The factors associated with cognitive decline among older adults include physical activity and fruit and vegetable intake. However, the long-term effects of concomitant physical activity and fruit and vegetable intake are unknown. This 16-year longitudinal study explored the joint effect of mitigating cognitive decline in a cohort of older Taiwanese individuals. Five population-based surveys (Taiwan Longitudinal Survey on Aging [1999-2015]) involving 4440 respondents over 53 years old in 1999 were conducted. Cognitive function was assessed using the Short Portable Mental Status Questionnaire (SPMSQ). The demographic, socioeconomic, health-related, behavioral, and disease status covariates were adjusted in the regression analysis. Trends in cognitive decline were observed over 16 years. The risk of cognitive decline decreased by 63% when high physical activity and high fruit and vegetable intake were combined (odds ratio 0.37; 95% confidence interval 0.23-0.59), indicating a potential combined effect of physical activity and fruit and vegetable intake on mitigating cognitive decline. These personal actions are safe, effective, and economical approaches to health promotion and disease prevention.
与老年人认知能力下降相关的因素包括身体活动和水果与蔬菜摄入。然而，身体活动和水果与蔬菜摄入同时存在的长期影响尚不清楚。本 16 年纵向研究旨在探讨身体活动和水果与蔬菜摄入对台湾老年人群认知能力下降的综合影响。研究纳入了五次基于人群的调查（1999-2015 年台湾老龄化纵向研究），共涉及 1999 年超过 53 岁的 4440 名受访者。使用简短便携式精神状态问卷（SPMSQ）评估认知功能。回归分析中调整了人口统计学、社会经济、健康相关、行为和疾病状态等协变量。研究观察到认知能力下降趋势持续了 16 年。当高身体活动和高水果与蔬菜摄入相结合时，认知能力下降的风险降低了 63%（优势比 0.37；95%置信区间 0.23-0.59），表明身体活动和水果与蔬菜摄入对认知能力下降有潜在的综合影响。这些个人行为是促进健康和预防疾病的安全、有效且经济的方法。
