Pilot Study Description
The goal of Dr. José Escarce's CHIME pilot study was to assess the existence and direction of bias in cross-sectional health comparisons of immigrant and U.S.-born Latinos, using data from the National Health Interview Surveys (NHIS) for 1989-1991 and 1999-2001. The NHIS is an annual survey of a nationally representative sample of the non-institutionalized U.S. population and includes information on race, ethnicity, country of ancestry, socioeconomic characteristics, several indicators of health status, and, beginning in 1989, place of birth. By pooling the data from three surveys conducted 10 years ago and three recent surveys, Dr. Escarce planned to obtain sufficient sample sizes to compare the health of immigrants and U.S.-born Latinos surveyed around 1990 with the health of those surveyed around 2000, a span of about half a generation, while stratifying the analyses by country of ancestry. Dr. Escarce and his colleagues planned to perform descriptive analyses comparing age- and sex-adjusted health indicators for immigrants and U.S.-born Latinos in 1990 and 2000, as well as multivariate regression analyses that adjusted for education and other socioeconomic characteristics. Although lack of data on place of birth prior to 1989 prevented them from going back a full generation with the NHIS, going back half a generation was considered sufficient to detect quantitatively important bias in cross-sectional comparisons and determine its direction.
