  • All figures are weighted for sampling probabilities and differential non-response.

  • *P<0.05, **p<0.01, ***p<0.001.

  • †Multivariable multinomial logistic regression was performed. 0–1 sexual partners was the reference group in all analyses (n=775).

  • ‡Unweighted sample sizes. Models were performed on complete cases and as such the analysed sample number differs from the number included in the bivariate analyses.

  • §Reference category: married/cohabiting.

  • ¶Reference category: heterosexual.

  • ††Reference category: white.

  • ‡‡Reference category: 1 (poorest).

  • §§Reference category: never smoker.

  • ¶¶Reference category: never/rarely.

  • †††Reference category: inactive.
