Abstract

OBJECTIVE: : Associations between income disparity and utilization of cardiovascular disease (CVD) preventive care services, such as receipt of lifestyle advice and screening for CVD risk factors in populations with and without CVD, are not well understood. The purpose of this study was to evaluate associations between income and utilization of CVD-preventive services among U.S. adults. METHODS: : We included adults ≥18 years with and without CVD from the 2006 to 2015 Medical Expenditure Panel Survey. We categorized participants as high-income (>400% of federal poverty level [FPL]), middle income (200-400% of FPL), low-income (125-200% of FPL) and very low (VL)-income (<125% of FPL). We used logistic regression to compare the likelihood of receiving CVD-preventive services by income strata, adjusting for sociodemographic factors and comorbidities. RESULTS: : The study included 185,081 participants (representing 194.6 million U.S. adults) without CVD, and 32,862 participants (representing 37 million U.S. adults) with CVD. VL-income adults without CVD were less likely than high-income adults to have blood pressure measured within past 2 years [odds ratio [OR] 0.41 (95% confidence interval [CI] 0.37-0.45)] or cholesterol levels checked within past 5 years [0.36 (0.33-0.38)] or receive counseling about diet modifications [0.77 (0.74-0.81)], exercise [0.81 (0.77-0.85)], or smoking cessation [0.71 (0.63-0.79)] within past year. VL-income adults with CVD were also less likely to have blood pressure [0.32 (0.22-0.46)] or cholesterol [0.33 (0.26-0.42)] checked and receive counseling about exercise [0.84 (0.76-0.93)] or smoking cessation [0.78 (0.61-0.99)]. Additional subgroup analyses restricted to participants who had seen a healthcare provider within the preceding 12 months, as well as secondary analyses stratified by sex, race and ethnicity, showed similar disparities between high-income and VL-income participants. CONCLUSIONS: : VL-income adults were less likely to be screened for CVD risk factors or receive CVD-prevention counseling than high-income adults, regardless of CVD status. More work must be done to reduce disparities in access to and utilization of CVD-preventive services among adults in different income groups.

TL;DR

In a nationally representative MEPS sample from 2006–2015, low- and very-low-income U.S. adults were significantly less likely than high-income adults to receive cardiovascular preventive services, regardless of CVD status. Disparities largely persisted after adjustment and among those who had seen a provider in the past year, though some subgroup estimates were no longer statistically significant.

Key findings

  • Among participants without CVD, adjusted odds for low- and very-low-income vs high-income adults were lower for smoking cessation counseling [OR 0.70 (95% CI 0.62–0.79) and OR 0.71 (0.63–0.79)], BP checked within 2 years [OR 0.45 (0.42–0.49) and OR 0.41 (0.37–0.45)], exercise counseling [OR 0.79 (0.75–0.84) and OR 0.81 (0.77–0.85)], dietary counseling [OR 0.77 (0.73–0.81) and OR 0.77 (0.74–0.81)], and cholesterol checked within 5 years [OR 0.42 (0.39–0.45) and OR 0.36 (0.33–0.38)].
  • Among participants with CVD, adjusted odds for low- and very-low-income vs high-income adults were lower for smoking cessation counseling [OR 0.64 (0.48–0.86) and OR 0.78 (0.61–0.99)], BP checked within 2 years [OR 0.34 (0.24–0.49) and OR 0.32 (0.22–0.46)], exercise counseling [OR 0.79 (0.71–0.87) and OR 0.84 (0.76–0.93)], and cholesterol checked within 5 years [OR 0.34 (0.28–0.42) and OR 0.33 (0.26–0.42)]; dietary counseling was lower for low-income [OR 0.84 (0.76–0.93)] but not very-low-income [OR 0.95 (0.86–1.04)] participants.
  • In the subgroup restricted to participants who visited a provider within the past year, disparities mostly persisted; for example, without CVD, BP check ORs were 0.65 (0.56–0.75) and 0.65 (0.56–0.77), and cholesterol check ORs were 0.57 (0.52–0.62) and 0.55 (0.50–0.61) for low- and very-low-income adults. With CVD, exercise counseling ORs were 0.70 (0.62–0.79) and 0.67 (0.60–0.74), and cholesterol check ORs were 0.54 (0.40–0.73) and 0.44 (0.31–0.61).

Methods

  • Retrospective observational study using Medical Expenditure Panel Survey (MEPS) data from 2006–2015; after exclusions, the sample included 185,081 participants without CVD (representing 194 million U.S. adults) and 32,862 with CVD (representing 37 million U.S. adults).
  • Income was categorized as high (>400% federal poverty level [FPL]), middle (200–400% FPL), low (125–200% FPL), or very low (<125% FPL). Outcomes were self-reported smoking cessation counseling, BP checked within 2 years, exercise counseling, dietary counseling, and cholesterol checked within 5 years.
  • Analyses used χ² tests and multivariable logistic regression with high-income as reference, adjusted for age, race/ethnicity, sex, region, health insurance, educational status, and Charlson Comorbidity Index; subgroup analyses were restricted to those who visited a provider within the prior 12 months, with secondary analyses stratified by sex, race, and ethnicity.

Limitations

  • Stated: MEPS relies on self-report, so recall bias may lead to underestimating CVD history or misreporting service use; income is intertwined with race/ethnicity, education, and insurance; observational design cannot establish causality and residual confounding is possible; low-income participants were more likely to be Black or Hispanic, uninsured, and less educated; very-low-income participants were younger; regional residual confounding may remain due to lack of granular geographic data; and visit regularity could not be fully adjusted for despite subgroup analysis.
  • Evident: the cross-sectional design cannot establish temporal ordering between income and receipt of preventive services, and the study relies on survey responses rather than clinical verification of services.

    “Other studies have shown the disparity in utilization of preventive care services supported by the U.S. Preventive Services Task Force such as BP and cholesterol screening based on insurance status, though not necessarily based on income [27,28].”

    Modifiable CVD risk factors are associated with worse cardiovascular outcomes such as myocardial infarction, stroke, heart failure and death.

    The ICD-9-CM codes used to identify CVD accurately identify individuals with CVD.

    “Individuals with CVD were identified by self-report or International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes for the diagnoses of coronary artery disease (ICD-9: 410, 413, and 414), stroke (ICD-9: 433–437), heart failure (ICD-9: 428), cardiac dysrhythmia (ICD-9: 427) or peripheral artery disease (ICD-9: 440, 443, 447).”
  • The paper relies on this without support.

    Lower utilization of CVD preventive services causally leads to worse cardiovascular outcomes (uncontrolled risk factors and incident or worsening CVD).

    “This places socioeconomically disadvantaged populations at greater risk of having uncontrolled CVD risk factors and subsequently developing new or worsening CVD.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-14.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-14.

Cited sources are checked by gpt-6-sol.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
