Background: Pregnancy Induced Hypertension (PIH) is a common burden during pregnancy usually associated with adverse maternal and paternal outcomes. The uric acid serum level was identified as an important biochemical marker which can predict preeclampsia, a type of PIH. This study was conducted to evaluate the effects of serum uric acid levels in association with blood pressure among pregnant women attending Ruhengeri Referral Hospital.
Methodology: A cross-sectional study was designed and 80 pregnant women in different gestation trimesters participated in the study. Data was collected from September to October 2018. Digital sphygmomanometer was used to test blood pressures for participants. Blood samples were collected in red top tubes and centrifuged to obtain serum for uric acid levels. Using Humastar 80, uric acid levels were measured for each participant. Data was analysed using Statistical Package for Social Sciences (SPSS) version 23.0. Bivariate correlation was used to analyse the relationship between uric acid levels and participants’ blood pressure.
Results: The median age was 27 in interquartile 23-31 ranging from 19 to 39 years. 58.75% of participants were in their 1st trimester, followed by 21.25% in the 2nd trimester and 20% in the 3rd trimester. The prevalence of hypertension was 11.3% (7.5% for stage 1 and 3.8% for stage 2). Hyperuricemia was found in 15% of the participants. The mean of uric acid level was 7.12 ± 1.86 mg/dl in the hypertensive group and 4.49 ± 1.22 mg/dl in the non-hypertensive group. The study revealed a strong positive correlation between uric acid levels and systolic /diastolic blood pressure.
Conclusion: High prevalence of hypertension among pregnant women was revealed. The association of hypertension and hyperuricemia was recorded with a strong correlation between blood pressures and serum uric acid levels. Examination of Uric acid levels among pregnant women should be routinely performed for early identification and management of hypertension.
