Stress, quality of life and physical activity in women with varying degrees of premenstrual symptomatology.

Premenstrual symptomatology, stress, quality of life (QOL) and exercise frequency, volume, and intensity were assessed in 114 females (18-33 years). Based on premenstrual symptoms (PMS), women were divided into high and low PMS groups and compared on stress, QOL and exercise variables. Results revealed women with high PMS had significantly more stress and poorer QOL than women with low PMS (p <.05 for both comparisons). Groups did not significantly differ on any of the exercise variables. Further analyses were performed to determine if exercise variables impacted PMS symptoms, stress and QOL reports in the high PMS group. While exercise volume and intensity did not impact any of the variables assessed, women with high PMS who reported exercising "sometimes" had more stress than women who reported exercising "often" or "never". This nonlinear relationship suggests that women with the worst symptoms may respond by exercising, while women who exercise often or never do not associate exercise with their symptoms.
