Secular and longitudinal physical activity changes in population‐based samples of children and adolescents

Abstract

The aims of this study were to investigate whether physical activity (PA) and sedentary time (ST) in 9-and 15-year-olds differed between 2005-2006 and 2011-2012 (secular change), and to investigate changes in PA and ST from age 9 to 15 (longitu- decline in PA in the participants followed longitudinally from age 9 to 15 years.

Comparisons of pedometer‐determined weekday physical activity among Swedish school children and adolescents in 2000 and 2017 showed the highest reductions in adolescents

“…Dalene et al. produced similar results to us, reporting negative temporal trends in physical activity, which they attributed to less active transportation to and from school, increased screen‐based sedentary behaviour and decreased leisure activities and organised sports.…”

“…Furthermore, a study by Dalene et al. showed that sedentary time among 9‐ and 15‐year‐olds increased from 2005–2006 to 2011–2012. At the same time, their levels of light physical activity, which is the level below moderate‐to‐vigorous physical activity, had decreased by approximately 30 minutes per day.…”

Prevalence of underweight, overweight, and obesity in children and adolescents with type 1 diabetes: Data from the international SWEET registry

“…Type 1 diabetes and its treatment therefore appear to promote excess weight gain. Several factors, which are common in adolescents with or without T1D, such as sedentary behavior, reduced exercise (especially in females), and unhealthy eating habits, may contribute to favor a positive energy balance . Other factors favoring body fat accumulation are specific to diabetes, including extra calorie intake to prevent or correct hypoglycemia, the consumption of low carbohydrate high fat foods, to reduce postprandial glucose increase, and the chronic exposure of the peripheral tissues to non‐physiologic hyperinsulinemia due to the subcutaneous insulin injections or infusion via insulin pump .…”

Participation in organized sports is associated with decreased likelihood of unhealthy lifestyle habits in adolescents

“…National and international guidelines recommend that children and adolescents engage in regular physical activity, of moderate‐to‐vigorous intensity, for at least 60 minutes per day; however, many adolescents do not meet this quantity or quality . OSP has the potential to help adolescents establish lifelong, healthy physical activity patterns .…”
