  1. Fulltext. Caffeine consumption and menstrual function.

    Article - En anglais


    The relation between caffeine intake and menstrual function was examined in 403 healthy premenopausal women who belonged to Kaiser Permanente Medical Care Program in 1990-1991.

    A telephone interview collected information about caffeinated beverage intake as well as other lifestyle, demographic, occupational, and environmental factors.

    Subjects collected daily urine samples and completed a daily diary for an average of five menstrual cycles.

    Metabolites of estrogen and progesterone were measured in the urine, each cycle was characterized as anovulatory or ovulatory, and a probable day of ovulation was selected when appropriate.

    Logistic regression and repeated measures analyses were performed on menstrual parameters.

    Women whose caffeine consumption was heavy (>300 mg of caffeine per day) had less than a third of the risk for long menses (>8 days) compared with women who did not consume caffeine (adjusted odds ratio=0.30,95% confidence interval 0.14-0.66).

    Those whose caffeine consumption was heavy also had a doubled risk for short cycle length (<24 days) (adjusted odds ratio=2.00,95% confidence interval 0.98-4.06) ; this association was also evident in those whose caffeine consumption was heavy who did not smoke (adjusted odds ratio=2.11,95% confidence interval 1.03-4.33).
