背景:随着所有年龄段的互联网使用趋势的增加,互联网使用是否可以预防中老年人的虚弱仍不清楚。
方法:五个队列,包括健康与退休研究(HRS),中国健康与退休纵向研究(CHARLS),健康调查,欧洲的老龄化和退休(SHARE),英国衰老纵向研究(ELSA),墨西哥健康与老龄化研究(MHAS)在这项研究中使用。互联网使用,社会孤立,使用类似的问题评估虚弱状态。广义估计方程模型,随机效应荟萃分析,COX回归,并利用调解分析。
结果:在多队列研究中,共有155,695名参与者被纳入主要分析.互联网使用的比例因国家而异,从中国的5.56%(CHARLS)到丹麦的83.46%(份额)不等。根据广义估计方程模型和荟萃分析,互联网使用与脆弱成反比,合并OR(95CIs)为0.72(0.67,0.79)。COX回归还显示,使用互联网的参与者的虚弱发生率风险较低。此外,这种关联部分是由社会隔离介导的,在65岁及以上的参与者中略有明显,男性,不为付款而工作,没有结婚或伴侣,不吸烟,饮酒,而不是与孩子共同居住。
结论:我们的研究结果强调了使用互联网在预防虚弱方面的重要作用,并建议更多参与社会交往和活动,以避免中老年人的社会隔离。
BACKGROUND: With increasing trend of internet use in all age groups, whether internet use can prevent frailty in middle-aged and older adults remains unclear.
METHODS: Five cohorts, including Health and Retirement Study (HRS), China Health and Retirement Longitudinal Study (CHARLS), the Survey of Health, Ageing and Retirement in Europe (SHARE), English Longitudinal Study of Aging (ELSA), and Mexican Health and Aging Study (MHAS), were used in this study. Internet use, social isolation, and frailty status was assessed using similar questions. The Generalized estimating equations models, random effects meta-analysis, COX regression, and mediation analysis were utilized.
RESULTS: In the
multicohort study, a total of 155,695 participants were included in main analysis. The proportion of internet use was varied across countries, ranging from 5.56% in China (CHARLS) to 83.46% in Denmark (SHARE). According to the generalized estimating equations models and meta-analysis, internet use was inversely associated with frailty, with the pooled ORs (95%CIs) of 0.72 (0.67,0.79). The COX regression also showed that participants with internet use had a lower risk of frailty incidence. Additionally, the association was partially mediated by social isolation and slightly pronounced in participants aged 65 and over, male, not working for payment, not married or partnered, not smoking, drinking, and not co-residence with children.
CONCLUSIONS: Our findings highlight the important role of internet use in preventing frailty and recommend more engagements in social communication and activities to avoid social isolation among middle-aged and older adults.
