This study provides data on differences between respondents and nonrespondents by gender and ethnicity in a multicenter community-based study that is rarely collected and that may be useful for estimating bias in prevalence estimates in other studies.
Demographic, general health, and cardiovascular risk factors were examined in black and white respondents and nonrespondents to the Atherosclerosis Risk in Communities (ARIC) Study, a prospective study investigating cardiovascular risk factors in approximately 16,000 adults that was initiated in 1986 in four U.S. communities.
In one of the communities (Jackson, MS) black participants were recruited exclusively ; in another (Forsyth County, NC) 12% of the eligible sample were black, whereas the samples in Washington County, MD and the northwestern suburbs of Minneapolis, MN were almost all white.
Demographic and health characteristics were collected during a home interview.
Subjects who subsequently agreed to complete a clinical examination were defined as respondents, while eligible participants who only took part in the home interview were considered to be nonrespondents.
Approxmately 75% of age-eligible individals (45-64 years) in each community completed the home interview.
In three of the communities 86-88% of those who took part in the home interview also completed the clinic examination, whereas only 63% did so in Jackson. (...)
