Probability of meeting the restrained sitting guideline in early childhood: an international cross sectional study

Objectives: To estimate the proportion of children who meet the restrained sitting guidelines (i.e.<1 hour in continuous restrained sedentary).The secondary aim was to determine which factors contribute to the probability a child will meet the restrained sitting guidelines.Design:Secondary data analysis of 32 countries participating in the SUNRISE International Study.Methods: Parent surveys were used to collect child demographic information and total restrained sitting.Physical activity was assessed with an accelerometer (ActiGraph wGT3X-BT).A generalized linear mixed model was used to determine the probability of a child meeting the restrained sitting guidelines based on sex, age, geographic region, time spent in a vehicle, and hours of total physical activity.Separate models were run by country income level.Results:Final analysis included 2647 children (4.3 0.5 years, 50.6% girls, 49.0% rural).Overall, 81.9% of participants met the restrained sitting guidelines.Odds of meeting the guidelines were 35% lower for children in urban areas and 71% lower for spending 60 minutes or more in a vehicle Every additional hour of physical activity increased the odds of meeting the guidelines by a factor of 1.25.These relationships differed when stratified by country income level.Conclusions: While most children meet the guidelines, a focus on children living in urban areas, spending more time in vehicles, and those who engage in less physical activity is warranted.
