Our study evaluated the effect of pregnancy\/paternity intention on contraceptive choice amongst new, sexually active and non-pregnant recruits. A total of 592 males and 503 females completed self-administered surveys asking about pregnancy\/paternity intention, contraceptive use at last intercourse, and potential confounding factors. A multidimensional measurement of pregnancy intention was developed. Contraceptive efficacy was categorised as a four-level ordinal variable. Multivariate ordinal regression measured the association between pregnancy\/paternity intention and the most efficacious birth control method used at last intercourse.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Only 7% of participants planned a pregnancy in the next 6 months, but almost 33% of them used no birth control at last intercourse.
