Correlates of Total Sedentary Time and Screen Time in 9-11 Year-Old XXXX around the World: The International Study of Childhood Obesity, Lifestyle and the Environment.

@entity1 @entity1054 @entity146
PURPOSE: Previously, studies examining correlates of @entity146 have been limited by small sample size, restricted geographic area, and little socio-cultural variability. Further, few studies have examined correlates of total @entity1054 ( @entity1054 ) and screen time (ST) in the same population. This study aimed to investigate correlates of @entity1054 and ST in @entity1 around the world. METHODS: The sample included 5,844 @entity1 (45.6% @entity1 , mean age = 10.4 years) from study sites in Australia, Brazil, Canada, China, Colombia, Finland, India, Kenya, Portugal, South Africa, the United Kingdom, and the United States. @entity1 - and parent-reported behavioral, household, and neighborhood characteristics and directly measured anthropometric and accelerometer data were obtained. Twenty-one potential correlates of @entity1054 and ST were examined using multilevel models, adjusting for sex, age, and highest parental education, with school and study site as random effects. Variables that were moderately associated with @entity1054 and/or ST in univariate analyses (p<0.10) were included in the final models. Variables that remained significant in the final models (p<0.05) were considered correlates of @entity1054 and/or ST. RESULTS: @entity1 averaged 8.6 hours of daily @entity1054 , and 54.2% of @entity1 failed to meet ST guidelines. In all study sites, @entity1 reported higher ST, were less likely to meet ST guidelines, and had higher BMI z-scores than @entity1 . In 9 of 12 sites, @entity1 engaged in significantly more @entity1054 than @entity1 . Common correlates of higher @entity1054 and ST included poor weight status, not meeting physical activity guidelines, and having a TV or a computer in the bedroom. CONCLUSIONS: In this global sample many common correlates of @entity1054 and ST were identified, some of which are easily modifiable (e.g., removing TV from the bedroom), and others that may require more intense behavioral interventions (e.g., increasing physical activity). Future work should incorporate these findings into the development of culturally meaningful public health messages.
