Physical activity is associated with depression and depressive symptoms in US adults with diabetes: a cross-sectional study

< 0.05) were found. Greater incidence of major depression, depressive symptoms and greater depression scores in the PHQ-9 were found for inactive diabetes patients. Correlations of PA group and METs with PHQ-9 scores and the frequency of depressive symptoms for each item of the PHQ-9 were found, except for the 7th item (concentration problems). Increased odds of suffering major depression (OR = 1.957 (CI95% = 1.310-2.923)) and all the depressive symptoms studied were found for physically inactive diabetes patients compared to those from the moderate PA group. The association of PA with depression and the frequency of suffering depressive symptoms in US adults with diabetes were confirmed. Greater prevalence of depression and greater frequency of depressive symptoms were found for physically inactive diabetes sufferers. A dose-response relationship between PA and frequency of depressive symptoms is suggested.
