We evaluated the hypothesis that tea consumption causes premenstrual syndrome by studying 188 nursing students and tea factory workers in the People's Republic of China via questionnaires distributed in classes (nursing students) or during routine physical examinations (tea factory workers). Analysis of the data revealed that tea consumption is strongly related to the prevalence of premenstrual syndrome and that the effects are dose-dependent.
我们通过向中华人民共和国的188名护理专业学生和茶厂工人发放问卷(护理专业学生通过课堂发放,茶厂工人通过常规体检发放),来评估饮茶会导致经前综合征这一假设。数据分析显示,饮茶与经前综合征的患病率密切相关,且这种影响具有剂量依赖性。
