Being able to use the Internet is becoming increasingly important in today's digitized society. Evidence suggests that older adults are at risk of being left behind by technological developments. We examined Internet adoption in older adults in relation to sociodemographic, health, cognitive, social, and personality factors. We used data from the Health and Retirement Study (n = 5,949; 61 percent women; age: M = 72 years, standard deviation [SD] = 7; range = 50–105). Internet use was examined over an 8-year period. Predictors were assessed at baseline. We used a Cox proportional hazards model to examine how predictors were related to Internet adoption during the study period. Overall, 1,296 out of 5,949 participants (22 percent) reported starting to use the Internet during the study period. Our findings revealed that younger age, higher education, higher income, living with a partner, and better cognitive performance were associated with a higher likelihood of Internet adoption, whereas being Black was associated with a lower likelihood. Openness was associated with a higher likelihood of Internet adoption over the study period. Our findings add to the literature on the role of sociodemographic, cognitive, and health factors in older adults' Internet use. In addition, we show that personality also predicts older adults' Internet use.

老年人采用互联网：健康与退休研究的结果

在当今的数字化社会中，能够使用Internet变得越来越重要。有证据表明，老年人有被技术发展抛在后面的风险。我们研究了老年人在社会人口统计学，健康，认知，社会和人格因素方面的互联网采用情况。我们使用了健康与退休研究的数据（n  = 5,949； 61％的女性；年龄：M  = 72岁，标准差[ SD] = 7; 范围= 50–105）。在8年的时间内检查了互联网的使用情况。预测指标在基线进行评估。在研究期间，我们使用Cox比例风险模型检查了预测因素与互联网采用的关系。总体而言，在5949名参与者中，有1,296名（占22％）报告说在研究期间开始使用互联网。我们的研究结果表明，年龄越小，受教育程度越高，收入越高，与伴侣生活在一起以及认知能力越好，则采用互联网的可能性就越高，而黑人则越可能被互联网采用。在研究期间，开放性与采用互联网的可能性更高有关。我们的发现增加了关于社会人口统计学，认知和健康因素在老年人互联网使用中的作用的文献。此外，
