Early childbearing poses several potential risks to maternal and child health. This paper empirically analyses the association between teenage pregnancy and child nutritional status, maternal and child anaemia in three countries (Nigeria, India and Bangladesh) that account for the highest proportion of teenage births and/or total number of malnourished teenage mothers and children. Data were sourced from nine waves of Demographic and Health Surveys conducted in Bangladesh, India, and Nigeria from 2005-2018, covering a sample of 27,705 children from Bangladesh, 266,308 children from India and 54,719 children from Nigeria. Our outcome measures of maternal and child nutrition include (i) a composite measure of anthropometric failure for children (CIAF), (ii) maternal anaemia, (iii) childhood anaemia, and (iv) anaemia in maternal-child pairs. Using multivariate regression analysis, we examine the associations between early childbirth, child nutrition, and maternal and child anaemia, controlling for an array of household-level socioeconomic and demographic characteristics. Across all three countries, the prevalence of CIAF (childhood anthropometric failure) is significantly higher among children born to women aged below 17 at first birth. We further find that early pregnancy and childbearing are associated with significantly higher rates of severe/moderate anaemia among both mothers and children in Bangladesh and Nigeria. In the three countries studied, the proportions of teenage mothers with vulnerable socioeconomic status and suboptimal pre-conception care are relatively high, which raises the risk of maternal and child morbidity as well as mortality.
早育对母婴健康构成若干潜在风险。本文实证分析了青少年怀孕与儿童营养状况、母婴贫血之间的关联,研究对象为三个国家(尼日利亚、印度和孟加拉国),这三个国家的青少年生育比例和/或营养不良的青少年母亲及儿童总数占比最高。数据来源于2005年至2018年在孟加拉国、印度和尼日利亚进行的九轮人口与健康调查,涵盖了来自孟加拉国的27,705名儿童、来自印度的266,308名儿童和来自尼日利亚的54,719名儿童。我们衡量母婴营养的指标包括:(i)儿童人体测量失败综合指标(CIAF);(ii)孕产妇贫血;(iii)儿童期贫血;(iv)母婴贫血配对情况。我们运用多元回归分析,研究早育、儿童营养以及母婴贫血之间的关联,并控制一系列家庭层面的社会经济和人口特征。在所有这三个国家中,首次生育年龄低于17岁的女性所生育的儿童中,CIAF(儿童期人体测量失败)的患病率显著更高。我们进一步发现,在孟加拉国和尼日利亚,早孕和早育与母亲和儿童中重度/中度贫血的发生率显著较高有关。在所研究的三个国家中,社会经济地位脆弱且孕前护理欠佳的青少年母亲比例相对较高,这增加了母婴发病和死亡的风险。
