This study compared levels of health and dietary behavior practices and health beliefs according to the stage of weight loss behavior change of Korean male workers. A self-administered survey questionnaire was collected from 411 male adult workers residing in Seoul, Kyeonggi, Chungcheong region. Practices of health related behavior, including smoking, drinking, exercise, work related physical activity, and dietary behavior according to dietary guidelines were evaluated. In addition, the levels of perceived benefit, perceived barrier, perceived susceptibility, perceived seriousness, and perceived cue to action from the health belief model were measured according to the stages of weight loss behavior change. Significant differences in BMI, level of daily exercise, and practices of dietary behavior according to dietary guidelines were observed among stages of weight loss behavior change. Subjects who were in action/maintenance stage showed a more desirable level of health behavior and health belief model variables, except perceived barrier. Based on the findings of this study, it is suggested that subjects with different stages of behavior change need an appropriate specific nutrition education method and material for improvement of nutrition education efficacy.

Purpose: The aim of this study is to identify factors affecting elders' intention to participate in healthcare programs. Methods: This secondary data analysis used data of 390 elderly people who lived alone and were enrolled in the Visiting Health Care Center of H-city. In 2014, questionnaires were used to collect data about demographics, social activity, depression, frailty, and intention to participate in healthcare programs. The data were analyzed by descriptive statistics and multivariate logistic regressions. Results: Among the participants, 51.8% intended to participate in the offered healthcare programs. The strongest factor affecting the intention was gender. Women were 4.85 times more likely to participate in the programs than men. The women's intention was associated positively with increased levels of frailty. The men tended to participate in the program as they got older and as the level of frailty and the number of chronic diseases increased. Conclusion: Gender-specific public healthcare programs for vulnerable elders living alone should be developed to maximize their participation in the programs and to promote good health. The healthcare programs must be tailored to the levels of the patients' physical functions.

Purpose: This study examined the factors that affect suicidal ideation among Korean adolescents according to their family type. Methods: The data of the 2017 Korea Youth Risk Behavior Web-based Survey was used in this study. Out of 62,276, a total of 60,077 adolescents (51,367 adolescents from two-parent families and 8,710 adolescents from single-parent families) were included in the analysis. Results: This study demonstrated that the level of suicidal ideation of the adolescents in single-parent families was significantly higher than that of the adolescents in two-parent families. The factors that affect suicidal ideation among the two-parent family adolescents were gender, grade, economic status, academic performance, smoking, drinking, physical activity, subjective health status, subjective body image, subjective happiness, stress, and depression. The factors that affect suicidal ideation among the single-parent family adolescents included gender, grade, smoking, subjective health status, subjective happiness, stress and depression. Conclusion: Single-parent family adolescents are likely to have a higher level of suicidal ideation along with higher levels of depression and stress and lower levels of subjective health and happiness, compared to single-parent family adolescents. For this higher-risk group of suicidal ideation, more thoughtful attentions and proactive policies are needed to manage their mental health and stress in school and family situations.

Objectives: It is crucial to detect and prevent oral problems early. Older adults, in particular, should go for regular dental checkups to maintain a healthy oral environment. This study identified the factors affecting regular dental examinations and unmet dental needs in older adults. Methods: This study analyzed 3,362 older adults aged 65 or over using the data from the 7th Korean National Health and Nutrition Examination Survey (KNHANES). Frequency analysis was performed on general characteristics. In addition, chi-square tests were done to determine differences in regular dental checkups and unmet dental needs according to general characteristics. Logistic regression analysis was performed on factors influencing regular dental checkups and unmet dental needs. Results: Factors influencing regular dental checkups were statistically significant according to residential areas, level of education, household income, and levels of physical activity (p<0.05). Factors influencing unmet dental needs were statistically significant according to residential areas, level of education, private medical insurance, and levels of dental pain (p<0.05). Conclusions: National level policy strategies should be implemented to improve the oral health of older adults. These strategies should encourage regular dental checkups to effectively lower the rate of unmet dental needs.

