Research Paper Title
Population-wide Weight Loss and Regain in Relation to Diabetes Burden and Cardiovascular Mortality in Cuba 1980-2010: Repeated Cross Sectional Surveys and Ecological Comparison of Secular Trends.
Did the pattern of population-wide weight loss and regain in Cuba during and after the economic crisis of the 1990s result in changes in the burden of diabetes and cardiovascular disease?
The 1990s economic crisis in Cuba resulted in an average weight loss of 5.5 kg in the population, accompanied by rapid and substantial declines in the rates of diabetes and heart disease. As the economy recovered obesity and diabetes rates rebounded promptly and diabetes mortality increased, while the decline in cardiovascular disease slowed.
What is Known and What this Paper Adds
Abrupt reductions in diabetes and cardiovascular death have been observed during food shortages in economically developed societies – primarily during the second world war – although no population-wide information was available on trends in weight, physical activity or diabetes incidence or prevalence. Population-wide weight loss and regain in Cuba was found to be associated with improvements and declines in health burden, respectively.
