Objectives This study examined the associations between digital literacy and self-rated health (SRH), depression, and life satisfaction among older adults in the Republic of Korea.
Methods Data were obtained from the 2023 National Survey of Older Koreans (n=9,951). Digital literacy was evaluated based on participants’ ability to use 8 smartphone functions and their perceived difficulty adapting to a digital society. Dependent variables included SRH, depression (measured using the short form of Geriatric Depression Scale), and life satisfaction (assessed through a composite score across 7 domains). Multiple logistic regression was applied for SRH and depression, while linear regression was conducted for life satisfaction, adjusting for sociodemographic and health-related covariates.
Results Higher digital literacy was significantly associated with better SRH and greater life satisfaction. Compared to participants with no digital skills, those with moderate or high digital literacy had higher odds of reporting good SRH and significantly higher life satisfaction scores. Older adults who reported difficulty adapting to a digital society demonstrated significantly lower SRH and life satisfaction. However, after adjusting for covariates, the association between digital literacy and depression was not statistically significant.
Conclusion Higher digital literacy is linked to better SRH and greater life satisfaction. Moreover, digital literacy reduced the explanatory power of socioeconomic variables, suggesting that it serves as an important behavioral determinant. These findings underscore the importance of promoting digital literacy as a means of improving health equity and well-being in aging populations.

Objectives
The objectives of this paper are to examine the effects of religion and obesity on health and determine how the relationship varies by racial/ethnic groups with data from the Panel Study of American Race and Ethnicity (PS-ARE). Methods
Using ordinal logistic regression, the effects of religion and obesity on self-rated health and how the relationship varies by racial/ethnic groups are investigated. Additionally, to determine whether certain ethnic groups are more impacted by the frequency of religious attendance and obesity, whites, blacks, and Hispanics are analyzed separately with ordinal logistic regression. Results
When obesity was added in focal relationship between religious services attendance and self-rated health strengthened this focal relationship which is a suppression effect between religious services attending and self-rated health adding obesity. For BMI is also significantly associated with decreased odds of reporting better health–normal weight (OR = 2.99; 95% CI = 2.43–3.67) and overweight (OR = 2.19; 95% CI = 1.79–2.68) compared to obese. Subjects who attend religious services 1–2 time a year (OR = 1.30; 95% CI = 1.04–1.62) and 1–3 times a month (OR = 1.28; 95% CI = 1.05–1.57) are associated with increased odds of reporting better health. In whites, attending religious services 1–2 times a year are associated with increased odds of reporting better health (OR = 1.48; 95% CI = 1.09–2.00) and 1–3 times a month are also associated with increased odds of reporting health (OR = 1.34; 95% CI = 1.02–1.78) compared to never attending religious attendance. The frequency of religious services attendance of blacks and Hispanics are not associated with self-rated health. For BMI, being white is more positively associated with increased odds of reporting better health than black and Hispanic subjects. Although white subjects are less likely to attend religious services more frequently than black and Hispanic subjects, the influence on self-rated health in white subjects is more evidenced than other racial/ethnic groups. Conclusions
Although it was not proven that the association between participation in religious services and self-rated health is mediated by obesity, the research shows the suppression effect of obesity between participation in religious services and self-rated health.
