Use of preventive care services among Latino subgroups

Area of Science:

• Health Services Research
• Health Disparities
• Preventive Medicine

Background:

• Existing research shows disparities in preventive care access between Latinos and non-Latino whites.
• Previous studies often group diverse Latino subgroups, masking variations in care utilization.
• There is a lack of data on preventive care consistency across major Latino subgroups.

Purpose of the Study:

• To analyze determinants of adult preventive care receipt among major U.S. Latino subgroups and non-Latino whites.
• To compare disparities in three preventive care bundles.
• To examine the role of observed and unobserved factors in preventive care differences.

Main Methods:

• Merged data from the Medical Expenditure Panel Survey and National Health Interview Survey (2000-2006).
• Analyzed a sample of 28,781 Latinos and 78,979 non-Latino whites.
• Utilized multivariate models and decomposition techniques to identify disparities and their causes.

Main Results:

• Latinos of Mexican and Central/South American origin received guideline-recommended preventive care less often than other groups.
• Disparities were most pronounced for cost-effective services like smoking cessation, colorectal cancer screening, and influenza vaccination.
• Lack of health insurance and a usual source of care were key factors explaining these disparities.

Conclusions:

• Expanding health insurance coverage and integrating Latinos into primary care can significantly reduce preventive care disparities.
• Preventive care initiatives should focus on improving access to cost-effective services for Mexican and Central/South American Latinos.
