This study identified the acceptance of disability’s impact on self-esteem among adults with disabilities in South Korea. This is a four-year follow-up study that obtained data from the Panel Survey of Employment for Persons with Disabilities from 2017 to 2020. In total, 3329 individuals participated. Logistic regression examined the acceptance of disability’s effect on self-esteem. These variables were categorized based on the acceptance of disability (high→high, low→high, high→low, and low→low) and self-esteem (low and not low). Compared to the participants with a consistently high acceptance of disability, those with constantly low acceptance were 2.35 times (95% CI 1.81–3.04) more likely to have low self-esteem. When the acceptance of disability was low→high and high→low, the low self-esteem probability was 1.23 and 1.66 times, respectively. Low self-esteem was prominent for the following: men, 50–64-year olds, married, urban, economic activists, the mid–low household income category, and those with sensory disability. Acceptance of disability can adversely affect self-esteem when it is consistently low or changes from high to low. Among socio-economic factors, there were several risk factors that could make individuals more vulnerable to low self-esteem. Therefore, it is necessary to help people accept their disabilities to maintain healthy self-esteem levels.

Objective: This study aimed to explore the associations between smartphone overdependence (smartphone addiction) and suicidal ideation and attempts among Korean adolescents to acknowledge the risk of smartphone overuse. Methods: Data were obtained from the results of the 2020 Korea Youth Risk Behavior Web-based Survey. Smartphone addiction was categorized into three groups: adolescents who scored less than 23 were categorized as the general user group and formed the reference, those with scores of 23–30 were categorized as the potential-risk user group, and those with scores higher than 31 were categorized under the high-risk user group. Suicidal ideation and suicide attempt were identified as dependent variables in the present study. Multiple logistic regression was used to analyze the relationship between SA and suicidal ideation and suicide attempt status among Korean adolescents. Results: This study included 41,173 general users of smartphones, 12,142 potential-risk users, and 1633 high-risk users from among 54,948 adolescents who were middle- and high-school students. Adolescents with potentially risky smartphone use showed a higher likelihood of suicidal ideation (OR: 1.50, CI: 1.42–1.60). Similarly, adolescents with high-risk smartphone use showed a significant risk of suicidal ideation (OR: 2.49, CI: 2.21–2.81) and suicide attempt (OR: 1.87, CI: 1.48–2.37) compared to the adolescents who were general users. Conclusion: Our study results encourage parents and social workers to acknowledge that adolescents’ smartphone addiction leads to a higher risk to their mental health, wherein they may engage in suicidal ideation and even resort to a suicide attempt.

These days, it is not common for people to have time to do physical activities regularly because of their own work. So, they perform physical activities all at once, which is often called the “weekend warrior”. Therefore, this study aimed to examine the association of the “weekend warrior” and other physical activity patterns with metabolic syndrome. Data from the Korea National Health and Nutrition Examination Survey were used, and 27,788 participants were included. The participants were divided into inactive, weekend warriors, and regularly active based on physical activity patterns. The risk of metabolic syndrome in each group was analyzed using multiple logistic regression. The inactive and weekend warrior groups showed a higher likelihood of developing metabolic syndrome than the regularly active groups (weekend warrior: odds ratio (OR) 1.29, confidence interval (CI) 1.02–1.65; inactive: OR 1.38, CI 1.25–1.53). According to the physical activity patterns, the weekend warrior group showed a dose-response relationship compared to the regularly active group (only moderate: OR 1.85, CI 1.25–2.72; only vigorous: OR 1.41, CI 0.93–2.14; both: OR 0.84, CI 0.56–1.27). This study found increasing the amount of physical activity and performing vigorous-intensity physical activity helped manage metabolic syndrome in the weekend warrior group.

This cross-sectional study identified the association between COVID-19-related perceived household financial decline and smartphone dependency among adolescents in South Korea. Data from the 2020 Youth Risk Behavior Survey of Korea was used and 54,809 middle and high school students were included. COVID-19-related perceived household financial decline was categorized as no financial decline, mild, moderate, and severe. Smartphone dependency was calculated by 10 questions and was largely categorized as yes and no, and as normal, low, and high (prevalence rate: 25.0%). Binary and multinomial regression analyses were performed to analyze the association. The more severe the financial decline, the more pronounced the risk of high-risk smartphone dependency (mild financial decline: odds ratio (OR) 1.11, 95% CI 0.96–1.28; moderate: OR 1.22, 95% CI 1.04–1.43; severe: OR 2.56, 95% CI 2.06–3.17). Poor family relationships (OR 1.06, 95% CI 1.03–1.10) and severe social conflict (OR 2.99, 95% CI 2.50–3.58) were also related to smartphone dependency. The ORs were 2.63 with more than three bathrooms and 1.63 with their own bedroom. Smartphone dependency among adolescents is closely related to COVID-19-related perceived household financial decline. As smartphone dependency relates to complicated psychological issues, further evaluation is necessary, especially for vulnerable adolescents.
