It is the series pregnancy problem not precisely known and only available few research findings are inconsistent & not well established.
Objectives: The aim of this study is to assess the association between Stillbirth and hypertensive disorder and obstetric factors.
Methods: Facility based unmatched case-control study design was employed from January2018 to June2019, (287 cases and 574 controls) was selected using systematic random sampling methods. Double population proportions formula with 1:2 case to control ratio was used to calculate sample size with 95% confidence interval and 80% power. The data was collected from clinical records of mother’s a using data collecting checklist. Epi data version 184.108.40.206 was used for data entry, and analysis was done by SPSS version 21 statistical software. Descriptive analysis such as frequency, percentage and chi-square test were done. For the inferential analysis, a multivariable analysis was done. Statically significant was used at a p-value <0.05 both for the univarible and multivariable analysis.
Result: Women who had hypertensive disorder were 1.76 times at risk to have stillbirth than no hypertensive disorder (AOR: 1.76: 95%CI :( 1.06, 2.9). In addition, women who had first antenatal care at third trimester were 4 times at higher risk to have still birth than women, who had first antenatal care at first trimesters (AOR: 4, 95%CI: (1.54, 11). Women who had more than four children were 2.6 times at higher risk of having still birth compared with women one child (AOR: 2.6, 95%CI: (1.2, 5.7). Furthermore, the odds of having still birth was found to be higher in women, who had blood group O than blood group A (AOR: 1.7: 95%CI: (1.057, 2.8).
Conclusion: According to the findings of this study, we conclude that a hypertensive disorders and obstetric factors were risk factors for stillbirth. Therefore, it is significant to give special attention to women with hypertensive disorder and multipara women.
