A group of 147 young women with symptomatic urinary tract infection (UTI) were compared with a control group of 105 symptom-free young women belonging to the same population. On logistic-regression analysis, sexual activity was the only significant and independent behavioral difference between the groups (87% of women with UTI were sexually active vs 32.7% of the control group). Of the 147 episodes of UTI, only 28.9% occurred within 24 hours of sexual intercourse; of 24 episodes that occurred during follow-up, the percentage that occurred within 24 hours of intercourse was 33.3%. This finding is in discordance with the close temporal association between UTI and sexual intercourse reported in previous studies.
将一组147名有症状的年轻女性尿路感染患者与另一组105名来自相同人群的无症状年轻女性进行对照。逻辑回归分析显示，性行为是两组之间唯一显著且独立的行为差异（87%的尿路感染女性有性行为，而对照组为32.7%）。在147例尿路感染病例中，只有28.9%发生在性交后24小时内；在随访期间发生的24例病例中，性交后24小时内发生的比例为33.3%。这一发现与先前研究报道的尿路感染与性交之间紧密的时间关联不一致。
