The purpose of this study is to examine Korean Youth’s physical activities, sedentary behavior, and condition of dietary behavior and its relationship to health related factors depending on sedentary activity patterns. Data from the 2016 Korean Youth Risk Behavior Web-based Survey were analyzed using SPSS 23.0 program. The condition of sedentary behavior show that although most of the time is spent sitting for academic purposes during the weekdays, time spent sitting down for other reasons were great as well. Female adolescents spend an average of four hours of their leisure time sitting down and had low level of practicing sedentary behavior. The relationship between sedentary behavior and physical activities showed a significance difference in walking, high-level exercise, strength exercise depending on the amount of sedentary behavior, and it also showed a significant difference in the participation of physical education class. Furthermore, adolescents’ subjective well-being, perception of happiness level, experience in depression, perception of stress, recovery from sleep showed a signficiant difference depending on their sedentary behavior. Those who practiced their sedentary behavior of less than two hours perceived to be healthy, felt more happy, experience in depression and perception of stress level were low. Those who practiced the guideline criterion of sedentary behavior of sitting down for less than two hours showed that they eat breakfast, fruits, vegetables, and milk, and rarely take in soft drinks, sweet drinks, and instant foods. Adolescents who follow a healthy diet behavior guideline perceive their health positively, feel more happy, recover exhaustion from sleep, and perception of stress level were low. Overall, the results above show that adolescents who practice the guideline criterion of sedentary behavior will have a positive influence in having a healthy diet behavior and will improve their physical activity level. 본 연구는 우리나라 여자 청소년들의 좌식행동 실태를 파악하고 건강요인과의 관련성을 탐색해 보고자 실시하였다. 연구자료는 청소년건강행태 온라인조사의 2016년도 원시자료를 사용하였으며, 모든 자료는 SPSS 23.0 프로그램을 이용하여 분석하였다. 본 조사대상 여자 청소년의 경우 주중에는 학습목적으로 앉아서 보내는 시간이 대부분이었으나 주말의 경우 학습이외 목적으로 앉아서 보내는 시간이 평균 4시간이상으로 여가시간의 대부분을 앉아서 보내고 있는 것으로 나타났다. 한국인 좌식행동 지침 실천율이 매우 낮은 수준이었으며 좌식행동 양상에 따른 신체활동 실천 정도 및 학교체육활동 참여 정도에서도 유의한 차이를 나타내어 학습이외의 목적으로 앉아있는 시간이 많은 청소년들의 경우 신체활동 수준이 적으며 학교 체육활동에도 소극적으로 참여하고 있음을 알 수 있다. 청소년들의 주관적 건강, 행복인지수준, 우울감 경험, 스트레스 인지, 잠으로의 피로회복 정도 등의 건강상태도 좌식행동 양상에 따라 유의한 차이를 보였다. 좌식행동이 2시간미만으로 권고지침을 실천하는 학생의 경우 자신의 건강상태가 건강하고, 행복하다고 느끼는 비율이 높았고 우울감 경험 및 평상시 스트레스 인지율은 낮았다. 식이행동도 좌식행동 양상에 따라 유의한 차이를 나타냈다. 앉아서 보내는 시간이 2시간 미만으로 좌식행동 권고 지침을 실천하는 학생의 경우 아침식사, 과일섭취, 채소섭취, 우유 등을 많이 섭취하였으며, 탄산음료, 단맛음료, 패스트푸드 등 인스턴트 음식을 자주 먹지 않는 것으로 조사되었다. 건강 식생활 지침을 잘 이행하고 있는 학생들의 경우 자신의 건강상태에 대하여 긍정적으로 인식하고 있었으며, 행복하다고 느끼는 비율과 잠으로 피로회복의 충분도 역시 높았으며 평상 시 스트레스 인지율은 낮았다.

