This study investigated the effect of family planning on the levels of women's anaemia and child undernutrition at the aggregate level using the compiled databases of the World Bank, UNICEF and the Economist Intelligence Unit. Correlation scatter matrix plots and multivariate OLS regression models were employed to assess the effect of family planning on women's anaemia and child nutritional status across countries. At the aggregate level, the bivariate correlation estimates found that the Contraceptive Prevalence Rate (CPR) was negatively associated with women's anaemia (r=-0.62, p<0.01), child underweight (r=-0.57, p<0.01) and child stunting (r=-0.63, p<0.01). The results of the OLS regression showed that the independent effect of CPR on women's anaemia (β=-0.35, p<0.01), child underweight (β=-0.13, p<0.01) and child stunting (β=-0.18, p<0.05) was negative, even after controlling for child marriage, female literacy, per capita GDP, poverty ratio, health expenditure and food security. The synthesis of these findings with the existing literature based on micro-data suggests pathways through which family planning influences the nutritional status of women and children. Family planning helps in avoiding shorter birth intervals, unintended pregnancy and unsafe abortion, which would otherwise result in nutrient depletion among mothers and further increase the risk of undernutrition in their children.
本研究利用世界银行、联合国儿童基金会和经济学人智库汇编的数据库,在总体层面调查了计划生育对妇女贫血水平和儿童营养不良的影响。采用相关散点矩阵图和多元OLS回归模型,评估各国计划生育对妇女贫血和儿童营养状况的影响。在总体层面,双变量相关估计发现,避孕普及率(CPR)与妇女贫血(r=-0.62,p<0.01)、儿童体重不足(r=-0.57,p<0.01)和儿童发育迟缓(r=-0.63,p<0.01)呈负相关。OLS回归结果表明,即使在控制了童婚、女性识字率、人均GDP、贫困率、卫生支出和粮食安全之后,CPR对妇女贫血(β=-0.35,p<0.01)、儿童体重不足(β=-0.13,p<0.01)和儿童发育迟缓(β=-0.18,p<0.05)的独立影响仍为负。将这些研究结果与基于微观数据的现有文献相结合,揭示了计划生育影响妇女和儿童营养状况的途径。计划生育有助于避免生育间隔过短、意外怀孕和不安全堕胎,否则这些情况会导致母亲营养耗尽,并进一步增加其子女营养不良的风险。
