Physical Activity Awareness of British Adolescents.

ABSTRACT: OBJECTIVE:To assess adolescent PA awareness and investigate associations with biological and psychosocial factors. DESIGN:Cross-sectional from November 2005 to July 2007 (ROOTS study). SETTING:Population-based sample recruited via Cambridgeshire and Suffolk schools (UK). PARTICIPANTS:N=799 (44% male, 14.5±0.5 years). MAIN EXPOSURES:Self-rated PA perception, self-reported psychosocial factors, measured anthropometry. OUTCOME MEASURE:PA measured using accelerometry over five days. 'Inactive' defined as accelerometry-measured <60 min/day of at least moderate PA (MVPA). Associations between awareness (agreement between self-rated and accelerometry-measured active/inactive) and potential correlates investigated using multinomial logistic regression. RESULTS:70% of adolescents were inactive (81% of girls, 56% of boys, OR(95% CI) 3.41(2.41, 4.82)). 53% of all girls (63% of inactive girls) and 34% of all boys (60% of inactive boys) inaccurately rated themselves as active (over-estimators). Compared to girls accurately describing themselves as inactive (29%), girl over-estimators had lower fat mass (OR(95% CI) 0.84(0.70, 0.99)), higher SES (high vs. low 2.4(1.07, 5.32)), reported more parent-support (1.57(1.12, 2.22)) and better family relationships (0.25(0.09, 0.67)). Amongst boys accurately describing themselves as inactive (22%), over-estimators had lower fat mass (0.86(0.77, 0.96)) reported more peer-support (1.75(1.32, 2.30)) and less teasing (0.75(0.61, 0.92)). CONCLUSIONS:A substantial number of adolescents believe themselves to be more physically active than they really are. They maybe unaware of potential health risks, and may be unlikely to participate in PA promotion programs. Increasing information of PA health benefits beyond weight control might help encourage behavior change.

Project description:BACKGROUND:Physical activity (PA) in adolescence is crucial for lifelong healthy lifestyle, and attention is needed to adolescents at health risk due to insufficient PA. This study investigates the composition of weekly PA in adolescents by PA level and provides a rationale for change in their lifestyles. METHODS:The research was conducted at 66 schools in Poland between 2009 and 2016, among 949 girls and 650 boys aged 15-18?years. We used pedometers to monitor weekly PA with data assessed using the Indares web app. The participants were split into three groups by mean daily step count (lower, < 9000; middle, 9000-12,999; and higher, ? 13,000 steps/day), as a reliable and non-expensive indicator of PA. RESULTS:We did not observe statistically significant differences in composition of 7-day PA between participants with varying levels of PA, regardless of their gender (F(12,9558)?=?0.60; p?=?0.841; ?p2?>?0.000). The smallest differences in daily step counts by PA level were found on Mondays and the biggest on Fridays and Saturdays, in boys and girls; the differences between average school and average weekend days were most pronounced in less active girls (1677 steps/day) and boys (1886 steps/day). During the school week, the highest proportion of less active girls met the 11,000 steps/day recommendation on Fridays (21.9%), statistically significantly less than on other school days (p?<?0.001). Similarly, less active boys (22.2%) had significantly less activity on Fridays than on other school days, except for Mondays (p?=?0.143) Analogous pattern was apparent also in more active adolescents. CONCLUSIONS:Less active adolescents have comparable composition of weekly PA to the more active ones but they can hardly meet the generally accepted PA recommendations. Better understanding of weekly PA composition and rates of meeting PA recommendations by day of the week can lead to more efficient interventions improving lifestyles. The recommendation of 9000 steps/day most days of the week, thus, appears appropriate for less active adolescents, as a motivating achievable goal.
