目的本研究的目的是调查福尔斯，包括福尔斯在结冰的道路上，和身体活动之间的关系，在日本寒冷，多雪地区的老年人生活。方法参与者是2016年日本老年学评估研究的受试者，他们同意在2017/18年冬季进行北海道额外访问调查，并居住在日本寒冷的多雪地区。该分析包括461名参与者（平均年龄74.7岁;标准差2.8岁; 46.5%男性）。调查了社会人口学特征、通过加速度计测量的体力活动（中等至剧烈强度体力活动[MVPA]和轻强度体力活动的分钟/天，以及步行步数/天）、认知功能、抑郁、视力障碍和卒中史。Poisson回归分析用于阐明福尔斯患病率与体力活动之间的关系。结果在有跌倒地点的人群中，86例（69.9%）跌倒在结冰的道路上，24例（19.5%）跌倒在未结冰的道路上，13例（10.6%）跌倒在室内。MVPA（校正的患病率[aPR]三分位数[T] 3 vs T1，1.73; 95%置信区间[CI]，1.04-2.87）与所有福尔斯之间存在显著正相关。当仅限于在冰冻道路上的福尔斯跌倒时，较高的MVPA水平和步行步数与在冰冻道路上的福尔斯跌倒相关（MVPA，aPR T3 vs T1，2.16; 95%CI，1.19-3.94;步行步数，aPR T3 vs T1，2.49; 95%CI 1.33-4.68）。结论福尔斯的风险，特别是在结冰的道路上，增加活跃的老年人生活在寒冷，多雪的地区，环境因素应考虑当确定预防策略.Key summary pointsAim调查之间的关联福尔斯和加速计测量的身体活动的老年人生活在寒冷，多雪的地区在日本。结果：较高的中到高强度的体力活动水平和步行步骤与福尔斯在结冰的道路上。信息生活在寒冷、多雪地区的活跃老年人中，福尔斯跌倒的风险增加，尤其是在结冰的道路上，在确定预防策略时应考虑环境因素。
Purpose The aim of the present study was to investigate the association between falls, including falls on frozen roads, and physical activity among older people living in cold, snowy regions in Japan. Methods Participants were subjects of the Japan Gerontological Evaluation Study 2016 who had agreed to the Hokkaido additional visit survey in winter 2017/18 and lived in cold, snowy regions in Japan. The analysis included 461 participants (mean age 74.7 years; standard deviation 2.8 years; 46.5% male). Sociodemographic characteristics, physical activity (min/day of moderate-to-vigorous intensity physical activity [MVPA] and light intensity physical activity, and walking steps/day) measured by accelerometer, cognitive function, depression, visual impairment, and history of stroke were surveyed. Poisson regression analyses were performed to clarify the association between prevalence of falls and physical activity. Results Of those who reported a fall with location, 86 (69.9%) fell on frozen roads, 24 (19.5%) fell on unfrozen roads and 13 (10.6%) fell indoors. There were significant positive associations between MVPA (adjusted prevalence ratio [aPR] Tertile [T] 3 vs T1, 1.73; 95% confidence interval [CI], 1.04-2.87) and all falls. When limited to falls on frozen roads, higher MVPA levels and walking steps were associated with falls on frozen roads (MVPA, aPR T3 vs T1, 2.16; 95% CI, 1.19-3.94; walking steps, aPR T3 vs T1, 2.49; 95%CI 1.33-4.68). Conclusion The risk of falls, especially on frozen roads, increased among active older people living in cold, snowy regions, and environmental factors should be considered when determining prevention strategies.Key summary pointsAim To investigate the association between falls and accelerometer measured physical activity among older people living in cold, snowy regions in Japan.
