The epidemiology of muscle-strengthening activity among adolescents from 28 European countries

Abstract

Aims: This study aimed to describe the prevalence and socio-demographic and lifestyle-related correlates of muscle-strengthening activity (MSA; strength/resistance training, sit-ups/push-ups, etc.) among a large sample of European adolescents. Methods: Data were drawn from the European Health Interview Survey Wave 2 (2013–2014), including 8818 adolescents (15–17 years) from 28 European countries. Self-reported MSA was assessed using a previously validated survey item. Population-weighted prevalence ratios were calculated for (a) ‘none’ (0 days/week), (b) ‘insufficient MSA’ (1–2 days/week) or (c) ‘sufficient MSA’ (⩾3 days/week). Generalised linear models using Poisson regression with robust error variance were used to calculate the prevalence ratios for adolescents reporting sufficient MSA by socio-demographic/lifestyle characteristics and by European region. Results: Overall, 19.4% (95% confidence interval (CI) 18.3–20.7) reported sufficient (⩾3 days/week) MSA and 57.9% (95% CI 56.4–59.6) reported none. Females, adolescents from Southern and Eastern European regions, those not meeting the aerobic guideline and adolescents classified as overweight were significantly associated with a lower likelihood of reporting sufficient MSA, independent of other characteristics. Conclusions: The majority of European adolescents do not meet the MSA guidelines. Future large-scale MSA public-health interventions should target female and currently inactive adolescents, as well as those from Southern and Eastern European regions.
