Middle-aged and older adults should have the ability to obtain, understand, appraise, and use health information on social media platforms. Better health literacy may enhance individuals' health behavior and quality of life. The purpose of the study was to examine the relationship between social media health literacy, health behavior, and quality of life among middle-aged and older adults in Taiwan, as well as to explore the moderation effect of social media health literacy between health behavior and quality of life. This study was a cross-sectional study. Participants were citizens aged 55 years old, living in Taiwan, and who use social media. Convenience sampling was adopted to recruit participants from community centers in Taipei City and New Taipei City. The survey was also conducted through social media platforms. A self-reported, structured questionnaire was used for data collection, including personal background, social media health literacy, health behavior, and quality of life. Descriptive statistics, independent t-tests, One-way ANOVA, and linear regression analysis were performed for data analysis. A total of 330 validly responded. Results revealed there were significant differences in the score of social media health literacy among different sex and education groups. Age had a significant negative association, while time spent using social media had a significant positive association with the score of social media health literacy, respectively. Social media health literacy had a significant positive association with dietary behavior and quality of life, while it had a significant negative effect on smoking behavior. Furthermore, social media health literacy had a moderating effect between physical activity and quality of life. The variation of quality of life can be explained by sex, age, time spent using social media, chronic disease, social media health literacy and health behavior were 19.1%. This study indicates the importance of social media health literacy in middle-aged and older adults. This study suggests that fact-checking functions for health information on social media platforms. Enhancing social media health literacy to promote health behavior and quality of life is recommended for middle-aged and older adult populations. |
