Mental Health and Smoking-Related Determinants of Alcohol Drinking Experience in Korean Adolescents.

This study aimed to identify the determinants of mental health and smoking-related behaviors among Korean adolescents with drinking experience. Secondary data from the Korean Youth Risk Behavior Web-based Survey (2021) were analyzed. The final study sample consisted of data from 5905 adolescents with a history of smoking. Chi-square and multivariate logistic regression analyses were used to examine the factors related to drinking experience. The factors that influenced alcohol drinking were sex, school level, academic performance, self-reported depression, and smoking. The results of this study showed that there are numerous factors affecting adolescents' drinking experience. Early education and interventions are needed to reduce alcohol consumption among adolescents. Integrated attention and support from society, school, and family are necessary so that they can cope with and adapt to stress in a healthy way.

Associated factors of depression in pregnant women in Korea based on the 2019 Korean Community Health Survey: a cross-sectional study.

Purpose: Various individual and social factors influence depression in pregnant women. The purpose of this study was to identify the influence of socioeconomic status, health behaviors, and health status on depression of pregnant women in Korea. Methods: This study analyzed data from the 2019 Korean Community Health Survey conducted from August to October 2019. A structural questionnaire with Patient Health Quetsionnaire-9 (PHQ-9), health behavior, health status, and psychological characteristics was used. The data of 1,096 pregnant women between the ages of 19 and 55 years were analyzed using descriptive statistics, independent-test and chi-square tests, and multiple regression. Results: The mean score of prenatal depression as measured by the PHQ-9 during pregnancy was 2.35 points out of 0 to 27 points. Low income (B=0.69, p<.001), low-education level (B=0.70, p<.001), skipping breakfast (B=0.34, p=.001), less than 8 hours of sleeping (B=0.26, p=.009), binge drinking during pregnancy (B=0.46, p=.001), and stress (B=1.89, p<.001) were significantly associated with increased depression scores. In contrast, depression scores significantly decreased as subjective health status (B=-0.59, p<.001) and subjective oral health status (B=-.17, p=.003) increased. Conclusion: Findings support the need for healthcare policies and clinical screening to alleviate prenatal depression, especially for pregnant women with low socioeconomic status, poor health behavior, poor health status, and high stress.

The Effect of COVID-19-Related Lifestyle Changes on Depression.

OBJECTIVE: This study aimed to identify the effect of coronavirus disease (COVID-19)-related lifestyle changes on depression. METHODS: This secondary data analysis study included 229,269 adults from a community health survey conducted in the South Korea in 2020. Data were collected using a structured questionnaire about participants' lifestyle changes related to COVID-19 and the Patient Health Questionnaire-9. The data were analyzed using a complex sample independent t-test, analysis of variance, Pearson's correlation coefficient, and multiple regression analysis. RESULTS: The mean age of the participants was 48.76; 49.6% were male, and 50.4% were female. The multiple regression showed that depression increased due to COVID-19-related lifestyle changes (physical activity, sleep duration, consumption of convenience foods, alcohol consumption, smoking, and use of public transportation). The explanatory power was 27.3%, and the model was suitable (Wald F=63.75, p<0.001). CONCLUSION: This study identified the effect of COVID-19-related lifestyle changes on depression, and the results have implications for future depression-relieving interventions.

A Study on the Reliability and Validity of the Korean Health Literacy Instrument for Late School-Aged Children.

This study aimed to develop and validate the Korean Health Literacy Instrument, which measures Korean late school-aged children's understanding capacity. The construct's concepts were drawn from the literature review and interviews with school nurses and teachers. A survey was then conducted in 552 fifth and sixth graders in nine elementary schools, from 1 to 9 May 2014. The KR-20 coefficient for reliability, difficulty index, discrimination index, item-total correlation, and known group technique for validity were performed. An exploratory factor analysis was performed to test the construct validity of the instrument and its unidimensionality. The results reveal that a two-factor structure was appropriate for the Korean school-age health literacy tool (root mean square error of approximation = 0.06, Comparative Fit Index = 0.96, and Tucker-Lewis Index = 0.95). From the remaining 16 items, the internal consistency reliability coefficient of this instrument was 0.85, and the criterion-related validity was 0.62 (p < 0.001). The Korean health literacy instrument for late school-aged children was suitable for screening individuals who have limited health literacy. Based on the findings of this study, future studies must continue to conduct empirical investigations on the Korean health literacy instrument for late school-aged children.

Factors Related to Maternal Oral Health Status: Focus on Pregnant and Breastfeeding Women.

