    Abstract:
    BACKGROUND: This study assessed the validity of several self-reported cardiovascular risk factors among low-income women aged 40-64 years in West Virginia. METHODS: A cross-sectional survey was conducted of 733 women participating in the Well Integrated Screening and Evaluation for Women Across the Nation (WISEWOMAN) project in West Virginia to examine agreement between self-report and clinical screenings in the prevalence of risk factors related to coronary heart disease (CHD). Women participating in the study were interviewed face-to-face before administration of clinical screenings that assessed height, weight, Quetelet's index, high blood pressure (systolic > or =140 mm Hg or diastolic > or =90 mm Hg), and elevated total cholesterol concentrations (> or =200 mg/dL and > or =240 mg/dL). RESULTS: The overall results showed high sensitivity and specificity for each of the risk factors examined; for overweight/obesity, the sensitivity was 96% and specificity was 93%; for cholesterol > or =240 mg/dL, sensitivity was 85% and specificity was 67%; for hypertension, sensitivity was 77% and specificity was 86%. Using a threshold value of > or =240 mg/dL for hypercholesterolemia led to higher sensitivity but a lower specificity than for a value of > or =200 mg/dL. CONCLUSIONS: This study found that among low-income women at higher risk for cardiovascular disease (CVD), self-reported values for high body mass index (BMI), hypercholesterolemia, and hypertension were well correlated with clinical measures, as indicated by high sensitivity values. Thus, self-reported values can be used for surveillance, targeted screenings, and health promotion activities, including lifestyle changes.
