Symptomatology across the menstrual cycle in smoking and nonsmoking women.

Recent studies suggest that both smoking rates and general menstrual symptomatology increase in women premenstrually; however, no study has investigated the changes in menstrual symptomatology and smoking behavior in both smoking and nonsmoking women over an entire menstrual cycle. Thirty premenopausal women completed daily symptom checklists over an entire menstrual cycle. Smokers also recorded their smoking behavior. Results indicated that symptom severity was greatest during menses for both smoking and nonsmoking women. For cigarette consumption, analyses indicated that women smokers appear to smoke more during menses and the luteal phases than ovulation and that variability in smoking was greatest premenstrually. In summary, results indicated that general menstrual symptomatology increases during menses and the late luteal phase and that smoking-deprivation symptomatology increase in both smokers and nonsmokers. This suggests that smokers may have a difficult time quitting during menses or the luteal phase of their cycle.
