Summary

The global obesity epidemic and its adverse health effects have reached sub-Saharan Africa. In some urban settings, like Burkina Faso's capital Ouagadougou, up to 43% of the adult population are overweight or obese. At the same time, modernised food systems are responsible for 26% of global greenhouse gas emissions, 50% of land use and 70% of freshwater use. International guidelines on the treatment of overweight and obesity recommend dietary intervention programmes that promote reduced calorie intake and increased physical activity. So far, weight loss interventions rarely consider sustainable dietary concepts, including healthfulness, affordability, cultural appropriateness and environmental friendliness. Therefore, we conducted a family-based, randomised, controlled trial (RCT) for the effects of a sustainable weight loss intervention on cardiometabolic, environmental, and economic outcomes in urban Burkina Faso.

Methodology

The project consists of three phases: i) formative and co-design phase using qualitative and quantitative methods, incl. in-depth interviews about the perceptions of healthy and environmentally friendly diets as well as exploratory dietary pattern analysis to describe prevailing dietary practices, ii) implementation and impact evaluation of the RCT, comparing a 6-month sustainable dietary weight loss intervention programme (n=125) with standard weight loss information material and 5 min oral counselling (n=125) (intervention phase: 0-6 months; consolidation phase: 7-12 months), and iii) process evaluation, incl. qualitative impact mapping through focus group discussions (FGDs), cost-effectiveness and budget impact analysis.
