Sedentary time in a nationally representative sample of adults in Japan: Prevalence and sociodemographic correlates.

Sedentary behaviour is associated with risks of detrimental health outcomes. It is crucial to understand how much time people spend in sedentary behaviour and what factors affect too much sedentary time for effective intervention. However, few studies examined the prevalence and the correlates of sedentary behaviour in Japan. Therefore, we assessed total sedentary time and its sociodemographic correlates using a nationally representative sample of adults in Japan. Cross-sectional data from Sports-Life Survey in 2016 and 2018 conducted by Sasagawa Sports Foundation was used. Participants' sociodemographic factors and total sedentary time were collected by questionnaires. We classified those with<8h/day of total sedentary time as "low-sedentary" and those with≥8h/day of total sedentary time as "high-sedentary". A multiple logistic regression model was applied to calculate adjusted odds ratios and 95% confidence intervals (95% CIs) for the association of each variable with the "high-sedentary" group (≥8h/day). In total, 5,346 participants were included in the analyses. On average, time spent in sedentary behaviour was 5.3h/day (SD=3.7) among Japanese adults. The percentage of "high-sedentary" was 25.3% (95% CI: 24.1-26.4) and higher body mass index (≥25 kg/m2), being unmarried, unemployment, and higher educational level (graduate school or university) were positively associated with being "high-sedentary". In conclusion, higher sedentary time was among people with higher body mass index, being unmarried, unemployed, and higher education. Intervention for reducing sedentary time should be developed, targeting people with these characteristics.

Sedentary behavior patterns over 6 weeks among ambulatory people with stroke

ABSTRACT Objective: To describe patterns of sedentary behavior over 6 weeks among ambulatory people with subacute and chronic stroke. Design: Observational longitudinal study with assessments at baseline (T0) and week 6 (T1). Methods: Community-dwelling people with stroke (n = 39) pooled from two studies who were ≥18 years of age were assessed for sedentary behavior at 2 timepoints (T0, T1). Sedentary behavior was measured with the activPAL micro3 following a 7-day wear protocol to obtain mean daily: total sitting time, sitting time accumulated in bouts ≥30 minutes, number of sit-to-stand transitions, and fragmentation index (sit-to-stand transitions/total sitting hours). Paired samples t-tests were used to calculate mean group differences in sedentary behavior metrics between T0 and T1 (α =.05). Cohen’s d was calculated to describe the magnitude of within-person change between T0 and T1. Results: There were no statistically significant within-person differences between T0 and T1 on mean daily sitting time (Cohen’s d= −0.21, p=.19), sitting time accumulated in bouts ≥30 minutes (d= −0.27, p=.11), number of sit-to-stand transitions (d= −0.02, p=.53), or the fragmentation index (d= −0.11, p=.92). Conclusions: Sedentary behavior metrics were stable for over 6 weeks. The number of sit-to-stand transitions per day and the fragmentation index appeared to be the most stable indicators over 6 weeks. Future research should confirm these findings and identify correlates of sedentary behavior among people with stroke.

The Built Environment and Socio-Demographic Correlates of Partial and Absolute Sedentary Behaviours in Community-Dwelling Older Adults in Accra, Ghana.

This study examined built environmental and socio-demographic variables as correlates of sedentary behaviour in a population of older adults, and attempted to introduce the idea of measuring sedentary behaviour with two domains, namely 'partial sedentary behaviour' and 'absolute sedentary behaviour'. The study's population was community-dwelling older adults aged 60years or more in Accra, Ghana. A self-reported questionnaire was used to gather data from 504 older people. Multiple linear regression analysis was used to present findings, with all nominal categorical variables incorporated in this analysis dummy-coded. The overall (third) regression model accounted for a variance of 55.9% and a significant F-test [F (25,454) = 22.99; p < 0.001)]. Gender was positively associated with sedentary behaviour - the sedentary behaviour of women was 28min in excess of that of men. Sedentary behaviour decreased as the social network size and supporting social network of older people increased. Sedentary behaviour decreased as availability of spacious road pavements, secure social recreational centres for older people, and health services in the community increased. The improvement of road safety conditions at the community level and design of the built environment to support social integration of older people are major recommendations of this study.

