PURPOSE: This study was done to examine differences in the factors affecting Hwa-byung symptoms in middle-aged men and women. METHOD: There search design for this study was a descriptive survey design using a convenience sampling. Data collection was done using self-report questionnaires with 381 middle age people (169 men and 212 women) in Seoul and G city. ANOVA, t-test, Pearson correlation coefficients and stepwise multiple regression were used to analyze the data with SPSS Win 18.0 Program. RESULTS: There were significant differences in Hwa-byung symptoms and life stress between men and women. However anger rumination and mood states were not significantly different by gender. In multiple regression analysis, mood states, religion, and employment were significant predictors and explained 36% of Hwa-byung symptoms for men. In women, mood states, life stress, anger rumination and employment were significant predictors and explained 41% of Hwa-byung symptoms. CONCLUSION: Findings of this study provide a comprehensive understanding of Hwa-byung symptoms and related factors between men and women in Korea. However, further study with a larger random sample from various living environment is necessary.

PURPOSE: This study was done to identify the relationship among bone mineral density (BMD), body composition and osteoporosis self-efficacy and to identify predictors of BMD in female nursing students. METHOD: Participants were 154 nursing students. Osteoporosis self-efficacy was determined by a self-report questionnaire. BMD was measured by ultrasound bone densitometry and body composition by a body composition analyzer. Data were collected between April 1 and 27, 2013 and analyzed using descriptive statistics, ANOVA, Scheffe test, Pearson correlation coefficient, and multiple regression with SPSS 18.0. RESULTS: Mean BMD at the calcaneus site was 0.58+/-1.31 (T-score). Incidence of osteopenia was 11.7%. Percentage of body fat (PBF)-defined obesity had higher prevalence than body mass index (BMI)-defined obesity. BMD had significant positive correlations with skeletal muscle mass (r=.226, p=.005) and fat free mass (r=.225, p=.005). The factor predicting BMD was skeletal muscle mass with 4.7% of explained variance. CONCLUSION: Study results indicate that of body composition components, skeletal muscle mass is the prime predicting factor for BMD. Thus to promote healthy bones, it is important to strengthen the muscles using a program, based on balanced development of all muscles.

PURPOSE: This study was done to examine factors affecting cancer preventive behavior in middle-aged people. METHOD: The research design for this study was a descriptive survey design using convenience sampling. Data collection was done using self-questionnaire with 203 middle-aged people in Seoul and G city. Data were analyzed using t-test, ANOVA, Pearson correlation coefficients and stepwise multiple regression with the SPSS Win 20.0 Program. RESULTS: The mean score of cancer preventive behavior was 3.43+/-.14 out of 5. Cancer preventive behavior showed a significantly positive correlation with knowledge about cancer (r=.24, p<.001). In the multiple regression analysis, gender, perceived health status and knowledge about cancer were significant predictors and explained 14.5% of cancer preventive behaviors. CONCLUSION: Findings of this study allow a comprehensive understanding of cancer preventive behavior and related factors by middle-aged people. However, further study with a larger random sample from various living environment is necessary.

Background: and Purpose All young males in South Korea must undergo a physical examination for their participation in military service. We aimed to determine the prevalence rate (PR) of various neuromuscular diseases in young South Korean males using the data of exempted patients and soldiers. Methods: The number of males exempted based on specific items of physical examination corresponding to neuromuscular disease during 2011–2020 were obtained from the records of the Military Manpower Administration. The list of enlisted soldier patients who were discharged from military service due to neuromuscular diseases during 2011–2020 was obtained from the Armed Forces Medical Command, and their medical records were reviewed. Results: The PR of neuromuscular diseases was calculated among 948 identified males: 713 exempted males and 235 soldiers. The PRs of overall hereditary neuropathies, Hirayama disease (HD), myasthenia gravis (MG), and inherited muscle diseases in South Korean males in their early 20s were 8.34 (95% confidence interval [CI], 7.39–9.30), 5.54 (95% CI, 4.76–6.32), 2.97 (95% CI, 2.40–3.55), and 10.38 (95% CI, 9.31–11.46) per 100,000 persons, respectively.Among the enlisted soldiers, hereditary neuropathy with liability to pressure palsy was the most common neuromuscular disease, with a prevalence among the enlisted soldiers of 3.11 (95% CI, 2.42–3.80) per 100,000 persons. Myotonic dystrophy was the most prevalent myopathy, followed by facioscapulohumeral muscular dystrophy. Conclusions The 10-year PRs of hereditary polyneuropathies, HD, MG, and inherited muscle diseases in young South Korean males have been reported. These data could be valuable to understanding each neuromuscular disease in the young male population of South Korea.
