Item Recruiting Diverse Patients to a Breast Cancer Risk Communication Trial—Waiting Rooms Can Improve Access(2007) Bodurtha, Joann N.; Quillin, John M.; Tracy, Kelly A.; Borzelleca, Joseph; McClish, Donna; Wilson, Diane Baer; Jones, Resa M.; Quillin, Julie; Bowen, DeborahLow participation among underserved populations in health research constrains progress in public health practices. From 2003 to 2005, Women’s Health Clinic patients at the VCU Health System were recruited to a trial investigating breast cancer risk communication. In secondary analyses, we examined dimensions of the recruitment of these diverse women. The sample characteristics (age, insurance, race and previous mammograms) were compared to the overall clinic. Of recruitment attempts for eligible women, 45% consented; of those who declined, the top cited reasons were lack of time (40%) and lack of interest (18%). Of 899 participants, 35% qualified for the indigent care program, compared to 31% of the overall clinic (P<0.001). Forty-five percent of participants were African American, compared to 54% of overall clinic patients (P<0.001). Participants were younger (50 vs. 53 years, P<0.001) than the overall clinic population. Nonrepresentative enrollment of patients in clinical trials is common and could lead to suboptimal applicability of findings. Although there were statistically significant race and age differences between the study sample and the overall population, we demonstrate that waiting room recruitment can engage diverse women in a clinical trial and cancer risk communication.Item Effects of Exercise on Total and Intra-abdominal Body Fat in Postmenopausal Women(2003) Irwin, Melinda L.; Yasui, Yutaka; Ulrich, Cornelia M.; Bowen, Deborah; Rudolph, Rebecca E.; Schwartz, Robert S.; Yukawa, Michi; Aiello, Erin; Potter, John D.; McTiernan, AnneContext The increasing prevalence of obesity is a major public health concern. Physical activity may promote weight and body fat loss. Objective To examine the effects of exercise on total and intra-abdominal body fat overall and by level of exercise. Design Randomized controlled trial conducted from 1997 to 2001. Setting and Participants A total of 173 sedentary, overweight (body mass index 24.0 and >33% body fat), postmenopausal women aged 50 to 75 years who were living in the Seattle, Wash, area. Intervention Participants were randomly assigned to an intervention consisting of exercise facility and home-based moderate-intensity exercise (n = 87) or a stretching control group (n = 86). Main Outcome Measure Changes in body weight and waist and hip circumferences at 3 and 12 months; total body, intra-abdominal, and subcutaneous abdominal fat at 12 months. Results Twelve-month data were available for 168 women. Women in the exercise group participated in moderate-intensity sports/recreational activity for a mean (SD) of 3.5 (1.2) d/wk for 176 (91) min/wk. Walking was the most frequently reported activity. Exercisers showed statistically significant differences from controls in baseline to 12-month changes in body weight (–1.4 kg; 95% confidence interval [CI], –2.5 to –0.3 kg), total body fat (–1.0%; 95% CI, –1.6% to –0.4%), intra-abdominal fat (–8.6 g/cm2; 95% CI, –17.8 to 0.9 g/cm2), and subcutaneous abdominal fat (–28.8 g/cm2; 95% CI, –47.5 to –10.0 g/cm2). A significant dose response for greater body fat loss was observed with increasing duration of exercise. Conclusions Regular exercise such as brisk walking results in reduced body weight and body fat among overweight and obese postmenopausal women.
