Preventive services for adults: how have differences across subgroups changed over the past decade?

Area of Science:

• Health Services Research
• Public Health
• Health Disparities

Background:

• Existing research highlights cross-sectional disparities in adult preventive care utilization across various population subgroups.
• However, limited data exists on the temporal trends of these differences over time.

Purpose of the Study:

• To analyze changes in the utilization of preventive services over time.
• To examine these changes across subgroups defined by poverty status, race/ethnicity, insurance coverage, Census region, and urbanicity.

Main Methods:

• Utilized data from the Medical Expenditure Panel Survey (1996-2008).
• Examined five key preventive services: general checkups, blood pressure screening, blood cholesterol screening, Pap smears, and mammograms.
• Employed multivariate logistic regression to calculate adjusted utilization rates for different subgroups across three time periods (1996/1998, 2002/2003, 2007/2008).

Main Results:

• Persistent disparities in preventive service utilization across subgroups were observed between 1996/1998 and 2007/2008, with few instances of narrowing or widening gaps.
• Significant utilization gaps were most pronounced between adults with and without health insurance coverage.
• While most gaps remained stable, a notable narrowing was observed in blood cholesterol screening between the uninsured and privately insured populations. Regional differences persisted or increased.

Conclusions:

• Persistent disparities in preventive care access and utilization pose a significant challenge for the Affordable Care Act.
• Addressing these ingrained inequities is crucial for improving population health outcomes.
• Future health reforms must prioritize strategies to reduce these persistent gaps in preventive services.
