Globally, undernutrition affects nearly half of all children aged less than 5 years. It is more prominent in low- and middle-income countries. This study aimed to identify the age-specific risk factors for different categories of undernutrition among Bangladeshi children aged less than 2 years. Data of 10,291 children aged less than 2 years were collected between October 2011 to November 2013 through the Food Security Nutritional Surveillance Project in Bangladesh. Simple logistic regression established bivariate relationships between the categories of undernutrition and the relevant risk factors. Multiple logistic regression constructed the age-specific regression models depicting the independent association and effect size of the risk factors contributing to the various categories of undernutrition among study population. Stunting was prevalent among 30.9% of the study children, whereas 9.7% were wasted and 24.9% were underweight. Being a male child, increase in age, maternal body mass index and education, and household food insecurity were the strongest predictors for all categories of undernutrition in terms of effect size. Our study shows that the different categories of childhood undernutrition have different age-specific risk factors. Maternal body mass index and household food insecurity were the common age-specific risk factors for all categories of undernutrition. We expect our findings to enhance the existing evidence base for the risk factors of undernutrition among children aged less than 2 years.
在全球范围内，营养不良影响了近一半的5岁以下儿童。在低收入和中等收入国家更为突出。本研究旨在确定孟加拉国2岁以下儿童不同类别营养不良的年龄特异性风险因素。2011年10月至2013年11月期间，通过孟加拉国粮食安全营养监测项目收集了10291名2岁以下儿童的数据。简单逻辑回归建立了营养不良类别与相关风险因素之间的双变量关系。多重逻辑回归构建了年龄特异性回归模型，描述了研究人群中导致各类营养不良的风险因素的独立关联和效应大小。发育迟缓在30.9%的研究儿童中普遍存在，而消瘦的儿童占9.7%，体重不足的儿童占24.9%。就效应大小而言，男性儿童、年龄增长、母亲体重指数和教育程度以及家庭粮食不安全是所有类别营养不良的最强预测因素。我们的研究表明，儿童期不同类别的营养不良有不同的年龄特异性风险因素。母亲体重指数和家庭粮食不安全是所有类别营养不良常见的年龄特异性风险因素。我们期望我们的研究结果能加强2岁以下儿童营养不良风险因素的现有证据基础。
