Purpose: The purpose of this study was to identify the Health Promotion Life Profile of normal-weight and obese children, and factors related to obesity in elementary school children, and provide basic data for the development an obesity management program for these children. Method: The survey participants were 878 fourth to sixth grade elementary school children in Gwangju. $x^2$-test, t-test, ANOVA and multiple logistic regression with the SPSS program were used to analyze the collected data. Results: The Health Promotion Life Profile showed significant differences between normal-weight and obese groups according to food habits (t=3.305, p= .001) and exercise habits (t=-4.065, p=< .001). The Health Promotion Life Profile of obese children was also significantly different according to interest in weight control (F=3.044, p= .050), regular breakfast (F=3.699, p= .014), regular meals (F=6.868, p= .002). The multiple logistic regression analysis, showed that factors in obesity were significantly different according to gender, interest in weight control, fast eating, overeating and predilection for some food. Conclusion: The results of this study suggest that items on Health Promotion Life Profile such as food habits and exercise habits should be included in education programs to prevent obesity in elementary school children.

Background: Postoperative nausea and vomiting (PONV) is one of the most common postoperative complications. Despite this, few papers have reported the incidence and independent risk factors associated with PONV in the context of oral and maxillofacial surgery (OMFS). Therefore, we sought to determine the incidence of PONV, as well as to identify risk factors for the condition in patients who had undergone OMFS under general anesthesia. Methods: A total of 372 patients' charts were reviewed, and the following potential risk factors for PONV were analyzed: age, sex, body mass index, smoking status, history of PONV and/or motion sickness, duration of anesthesia, amount of blood loss, nasogastric tube insertion and retention and postoperative opioid used. Univariate analysis was performed, and variables with a P-value less than 0.1 were entered into a multiple logistic regression analysis, wherein P-values < 0.05 were considered significant. Results: The overall incidence of PONV was 25.26%. In the multiple logistic regression analysis, the following variables were independent predictors of PONV: age < 30 years, history of PONV and/or motion sickness, and anesthesia duration > 4 h. Furthermore, the number of risk factors was proportional to the incidence of PONV. Conclusions: The incidence of PONV in patients who have undergone OMFS varies from center to center depending on patient characteristics, as well as on anesthetic and surgical practice. Identifying the independent risk factors for PONV will allow physicians to optimize prophylactic, antiemetic regimens.

Injuries and infectious diseases have been the most important public health problems since the beginning of human life. Injuries result in death of about 30,000 people each year in South Korea. In terms of years of life lost, injuries are considerably more costly than either heart disease or cancer. In terms of cost - both the direct costs of care and the indirect costs to individuals, families, and societies of a diminished life-injuries are among the most expensive of all social problems. The main purposes of this study are (1) to describe the outcomes as well as treatment process of brain injured patients and (2) to identify the factors impacting on length of stay during hospitalization and hospital fees. The research method used in this study was to review the medical records of five hundreds brain injured cases using systemic random sampling. The multiple logistic regression was administered to identify the factors impacting on the outcomes. The results are as follow : (1) the consultation .ate was found to be 72.9% while referral rate was 11.2%; (2) nearly 30% of the respondents were hospitalized over 30 days; (3) multiple logistic regression analyses revealed that the determinants influencing LOS were number of consultations, number of lab tests, and surgery; (4) the determinants of hospital fee were severity of brain injury, gender of patients, number of consultations, number of lab tests, and surgery.

The depression of the elderly decreases satisfaction in life and is also an important risky factor of their suicide. The subjects of the study were 615 males and 904 females aged above 65 who had the 2008 Korea National Health and Nutrition Examination Survey on the relations between presence of spouses and depression given by the Korea Center for Disease Control and Prevention. Through a chi-square test and a multiple logistic regression, the relations between general characteristics, contraction, health characteristics and depression were analysed. As a result of the multiple logistic regression for which age, family income, subjective health status, presence of activity limitation and stress were revised, the odds ratio of the males without spouses was 2.37(95% CI 1.03-5.45), which indicates that they had more depression than female subjects. However, for the female subjects, there were no relations between presence of spouses and depression.

Objectives : This study was purposed to estimate prevalence of upper extremity musculoskeletal symptoms, level of occupational stress and their relationship among dental hygienists. Methods : This questionnaire study was performed during May to October 2010 with 317 dental hygienists worked in Busan and Gyeongsangnam-do recruited as study population. The occupational stress and upper extremity musculoskeletal symptoms were accessed using questionnaire of the Korean Occupational Stress Scale and musculoskeletal symptoms from the Korea Occupational Safety Health Agency. Data analysis was performed with the descriptive analysis, chi-square test, and multiple logistic regression analysis using SPSS(ver 19.0K)program. Results : The prevalence of upper extremity musculoskeletal symptoms and the level of occupational stress were 79.2% and $52.67{\pm}4.86$ in dental hygienists. By multiple logistic regression analysis, job insecurity(OR=2.86, 95% CI: 1.38-5.94 in stress high risk group; reference-stress low risk group) and organizational system(OR=3.32, 95% CI: 1.55-7.08 in stress high risk group; reference-stress low risk group) were associated with upper extremity musculoskeletal symptoms in dental hygienists. Conclusions : The overall prevalence of upper extremity musculoskeletal symptoms and level of occupational stress in dental hygienists were relatively high and some sub-scales of occupational stress were related with upper extremity musculoskeletal symptoms. Not only previously reported risk factors of musculoskeletal symptoms but also occupational stress should consider to prevent and improve upper extremity musculoskeletal symptoms in dental hygienists.

Objectives: The objective of this study was to investigate the possible effects of environmental cadmium (Cd) exposure on of bone mineral density (BMD) levels. Methods: A total of 171 residents around abandoned mines in Chungcheongnam-do were surveyed in 2008-2011. Urinary Cd and BMD were analyzed by atomic absorption spectrometry and Dual-Energy X-ray absorptionmetry, respectively. Osteoporosis and osteopenia were defined by T-scores set by the WHO; Tscore ${\geq}$ -1.0, normal; -1.0 > T-score > -2.5, osteopenia; and T-score ${\leq}$ -2.5, osteoporosis. Logistic and multiple linear regressions were applied to estimate the association between U-Cd levels and BMD. Results: The U-Cd geometric mean of 171 Koreans was 2.79 ${\mu}g/g{\cdot}cr$. The U-Cd concentration was significantly higher among women (2.98 ${\mu}g/g{\cdot}cr$) than men (2.39 ${\mu}g/g{\cdot}cr$). With the multiple regression model, the BMD was influenced by U-Cd, BMI, and monthly income. With the logistic regression model, osteoporosis was associated with U-Cd levels (OR = 3.239, 95% CI = 1.770-5.927). Conclusions: We conclude that exposure to cadmium is associated with an increased risk of osteoporosis.