Background: Sedentary behavior is associated with several adverse health outcomes. Data on factors that influence sedentary behavior are lacking in Bhutan. This study examined factors associated with increased sedentary behavior in Bhutan, with a focus on exploring sex differences. Methods: Data of 2,796 adults from the nationally representative 2014 Bhutan STEP-wise surveillance (STEPS) survey were analyzed. Factors associated with sedentary behavior were identified using backward elimination multiple logistic regression analysis, disaggregated by sex. The analysis accounted for the complex survey design used in the primary survey. Results: The overall prevalence of sedentary behavior was 8.2%, with a higher proportion among women than men (10.3% vs. 4.9%). In the full sample, female sex, being single, high education and income, urban residence, inadequate physical activity, and high blood sugar were associated with increased odds of sedentary behavior. Among females, those who had high education and income, were single, physically less active, and urban residents were more likely to be sedentary. Self-employment was related to reduced odds of sedentary behavior among women and in the overall sample population. In males, being single, higher education level, and urban residence were associated with sedentariness. Conclusion: The findings suggest that interventions targeting females, especially those who are physically less active and from higher socioeconomic groups, urban residents, and those with hyperglycemia can potentially help reduce sedentary behavior and avert the associated detrimental impacts.

Evaluation of Daily Physical Activity and Sedentary Behavior

( Shigeho Tanaka ) 한국체육학회 2015 국제스포츠과학 학술대회 Vol.2015 No.1

Purpose: Physical activity (PA) consists of exercise and non-exercise PA, also termed non-exercise activity thermogenesis (NEAT). NEAT is much larger than that of exercise-induced EE, and varies substantially between individuals. In this lecture, the evaluation methods will be overviewed. Method: The doubly labeled water (DLW) method is an excellent method to use for measuring total energy expenditure (EE) in unrestrained humans under free-living conditions over about 2 weeks, with relatively high accuracy and precision. However, this method can only evaluate total EE and cannot provide day-to-day or minute-by-minute variations.]At present, several methods are used to measure EE in a field setting, i.e., behavioral observation, questionnaires, and physiological markers such as heart rate and motion sensors or activity monitors. Among them, questionnaires, pedometers and activity monitors have been frequently utilized, therefore will be focused. Result: Questionnaires can provide qualitative information, such as type and purpose of PA, that differs from that provided by objective methods. However, the accuracy of questionnaires to measure PA intensity and EE is not sufficient. On the other hand, activity monitors are objective, small, non-invasive tools for measuring PA intensity and EE. Most NEAT is non-locomotive activities, and NEAT, especially NEAT due to non-locomotive activity, is difficult to measure under free-living conditions. Therefore, accurate metabolic equivalents estimation for non-locomotive and sedentary activities is required in addition to estimates of locomotive activity. Activity monitors can be used to study patterns of activity across time (e.g., bout or break). A new generation of accelerometers will provide information on body posture and activity recognition to allow objective assessment of subjects` habitual activities. Step counts mainly reflect moderate intensity PA, rather than total PA or physical activity level. The relationship between step counts and total PA depends on sex, age, and occupation. Accurate estimation of sedentary activities is important, because many people spend almost 10 hours/day in sedentary behavior. The prediction accuracy of lower- intensity PA is generally poor. One possible reason is the low sensitivity of accelerometers. Predictive equations for sedentary behavior with high accelerometer sensitivity may improve prediction accuracy. Conclusion: NEAT consists of non-locomotive activities. Now we can accurately estimate MET even for some non-locomotive and sedentary activities. Novel approaches have recently been developed to provide information on body posture and activity recognition. Therefore, a new generation of accelerometers will provide a greater variety of more accurate information on human activity/behavior continuously and objectively, including sedentary behavior and light activities and the context of those behaviors. Such development will contribute to better personalized lifestyle interventions for health promotion and will facilitate a higher quality of research on PA and sedentary behavior.

Objectives: The maintenance of the postural balance is fundamental for the daily living activities, as well as for the practice of physical exercise. However, the aging process and sedentary behavior (i.e., large sitting time) lead to changes biological systems, impairing postural balance with consequent increased falls risk. On the other hand, physical activity practice is a protective factor against these trends. The aim of this study is to investigate the influence of physical activity profile and sedentary behavior on postural control in community-dwelling old adults. Methods: This is a cross-sectional study including 208 community-dwelling old adults, which were stratified as sufficiently or insufficiently physically active and with or without sedentary behavior. Then, they were grouped as follow: G1 (sufficiently physically active and without sedentary behavior), G2 (insufficiently physically active, but without sedentary behavior), G3 (sufficiently physically active, but with sedentary behavior), and G4 (insufficiently physically active and with sedentary behavior). Results: Stabilometric parameters (sway area, total length of center of pressure [CoP] trajectory, and the mean velocity of CP displacement) were obtained to evaluate the postural control. There was significant difference between G1 and G4 on mean velocity of CoP displacement (p < 0.05). Conclusions: The coexistence of sedentary behavior and insufficient physically active profile seem to impact negatively on postural control.

