PMDD was assessed using the Mini International Neuropsychiatry Interview version Plus (M.I.N.I. – Plus). Results: The sample included 727 women. The prevalence rate of PMDD was 17.6% and higher among older women (p=0.030) from lower socio-economic class (p=0.022). A trend toward significance was found for currently women without occupation (study or work) (p=0.081). The comorbidities significantly associated with PMDD were current major depression disorder (PR=2.35, CI 95%=1.63-3.39), agoraphobia (PR=1.86, CI 95%=1.30-2.67), bipolar disorder (PR=2.31, CI 95%=1.60-3.33), current suicide risk (RP=1.98, CI 95%=1.33-2.96), generalized anxiety disorder (PR=1.74, CI 95%=1.15-2.61), social phobia (PR=2.82, CI 95%=1.83-4.34), and specific phobia (PR=1.88, CI 95%=1.07-3.31).