Correlates of sedentary behaviour in Asian adults: A systematic review

The objective of this study is to systematically review the evidence on correlates of sedentary behaviour (SB) among Asian adults. We searched for studies that examined individual, environmental, and political/cultural correlates of total and domain-specific SB (transport, occupation, leisure, and screen time) in Asian adults published from 2000 onwards in nine scientific databases. Two reviewers independently screened identified references. Following quality assessment of included studies, we performed narrative synthesis that considered differences based on SB measurements, regions, and population characteristics (PROSPERO: CRD42018095268). We identified 13 249 papers of which we included 49, from four regions and 12 countries. Researchers conducted cross-sectional analyses and most relied on SB self-report for SB measurement. Of the 118 correlates studied, the following associations were consistent: higher age, living in an urban area (East Asia), and lower mental health with higher total SB; higher education with higher total and occupational SB; higher income with higher leisure-time SB; higher transit density with higher total SB in older East Asians; and being an unmarried women with higher SB in the Middle East. We encourage more research in non-high-income countries across regions, further exploration of important but neglected correlates using longitudinal designs and qualitative research, and the use of objective instruments to collect SB data.

Correlates of sedentary behaviour among adolescents and adults with hazardous, harmful or dependent drinking in South Africa.

BackgroundThere is lack of information on the correlates of sedentary behaviour among persons with alcohol use disorders. The study aimed to examine socio-demographic and health correlates among adolescents and adults with hazardous, harmful or probable dependent alcohol use (= problem drinking).MethodData from the cross-sectional South African National Health and Nutrition Examination Survey (SANHANES-1) 2011–12 were analysed. From a total sample of 15 085 persons aged 15 years and older, 2849 adolescents and adults (mean age = 37.1 years, standard deviation [s.d.] = 15.1) were identified as problem drinkers, based on the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C). Multivariable logistic and linear regression were used to determine the associations between socio-demographic characteristics, health variables and high sedentary behaviour (≥8 h/day) and total minutes of sedentary behaviour a day.ResultsThe prevalence of high sedentary behaviour (≥ 8 h/day) was 11.9% overall (11.9% among men and 12.1% among women), and the mean (s.d.) duration of sedentary behaviour was 263 (169) min/day. In bivariate analysis, older age, population group, functional disability, cognitive impairment, having hypertension, having had a stroke and posttraumatic symptoms were correlated with high sedentary behaviour. In adjusted logistic regression analysis, older age and being Indian or Asian were positively, and having been diagnosed with angina was negatively, associated with high sedentary behaviour. In linear regression analysis, older age, not employed and having had a stroke were positively, and being of mixed race and having angina were negatively, associated with total minutes (up to 960 min/day) of sedentary behaviour in a day.ConclusionThe study provides socio-demographic and health correlates of sedentary behaviour among problem drinkers. This information can guide possible future interventions in reducing sedentary behaviour among problem drinkers.

Correlates of sedentary behavior among university students with depression from 22 low- and middle-income countries

ABSTRACTThe present study utilized a large, multi-country sample and aimed to examine the correlates of sedentary behavior in university students with depression in 22 low- and middle-income countries. In a cross-sectional survey, university students (median age 20 years, interquartile range = 3) from 22 countries in the Americas, Africa, and Asia responded to self-reported measures of sedentary behavior and health indicators. Overall, among 1693 university students with depression, 36.3% engaged in 8 or more hours a day sedentary time. In the final logistic regression model, residing in a low-income or lower middle-income country and inadequate fruit and vegetable consumption were positively and having sustained an injury in the past year was negatively associated with high sedentary behavior. Findings suggest that sedentary behavior interventions in university students with depression could target at-risk groups identified in this study.

