Recruitment Strategies in the Women’s Health Trial

The Womens Health Trial:Feasibility Study in Minority Populations (WHT:FSMP) examined the feasibility of recruiting postmenopausal women from a broad range of racial and socioeconomic backgrounds into a primary prevention trial requiring marked reductions in dietary fat. Postmenopausal women aged 50-79 yr who had no history of cardiovascular disease or cancer and who consumed 36% or more total energy from fat qualified to participate. We randomized the women into dietary intervention (60%) or control (40%) groups; we aimed to randomize 750 women in 18 months in each of the three clinical centers. All centers achieved goals for randomization based on ethnicity, and two centers exceeded overall recruitment goals. The greatest source of randomized participants was mass mailing, followed by items in the media, referrals, and community outreach. Recruitment yields were generally similar for the ethnic groups but lower for less-educated participants. The experience of WHT:FSMP indicates that postmenopausal women from the African-American, Hispanic, and non-Hispanic white communities can be recruited into dietary intervention studies for the prevention of disease.

The Women's Health Trial Feasibility Study in Minority Populations: Design and baseline descriptions

The Womens Health Trial: Feasibility Study in Minority Populations (WHT:FSMP), a randomized trial of 2208 women, was conducted to investigate three questions. First, can women from minority and low-socioeconomic-status populations be recruited in numbers sufficient to evaluate a dietary intervention designed to lower fat intake. Second, the efficacy of a low fat, increased fruit/vegetable/ grain product intervention for reducing fat consumption. Third, will participation in the intervention lower plasma cholesterol and estradiol levels relative to the controls. The baseline results showed that an adequate number of minority and low SES women could be recruited to test the study hypotheses. A diverse study population of postmenopausal women consuming a high fat diet was recruited: 28% of participants were Black, 16% were Hispanic, 11% had less than a high school level of education, and 15.5% had household incomes of <

The purpose of this study is to determine the impact of moderate intensity exercise on acute post-exercise energy intake (EI) in normal and overweight females. Twelve normal weight (BMI<25), and 12 over weight (BMI>25) inactive women (mean age 35+/-8) participated in a 2-day experimental study. On the exercise day, participants were asked to walk on a treadmill at 60% maximum heart rate for 1h. After the exercise, participants selected and ate food at a university cafeteria. Post-exercise EI was compared to a non-exercise day. A single mixed model repeated 2 x 2 ANOVA was used to determine the impact of exercise on post-exercise EI. The overweight women consumed significantly more (p<0.02) than the normal weight women on both experimental days and there was a significant (p<0.03) difference in fat intake. The higher post -exercise EI of the overweight group may have been due to the energy needs associated with a higher BMI but it is also possible that cognitive factors, food availability and environment may influence post-exercise EI.

Eating Disorder Risk and Body Dissatisfaction Based on Muscularity and Body Fat in Male University Students

OBJECTIVE To evaluate weight concerns, weight-loss practices (including smoking) in an ethnically diverse group of university students (58% Hispanic). METHODS Students (n=1,852) completed a survey addressing lifestyle behaviors and weight-control practices. RESULTS A greater percentage of females than males practiced weight-loss behaviors. More Hispanic and non-Hispanic white students reported dieting, exercising, and using weight loss pills to lose weight. Only 4 of the females reported their primary reason for smoking was to control their weight. CONCLUSION Gender as well as ethnicity was a dominant factor influencing weight-loss behaviors/concerns of these young adults.

The impact of dietary restraint and moderate-intensity exercise on post-exercise energy intake in sedentary males.

Recruiting participants for large prevention trials is time consuming and costly. In order to test various recruitment techniques, we conducted two studies of response rates to recruitment mailings for the Womens Health Trial. The potential participants, 50- to 79-year-old women, were requested to return an enclosed postcard to learn more about the trial. In the first study, we sent at random either a short or a long message to a group of University of Miami personnel (N = 862) and a Dade County cohort (N = 2964). More university women responded to the short message than to the long message (22.4% vs 16.4%, p = 0.024). Similarly, more of the Dade County cohort replied to the short message than to the long one (12.1% vs 9.6%, p = 0.027). The long message listed details of the intervention (e.g., modifying recipes) that some women may have used to decide they were not interested in participating. In the second study, we examined response rates to two different ways of addressing the mailing, i.e., handwritten envelopes and machine-printed labels; we also evaluated three methods for delivering the short message: (1) formal invitation, (2) business letter with an inside name and address of the recipient, and (3) business letter without the recipients name and address. Response rates were similar between the methods of addressing envelopes and among the three vehicles for the message, suggesting that the least costly method of mailing should be used.

Computer-Assisted Education for Dietetics Students: A Review of Literature and Selected Software

Abstract Objective: To investigate the relationship between risk of eating disorders, body dissatisfaction, and perceptual attractiveness in male university students. Participants: Research was conducted January–April 2012 and involved 339 male and 441 female students. Methods: Eating disorder risk was assessed with the Eating Attitudes Test (EAT) and body dissatisfaction and perceptual attractiveness determined with the Bodybuilder Image Grid (BIG). Results: There was a positive correlation (r = .16, p < .01) between the EAT and fat dissatisfaction and a negative correlation (r = −.14, p < .05) for muscle dissatisfaction, 28% of the males had an EAT score indicating that they were at risk for an eating disorder. Males chose a significantly more muscular and leaner body type than what females chose to be attractive. Conclusion: College-aged males may be at risk for eating disorders based on distortions in their perceived ideal body image, both for fat and muscle.

Dietary restraint influences accuracies in estimating energy expenditure and energy intake among physically inactive males.

Exercise is often used for successful weight management, particularly by males. However, exercise may have the potential to promote counter-regulatory eating, because of certain cognitive and psychological factors. The purpose of this study was to investigate the unknown role of dietary restraint, BMI, and dieting status on acute and 12-hour post-exercise energy intake (PE-EI) in sedentary males following moderate-intensity exercise. The study consisted of two experimental conditions, exercise and rest, in a counterbalanced-crossover design on two days. Exercise consisted of walking on a treadmill for 60 min. Acute and 12-hour PE-EI were compared on exercise and rest days. Eighty males, mean age 30+/-8 years, participated in the study and were categorized by dietary restraint level, BMI, and dieting status. The main effects of condition and group, and the interaction were not significant for acute or 12-hour PE-EI, suggesting that a single bout of moderate-intensity exercise did not influence PE-EI in sedentary males in reference to dietary restraint, BMI, and dieting status. Therefore, moderate-intensity exercise as a prescription for weight loss does not appear to promote counter-regulatory eating in sedentary males.
