Social Risks and Health Care Utilization Among a National Sample of Children With Asthma.

Objectives: Prior studies using single-center populations have established associations between social risks and health care utilization among children with asthma. We aimed to evaluate associations between social risks and health care utilization among a nationally representative sample of children with asthma.

Study Design: In this cross-sectional study, we utilized the 2018-2019 National Survey of Children's Health to identify children 2 to 17 years old with asthma. Using the Healthy People (HP) 2030 social determinants of health (SDOH) framework, we identified 31 survey items assessing 18 caregiver-identified social risks as exposure variables and classified them into the 5 HP SDOH domains (Economy, Education, Health care, Community, and Environment). Primary outcome was caregiver-reported health care utilization. Associations between individual social risks and total number of SDOH domains experienced with health care utilization were assessed.

Results: The weighted study population included 8.05 million children, 96% of whom reported ≥1 social risk. Fourteen social risks, spanning all 5 SDOH domains, were significantly associated with increased health care utilization. The 3 risks with the highest adjusted odds ratios (aOR) of health care utilization included: experiencing discrimination (aOR 3.26 [95% confidence interval (CI): 1.75, 6.08]); receiving free/reduced lunch (aOR 2.16, [95% CI 1.57, 2.98]); and being a victim of violence (aOR 2.11, [95% CI 1.11, 4]). Children with risks across more SDOH domains reported significantly higher health care utilization.

Conclusions: Among our national population of children with asthma, social risks are prevalent and associated with increased health care utilization, highlighting their potential contribution to pediatric asthma morbidity.