Social-cognitive theory variables as correlates of sedentary behavior in multiple sclerosis: Preliminary evidence

BackgroundPersons with multiple sclerosis(MS) engage in substantially more sedentary behavior than adults from the general population. ObjectiveHypothesis: This preliminary, cross-sectional study examined social-cognitive theory(SCT) variables as correlates of sedentary behavior in MS. We hypothesized that scores from SCT variables for sedentary behavior change would correlate with scores from self-reported and device-measured volumes of sedentary behavior in MS. We further hypothesized that the correlations would be stronger for self-reported than device-measured sedentary behavior, and that the primary correlate of sedentary behavior would be self-efficacy. MethodsWe recruited participants through a random sample of 1,000 persons enrolled in the North American Research Committee on MS registry, and 275 of the 296 persons who underwent screening volunteered for the study. Participants wore an ActiGraph accelerometer on a belt around the waist for measuring minutes per day of sedentary behavior. Participants further completed a newly-created, study-specific measure of SCT variables for reducing sedentary behavior(i.e., self-efficacy, outcome expectations, barriers, goal setting, & planning) and the abbreviated International Physical Activity Questionnaire as a self-report measure of sitting time. ResultsSelf-reported sedentary behavior was associated with self-efficacy(r = −0.47), goal setting(r = −0.31), planning(r = −0.35), and barriers(r = 0.39) for reducing sedentary behavior. Device-measured sedentary behavior was associated with self-efficacy(r = −0.32), goal setting(r = −0.21), planning(r = −0.18), and barriers(r = 0.20). Self-efficacy(β = −0.29), barriers(β = 0.26), and planning(β = −0.24) independently explained variance in self-reported sedentary behavior(R2 = 0.33). Only self-efficacy(β = −0.32) independently explained variance in device-measured sedentary behavior(R2 = 0.10). ConclusionSCT constructs might be reasonable targets of a behavioral intervention for reducing sedentary behavior in MS.

Correlates of Sedentary Behaviour in Adults with Intellectual Disabilities-A Systematic Review.

Individuals with intellectual disabilities (ID) are at high risk for high levels of sedentary behaviour. To inform the development of programmes to reduce sedentary behaviour, insight into the correlates is needed. Therefore, the aim of this study is to review the evidence on correlates of sedentary behaviour in adults with ID. We performed a systematic literature search in Ovid Medline, Ovid Embase, Web of Science and Google Scholar up to 19 January 2018, resulting in nine included studies that were published from 2011 to 2018. Correlates were categorized according to the ecological model. Studies predominantly focused on individual level correlates. Of those correlates studied in more than one study, having epilepsy was associated with less sedentary behaviour and inconsistent results were found for sex, genetic syndromes, weight status, physical health, mobility, level of ID, and mental health. Of the few interpersonal and environmental factors studied, only living arrangements were studied in more than one study, with inconsistent results. To date, we have limited and inconclusive evidence about correlates of sedentary behaviour in adults with ID. Only when future studies unravel correlates and determinants, across all domains of the ecological model, will the potential opportunities to improve health by reducing sedentary behaviour come within reach.

Social correlates of leisure-time sedentary behaviours in Canadian adults.

Research on the correlates of sedentary behaviour among adults is needed to design health interventions to modify this behaviour. This study explored the associations of social correlates with leisure-time sedentary behaviour of Canadian adults, and whether these associations differ between different types of sedentary behaviour. A sample of 12,021 Canadian adults was drawn from the 2012 Canadian Community Health Survey, and analyzed using binary logistic regression to model the relationships that marital status, the presence of children in the household, and social support have with overall time spent sitting, using a computer, playing video games, watching television, and reading during leisure time. Covariates included gender, age, education, income, employment status, perceived health, physical activity level, body mass index (BMI), and province or territory of residence. Extensive computer time was primarily negatively related to being in a common law relationship, and primarily positively related to being single/never married. Being single/never married was positively associated with extensive sitting time in men only. Having children under 12 in the household was protective against extensive video game and reading times. Increasing social support was negatively associated with extensive computer time in men and women, while among men increasing social support was positively associated with extensive sitting time. Computer, video game, television, and reading time have unique correlates among Canadian adults. Marital status, the presence of children in the household, and social support should be considered in future analyses of sedentary activities in adults.

A review of occupational physical activity and sedentary behaviour correlates.

