Note: All models are adjusted for sex, age, partnership status, education, income, physical activity, fast food consumption, current cigarette smoker, and depressive symptoms. Systolic and diastolic blood pressure were adjusted for antihypertensives, and triglycerides and HDL-C for lipid lowering medications. Significance: *P < 0.05. **P < 0.01. ***P < 0.001.
