This study examined the association between childhood conditions and cognitive function among middle-aged and older adults in China.
We analyzed data from the 2011 China Health and Retirement Longitudinal Study ( N = 11,868). Cognitive function was measured by word recall, a test of episodic memory. We examined the association between childhood conditions and cognitive function among the middle-aged (45-59 years) and the older (60 years and older) adults separately, using multilevel linear regressions.
Indicators of childhood socioeconomic status (SES) and nutrition were significantly associated with memory performance among the middle-aged and the older adults in China. Adulthood SES, education in particular, accounted for some but not all the associations. The protective effect of childhood urban residence was stronger for middle-aged women than for middle-aged men.
Childhood conditions are significantly associated with mid- to late-life cognitive function in China. The strengths of the associations may vary by gender and cohort.
本研究探讨了中国中老年人群童年状况与认知功能之间的关联。
我们分析了2011年中国健康与养老追踪调查（China Health and Retirement Longitudinal Study，CHALRS）的数据（N = 11,868）。认知功能通过单词回忆进行测量，这是一种情景记忆测试。我们分别使用多层次线性回归分析了中年（45 - 59岁）和老年（60岁及以上）人群童年状况与认知功能之间的关联。
童年社会经济地位（SES）和营养指标与中国中年和老年人群的记忆表现显著相关。成年期SES，尤其是教育程度，解释了部分但并非全部的关联。童年居住在城市对中年女性的保护作用比对中年男性更强。
在中国，童年状况与中老年期认知功能显著相关。这种关联的强度可能因性别和队列而异。
