Models are logistic regressions; baseline models assess interest; follow-up models assess use. Religion is included as a categorical variable with “Catholic” used as the reference group. Education is included as a categorial variable with the highest level of education (higher than secondary) as the reference group. The Self-Injection Social Norms Scale is the average response to four items. Higher scores = more positive self-injection social norms

1997 women had complete outcome data and were in the baseline analytic sample and 1920 women had complete outcome data and were in the follow-up analytic sample
