A total of 444 incident cases of IBD were ascertained and validated with the general practitioner. We performed a nested case\u2013control analysis using all cases and a random sample of 10\u2003000 frequency\u2010matched controls.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results:\u2002<\/jats:bold>\n                    Incidence rates for ulcerative colitis, Crohn's disease, and indeterminate colitis were 11, 8, and 2 cases per 100\u2003000\u2003person\u2010years, respectively. Among women, we found that long\u2010term users of oral contraceptives were at increased risk of developing UC (OR: 2.35; 95% CI: 0.89\u20136.22) and CD (OR: 3.15; 95% CI: 1.24\u20137.99). Similarly, long\u2010term users of HRT had an increased risk of CD (OR: 2.60; 95% CI: 1.04\u20136.49) but not UC. Current smokers experienced a reduced risk of UC along with an increased risk of CD. Prior appendectomy was associated with a decreased the risk of UC (OR: 0.37; 95% CI: 0.14\u20131.00).\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusions:\u2002<\/jats:bold>\n                    Our results support the hypothesis of an increased risk of inflammatory bowel disease associated with oral contraceptives use and suggest a similar effect of hormone replacement therapy on CD.
