    This study examined the relationships among exercise motivation, exercise self-efficacy, and physical activity rating, as well as the role of exercise self-efficacy in the above relationship. A survey was conducted among 362 college students (aged 19.0 ± 0.8 years, 185 males and 177 females) from a Chinese college using exercise motivation, self-efficacy, and physical activity assessment scales. The results revealed significant sex differences in exercise motivation, self-efficacy, and physical activity scores. Structural equation analysis revealed that ability motivation had a direct effect, accounting for 41.5% of the total effect, while the mediating effect of exercise self-efficacy accounted for 58.5%. Exercise self-efficacy has been proven to be a key predictor of physical activity in both general analysis and gender stratification analysis. From the results of path analysis, in the overall sample and the male group, the influence intensity of each variable on physical activity is the direct effect of exercise self-efficacy, the mediating effect of exercise self-efficacy and the direct effect of ability motivation. However, different influence patterns were observed in female groups: the direct effect of exercise self-efficacy still ranked first, followed by the direct effect of ability motivation, and finally, the mediating effect of exercise self-efficacy. This finding suggests that gender may be an important variable regulating the relationship between exercise self-efficacy and physical activity. Based on the above findings, this study emphasizes that gender-specific strategies should be adopted when formulating intervention programs for physical activity promotion: for male groups, it should focus on strengthening the cultivation of exercise self-efficacy, while for female groups, it should also focus on the improvement of ability motivation and the establishment of self-efficacy. This study provides an important empirical basis for improving the theory of health behavior promotion.

    BACKGROUND: Misinformation has had a negative impact upon the global COVID-19 vaccination program. High-income and middle-income earners typically have better access to technology and health facilities than those in lower-income groups. This creates a rich-poor divide in Digital Health Literacy (DHL), where low-income earners have low DHL resulting in higher COVID-19 vaccine hesitancy. Therefore, this cross-sectional study was undertaken to assess the impact of health information seeking behavior on digital health literacy related to COVID-19 among low-income earners in Selangor, Malaysia.

    METHODS: A quantitative cross-sectional study was conducted conveniently among 381 individuals from the low-income group in Selangor, Malaysia. The remote data collection (RDC) method was used to gather data. Validated interviewer-rated questionnaires were used to collect data via phone call. Respondents included in the study were 18 years and older. A normality of numerical variables were assessed using Shapiro-Wilk test. Univariate analysis of all variables was performed, and results were presented as means, mean ranks, frequencies, and percentages. Mann-Whitney U test or Kruskal Wallis H test was applied for the comparison of DHL and health information seeking behavior with characteristics of the participants. Multivariate linear regression models were applied using DHL as dependent variable and health information seeking behavior as independent factors, adjusting for age, gender, marital status, educational status, employment status, and household income.

    RESULTS: The mean age of the study participants was 38.16 ± 14.40 years ranging from 18 to 84 years. The vast majority (94.6%) of participants stated that information seeking regarding COVID-19 was easy or very easy. Around 7 percent of the respondents cited reading information about COVID-19 on the internet as very difficult. The higher mean rank of DHL search, content, reliability, relevance, and privacy was found among participants who were widowed, had primary education, or unemployed. An inverse relationship was found between overall DHL and confidence in the accuracy of the information on the internet regarding COVID-19 (β = -2.01, 95% CI = -2.22 to -1.79).

    CONCLUSION: It is important to provide support to lower-income demographics to assist access to high-quality health information, including less educated, unemployed, and widowed populations. This can improve overall DHL.
