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.

BACKGROUND/OBJECTIVES: Curfew due to the coronavirus disease 2019 (COVID-19) pandemic could influence health behaviors in people, especially in children, who can easily acquire unhealthy eating habits. This study aimed to investigate the effect of COVID-19 on weight, health behaviors including eating habits, physical activity, and sedentary behavior in children aged 6-15 years in Saudi Arabia. SUBJECTS/METHODS: We conducted a cross-sectional online survey that included 280 children aged 6-15 years in Saudi Arabia during the COVID-19 curfew. The survey included questions on sociodemographic characteristics, anthropometric measures, and health behaviors including eating habits, physical activity, and sedentary behavior. RESULTS: We observed a significant difference in the body mass index before and after the COVID-19 pandemic (P < 0.001). Children significantly tended to skip breakfast, along with a decreased intake of dairy products and fast food (P < 0.001). Moreover, children were less physically active and significantly tended to be involved in leisure screen-based activities, including watching TV and use of computer/games (P < 0.001). CONCLUSIONS: This study provides evidence for the negative influences of the COVID-19 curfew on health behaviors, including eating habits, physical activity, and sedentary behavior in children in Saudi Arabia.

The purpose of this study was to determine the effect of sedentary time on quality of life and oral health-related behaviors using the Korean National Health and Nutrition Examination Survey. A total of 19,983 data were analyzed using the IBM SPSS 25.0 program, and complex sample logistic regression analysis was performed to confirm the effect of sedentary time on health-related quality of life and oral health-related behaviors. As a result, the longer the sitting time, the worse the quality of life (p<.05). There was an increase in the number of cases of not brushing (p<.05). Also, as for dental treatment, the longer the sitting time, the more prophylactic treatment and periodontal treatment increased (p<.05). Therefore, it is judged that it can be used as basic data to improve the quality of life and increase oral health-related behaviors in consideration of the socio-demographic characteristics of prolonged sedentary time.

The purpose of this study was to analyze the patterns and interrelationships for meeting recommendations of physical activity, sedentary behavior, and dietary behavior in elementary school students. A cross-sectional design was used to assess 259 students ages 11 to 13 years. Physical activity (moderate to vigorous physical activity $\geqq$60min/day), sedentary behavior (viewing time for TV, computer, DVD, video, etc<3hr/day), and dietary behavior (servings of fruits and vegetables$\geqq$5times/day) were categorized into two levels: meeting recommendations or not meeting recommendations. Parents' health behaviors and home environmental variables were assessed with self-reported measures. Chi-squared tests and independent t-tests were conducted to compare anthropometric variables and the prevalence of students not meeting the recommendation for the three health behaviors. Comparison between males and females and logistic linear regression were used to determine the interrelationships of three health behaviors. 25.9% of students did not meet the physical activity recommendations. 15.4% did not meet sedentary behavior recommendations, and 41.7% did not meet dietary recommendation. Only 39.8% of students met all three recommendations, but 19.0% did not meet over two recommendations. Patterns that simultaneously did not meet two recommendations were: sedentary and dietary behavior in males (8.1%), and physical activity and dietary behavior in females (10.4%). Students who did not meet dietary recommendations were at greater risk of not meeting physical activity (OR 2.76; 95% CI 1.15 to 6.64), and sedentary behavior (OR 3.07; 95% CI 1.15 to 8.16) compared with students who did meet dietary recommendations. The findings of this study support not an independent behavior approach but a multiple behavior approach taking into account gender and interrelationships among the three behaviors.

Purpose: The purpose of this study was to investigate the effects of sedentary behavior on subjective health in Korean adolescents. Methods: This study is designed as a cross-sectional study. The study sample comprised of 60,040 middle and high school students primarily at the age of 12 to 17. Using data from the 14th (2018) Korea Youth Risk Behavior Web-based Survey, multiple logistic regression analysis was conducted. Results: The rate of engaging in sedentary behavior for less than 2 hours was 28.4% and for more than 4 hours was 28.2% in Korean adolescents. In the result from the logistic regression analysis, compared to engaging in sedentary behavior for 2 hours or less, the adjusted odds ratio was 1.15 for over 4 hours, with other factors controlled. Conclusion: It is necessary to actively develop and promote active leisure activities and limit excessive media exposure and supplementary learning for adolescents.

Purpose: This study aimed to comprehensively explore the associations of socioeconomic status, parenting style, and grit with children's health behaviors. Methods: This was a cross-sectional study of 1,040 parents and their children using data from the 2018 Korean Children's Panel Survey. Socioeconomic status was measured in terms of household income and subjective socioeconomic status. Parenting style and grit and were measured using 62 and 8 items, respectively. Health behaviors were measured by assessing healthy eating habits, physical activity, and sedentary behavior. Results: Higher household income (β=.07, p=.018) and high maternal levels of an authoritative parenting style (β=.20, p<.001) were associated with higher compliance with healthy eating habits among children. Higher grit was associated with a higher number of weekly physical activity days (β=.08, p=.028) and sedentary behavior for <2 hours (odds ratio [OR]=1.04, 95% confidence interval [CI]=1.01-1.07) in children. A maternal permissive parenting style was associated with sedentary behavior for >2 hours on weekdays (OR=0.43, 95% CI=0.27-0.69). Conclusion: We suggest that when planning interventions to improve children's health behavior, it is essential to adopt a multifaceted approach that avoids practicing a maternal permissive parenting style, promotes an authoritative parenting style, and incorporates strategies to increase children's grit.

