This study used the National Epidemiological Survey on Alcohol and Related Conditions, a longitudinal adult sample, to estimate the rates of prevalent, acquired, and persisting anxiety disorders by nativity and racial-ethnic origin while adjusting for acculturation, stress, social ties, and sociodemographics. Prevalent and acquired anxiety disorders were less likely among foreign-born than US-born, except Puerto-Rican- and Mexican-born who had higher risks. Persisting cases were similar between foreign-born and US-born, except Asian/Pacific Islanders who had lower risk. Stress and preference for socializing outside one's racial-ethnic group were associated with higher while close ties were associated with lower rates of acquired/persisting anxiety disorders.
