Racial and ethnic differences in childhood asthma treatment in the United States.

ABSTRACT:

Objective

To examine racial-ethnic differences in asthma controller medication use among insured U.S. children.

Data sources

Linked nationally representative data from the Medical Expenditure Panel Survey (2005-2008), the 2000 Decennial Census, and the National Health Interview Survey (2004-2007).

Study design

The study quantifies the portion of racial-ethnic differences in children's controller use that are attributable to differences in need, enabling and predisposing characteristics.

Principal findings

Non-Hispanic black and Hispanic children were less likely to use controllers than non-Hispanic white children. Blinder-Oaxaca decomposition results indicated that observable characteristics explain less than 40 percent of the overall differential in controller use between non-Hispanic whites and non-Hispanic blacks. In contrast, observable characteristics explain more than two-thirds (71.3 percent) of the overall non-Hispanic white-Hispanic differential in controller use. For non-Hispanic blacks, a majority of the explained differential in controller use were attributed to enabling characteristics. For Hispanics, a significant portion of the explained differential in controller use was attributed to predisposing characteristics. In addition, a larger portion of the differential in controller use was explained by observable characteristics for publicly insured non-Hispanic black and Hispanic children.

Conclusions

The large observed differences in controller use highlight the continuing challenges of ensuring that all U.S. children have access to quality asthma care.

Project description:BackgroundRacial/ethnic disparities in the utilization of hematopoietic cell transplantation (HCT) have been reported for patients with hematologic malignancies, but population-based data are lacking for lymphoma patients. The objective of this study was to determine whether racial and ethnic disparities exist in the utilization of autologous HCT for lymphoma in the United States.MethodWe used Surveillance, Epidemiology, and End Results data linked to Medicare fee-for-service claims. We included Medicare beneficiaries aged 66+ years with Hodgkin or Non-Hodgkin lymphomas diagnosed between 2008 and 2015. The primary outcome was time-to-autologous HCT. We used Cox proportional hazards models to estimate racial/ethnic differences in utilization. Missing data were handled using multiple imputation with chained equations.ResultsWe included 40,605 individuals with lymphoma. A total of 452 autologous transplants were performed. In the unadjusted model, Non-Hispanic Black patients were 51% less likely to receive a transplant than Non-Hispanic White patients (95% CI, 0.26-0.96; p = 0.04). After adjusting for age at diagnosis and sex, Non-Hispanic Black patients were 61% less likely to receive a transplant (95% CI, 0.20-0.76; p = 0.01). However, observed differences attenuated and became non-significant after adjustment for socioeconomic factors (adjusted hazard ratio [aHR], 0.62; 95% CI, 0.32-1.21; p = 0.16) and disease-specific factors (aHR, 0.58; 95% CI, 0.30-1.12; p = 0.11), separately. In the fully adjusted model, we also did not observe a statistically significant association between Non-Hispanic Black race/ethnicity and receipt of transplant (aHR, 0.54; 95% CI, 0.28-1.05; p = 0.07).ConclusionIn this population-based cohort study of lymphoma patients, Non-Hispanic Black patients were less likely to receive autologous HCT compared to Non-Hispanic White patients, but this difference was partially explained by socioeconomic and disease-specific factors.

Project description:BackgroundSocial and psychosocial factors are associated with cardiovascular health (CVH). Our objective was to examine the contributions of individual-level social and psychosocial factors to racial and ethnic differences in population CVH in the NHANES (National Health and Nutrition Examination Surveys) 2011 to 2018, to inform strategies to mitigate CVH inequities.MethodsIn NHANES participants ages ≥20 years, Kitagawa-Blinder-Oaxaca decomposition estimated the statistical contribution of individual-level factors (education, income, food security, marital status, health insurance, place of birth, depression) to racial and ethnic differences in population mean CVH score (range, 0-14, accounting for diet, smoking, physical activity, body mass index, blood pressure, cholesterol, blood glucose) among Hispanic, non-Hispanic Asian, or non-Hispanic Black adults compared with non-Hispanic White adults.ResultsAmong 16 172 participants (representing 255 million US adults), 24% were Hispanic, 12% non-Hispanic Asian, 23% non-Hispanic Black, and 41% non-Hispanic White. Among men, mean (SE) CVH score was 7.45 (2.3) in Hispanic, 8.71 (2.2) in non-Hispanic Asian, 7.48 (2.4) in non-Hispanic Black, and 7.58 (2.3) in non-Hispanic White adults. In Kitagawa-Blinder-Oaxaca decomposition, education explained the largest component of CVH differences among men (if distribution of education were similar to non-Hispanic White participants, CVH score would be 0.36 [0.04] points higher in Hispanic, 0.24 [0.04] points lower in non-Hispanic Asian, and 0.23 [0.03] points higher in non-Hispanic Black participants; P<0.05). Among women, mean (SE) CVH score was 8.03 (2.4) in Hispanic, 9.34 (2.1) in non-Hispanic Asian, 7.43 (2.3) in non-Hispanic Black, and 8.00 (2.5) in non-Hispanic White adults. Education explained the largest component of CVH difference in non-Hispanic Black women (if distribution of education were similar to non-Hispanic White participants, CVH score would be 0.17 [0.03] points higher in non-Hispanic Black participants; P<0.05). Place of birth (born in the United States versus born outside the United States) explained the largest component of CVH difference in Hispanic and non-Hispanic Asian women (if distribution of place of birth were similar to non-Hispanic White participants, CVH score would be 0.36 [0.07] points lower and 0.49 [0.16] points lower, respectively; P<0.05).ConclusionsEducation and place of birth confer the largest statistical contributions to the racial and ethnic differences in mean CVH score among US adults.
