Background/objectives: Little is known about the predictors and trends of psychological comorbidities in childhood atopic dermatitis (AD), or whether they occur in an age-dependent pattern. We hypothesized racial/ethnic and socioeconomic disparities lead to increased psychological problems among children with AD and psychological comorbidities occur in an age-dependent manner.
Methods: We analyzed cross-sectional data on 228 898 children aged 2-17 years from the 1997-2018 National Health Interview Survey.
Results: Children with AD had higher proportions of depression/sadness (17.2% vs 12.6%; odds ratio [95% confidence interval]: 1.44 [1.37-1.51]), attention deficit (hyperactivity) disorder (ADD/ADHD) (10.0% vs 7.1%; 1.46 [1.38-1.55]), emotional/behavioral difficulties (29.9% vs 23.5%; 1.77 [1.69-1.84]), feelings of frequent worry (38.8% vs 23.5%; 1.66 [1.58-1.74]), and autism (1.9% vs 0.9%; 2.00 [1.75-2.29]). Among children with AD, psychologic comorbidity was associated with atopic comorbidities and multimorbidity and white race, households with lower income and education, and no insurance coverage. In children with or without AD, the prevalence of autism peaked during pre-adolescence; ADD/ADHD and emotional/behavioral difficulties peaked in adolescence; and depression/sadness and feelings of frequent worry increased steadily throughout childhood without plateau.
Conclusion: Atopic dermatitis was associated with multiple psychologic disorders, particularly among those with atopic comorbidities, white race, and low household income. Psychologic comorbidities increased in an age-dependent pattern, though similar to children without AD.
