OBJECTIVES: Few studies have focused on access to care for women through utilization of a mobile mammography unit.  Bonnie’s Bus Mammography Mobile Program (BBMMP) was created to provide mammograms to women in rural areas throughout West Virginia (WV) and surrounding areas.  Based on a 3-year analysis of the data, 80.4% of its clientele had a BMI of 30 or above as compared to 64.9% for all WV women age 40 and above.  Thus, the objectives of the study were to: 1) to describe the demographics and comorbidities of women who utilized BBMP, and 2) to determine the association between BMI and personal health and screening history, preventive care, and wellness behaviors.  METHODS:  Three years BBMP surveillance data collected from 1099 women age 40 and above were analyzed.  BMI by personal health and screening history, preventive care, wellness behaviors, and demographics were analyzed using descriptive statistics, chi-square tests, and a linear regression model.  RESULTS: Women were mostly married (60.4%), had health insurance (53.2%), were employed (46.5%), and had an annual income between $10,000-25,000 (40.9%).  Major comorbidities were hypertension (49%) and high cholesterol (43.9%).  Increasing BMI was associated with greater likelihood of thyroid disease, hypertension, diabetes, high cholesterol, allergies, hormone replacement therapy use, activity limitations, perceived weight problem, lower exercise, inability to get medications due to cost, lower doctor visits, and being single. Those with lower BMI were less likely to smoke or drink alcohol. The regression model was significant (F=13.729, p<0.001, R2 = 0.412) and indicated that women who engaged in preventive care behaviors were less likely to be obese than those who did not.  CONCLUSIONS:  The BBMMP attracted women who were disproportionately obese and had multiple co-morbidities, thus providing a great opportunity for targeted interventions related to improving preventive care, screening, and self-care behaviors.
