Health care cost of overweight-related diseases in Bangladesh

To estimate the economic burden of overweight in Bangladesh. We used data from Household Income and Expenditure Survey, 2010. A prevalence-based approach was used to calculate the population attributable fraction (PAF) for diseases attributable to overweight. Cost of illness methodology was used to calculate annual out of pocket (OOP) expenditure for each disease using nationally representative survey data. The cost attributable to overweight for each disease was estimated by multiplying the PAF by annual OOP expenditure. The total cost of overweight was estimated by adding PAF-weighted costs of treating the diseases. Nationwide, covering the whole of Bangladesh. Individuals whose BMI ≥ 25 kg/m2. The total cost attributable to overweight in Bangladesh in 2010 was estimated at US$147·38 million. This represented about 0·13 % of Bangladesh's Gross Domestic Product and 3·69 % of total health care expenditure in 2010. The sensitivity analysis revealed that the total cost could be as high as US$334 million or as low as US$71 million. A substantial amount of health care resource is devoted to the treatment of overweight-related diseases in Bangladesh. Effective national strategies for overweight prevention programme should be established and implemented.
