Background and Objectives: To evaluate the impact of smoking in young adults on the risk of cardiovascular disease (CVD) and the clustering effect of behavioral risk factors such as smoking, obesity, and depression. Methods: A Korean nationwide population-based cohort of a total of 3,280,826 participants aged 20-39 years old who underwent 2 consecutive health examinations were included. They were followed up until the date of CVD (myocardial infarction [MI] or stroke), or December 2018 (median, 6 years). Results: Current smoking, early age of smoking initiation, and smoking intensity were associated with an increased risk of CVD incidence. Even after quitting smoking, the risk of MI was still high in quitters compared with non-smokers. Cigarette smoking, obesity, and depression were independently associated with a 1.3-1.7 times increased risk of CVD, and clustering of 2 or more of these behavioral risk factors was associated with a 2-3 times increased risk of CVD in young adults. Conclusions: In young adults, cigarette smoking was associated with the risk of CVD, and the clustering of 2 or more behavioral risk factors showed an additive risk of CVD.

Purpose: Vitamin D has been known to play an important role in the central nervous system and brain functions in the human body, and cumulative evidence has shown that vitamin D deficiency might be linked with various mental health conditions. Epidemiologic studies have shown that vitamin D deficiency may be associated with higher risk of depression in the US and European populations. However, limited information is available regarding the association between vitamin D status and depression in the Korean population. The objective of this study was to examine the associations between vitamin D levels and prevalence of depression. Methods: We conducted a cross-sectional analysis using nationally representative data from the 2008-2010 Korean National Health and Nutrition Examination Survey from which serum 25-hydroxyvitamin D concentrations were available. A total of 18,735 adults who had available demographic, dietary, and lifestyle information were included in our analysis. We defined "depression" with a diagnosis by a physician. "Depressed condition" was defined as having feelings of sadness or depression without diagnosis by a physician. Results: The prevalence of depression was 1.63% and 5.43% in Korean men and women, respectively; 12.5% of men and 26.1% of women were defined as the group having depressed conditions. In multivariate logistic regression models, no significant associations were observed between vitamin D status and prevalence of depression or depressed conditions in Korean men and women. Conclusion: We found no association between vitamin D insufficiency and depression/depressed conditions in Korean adults. Future large prospective studies and randomized controlled trials are needed to confirm this relationship.

Purpose: This study was a part of preliminary survey for establishing Korean HPS(Health Promoting School) model which was originally suggested by WHO. Methods: Three elementary and middle schools were sampled in urban and rural area across three level of social-economic status, and survey was conducted on one class in each grade by random selection. To measure mental health and social and familial factors, self-esteem scale, self-efficacy scale, depression scale, family cohesion scale, parent-child communication scale, adolescent's mental health and problem behavior questionnaire(AMPQ), and other question items about family status and economic level were conducted. Students' mental health level was compared by region, sex, grade, and other familial and economic factors. Results: Familial and social factors such as economical and educational level of parents, number of family members were different between rural and urban area. Also, students of rural area got lower scores at self-esteem, self-efficacy, but higher scores at extroverted problem behavior than their urban counterparts. In pre-school students, high grade students' self-esteem, and family cohesion scores were lower than low grade students. And sexual differences were found across problem behavior domain and region in middle school students. Especially, the students of single-parent family and lower economic family got insistently low scores at various mental health related scales. Conclusion: These results should be considered, when the HPS model is designed and applied in Korea.

This study analyzed the differences in the general characteristics, mental and health-related factors, eating habits, and nutrient intake of Korean male youths before and after the outbreak of the coronavirus disease 2019 (COVID-19). The data of a total of 1,231 subjects, from among the participants in the 2018 and 2020 Korea National Health and Nutrition Examination Survey (KNHANES), were analyzed. The 2020 group had fewer married members than the 2018 group. The subjects in the 2020 group weighed more (P<0.05), had a higher waist circumference (P<0.01), and showed greater weight gain (P<0.05) than the 2018 group subjects. The aerobic physical activity of the 2020 group was lower (P<0.01) compared to the 2018 group. The members of the 2020 group had higher depression scores (P<0.01), suicidal tendencies (P<0.01), and need for counseling for mental problems (P<0.05) than those of the 2018 group. The prevalence of high fasting blood sugar levels and diabetes was higher in the 2020 group compared to the 2018 group. The frequency of breakfast (P<0.01) and dining out (P<0.001) and the proportion of breakfast (P<0.01) and dinner (P<0.05) taken with the family or non-family members was lower in the 2020 group than in the 2018 group. The rate of dietary supplement intake of the 2020 group was higher than that of the 2018 group (P<0.01). There were significant differences in the protein (P<0.05), riboflavin (P<0.01), and carbohydrate (P<0.01) intakes between the two groups. These results suggest that male youths had a higher waist circumference and high levels of depression, and showed a decrease in frequency of breakfast intake and dining out after the out break COVID-19 pandemic. Therefore, nutrition and health promotion programs are urgently needed to improve mental health, other health-related factors and nutritional status of male adults that are associated with the COVID-19 pandemic.

Purpose: This study was a systematic review and meta-analysis to explore the factors related to quality of life in heart transplant recipients. Methods: To identify studies that suggested the factors related to the quality of life in heart transplant recipients, we searched the articles published from 1974 to November 2018 using Six databases, PubMed, CINAHL, EMBASE, Cochrane, KMBASE and RISS. A total of 22 studies were selected out of 5,234 for the systematic review and meta-analysis on the basis of the PRISMA flow. The quality of study was assessed by assessment tool form the NIH and meta-analysis was performed using the 'R 3.5.2' version to analyze the correlated effect sizes. Results: Factors related to quality of life in heart transplant recipients were categorized into six domains based on the health-related quality of life model introduced by Ferrans: individual, environmental, biological function, symptoms, functional status, and general health perception. In the meta-analysis, 34 factors were used and 17 factors having significant effect sizes were as follows: self-efficacy, demoralization, perceived control, current occupational status, age, marital status, health promotion life style in the individual characteristics; stress in environmental characteristics; physical function status, creatinine level, left ventricular ejection fraction (LVEF) in biological function; anxiety, depression, symptom frequency and distress in symptoms domain; coping, self-care compliance in functional status. Conclusion: The findings indicate that the multi-dimensional factors influencing the quality of life in heart transplant recipients and provide the evidence for developing effective interventions for improving the quality of life of recipients.
