Correlates of Weight-Loss Methods Among Young Adults in Canada

Abstract

Objective: The aim of this study was to examine the prevalence of various weight-loss behaviors among young adults in Canada and differences in the use of these methods by demographic characteristics, health literacy, and perceived body size. Methods: Data from the 2016 wave of the Canada Food Study were used, which collected self-reported information from 3,000 young adults in five cities. Linear regression models were conducted to investigate correlates of the number and type of weight-loss methods used across the following four categories: dietary changes, physical activity, assisted weight-loss methods, and unhealthy behaviors. Results: In the past 12 months, more than half of respondents reported a weight-loss attempt, and nearly one-fifth engaged in an unhealthy weight-loss method. The risk of engaging in a greater number of weight-loss behaviors across categories was higher for women, nonbinary-gendered individuals, and individuals who perceived themselves as having overweight or obesity. Respondents with lower health literacy engaged in a significantly greater number of unhealthy methods. Conclusions: Many young adults use healthier weight-loss strategies, but a concerning number use multiple and/or unhealthy weight-loss methods as well. Furthermore, there are subgroup differences in weight-loss method engagement, which holds significance for public health efforts aiming to improve weight-related behaviors.
