Abstract

Aims To examine prospectively 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 (HANDS) 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 HANDS 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 (β ranging from −0.12 to −0.23; P < 0.05). Similarly, each one‐point increase in baseline HANDS 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.

  • Longitudinal data support the directionality of the relationship and show that baseline symptoms of depression and increases in depressive symptoms over time are each significantly associated with worse diabetes self-care 9 months later, even when baseline levels of self-care are controlled.

    “we have recently published longitudinal data that support the directionality of this relationship and show that baseline symptoms of depression and increases in depressive symptoms over time are each significantly associated with worse diabetes self-care 9 months later, even when baseline levels of self-care are controlled [8].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
