Compared to non-Hispanic whites, atopic dermatitis (AD) incidence and persistence is higher among certain non-white racial/ethnic subgroups, a recent study found. Using data from Project Viva, a prospective pre-birth cohort in eastern Massachusetts, researchers studied 1,437 mother-child pairs with known AD status to examine the associations of race/ethnicity with maternally-reported child AD. They used multivariable logistic regression, adjusting for socio-demographic factors and maternal plasma vitamin D, to estimate adjusted odds ratios (aOR) of AD incidence at early childhood and persistence at mid-childhood. They found:
- Compared to non-Hispanic whites, non-Hispanic blacks (aOR 2.71) and other non-Hispanics (aOR 1.80) were more likely to have incident AD.
- Non-Hispanic blacks (aOR 6.26) and Hispanics (aOR 6.42) with early childhood AD were more likely to have persistent AD.
