The UP4FUN Intervention Effect on Breaking Up Sedentary Time in 10- to 12-Year-Old Belgian Children: The ENERGY-Project.
Pediatr Exerc Sci
PUBLISHED: 11-13-2014
Show Abstract
Hide Abstract
There are currently no studies available reporting intervention effects on breaking up children's sedentary time. This study examined the UP4FUN intervention effect on objectively measured number of breaks in sedentary time, number of sedentary bouts (?10 mins) and total and average amount of time spent in those sedentary bouts among 10- to 12- year-old Belgian children. The total sample included 354 children (mean age: 10.9±0.7 years; 59% girls) with valid ActiGraph accelerometer data at pre- and post-test. Only few and small intervention effects were found, namely on total time spent in sedentary bouts immediately after school hours (4-6PM; ß=-3.51mins) and on average time spent in sedentary bouts before school hours (6-8.30AM; ß=-4.83mins) and immediately after school hours in favour of children from intervention schools (ß=-2.71mins). Unexpectedly, girls from intervention schools decreased the number of breaks during school hours (8.30AM-4PM; ß=-23.45breaks) and increased the number of sedentary bouts on a weekend day (ß=+0.90bouts), whereas girls in control schools showed an increase in number of breaks and a decrease in number of bouts. In conclusion, UP4FUN did not have a consistent or substantial effect on breaking up children's sedentary time and these data suggest that more intensive and longer lasting interventions are needed.

Hide Abstract
Screen-related behaviours are highly prevalent in schoolchildren. Considering the adverse health effects and the relation of obesity and screen time in childhood, efforts to affect screen use in children are warranted. Parents have been identified as an important influence on children's screen time and therefore should be involved in prevention programmes. The aim was to examine the mediating role of family-related factors on the effects of the school-based family-focused UP4FUN intervention aimed at screen time in 10- to 12-year-old European children (n child-parent dyads = 1940).

Hide Abstract
OBJECTIVES: This study aims to describe the time devoted to sedentary and physical activities at school in five European countries and to examine differences according to country, sex, ethnicity, parental education and weight status. DESIGN: cross-European cross-sectional survey. METHODS: Primary schoolchildren (n=1025) aged 10-12 years in Belgium, Greece, Hungary, the Netherlands, and Switzerland wore accelerometers for at least six consecutive days. Only weekdays were used for this study to calculate the percentages of school-time spent in sedentary activities and moderate to vigorous intensity activity. Trained research assistants measured height and weight. Sex and date of birth were self-reported by the child and parental education and ethnicity were parent-reported. RESULTS: European schoolchildren spent on average 65% of their time at school in sedentary activities and 5% on moderate to vigorous intensity activities, with small differences between countries. Girls spent a significant larger amount of school-time in sedentary activities (67%) than boys (63%; p<0.0001), and spent less time in moderate to vigorous intensity activities (4% versus 5%; p<0.001). Overweight children spent significantly less time in moderate to vigorous intensity activities (4%) that normal weight children (45%, p<0.01). Parental education or ethnicity were not associated with time spent in sedentary or physical activities. CONCLUSIONS: European schoolchildren spend a small amount of their school-time in moderate to vigorous intensity activities and a large amount in sedentary activities, with small but significant differences across countries. Future interventions should target more physical activities and less sedentary time at school particularly in girls.

Mediating effects of home-related factors on fat intake from snacks in a school-based nutrition intervention among adolescents.
Health Educ Res
PUBLISHED: 12-08-2011
Show Abstract
Hide Abstract
The purpose of the present study was to investigate if the effects of the parental component of a school-based intervention on dietary fat intake from snacking were mediated by changes in home-related factors. A random sample of 10 schools with 2232 pupils aged 11-15 years was randomly assigned to one of two intervention groups [one with (n = 1226) and one without a parental component (n = 1006)]. Fat intake, home availability of low-fat foods and parental encouragement and support to eat a low-fat diet were assessed with validated self-administered questionnaires. Mediation was assessed with the product-of-coefficient test. Changes in home-related determinants were significantly related to changes in fat intake from snacks; therefore, school-based obesity programmes on adolescents should try to address these determinants. In the present study, one of the three investigated home-related factors, namely parental support, was affected by the parental component intervention. Decreases in parental support were prevented. These changes in parental support were found to mediate the parental intervention effects on changes in fat intake from snacks. Home-related factors appear to be related to changes in adolescents snacking behaviours, therefore, school-based obesity programmes should target them. Nevertheless, more research is needed concerning effectively addressing the other determinants.

