Abstract
OBJECTIVE: To determine the association between oil pollution and miscarriage, stillbirth, and infant death in the Niger Delta region of Nigeria. METHODS: A retrospective cohort study was undertaken of pregnant women (aged 18-45 years) who attended selected health facilities in regions with high and low exposure to oil pollution from May 14, 2018, to September 27, 2018. A multistage sampling technique was used to randomly select a representative of women with high and low exposure to oil pollution. An interviewer-administered questionnaire was used for data collection. Bivariate and multivariable logistic regression analyses were employed to adjust for confounding factors of miscarriage, stillbirth, and infant death. RESULTS: In total, 1564 pregnant women were included in the study. Women with high exposure to oil pollution were more likely to experience stillbirth (odds ratio [OR] 1.806; 95% confidence interval [CI] 1.177-2.770) and infant death (OR 2.162; 95% CI 1.409-3.317). However, after adjusting for potential confounders, only infant death was associated with high exposure (adjusted OR 1.843; 95% CI 1.146-2.962). No association was found between miscarriage and high exposure to oil pollution. CONCLUSION: Women with high exposure to oil pollution are at higher risk of infant death.
