ABSTRACT
Both the increasing prevalence and growing burden of diabetes mellitus have caused global public health concerns. With the development of bio-psycho-social medical model, the impact of psychosocial factors on diabetes has attracted more attentions among the researchers. This paper summarizes findings from epidemiological studies that focusing on the association between diabetes and related psychosocial risk factors. Foreign studies have shown that psychological factors are closely related to diabetes, but the conclusions on social factors are inconsistent. Domestic studies have only targeted on small-sample-sized and cross-sectional studies. More longitudinal research is needed to confirm the impact of psychosocial factors on the risk of diabetes.
