The objective was to study associations between socioeconomic status (SES), weight status, and sex, with children's participation in sedentary behaviours and sport.
Children (aged 9-10 years; n = 6,337) completed a questionnaire to establish how long they spent in sedentary behaviours and sport participation during week days and weekend days. Height and weight were measured to calculate body mass index. Associations between dependent and independent variables were investigated using hierarchical loglinear analysis.
A significantly greater proportion of boys than girls spent > or = 1 h per weekday and weekend day watching television (TV) (p < 0.001), playing video games (p < 0.001), and participating in sport (p < 0.001). TV viewing and video gaming for > or = 1 h per day were inversely associated with SES (p = 0.001), whilst the greatest proportion of children participating in sport for > or = 1 h were in the highest SES quartile (p < 0.001). Overweight girls were more likely than normal weight girls to use the internet for > or = 1 h per weekend day (p < 0.001).
Relatively more lower SES children spent time in sedentary behaviours than sport participation. Weight status was not consistently associated with sedentary behaviours. Proportionately more boys than girls watched TV, played video games, and participated in sport, suggesting that boys find time for sedentary behaviours and physical activity. Efforts should be made to address inequalities in the prevalence of sedentary behaviours and sport participation for all children regardless of SES, weight status, or sex.

    • "As a result of this transformation, the 'benefit judgment' variable had two categories ('synergistic' and 'non-synergistic') and the data met the test assumptions for three-way analysis. The practice of collapsing categories in this manner is commonly employed hierarchical loglinear analysis (e.g., Dawson et al., 2014, Fairclough, Boddy, Hackett, and Stratton, 2009). To further facilitate the tests, the health interest (HI), education level (EL) and numeracy variables were converted to dichotomous categorical variables as described below. "

    ABSTRACT: Objective: Numerous scientific studies show that certain combinations of dietary and/or lifestyle factors produce health benefits which are greater than the sum of the benefits associated with each factor alone. To address an existing knowledge gap, we assessed the extent to which individuals understand that certain combinations present these 'synergistic health benefits'. Design: Health benefit judgments were obtained from lay adults for a range of dietary and/or lifestyle combinations that have been found to present synergistic benefits. Association between these judgments and socio-cognitive characteristics such as numeracy, education, and health interest (HI) were examined. Methods: Three hundred and fifty-two Swiss adults were presented with a description of one of eight synergistically beneficial combinations. Each participant provided a categorical benefit judgment (i.e., subadditive, additive, or synergistic) for the combination and explained the cognitive reasoning underlying their judgment. Participants completed measures of numeracy and HI. Results: The proportion of combinations judged to present a synergistic benefit was modest for 'macro-level' combinations (e.g., diet and exercise), but low for 'micro-level' combinations (e.g., two phytochemicals). Cognitive reasoning data showed that a higher proportion of judgments for micro-level (cf. macro-level) combinations were based on greater subjective epistemic uncertainty. Higher interest in health was associated with a better understanding of synergistic benefits, but numeracy and education level were not. Conclusions: There is considerable scope to improve the extent to which lay adults understand that specific combination of diet and lifestyle behaviours can synergistically benefit their health. Our results enable us to make informed recommendations for public health interventions.

    • "Sex differences may partially be explained by the higher energy expenditure resulted from the higher frequency of physical activity in boys, as they practice more physical activity than girls. This result is similar to those from another study that found that boys spend more time in both sedentary behaviour and physical activities than girls (Fairclough et al., 2009). "

    ABSTRACT: Objective: To determine whether high blood pressure is associated with sedentary behavior in young people even after controlling for potential confounders (sex, age, socioeconomic level, tobacco, alcohol, obesity and physical activity). Methods: Epidemiological study in which 1231 adolescents were evaluated. Blood pressure was measured by an oscillometric device and waist circumference measured with an inextensible tape. Sedentary behavior (television + computer + game) and physical activity were assessed by a questionnaire. We used mean and standard deviation to describe the statistical analysis, and the association between high blood pressure and sedentary behavior was assessed by the chi-square test. Binary Logistic Regression was used to observe the magnitude of association and cluster analyses (sedentary behavior + abdominal obesity; sedentary behavior + physical inactivity). Results: High blood pressure was associated with sedentary behaviors (OR=2.21 [CI=1.41-3.96]), even after controlling for various confounders (OR=1.68 [CI= 1.03-2.75]). In cluster analysis the combination of sedentary behavior and elevated abdominal obesity contributes significantly to the increased likelihood of having high blood pressure (OR= 13.51 [CI 7.21-23.97]). Conclusions: Sedentary behavior was associated with high blood pressure, and excess fat in the abdominal region contributed to the modulation of this association.

    • "Understanding how home environments, where children spend significant time, influence children's activity behaviors could lead to evidence-based interventions (Birch and Davison, 2001; Maitland et al., 2013). Children's activity encompasses both physical activity and sedentary behavior, each of which has different associated influences and health implications (Davison and Lawson, 2006; Fairclough et al., 2009; Gebremariam et al., 2013; Marshall and Ramirez, 2011).

    ABSTRACT: Background: Given the obesity epidemic, it is critical to understand factors associated with youth physical activity and sedentary behavior at home, where youth spend significant time. We examined relationships between these child behaviors and home environment factors. Methods: Data were obtained from 713 children aged 6 to 11 in Washington and California 2007-2009. Multivariate regression analyses controlling for socio-demographics examined associations between parent-reported home environment factors and child's accelerometer-measured moderate-to-vigorous physical activity (MVPA) and sedentary time, overall and at home, and parent-reported child screen time. Results: Children averaged 47.2% of time at home, which included 43.6% and 46.4% of overall MVPA and sedentary behavior, respectively. Parental support for physical activity and having a basketball hoop were positively associated with MVPA and negatively associated with sedentary behavior. Combined parental support and a basketball hoop was associated with even higher MVPA. Children with fewer bedroom media devices and more fixed play equipment had lower overall sedentary behavior and screen time than either factor alone. Findings were similar regardless of weight status. Conclusions: Physical and social home environment variables, especially when combined, were related to more child MVPA and less sedentary behavior. Results support addressing multiple home environment factors in childhood obesity prevention.
