A Case-control Study On The Risk Factors Of Childbearing Period Women With Urinary Tract Infection

Objective:To investigate the risk factors of living habits associated with urinary tract infection in childbearing period women. Method:Non paired case-control study method was employed, the study group(n=140) was composed of childbearing period women with urinary tract infection treated at Beijing Xuanwu Hospital, between December2010and June2013, the control group (n=140) was composed of the healthy childbearing period women who were coming for health check up. The questionnaires were used to collect demographic data and data of living habits. Single factors and multi factors non conditional logistic regression analysis was implemented by SPSS19.0software.Results:Two groups of objects were in general equilibrium. Single factor analysis revealed that wearing chemical fibber briefs, wiping direction after bowel movement, sedentary, withhold urine, the replacement of sanitary napkins less, the use of sanitary pads and changing sanitary less as well as frequent sexual behavior are risk factors for urinary tract infection. While often cleaning towel, changing underwear often, underwear drying method, washing hands before toilet, cleaning vulva during menstrual period, cleaning vulva before sex, urination immediately after sex are protective factors for urinary tract infection.Multi factor analysis revealed that the frequency of replacing underpants (OR=0.329,95%CI:0.154-0.702), wearing chemical fibber briefs (OR=3.204,95%CI:1.582-6.486), underwear drying method (OR=0.126,95%CI:0.040-0.395, OR=0.040,95%CI:0.010-0.160), sedentary (OR=4.029,95%CI:2.079-7.811),washing hands before urination (OR=0.207,95%CI:0.094-0.454) holding back urine behavior (OR=2.197,95%CI:1.162-4.156),the replacement of sanitary napkins less (OR=6.181,95%CI:2.332-16.383), changing sanitary less (OR=3.282,95%CI:1.884-5.718),clean vulva during menstrual period (OR=0.321,95%CI:0.176-0.587),vulva cleaning before sex (OR=0.273,95%CI:0.145-0.516) are significant factors associated with the incidence of urinary tract infection, among these, often cleaning towel, changing underwear often, underwear drying method, toilet washing hands before urination, clean vulva during menstrual period vulva cleaning before sex, urination immediately after sex are protective factors for urinary tract infection.Conclusions:There are risk factors in living habits associated with urinary tract infection in women of childbearing age, daily underwear change, no chemical fibber briefs, expose the underwear after washing to sunshine or ventilated area, avoid sedentary, hand wash before urination, no holding back urine behavior, increase the replacement of sanitary napkins and pad, clean vulva during menstrual period, vulva cleaning before sex are capable of lower down the risk of urinary tract infection.
