴儿期整个生长和身体成分的显著预测因素包括年龄、性别、出生时的人体测量指标、母乳喂养、母亲的人体测量指标、初产情况、儿童腹泻患病率以及母亲原籍地区的海拔高度。未发现与母亲教育程度、资产拥有情况或卫生与清洁因素有关联。
在这种城市环境中的秘鲁婴儿发育迟缓率低于预期。近期和家庭状况影响婴儿期的整个生长过程。
