A qualitative study of perceived barriers and facilitators to interrupting sedentary behavior among adults living with obesity.

INTRODUCTION: Both obesity and sedentary behavior (SB) are associated with negative health consequences including cardiovascular disease, diabetes, certain cancers and all-cause mortality. To date, perceived barriers and facilitators to interrupting SB in adults living with obesity have not been identified.

OBJECTIVE: This study aimed to identify these perceived barriers and facilitators by conducting a behavioral analysis underpinned by the theoretical domains framework (TDF) and the Capability, Opportunity, Motivation-Behavior (COM-B) model to enhance knowledge and inform future intervention development.

METHODS: A purposive and snowball sample ( N  = 21) of adults living with obesity took part in semi-structured interviews, guided by the TDF, to investigate perceived barriers or facilitators to interrupt SB. Transcribed interviews were inductively coded using reflexive thematic analysis. Key themes and subthemes were generated by grouping similar and recurring codes. Finally, subthemes were mapped to the TDF and COM-B.

RESULTS: Five key themes were identified, which influence SB across all domains of living. These relate to (i) physical and mental wellbeing; (ii) motivational readiness; (iii) roles, responsibilities and support; (iv) weight bias and stigma; and (v) the environment. These themes were then deductively mapped to all 14 TDF domains and all six of the COM-B constructs.

CONCLUSION: A complex interplay of individual, societal and policy factors contributes to the development and habituation of SB patterns in adults living with obesity. Factors identified in this study could assist in the development of interventions, strategies and policies designed to interrupt or reduce sedentary behavior in this population.
