Objectives: Mental health disorders and suicide are an important and growing public health concern in Korea. Evidence has shown that both globally and in Korea, obesity is associated with an increased risk of developing some psychiatric disorders. Therefore, we examined the association between distorted body weight perception (BWP) and suicidal ideation. Methods: Data were obtained from the 2007-2012 Korea National Health and Nutritional Evaluation Survey (KNHANES), an annual cross-sectional nationwide survey that included 14 276 men and 19 428 women. Multiple logistic regression analyses were conducted to investigate the associations between nine BWP categories, which combined body image (BI) and body mass index (BMI) categories, and suicidal ideation. Moreover, the fitness of our models was verified using the Akaike information criterion. Results: Consistent with previous studies, suicidal ideation was associated with marital status, household income, education level, and perceived health status in both genders. Only women were significantly more likely to have distorted BWP; there was no relationship among men. In category B1 (low BMI and normal BI), women (odds ratio [OR], 2.25; 95% confidence interval [CI], 1.48 to 3.42) were more likely to express suicidal ideation than women in category B2 (normal BMI and normal BI) were. Women in overweight BWP category C2 (normal BMI and fat BI) also had an increased OR for suicidal ideation (OR, 2.25; 95% CI, 1.48 to 3.42). Those in normal BWP categories were not likely to have suicidal ideation. Among women in the underweight BWP categories, only the OR for those in category A2 (normal BMI and thin BI) was significant (OR, 1.34; 95% CI, 1.13 to 1.59). Conclusions: Distorted BWP should be considered an important factor in the prevention of suicide and for the improvement of mental health among Korean adults, especially Korean women with distorted BWPs.

Chronic pain is one of the leading causes of hospital visits. It not only affects the patients themselves but also has a major negative impact on their families and society. In this study, we investigated epidemiology of musculoskeletal disorders induced chronic pain among general population based on Korea National Health and Nutrition Examination Survey database and also analysed how it influenced on the use of medical services. This study was done by using the data of 5th Korea National Health and Nutrition Examination Survey (KNHANES V), taking aged 20 years and over adults as research subjects. The EuroQoL-5 Dimension Index(EQ-5D) was used as a survey instrument. T-test, chi-square test and multivariate logistic regression were used for statistical analysis. Subjects with chronic pain had a higher likelihood than control group to use medical services(odds ratio : 5.858, confidence interval 3.636-9.438). Controlling for existence of chronic pain, more women were likely to use medical services than men(1.156, 0.707-1.889). Age, gender and household income level did not affect the use of medical services. Proper control of chronic pain is very helpful in improving patient's quality of life and it also accounts for a large proportion in suppressing excessive consumption of medical services. Anesthesia and pain medicine specialists have superior knowledge about analgesics and anticonvulsants than other physicians do and also have specialized skills to perform procedures like nerve blocks in treating chronic pain. Therefore Anesthesia and pain medicine specialists need to play a leading role in managing chronic pain.

This study aims to identify the multiple trajectories of depressive symptoms and the characteristics of each trajectory group among the elderly. This study uses five waves of longitudinal data from the Korean Welfare Panel Study (KWPS, 2006-2010). Subjects were older adults aged 60 and over who had completed at least three waves between 2006 and 2010. A total of 4,181 respondents were analyzed. The latent growth mixture model and the multiple logistic regression model were mainly used for data analysis. The major findings were as follows: After controlling for the variables of gender, age, education, marital status, self-assessed health, and poverty, this study identified four different trajectory classes: stable low depressive symptoms (71.8%), high but decreased depressive symptoms (10.6%), moderate but increased depressive symptoms (7.9%), and an increased, then a decreased pattern of depressive symptoms (9.7%). The characteristics of theses trajectories as compared to previous studies were a lower percentage of 'stable low depressive symptoms', no 'persistently high depressive symptoms', and higher level of depressive symptoms. Also, the elderly in the stable low trajectory group had better health status, higher self-esteem and a good relationship with family members, having longer working periods, and more living in non-poverty. In addition, chronic health problems, loss of spouse, and household income differentiated the increased and then decreased pattern from the low stable pattern. Also, age and public pension differentiated the moderated but increased pattern from the low stable pattern. Based on the findings of this study, the researchers suggested political and practical implications for reducing depressive symptoms in later life.

Opportunistic screening for lung cancer is commonly conducted in Korea in accordance with physician recommendations and screenee's preferences. However, studies have yet to thoroughly examine the public's understanding of the risks posed by lung cancer screening. This study was conducted to assess changes in intentions to undergo lung cancer screening in response to being informed about exposure to radiation during low-dose computed tomography (LDCT) tests and to identify factors with the greatest influence thereon among Korean men. We conducted sub-group interviews among men chosen from the 2013 Korea National Cancer Screening Survey (KNCSS), a nationwide, population-based, cross-sectional survey of men aged 40 to 74 years and women aged 30 to 74 years. From 4100 participants in the KNCSS, 414 men who underwent any cancer screening test within the last 2 years were randomly selected for inclusion in this study. Via face-to-face interviews, their intentions to undergo lung cancer screening were assessed before and after being informed about exposure to radiation during LDCT testing. Of the 414 participants, 50% were current smokers. After receiving information on the benefits of the test, 95.1% stated an intention to undergo screening; this decreased to 81.6% after they received information on the harms of the test. The average decrease in intention rate was 35.3%. Smoking status, household income, and education level were not associated with lowered intentions to undergo lung cancer screening. Participants who were older than 60 years old (OR=0.56; 95% CI= 0.33-0.96) and those with less concern for radiation exposure (OR=0.56; 95% CI=0.36-0.89) were less likely to lower their screening intentions. The results of this study suggest that there is a need to educate both non-smokers and former smokers on the harms of lung cancer screening.