Physical activity reduces the risk of morbidity and high sedentary time may be associated with negative health outcomes. The workplace offers an arena to promote physical activity and reduce sedentary time, but existing workplace-based interventions have typically yielded small effects. To collate the literature on correlates of occupational physical activity and sedentary behaviour and to inform future novel approaches to workplace-based intervention or policy. Systematic literature searches were conducted in December 2014 using multiple databases. Identified papers were screened against an inclusion criterion. Papers were deemed eligible for this review if they included occupational physical activity and sedentary behaviour as an outcome, were quantitative observational studies and included an adult working population. Identified correlates of occupational physical activity and sedentary behaviour were organized into levels of the socioecological model. Forty studies met the inclusion criterion. A higher number of studies included only occupational physical activity, not sedentary time, as an outcome and were carried out in the USA and Australia. The review identified that white-collar workers are at greater risk of low occupational physical activity and high sedentary time. The majority of correlates found to be associated with occupational physical activity and sedentary time were intrapersonal and non-modifiable. Intervention efforts to increase occupational physical activity and reduce sedentary time may be most effective when targeted at white-collar workers. Research is needed to identify additional modifiable correlates of occupational physical activity and sedentary behaviour, in white-collar workers.

Caregiving, Transport-Related, and Demographic Correlates of Sedentary Behavior in Older Adults: The Senior Neighborhood Quality of Life Study.

Excess sedentary time predicts negative health outcomes independent of physical activity. The present investigation examined informal caregiving duties and transportation-related factors as potential correlates of sedentary behavior in older adults. Average daily sedentary time was measured via accelerometer in adults ages 66 years and older (N = 861). Caregiving variables included dog ownership and informal family caregiving status. Transportation variables included driver status, walking distance to public transit, and reported presence of pedestrians and bicyclists in one's neighborhood. In multivariate models, owning a dog and being a driver were associated with less sedentary time (p ≤ .01). Educational status and geographic region modified the association between dog ownership and sedentary time, and age modified the association between driver status and sedentary time. This study identified that older adult dog owners and drivers were less sedentary. Both factors may create opportunities for older adults to get out of their homes.

Sedentary behaviour and physical activity in bronchiectasis: a cross-sectional study.

BackgroundThe impact of bronchiectasis on sedentary behaviour and physical activity is unknown. It is important to explore this to identify the need for physical activity interventions and how to tailor interventions to this patient population. We aimed to explore the patterns and correlates of sedentary behaviour and physical activity in bronchiectasis.MethodsPhysical activity was assessed in 63 patients with bronchiectasis using an ActiGraph GT3X+ accelerometer over seven days. Patients completed: questionnaires on health-related quality-of-life and attitudes to physical activity (questions based on an adaption of the transtheoretical model (TTM) of behaviour change); spirometry; and the modified shuttle test (MST). Multiple linear regression analysis using forward selection based on likelihood ratio statistics explored the correlates of sedentary behaviour and physical activity dimensions. Between-group analysis using independent sample t-tests were used to explore differences for selected variables.ResultsFifty-five patients had complete datasets. Average daily time, mean(standard deviation) spent in sedentary behaviour was 634(77)mins, light-lifestyle physical activity was 207(63)mins and moderate-vigorous physical activity (MVPA) was 25(20)mins. Only 11% of patients met recommended guidelines. Forced expiratory volume in one-second percentage predicted (FEV1% predicted) and disease severity were not correlates of sedentary behaviour or physical activity. For sedentary behaviour, decisional balance ‘pros’ score was the only correlate. Performance on the MST was the strongest correlate of physical activity. In addition to the MST, there were other important correlate variables for MVPA accumulated in ≥10-minute bouts (QOL-B Social Functioning) and for activity energy expenditure (Body Mass Index and QOL-B Respiratory Symptoms).ConclusionsPatients with bronchiectasis demonstrated a largely inactive lifestyle and few met the recommended physical activity guidelines. Exercise capacity was the strongest correlate of physical activity, and dimensions of the QOL-B were also important. FEV1% predicted and disease severity were not correlates of sedentary behaviour or physical activity. The inclusion of a range of physical activity dimensions could facilitate in-depth exploration of patterns of physical activity. This study demonstrates the need for interventions targeted at reducing sedentary behaviour and increasing physical activity, and provides information to tailor interventions to the bronchiectasis population.Trial registrationNCT01569009 (“Physical Activity in Bronchiectasis”)Electronic supplementary materialThe online version of this article (doi:10.1186/s12890-015-0046-7) contains supplementary material, which is available to authorized users.

