HealthDay News — Alcohol intake may be linked to the risk of premenstrual syndrome (PMS), according to a review published online April 23 in BMJ Open.

María del Mar Fernández, from the University of Santiago de Compostela in Spain, and colleagues conducted a systematic literature review to assess the role of alcohol in the occurrence of PMS.

Based upon 19 eligible studies, intake of alcohol was associated with a moderate increase in the risk of PMS (odds ratio, 1.45). This association was most pronounced with heavy drinking (odds ratio, 1.79). It is plausible there is a reverse causation process, in which PMS-affected women use alcohol to mitigate the effect of the syndrome.

"Our results suggest that alcohol intake presents a moderate association with PMS risk," the authors write. "Future studies should avoid cross-sectional designs and focus on determining whether there is a threshold of alcohol intake under which the harmful effect on PMS is non-existent."
