Reduced asthma morbidity during COVID-19 in minority children: is medication adherence a reason?

OBJECTIVES: Asthma control improved during the COVID-19 pandemic. This study examined objectively measured medication adherence, asthma morbidity and quality of life (QoL) outcomes in Black and Latinx children by month for January-June 2019 (pre-COVID) compared to January-June 2020 (including first peak of COVID). METHODS: Secondary analyses of 94 children with asthma (ages 10-17 years, 64% Latinx, 36% Black) and their caregivers assigned to the comparison group of a longitudinal RCT intervention trial. Outcomes included mean aggregate electronic adherence for controller medications, oral steroid bursts, acute healthcare utilization, caregiver asthma QoL, and the Asthma Control Test. Repeated measures analyses were conducted due to multiple observations. RESULTS: Adherence to controller medications declined 48% from 2019 to 2020 (LS Mean = 33.9% vs. 17.6%, p=.0004, f=.92) with levels reaching a low in May 2020. A reduction in steroid bursts was observed over the same timeframe, 1.29 vs. 0.61, p = 0.006, f=.63. Caregiver QoL increased from 2019 to 2020 on total score (5.18 vs. 5.85, p = 0.002, f=.72), activity limitations (5.04 vs. 5.95), and emotional functioning (5.26 vs. 5.80). Although not statistically significant, a clinically meaningful 62% reduction in acute healthcare visits (p = 0.15) was reported in 2020. Children reported better asthma control (OR = 1.47, 95% CI 1.24, 1.73, p < 0.0001) in 2020 versus 2019 driven by improvements from May to June 2020. CONCLUSIONS: Decreased asthma morbidity in minority children during COVID was coupled with decreased adherence to controller medications. This observed decrease in morbidity is not explained by improvements in adherence.

Attention-Deficit Hyperactivity Disorder Symptoms, Underperception of Respiratory Compromise, and Illness Representations in Black and Latino Children With Asthma.

OBJECTIVE: This study examined the associations between attention-deficit/hyperactivity disorder (ADHD) symptoms, underperception of respiratory compromise, and illness representations in Black and Latino children with asthma. We hypothesized that increased child-reported ADHD symptoms, as well as parent reports for their child, would be associated with underperception of respiratory compromise, and maladaptive asthma beliefs. METHODS: Two hundred ninety-six parent-child dyads were recruited from pediatric asthma and primary care clinics in the Bronx. Participants completed demographic questionnaires, the Conners-3 ADHD Index to measure ADHD symptoms, and the Asthma Illness Representation Scale to assess asthma beliefs. Perception of respiratory compromise was assessed by programmable electronic peak flow monitors that measured the child's subjective estimates of peak expiratory flow (PEF) and actual PEF, with underperception as the primary measure. RESULTS: Child-reported ADHD symptoms were associated with greater underperception (ß = .117, p = .049) of respiratory compromise. Parent-reported ADHD symptoms were associated with greater underperception (ß = .129, p = .028) of respiratory compromise. Child-reported ADHD symptoms (ß = -.188, p < .001) were associated with more maladaptive asthma beliefs, F(1, 341) = 13.135. Parent-reported ADHD symptoms (ß = -.203, p ≤ .001) were associated with more maladaptive asthma beliefs, F(1, 341) = 15.644. CONCLUSIONS: ADHD symptoms were associated with a greater underperception of respiratory compromise and more maladaptive asthma beliefs. Deficits of attentional processes and/or hyperactivity levels might be contributing factors. We emphasize the need for psychoeducation and interventions that improve perception and health beliefs in children with comorbid ADHD and asthma.