Individual, Social, and Neighborhood Associations With Sitting Time Among Veterans.

Sedentary behavior is an increasingly recognized health risk factor, independent of physical activity. Although several correlates of sedentary behavior are known, little research has identified them among U.S. veterans, a population that faces disproportionate chronic disease burden. A survey was mailed to 1997 randomly selected veterans at a large urban Veterans Affairs medical center in 2012 and remailed in 2013 to nonresponders, resulting in a 40% response rate. We examined individual-, social-, and neighborhood-level factors in association with self-reported sitting time. Factors correlated with sitting time at P < .05 were included in a multiple linear regression model. In the multivariate model, higher depression (B = 7.8), body mass index (B = 5.1), functional impairment (B = 4.2), and self-rated health (B = 68.5) were significantly associated with higher sitting time, and leisure time physical activity (B = -0.10) and being employed (B = -71.3) were significantly associated with lower sitting time. Individual-level, but not social- and neighborhood-level, variables were associated with sitting time in this population. This study identified individual-level targets for reducing sitting time and improving overall health among veterans.

Correlates of urban children's leisure‐time physical activity and sedentary behaviors during school days

Understanding correlates of physical activity and sedentary behaviors may contribute to fostering active lifestyles. This study aimed to identify correlates of physical activity and sedentary behaviors in leisure-time among Portuguese urban children, during school days. A cross-sectional survey was conducted with 802 students (416 boys), aged 10-12 years. A questionnaire was used to collect data of physical activity, sedentary behaviors, psychological and behavioral variables related to physical activity and sedentary behaviors. Analyses were run separately for boys and girls. Television viewing occupied the most leisure-time of boys and girls, followed by computer usage, and video game playing. These behaviors occupied 259.7 min/day for boys and 208.6 for girls (P = 0.002). Reported moderate-to-vigorous physical activity was 23.7 min for boys and 12.8 min for girls (P < 0.001). Perception of competence and academic achievement were related to physical activity for the boys and girls. Computer use and playing video games with friends were only related to physical activity for the boys. On the other hand, parents' physical activity participation was related with boys' and girls' physical activity. The correlates of sedentary behavior were outdoor play for the boys, age for the girls, and playing video games with friends for both. This finding suggests that interventions should be considered to replace joint video game time with joint physical activity time.

Correlates of sedentary behaviours in preschool children: a review.

BackgroundSedentary behaviour has been linked with a number of health outcomes. Preschool-aged children spend significant proportions of their day engaged in sedentary behaviours. Research into the correlates of sedentary behaviours in the preschool population is an emerging field, with most research being published since 2002. Reviews on correlates of sedentary behaviours which include preschool children have previously been published; however, none have reported results specific to the preschool population. This paper reviews articles reporting on correlates of sedentary behaviour in preschool children published between 1993 and 2009.MethodsA literature search was undertaken to identify articles which examined correlates of sedentary behaviours in preschool children. Articles were retrieved and evaluated in 2008 and 2009.ResultsTwenty-nine studies were identified which met the inclusion criteria. From those studies, 63 potential correlates were identified. Television viewing was the most commonly examined sedentary behaviour. Findings from the review suggest that child's sex was not associated with television viewing and had an indeterminate association with sedentary behaviour as measured by accelerometry. Age, body mass index, parental education and race had an indeterminate association with television viewing, and outdoor playtime had no association with television viewing. The remaining 57 potential correlates had been investigated too infrequently to be able to draw robust conclusions about associations.ConclusionsThe correlates of preschool children's sedentary behaviours are multi-dimensional and not well established. Further research is required to provide a more comprehensive understanding of the influences on preschool children's sedentary behaviours to better inform the development of interventions.
