Data from three rounds of nationally representative health surveys in India (1992/93, 1998/99 and 2005/06) are used to assess the impact of selective mortality on children's anthropometrics. The nutritional status of the child population was simulated under the counterfactual scenario that all children who died in the first three years of life were alive at the time of measurement. The simulations demonstrate that the difference in anthropometrics due to selective mortality would be large only if there were very large differences in anthropometrics between the children who died and those who survived. Differences of this size are not substantiated by the research on the degree of association between mortality and malnutrition. The study shows that although mortality risk is higher among malnourished children, selective mortality has only a minor impact on the measured nutritional status of children stratified by gender.
利用印度三轮全国代表性健康调查(1992/93 年、1998/99 年和 2005/06 年)的数据,评估选择性死亡对儿童人体测量指标的影响。在假设所有在生命头三年死亡的儿童在测量时都存活的反事实情景下,模拟儿童人群的营养状况。模拟结果表明,只有在死亡儿童和存活儿童之间的人体测量指标存在非常大的差异时,选择性死亡对人体测量指标的差异才会很大。而这种规模的差异在关于死亡率与营养不良之间关联程度的研究中并没有得到证实。研究表明,尽管营养不良的儿童死亡风险更高,但选择性死亡对按性别分层的儿童的营养状况的测量影响很小。
