Scientists from the Massachusetts Central hospital and medical Department of Harvard University analyzed the danger of the use of oral contraceptives in connection with the risk of developing ulcerative colitis and Crohn's disease.
In the study, researchers analysed data on the health status 117 375 American women who received treatment or examination at the Massachusetts hospital in the period from 1976 to 1989. They had no history of disease colitis or Crohn's disease. Information on the status of women's health was checked every two years, were also analyzed all the risk factors for these diseases were taken into consideration was given birth are women and at what age they gave birth to their first child.
It turned out that among 232 452 women were identified 392 cases of ulcerative colitis in the period from 2007 to 2008. Comparing these data with the results among women who have never responded to oral contraceptive, we can say that the risk of illness from such contraceptive increases two times. If using contraceptives level of disease colitis was 2.82%, among non-contraceptive use of this order - of 1.39 percent. Oral contraceptives increased the risk of developing these diseases, if the patient was a smoker for about 0.4 percent. The link between pregnancy and age at first birth have been identified.
