Frequency and duration of vigorous physical activity bouts are associated with adolescent boys' bone mineral status: A cross-sectional study

The purpose of this cross-sectional study was to examine the associations between active commuting behavior, levels of physical activity and distance to school in 9–10 year old children. Participants were children (n = 1824) who took part in the SPEEDY study (Sport, Physical activity and Eating behavior: Environmental Determinants in Young people). For both boys and girls, significant positive associations were observed between walking to school and physical activity and moderate-to-vigorous physical activity during weekday journey times (8–9am and 3–4pm), and the size of association also became stronger with increasing distance from school. Promotion of active commuting to school might be an important way to increase levels of physical activity in school children.

Objective: Quantify inequalities in self-reported moderate-to-vigorous physical activity (MVPA) in England and the United States (US). Design: Population-based cross-sectional study. Participants: 4019 adolescents aged 11-15 years in England (Health Survey for England 2008, 2012, 2015) and 4312 aged 12-17 years in the US (National Health and Nutrition Examination Survey 2007-16). Main outcome measures: Three aspects of MVPA: (1) doing any, (2) average min/day (MVPA: including those who did none), and (3) average min/day conditional on participation (MVPA-active). Using hurdle models, we quantified inequalities (average marginal effects: AMEs) using the absolute difference in marginal means. Results: In England, adolescents in high-income households were more likely than those in low-income households to have done any formal sports/exercise in the last seven days (boys: 11%; 95% CI: 4% to 17%; girls: 13%; 95% CI: 6% to 20%); girls in high-income households did more than their low-income counterparts (MVPA: 6 min/day, 95% CI: 2 to 9). Girls in low-income households spent more time in informal activities than girls in high-income households (MVPA: 21 min/day; 95% CI: 10 to 33), whilst boys in low-income versus high-income households spent longer in active travel (MVPA: 21 min/week; 95% CI: 8 to 34). In the US, in a typical week, recreational activity was greater among high-income versus low-income households (boys: 15 min/day; 95% CI: 6 to 24 min/day; girls: 19 min/day; 95% CI: 12 to 27). In contrast, adolescents in low-income versus high-income households were more likely to travel actively (boys: 11%; 95% CI: 3% to 19%; girls: 10%; 95% CI: 3% to 17%) and do more. Conclusions: Policy actions and interventions are required to increase MVPA across all income groups in England and the US. Differences in formal sports/exercise (England) and recreational (US) activities suggest that additional efforts are required to reduce inequalities.

This paper highlights the findings of a comparative cross-sectional study in the cantons of Uri (UR) and Schwyz (SZ). In this study, participating in sports and daily physical activity among 5th grades were observed trough selected indicators. The study was conducted in autumn 2012 and 2013 and included a randomly selected sample of 161 pupils in Uri (10.6±0.7 year olds) and 261 pupils in the canton of Schwyz (10.7±0.7 year olds). In both regions, a high rate of participation in free time sports activities could be detected: 68.8% (UR) and 70.1% (SZ) of all the children involved are members of a sports club, with more than half of them, being active, both in and outside of sports club. The proportion of completely inactive children lies below 5%. Furthermore, exercise and sports are regarded as the most important free time activities (regardless of gender and nationality). The majority of children (UR: 73.4%; SZ: 91%) commuted actively to school, with a significantly higher proportion amongst pupils in the canton of Schwyz (p < 0.001) due to the shorter distances. In total, slightly more than the half of the children reached the official recommendations of at least 60 min. of moderate to vigorous physical activity per day. There was no association between the pedometer-based daily activity and the use of media.
