Objective. To evaluate the differences between smokers and non-smokers with type 2 Diabetes Mellitus (T2DM) in anxiety, depression and quality of life; assess whether anxiety and depression moderate the association between quality of life and tobacco use; and evaluate the level of prediction of the quality of life towards tobacco consumption. Methodology. 44 smokers and non-smokers with T2DM. Information on the pattern of consumption, nicotine dependence, anxiety, depression, and quality of life was collected. Results. Anxiety as a trait and depression as a trait and state moderate the association between the pattern of consumption and quality of life. Conclusions. Smokers with DM had more symptoms of depression and anxiety and were more affected in quality of life. Anxiety and depression moderate the association between quality of life and nicotine dependence. The importance of taking these moderating factors into account in interventions for stop smoking and the maintenance of tobacco abstinence in people with T2DM is highlighted.
