A systematic review of patient barriers and facilitators for implementing lifestyle interventions targeting weight loss in primary care

Abstract

SummaryNumerous barriers are experienced by people with overweight and obesity that play a role in the implementation of lifestyle interventions. This systematic review aims to investigate the barriers and facilitators for children and adults with overweight or obesity when implementing lifestyle interventions targeting weight loss in primary care. A systematic review was conducted by searching four databases to identify eligible studies (1969–2022). The Critical Appraisal Skills Program was used to assess the study quality. A total of 28 studies were included, of which 21 focused on adults and seven on children and their parents. Thematic synthesis of the 28 studies included identified nine key themes, of which support, role of the general practitioner, structure of the lifestyle intervention program, logistics, and psychological factors were the most common. This review shows that a strong support system and a personalized lifestyle intervention are essential components for successful implementation. Additional research is needed to identify whether future lifestyle interventions can take these barriers and facilitators into account and still be feasible for losing weight.
