Determinants of Adverse Pregnancy Outcomes among Women Attending Antenatal Care-Clinic in Public Health Facilities in Nyando Sub-County, Kenya

Abstract

Adverse pregnancy outcome (APO) refers to gestation results other than vaginal birth, which include premature birth, miscarriage and low birth weight which are main causes of maternal and neonatal illness and death. In Kenya, the maternal mortality ratio stands at 355 deaths per 100,000 live births. In Kisumu County maternal mortality rate stands at 495 per 100,000 live births per year and Nyando Sub-County has the second- worst record of adverse pregnancy outcomes. Therefore, the current the current study assessed the determinants of adverse pregnancy outcomes among women attending 4 selected public health facilities in Nyando Sub-County. In this multicenter hospital-based cross-sectional study, n=301 women who delivered at the 4 randomly selected hospitals Nyando Sub-County hospital and visited the ANC department at least twice were systematically randomly recruited from November 2022 to September 2023. Data was collected using pre-tested and structured questionnaire which consisted of sections of demographic and obstetric characteristics. Presence of at least one maternal complication was used to determine the presence of APO. SPSS version 27 was used for data analysis. Chi-square ( 2) was used to compare proportions based on pregnancy outcomes as normal and adverse. Association between socioeconomic status and APO, obstetric factors and APO as well as ANC visits and APO were determine using Binary logistic regression. Of the 301 participants, 96 (31.9%) had normal pregnancy outcome (NPO) while 205 (68.1%) had APO. Woman’s age, parity, marital status, family income and education were associated with APO p=0.001, p=0.001, p=0.001, p=0.001 and p=0.04 respectively. With regard to obstetric factors, women of between 16-35 years were less likely to develop APO [OR=0.410, 95% CI=0.260-0.670, p=0.001]. In terms of gestation period with 37 weeks as the reference group, women with 28-37 weeks of gestation are less likely to develop APO [OR=0.114, 95% CI=0.132- 0.497, p=0.001]. The study did not find any association with the number of ANC visits [OR=0.39 95% CI=0.36-1.26, p=0.314] however, women visiting ANC in the second trimester less likely to develop APO [OR=0.221, 95% CI=0.142-0.927, p=0.001]. Therefore, both sociodemographic and obstetric factor affect pregnancy outcome and early ANC visit is associated with better or normal pregnancy outcome.
