The prevalence of asthma risk and contributing factors in underserved Vietnamese children in Orange County, CA

Patterns and drivers of disparities in pediatric asthma outcomes among Medicaid-enrolled children living in subsidized housing in NYC

OBJECTIVE

There are persistent disparities in pediatric asthma morbidity in the U.S. We linked claims data with information on neighborhood-level risk factors to explore drivers of asthma disparities among Medicaid-enrolled children in New York City subsidized housing.

METHODS

We constructed a cohort of Medicaid-enrolled children living in public or other subsidized housing, based on residential address, in NYC between 2016 and 2019 (n = 108,969). We examined claims-derived asthma prevalence across age and racial and ethnic groups, integrating census tract-level information and using the Bayesian Improved Surname Geocoding (BISG) algorithm to address high rates of missing data in self-reported race and ethnicity. We used inverse probability weighting (IPW) to explore the extent to which disparities persisted when exposure to asthma risk factors - related to the built environment, neighborhood poverty, and air quality - were balanced across groups. This analysis was conducted in 2022-2023.

RESULTS

Claims-derived asthma prevalence was highest among children <7 years at baseline and among non-Hispanic Black and Hispanic children. For example, among children aged 3-6 years at baseline, claims-derived prevalence was 17.3% and 18.1% among non-Hispanic Black and Hispanic children, respectively, compared to 9.3% and 9.0% among non-Hispanic White and non-Hispanic Asian American/Pacific Islander children. Using IPW to balance exposure to asthma risk factors across racial and ethnic groups attenuated, but did not eliminate, disparities in asthma prevalence.

CONCLUSIONS

We found high asthma burden among children living in subsidized housing. Modifiable place-based characteristics may be important contributors to pediatric asthma disparities.

Asthma-Related Emergency Department Visits Among Low-Income Families With Young Children by Race/Ethnicity and Primary Language

OBJECTIVE

The aim of this study was to examine the existence of racial/ethnic and language disparities in asthma-related emergency department (ED) initial and return visits among young children in low-income families in California.

METHODS

Children younger than 6 years with at least 1 asthma-related ED visit recorded in the California Office of Statewide Health Planning and Development data set between January 1, 2009, and December 31, 2013, and on Medicaid (Medi-Cal) were assessed. Primary outcomes were hospitalization at the first asthma-related ED visit and a return asthma-related ED visit within 12 months. Data were analyzed using multivariate logistic regression.

RESULTS

Among 47,657 children, approximately 55% were Hispanic, 20% were black, and 2.7% were Asian/Pacific Islander. For non-English-speaking families, 82% were Hispanic. Among English-speaking families, blacks were less likely to be hospitalized at the first ED visit (odds ratio [OR], 0.787; 95% confidence interval [CI], 0.715-0.866) but more likely to return to the ED (OR, 1.291; 95% CI, 1.205-1.383) compared with whites. Conversely, Asian/Pacific Islanders whose primary language was English were more likely to be hospitalized (OR, 2.150; 95% CI, 1.827-2.530) compared with whites. Among families whose primary language was not English, Hispanic and Asian/Pacific Islanders are more likely to be hospitalized at the first ED visit and all groups are less likely to return to the ED compared with English-speaking whites.

CONCLUSIONS

The findings suggest that racial/ethnic and language disparities exist in eventual asthma-related hospitalizations and repeat ED visits. Continued research is needed to understand the existence of these differences and to inform future comprehensive and linguistically appropriate asthma interventions for children in low-income families.
