p(HT)=p values for HT group across the entire sample after adjusting for natural vs. surgical menopause and age. p(MP)=p value for type of menopause from the same model, after adjusting for HT group and age.
BMI=body mass index, DASI=Duke Activity Status Inventory, a measure of functional capacity and physical activity habits, Hx=history of, ATP III Risk=National Cholesterol Education Program, Adult Treatment Panel III Global Coronary Heart Disease Risk Score (see Methods), Chronic Disease includes diabetes, COPD, renal disease, autoimmune disease, anorexia, or >25 drinks/week.
Non-significant variables included: marital status, Hx hypertension, Hx dyslipidemia, Hx smoking, Family Hx CAD, systolic and diastolic blood pressure, waist circumference, waist/hip ratio, prior CAD, lipid lowering therapy, antihypertensive therapy, anxiolytics, ACE inhibitors and nitrates. There were significant menopause type * HT group interaction terms for diabetes (p=0.01), Vitamins C, E, A (p=0.04), other chronic disease (p=0.01), age at menopause (p<0.0001), years since menopause (p=0.04). All other interactions were non-significant.
