Enrollment Challenges: Recruiting Men to Weight Loss Interventions.

Abstract

Obese men are at an increased risk of chronic disease and are far less likely than women to attempt weight loss. There is a need to successfully recruit men to weight loss clinical trials. Overweight and obese men were recruited to a 6-month, randomized, controlled weight loss trial. Initial recruitment efforts were aimed at men in the workplace with less than or equal to 2 years of college education. After unsatisfactory interest from men and businesses alike, recruitment strategy shifted to enroll men outside the workplace with any educational background. Recruitment methods included word of mouth, email and website advertisements, printed posters in local businesses and doctors’ offices, Facebook ads, and a 1-week newspaper ad campaign. Initial interest and enrollment was negligible with only 35 men enrolled in the first 7 months. The launch of a 1-week newspaper advertisement was the most useful recruitment technique and 102 overweight/obese men were successfully enrolled. Study retention remained high throughout the Gutbusters program, indicating targeted, effective recruitment, and not weight loss interest, may be the largest barrier to trial participation for overweight and obese men.
