Multivariable logistic regression adjusted for the confounding effects of age, rural/urban location, deprivation, education attainment, contraceptive method used in the past year, ever use of emergency contraception, unsafe sex in the past year, age at first sex, sexual competence at first heterosexual sex, number of sexual partners in the past year, relationship status, frequency of sexual intercourse, STI symptoms and, among women, pregnancy (ever) and abortion (ever). *Participants aged ≥17 years.
†English General Certificate of Secondary Education or equivalent.
‡p<0.05 in univariate analyses.
