Sažetak
Aim: the aim of this study was to explore associations of different types of sedentary behavior with blood pressure and waist circumference in 15-year old adolescents Methods This investigation is a part of the CRO-PALS study which is an observational longitudinal study conducted in a representative sample of urban youth in Zagreb (Croatia ) Participants CRO-PALS involves 903 adolescents and for the purpose of this study data from 836 participants (mean age [SD]=15.6[0.3] years) Measurements: Average amount of sedentary behaviours(SB) on school days and weekends was collected using the SHAPES questionnaire blood pressure (BP) & waist circumference (WC) were measured using standard procedures. SB were subdivided into screen time(ST), doing homework and studying and other SB (e.g. reading, playing instruments, listening to music) Time spent in all SB was summed to get total sedentary time. Statistical procedures Associations of various types of SB with BP and WC were analyzed with multiple linear regression adjusting for school type, maturation, height and socio-economic status and. All analysis were stratified by sex Results Neither total SB, nor any type of SB was significantly related to blood pressure or waist circumference in either sex . Borderline significant associations were noted for: a)screen time and systolic blood pressure in girls (p=0.06) and b)homework and diastolic BP in boys (p=0.08) and homework and waist circumference in both sexes (p=0.05 and p=0.09 for boys and girls, respectively). Nevertheless, the effect sizes were not clinically meaningful – 2 1 / 2 hours of screen time / day were associated with 1 mmHg higher systolic BP and – 100 min / day of studying were accompanied by 1 mmHg higher diastolic BP – Similarly, a 1 cm increase in WC was related to 120 and 100 min/ day of studying in girls and boys, respectively Conclusion This study did not show any significant associations between total and different types of sedentary behavior with blood pressure and waist circumference in 15- year olds.