코로나19로 인한 좌업생활 증가에 따른 건강유지 요인 분석

신세영,진승모 한국융합학회 2022 한국융합학회논문지 Vol.13 No.4

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. 측정 변인인 최대산소섭취량과 초과산소소비량의 집단 간 유의한 차이는 나타나지 않았지만, 혈중 젖산의 수치는 운동 직후(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 purpose of this study was to investigate how the increased sedentary behavior due to COVID-19 on physical factors to maintain health. The subjects of the study were 33 office women who mainly lead a sedentary behavior. The group settings were divided into high sedentary behavior groups(n=11), middle sedentary behavior groups(n=11), and low sedentary behavior groups(n=11) according to the hours of sitting down living. There was no significant difference between the groups in the VO₂max and EPOC, the level of lactate in blood showed a significant difference immediately after exercise(p<.05) and at 15(p<.001) and 20(p<.001) minutes of recovery, and the degree of recovery was more smooth in the low sedentary behavior groups. These results suggest that the difference in time according to the degree of sedentary behavior will affect the factors for maintaining health. Therefore, it is considered necessary to minimize sedentary behavior time even in the COVID-19 situation where the time spent in a personal space increases.

OBJECTIVES: We examined trends in physical activity and sedentary behavior in Korean adolescents, and their association with socioeconomic position (SEP). METHODS: We used data from the Korea Youth Risk Behavior Survey, a nationwide study involving students aged 12-19 conducted between 2009 and 2021. SEP was assessed based on economic status, parental education attainment, and urbanization. Physical activity was categorized into vigorous physical activity, moderate physical activity, and muscle training, and sedentary time was also measured. We conducted the log-binomial regression to calculate prevalence ratios (PRs) and prevalence differences. RESULTS: Our analysis included a total of 593,896 students. We observed an increasing trend in physical activity, but a worsening trend in sedentary behavior. A positive association was found between an adolescent’s physical activity and SEP indicators, except for urbanization. Adolescents with higher economic status engaged in more vigorous physical activity (high: PR, 1.26; 95% confidence interval [CI], 1.25 to 1.28; middle: PR, 1.03; 95% CI, 1.02 to 1.04). Similar associations were observed for father’s education (tertiary or above: PR, 1.11; 95% CI, 1.09 to 1.13; upper secondary: PR, 1.05; 95% CI, 1.03 to 1.07) and mother’s education (tertiary or above: PR, 1.17; 95% CI, 1.15 to 1.20; upper secondary: PR, 1.06; 95% CI, 1.04 to 1.08). Adolescents with higher economic status also showed a higher compliance rate with the guideline restricting sedentary time to 2 hours per day (high: PR, 1.28; 95% CI, 1.25 to 1.30; middle: PR, 1.03; 95% CI, 1.01 to 1.05). CONCLUSIONS: Adolescents with higher SEP exhibited more physical activity and less sedentary time than those with lower SEP.

Mahitab Hanbazaza,Huda Wazzan 대한지역사회영양학회 2021 Nutrition Research and Practice Vol.15 No.S

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.

권익진,정우영 중앙대학교 다빈치미래교양연구소 2023 교양학연구 Vol.- No.24

The purpose of this study was to examine the effects of a 12-week functional training program on the physical function of sedentary college students, with a focus on sedentary behaviors. Twenty college students primarily engaged in sedentary behaviors were randomly assigned to either a control group (CON, n=8) or an exercise group (EXE, n=12). The exercise group participated in a 90-minute functional training session once a week for 12 weeks, aimed at improving joint mobility and overall body movement. The effects were evaluated using the overhead squat test to measure body angles. A 2x2 repeated measures ANOVA and independent t-tests were conducted to assess significant interaction effects. The results of this study are as follows: 1) After 12 weeks of functional training, significant improvements were observed in the right knee angle and ankle angle (p<.05). 2) Shoulder angle also showed significant improvement after 12 weeks of functional training (p<.05). 3) The pelvic tilt, as measured by vertical contrast, showed significant improvement following 12 weeks of functional training (p<.05). In conclusion, a 12-week functional training program produced positive changes in physical function among sedentary college students, particularly in the knee, ankle, shoulder, and pelvic tilt. This program may serve as an effective intervention to prevent musculoskeletal disorders and improve overall physical function in individuals primarily engaged in sedentary behaviors.

