Obesity management from the perspectives of people living with obesity in Canada: A mixed-methods study

Abstract

Aims: To identify and better understand themes related to why people living with obesity (PwO) in Canada may not use professional support and to explore potential strategies to address the challenges. Methods: One-on-one interviews and online surveys, informed by the Theoretical Domains Framework, were conducted. A total of 20 PwO were interviewed and a separate group of 200 PwO were surveyed. Results from the interviews guided the development of the survey. Spearman's correlation analysis was performed to investigate the association between the theme domain scores of the PwO and their prior experience with obesity management strategies. Results: The 200 PwO surveyed provided representation across Canada and were diverse in age, background and gender. The most prominent domains associated with use of professional support by PwO were: Intention (rs = −0.25; p < 0.01); Social/Professional Role and Identity (rs = −0.15; p < 0.05); and Optimism (rs = −0.15; p < 0.05). For example, PwO without professional support less often reported being transparent in obesity discussions, perceived obesity to be part of their identity, and expected to manage the illness long term. Many PwO hesitated to use various adjunctive therapies due to concerns about affordability, long-term effectiveness, and side effects. Conclusion: This study identified contextual, perception and resource considerations that contribute to healthcare decision-making and the use by PwO of professional support to manage obesity, and highlighted key areas to target with interventions to facilitate obesity management. Strategies such as consistent access to healthcare support and educational resources, as well as improved financial support may help PwO to feel more comfortable with exploring new strategies and take control of their healthcare.
