Background
Lifestyle drift is a phenomenon wherein the focus of interventions aimed at improving health and decreasing health inequities that start with the intention of acting on upstream social determinants of health inadvertently drift downstream towards interventions targeting individual health behaviours. While lifestyle drift has been referred to in a growing body of literature, as far as we are aware, there is not currently any scoping or systematic reviews that examines the concept of lifestyle drift. The objective of this scoping review is to summarize the existing literature on lifestyle drift, describe how it is defined in the literature, the causes or mechanisms of influence that lead to lifestyle drift and ways to address it.
Methods
A comprehensive search strategy was developed with guidance from a librarian and seven databases were searched. Title and abstract and full text screening was conducted in Covidence according to inclusion and exclusion criteria. Included documents were imported into NVivo, and data from articles were analysed using a thematic analysis approach.
Results
We identified 318 articles through the initial search strategy. After title, abstract and full text screening, we charted data from 32 articles which included lifestyle drift as either a focus or a major theme. Definitions of lifestyle drift included some common elements as well as some variability of concepts. Neoliberalism and the biomedical model were frequently identified as drivers of lifestyle drift across articles. While many strategies to counteract lifestyle drift were proposed, applying a health in all policies approach, and participation from priority populations were the most common strategies suggested.
Conclusion
This scoping review identified that while lifestyle drift is a concept increasingly referred to in public health, health promotion and chronic disease prevention, there remains a need for more empirical research on lifestyle drift, including research that elucidates the mechanisms that contribute to it. If public health initiatives indeed want to focus on upstream interventions that intend to have broad impact and reduce health inequities, perhaps most importantly, research regarding how to identify, prevent and address the phenomenon of lifestyle drift may support these goals.
