Abstract

Abstract: Background: Obesity and overweight are a global public health problem causing several chronic diseases which can lead to various degrees of morbidity and mortality. These medical conditions cause economic costs and complications. The purpose of the present study to estimate the direct and indirect costs incurred by obese and overweight patients with non-invasive treatments in Tabriz, north-western Iran. Method: The number of 247 patients were studied by cross-sectional approach and used cost of illness's prevalence approach assessing the total costs (direct and indirect) of obesity and overweight through interview and assessing relevant clinical records. The study conducted over three months from December 2018 to February 2019 in Tabriz, capital of East Azerbaijan province, Iran. Direct costs included hospitalization, para-clinical medications and outpatient visits for treatment of obesity and overweight. Loss of productivity, days of restricted activity and days in bed, cost of wasting time, transportation costs and nursing expenditure were estimated as indirect costs in the present study. For estimating direct and indirect costs, we used the bottom-up costing approach. The foreign exchange rate used in the analysis was 42000 Iranian Rial = 1US$ (December-February 2018). Results: The mean three months cost per patient is 38529697 IRR (equivalent to $91.73 USD), Direct medical costs have a most significant part of total costs with 36765292 IRR (87.53USD) per three months (95%). Direct non-medical costs were 1380484 IRR (3.28USD) per patient (4%) analysis of variance showed that there was a significant difference between the four strategies in three months. Among the therapeutic strategies, the most changes in body mass index (BMI) occurred in patients who used Basic diet with several types of medicines strategy (p<0.001). Tukey post hoc showed BMI Changes in a patient with a Basic diet with herbal remedies was minimum (p<0.001). According to results in the first month, BMI has a significant reduction over three months. Regarding costs, the analysis showed that Patients who used the Basic diet strategy incurred the lowest costs (p<0.001) and the highest costs are related to patients with a Basic diet with several types of medicines (p<0.001). Conclusion: The results of the present study are useful in improving health policymakers and researchers in motivating to do more studies in particular for adopting new policies depending on the level of insurance coverage and their problems which patients deal with during the treatment period.
