Regular exercise and a certain level of physical activity reduce the mortality rate in the elderly. The purpose of this study was to investigate the effect of physical activity on the prevention of fracture in the middle aged or older in Korea. The basic data are based on the Ansan and Ansung community cohort studies of the Korean Genome and Epidemiology Study conducted by the Korea Centers for Disease Control and Prevention in 2001, and the fracture data from the third survey in 2005 to the sixth survey in 2011. The physical activity of the aged in the 40s was mostly distributed in the World Health Organization (WHO) recommended range of 7.5 to 30.0 metabolic equivalent·hr/wk, and the activity was gradually divided into the low and high groups in the 50s and 60s. In the 60s, the risk of fracture was reduced to 0.63 times compared to that of the 50s when physical activity was the recommended level (odds ratio, 0.63; p<0.001). For Korean adults, there was no significant difference in fracture incidence according to the amount of physical activity in the middle-aged people. However, for the elderly aged 60 and over, the risk of fracture decreased when the WHO recommended level of activity was performed, and the risk increased when less or more activities were performed.

청소년기의 심리적 발달에는 환경의 역할이 중요하게 여겨져 왔으며, 그 중 형제자매의 역할과 출생순서가 큰 영향을 미칠 것이라 생각되어 왔다. 본 연구는 10차(2014년) 청소년건강행태온라인조사 통계 자료를 이용하여 우리나라 청소년의 출생순서에 따른 신체활동, 스트레스 정도와의 연관성을 알아보는 것을 목적으로 수행되었다. 첫째군보다 둘째이하군에서 더 많은 신체활동을 하였으며 자신이 경제적으로 낮은 위치에 있고 학업 성적이 좋지 않았으며 음주경험과 흡연경험 또한 높았다. 그러나 다변량회귀분석 결과 둘째이하군에서 스트레스나 자살시도가 높지 않았다. 청소년시기에 가정과 학교에서 출생순서에 따라 스트레스 관리전략을 차별화한 중재연구가 필요할 것이다. Backgound: A number of studies have documented relationship between various individual outcomes and birth order. This study sought to investigate the relationship between adolescents health behavior, stress and birth order. Methods: The data used in this study were obtained middle and high school students who replied to the 10th Korea Youth Risk Behavior Web-based Survey (KYRBWS) administered in 2014. We investigated the associations between health behavior, stress and birth order using multivariable logistic regression analysis controlling with age, height, weight, father’s education, mother’s education, economic status, academic status, sleep duration, sitting time, self-perceived health status, self-perceived happiness, depression mood, suicide idea, suicide plan, suicide attempt, drinking experience, smoking experience. Results: The distribution of first-born was 45.5% and later-born was 54.5%. In multivariable logistic regression the later-born replied higher portion of vigorous physical activity 3 days per week and strength exercise 5 days per week. And later-born replied lower economic status, lower academic performance and higher prevalence of drinking experience, smoking experience. Later-born they had more stress than first-born, but after adjusted for variable factors in multivariable logistic regression, birth order had no relationship with stress significantly. Conclusions: This study offers data for the development of intervention programs to adolescent related to birth order, and further study is necessary in order to clarify adolescent’s relationship between birth order and stress and individual outcomes.

Background: This study is aimed at finding out the relationship between long working hours, one of major job stress elements, and hearing impairment in unexposed workers to occupational and environmental noise. Methods: This study was performed on 1628 regular, full-time wage workers between the age of 25-64 who indicated in the survey of having no experience of exposure to noise, normal otoscopic findings, and not suffering from diabetes based on the data from the fifth Korea National Health and Nutrition Examination Survey (KNHANES 2010–2012). The average working hours per week was categorized into 40 h and lower group, more than 40 to 48 h group, more than 48 to 60 h group, and more than 60 h group. The groups were defined as suffering from low or high frequencies hearing impairment if the average hearing threshold for 0.5, 1, 2 kHz or 3, 4, 6 kHz in both ears exceeds 25 dB based on the pure tone audiometry. The association between average weekly working hours and hearing impairment was analyzed using logistic regression after gender stratification. Results: The prevalences of low and high frequencies hearing impairment in male workers were 4.3 and 28.6 %, respectively, which were much higher than female’s prevalence of 2.7 and 11.1 %. For male workers, no significant association was found between average weekly working hours and low and high frequencies hearing impairment. For female workers, odds ratios (OR) of low and high frequencies hearing impairment were 4.22 (95 % confidence interval (CI) 1.09–16.27) and 4.49 (95 % CI 1.73–11.67), respectively, after controlling for several related factors, such as, age, Body Mass Index (BMI), socio-economic status, health-related behavioral, and occupational characteristics variables, in the final model in the group working more than 60 h compared to the group working 40 h and lower. In addition, a dose-response relationship was observed that ORs of low and high frequencies hearing impairment were increased according to increasing average weekly working hours. Conclusions: The association between long working hours and hearing impairment in both low and high frequencies was significant in Korean female workers with a dose-response relationship. Therefore, the law to change the culture of long working hours should be enacted in order to protect the workers’ health and improve the quality of life in Korean workers.

