It is estimated that up to 75% of premenopausal women experience at least one premenstrual symptom and 8-20% meet clinical criteria for premenstrual syndrome. Premenstrual syndrome substantially reduces quality of life for many women of reproductive age, with pharmaceutical treatments having limited efficacy and substantial side effects. Physical activity has been recommended as a method of reducing menstrual symptom severity. However, this recommendation is based on relatively little evidence, and the relationship between physical activity, premenstrual symptoms, and premenstrual syndrome remains unclear.
We evaluated the relationship between physical activity and premenstrual syndrome and premenstrual symptoms among 414 women aged 18-31. Usual premenstrual symptom experience was assessed with a modified version of the Calendar of Premenstrual Experiences. Total, physical, and affective premenstrual symptom scores were calculated for all participants. Eighty women met criteria for moderate-to-severe premenstrual syndrome, while 89 met control criteria. Physical activity, along with dietary and lifestyle factors, was assessed by self-report.
Physical activity was not significantly associated with total, affective, or physical premenstrual symptom score. Compared to the women with the lowest activity, women in tertiles 2 and 3 of activity, classified as metabolic equivalent task hours, had prevalence odds ratios for premenstrual syndrome of 1.5 (95% CI: 0.6-3.7) and 0.9 (95% CI: 0.4-2.4), respectively (p-value for trend = 0.85).
We found no association between physical activity and either premenstrual symptom scores or the prevalence of premenstrual syndrome.
据估计，高达75%的绝经前女性至少经历过一种经前症状，8 - 20%符合经前综合征的临床标准。经前综合征严重降低了许多育龄女性的生活质量，药物治疗疗效有限且副作用大。体育活动被推荐为减轻经期症状严重程度的一种方法。然而，这一推荐基于的证据相对较少，体育活动、经前症状和经前综合征之间的关系仍不明确。
我们评估了414名年龄在18 - 31岁女性中体育活动与经前综合征及经前症状之间的关系。采用经修改的《经前经历日历》评估通常的经前症状体验。计算所有参与者的经前症状总分、身体症状分和情感症状分。80名女性符合中重度经前综合征标准，89名符合对照标准。通过自我报告评估体育活动以及饮食和生活方式因素。
体育活动与经前症状总分、情感症状分或身体症状分均无显著关联。与活动量最低的女性相比，活动量处于第二和第三三分位数（以代谢当量任务小时分类）的女性，经前综合征的患病优势比分别为1.5（95%置信区间：0.6 - 3.7）和0.9（95%置信区间：0.4 - 2.4）（趋势p值 = 0.85）。
我们发现体育活动与经前症状评分或经前综合征患病率之间无关联。