Hide Abstract
Overweight and obesity in youth has increased dramatically. Therefore, overweight prevention initiatives should start early in life and target modifiable energy balance-related behaviours. Parental participation is often advocated as important for school-based interventions, however, getting parents involved in school-based interventions appears to be challenging based on earlier intervention experiences. The purpose of this study was to get insight into the determinants of and perspectives on parental participation in school-interventions on energy balance-related behaviours (physical activity, healthy eating, sedentary behaviours) in parents of ten- to twelve-year olds in order to develop an effective parental module for school-based interventions concerning energy balance-related behaviours.

Within the Self-Determination Theory (SDT) framework, the first major study aim was to investigate the SDT tenets in an obese adolescent population by examining the factor structure of the Behavioural Regulation in Exercise Questionnaire-2 (BREQ-2) and by investigating associations between physical activity (PA) and motivation in obese adolescents. The second aim was to study differences in motivation according to adolescents educational level, since lower educated obese adolescent are a sub-risk group for lower PA levels among the obese adolescents. The third aim was to investigate whether attending a residential obesity treatment program could lead to an increase in autonomous motivation towards PA and to see if the treatment effect on motivation was different in low versus high educated youth.

Objectively measured sedentary time and physical activity time across the lifespan: a cross-sectional study in four age groups.
Int J Behav Nutr Phys Act
Show Abstract
Hide Abstract
From a health perspective it is suggested to promote a positive balance between time spent in light intensity physical activity (LIPA) and sedentary behaviour (SB) (i.e. spending more time in LIPA than time spent in SB). However, no studies have reported prevalence rates of the LIPA-SB balance yet. The aim of this study was to objectively investigate the time spent in SB, in LIPA and moderate-to-vigorous intensity physical activity (MVPA) in four Belgian age groups and to explore which proportion of the population had a favorable balance between LIPA and SB and combined this with recommended amount of MVPA.

Hide Abstract
The aim of this study is to investigate associations of family-related factors with childrens fruit drink/juice and soft drink consumption. A cross-sectional survey among 10- to 12-year-old children and their parents in eight European countries was conducted to gather this data. Key variables of interest were childrens self-reported fruit drink/juice and soft drink intake per day (outcome) and family-related factors (based on parents report) related to these two behaviors (modeling, automaticity, availability, monitoring, permissiveness, negotiating, communicating health beliefs, avoid negative modeling, self-efficacy, rewarding, and family consumption). 7915 Children (52% girls; mean age=11.7 ± 0.8 years) and 6512 parents (83% women; mean age=41.4 ± 5.3 years) completed the questionnaire. Multilevel regression analyses were used to examine the aforementioned associations. Three of the 11 family-related factors (modeling, availability, and family consumption) were positively associated with childrens fruit drink/juice and soft drink intake. Additionally, three family-related factors (permissiveness, monitoring, and self-efficacy) were solely associated with soft drink intake and one family-related factor (communicating health beliefs) was related to fruit drink/juice intake. Future interventions targeting childrens fruit drink/juice and soft drink intake should focus on the home environment, parents and their practices, especially on parents fruit drink/juice and soft drink intake and availability of these beverages at home.

Self-reported TV and computer time do not represent accelerometer-derived total sedentary time in 10 to 12-year-olds.
Eur J Public Health
Show Abstract
Hide Abstract
Screen-time activities are often used as proxies for sedentary time. We studied associations of self-reported television (TV), computer and total screen-time with accelerometer-derived total sedentary time in European children (10-12 years). Analyses showed significant positive associations between TV, computer and total screen-time with total sedentary time for the total sample, however, the explained variance was low and stratified analyses only revealed a significant positive association between total screen-time and total sedentary time in boys and between computer time and total sedentary time in Dutch children. This suggests that self-reported TV and computer time do not adequately reflect total sedentary time in schoolchildren.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
