  1. Cigarette smoking and urinary oestrogen excretion in premenopausal and post-menopausal women.

    Article - En anglais

    Cigarette smoking is associated with a reduction in the risk for endometrial cancer in post-menopausal women and it has been suggested that this is because smoking has an anti-oestrogenic effect.

    To investigate this, concentrations of oestrone, oestradiol and oestriol were measured in 24 h urine samples from 167 premenopausal women (53 smokers, 114 non-smokers) and 200 post-menopausal women (54 smokers, 146 non-smokers).

    Among premenopausal women there were no significant differences in oestrogen excretion between smokers and non-smokers.

    Among post-menopausal women, geometric mean excretion rates for oestrone and oestradiol did not differ significantly between groups, but oestriol excretion was 19% lower (95% confidence interval - 34% to - 1%) in smokers than in non-smokers.

    This may partly explain the reduced risk for endometrial cancer among post-menopausal smokers.
