An exploration of extreme obesity and weight loss management for adults in rural, remote, and regional areas: a systematic review

Abstract

Background

Extreme obesity is a global health issue impacting health and related health outcomes. Although extreme obesity is prevalent across all geographical settings, the condition is more common in geographically isolated locations. The success of mainstream weight loss strategies such as surgery, exercise, and dietary information within these communities remains unknown, and it is unclear if isolation facilitates or hinders treatment for weight management.

Aim

This review aimed to identify common themes around weight loss and health and social impacts for extremely obese adults living in rural, remote, and regional locations.

Methods

A systematic literature review of peer-reviewed publications from May 2013 to May 2023 was undertaken and appraised using the Mixed Method Appraisal Tool (MMAT). Sequential synthesis was thematically analysed and described within a narrative account. Earlier dates were not included as initial research indicated a global surge in obesity within the early 2010s (Wang, Y., Beydoun, M. A., Min, J., Xue, H., Kaminsky, L. A., & Cheskin, L. J. (2020). Has the prevalence of overweight, obesity and central obesity levelled off in the United States? Trends, patterns, disparities, and future projections for the obesity epidemic. International Journal of Epidemiology, 49(3), 810–823) and a surge in bariatric treatments for the management of extreme obesity was noted around the same time (Mocanu, V., Dang, J. T., Sun, W., Birch, D. W., Karmali, S., & Switzer, N. J. (2020). An evaluation of the modern North American bariatric surgery landscape: current trends and predictors of procedure selection. Obesity Surgery, 30, 3064–3072).

Results

This review identified 13 studies that reported negative trends in extreme obesity for isolated locations linked to gender, culture, and poor mental health. Individualised and community models of weight loss support can be positive for certain demographic groups, specifically females, through the promotion of cost-effective, and locally available traditional food choices.

Conclusion

Living with extreme obesity within geographically isolated locations and losing weight is challenging for women, Indigenous peoples, and people with low literacy and those from lower socio-economic backgrounds. Generalised advice about weight loss is often unsuccessful; however, weight loss is achievable with consumer engagement which considers the influence and impact of rurality. Further research focusing on individualised nursing models for managing morbid obesity within isolated locations is required.
