Abstract
The goal of this study was to examine use of weight control strategies in Canadian adults and the role of income as a barrier to using these strategies.Data from the Canadian Community Health Survey cycle 4.1 on health behaviour change was used for this study. Analysis was restricted to adults (18+ years) residing in the 10 provinces of Canada. Respondents were categorized as having used weight control strategies in their lifestyle if they responded that they increased exercise, improved/modified their eating habits, or lost weight in the previous 12 months, as the primary means of health improvement. An adjusted household income ratio divided into deciles was used as a measure of income. Multivariable logistic regression was used to examine the relationship between income and weight control strategies adjusting for known confounders.Of the 103,990 respondents analyzed, 60% were overweight or obese and 45% reported using weight control strategies in the previous 12 months. Age, sex, ethnicity, having a regular doctor, education, and income were all significantly associated with using weight control strategies in the multivariable model. Results that included all two- and three-way interactions between sex, weight category, and income found that lower income was significantly associated with using fewer weight control strategies--more so for obese men and normal weight women.Efforts must be made to create equal access to services and food products that promote weight reduction or control strategies given the rising prevalence of adult obesity in Canada.
