Abstract
OBJECTIVES: Lack of health insurance and a regular source of medical care are barriers affecting use of health services by Mexican Americans. We studied perinatal and infant health service use by Mexican-American women and non-Hispanic white women and their infants enrolled in Arizona's Medicaid program and explored characteristics associated with use of health services. DESIGN: A descriptive comparative study that used data collected from office records, birth certificates, and household interviews. SETTING: Participants resided in the state's most populous county and were enrolled in the Arizona Health Care Cost Containment System, a health maintenance organization-oriented Medicaid demonstration project. SUBJECTS: Random sample of 308 Mexican-American mother-infant dyads and 312 non-Hispanic white mother-infant dyads. The women were enrolled before the sixth month of pregnancy and for 60 days post partum; their infants were continuously enrolled throughout their first year. OUTCOME MEASURES: Timing and number of prenatal visits and a modified Kessner Index, postpartum visits, number and purpose of office visits during the infants' first year, and immunizations received. RESULTS: Mexican Americans averaged fewer prenatal visits than non-Hispanic whites (8.6 vs 10.2 visits) and were less likely to have "adequate" care (41.1% vs 52.8%). Both groups of mothers are well below the 68% of women nationally who receive adequate prenatal care. Controlling for important socioeconomic status and cultural characteristics, ethnicity had a strong independent effect on the number of prenatal visits and adequacy of prenatal care. Mexican-American infants made fewer visits (8.2 vs 9.8) and completed fewer age-appropriate immunizations than non-Hispanic whites. CONCLUSIONS: Health insurance and a regular source of care are insufficient conditions for ensuring adequate use of maternal and child health services by Mexican-American Medicaid enrollees. Factors associated with their less frequent use of these preventive health services include higher numbers of children, transportation problems, and less assistance from their support system.
