Summary: Globally, the literature tends to emphasize negative associations between socioeconomic status (SES) and bodyweight in countries improving their economic development. However, little is known about the social distribution of obesity in sub‐Saharan Africa (SSA) where economic growth has been highly heterogeneous the last decades. This paper reviews an exhaustive set of recent empirical studies examining its association in low‐income and lower‐middle‐income countries in SSA. Although there is evidence of a positive association between SES and obesity in low‐income countries, we found mixed associations in lower‐middle‐income countries, potentially providing evidence of a social reversal of the obesity burden.

SUMMARY This comparative study examines the relationship between excess weight and hourly wages in the unprecedented context of middle‐income countries. We compare three countries that are at different stages of the nutrition transition: India (at an early stage), China (at an intermediate stage) and Mexico (at an advanced stage). To do so, we use three distinct household surveys and combine different estimation procedures. Our results emphasise a wage penalty of underweight together with a wage reward of excess weight in India, pointing towards the persistence of pro‐fat social norms in a country where hunger is still highly prevalent. Conversely, we observe significant overweight and obesity wage penalties in China, especially in non‐manual jobs, probably due to a large diffusion of anti‐fat social norms in a country where hunger is residual and normal weight predominant. In Mexico, we find an overweight wage premium in manual jobs and no effect in non‐manual jobs. We speculate that the large‐scale diffusion of excess weight may lead to its greater social acceptance (i.e. 'new' pro‐fat norms). Finally, we explore the potential transmission channels through which bodyweight may affect wages. We provide evidence of potential anti‐fat discrimination in China and pro‐fat‐discrimination in India and Mexico. Our results have important implications in terms of public health policy.
