본 연구는 코로나19로 인해 증대된 좌업생활이 건강을 유지하기 위한 신체적 요인에 어떠한 영향을 미치는지 분석하고자 하였다. 연구 대상은 좌업생활을 주로 하는 사무직 여성으로 33명을 선정하였다. 집단 설정은 좌업생활 시간에 따라 고 좌업생활 집단 11명, 중 좌업생활 집단 11명 그리고 저 좌업생활 집단 11명으로 구분하였다. 측정변인인 최대산소섭취량과 초과산소소비량의 집단 간 유의한 차이는 나타나지 않았지만, 혈중 젖산의 수치는 운동직후(p<.05), 그리고 회복기 15분(p<.001)과 20분(p<.001)의 시점에서 유의한 차이가 나타났으며, 회복반응의 정도는 저 좌업생활 집단에서 더욱 원활한 회복의 경향을 나타내었다. 이와 같은 결과가 나타난 것은 좌업생활 정도에 따른 시간의 차이가 건강을 유지하기 위한 요인에게 영향을 줄 것이라 사료된다. 따라서 개인적 공간에서 많은 시간을 보내는 코로나19 상황에서도 좌업생활 시간을 최소화하는 것이 필요할 것이라 생각된다.

The work posture impose additional stress upon human workers so that it should be carefully considered in designing works. However, we have a lot of manufacturing plants which convert their standing workplace to sedentary one. To confirm the validity of that trend, the authors conducted an experimental study, and compared the results. The results of the EMG and the self-cognitive symptoms, in general, showed a correspondent trend that the sedentary work posture was rated more comfortable. At the beginning of the work, complaint of the lowerback was higher whereas that of the lower leg and the feet went higher as the time elapsed. If the weight of workpiece were heavier than 500g, increasing rate of bodily discomfort in the sedentary posture were greater than that of the standing posture. In the meanwhile, the standing posture was consistently superior to the sedentary posture in its performance. Thus, in conclusion, for a light assembly work, sedentary work posture would be recommendable because bodily discomfort would be larger irrespective of the small increase of performance increase.

Purpose: The purpose of this study was to investigate the combined influence of screen based sedentary behavior and sleep duration on obesity, depression, and suicidal ideation in Korean Adolescents. Methods: This cross sectional study used secondary data from the 2013 Adolescent Health Behavior Online Survey. A total of 27,929 high school students were included in the study. Logistic regression was used for analysis of the combined influence of screen based sedentary behavior and sleep duration on obesity, depression, and suicidal ideation. Results: Obesity was more prevalent among adolescents who had ${\geq}$ 4h of screen based sedentary behavior and <7h of sleep duration compared to the reference group, defined as < 2h of screen time and > 7h of sleep duration. Depression and suicidal ideation were more prevalent among adolescents who had 2-4h of screen based sedentary behavior and <7h of sleep duration compared to the reference group. Conclusion: Based on the results of this study, maintaining a low (< 2h) level of screen based sedentary behavior and appropriate sleep duration over 7 hours per day is essential for prevention of adolescent obesity, depression, and suicidal ideation.

There is a dearth of Korean studies on dehydration, one of the health risks for adult women. This study analyzed the subjects of the 2016~2018 National Health and Nutrition Examination Survey (KNHANES) to investigate the relationship between nutrient intake ratios and sedentary time in dehydrated women. Body mass index and waist circumference in the dehydrated group (DG) were significantly higher than the normal group (NG). Intake of other liquids in the DG was significantly higher than in the NG, but total water intake in the DG was significantly lower than in the NG. Compared to the 600 sedentary minutes or more per day group, the odds ratio of dehydration was significantly higher in the less than 300 sedentary minutes per day group (1.871 [95% CI: 1.579~2.215], P<0.001). Compared to the drinking over 6.0 cups of water per day group, the odds ratio of dehydration was significantly higher in the 3 cups or fewer per day (OR [95% CI] is 1.198 times [1.019 to 1.408], P<0.05), and 6.0 cups or fewer group (OR [95% CI] is 1.162 times [1.018 to 1.326], P<0.05). The results of this study showed that the total water intake was relatively lower in the ≥600 sedentary minutes per day group compared to the 300 sedentary minutes per day group, making them more vulnerable to dehydration. The nutrient intake ratios were higher in the dehydration group than in the normal group. In conclusion, emphasis should be placed on the importance of hydration and nutrition education for adult women in the workplace.

