Economic burden of underweight and overweight among adults in the Asia-Pacific region : a systematic review

Abstract

To assess the economic burden of underweight and overweight among adults in the Asia-Pacific region.; Systematic review of articles published until March 2015.; Seventeen suitable articles were found, of which 13 assess the economic burden of overweight/obesity and estimate that it accounts for 1.5-9.9% of a country's total healthcare expenditure. Four articles on the economic burden of underweight estimate it at 2.5-3.8% of the country's total GDP. Using hospital data, and compared to normal weight individuals, four articles estimated extra healthcare costs for overweight individuals of 7-9.8% and more, and extra healthcare costs for obese individuals of 17-22.3% and higher.; Despite methodological diversity across the studies, there is a consensus that both underweight and overweight impose a substantial financial burden on healthcare systems in the Asia-Pacific region