Oral health management is vital for pregnant women and their fetuses. This study analyzed the factors affecting maternal oral health status. It used secondary data obtained from the 2019 Korean Community Health Survey. Data were analyzed using SPSS 21.0 for complex descriptive statistics, independent t-test, Pearson's correlation coefficients, and multiple regression analysis. Multiple regression analysis revealed that age (ß = -0.01, p < 0.001), maternal characteristics (ß = -0.10, p < 0.001), education (ß = -0.06, p = 014), subjective health status (ß = 0.27, p < 0.001, sleep duration (ß = 0.07, p = 0.003), breakfast frequency (ß = -0.16, p < 0.001), unmet dental care needs (ß = 0.35, p < 0.001), and depression (ß = -0.02, p < 0.001) are key factors of maternal oral health status. Furthermore, oral health status is associated with mental health factors, such as depression. Therefore, the importance of maternal oral health among pregnant and breastfeeding women must be highlighted to promote the health of mothers and their babies.

The Effects of Lifestyle Interventions on the Health-Promoting Behavior, Type D Personality, Cognitive Function and Body Composition of Low-Income Middle-Aged Korean Women.

Low-income middle-aged women (LMW) who are vulnerable have various physical and psychosocial problems. They need lifestyle interventions to actively cope with these risk factors. This study used a randomized control group pretest-posttest design. LMW aged from 40 to 60 years were recruited and randomly assigned to an experimental group (n = 31) and a control group (n = 32). The lifestyle interventions for this study, which were implemented for eight weeks, included nutritional management, physical activity, stress management and cognitive function improvement based on King's goal attainment theory. The measured outcomes were health-promoting behaviors, Type D personality, cognitive function and body composition. The experimental group scored significantly higher than the control group for health-promoting behaviors (effect size (ES) = 0.68~1.27, p < 0.001~0.014) and cognitive function (ES = 0.79~1.31, p < 0.001~0.005). The negative affectivity (ES = 0.70, p = 0.012) and the prevalence of a Type D personality (x2 = 4.39, p = 0.047) and the systolic blood pressure (ES = 0.65, p = 0.019) decreased significantly in the experimental group compared with the control group. Lifestyle interventions for LMW were effective in improving health-promoting behavior, Type D personality traits and cognitive function.

Factors affecting unmet healthcare needs of low-income overweight and obese women in Korea: analysis of the Korean National Health and Nutrition Examination Survey 2017.

Purpose: The purpose of this study was to explore unmet healthcare needs among low-income overweight and obese women and to identify the factors affecting unmet healthcare needs. Methods: The study was a secondary analysis of data from the 2017 Korea National Health and Nutrition Examination Survey. A final sample of 388 out of 8,127 participants was analyzed using complex descriptive statistics, the chi-square test, the independent t-test, and logistic regression. Results: The mean age of the participants was 66.51±1.05 years. Unmet healthcare needs were experienced by 19.4% of low-income overweight and obese women. Women with depression, stress, and poor self-reported health status were significantly more likely than their counterparts to experience unmet healthcare needs. Poor self-reported health status was confirmed to be related to unmet health needs in low-income overweight and obese women (odds ratio, 2.65; p=.011). Conclusion: The study provides the novel insight that the unmet healthcare needs of low-income overweight and obese women were influenced by self-reported health status. Healthcare providers should make efforts to develop strategies to reduce unmet healthcare needs among low-income overweight and obese women, who constitute a vulnerable population.

Factors associated with maintenance of smoking cessation in adolescents after implementation of tobacco pricing policy in South Korea: Evidence from the 11th Youth Health Behavior Survey.

As a part of Korea's smoking cessation policy, the price of tobacco was increased in January 2015. Initially, the smoking rate among adolescents began to decrease. The current data, however, show that the adolescent smoking rate is on the rise. Alongside price policies, there is a need to further understand additional preventive measures that promote successful smoking cessation by identifying the factors that influence maintenance of smoking cessation in adolescents. This study aimed to identify the factors that influence smoking cessation in adolescents after attempting smoking cessation after increase in tobacco price. The study used large-scale, nationwide, secondary data obtained from the Korean Youth Risk Behavior Web-Based Survey. The sample included a total of 627 subjects who reported an attempt to quit smoking after the tobacco price increased. Descriptive statistics, t test, the χ2 test, and multiple logistic regression were used. The results showed that household economic status, school type, suicidal ideation, experience of exposure to secondhand smoke at home, and experience of witnessing teaching staff smoking were significant factors related to maintenance of smoking cessation among adolescents. To increase the success rate of smoking cessation, future intervention programs should include school environment structure and address emotional and psychological issues such as suicide.
