Use of Protection for Unwanted Pregnancy and Sexually Transmitted Infections in Six Birth Cohorts in Norway 2020: A Descriptive Study

This study describes the use of contraception and protection for sexually transmitted infections (STIs) in six different birth cohorts of the general population in Norway. The results are based on a 2020 national web panel survey among 18–89 year-olds in Norway (n = 4160). For respondents born within 1931–1950 versus those born within 1990–2002, there was a significant increase in the use of protection against unwanted pregnancy and STIs during sexual intercourse, and a significant drop in the proportion of those who did not use any protection at all. More women today (than in previous decades) are using hormonal contraception. The main reason for not using condoms during intercourse was both parties felt safe that they were healthy, especially those born within 1990–2002. To prevent unwanted pregnancy and STIs, it is beneficial to continue to increase the availability of free or subsidized hormonal contraception, including emergency contraception, and free condoms in public arenas that people frequent and where they meet their partners.
