The most common concordant comorbidity was hypertension while depression was the most common discordant condition .
Adherence to medications was the most frequent diabetes self-care behavior reported and tended to be higher among concordant comorbidities .
The findings showed mixed results concerning the effect of some concordant comorbidities such as hypertension , hyperlipidemia , retinopathy , and heart failure on diabetes self-care behaviors .
But , there is agreement across studies that diabetes-discordant comorbidities have a more detrimental effect on self-care behaviors .
Conclusions : Concordant comorbidities may improve diabetes self-care , but the evidence is inconclusive .
Background : Most patients with Type 2 diabetes ( T2D ) have high number of comorbid chronic conditions that can affect their self-care abilities .
Guidelines for diabetes self-care behaviors are disease specific with little attention given to managing T2D with other comorbidities .
Identifying comorbidities that either improve or potentially diminish the individual 's capacity to perform effective self-care behaviors is essential to enhance clinical outcomes .
One such framework conceptualizes comorbidities as concordant or discordant with diabetes pathophysiological pathways and care goals .
Objective : The purpose of this systematic review was to examine the role of diabetes-concordant and discordant chronic conditions on the performance of self-care behaviors in adults with T2D .
Symptoms of depression prospectively predict poorer self-care in patients with Type 2 diabetes.
AIMS To examine prospect ively the association of depression symptoms with subsequent self-care and medication adherence in patients with Type 2 diabetes mellitus . METHODS Two hundred and eight primary care patients with Type 2 diabetes completed the Harvard Department of Psychiatry/National Depression Screening Day Scale ( H AND S ) and the Summary of Diabetes Self-Care Activities ( SDSCA )  at baseline and at follow-up , an average of 9 months later . They also self-reported  medication adherence at baseline and at a follow-up . RESULTS Baseline H AND S scores ranged from 0 to 27 , with a mean score of 5.15 + /- 4.99 . In separate linear regression models that adjusted for baseline self-care , patients with higher levels of depressive symptoms at baseline reported significantly lower adherence to general diet recommendations and specific recommendations for consumption of fruits and vegetables and spacing of carbohydrates ; less exercise ;  and poorer foot care at follow-up ( beta ranging from -0.12 to -0.23 ; P < 0.05 ) . Similarly , each one-point increase in baseline H AND S score was associated with a 1.08-fold increase in the odds of non-adherence to prescribed medication at follow-up ( 95 % confidence interval 1.001 , 1.158 , P = 0.047 ) . Increases in depression scores over time also predicted poorer adherence to aspects of diet and exercise . CONCLUSIONS Depressive symptoms predict subsequent non-adherence to important aspects of self-care in patients with Type 2 diabetes , even after controlling for baseline self-care . Although the relationship between symptoms of depression and poorer diabetes self-care is consistent , it is not large , and interventions may need to address depression and self-care skills simultaneously in order to maximize effects on diabetes outcomes
