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 ...
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 ...
Aim: Abdominal obesity, a status of excessive accumulation of both central subcutaneous and visceral fat, has emerged as an main predictor for metabolic complications and adverse health effects. Waist-height ratio (WHR) is simple, yet effective, surrogate measures of abdominal obesity and may be good predictor of cardiovascular disease risk in ...
Purpose: The study of children’s free-living cadence (steps/min) is possible using accelerometers capable of recording minute-by-minute step data monitored over several days. The objective of this study was to determine free-living accelerometer- determined time at or above GAITRite-assessed individualized normal cadence in children categorized by BMI as normal ...
Purpose: To examine the cross-sectional associations of objectively derived physical activity and sedentary time with cardiometabolic biomarkers, including the potential collective impact of shifting time use from less towards more active behaviors. Methods: Overweight/obese and/or physically inactive adults with type 2 diabetes (n=294; mean age = 58.0 [SD 8.5] years) wore Actigraph ...
Purpose: To examine whether change in SB and PA associated with a change in weight status over 24-months. Methods: Data were from Identifying Determinants of Eating and Activity (IDEA), a 3-year longitudinal cohort study that assessed the etiology of adolescent obesity. PA and SB were assessed using the ActiGraph (Model 7164; ...
Background: The effects of physical activity (PA) in producing weight loss are well known. However, there is some controversy about the relationship between PA intensity and levels of obesity in children. Further, different cut-offs have been used to classify obesity, which may influence the observed associations with PA. The ...
Purpose: We compared physical activity (PA) barriers in overweight/obese and healthy weight seven to ten year olds. A secondary purpose was to evaluate the relationship between the number of barriers reported and minutes of moderate-to-vigorous physical activity (MVPA). Methods: :Currently, 19 participants have completed the study. Height and weight were ...
Background: Obesity has been a significant public health concern among US adults. Recently, a great attention has been given to the sedentary behavior (SB) in relation to obesity; however, controversial results have been reported due to the use of less accurate measures of SB and obesity in adults. Purpose: ...
Background: Accelerometry paradata (administrative data related to collection/management/treatment) are inconsistently reported or limited to accounts of valid days and average wear time. Purpose: To present a model for reporting accelerometry paradata collected from children (mean age 10 years) at the Baton Rouge, USA site of the International Study of ...
