: Previous research on cognitive impairment and health behaviors has focused largely on how health behaviors affect cognition; rarely has it examined whether cognitive impairment affects health behaviors. The purpose of this study was to examine the impact of cognitive impairment on engagement in health behaviors among older adults. The study sample included 19,644 adults aged 50 or older from the Health and Retirement Study 1995-2012 surveys. We used mixed-effects logistic regression to analyze the influence of cognitive impairment, measured using the Telephone Interview for Cognitive Status, on the engagement of health behaviors including physical activity, smoking, and drinking. Cognitive impairment without dementia [CIND] (OR = .84, 95% CI = .80-.89) and dementia (OR = .68, 95% CI = .61-.75) were associated with a lower likelihood of engaging in regular vigorous physical activity during longitudinal follow-up, after adjusting for covariates. CIND or dementia was not significantly associated with the likelihood of smoking or alcohol consumption. CIND and dementia are risk factors for physical inactivity among older adults. Promotion of regular physical activity should be an essential component of health promotion programs for persons with cognitive impairment.
先前有关认知障碍和健康行为的研究主要集中在健康行为如何影响认知；很少有研究探讨认知障碍是否会影响健康行为。本研究旨在探讨认知障碍对老年人参与健康行为的影响。研究样本包括来自健康与退休研究（1995-2012 年调查）的 19644 名 50 岁或以上的成年人。我们使用混合效应逻辑回归分析了使用电话访谈认知状态测量的认知障碍对健康行为（包括身体活动、吸烟和饮酒）参与的影响。无痴呆认知障碍[CIND]（OR=.84，95%CI=.80-.89）和痴呆（OR=.68，95%CI=.61-.75）与纵向随访期间经常进行剧烈身体活动的可能性降低相关，调整了协变量。CIND 或痴呆与吸烟或饮酒的可能性没有显著关联。CIND 和痴呆是老年人身体活动不足的危险因素。促进有认知障碍的人定期进行身体活动应成为健康促进计划的重要组成部分。
