Abstract


Background: Obesity continues to be a public health concern given its association multiple comorbidities spanning both physical and mental health. Researchers have documented that both increased Body Mass Index (BMI) and centrally patterned obesity (i.e., waist circumference) are independently associated with health. As such, national health organizations (e.g., Health Canada) have identified an obesity health-risk classification system based on a combination of BMI and waist circumference scores.
Purpose: The objective of this non-experimental study was to examine differences in physical activity and sedentary behaviour in community-dwelling adults who differ in terms of their obesity related health risk classification.
Methods: Participants (N = 50; Mage = 38.50 years, SDage = 14.21 years) BMI and waist circumference scores were measured resulting in the following groups based on obesity-related risk classifications: (a) Least, (b) Increased, or (c) High. Following assessment of anthropometric variables, each participant was asked to wear a SenseWearTM Armband across a seven day monitoring period and scores recorded for active energy expenditure, step count and sedentary behaviour.
Results: A significant multivariate effect (Pillais = .40, F(6, 86) = 3.60, p = .003, ?p2 = .20, observed power = .94) was noted across risk classification groups. Differences were found in the amount of time spent in active energy expenditure for bouts of ten minutes or more (p = .002); specifically between those classified as Least versus High Risk (p < .05).
Conclusion: Participation in active energy expenditure in bouts greater than or equal to ten minutes should be promoted as a parameter for influencing obesity-related ill health in order to allow adults to reach optimal health benefits and reduce their risk.
