Healthy eating strategies for socioeconomically disadvantaged populations: a meta-ethnography

Purpose: In developed countries, diet-related health inequalities between people with different levels of socioeconomic advantage persist. However, there is limited qualitative evidence to inform the design of effective healthy eating (HE) strategies in socioeconomically disadvantaged populations (SDPs). The purpose of this review was to explore the characteristics influencing HE strategies for SDPs and develop a new understanding of how and why they influence their success.Methods: A qualitative evidence synthesis using a systematic meta-ethnographic approach. The twelve studies included were conducted in the USA, Canada, Australia, and UK.Results: The studies described a range of HE strategies, including nutrition education programs, food vouchers, and community gardens. Personal values and sense of pride and autonomy were found to have an influence on participants’ attitudes towards HE strategies. Similarly, social characteristics such as level of social support and opportunities for shared benefits influenced participants’ engagement. Structural characteristics such as the affordability and accessibility of healthy foods determined strategy acceptability and success.Finally, organizational characteristics such as flexibility influenced how well strategies supported the circumstances of participants.Conclusions: These overlapping characteristics may be used to inform the development, implementation, and evaluation of strategies to improve healthy eating in SDPs
