Predictors of Asymptomatic Bacteriuria among Obstetric Population in Ibadan

Abstract

Asymptomatic bacteriuria in pregnancy is the major risk factor for symptomatic urinary tract infection during pregnancy. Screening and identification of bacteriuria during pregnancy have been recommended.
The general objective of the study was to determine the pattern as well as possible predictors of asymptomatic bacteriuria at the University College Hospital, Ibadan. The study was a descriptive, cross sectional,
exploratory survey of the pattern of asymptomatic bacteriuria among all consecutive patients presenting for the first antenatal visit at the University College Hospital, Ibadan during the study period. The prevalence of asymptomatic bacteriuria was 10.7%. Although no statistically significant
association was found, the prevalence was higher among women aged between 26 - 35 years (11.5%) and those with only secondary education (14.6%). Other demographic parameters characterized by high rates of
bacteriuria were Christian women (12.7% compared to 4.3% among Muslims) and genotypes AS andAC (16.4% and 16.7% respectively). Low parity (para 1-2), 2 and 3 trimesters of pregnancy were the identified possible obstetric predictors of bacteriuria in pregnancy. Staphylococcus species constitute the predominant isolates in 3 trimester and among Muslim pregnant women.
Since no statistically significant predictors for bacteriuria in pregnancy were found, routine screening of all our pregnant women for this condition in 2 trimester is recommended.
