Abstract
Background
Urinary tract infection is the single most common bacterial infection of mankind.
Objective
To assess the risk factors and prevalence of Urinary tract infection among pregnant women attending antenatal care at Wachemo University Comprehensive Specialized Hospital, Central Ethiopia, 2023.
Methods
An institutional-based cross-sectional study design was conducted from 2 October to 29 December 2023. The total sample size was 405 and a systematic random sampling technique was used. Data were entered using the Epi-data 3.1 version and exported to SPSS 25 for analysis. Multicollinearity was checked. The goodness of fit test was done using the Hosmer-Lemeshow goodness of fit test. Binary logistic regression analysis was done, and variables with a p-value of <0.25 in the bivariable analysis were taken into the multivariable analysis. Statistical significance was declared at a p-value of <0.05 with an adjusted odds ratio and 95% confidence interval.
Result
The prevalence of urinary tract infection was 40.7% with 95%CI [36.5–45.2]. Rural resident [AOR: 2.32, 95% CI: 1.36–3.96], educational status of husband no formal education [AOR: 3.38, 95% CI: 1.24–9.21], educational status of husband primary level [AOR: 2.94, 95% CI: 1.06–8.18], having vaginal bleeding [AOR: 3.89, 95%CI: 1.78–8.47], having female genital mutation [AOR: 2.98, 95%CI: 1.83–4.84], itchiness around genitalia [AOR: 3.82, 95%CI: 1.14–12.82], and using water for cleaning after defecation [AOR: 0.46, 95%CI: 0.22–0.97] were significantly associated.
Conclusion
Four in ten pregnant women attending antenatal care had urinary tract infections. Residence, educational status of the husband, vaginal bleeding, female genital mutation, itchiness around genitalia, and mode of cleaning after defecation were significantly associated. Therefore, creating awareness for rural women, improving the educational status of husbands`, treatment of vaginal bleeding, avoiding female genital mutation, screening and treating itchiness around genitalia, and using water for cleaning after defecation might reduce the burden.
Introduction
Urinary tract infection (UTI) is the single most common bacterial infection of mankind caused by the presence and growth of microorganisms in any part of the urinary tract (Demilie et al., 2012; Emiru et al., 2013; Ilusanya et al., 2018). UTI affects all age groups, but women are more susceptible than men due to the short urethra, lack of prostatic discharge, pregnancy, and easy contamination of the urinary tract with fecal flora (Al-Haddad, 2015; Hala et al., 2017).
Literature shows that UTI particularly during pregnancy causes serious obstetric complications, including poor maternal and perinatal outcomes such as intrauterine growth restriction, preeclampsia, cesarean section, and preterm birth (Al-Haddad, 2015; Tadesse et al., 2014). UTI is a major cause of morbidity and mortality in pregnant women in sub-Saharan Africa. About 30% of women with untreated asymptomatic bacteriuria during pregnancy develop pyelonephritis, which can result in the delivery of low birth weight or preterm infants (Emiru et al., 2013; Tadesse et al., 2014).
There are studies done in Ethiopia previously (Assefa et al., 2008; Demilie et al., 2012; Obied & Abo Gad, 2017; Tadesse et al., 2014), however, these studies are done before 10 years. Even though, the system of health delivery, the attitude of the mothers toward seeking treatment, the lifestyle, and living environment have changed today. There is little data that states the current UTI status among pregnant women (Gebretensaie et al., 2023). As a result, the authors initiated to come with recent evidence of Urinary tract infection among pregnant women attending antenatal care at Wachemo University Comprehensive Specialized Hospital, Central Ethiopia.
Methods and Materials
Study Area and Period
The study was conducted at Wachemo University Comprehensive Specialized Hospital (WCUCSH). It is a teaching hospital of Wachemo University found in Hosanna town, Central regional state of Ethiopia. Hosanna town is the capital of Central Ethiopia Regional State. It is located 232 km from Addis Ababa (the capital city of Ethiopia). The hospital provides multidisciplinary services including outpatient department, emergency department, inpatient, Maternal and child health, laboratory, pharmacy, optometry, psychiatric clinics, orthopedic, and oncology services. The hospital has a total of 561 workers and of them, 409 are health professionals. The antenatal care unit has four rooms in which midwives, general practitioners, obstetricians, and gynecologists give antenatal care to pregnant women. The study was conducted from 2 October to 29 December 2023.
