The lived experience of food insecurity among adults with obesity: a quantitative and qualitative systematic review

Abstract

Background Food insecurity and obesity are increasing both globally and in the UK. In this review we systematically assess the lived experiences of people with obesity who are food insecure and often turn to food banks. Methods We systematically searched electronic databases from January 2007 until October 2022. Data from eligible studies were extracted and the studies assessed for quality. Thematic analysis and narrative synthesis approach was used to analyse the extracted data. Results Six themes were identified among 25 included studies, including: the financial cost of food; psychological aspects related to food insecurity; geographical access and the food environment; food practices in the home; experience of food assistance; and parental-child relationships. The cost of healthy food and psychological factors were identified as key driving factors of the relationship between food insecurity and obesity. Psychological factors such as depression, low self-esteem and stress played an important part in the lived experience of people with obesity and food insecurity. Conclusion The food environment provides context in which food decisions are made, therefore, systems change is necessary to ensure families can afford the food that enables a healthy diet. For clinicians, identification, and attention to the impact of food insecurity on people with obesity are important.
