Barriers to obesity health care from GP and client perspectives in New Zealand general practice: A meta-ethnography review

Abstract

Obesity is a complex international health concern affecting individual quality of life and contributing to an unsustainable strain on national health systems. General practice is positioned as best suited to deliver weight management health care, yet, obesity rates remain high suggesting barriers are experienced within this space. The aim of this review is to synthesize general practitioner and client perspectives of weight management to identify barriers experienced in New Zealand general practice. Six databases were searched resulting in eight articles being included in this review. This interpretive synthesis was guided by principles of meta-ethnography and grounded theory. Four overarching themes were identified from client and general practitioner perspectives: stigma, communication, inadequate health care (system limitations for general practitioners and lack of tailored advice for clients), and sociocultural influences. These four barriers were found to be interdependent, influencing each other outside the general practice context, highlighting the intersectionality of weight management health-care barriers and further complicating effective weight management within general practice. Clients reported wanting tailored, non-stigmatized, effective weight management health care, yet, general practitioners reported being ill-equipped to provide this due to barriers both within and outside the limits of their practice. General practice requires more systemic support to deliver effective weight management including public health campaigns and indigenous health information to reduce health inequities. An appraisal of general practice being “best suited” to deliver effective weight management health care that is culturally appropriate is urgently required to improve obesity related health outcomes in New Zealand.
