Mothers play a key role in ensuring their children’s healthy life. This study aimed to identify the maternal factors affecting problematic smartphone use in children. We adopted a cross-sectional descriptive design using structured questionnaires. Participants were fourth to sixth grade elementary school students in Korea (n = 184). The following maternal factors were evaluated: maternal mediation, children’s perception of mothers’ smartphone use, mother–child communication, and parenting style. Data regarding maternal factors’ effect on problematic smartphone use were analyzed by computing descriptive statistics and logistic regression analysis using SPSS Win 27.0. The results show that the maternal factors that influenced problematic smartphone use in children were maternal control over smartphone usage (odds ratio (OR) = 5.10, 95% confidence interval (CI): 1.33–19.60), smartphone usage time for social network service (OR = 1.52, 95% CI: 1.10–2.01), and problematic mother–child communication (OR = 1.07, 95% CI: 1.00–1.14). Therefore, to promote appropriate smartphone use among school children, it is necessary to develop an intervention comprising maternal supervision of their children’s smartphones, guidance provision for social network service usage, and strategies for the reinforcement of positive mother–child communication.

With the increase in the older population, there is a concern for health in older adults. This study aimed to develop a physical exercise program that combined walking and gymnastics for older adults residing in rural areas and to evaluate its effect on their physiological and psychological health and physical function. A quasi-experimental design was adopted. Participants were aged 65 years or older, with 94 and 130 participants in the experimental and control group, respectively. The program was implemented for seven months, from April–October 2016. Walking and gymnastics were performed once a week each, for about 60 and 50 min, respectively. Data were analyzed using the Chi-squared test, Fisher’s exact test, independent t-test, or Mann–Whitney U test. Results revealed that the experimental group participants displayed improved waist circumference (t = 1.70, p = 0.045), body mass index (U = 4691.00, p = 0.002), depressive symptoms (t = −2.94, p = 0.002), upper limb strength (t = 2.27, p = 0.012), and lower limb strength (t = 3.86, p < 0.001). Therefore, it can be presumed that the physical exercise program was effective and beneficial for older adults living in rural areas. This program is expected to contribute to maintaining and improving their health if implemented regularly in the future.

Suicide is the topmost cause of death among adolescents in South Korea and is deeply related to depression. This study aimed to identify gender differences in the factors affecting depression among multicultural adolescents. This study is a secondary analysis using data from a national survey, the Multicultural Adolescents Panel Study (MAPS) conducted in 2017. The participants were 1160 multicultural adolescents ranging from 15 to 18 years, living in Korea, and whose fathers were Koreans and mothers were foreigners. The results showed that depression scores were higher for females (18.35) than males (16.38, t = 6.42, p < 0.001). In total, seven factors affected depression among male multicultural adolescents’ and the model explained 50.5% of the total variance (F = 77.99, p < 0.001), while four factors affected female multicultural adolescents’ depression, and the model explained 51.4% of the total variance (F = 100.02, p < 0.001). Significant gender differences were found in factors that influence depression among multicultural adolescents. Therefore, depression prevention programs for multicultural adolescents need to vary according to gender. Additionally, these programs should target families and teachers of multicultural adolescents as well.

Purpose: This study investigated differences in the relationships of factors including emotional problems, self-perception, parental behavior, and peer attachment with smartphone dependency (SD) among middle school, high school, and college students in South Korea. Methods: This study used data from a nationwide sample of 1,882 middle school, 1,821 high school, and 1,346 college students who owned smartphones. Descriptive statistics and multiple regression analysis were conducted to investigate the predictors of SD based on school level. Results: SD scores significantly differed across school levels. Female gender, more aggressive behavior, less ego-identity, and less monitoring parental behavior were linked to higher SD at all school levels. Less self-esteem and intrusive parental behavior were linked to SD in middle school students. In high school students, additional factors related to higher levels of SD were resilience, intrusive / inconsistent parental behavior, peer trust and alienation, and depression. Additionally, resilience, over-expectant parental behavior, and peer trust were linked to higher SD in college students. Conclusion: This study provides insights into SD and predictors of SD among middle school, high school, and college students. Based on these findings, SD prevention programs should be developed according to the developmental stages of adolescents and young adults.
