RESUMO
OBJECTIVE: Examine whether caregiver depressive symptoms at baseline predict longitudinal child asthma outcomes in the two populations with the largest asthma disparities: Mexicans and Puerto Ricans. METHODS: Two hundred and sixty-seven Hispanic caregiver-child dyads (Mexican = 188, Puerto Rican = 79; children 5-12 years) were recruited from clinics and hospitals in Phoenix, AZ and the Bronx, NY. The Center for Epidemiological Studies Depression Scale assessed caregiver depressive symptoms; higher scores indicate greater depressive symptomology. Medical records verified child asthma diagnosis. Assessments for outcome variables occurred at baseline, 3, 6, 9, and 12-month follow-ups. Pulmonary function was measured by spirometry, asthma control was measured by the Asthma Control Test, steroid bursts and acute healthcare utilization were assessed by caregiver report and medical records, and adherence was measured by doser devices on controller medications. Structural equation modeling analyzed baseline caregiver depressive symptoms as a predictor of longitudinal child asthma outcomes, and differences between subgroups. RESULTS: Higher caregiver depressive symptoms predicted better pulmonary function (ß = .02, p = .001) in Mexican children, and fewer steroid bursts (ß = -.41, p = .01) and better medication adherence (ß = .02, p = .07) in Puerto Rican children. Caregiver depressive symptoms did not predict pediatric asthma control or acute healthcare utilization in either subgroup. CONCLUSIONS: Caregiver depressive symptomology had unexpected effects on child asthma outcomes. Results may be explained by the Hispanic paradox, caregiver resilience, acculturation, and the study's longitudinal nature. Further research is needed on social determinants of health that may influence differences in child asthma outcomes in heterogeneous Hispanic communities.

OBJECTIVE: To examine baseline measures of illness-specific panic-fear (ie, the level of anxiety experienced specifically during asthma exacerbations) as a protective factor in pediatric asthma outcomes over a 1-year period. STUDY DESIGN: The sample comprised 267 children (Mexican, n = 188; Puerto Rican, n = 79; age 5-12 years) from a longitudinal observational study conducted in Phoenix, AZ and Bronx, NY. Assessments were done at baseline and 3, 6, 9, and 12 months. The Childhood Asthma Symptom Checklist was administered at baseline to children and caregivers to assess children's illness-specific panic-fear. Asthma outcome variables quantified longitudinally included pulmonary function, the Asthma Control Test, acute healthcare utilization, and medication adherence, measured by devices attached to inhaled corticosteroids. RESULTS: Child report of illness-specific panic-fear at baseline predicted higher forced expiratory volume in 1 second (FEV1) % across 1-year follow-up in Mexican children (ß = 0.17, P = .02), better asthma control in Puerto Rican children (ß = 0.45, P = .007), and less acute healthcare utilization for asthma in both groups (Mexicans: ß = -0.39, P = .03; Puerto Ricans: ß = -0.47, P = .02). Caregiver report of child panic-fear predicted higher FEV1% in Mexican (ß = 0.30; P = .02) and Puerto Rican (ß = 0.19; P = .05) children. Panic-fear was not related to medication adherence. CONCLUSIONS: Illness-specific panic-fear had beneficial effects on asthma outcomes in both groups of Latino children. The heightened vigilance associated with illness-specific panic-fear may lead children to be more aware of their asthma symptoms and lead to better strategies for asthma management.

Rationale: Researchers tend to study Latinos as a single group, but recent asthma research confirmed differences among Latino subgroups. Variations in controller medication adherence may be a factor in the observed health disparities between Mexican and Puerto Rican children. Adherence is not a stable phenomenon; however, there is a paucity of data on patterns of adherence, sociodemographic predictors of patterns, and variations in asthma-related acute healthcare use by adherence pattern among Latino subgroups. Objectives: To identify patterns of inhaled corticosteroid medication adherence over 12 months among Mexican and Puerto Rican children with persistent asthma, to examine sociodemographic predictors of adherence patterns by ethnicity, and to investigate asthma-related acute healthcare use based on these patterns. Methods: We analyzed controller medication Doser data from Mexican and Puerto Rican children (n = 123; ages 5-12 yr) with persistent asthma who participated with their caregivers in a longitudinal nonintervention study (Phoenix, AZ, and Bronx, NY). Interview and medical record data were collected at enrollment and at 3, 6, 9, and 12 months after enrollment. Results: Forty-seven to fifty-three percent of children had poor adherence (<50%) over each of the follow-up periods (cross-sectional). Children with lowest adherence were Puerto Rican, from nonpoor families, or female. Longitudinal latent class analysis yielded four adherence classes: poor, moderate, decreasing adherence, and increasing adherence. Puerto Rican children had significantly higher odds of "decreasing" (odds ratio [OR], 2.86; 95% confidence interval [CI], 0.40 to 20.50) and "poor" (OR, 5.62; 95% CI, 1.44 to 21.90) adherence than Mexican children. Females had significantly greater odds of "decreasing" (OR, 4.80; 95% CI, 0.73 to 31.74) and "poor" (OR, 5.20; 95% CI, 1.77 to 15.30) adherence group membership than males. The "decreasing" adherence group was comprised of only poor children. Children in the "poor" adherence class had the highest mean number of acute visits and emergency department visits/hospitalizations across all assessment periods. Conclusions: This study demonstrated that unique ethnicity within Latino populations may be associated with different risk levels for suboptimal controller medication adherence, which may be a factor in the observed asthma health disparities between Mexican and Puerto Rican children. Increased understanding of and attention to children's controller medication adherence patterns will provide evidence needed to identify children at highest risk for acute healthcare use and offer more-intensive intervention using less-intensive approaches for those at low risk.
