The premenstrual assessment form (PAF) was used to assess the degree and type of premenstrual changes reported by 101 oral contraceptive users and 149 non-users (aged 18-45 yr) attending general health and gynaecology clinics. Women using oral contraceptives did not complain of fewer or less severe symptoms overall, but their severity scores on the subscales of premenstrual anxiety, fatigue, low mood, water retention, and impaired social functioning were significantly lower than those of non-users. The duration of oral contraceptive use and the type of preparation (combined or phased) taken were not related to the degree of premenstrual change reported. Complaints of symptoms beginning more than two days before menstruation were less frequently reported by pill-users (p less than 0.01) and were associated with a greater severity of all types of premenstrual change (p less than 0.0001). Women who had experienced difficulties tolerating oral contraceptives reported a greater number of moderate/severe premenstrual changes (p less than 0.0001).
采用经前评估表（PAF）对101名口服避孕药使用者和149名未使用者（年龄在18 - 45岁之间）进行评估，这些人前往普通健康和妇科诊所就诊。总体而言，口服避孕药的女性抱怨的症状数量并不更少，症状严重程度也没有更低，但她们在经前焦虑、疲劳、情绪低落、水潴留和社会功能受损等分量表上的严重程度得分显著低于未使用者。口服避孕药的使用时长和所服用制剂的类型（复方或分阶段制剂）与所报告的经前变化程度无关。 pill使用者较少报告在月经前两天以上开始出现症状（p小于0.01），并且所有类型的经前变化严重程度更高（p小于0.0001）。曾有口服避孕药耐受困难的女性报告的中度/重度经前变化数量更多（p小于0.0001）。