The purpose of this study was two-fold. First, comparisons on the psychological and physical attributes of normal weight, overweight, and obese children were conducted. Second, the influence of BMI and physical fitness interaction on psychological adaptation in children with obesity was explored. Participants were 245 children between the ages of 9 and 13 years (64.5% males). Data on children considered overweight (n = 45) or obese (n = 78) were gathered from the Korean Obese Children's Physical Activity (KOCPA) projects. Normal weight children (n = 122) were recruited from two Seoul elementary schools. Psychological measurements included Weight Efficacy Life-style Questionnaire (WEL), Physical Self-efficacy Scale (PSES), Child Dietary Self-efficacy Scale (CDSS), Self-concept Inventory (SCI), and the Korean version of the Pediatric Quality of Life Intervention TM Version 4.0 Generic Core Scales (PedsQLTM4.0). BMI (kg/m2) and physical fitness (e.g., aerobic endurance, flexibility) were recorded by experts in exercise physiology. Results showed that children in the high BMI group reported poorer psychological adaption and demonstrated lower physical fitness when compared to the remaining groups. Compared to normal weight children, children considered overweight and obese were found to have lower physical self-efficacy, more negative self-concept, and poorer quality of life. Further, these children also had significantly lower physical fitness levels than their normal weight counterparts. Physical fitness was found to have a significant main effect on weight efficacy (WEL), physical self-efficacy (PSES), and quality of life (PedsQL) in children considered overweight or obese. A significant BMI-physical fitness interaction effect was found for self-concept (SCI) only. Children with higher BMI reported poorer self-concept regardless of fitness level whereas children with lower BMI and higher fitness reported more positive self-concept. Implications and limitations are discussed.

Trunk holding test (Sorensen test) appear to have more value than strength test in prediction the occurrence of low back pain. Electromyographic activity of trunk extensor muscles during these test may provide clues to the etiology of neuromuscular-based low back pain. This study investigated the difference in back muscle endurance between healthy adult men and women using surface electromyographic (EMG) power spectral analysis. Thirty hea1thy subjects (15 men and 15 women) performed an unsupported trunk holding test for 60 seconds. Recording surface electrodes were placed over the erector spinae medially and laterally at vertebral levels of $L_1$ and $L_5$. Slope of total frequency was evaluated using the MP100WSW Fast Fourier Transform spectrum analysis program. The slopes of all indices of back muscle fatigue, except right $L_5$, were significantly steeper in men than in women (p<0.05). Our results indicated that the trunk holding test using EMG power spectral analysis of erector spinae muscles is useful for the evaluation of fatigue rate of these muscles. Our results also showed a higher muscle endurance in healthy adult women than in men.

Objectives: In spite of the importance of green space for reducing obesity-related problems, there has been little exploration of whether access to green space (e.g., parks and recreational facilities) influences the obesity rate of adults in the United States. The purpose of the study was to investigate the relationships among accessibility of green space, obesity rates, and socioeconomic and demographic variables among adults living in the State of Indiana, United States. Methods: We conducted a secondary data analysis to investigate the relationships among accessibility to green space, obesity rates, and socio-demographic variables with employing Geographic Information System in order to measure the accessibility of green space. Results: This study found that accessibility of green space served as a strong predictor of reduced obesity rates among adults (β=-2.478; p<0.10). In addition, adults with higher education levels, as well as better access to green space, were found to have even lower obesity rates (β=-0.188; p<0.05). Other control variables such as unemployment rates, food security, and physical inactivity are additional factors that influence obesity rates among adults. Conclusions: Accessibility of green space may play an important role in facilitating physical activity participation and reducing obesity rates.

The purpose of this study was to confirm that regular physical exercise habit and calcium intake play a role in reducing the risk of cardiovascular disease, particularly to confirm that regular exercise is important in reducing serum lipid levels in postmenopausal women. Subjects were classified into regular exercise group(more than 3 times/wk, more than 30 min per exercise) and non-regular exercise group. A convenient frequency method was used to assess the nutritional intake of subjects. Anthropometric measurement such as body weight and height, and blood pressure were measured. There was no significant difference between non-regular exercise group and regular exercise group in energy intake and calcium intake. The total cholesterol and LDL-cholesterol concentrations in non-regular exercise group were significantly higher than those in regular exercise group. There were no significant correlations between age or weight with blood lipids and blood pressure in regular exercise group, while there were significant positive correlations between age or weight with blood lipids and blood pressure in non-regular exercise group. The levels of serum cholesterol, triglyceride, blood pressure and atherogenic index increased with age in non-regular exercise women. The blood pressure in low total Ca intake/plant Ca intake ratio group was significantly higher than that in high total Ca intake/plant Ca intake ratio group. There was a highly significant positive correlation between Ca intake and HDL-cholesterol in non-regular exercise women. And, there was a highly significant negative correlation between Ca intake and blood pressure in regular exercise women. The results suggest that increased habitual physical activity and calcium intake should be recommended by way of decreasing blood lipids and blood pressure in postmenopausal women.
