现有证据表明，社会孤立与健康状况不佳有关。为了研究社会隔离的死亡风险差异，以及社会隔离的社会经济相关性，我们分析了日本和英国的大规模队列研究。参与者来自日本老年学评估研究（JAGES）和英国老龄化纵向研究（艾尔莎）。我们分析了15313名JAGES参与者和5124名艾尔莎应答者的10年死亡率。社会隔离是通过两个尺度来衡量的，即，对与亲密关系人接触的频率进行评分，并对社会隔离风险进行综合衡量。我们计算了人群归因分数，并使用多重插补的考克斯回归模型来估计社会隔离导致死亡的风险比（HR）。在JAGES和艾尔莎中，接触频率低于每月一次的比例分别为8.5%和1.3%。在这两个国家，男性、老年人、自评健康状况不佳的人和未婚者与社会孤立显著相关。这两个量表都显示，老年人的社会隔离有显着更高的过早死亡的风险（JAGES中与他人接触频率较低：风险比[HR] = 1.18，95%置信区间[CI]：1.05-1.33，艾尔莎中：HR = 1.27，95% CI：0.85-1.89; JAGES中隔离风险评分较高：HR = 1.30，95% CI：1.12-1.50，艾尔莎：HR = 2.05，95% CI：1.52-2.73）。人口归因分数显示，日本每年约有18000例过早死亡归因于与近亲接触较少，而英国约为1800例。与英国相比，日本老年人社会隔离对健康的负面影响更大。Geriatr Gerontol Int 2021; 21：209-214.
Existing evidence links social isolation with poor health. To examine differences in the mortality risk by social isolation, and in socio‐economic correlates of social isolation, we analyzed large‐scale cohort studies in Japan and England. Participants were drawn from the Japan Gerontological Evaluation Study (JAGES) and the English Longitudinal Study of Ageing (ELSA). We analyzed the 10‐year mortality among 15 313 JAGES participants and 5124 ELSA respondents. Social isolation was measured by two scales, i.e., scoring the frequency of contact with close ties, and a composite measurement of social isolation risk. We calculated the population attributable fraction, and Cox regression models with multiple imputations were used to estimate hazard ratios (HRs) for mortality due to social isolation. The proportion of those with contact frequency of less than once a month was 8.5% in JAGES and 1.3% in ELSA. Males, older people, those with poor self‐rated health, and unmarried people were significantly associated with social isolation in both countries. Both scales showed that social isolation among older adults had a remarkably higher risk for premature death (less frequent contact with others in JAGES: hazard ratio [HR] = 1.18, 95% confidence interval [CI]: 1.05–1.33, in ELSA: HR = 1.27, 95% CI: 0.85–1.89; and high isolation risk score in JAGES: HR = 1.30, 95% CI: 1.12–1.50, in ELSA: HR = 2.05, 95% CI: 1.52–2.73). The population attributable fraction showed less frequent contact with close ties was attributed to about 18 000 premature deaths annually in Japan, in contrast with about 1800 in England. Negative health impacts of social isolation were higher among older Japanese compared with those in England. Geriatr Gerontol Int 2021; 21: 209–214.
