Background: Overweight, obesity, and cardiovascular disease risk factors are prevalent among firefighters in some developed countries. It is unclear whether physical activity and cardiopulmonary fitness reduce cardiovascular disease risk and the cardiovascular workload at work in firefighters. The present study investigated the relationship between leisure-time physical activity, cardiopulmonary fitness, cardiovascular disease risk factors, and cardiovascular workload at work in firefighters in Hong Kong. Methods: Male firefighters (n = 387) were randomly selected from serving firefighters in Hong Kong (n = 5,370) for the assessment of cardiovascular disease risk factors (obesity, hypertension, diabetes mellitus, dyslipidemia, smoking, known cardiovascular diseases). One-third (Target Group) were randomly selected for the assessment of off-duty leisure-time physical activity using the short version of the International Physical Activity Questionnaire. Maximal oxygen uptake was assessed, as well as cardiovascular workload using heart rate monitoring for each firefighter for four "normal" 24-hour working shifts and during real-situation simulated scenarios. Results: Overall, 33.9% of the firefighters had at least two cardiovascular disease risk factors. In the Target Group, firefighters who had higher leisure-time physical activity had a lower resting heart rate and a lower average working heart rate, and spent a smaller proportion of time working at a moderate-intensity cardiovascular workload. Firefighters who had moderate aerobic fitness and high leisure-time physical activity had a lower peak working heart rate during the mountain rescue scenario compared with firefighters who had low leisure-time physical activities. Conclusion: Leisure-time physical activity conferred significant benefits during job tasks of moderate cardiovascular workload in firefighters in Hong Kong.

Purpose: This study was conducted to examine the personal and social environmental factors affecting leisure time physical activity (LTPA) among adults living in rural communities. Methods: A cross-sectional study was conducted with a convenience sample of 282 adults living in three rural towns of Chungcheongbuk province. Leisure time physical activity was assessed through the Korean version of the Global Physical Activity Questionnaire (GPAQ), and social influence and social cohesion of social environment were assessed using reliable and validated measures. Multiple logistic regression analysis was conducted to explore personal and social environmental factors associated with LTPA. Results: The overall prevalence of leisure-time physical activity (LTPA) was 40.0%. Multiple logistic regression analysis showed that LTPA participation was associated with gender (OR=2.60, 95% CI=1.47-4.58), healthy eating (OR=1.15, 95% CI=1.01-1.31), unhealthy eating (OR=0.70, 95% CI=0.53-0.93) and social influence for physical activity (OR=1.11, 95% CI=1.03-1.20). However, social cohesion was not correlated with engaging in LTPA. Conclusion: Both personal and social environmental factors are associated with LPTA among rural adults living in Eup-Myen regions. Interventions to promote LTPA would likely benefit from considering healthy dietary intake and social influence for physical activity.

Objectives: This study aimed to examine the association between sitting time and BMI-defined low weight and overweight/obesity in Korean adolescents. Methods: Data were from Adolescent Health Behavior Online Survey (KYRBS) in 2015 including 63,345 adolescents aged 12-18 years. The analysis investigated low-weight and overweight/obesity odds ratio(OR) according to study sitting time and leisure sitting time adjusted for sex, school grade, social-economic status(SES), physical activity and sleeping time. Results: After adjusting for sex, school grade, SES, physical activity and sleeping time, study sitting time and leisure sitting time were not significantly associated with low-weight. However, leisure sitting time was positively associated with overweight/obesity. Conclusions: Health program to less sitting time should be established with consideration for differences in risk according to sex, age, SES and active leisure time through the school physical class should be provided to adolescents. Additionally, strategies to promote healthy weight are required to integrate sitting time, physical activity and sleeping time in Korean adolescents.

This study examined the relations of educational level and life-style behaviors to the obesity. A total of 507 male adults aged 30 - 50 years completed the self-reported questionnaires. Educational level was used for measuring socioeconomic status. Activity at work, leisure-time activity and TV watching were measured for life-style behaviors related to physical activity, and some demographic and family history of disease as well. Subjects were categorized as obese when BMI was equal to or over 25kg/$m^2$, in which 19.7％ resulted obesity. Using multivariate logistic regression, the association between the measured factors and obesity was assessed. The odds ratios (OR) for risk of obesity did not differ with either age or monthly income. Subjects who completed high school (OR = 0.36; 95％ CI = 0.20 - 0.66) or university (OR = 0.34; 95％ CI = 0.16 - 0.71) had lower risk of obesity than those with education below middle school. Those with moderate activity level at work (OR = 0.41; 95％ CI = 0.24 - 0.72) showed lower risk of obesity than in inactive ones. The subjects watching TV more than 3.5 hr/day presented higher risk of obesity (OR = 2.46; 95％ CI = 1.28 - 4.74), compared with those watching TV less than 1.5 hr/day. The higher risk of obesity observed in high level of leisure time activity than in low one was considered due to that physical activity at work and leisure-time might counteract each other. Educational level and activity at work or leisure-time activity or TV watching were jointed and categorized, and then OR for obesity was estimated. The extent of obesity risk at a given level of each work activity or leisure-time activity or TV watching was different depending the educational level, which was significantly high when educational level was below middle school. Educational difference had no effect on activity level at work. However, higher educational attainment increased the leisure activity and reduced TV watching (p＜0.05), indicating that low education tended to contribute to more sedentary life-style. The findings of this study is concluded that low education was related to obesity in adult males, and its relation can partly be explained through acquiring inactive life-style behaviors. Individuals with low education might be more susceptible to the risk factors of obesity.

