An update on the economic burden of type 2 diabetes mellitus in China

Objectives This study aims to update the statistics on the economic burden of T2DM and to identify the factors affecting the economic costs of T2DM in China. Methods This study conducts a systematic review of the existing literature that has reported on the direct economic costs (mainly the direct medical resource consumption) and indirect economic costs (mainly non-medical costs and intangible costs) of T2DM as of 31 May 2019. Results The total expenditure on diabetes in China's western region is still relatively low. Additionally, the mean direct costs of T2DM are high in China's northern urban areas. However, compared to urban areas, in rural areas, the largest proportion of the total economic costs of T2DM is the mean indirect costs. Furthermore, age, sex, type and number of complications, type of medical insurance, diabetes duration, level of education, and income are the primary factors that influence the economic burden of T2DM. Conclusion There is a considerable economic burden associated with T2DM in China. Therefore, to address the economic burden of T2DM, it is vital to take measures to reduce the prevalence rate of diabetes.
