Soy, fat and other dietary factors in relation to premenstrual symptoms in Japanese women.
OBJECTIVE
To evaluate the relations of intakes of soy, fat and other dietary components to premenstrual symptoms.


METHODS
Cross sectional study.


METHODS
Three colleges and two nursing schools.


METHODS
One hundred and eighty-nine Japanese women aged 19 to 34 years.


METHODS
Intakes of nutrients and foods, including soy products and isoflavones, were estimated by a semiquantitative food frequency questionnaire. Change in menstrual cycle symptoms were assessed by the Moos Menstrual Distress Questionnaire (MDQ).


METHODS
Spearman rank correlation of soy and other dietary factors with changes in MDQ scores between the follicular and the premenstrual phases after controlling for age, marital status, exercise, smoking status, age at menarche and number of days of bleeding.


RESULTS
Neither soy product nor isoflavone intake was significantly associated with change in MDQ score in the premenstrual phase. Intakes of total, saturated and monounsaturated fats were significantly correlated with change in scores for total MDQ and subscale 'pain' in the premenstrual phase after controlling for the covariates. Intake of cereals/potatoes/starches was significantly inversely correlated with a change in total MDQ score in the premenstrual phase.


CONCLUSIONS
High intake of fats and low intake of foods with high concentration of carbohydrate may be associated with premenstrual symptoms.
