Agreement between parent and child report on parental practices regarding dietary, physical activity and sedentary behaviours: the ENERGY cross-sectional survey.
BMC Public Health
PUBLISHED: 09-05-2014
Show Abstract
Hide Abstract
Parents and their parenting practices play an important role in shaping their children's environment and energy-balance related behaviours (EBRBs). Measurement of parenting practices can be parent- or child-informed, however not much is known about agreement between parent and child perspectives. This study aimed to assess agreement between parent and child reports on parental practices regarding EBRBs across different countries in Europe and to identify correlates of agreement.

Hide Abstract
BACKGROUND: The aim of the study was to examine the association of daily variations in rainfall and temperature with sedentary time (ST) and physical activity (PA) in European children. METHODS: Children were included from five countries (Belgium, Greece, Hungary, the Netherlands, Switzerland) as part of the ENERGY- project. We used cross-sectional data from 722 children aged 10-12 years (47% boys). ST and PA were measured by accelerometers for six consecutive days, including weekend days. Weather data was collected from online national weather reports. Multilevel regression models were used for data analyses. RESULTS: Maximum temperature was positively associated with light PA (b=3.1 min/day; 95% CI=2.4; 3.8), moderate-to-vigorous PA (b=0.6 min/day; 95% CI=0.4; 0.8) and average PA (b=4.1 counts per minute (cpm); 95% CI=1.6; 6.5, quadratic relationship). Rainfall was inversely and quadratically associated with light PA (b=-1.3 min/day; 95% CI=-1.9; -0.6), moderate-to-vigorous PA (b=-0.6 min/day; 95% CI=-0.8; -0.3) and average PA (b=-1.6 cpm; 95% CI=-2.2; -0.9). Maximum temperature was not significantly associated with ST (b=-0.2 min/day; 95% CI=-1.0; 0.6), while rainfall was positively associated with ST (b=0.9 min/day; 95% CI=0.6, 1.3). CONCLUSION: The present study shows that temperature and rainfall are significantly associated with PA and ST in 10-12 years European children.

Study protocol of physical activity and sedentary behaviour measurement among schoolchildren by accelerometry--cross-sectional survey as part of the ENERGY-project.
BMC Public Health
PUBLISHED: 02-11-2011
Show Abstract
Hide Abstract
Physical activity and sedentary behaviour among children should be measured accurately in order to investigate their relationship with health. Accelerometry provides objective and accurate measurement of body movement, which can be converted to meaningful behavioural outcomes. The aim of this study was to evaluate the best evidence for the decisions on data collection and data processing with accelerometers among children resulting in a standardized protocol for use in the participating countries.

Assessment of intensity, prevalence and duration of everyday activities in Swiss school children: a cross-sectional analysis of accelerometer and diary data.
Int J Behav Nutr Phys Act
PUBLISHED: 01-06-2009
Show Abstract
Hide Abstract
Appropriately measuring habitual physical activity (PA) in children is a major challenge. Questionnaires and accelerometers are the most widely used instruments but both have well-known limitations. The aims of this study were to determine activity type/mode and to quantify intensity and duration of childrens everyday PA by combining information of a time activity diary with accelerometer measurements and to assess differences by gender and age.

Differences in weight status and energy-balance related behaviors among schoolchildren in German-speaking Switzerland compared to seven countries in Europe.
Int J Behav Nutr Phys Act
Show Abstract
Hide Abstract
Overweight in children and adolescents have increased significantly and are a major public health problem. To allow international comparisons, Switzerland joined the European study ENERGY cross sectional survey consortium that investigated the prevalence of overweight and obesity as well as selected dietary, physical and sedentary behaviors of 10-12 years old pupils across seven other countries in Europe. The aims of the present study was to compare body composition and energy-balance related behaviors of Swiss schoolchildren to those of the seven European ENERGY-countries and to analyze overweight and energy-balance related behaviors of Swiss children according to socio-demographic factors.

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.

Measuring and validating physical activity and sedentary behavior comparing a parental questionnaire to accelerometer data and diaries.
Pediatr Exerc Sci
Show Abstract
Hide Abstract
Accurately measuring childrens physical activity and their sedentary behavior is challenging. The present study compared 189 parental responses to a questionnaire surveying physical activity and sedentary behavior of children aged 6-14 years, to accelerometer outputs and time activity diaries for the same group. Responses were analyzed taking age, sex and maternal education into account. Correlation coefficients between questionnaire reports and accelerometer-based physical activity across all age groups were acceptable (up to r = .55). Yet, adjustment for age markedly attenuated these associations, suggesting concomitant influences of biological and behavioral processes linked to age. The comparisons of general time indications in the questionnaire with 24h-diary records suggested that parents tended to under- and over-report single activities, possibly due to social desirability. We conclude that physical activity questionnaires need to be designed for specific age groups and be administered in combination with objective measurements.

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.

Reactivity to Accelerometer Measurement of Children and Adolescents.
Med Sci Sports Exerc
Show Abstract
Hide Abstract
Awareness of being monitored can influence participants habitual physical activity (PA) behavior. This reactivity effect may threaten the validity of PA assessment. Reports on reactivity when measuring the PA of children and adolescents have been inconsistent. The aim of this study was to investigate whether PA outcomes measured by accelerometer devices differ from measurement day to measurement day, and whether the day of the week and the day on which measurement started influence these differences.

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.
