Background: Screen time (including TV viewing/computer use) may be adversely associated with metabolic and mental health in children. Purpose: To describe the prevalence and sociodemographic correlates of screen time in an international sample of children aged 4–17 years. Methods: Data from the International Children’s Accelerometry Database were collected between 1997–2009 ...
Purpose: To examine the associations between objectively measured physical activity (PA), sedentary time, and health-related fitness; and to investigate the combined association of PA and sedentary time on health-related fitness in youth. Methods: PA and sedentary time were assessed with accelerometers in 2506 youth aged 10-18 years (M age=13.2+/-2.3). Participants ...
Background: There is some evidence that physical activity (PA), sedentary time and screen time (ST) are associated with childhood obesity, but research is inconclusive and studies are mainly based on self-reported data. The literature is dominated by data from North American countries and there is a shortage of objective data ...
Introduction: The association between habitual sleep patterns and cardiac autonomic modulation (CAM) in adolescents is not fully understood. We investigated such association in the population-based Penn State Child Cohort (PSCC) follow-up examination. Methods: An actigraph (GT3X) and a sleep diary were used in 421 adolescents for 7 consecutive nights to calculate ...
Introduction: The association between habitual sleep patterns and nutrition intake is not fully understood, especially in adolescents. We investigated the association between habitual sleep duration and its variability with nutrition intake in population-based adolescents of the Penn State Child Cohort (PSCC) follow-up examination. Methods: An actigraph (GT3X) and a ...
Introduction: Chronic sleep problems in adults have been associated with abdominal obesity and cardiometabolic disorders. However, associations between habitual sleep patterns and central obesity have not been fully understood, especially in adolescents. We investigated the associations between habitual sleep duration and its variability and body fat distribution in population-based adolescents ...
Introduction: Night-to-night variability of sleep variables derived from actigraphy or sleep diary data appears to be a novel risk factor associated with physical and mental health. However, little is known about factors associated with night-to-night sleep variability. The aim of this study was to assess the association of sociodemographic and ...
Introduction: Childhood obesity is a consequence of environments that disrupt the balance of energy intake and energy expenditure. Obesogenic environments consist of social norms and environmental factors that facilitate unhealthy behaviors around diet and physical activity. Nutritional knowledge and physical activity are cornerstones of every obesity treatment. The aims are ...
Abstract Introduction: Some of the chronic diseases that appear in adulthood are developed in childhood stage. There are few studies investigating the association between physical activity (PA) and cardiovascular and metabolic disease risk markets using objective measurement for apparently healthy adolescents. Aim: The primary aim of the study was to ...
Introduction: Prevalence of overweight and obesity, highly sedentary behaviors (SB) and a lack of physical activity (PA) among young children and adolescent are a major public concern. They are important risk factors for many chronic diseases such as diabetes, and cardiovascular disease. However evidence has shown that most children and ...