Eligibility Criteria
All pregnant women who visited antenatal care follow-up in WCUCSH at the time of data collection were included. However, pregnant women aged less than 18 years and critically ill were excluded from the study.
Sampling Size Determination
The sample size was determined using a single population formula. The assumptions of a 95% confidence interval, 5% margin of error, and a proportion of 39.8% taken from a previous study are as follows:
Sampling Procedure
The preceding three months’ report of ANC clinic was identified and it was 864. Then, the women were selected by using a systematic random sampling technique, considering a constant value of 2, which was obtained by dividing the total population by the total sample size (864/405). The first woman was determined by a lottery method and every second woman was interviewed.

Operational Definition
Data Collection Tool and Procedures
The tool was prepared in English and was structured questionnaires from related literature (Emiru et al., 2013; Tadesse et al., 2014). Data was collected through face-to-face interviews with mothers at the ANC clinic. The data was collected by three graduated Bachelor's degree midwives and supervised by an epidemiologist and a microbiologist.
Data Quality Control
The questionnaire was translated to Amharic (the official language of Ethiopia) before data collection, and back to English after data collection to ensure consistency by language expertise. A Pre-test was done on 5% of the total sample size at Doyogena Primary Hospital and necessary modification was performed based on the pre-test. Data collectors and the supervisor were trained for one day on the objectives of the study, how to select study participants, how to keep the collection format, and data quality management. The supervisors conducted daily follow-ups during the whole period of data collection. Every day, after data collection, each questionnaire was reviewed and checked for completeness by the investigator. The necessary feedback was given to the data collectors the next day.
Statistical Analysis
Data were entered by using Epi data version 3.1 and exported to SPSS version 25 software for analysis. Descriptive findings were presented by frequency tables, graphs, and percentages. Multi-collinearity was checked by considering tolerance and variance inflation factors. The goodness of fit test was done using the Hosmer-Lemeshow model goodness fit test. Bivariable analysis was done and variables with a p-value <0.25 were taken to multivariable logistic regression analysis. Adjusted odds ratio with a 95% confidence interval was considered and statistical significance was declared at p-value less than 0.05.

Factors Associated with Urinary Tract Infection Among Pregnant Women
In bivariable logistic regression analysis, residence, educational status of the husband, vaginal bleeding in current pregnancy, female genital mutation, history of urinary tract infection, burning sensation in current pregnancy, itching around genitalia, abdominal pain in current pregnancy and mode of cleaning after defecation were significantly associated with urinary tract infection among pregnant women attending antenatal care. Whereas in multivariable logistic regression analysis, residence [AOR: 2.32, 95% CI: 1.36–3.96], educational status of husband no formal education [AOR: 3.38, 95% CI: 1.24–9.21], educational status of husband primary level [AOR: 2.94, 95% CI: 1.06–8.18], vaginal bleeding in current pregnancy [AOR: 3.89, 95%CI: 1.78–8.47], female genital mutation [AOR: 2.98, 95%CI: 1.83–4.84], itchiness around genitalia [AOR: 3.82, 95%CI: 1.14–12.82], and mode of cleaning after defecation [AOR: 0.46, 95%CI: 0.22–0.97] were significantly associated with urinary tract infection among pregnant women attending antenatal care. (Table 4).

Discussion
The magnitude of urinary tract infection among pregnant women attending antenatal care was 40.7% with 95%CI [36.5–45.2]. It was consistent with studies conducted in Ghana 39.8%, Tanzania 41.0% (Mlugu et al., 2023), and 42.7% (Adabara et al., 2012). However, it was higher than studies conducted in various parts of Ethiopia were 9.5%-15.5% (Assefa et al., 2008; Demilie et al., 2012; Gebretensaie et al., 2023; Obied & Abo Gad, 2017; Tadesse et al., 2014), and study from Ghana was 17.1% (Adjato et al., 2019). In addition, it was higher than studies reported Kenya 15.7% (Onyango et al., 2018), Tanzania 16.8% (Kaduma et al., 2019), Cameroon 23.5% (Egbe et al., 2020), Iran 13.1% (Farazi and Jabbariasl, 2016), and India (20.1%–28.0%) (Ranjan et al., 2017; Takre et al., 2015). In contrast, it was lower than studies done in Nigeria (Adabara et al., 2012), and Saudi Arabia. The possible explanation for this variation might be due to variation within a country, across countries, and geographical areas, respectively, which can be attributed to factors such as varied personal hygiene practices, attitudes around UTIs, sexual behavior, limited healthcare infrastructure, and diagnostic tools. The within-country variation among Ethiopian studies might be related to the time differences, sexual behavior, and improved diagnostic tools in the current healthcare system.
