ABSTRACT

Background:

Internet usage is an important channel for accessing health-related information. However, the effect of internet use on the health of middle-aged and older adults has not been elucidated.

Objective:

This study aimed to examine the relationship between Internet use and the health outcomes in middle-aged and older adults.

Methods:

Data were obtained from the 2018 China Health and Retirement Longitudinal Study. Physical health, mental health, and subjective health were assessed using the activities of daily living (ADL) scale, 10-item Center for Epidemiologic Studies Depression Scale (CESD-10), and three-level self-rated health, respectively. Chi-square test and rank sum test were used to explore whether Internet use was associated with the health status. A multilevel logistic regression model was used to determine this association further after controlling for the confounding factors.

Results:

The Internet usage rate among Chinese citizens aged 45 years and above was 13% in this study. The prevalence of depression and difficulty in performing ADL in the middle-aged and older adults was lower in those using the Internet than in those not using it. Additionally, good self-rated health was more prevalent among individuals using the Internet than among those not using it. After controlling for confounding factors, Internet usage was found to be negatively associated with performing ADL, depression, and self-rated health status among the middle-aged and older adults, both in the urban and rural areas.

Conclusions:

Internet usage has a positive effect on the physical and mental health of the middle-aged and older adults. The government, community, and enterprises should pay attention to the health of middle-aged and older adults, strengthen cooperation, and work together to promote ageing-friendly Internet applications. Moreover, the community should offer Internet learning and training to enhance the adaptation of the middle-aged and old individuals to the Internet.
