“…However, no published evidence has been found in support of such a hypothesis or in support of a hypothesis of an association between cystitis and BMI. A recent report [15] on risk factors for urinary tract infection did not address the issue. Considering the strength of the association, we think that the relationship of UI to obesity deserves further consideration in prospective population and patient studies.…”

The aim of the present investigation was to study the possible role of obesity in the etiology of adult female urinary incontinence (UI). A random population sample of 3,114 women aged 30-59 years were mailed a questionnaire concerning UI and, among other things, body weight and height. The overall rate of response was 85%, and the present analysis comprises 2,589 women who supplied information about their body weight and height. The period prevalence of all UI, stress UI, urge UI, and mixed stress and urge UI was 17%, 15%, 9%, and 7%, respectively. The mean body mass index (BMI) was 22.7 kg/m2. Irrespective of other risk indicators, BMI was positively associated with UI prevalence (OR, 1.07/BMI unit; P < 0.0001). BMI interacted with childbirth in predicting stress UI prevalence, with cystitis in predicting urge UI, and with both in predicting mixed UI. Stress UI proved to be the UI type most closely associated with BMI.

“…The main risk factors for UTI are recent and frequent sexual intercourse, contraceptive use, and a history of UTIs (2,3). Treatment for UTIs usually involves a short course of an antimicrobial drug, such as trimethoprim-sulfamethoxazole (TMP-SMZ).…”

Women with urinary tract infections (UTIs) in California, USA (1999USA ( -2001, were infected with closely related or indistinguishable strains of Escherichia coli (clonal groups), which suggests point source dissemination. We compared strains of UTI-causing E. coli in California with strains causing such infections in Montréal, Québec, Canada. Urine specimens from women with community-acquired UTIs in Montréal (2006) were cultured for E. coli. Isolates that caused 256 consecutive episodes of UTI were characterized by antimicrobial drug susceptibility profi le, enterobacterial repetitive intergenic consensus 2 PCR, serotyping, XbaI and NotI pulsed-fi eld gel electrophoresis, multilocus sequence typing, and phylogenetic typing. We confi rmed the presence of drug-resistant, genetically related, and temporally clustered E. coli clonal groups that caused community-acquired UTIs in unrelated women in 2 locations and 2 different times. Two clonal groups were identifi ed in both locations. Epidemic transmission followed by endemic transmission of UTI-causing clonal groups may explain these clusters of UTI cases.

“…Influence of hydration on the susceptibility to UTI In a case-control study, Remis et al (1987) investigated the possible influence of behavioural factors on the risk of UTI. In all, 43 women with culture-confirmed UTI were compared with women with upper respiratory infection and women visiting a gynaecology clinic (controls).…”

Bacterial growth in the urinary tract is usually prevented by host factors including bacterial eradication by urinary and mucus flow, urothelial bactericidal activity, urinary secretory IgA, and blood group antigens in secretions which interfere with bacterial adherence. Bacterial eradication from the urinary tract is partially dependent on urine flow and voiding frequency. Therefore, it seems logical to postulate a connection between fluid intake and the risk of urinary tract infections (UTIs). However, experimental and clinical data on this subject are conflicting. Experimental studies concerning the effect of water intake on susceptibility and course of UTIs were predominantly performed in the 60 s and 70 s. Despite many open questions, there has been no continuous research in this field. Only few clinical studies producing contradictory results are available on the influence of fluid intake concerning the risk of UTI. One explanation for the inconsistency between the data might be the uncertainty about the exact amounts of fluid intake, which was mostly recorded in questionnaires. So far, there is no definitive evidence that the susceptibility for UTI is dependent on fluid intake. Nevertheless, adequate hydration is important and may improve the results of antimicrobial therapy in UTI. Results of experimental and clinical studies concerning urinary hydrodynamics are the basis for advice given by expert committees to patients with UTI to drink large volumes of fluid, void frequently, and completely empty the bladder. The combination of the behaviourally determined aspects of host defence and not simply increasing fluid intake is important in therapy and prophylaxis of UTI.
