■社会隔离与死亡风险增加有关。另一方面,一些老年人更喜欢独处。此外,隔离的预测因素在干预措施中大多没有变化.因此,了解如何单独预防负面健康结果将是有益的。降低死亡风险的因素之一是定期运动。然而,到目前为止,据我们所知,还没有研究研究定期锻炼是否能降低社会孤立个体的死亡率。这项研究旨在确定社会隔离和定期运动相结合对社区居住老年人死亡率的影响。
■这项前瞻性队列研究是对居住在伊塔巴什区的社区居住老年人进行的更大的Otassha研究的一部分,东京,日本。2012年10月,835人(男性=350,女性=485;平均年龄73.1岁)完成了全面的基线健康调查。如果个人与他人的互动频率平均每周少于一次,则他们被认为是社会孤立的。定期锻炼被定义为每周至少进行两次锻炼。参与者被分配到以下四组之一:(1)不孤立与定期锻炼,(2)未经定期锻炼,不孤立,(3)与经常锻炼隔离,(4)不经常锻炼而孤立。从病房办公室数据库获得全因死亡率信息。后续行动一直持续到2020年11月1日。进行Cox比例回归分析。
■对735名参与者(男性=303,女性=432;平均年龄72.9岁)的完整数据集进行了最终分析。共132人(18.0%),426(58.0%),27(3.7%),150名(20.4%)参与者分别被分配到第1,2,3和4组.第1、2、3和4组的死亡率为6.1%,9.2%,7.4%,和19.3%,分别。与第1组相比,未进行定期运动的孤立个体的死亡率[调整后的风险比(aHR),2.48;95%置信区间(CI),1.12-5.52].然而,在进行定期锻炼的孤立个体中没有发现显著的关联(AHR,1.25;95%CI,0.26-5.91)。
■定期运动与死亡风险的降低有关,不管社会隔离状况如何。因此,我们的研究结果表明,鼓励孤立的老年人定期运动可能会减少他们的负面健康结果.
UNASSIGNED: Social isolation is associated with increased mortality risk. On the other hand, some older adults prefer to be alone. Additionally, predictors of isolation are mostly unchanged across interventions. Therefore, knowledge of how to prevent negative health outcomes in isolation would be beneficial. One of the factors that reduces the risk of mortality is regular exercise. However, to date, no studies to our knowledge have examined whether regular exercise reduces mortality among socially isolated individuals. This study aimed to determine the effects of the combination of social isolation and regular exercise on mortality among community-dwelling older adults.
UNASSIGNED: This prospective cohort study was part of the larger Otassha Study of community-dwelling older adults living in Itabashi Ward,
Tokyo, Japan. In October 2012, 835 individuals (males = 350, females = 485; mean age 73.1 years) completed a comprehensive baseline health survey. Individuals were considered socially isolated if their frequency of interactions with others averaged less than once per week. Regular exercise was defined as exercise performed at least twice a week. The participants were assigned to one of the following four groups: (1) not isolated with regular exercise, (2) not isolated without regular exercise, (3) isolated with regular exercise, and (4) isolated without regular exercise. All-cause mortality information was obtained from the ward office database. Follow-ups were conducted until 1 November 2020. A Cox proportional regression analysis was performed.
UNASSIGNED: A final analysis was performed on a complete dataset of 735 participants (males = 303, females = 432; mean age 72.9 years). A total of 132 (18.0%), 426 (58.0%), 27 (3.7%), and 150 (20.4%) participants were assigned to groups 1, 2, 3, and 4, respectively. The mortality rates in groups 1, 2, 3, and 4 were 6.1%, 9.2%, 7.4%, and 19.3%, respectively. Compared with group 1, isolated individuals who did not perform regular exercise had a significantly higher mortality rate [adjusted hazard ratio (aHR), 2.48; 95% confidence interval (CI), 1.12-5.52]. However, no significant association was noted in isolated individuals who performed regular exercise (aHR, 1.25; 95% CI, 0.26-5.91).
UNASSIGNED: Regular exercise was associated with a decrease in mortality risk, regardless of social isolation status. Thus, our results indicate that encouraging isolated older adults to exercise regularly may reduce their negative health outcomes.
