Cardiovascular Disease Risk Factors, Depression Symptoms and Antidepressant Medicine Use in the Look AHEAD (Action for Health in Diabetes) Clinical Trial of Weight Loss in Diabetes
Aims/hypothesis - To determine the associations of baseline depression symptoms and use of antidepressant medicines (ADMs) with baseline cardiovascular disease (CVD) risk factors in Look AHEAD (Action for Health in Diabetes) trial participants.
Methods - Look AHEAD participants (n = 5,145; age 58.7 ± 6.8 years; BMI 35.8 ± 5.8 kg/m2) were assessed for CVD risk factors (elevated HbA1c or insulin use, elevated BP or antihypertensive use, elevated lipid levels or lipid-lowering medication, current smoking, BMI ≥30 kg/m2, lower peak exercise capacity assessed as metabolic equivalents [METs], and ankle–brachial index <0.9 or >1.3). Participants also completed the Beck Depression Inventory (BDI) and reported their use of ADMs.
Results - Of the participants, 14.7% had BDI scores ≥11, consistent with mild-moderate depression, and 16.5% took ADMs; 4.4% had both depression markers (i.e. elevated symptom scores and took ADMs). In logistic regression analyses of CVD risk (elevated risk factor or use of medication to control the risk factor), controlled for demographic factors, continuous BDI scores and ADM use were each independently associated with elevated BP (or medication), current smoking, BMI ≥30 kg/m2 and lower MET values. ADM use was also associated with elevated serum lipids or use of lipid-lowering medication.
Conclusions/interpretation - Among Look AHEAD participants, depression symptoms or ADM use on entry to the study were each independently associated with a wide range of CVD risk factors. Future research should assess the temporal dynamics of the relationships of depression symptoms and ADM use with CVD risk factors.
