Objective:
To explore relationships between concerns and physical activity and body mass index (BMI) among a racially/ethnically diverse low-income population.
Method:
A cross-sectional survey documented behavioral risks among racially/ethnically diverse low-income residents in the Boston area (2005-2009). Multivariable logistic regressions were conducted in 2012 for each concern, using SAS version 9.2.
Results:
Those very/moderately concerned about weight were more likely to have higher BMIs, be in the preparation/action stage, received behavioral counseling, participated in a weight management program, and be interested in participating in one in the future. Those very/moderately concerned about physical activity were more likely to have higher BMIs, received behavioral counseling, and participated in a physical activity program.
Conclusion:
Individuals with elevated BMIs or low levels of physical activity are concerned. While level of concern is important, these findings suggest that it is not likely to be a sufficient catalyst to behavior change.
