Background: The World Health Organization encourages countries to improve birth outcomes to reduce rates of neonatal mortality and morbidity. Purpose: This study was designed to examine the effect of environmental crude oil pollution on newborn birth outcomes in Rivers State, Nigeria. Methods: A retrospective cohort design was used to examine the effects of exposure to oil pollution on birth outcomes using facility-based records. K-Dere (an oil-polluted community) served as the exposure group, whereas birth records from Iriebe served as the comparison group. A sample size of 338 systematically selected birth records was examined (169 records for each arm of the study). A data extraction sheet was used for data collection. Data were analyzed using descriptive and inferential statistics at p ＜ .05. Results: The risk of preterm birth was significantly higher in the exposed group (16% vs. 7.7%, relative risk = 2.08, 95% CI [1.11, 3.89], p = .018). At 6 weeks after birth, newborns in the exposed group weighed significantly less (4.64 ± 0.82 vs. 4.85 ± 0.92 kg, p = .032) and reported significantly higher incidence of morbidity compared with the newborns in the comparison group (relative risk = 3.03, 95% CI [2.20, 4.19], p ＜ .001). Conclusions: The oil-polluted area examined in this study was found to have a higher risk of preterm birth, a slower rate of newborn growth, and a higher rate of newborn morbidity than the non-oil-polluted area at 6 weeks after birth. Stakeholders should sustain efforts to remediate the environment in polluted regions and prevent oil pollution. Future research should investigate the mechanisms of the observed toxicological effects and the targeted protection of vulnerable groups in oil-polluted communities. |