Background: Previous studies on the association between shift or night work and weight change have been focused on finding the risk of weight gain caused by shift or night work. In this study, we aimed to reveal the risk of weight gain and weight loss associated with night work by using a nationwide representative data. Methods: This study was performed on 1605 full-time wage workers between the age of 20 and 69 based on the fifth Korea National Health and Nutrition Examination Survey (KNHANES 2010–2012). The association between night work and involuntary weight change in the previous year was divided into the categories of weight gain and weight loss and studied with modifications in socio-demographic variables, health behavior-related variables, and occupational characteristic variables. Results: The participants working in night work accounted for 10.6 % of total study participants (male; 11.9 %, female 7.4 %). Workers who worked more than 48 hours per week on average accounted for 41.6 % of the total study participants (male; 46.3 %, female 29.1 %). Odds ratio (OR) of weight loss associated with night work in male workers was 0.34 (95 % confidence interval (CI) 0.16–0.76) after controlling for several related factors. OR of weight loss associated with night work in female workers with long working hours was 1.95 (95 % CI 0.47–80.86) and that of weight gain was 2.83 (95 % CI 0.12–69.83) after adjusting associated factors. Conclusions: In this cross-sectional study with national representative sample, night work may lower the risk of weight loss in male workers and induce weight change (weight loss or weight gain) in female workers with long working hours. Therefore, future studies with cohort study design for night workers are needed to reveal the mechanisms and health effects of weight change associated with night work and establish proper management solutions with health and labor policies for Korean night workers.

Background: This study was aimed at finding out the exposure level of bisphenol A (BPA), a well-known endocrine disruptor, in relation to dietary factors using a data representing the Korean general population. Methods: This study was performed on 5402 adults aged 19 years and older based on the Second Korean National Environmental Health Survey (KoNEHS 2012–2014). The data analyzed urinary BPA concentration in relation to socio-demographic variables, health behavior-related variables, and dietary factor-related variables. Odds ratio (OR) was calculated through a logistic regression analysis after dividing the participants into high BPA exposure group and low BPA exposure group based on the top 75 percentile concentration. The logistic regression analysis was carried out considering the appropriate sample weight, stratification, and clustering of the second KoNEHS sample design. Results: The group drinking bottled water at home and the group using zip-top bags/plastic bags showed significantly higher urinary BPA concentration in female. OR tends to increase as the intake frequency of frozen food increased and OR of frozen food consumption of more than once a week was 1.48 (95% confidence interval (CI) 1.02–2.24) for male and the group drinking bottled water showed significantly higher OR of 1.45 (95% CI 1.06–2.17) after adjusting the related factors for female. Conclusions: BPA levels were high in female using bottled water and in male consuming frozen food, and therefore bottled water and frozen food need to be avoided to reduce BPA levels.

Objectives: This study was conducted to determine the number of hours worked per week by full-time wage workers by using the data of the Korean Labor and Income Panel Study (KLIPS), which represents the domestic urban area household, and to determine the association between weekly working hours and the level of self-rated health. Methods: We used data from the 11th KLIPS conducted in 2008. The subjects of this study were 3,699 full-time wage workers between the ages of 25 and 64 years. The association between weekly working hours and self-rated health was analyzed considering socio-demographic characteristics, work environment, and health-related behaviors. Results: Among the workers, 29.7% worked less than 40 hours per week; 39.7%, more than 40 to 52 hours; 19.7%, more than 52 to 60 hours; and 10.9%, more than 60 hours per week. After controlling for socio-demographic variables, work environment-related variables, and health-related behavior variables, the odds ratio (OR) for poor self-rated health for the group working more than 40 hours and up to 52 hours was calculated to be 1.06 (95% confidence interval (CI), 0.89-1.27) when the group working less than 40 hours per week was considered the reference. The OR for the group working more than 60 hours was 1.42 (95% CI, 1.10-1.83) and that for the group working more than 52 hours and up to 60 hours was 1.07 (95% CI, 0.86-1.33). After stratification by gender and tenure, the OR of the female workers group and that of the group with a tenure of more than 1 year were found to be significantly higher than those of the other groups. Conclusions: This study showed that workers working more than 60 hours per week have a significantly higher risk of poor self-rated health than workers working less than 40 hours per week. This effect was more obvious for the female workers group and the group with a tenure of more than 1 year. In the future, longitudinal studies may be needed to determine the association between long working hours and various health effects in Korean workers.