한국청소년의 신체활동과 좌식행동 및 식이행동의 건강관련행태 실천과 상호관련성 : 2008년 청소년건강행태온라인조사 분석

조강옥(Kang-Ok Cho) 한국생활환경학회 2011 한국생활환경학회지 Vol.18 No.1

A web-based survey has been administered annually since 2005 throughout Korea to assess the prevalence of adolescent health risk behaviors among middle and high school student. The aim of this study was to analyse the patterns and the interrelationships for meeting guideline of physical activity (PA), sedentary behavior (SB), and dietary behavior (DB) based on the Korea Youth Risk Behavior Web-based survey (KYRBWS) 2008 data. A cross-sectional design was used to assess 49,110 middle-high school students. PA (moderate PA≥5 times/week, or vigorous≥3 times/week) SB (watching TV, computer, DVD, video, etc. L3 hours/day), and DB (serving of fruits≥1 time/day, or vegetables≥3 times/day) were categorized into level of meeting guidelines or not. Adolescents meeting guidelines for PA, SB, and DB were 54.7% (boys 66.9%, girls 41.1%), 84.4% (boys 87.4%, girls 83.0%), and 72.6% (boys 73.2%, girls 72.0%), respectively. In addition, there were significant differences between both genders for PA (p<0.001), SB (p<0.001) and DB (p<0.01). Only 6.9% of students met all three guidelines and 13.0% did not meet all three. Students who did not meet PA were at greater fisk of not meeting SB (boys; OR 1.04, 95% CI 0.96 to 1.12, girls; OR 1.14, 95% CI 1.07 to 1.22) and DB (boys; OR 1.74, 95% CI 1.65 to 1.85, girls; OR 1.53, 95% CI 1.44 to 1.62) compared with students who met PA. The findings of this study support not an independent behavior approach but a multiple behavior approach taking into account gender and interrelationship among the physical, sedentary and dietary behaviors.

좌식행동 가이드라인 기준 개발을 위한 기초연구

조정환(Junghwan Cho),송금주(Geumju Song) 한국체육측정평가학회 2020 한국체육측정평가학회지 Vol.22 No.4

신체활동부족은 좌식행동이 주 원인으로 오늘날 좌식행동 감시 및 측정 그리고 가이드라인 개발에 대한 요구가 증가하고 있다. 이 연구는 최근의 좌식행동 관련 선행연구를 정리하여 좌식행동 가이드라인 설정 또는 권고를 위한 기초자료로 제공하고자 하는데 목적이 있다. 최근 연구들은 가이드라인에 제시된 좌식행동 지침은 그 역학적 근거가 불충분하다는데 일치하고 있다. 총 좌식시간 뿐 아니라 좌식행동 패턴은 좌식행동과 건강위험성 연관성 평가에 중요한 요소이다. 좌식행동으로 인한 좌식시간은 주로 하루 동안 누적시간으로 측정되어 왔다. 그러나 좌식시간 총량은 같은 수준이라 할지라도 좌식행동 패턴 정보는 다를 수 있다. 좌식행동 연구에서는 좌식행동 구간(bout), 중단(break), 시간 및 순서 등에 대한 정보도 필요하다. 좌식행동의 건강 위험성에 대한 우려가 갈수록 높아지고 있는 가운데 향후 좌식행동 측정을 위한 평가적 연구에 대한 관심과 지원이 필요하다. These days, there is a growing need for measurement, surveillance, and guidelines for sedentary behavior, which is a main cause of physical inactivity pandemic. This study reviewed updated scientific research on sedentary behavior to inform sitting time guidelines. In the current review, it was found that most existing sitting time guidelines lack sufficient epidemiological evidences. Not only duration of sitting time, but also its pattern is an important health risk factor. In many studies, sedentary time was measured as simply accumulated time of a day, despite the fact that its pattern may vary. Future studies should incorporate bouts, breaks, time, and sequence of sitting time. Because of increasing concerns about health risk of sitting time, more support and attention are needed for measurement and evaluation of sedentary behaviors.
