Recent studies examining the relationship between family income and child health in the UK have produced mixed findings. We re-examine the income gradient in child general health and its evolution with child age in this country, using a very large sample of British children. We find that there is no correlation between income and child general health at ages 0-1, that the gradient emerges around age 2 and is constant from age 2 to age 17. In addition, we show that the gradient remains large and significant when we reduce the endogeneity of income. Furthermore, our results indicate that the gradient in general health reflects a greater prevalence of chronic conditions among low-income children and a greater severity of these conditions. Taken together, these findings suggest that income does matter for child health in the UK and may play a role in the intergenerational transmission of socioeconomic status.
最近的研究考察了英国家庭收入与儿童健康之间的关系,得出了混合的结果。我们使用大量英国儿童的样本,重新检验了该国儿童一般健康状况的收入梯度及其随儿童年龄的变化。我们发现,0-1 岁儿童的收入与一般健康状况之间没有相关性,收入梯度在 2 岁左右出现,并从 2 岁到 17 岁保持不变。此外,当我们降低收入的内生性时,我们还表明,当我们降低收入的内生性时,梯度仍然很大且显著。此外,我们的结果表明,一般健康状况的梯度反映了低收入儿童中慢性疾病的患病率更高,这些疾病的严重程度也更高。综上所述,这些发现表明,在英国,收入确实对儿童健康很重要,并且可能在社会经济地位的代际传递中发挥作用。
