Differential ethnic misclassification of Hispanics: Northern California.

Abstract: Hispanic ethnicity is used as a category for calculating population-based rates in epidemiology This study explores potential determinants of ethnic misclassification in a weighted sample of 1154 persons in the San Francisco-Oakland cancer registry where ethnic classification is based on surname or medical record report rather than self-identification Logistic regression models were created for predictive value positive and predictive value negative Persons who were classified as Hispanic were most likely to identify themselves as Hispanic if they were Spanish speakers had Hispanic maiden names or surnames and were not recent immigrants who spoke another language Persons who were classified as non-Hispanic were most likely to identify themselves as non-Hispanic if they had government insurance were younger were not Spanish speakers and did not have Hispanic maiden or mothers maiden names The authors conclude that socioeconomic and demographic factors may influence Hispanic classification and lead to biases in the calculation of rates (authors)
