More obesity among the less educated in rich countries
The researchers collected data on 412,921 people from 70 countries between 2002 and 2013. GDP was used as a measure of economic development, and country-specific differences in education were used when considering the assembled data.
The data showed in countries with higher GDP, people less education had higher incidence of obesity. In the countries with lower GDP, however, the data showed people with more education had higher rates of obesity. The association was found to be stronger among women than men. Researchers did not factor gender into the analysis, though they proposed that different educational backgrounds, and different norms and ideals in their countries, may play a role.
The researchers also noted the study does not show causality. In addition to being unsure of the effects of other causes, the researchers also said they were unsure whether GDP and education cause obesity or vice versa. They said, however, that obesity and health education should be receive more attention in developing countries.
The study is published in the Journal of Epidemiology and Community Health.
