title: A study of the menopause, smoking, and contraception in women with Crohn's disease.
abstract: One hundred and ninety-six women with Crohn's disease from south-east Wales were asked to provide details of their menstrual cycles, age at menopause, history of surgery, smoking habits and use of oral contraceptives. One hundred and forty-six provided the information (response rate 77 per cent). Eighty-four were still menstruating, three were pregnant, 10 had undergone hysterectomy, one had a pharmacologically-induced menopause and 48 had had a physiological menopause. Of these 48 women, 33 were diagnosed as having Crohn's disease before the menopause. Twenty-five of these were smokers. The mean age at menopause was similar in smokers and non-smokers and in those diagnosed before and after the menopause. The mean age at menopause was between 46 and 47. A logistic analysis using the 'status quo' method showed that 50 per cent of women with Crohn's disease had the menopause at 47.6 years compared with 49.6 years in a group of healthy women from the same area. The two groups had similar smoking habits and it would seem that a premature menopause is associated with Crohn's disease.
