Adverse Perinatal Outcomes Among Grand Multiparous and Low Multiparous Women and Its Associated Factors in North Shewa Zone Public Hospitals: The Role of Parity

BACKGROUND: Adverse perinatal outcomes are the major cause of neonatal morbidity, mortality, and long-term physical and psychological consequences. Contradicting evidence across studies was reported about the impact of grand multiparity on adverse perinatal outcomes. Older literature reported increased incidence of perinatal complications in grand multiparas, but, recent reports failed to support this finding. In addition, there is a paucity of comparative studies on perinatal outcomes. Thus, the study aimed to compare the perinatal outcomes in grand multiparous (GM) and low multiparous (LM) women who give birth in North Shewa Zone Public Hospitals, Ethiopia, 2021. METHODS: A comparative cross-sectional study was done among 540 (180 GM and 360 LM) women from January 1 to March 30, 2021. The data were collected using a structured and pre-tested questionnaire through interviews and reviewing patient charts. SPSS version 25 was used for data analysis. The data were entered using Epi-Data version 4.6. The Hosmer–Lemeshow goodness-of-fit was applied to test for model fitness. The statistical significance level was declared at a p-value of ≤0.05. RESULTS: In this study, the prevalence of adverse perinatal outcomes was 14.1% (95% CI: 10.9–17.2). Stillbirth/IUFD (33.3%) and low APGAR score (60%) were frequently occurred complications in grand multiparas. Nevertheless, meconium aspiration (26%), admission to NICU (65.2%), macrosomia (61%), and prematurity (52.2%) were higher in low multiparous women. Age above 35 years (AOR (CI) = 2.61 (1.23–5.53)), rural residence (AOR (CI) = 8.31 (3.05–22.6)), being a government employee (AOR (CI) = 0.19 (0.05–0.69)), lack of antenatal care (AOR (CI) = 9.76 (3.03–31.5)), and previous pregnancy complications (AOR (CI) = 3.10 (1.63–5.90)) were significant predictors of adverse perinatal outcomes. However, parity did not show a statistically significant association with perinatal outcomes. CONCLUSION: Maternal age, residence, occupation, lack of antenatal care, and previous pregnancy complications were significant associates of perinatal outcome. There was no statistically significant difference in perinatal outcome between GM and LM women. Socio-economic development, good antenatal care, and early identification and treatment of complications are needed regardless of parity.
