Abstract
Objectives: To examine sex-specific associations between depressive symptoms and cardiovascular risk factors in older men and women.
Method: One hundred and thirty-one healthy, community-dwelling older adults [mean age = 66(6.59), 63% male] completed the Beck depression inventory, and engaged in assessment of systolic and diastolic blood pressure, body mass index (BMI), waist circumference (WC), fasting total, low- and high-density lipoprotein cholesterol (TC, LDL-C, and HDL-C), triglycerides, glucose, insulin, and maximal aerobic capacity (Vo2max). Sex-stratified hierarchical regression analyses examined the association between depressive symptoms and each risk factor adjusting for age, education, and BMI (select models).
Results: Significant associations were found between higher levels of depressive symptoms and greater BMI, WC, insulin, LDL-C, and lower Vo2max in women only (p < 0.05). The insulin association was partially mediated by BMI.
Conclusion: In healthy older women, but not men, higher levels of depressive symptoms were associated with greater CVD risk factors. Depressive symptoms may confer biobehavioral risk for cardiovascular and metabolic diseases in older women in part via their association with pertinent biomedical risk factors.
