【 摘 要 】

This study examined whether intake of caffeinated beverages (coffee, tea, and cola) was associated with fecundability (time to pregnancy) in a prospective cohort study. Data from 470 women from the Mount Sinai Study of Women Office Workers (1990-1994) were analyzed. Intake of coffee, tea, cola, and other variables were recorded in daily diaries and calculated as menstrual cycle level means for up to 20 cycles. Pregnancy was assayed using hCG and confirmed by physician diagnosis. The associations of caffeinated beverages with the probability of becoming pregnant during a given cycle were determined using discrete survival analysis, adjusted for potential confounders. Overall caffeine intake was not significantly associated with fecundability. Moderate intake of coffee, tea and cola was associated with increased fecundability, and high intake with decreased, though most associations were not statistically significant. Moderation in caffeinated beverage consumption appears to be important for women who are trying to conceive.