본 연구는 40세 이상 중년의 남자 근로자 253명을 대상으로 신체 적합도 및 여가중 신체 활동과 혈중 지질 중 심혈관질환 발생에 특히 중요한 혈중 총콜레스테롤 값, HDL 콜레스테롤 값 및 총콜레스테롤/HDL 콜레스테롤 비와의 관련성을 알아 보기 위하여 시도된 단면조사연구이다. 단순분석에서 혈중 총콜레스테롤 값과 유의한 상관 관계가 있는 변수는 신체 적합도(r=-0.27), 비만지수(r=0.27)였다. 여가중 신체 활동은 총콜레스테롤 값이 170mg/dl 이상군에서만 총콜레스테롤 값과 유의한 상관관계(r= -0.20)가 있었다. HDL 콜레스테롤 값과 유의한 상관관계가 있는 변수들은 신체 적합도(r=0.15), 비만지수(r=-0.22)및 1주간 음주량(r=0.14)이였다. 총콜레스테롤/HDL 콜레스테롤 비와 유의한 상관관계가 있는 변수들은 신체 적합도(r=0.23), 비만지수(r=0.32), 총흡연지수(r=0.13), 1주간 음주량(r=-0.13) 및 야채 선호도(r=0.13)이었다. 신체 적합도는 안정시 맥박수와 중등도의 상관관계(r=-0.66)가 있었고, 여가중 신체 활동(r=0.19)및 비만지수(r=-0.18)와도 유의한 상관관계가 있었다. 다중회귀분석(Multiple linear regression) 결과 혈중 총콜레스테롤 값과 유의한 관련성을 보이는 변수는 신체 적합도(beta=-0.23)와 비만지수(beta=0.18)이었다. HDL 콜레스테롤 값과 유의한 관련성을 보이는 변수는 비만지수(beta=-0.25)뿐이었다. 총콜레스테롤/HDL 콜레스테롤 비와 유의한 관련성을 보이는 변수는 비만지수(beta=0.30)와 신체 적합도(beta=-0.16) 및 야채선호도(beta=0.14)이었다. 결론적으로 중년 남성 근로자들에서 신체 적합도는 비만지수와 함께 혈중 총콜레스테롤 값, HDL 콜레스테롤 값, 총콜레스테롤/HDL 콜레스테롤 비의 중요한 관련 요인이었다. 여가중 신체 활동은 혈중 총콜레스테롤 값이 170mg/dl 이상인 군에서만 혈중 총콜레스테롤 값과 관계가 있었고, 신체 적합도와는 관련성이 유의하지만 크지 않았다. 따라서 신체 적합도가 여가중 신체 활동보다 혈중 지질 농도의 더 중요한 관련요인이며, 앞으로 신체 활동에 관련된 역학적 연구에서 신체 적합도가 독립적이고 중요한 요인으로 추가되어야 할 것이다.

Purpose: The purpose of this study was to examine the effects of physical activity on glycemic control among Koreans with type 2 diabetes. Methods: A total of 215 patients with type 2 diabetes (82 male and 133 female) were recruited (mean age = $59.0{\pm}9.7$ years). The amounts of physical activity was assessed using the physical activity scale for elderly (PASE). Fasting blood glucose (FBG), Hemoglobin A1c ($HbA_1c$), and 2 hours post-prandial glucose (2hrPG) were measured. Results: The highest PASE score was housework-related physical activity. However, the amounts of walking was significantly higher in good FBG level (Z = 1.39, p=.041) and the amounts of leisure-time physical activity was higher in good HbA1 and 2hrPG level than in the poor glycemic control group (Z = 2.29, p<.001; Z = 1.99, p=.001). A logistic regression analysis showed that patients with leisure-time physical activity in the top quartile more likely presented with good glycemic control in $HbA_1c$, OR=3.84 (95% Confidence Interval (CI) = 1.65~8.95) and in 2hrPG, OR=4.06 (95%CI = 1.77~9.27), compared to patients in the lowest quartile. Conclusion: Leisure-time physical activity is effective for controlling the glucose levels, especially $HbA_1c$ and 2hrPG among type 2 diabetic patients. It is suggested that health providers need to more focus on providing aggressive recommendations on physical activity considering physical activity patterns by individuals.

Background: The present study investigated the association between two domains of physical activity (occupational physical activity [OPA] and leisure-time physical activity [LTPA]) and sleep duration. Methods: We investigated 3,421 paid workers from the Korea National Health and Nutrition Examination Survey, 2014-2015. Sleep duration was categorized into three categories (short for less than 5 h, optimal for 5-9 h, and long for more than 9 h). OPA and LTPA were defined in terms of answers to relevant questions. Odds ratios were calculated for sleep duration according to each physical activity domain using multinomial logistic regression models. Results: There were 464 subjects (13.6%) who showed short sleep duration, and 169 subjects (4.9%) who showed long sleep duration. Prevalence of OPA and LTPA was higher in male workers than in female workers (for OPA: 3.67% and 1.76%, respectively, p = 0.0108; for LTPA: 16.14% and 6.07%, respectively, p < 0.0001). The odds ratio of OPA for long sleep duration in female workers was 3.35 (95% confidence interval, 1.37-8.21). Otherwise, LTPA was not associated with sleep duration in female paid workers, nor both physical activity domains in male paid workers. Conclusion: Female paid workers with work-related physical activity were at risk of oversleeping. These findings also suggested that physical activity has distinct associations with sleep duration according to the physical activity domains and sex.