This study aims to provide the basic data for coffee intake and health promotion by examining the conditions in which Korean adults consume the most coffee. The study used raw data from the second year of the 7th National Health and Nutrition Examination Survey (2017), and 3,325 subjects who were 19 years of age or older and who were not missing the required values. This number used as the average amount of coffee drank per day in the past year is at least one cup. In order to identify factors that affect coffee intake, the model included general characteristics such as gender, age, household income, education level, occupation, health behaviors such as smoking, drinking, high intensity and moderate intensity exercises, walking, physical activity during work and leisure, sleep time, stress and depression. The results showed that coffee intake was lower among women than men, coffee intake was higher for people 40-64 years than people 20-39 years old, physical occupations rather than non-physical occupations, smokers rather than non-smokers, and for high stress rather than low stress in life. Subjects with these factors are considered to be at risk of excessive caffeine intake from coffee. The risk group of this study should be studied for the effect of excessive consumption of coffee on personal health.

Purpose: The purpose of this study was to explore maternal physical activity support for preschool children. Methods: Survey methodology using a self-administered questionnaire was employed. Mothers with preschool children from a daycare center in Daejeon participated in the study. One hundred and fifty-six questionnaires were analyzed. Results: Mothers with preschool children showed a moderate level of physical activity support for their children. Significant factors affecting physical activity support of mothers were monthly household income (${\beta}$=.417, p=.002), maternal self-efficacy for physical activity support (${\beta}$=.231, p=.003), information for physical activity support (${\beta}$=.173, p=.022), and experience of education about physical activity support (${\beta}$=.237, p=.002). These variables explained 26.4% of the variance in physical activity support (F=7.628, p<.001). Conclusion: To improve maternal support for increasing physical activity of preschool children, maternal education and appropriate information should be provided to improve self-efficacy for physical activity support.

Objectives: This study investigated dietary and lifestyle factors associated with the weight status among Korean adolescents in multicultural families. Methods: This cross-sectional study analyzed 1,751 multicultural families' adolescents who participated in the 2017-2018 Korea Youth Risk Behavior Surveys. Information on dietary and lifestyle factors was self-reported using a web-based questionnaire and this information included breakfast and foods consumption, perceived health status, alcohol drinking, smoking, physical activity, and weight control efforts. Body mass index (BMI) was calculated based on the self-reported height and body weight (kg/㎡). Weight status was assessed according to the 2017 Korean National Growth Chart: underweight (weight-for-age <5^th percentiles), overweight (85^th≤ BMI-for-age <95^th percentiles), and obese (BMI-for-age ≥95^th percentiles). Multiple logistic regression analysis was performed to examine the dietary and lifestyle factors associated with weight status after adjustment for covariates. Results: Among Korean adolescents from multicultural families, the prevalence of overweight/obesity was 20.9%, whereas about 7% of adolescents were underweight. The weight status did not show differences according to gender, school level, area of residence, and household income. Compared to adolescents who did not have breakfast during the previous week, those who had breakfast 3-4 days/week and ≥5 days/week had a 42% (p=0.021) and a 37% (p=0.009) lower prevalence of overweight/obesity, respectively. The adolescents who frequently consumed carbonated soft drinks (≥5 times/week) showed an odds ratio (OR) of 1.69 (95% CI=1.01-2.83) for overweight/obesity relative to those adolescents who did not consume carbonated soft drinks. The OR of being underweight for adolescents who ate fast food ≥3 times/week was 1.97 (95% CI=1.04-3.71) compared to those adolescents who had not eaten fast food during the previous week. Conclusions: Dietary and lifestyle factors were associated with overweight/obesity as well as underweight among Korean adolescents in multicultural families. Our findings could be used to design and provide nutrition interventions for this specific population.

Drawing from the Korean Child and Youth Panel Survey (KCYPS), this study examined the changes in romantic relationship engagement among Korean adolescents across the country over a three-year period and the effects of the individual, familial, and school characteristics on the experience. Panel logit analysis showed that Korean adolescents were more likely to be engaged in a romantic relationship as they became older. Male adolescents were more likely than their female counterparts to have a romantic partner. The higher scores of self-esteem increased the likelihood of adolescents to be in a romantic relationship. On the other hand, having an opposite-sex sibling, the level of parental warmth, and annual household income did not have a significant relationship with the chance of romantic relationship engagement. On the contrary, all school-related variables were statistically related to the odds of being in a romantic relationship. Going to a sex-mixed school increased the odds, whereas academic adjustment and conformity to school rules decreased the likelihood. In addition, the positive relationships with schoolmates and teachers were associated with a higher chance of having a romantic partner. Based on these findings, the implications, limitations, and future research directions were also suggested.
