Sažetak
Introduction: Physical activity (PA) in childhood is an important determinant of body build and consequent overall health status but various determinants of PA are rarely studied in relation to body built indices in early school-age children. The aim of this investigation was to determine whether children who exhibit PA risk be- haviors differ in their waist circumference as a measure of central obesityMethods: This study uses data from the Childhood Obesity Surveillance Initiative (COSI) 2015/2016 in Croa-tia. The study was conducted in accordance with the COSI-Protocol of the WHO/Europe on children 7-9 years. Sampling was conducted randomly at the national level with class as a sampling unit and the final sample size being 5591 children (response rate 79%). Children’s anthropometric measures were taken in schools by trained examiner teams using standardized equipment. Additional data on children’s sociodemographics and lifestyle habits were gathered from their parents and schools using standardized forms. PA-risk behaviors included five measures: (i) using inactive transportation going to and from school, (ii) going to a sports or dancing club <2h/week, (iii) actively playing outside <1 h/d, (iv) screen time ≥ 2h/d, (v) sleep duration <9h/d]. Differences in waist circumference between children who exhibited certain PA risk behaviors as opposed to those who didn’t were tested using Mann-Whitney tests. Results: Mean waist circumference was 61.51 cm. The highest mean waist circumference was found among children who actively play outside for less than 1 hour a day, 63.32 cm. When looking at the number of exhib-ited PA risk behavior, the highest mean waist circumference was found among children who exhibited 3 out of 5 PA risk behaviors, 63.17 cm. A statistically significant difference in waist circumference was found in 2 out of 5 observed PA risk behaviors – children who actively played outside for less than 1 hour a day (p<0.001) and those who spent more than 2 hours a day in front of the screen (p<0.001) had a higher waist circumference than children who didn’t exhibit those behaviors. No difference was found in regard to using inactive trans-portation going to and from school, sleeping less than 9 hours, and going to a sports or dancing club for less than 2 hours a week. When looking at the number of risk behaviors, children who had exhibited 3 or more risk behaviors had a higher waist circumference than those with 2 or less (p=0.007).Conclusion: Results indicated specific associations between various determinants of PA and waist circumfer-ence as a measure of central obesity in early school-age children. Findings should be directly translated into development of age-specific educational programs where parents should be informed about importance of specific PA-determinants in this age-group.
