Cardiovascular disease risk factor intervention in low-income women: the North Carolina WISEWOMAN project

OBJECTIVES: The North Carolina WISEWOMAN project was initiated to evaluate the feasibility of expanding an existing cancer screening program to include a cardiovascular disease (CVD) screening and intervention program among low-income women. METHODS: Seventeen North Carolina county health departments were designated as minimum intervention (MI), and 14 as enhanced intervention (EI). The EI included three specially constructed counseling sessions spanning 6 months using a structured assessment and intervention program tailored to lower income women. RESULTS: Of the 2,148 women screened, 40% had elevated total cholesterol (> or = 240 mg/dL), 39% had low high-density lipoprotein cholesterol (HDL-C) levels (< 45 mg/dL), and 63% were hypertensive (systolic blood pressure 140 and/or diastolic blood pressure > or = 90 mm Hg or on hypertensive medication). The majority of women (86%) had at least one of these three risk factors. Seventy-six percent were either overweight or obese. After 6 months of follow-up in the EI health departments, changes in total cholesterol levels, HDL-C levels, diastolic blood pressure, and BMI were observed (-5.8 mg/dL, -0.9 mg/dL, -1.7 mm Hg, and -0.3 kg/m(2), respectively), but were not significantly different from MI health departments. A dietary score that summarized fat and cholesterol intake improved by 2.1 units in the EI group, compared with essentially no change in the MI group. CONCLUSIONS: Expanding existing cancer screening programs to include CVD intervention was feasible and may be an effective means for promoting healthful dietary practices among low-income women.
