Abstract

Overweight, obesity and physical inactivity (PI) are of major public health concern globally and associated with multiple adverse health outcomes. Overweight and obese populations experience diminished health-related quality of life (HRQOL) and greater depression symptoms when compared to their normal weight counterparts. Emerging evidence suggests ‘small changes’ in physical activity can produce positive health benefits. The aim of this study was to investigate the effects of a little physical activity across body mass index (BMI) status on HRQOL and depression outcomes. Secondary data analysis was conducted using
the ‘US 2015 Behavioral Risk Factor Surveillance System’ survey. A total of 4,442 participants with complete and valid responses were included in the analysis. A two-way
MANOVA was conducted with BMI (normal weight, overweight, obese) and physical activity (PI, insufficiently active [IA] < 150 min/week) as independent variables and HRQOL-4 and Patient Health Questionnaire-8 (PHQ-8; depression symptoms) as dependent variables. Statistically significant physical activity main effect revealed the IA groups
reported improvements in general health (‘very good’ versus ‘good’), roughly 6.5 days physical health and 3 days mental health, and PHQ-8 (‘none-to-minimal depression’ versus ‘mild depression’) compared to PI groups (p < .001). The overweight groups had larger improvements across dependent variables (except general health) compared to normal weight and obese groups. These findings add support to the growing small changes research, which suggests engaging in a little physical activity can improve health outcomes in overweight and obese populations.
