Description: Dysmenorrhea occurs in an estimated 30-75% of menstruating women. Nursing is frequently confronted with this health problem but knowledge is needed to provide effective interventions to alleviate the pain and incapacity which accompanies the disorder. Evidence indicates that nutrition and stress may be causative factors in dysmenorrhea. The purposes of the study were to determine (1) if women who experience dysmenorrhea differ from women who do not experience dysmenorrhea on stress, diet, and the physiological parameters of vitamin B$\sb6$, magnesium, calcium, copper and zinc; and (2) if supplementation with magnesium and vitamin B$\sb6$ will decrease symptoms of dysmenorrhea.

The study was conducted in two phases. Phase 1 was a nonexperimental prospective comparison of women with (n = 49) and without (n = 57) dysmenorrhea. Stress and diet were measured during the luteal phase and physiological parameters were measured at the luteal and menstrual phase. Phase 2 was a double-blind, repeated measures clinical trial in which the diets of dysmenorrheic women (n = 47) were supplemented for 4 months with either a placebo, vitamin B$\sb6$, magnesium, or both magnesium and vitamin B$\sb6$. Menstrual pain, stress and mineral levels were measured at 5 consecutive menstruations; once before supplementation and again at the next 4 menstruations. Data were analyzed using Pearson correlations, t-tests and repeated measures MANOVA.

Women with dysmenorrhea compared to women without dysmenorrhea had longer menstrual flows, lower (p $<$.05) hematocrits, more days lost from work/school, and higher stress levels. Women with dysmenorrhea also consumed fewer fruits and vegetables, which resulted in their having significantly lower (p $<$.05) intakes of dietary fiber, vitamin B$\sb6$, vitamin A and vitamin C. Plasma minerals were significantly different (p $<$.05) between the groups, but PLP and erythrocyte magnesium were similar. Women supplemented with Vitamin B$\sb6$ showed a 45% decrease in menstrual pain over four months, but the other groups showed no significant over all change. Stress responses and plasma zinc diminished significantly (p $<$.05) during supplementation and were similar to values seen in women without dysmenorrhea.

These results suggest that nutrition and stress play a role in the physiological and psychological mechanisms of dysmenorrhea. This knowledge provides the nursing profession with direction for future studies involving the causes and treatment of dysmenorrhea.