Objectives: This study aims to determine the relationship between sedentary behavior and oral health factors in adolescents. Methods: Based on the data from the online survey on youth health behaviors, general characteristics, sedentary behavior was classified as practiced for less than 2 hours, and not practiced for more than 2 hours, and oral health was classified brush teeth after lunch, sealant, oral symptoms. The analysis methods were complex frequency analysis, complex chi-square test, and complex logistic regression analysis. Results: In case of brush teeth after lunch during the week, those who practiced it was 1,025 times higher than those who did not practice it, and in the case of oral symptoms practice was 0.915 times lower than not practice. As a result of adjusted general characteristics, for brushing teeth after lunch during the week, practice was 1,090 times higher than no practice. Conclusions: The relationship between sedentary behavior and oral health behavior and oral symptoms could be confirmed. Therefore oral health promotion programs according to sedentary behavior are needed to promote oral health for adolescents.

Purpose - Due to the lack of physical activities and the increase of sedentary behaviors such as screen time, the health condition for contemporaries has been deteriorating. This study is designed to investigate how the use of worktable or tools unfit for body and sedentary behaviors can exercise influence on muscular skeletal disease and how it has an impact on lowering work efficiency and the quality of life with the medium of the muscular skeletal disease. Research design, data, and methodology - The research has developed a questionnaire with 5 hypothesis. The questionnaires were also made by interview and E-mail. 350 copies of questionnaires were distributed and 315 questionnaire were used for the analysis as valid data responses. SPSS ver.22.0 were used and made Cronbach's and reliability test, correlation, Baron & α Kenny 3 step mediated regression analysis. Results - The research has found that living environment factors have positive effect on the occurrence of musculosketal disease. Particularly, repeated use of unfit worktable or tools has a positive effect on the muscular skeletal disorder. And sedentary lifestyle also has a positive effect on the disease. The musculoskeletal disease caused by living environment has a positive impact on lowering the work efficiency. This study has also showed that the muscular skeletal disease has mediated the relationship between the living environment factors and the decrease of work efficiency due to musculoskeletal disease. The musculoskeletal disorders can effect the decrease of the quality of life as well, for the decrease of work efficiency has a positive effect on lowering the quality of life. Conclusions - Sedentary lifestyles, the use of worktable unfit for body, and the repeated use of a tool have caused the increase of muscular-skeletal diseases, and reduction of productivity as well as the hight cost of medical treatment for our contemporaries. Understanding the cause of disease morbidity, finding ways to prevent the disease, and educating people about them would contribute not only to improvement of individual health but also to the advancement of welfare for all.

This study explores the influence of health behaviors and individual attributes on adolescent overweight and obesity using data from Wave II (Add Health). Structural equation model/ path analysis using maximum likelihood estimation was utilized to analyze the relationships of health behaviors and attributes with obesity. Results of the model reveal that the causal paths (adolescents' attributes and health behaviors) for overweight and obesity were different for African American and Caucasian adolescents. Generally, African Americans were more susceptible to overweight and obesity than Caucasians. Although increasing levels of vigorous physical activities lowers the risk for obesity among African American and Caucasian adolescents alike, low family SES and being sedentary were associated with overweight and obesity among Caucasians. No significant associations were found among African Americans. Increased hours of sleep at night relate positively with obesity among African Americans. These findings suggest important elements in the consideration of race in developing effective intervention and prevention approaches for curbing the obesity epidemic among U.S. adolescents.

The purpose of this study was to analyze the patterns and the interrelationships for meeting guidelines of three health behaviors including physical activity(PA), sedentary behavior(SB), and dietary behavior(DB) for Korean adolescents using 2007 KYRBS(Korea Youth Risk Behavior Survey) data. A cross-sectional design was used to assess 73392 middle-high school students. PA(moderate physical activity${\geqq}$5times/week, or vigorous ${\geqq}$3times/week), SB(watching TV, computer, DVD, video, etc. < 3 hr/day), and DB(servings of fruits ${\geqq}$1 times/day, or vegetables ${\geqq}$ 3 times/day) were categorized into two levels (meeting guidelines or not). Chi-squared tests were conducted to compare the prevalence of students not meeting these three health behaviors between boys and girls, and logistic linear regression was used to determine the interrelationships of three health behaviors. Students meeting guidelines for PA, SB, and DB were 31.0%(boys 42.6%, girls 18.0%), 74.7%(boys 75.4%, girls 74.0%), and 38.5%(boys 38.6%, girls 38.4%), respectively. In addition, there were significant differences between both genders for PA and SB (PA; $x^2(1)$=35175.11, p<.0001, SB; $x^2(1)$=19.44, p<.0001). Only 10.9% of students met all three guidelines and 12.4% did not meet all three. Pattern that simultaneously did not meet PA and DB were high in both boys(27.1%) and girls(37.2%). Students who did not meet DB were at greater risk of not meeting PA(Boys; OR 1.49, 95% CI 1.43 to 1.55, Girls; OR 1.42, 95% CI 1.34 to 1.50), and not meeting SB(Boys; OR 1.41, 95% CI 1.34 to 1.48, Girls; OR 1.36, 95% CI 1.29 to 1.43) compared with students who met DB. The findings of this study supported further evidence for the need of a multiple behavior approach considering gender and interrelationships among three behaviors.
