Latino patients aged 鈮?#xA0;50 with 鈮?#xA0;1 visit during the preceding year (N = 1314) were sampled from three community clinics and a multi-specialty medical group. Patients were randomly assigned to receive or not receive a pamphlet that contained information on research participation in the initial mailing for the telephone survey study. Survey participation rates were compared between the pamphlet and no pamphlet groups.
In a multivariate model, women (OR = 1.4; 95%CI 1.1, 1.8), and those with public insurance (vs. no insurance; OR = 1.7; 95%CI 1.1, 2.5) were more likely to participate, while those age 65 + (vs. age 50-54; OR = 0.6; 95%CI 0.4, 0.8) were less likely to participate; there was no significant difference by pamphlet group (OR = 0.8; 95%CI 0.7, 1.1). Nesting of the randomized trial of the recruitment pamphlet within the funded study required minimal additional resources.
Recruitment methods that are more intensive than a pamphlet may be needed to enhance survey participation rates among older Latinos. Nesting recruitment trials within funded studies is a promising and efficient approach for testing recruitment strategies.
