Maintaining regular physical activity is important for physical and mental health, providing benefits including protection against chronic disease. However, little is known about the causes of cessation of habitual physical activity in older people.
To identify predictors of cessation of regular physical activity in community-dwelling elderly people.
582 community-dwelling people aged 70 years and over who were living in Tokyo, Japan, were surveyed regarding physical activity levels 2 years after completing an initial survey where they indicated they took part in physical activity at least 5 days a week. Baseline demographic, health, physical functioning and psychological status measures were used as predictors of exercise cessation.
At the 2-year follow-up, 192 subjects (33%) had ceased taking part in regular physical activity. In univariate analyses, women, smokers, those who reported a fear of falling and those with a slower walking speed at baseline were significantly more likely to cease regular physical activity. Multiple logistic regression analysis identified 3 of these variables as significant and independent predictors of activity cessation: female gender (adjusted OR = 1.67, 95% CI = 1.13-2.47); smoking (OR = 2.34, 95% CI = 1.33-4.13), and slow walking speed (OR = 1.79, 95% CI = 1.07-2.98).
The study identified simple screening measures for identifying elderly people at risk of ceasing regular physical activity. Currently active older people with these factors may benefit from counseling and interventions to enable them to continue participating in regular physical activity.
保持规律的体育活动对身心健康很重要，具有预防慢性病等诸多益处。然而，对于老年人习惯性体育活动停止的原因知之甚少。
确定社区居住老年人规律体育活动停止的预测因素。
对居住在日本东京的582名70岁及以上的社区居民进行了调查，这些人在完成初始调查2年后被问及体育活动水平，初始调查中他们表示每周至少进行5天体育活动。基线人口统计学、健康、身体功能和心理状态指标被用作运动停止的预测因素。
在2年随访时，192名受试者（33%）停止了规律体育活动。单因素分析显示，女性、吸烟者、报告有跌倒恐惧的人以及基线时步行速度较慢的人更有可能停止规律体育活动。多因素逻辑回归分析确定其中3个变量为活动停止的显著且独立预测因素：女性（调整后的比值比=1.67，95%置信区间=1.13-2.47）；吸烟（比值比=2.34，95%置信区间=1.33-4.13），以及步行速度慢（比值比=1.79，95%置信区间=1.07-2.98）。
该研究确定了用于识别有停止规律体育活动风险的老年人的简单筛查措施。目前具有这些因素的活跃老年人可能会从咨询和干预中受益，从而使他们能够继续参与规律体育活动。
