Differences In Response Patterns by Socio-Demographic Characteristics In Cancer Prevention Study-3

Year: 2025
Type: article
Abstract: INTRODUCTON: Longitudinal prospective cohort studies are essential to understanding disease risk over time. Participant retention is critical to maintaining scientific validity, but participant attrition is a challenge and may vary by factors such as age, race/ethnicity, or sex. We examined response patterns over time in a large U.S. prospective cohort by various demographic factors. AIM: The aim of this analysis was to examine the response patterns of CPS-3 participants across the three survey cycles, with a focus on how four socio demographic characteristics – gender, race, age, and education at enrollment - affect engagement and survey completion. METHODS: From 2006-2013, ~250,000 adults were enrolled in the American Cancer Society’s Cancer Prevention Study-3 (CPS-3) and completed a baseline survey. In 2015 and every three years thereafter, participants received follow-up surveys to update exposure and health information. The response rate was calculated by dividing the number of completed surveys received by the total number of individuals who were alive at the start of the cycle and received a survey mailing during that period. In 2015 and every three years thereafter, participants received follow-up surveys to update exposure and health information. The response rate is calculated using the formula: Response = (usable returns) / (alive at the beginning of the cycle and mailed to during the cycle).We examined response patterns by race (white, Black, Hispanic, Asian, other), baseline age (<35, 35-44, 45-54, 55-64, and 65+ years), sex (male, female), and education (