In this study, residence was significantly associated with urinary tract infections among pregnant women attending antenatal care. Pregnant women whose residences were rural were 2.32 times more likely to have urinary tract infections compared to pregnant women whose residences were urban. In the Ethiopian setting, there is a limitation of infrastructures such as; educational coverage, toileting, health coverage, and clean water supply in rural areas. The limitation of these infrastructures especially, having poor knowledge about infection prevention, exposes the woman to UTI.
This study revealed that the educational status of husbands` was found to be significantly associated with urinary tract infections among pregnant women attending antenatal care. Pregnant women whose husbands had no formal education were 3.38 times more likely to have urinary tract infections compared to pregnant women whose husbands were educated above the secondary level. Similarly, pregnant women whose husbands attended the primary level were 2.94 times more likely to have urinary tract infections compared to pregnant women whose husbands were educated above the secondary level. This could be explained from different directions. Those husbands who had better educational status gave information to their wives about the UTI itself and the mechanisms of prevention. Similarly, educated husbands live in environments where there is better infrastructure exposure to social media, and with educated neighbors. Additionally, those pregnant women whose husbands were educated above the secondary level could have better socioeconomic status, live in urban settings, and manage lifestyles. Due to these possible reasons, pregnant women whose husbands lack educational access were prone to urinary tract infections.
Vaginal bleeding in current pregnancy was significantly associated with urinary tract infection among pregnant women attending antenatal care in this study. Pregnant women who had vaginal bleeding in their current pregnancy were 3.89 times more likely to have urinary tract infections compared to pregnant women who did not have vaginal bleeding in their current pregnancy. This might be related to the nature of bleeding that predisposes the mother to anemia. In another study anemia is a significant factor for UTI among pregnant women (Emiru et al., 2013). The high probability of developing UTI among anemic pregnant women may be related to immunity. In addition, bleeding from the vagina gives a chance for the microorganisms to ascend via the urethra.
In this study, female genital mutation was significantly associated with urinary tract infection among pregnant women attending antenatal care. Genitally mutilated pregnant women were 2.98 times more likely to have urinary tract infections compared to pregnant women who are not genitally mutilated. Sadly, female genital mutilation is common in the current study area and the mutilation is carried out by traditional means at various childhood ages. The type of mutilation practiced in the area is cutting the clitoris. This association might be due to the absence of a clitoris that makes microorganisms easily ascend through the urethra.
In this study, itchiness around genitalia was significantly associated with urinary tract infections among pregnant women attending antenatal care. Pregnant women who had itchiness around genitalia were 3.82 times more likely to have urinary tract infections compared to pregnant women who did not have itchiness around genitalia. This was stated in another study as pregnant women who had a previous history of UTI were 3.397 times more likely to be infected than the compared group (Emiru et al., 2013). This might be due to continued exposure to the causing microorganisms. In addition, itching around the genitalia might be the clinical manifestation of the infection.
Mode of cleaning after defecation was significantly associated with urinary tract infection among pregnant women attending antenatal care. Pregnant women who clean with water after defecation were 54% less likely to have urinary tract infections compared to pregnant women who clean with soft tissue. This is due to that washing the anus and genitalia after defecation removes fecal contents from the anus. In contrast, using tissue paper does not remove all fecal contents which give the best opportunity for microorganisms to grow. Then, due to the anatomic nearness of the anus to the urethra, the microorganism freely spread to the urethra.
Conclusion
Four in ten pregnant women attending antenatal care had a urinary tract infection. Residence, educational status of the husband, vaginal bleeding in the current pregnancy, female genital mutation, itchiness around genitalia, and mode of cleaning after defecation were significantly associated with urinary tract infection among pregnant women attending antenatal care. Therefore, creating awareness about urinary tract infections for rural women, improving the educational status of husbands’, early and effective treatment of vaginal bleeding during pregnancy, avoiding female genital mutation, screening and treating itching around the genitalia, and using water for cleaning after defecation might reduce the burden of urinary tract infection among pregnant women.
