Self-esteem as a Moderator of the Effects of Happiness, Depression, and Hostility on Suicidality Among Early Adolescents in Korea / 예방의학회지

OBJECTIVES: The purpose of this study was to investigate the role of self-esteem as a moderator of the factors influencing suicidality among middle-schoolers. METHODS: Moderated multiple regression analysis was applied to assess the influence of happiness, depression, and hostility on suicidality and to determine the degree to which self-esteem served as a moderator of those relationships. Data were collected from 268 students at a middle school in Busan, Korea, using a self-administered structured questionnaire. RESULTS: Happiness, depression, and hostility had significant direct effects on suicidality. Self-esteem showed no direct effect, but had a significant moderating effect on the relationship between hostility and suicidal behavior. CONCLUSIONS: These results suggest that various interventions, such as counseling programs, should be designed to alleviate hostility and depression and to enhance happiness and self-esteem among early adolescents.

The Association of Perceived Neighborhood Walkability and Environmental Pollution With Frailty Among Community-dwelling Older Adults in Korean Rural Areas: A Cross-sectional Study / 예방의학회지

OBJECTIVES@#The aim of this study was to evaluate the associations of frailty with perceived neighborhood walkability and environmental pollution among community-dwelling older adults in rural areas.@*METHODS@#The participants were 808 community-dwelling men and women aged 65 years and older in 2 rural towns. Comprehensive information, including demographics, socioeconomic status, grip strength, polypharmacy, perceived neighborhood environment (specifically, walkability and environmental pollution), and frailty, was collected from participants using face-to-face interviews conducted between June and August 2018. Perceived neighborhood walkability was measured using 20 items that were selected and revised from the Neighborhood Environment Walkability Scale, the Neighborhood Walkability Checklist from the National Heart Foundation of Australia, and the Physical Activity Neighborhood Environment Survey. The Kaigo-Yobo Checklist was used to assess participants’ frailty.@*RESULTS@#The overall prevalence of frailty in this community-dwelling population was 35.5%. Sex, age, cohabitation status, educational attainment, employment status, grip strength, and polypharmacy were significantly associated with frailty. In the logistic regression analysis, frailty was associated with low perceived neighborhood walkability (adjusted odds ratio [aOR], 0.881; 95% confidence interval [CI], 0.833 to 0.932; p<0.001) and severe perceived neighborhood environmental pollution (aOR, 1.052; 95% CI, 1.017 to 1.087; p=0.003) after adjusting for sex, age, cohabitation status, educational attainment, employment status, monthly income, grip strength, and polypharmacy.@*CONCLUSIONS@#More studies are warranted to establish causal relationships between walkability and environmental pollution and frailty.

The Relationship between Grief level and Suicidal Ideation of Elderly Living Alone and the Moderation Effect of Social Support / 農村醫學 地域保健

OBJECTIVES: The purpose of this study is to examine the moderating effect of social supports on the relationship between grief level and suicidal ideation of the elderly living alone. METHODS: We analyzed data from a questionnaire administered to subjects aged 65 years or older living alone for a 2017 community mental health project in Gyeongnam S city. To investigate the moderating effects of variables, we conducted a hierarchial regression analysis and confirmed the change R2. RESULTS: When adjusted for education and economic level, grief level had not a direct impact on suicidal ideation. And it was found that interdependent social support was moderating variables in the relationship of grief level and suicidal ideation of the elderly living alone. CONCLUSIONS: There is a need for appropriate programs that reduce suicidal ideation and therefore suicidal action. Moreover, it is especially necessary to enhance interdependent social supports.

Impact of Health-related Quality of Life in Firefighters: Focused on Posttraumatic Stress, Health-related Work Limitations, and Family Support / 한국직업건강간호학회지

PURPOSE: The purpose of this descriptive, cross-sectional study was to identify the factors affecting health-related quality of life by examining the relationships among posttraumatic stress, health-related work limitations, and family support in firefighters. METHODS: The data were collected from 390 firefighters working in four fire stations located in the G district using self-report questionnaires. The collected data were analyzed using descriptive statistics, t-test, one-way ANOVA along with the Scheffé test, and multiple regression. RESULTS: As per the results of multiple regression analysis, the factors affecting health-related quality of life in firefighters were posttraumatic stress, health-related work limitations, and family support. This model explained 31% of the variance in health-related quality of life (F=30.03, p<.001). CONCLUSION: Considering the findings of this study, there is a need to reduce posttraumatic stress and health-related work limitations and develop family support toward firefighters.

The Association between Hopelessness, Social Support and Community Integration and Depression among Elderly Living Alone / 農村醫學 地域保健

OBJECTIVES: This study was performed to investigate the association between hopelessness, social support and community integration, and depression. METHODS: We analyzed data from a questionnaire administered to subjects aged 65 years or older living alone for a 2015 community mental health project in Gyeongnam S city. We used a correlation analysis and a hierarchical regression analysis to identify factors that affect depression. RESULTS: When controlling for socio-demographic factors, hopelessness and community integration had significant effects on depression. That is, the higher the hopelessness (B=0.768, p<.001) and the lower the community integration (B=-0.163, p=.012), the higher the depression in elderly living alone . CONCLUSIONS: There is a need for approaches at both the individual and social levels that consider and improve measures to prevent and reduce depression. Moreover, it is especially necessary to enhance community integration.
