The present study had three major aims: 1) To identify sub-groups of adults with differing combinations of childhood maltreatment exposures, 2) to understand the association of childhood maltreatment sub-group membership with subjective sleep quality in midlife, and 3) to assess poor sleep quality in midlife as a mechanism between childhood maltreatment sub-group membership and physical functional limitations in late adulthood. Data come from the Biomarker project of the Midlife Development in the United States study ( = 1251). The Pittsburgh Sleep Quality Index (Buysse et al., 1989) was used to assess sleep quality in midlife. Functional limitations in late adulthood were measured using a version of the SF-36 (Brazier et al., 1992). Two vulnerable childhood maltreatment sub-groups emerged (Physical and Emotional Maltreatment Sub-group, = 49, and Sexual Abuse Sub-group, = 105) and a normative sub-group ( = 1087; low exposure to childhood maltreatment). Poor sleep quality in midlife mediated the association between both maltreatment sub-groups and functional limitations in late adulthood. Results highlight the role of sleep in linking childhood maltreatment with functional impairments in adulthood and offer a potential target for interventions to improve quality of life in older adults.
1）确定具有不同童年期虐待暴露组合的成年人亚组；2）了解童年期虐待亚组归属与中年主观睡眠质量之间的关系；3）评估中年睡眠质量差是否是童年期虐待亚组归属与晚年身体功能障碍之间的中介机制。数据来自美国中年发展生物标志物研究项目（n=1251）。采用匹兹堡睡眠质量指数（Buysse 等人，1989）评估中年睡眠质量。晚年身体功能障碍采用 SF-36 （Brazier 等人，1992）的一个版本进行测量。两个易受伤害的童年期虐待亚组（身体和情感虐待亚组，n=49，性虐待亚组，n=105）和一个正常亚组（n=1087；童年期虐待低暴露）。中年睡眠质量差在两个虐待亚组与晚年身体功能障碍之间的关联中起中介作用。结果突出了睡眠在将童年期虐待与成年后的功能障碍联系起来的作用，并为改善老年人生活质量的干预措施提供了一个潜在目标。