Purpose: This study examined the combined effects of sugar-sweetened beverage (SSB) consumption, screen-based sedentary behaviors, and sleep duration on adolescent obesity. Methods: It followed a cross-sectional study design and conducted secondary analysis on data from 20,497 high school students who participated in the 17th (2021) Korea Youth Risk Behavior Web-based Survey. This study underwent logistic regression analysis in complex sampling analysis. Results: The combinations of low and medium consumption of SSBs, excessive screen-based sedentary behaviors, and short sleep durations were associated with a 1.18 and 1.12 fold increased likelihood of obesity (95% confidence interval [CI]=1.03-1.35) and (95% CI=1.02-1.22), respectively. The combination of high SSB consumption, appropriate screen-based sedentary behaviors, and short sleep duration (adjusted odds ratio [aOR]=1.15, 95% CI=1.01-1.31) and high SSB consumption, excessive screen-based sedentary behaviors, and short sleep duration (aOR=1.40, 95% CI=1.16-1.69) were associated with obesity. Conclusion: Integrated and tailored programs considering combination patterns of SSB consumption, screen-based sedentary behaviors, and short sleep duration need to be developed for preventing adolescent obesity.

Objectives: To determine the relationships between physical activity (PA), the neighborhood environment support for PA, and social support for PA among Mexican-American women living in South Texas. The Enlace study was a randomized controlled trial that tested the effectiveness of a promotora-led PA intervention among low-income Mexican origin women (n=614) living in colonias. Methods: The dependent measures included accelerometer-measured average moderate to vigorous physical activity (MVPA) and sedentary breaks and the Community Health Activities Model Program for Seniors PA 41-item questionnaire. The independent measures included the Physical Activity and Neighborhood Environment Scale (PANES) and the 13-item Physical Activity Social Support (PASS) scale. Results: Enlace participants were on average 40.4 (standard deviation, 10.3) years old, born in Mexico (86.1%), and uninsured (83.1%). Adjusted linear regression results indicated that each 1-point increment in the PANES overall score was associated with 0.050 (p<0.001) unit increase in sedentary break and a -0.043 (p=0.001) unit decrease in sedentary break duration. Both PANES (${\beta}=0.296$; p=0.002) and PASS scores (${\beta}=0.076$; p<0.001) were associated with weekly average self-reported MVPA. Interaction effects were observed between PASS scores and accelerometer-measured frequency of sedentary breaks and sedentary time duration. Conclusions: The findings of this study indicate that the relationships between PA and built environment and social support are measure-dependent and suggest that reducing sedentary time in this population may require a closer assessment of social support for PA.

Objective: Patients with COPD have a lower overall quality of life than normal people. If patients with COPD do not regularly perform physical activities, their exercise capacity is reduced. It could lead to muscle loss, and negatively affect their general physical, social, and psycho-social status. The purpose of this study was to examine association with physical activity, sedentary life time and health-related quality of life in patients with COPD. Method: Of the total of 22,948 participants surveyed in Korean National Health and Nutrition Examination Survey (KNHANES 2013-2015), 8,626 participants were used for this study. Of these, under 40 years, over 80 years, missing values and abnormal values were excluded. Study variables included physical activity level, sedentary time and health-related quality of life variables. The physical activity level assessment tool was measured using International Physical Activity Questionnaire (IPAQ). Sedentary time referred to the amount of sitting time without moving the body. EQ-5D (Euro Quality of Life-5 Dimensions) was used as an index of health-related quality of life. Control variables were age, gender, income level, education level, marital status, comorbidity, smoking, BMI, cough, sputum, COPD severity. For this study, descriptive analysis, T-test, ANOVA and multivariate regression analysis were performed. Results: Of the 1,092 patients with COPD, 76.1% (n=831) were male and 23.9% (n=261) were female, while 39.0% (n=2,939) were male and 61.0% (n=4,595) were female in the comparison group without COPD. The COPD group with high level of physical activity showed a high level of EQ-5D scores ($0.9349{\pm}0.11$, p <0.001). Among patients with COPD, after adjusting for control variables, physical activity and sedentary time (physical activity level, Β=0.047, p <.001), (sedentary time, Β=-0.017, p <.05) were associated with health-related quality of life. Conclusion: Patients with COPD have a higher quality of life as their physical activity increases and the quality of life decreases as the time spent sitting increases. This study suggests that public health experts should consider improving COPD patient physical activity.

Purpose: Sitting time, smoking, and perceived stress strongly influence physical health independent of physical activity. However, the associations among perceived stress, sedentary behavior, and smoking are poorly understood. Therefore, we examined the relationships between sitting time, smoking, and perceived stress in Korean adults aged < 65 years. Methods: We analyzed data from the seventh National Health and Nutrition Survey. In this cross-sectional study, data from 6,890 Korean adults aged < 65 years were analyzed. Complex-sample logistic regression was used to examine the relationships between sitting time, smoking, and perceived stress. Results: The group with a high sitting time (≥ 8 h/day) and those who smoked had significantly higher odds of experiencing stress than the low sitting time (< 8 h/ day) and non-smoking groups (odds ratio: 1.88, 95% confidence interval: 1.42-2.50). Conclusion: Perceived stress was positively correlated with current smoking status and increased sitting time. High sitting time (≥ 8 h/day) and current smoking were associated with a higher risk of perceived stress in Korean adults aged < 65 years.
