Diagnosis and intensity of symptoms were separately compared for dietary and other factors. The χ2 test or Fisher exact test as required and a multivariate analysis were performed. RESULTS: Seventeen percent of the sample reported no symptoms; core PMD was diagnosed in 14%, and related to symptoms of moderate intensity, to late menarche, irregular, long cycles, dysmenorrhoea, and to lower intake of complex carbohydrates, fibers, calcium; non-cyclical pattern in 27%, and related to symptoms of severe intensity, to young age, unemployed, to poor health, stress, traumatic events, abnormal BMI, to long, heavy menses, to lower intake of fibers, magnesium, vitamin B6, and to higher intake of fat, proteins, sodium, caffeine; variant PMD-premenstrual exacerbation in 42%, and related to symptoms of severe - moderate intensity, to young age, students, unemployed, sedentary work, abnormal BMI, stress, to cycle irregularities, heavy menses, to higher intake of simple sugars and sodium, and to lower intake of calcium, magnesium, and vitamin B6.
