Adolescents are particularly vulnerable to smartphone overdependence. Therefore, we identified the factors influencing smartphone overdependence and risk subgroups among adolescents. The current study is a secondary analysis of nationally representative data from the 2020 Korea Youth Risk Behavior Survey. The survey targeted middle- and high-school students in South Korea aged 12–18 using stratified, clustered, multistage probability sampling, and 53,457 students from 793 schools participated in this study. Complex sample data were analyzed considering the strata, clusters, and weights. Multiple logistic regression analysis revealed age, gender, household economic status, anxiety, loneliness, depressive symptoms, and experience of violent treatment as significant predictors of smartphone overdependence. Adolescents with severe anxiety were at a 3.326 times higher risk of smartphone overdependence than adolescents with minimal anxiety. Decision tree analysis showed that anxiety, gender, loneliness, and depressive symptoms were important in differentiating risk subgroups, with anxiety being the most significant factor. Group 13, comprising girls with severe anxiety, had the highest risk at 52.9%. Thus, early detection and prevention of issues such as anxiety, loneliness, and depressive symptoms, as well as treatment for violence, can prevent smartphone overdependence among adolescents. Additionally, more thorough interventions for anxiety are warranted to prevent smartphone overdependence.

There is a lack of evidence regarding the effects of exercise on older individuals living with HIV. This systematic review and meta-analysis examined previous studies on physical activity interventions for people living with HIV aged ≥50 years. The effectiveness of the interventions on various physical and psychological health outcomes was evaluated. Databases used for this review included PubMed, EMBASE, CINAHL, and Cochrane Library CENTRAL. Twelve randomized controlled trials on physical activity interventions for people ≥50 years and living with HIV were included. Standardized mean differences were calculated using random-effect models. All effect sizes were expressed using Cohen’s d values and their 95% confidence intervals (CIs). Physical activity interventions had a significant effect on walking capacity (Cohen’s d: 0.467; 95% CI [0.069, 0.865]). The effect sizes on cardiorespiratory fitness, weight, and health-related quality of life were not significant. These findings suggest that physical activity interventions for people living with HIV aged ≥50 years are effective for the improvement of walking capacity. Further larger and higher-quality studies are required to determine the full effects of physical activity interventions on various health outcomes among older adults with HIV.

This review was performed to evaluate the effects of robot interventions on cognitive and psychological outcomes among older adults with cognitive impairment. Three databases (PubMed, Embase, and Cochrane Central Register of Controlled Trials) were searched for studies published in English between January 2015 and August 2021. We included studies that involved older adults with cognitive impairment, interventions using robots, outcome measures related to cognitive and psychological status, and randomized controlled trials. Ten studies included in the systematic review, and nine studies derived from these ten articles were included in the meta-analyses. The meta-analyses revealed that robot interventions significantly decreased anxiety and agitation but exerted no significant effects on cognitive function, neuropsychiatric symptoms, and quality of life. The subgroup analyses according to robot types revealed that pet-type robot interventions reduced anxiety and agitation. In addition, subgroup analysis according to the intervention format of robot interventions found that individual intervention was effective for improving agitation, but a group-based intervention was effective for improving depression. We suggest using robot interventions to improve psychological outcomes such as anxiety and agitation; however, further research is needed to determine whether robot interventions affect symptoms such as cognitive function, neuropsychiatric symptoms, and quality of life.

The home environment is increasingly emphasized as a key factor in home falls among frail older people. In this study, we aimed at exploring and synthesizing empirical studies that considered the environmental factors of home falls among frail older people. We performed a systematic review to draw comprehensive conclusions regarding these environmental factors by searching MEDLINE, CINAHL, Embase, and Cochrane Library, as well as gray literature databases. Intervention and nonintervention studies that specifically reported home environmental factors related to falls in community-dwelling frail older people aged 65 years and over were selected. Of the 8374 studies initially retrieved, seven intervention and seven nonintervention studies were included in the analysis. In seven of the 14 studies, environmental hazards were evaluated using relevant assessment tools. Interventions were provided for the bathroom/toilet, bedroom, living room, and for slipping and tripping, identified as frequent fall locations and situations, respectively, through nonintervention studies. The most common intervention was to provide advice/counseling and disseminate information to enhance knowledge after visiting the home and evaluating the home environmental factors that could affect falls. In the majority of the studies, the intervention was of a multicomponent nature, and in only two intervention studies was there practical modification of the home environment to lower the fall risk. In all the four studies with statistically significant results, the intervention was provided by a multidisciplinary team. Through this review, we identified environmental factors for home falls, helping clinicians and health professionals gain a better understanding of the situation to prevent recurrence in frail older people who have experienced falls. The findings indicate that comprehensive standardized environmental evaluations should be conducted considering older people’s functional characteristics and needs and that the intervention process requires the participation of older people with a multidisciplinary team.

Background: The health care paradigm is being challenged to put greater emphasis on promoting a healthy lifestyle and provide patient-customized care in a rapidly changing Korean society. Within such changes, it is worthwhile to identify how the meaning of a good nurse may be changing.Objective: This study explores the meaning of a good nurse from the perspective of nurses themselves.Methods: In-depth interviews were conducted with ten nurses who worked at senior general hospitals or governmental agencies using purposeful sampling. Individual interviews were done until data saturation was reached. The key question was “What does a good nurse mean to you?” After the interview, content analysis was done.Results: Six main themes and 16 subthemes were identified. The main themes showed that a good nurse was someone who ‘leans in toward the patient’, ‘provides professional care’, ‘keeps the cornerstone of one’s mind with a positive attitude’, ‘maintains a good relationship with colleagues’, ‘matures with her/his nursing philosophy and conviction’, ‘contributes to society’.Conclusion: This study provides basic data for exploring nurses’ self-image as a professional. Specifically, social role and macro level responsibilities were identified with nurses’ internal aspects such as a positive attitude, and nursing philosophy. The necessity of socio-environmental support for nurses was also emphasized. In addition, the results of this study can be used at the policy level to provide a better balance for development of good nursing.
