The prevalence of individual premenstrual symptoms was studied in a randomly selected group of 217 women taking oral contraceptives (OC). The results were compared with corresponding data from 595 women not using the pill. the analyses included six different mental and somatic symptoms defined and graded in severity and related to age. It was found that OC had a beneficial effect on the premenstrual tension symptoms (PMT) in all age groups except in the youngest group (18 years), in which the tendency was rather the opposite. Within the total sample of women, users of OC were significantly less frequently absent from work. The present results are in agreement with those of most earlier studies, provided that age is taken into account.
在一组随机抽取的217名服用口服避孕药（OC）的女性中，研究了个体经前症状的患病率。将结果与595名未服用避孕药的女性的相应数据进行了比较。分析包括六种不同的精神和躯体症状，这些症状根据严重程度进行定义和分级，并与年龄相关。结果发现，除最年轻的年龄组（18岁）外，OC对所有年龄组的经前紧张症状（PMT）都有有益影响，而在最年轻组中情况则相反。在女性总样本中，服用OC的女性缺勤频率显著较低。如果考虑年龄因素，目前的结果与大多数早期研究的结果一致。
