Background: The Asian American (AsA) population is heterogenous and rapidly growing; however, little is known regarding childhood asthma burden among AsA ethnic groups. The relation between obesity and asthma in AsA ethnic groups also remains unclear., Objective: To evaluate asthma prevalence and the relation of obesity to asthma risk among children in 7 AsA ethnic groups., Methods: We analyzed data from the California Health Interview Survey from 2011 to 2020. AsA ethnicities were self-reported. Body mass index z-scores, calculated from self-reported height/weight, were used to categorize children by obesity status, based on body mass index-for-age growth charts. Prevalence of self-reported lifetime doctor-diagnosed asthma and asthma attack in the last 12 months was calculated. We performed multivariable logistic regressions adjusting for age and sex., Results: Of 34,146 survey respondents, 12.2% non-Hispanic White and 12.5% AsA children reported lifetime asthma. Among AsA ethnic groups, however, lifetime asthma ranged from 5.1% (Korean American) to 21.5% (Filipino American). Non-Hispanic White children and AsA children had a similar lifetime asthma prevalence (adjusted odds ratio [aOR], 1.05; 95% CI, 0.71-1.55; P = .81), but prevalence was lower in Korean American children (aOR, 0.37; 95% CI, 0.19-0.73; P = .004) and higher in Filipino American children (aOR, 1.97; 95% CI, 1.22-3.17; P = .006). The lifetime asthma prevalence of different AsA ethnic groups persisted even when stratified by obesity status., Conclusion: Childhood lifetime asthma prevalence varied among AsA ethnic groups, with lowest prevalence in Korean American children and highest prevalence in Filipino American. Further characterization of asthma burden among AsA ethnic groups may help guide asthma screening and prevention measures and offer new insights into asthma pathogenesis., Competing Interests: Disclosures The authors have no conflicts of interest to disclose., (Copyright © 2023 American College of Allergy, Asthma & Immunology.

Background: Anaphylaxis is a potentially fatal acute allergic reaction. Its overall prevalence appears to be rising, but little is known about US hospitalization trends among infants and toddlers., Objective: To identify the trends and predictors of hospitalization for anaphylaxis among infants and toddlers., Methods: We used the nationally representative National Inpatient Sample (NIS), from 2006 to 2015, to perform an analysis of trends in US hospitalizations for anaphylaxis among infants and toddlers (age, <3 years) and other children (age, 3-18 years). For internal consistency, we identified patients with anaphylaxis by the International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis code and excluded those with the International Classification of Diseases, Tenth Revision, Clinical Modification (late 2015). We calculated trends in anaphylaxis hospitalizations over time by age group and then used multivariable logistic regression to describe anaphylaxis hospitalizations among infants and toddlers., Results: Among infants and toddlers, there was no significant change in anaphylaxis hospitalizations during the 10-year study period (P trend  = .14). Anaphylaxis hospitalization among infants and toddlers was more likely in males, with private insurance, in the highest income quartile, with chronic pulmonary disease, who presented on a weekend day, to an urban teaching hospital, located in the Northeast. In contrast, anaphylaxis hospitalizations among older children (age, 3-<18 years) rose significantly during the study (P trend < .001)., Conclusion: Anaphylaxis hospitalizations among infants and toddlers in the United States were stable from 2006 to 2015, whereas hospitalizations among older children were rising. Future research should focus on the trends in disease prevalence and health care utilization in the understudied population of infants and toddlers., (Copyright © 2020 American College of Allergy, Asthma & Immunology.
