Bangladesh has a high prevalence of adolescent pregnancy, but little is known about the nutritional status and dietary practices of Bangladeshi adolescents in early pregnancy or associated factors. We used the baseline data of 1552 pregnant adolescents from a longitudinal, cluster-randomized effectiveness trial conducted in northwest Bangladesh. Forty-four percent of the adolescents were short for their age, 36% had low body mass index, 28% were anemic, 10% had iron deficiency, and 32% had vitamin A deficiency. The mean consumption of animal-source foods was 10.3 times/week. In multivariate analysis, socioeconomic status, education, and food security were generally positively associated with anthropometric indicators and dietary practices but not with iron or vitamin A status. Our findings confirm that there is a high burden of undernutrition among these Bangladeshi adolescents in early pregnancy. Understanding factors related to undernutrition can help to identify adolescent pregnant women at higher risk and provide appropriate counseling and care.
孟加拉国青少年怀孕的比例很高，但对于孟加拉国早孕青少年的营养状况、饮食习惯及相关因素却知之甚少。我们使用了在孟加拉国西北部进行的一项纵向整群随机有效性试验中1552名怀孕青少年的基线数据。44%的青少年年龄别身高偏低，36%的青少年体重指数较低，28%的青少年贫血，10%的青少年缺铁，32%的青少年维生素A缺乏。动物源食物的平均摄入量为每周10.3次。在多变量分析中，社会经济地位、教育程度和粮食安全状况总体上与人体测量指标及饮食习惯呈正相关，但与铁或维生素A状况无关。我们的研究结果证实，这些孟加拉国早孕青少年中存在着很高的营养不良负担。了解与营养不良相关的因素有助于识别高危青少年孕妇，并提供适当的咨询和护理。
