Authors evaluated the variation among and representativeness of controls identified using multiple methods for a population-based case-control study of breast cancer among Asian Americans, Native Hawaiians and Pacific Islanders (AANHPIs) in the San Francisco Bay Area using a unique combination of targeted recruitment strategies, including address-based sampling, community-based methods, and Internet-based and media-based approaches for recruiting controls, frequency matched on age and ethnicity to a population-based sample of cases.
Authors compared distribution of sociodemographic characteristics and cancer risk factors between recruitment sources. To ensure that the controls recruited were representative of the underlying at-risk population, the authors compared characteristics of the controls, by ethnicity and in aggregate, to data from the 2011-2012 California Health Interview Survey (CHIS), and adjusted the relative mix of recruitment strategies throughout the study as needed to achieve representativeness.
