The Role of Childhood Health in Cross-national Variation in Health Gradients

描述（由申请人提供）：有一个完善的研究文献记录了健康方面巨大的、持续的和不断扩大的社会经济梯度。虽然早期的工作侧重于记录一系列广泛的健康结果和社会经济地位的多个维度的健康梯度的轮廓，但过去十年的大部分工作都集中在试图理解差异背后的因果过程。关于健康梯度原因的两个重要和相关的研究方向是：a)对不平等现象的跨国调查；b)从生命历程/发展角度研究儿童健康损害和社会经济劣势的长期影响。每一项研究都对造成健康方面社会经济不平等的社会和生命过程提供了重要见解。然而，在这些领域工作的研究人员往往很少关注其他领域。目前的项目利用来自17个国家的现有nia支持的数据，将这两种互补的方法结合起来，调查生命早期健康和社会经济劣势在国际背景下产生健康社会经济梯度方面的作用。

DESCRIPTION (provided by applicant): There is a well-established research literature documenting large, persistent, and expanding socioeconomic gradients in health. While early work focused on documenting the contours of health gradients across a wide array of health outcomes and the multiple dimensions of socioeconomic position, much of the effort over the past decade has focused on trying to understand the causal processes that underlie disparities. Two important and related, though rarely integrated, lines of research on the causes of health gradients are a) cross-national investigations of inequalities and b) life- course/developmental perspectives that have investigated the long-term impacts of childhood health insults and socioeconomic disadvantage. Each of these lines of research has provided important insights into the social and life course processes that generate socioeconomic inequalities in health. However, researchers working in each of these areas have tended to pay scant attention to the other. The current project integrates these two complementary approaches using existing NIA-supported data from 17 countries to investigate the role of early life health and socioeconomic disadvantage in generating socioeconomic gradients in health across international contexts.
