*PR=prevalence ratios estimated using Poisson regression.
†PRadj=prevalence ratios adjusted for sex, age, race/ethnicity (White, mixed ethnic group, Black or Black British, Asian or Asian British and other race), region, survey year and household income.
‡Significant linear trend across all quintiles (p≤0.01).
