We have shown that menopausal hormone therapy (MHT) is associated with the risk of inflammatory bowel disease. In this study, we prospectively examined the association between MHT and the risk of incident diverticulitis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>We studied 65,367 postmenopausal women enrolled in the Nurses' Health Study who provided detailed information on hormone use and other medical and lifestyle factors biennially, and on diet every 4 years. Between 2008 and 2014, participants reported any episodes of diverticulitis that required antibiotics and the date of occurrence.

The increased risk was observed among participants using estrogen only (HR 1.30; 95% CI 1.20\u20131.41) and those using combined estrogen and progesterone (HR 1.31; 95% CI 1.21\u20131.42) compared to nonusers.
