Health care users residing on the Mexican border. What factors determine choice of the U.S. or Mexican health system?

Using multivariate analytic techniques, this article examines the factors influencing choice of the Mexican or U.S. health care system by service users residing on the Mexican border. Data were obtained from a 1987 binational health survey of 660 households, conducted in Tijuana. The sample consisted of 1,162 household members who reported having used health services in the U.S. and/or Mexico in the 6 months prior to the interview. The findings indicate that out of all the health care users in a 6-month interval, 7% sought services in the United States and 93% sought services only in Mexico. A weighted logistic regression on entry into care shows that, after adjusting for all the other variables in the model, U.S. insurance coverage, transportation, older age, and male gender were the most significant predictors. U.S. insurance, the strongest predictor of access, was associated with a labor history and legal residence across the border. Among U.S. users, the average number of visits was 2.6 (SD = 2.7). Sex, transportation, and socioeconomic status were significant predictors of volume of visits, in a weighted least squares regression analysis. The probability of more contacts among women is linked to their reproductive needs. An increasing use of U.S. health care is expected as a consequence of the new immigration law.
