The relationship between urinary tract infections and the collegiate academic calendar

College students believe that they are more likely to be ill during examination periods than at other times in the academic year. We in the health service hypothesized that urinary tract infections are not affected by the demands of the academic calendar. During a 4-year study, the university health service obtained urine culture data prospectively from 456 patients who had a total of 508 episodes of urinary tract infections. Each year, the number of urinary tract infections decreased during both midterm and final examination periods, but rebounded to higher-than-average levels in the second week following the midterm examination period, as well as during the second week of the second (spring) semester, immediately after the mid-winter recess. Mean duration of symptoms was 34 hours (range, from 12 to 60). Urinary tract infections were less common during examination periods, when students were preoccupied with academic responsibilities, but such infections increased in frequency in the period immediately after examinations, when sexual intimacy was resumed or when sexual intercourse with a new partner began. Urinary tract infections in college women, the study indicated, are primarily related to sexual intercourse, and susceptibility is only indirectly affected by the demands of the academic calendar.
