Birth Outcomes and Prenatal PAH Exposure in a Nairobi Pregnancy Cohort

Allison R. Sherris published a dataset on figshare containing birth outcome data from a prospective cohort study in Nairobi, Kenya. The dataset includes information from 353 mother-infant pairs, with measurements of third-trimester urinary PAH metabolites and infant birth weight and gestational age. The data was last updated on 2026-05-13.

Use Cases

• Analyze associations between specific urinary PAH metabolites and gestational age based on the measured OH-PAH concentrations.
• Investigate potential sex-specific differences in environmental exposure effects based on the sex-stratified analysis mentioned.
• Study the role of household fuel and outdoor combustion as co-exposures in modifying birth outcome associations.
• Explore mixture effects of multiple PAH metabolites on birth outcomes using the Weighted Quantile Sum regression method described.

Strengths

• Dataset is based on a prospective cohort of 353 mother-infant pairs, providing a defined study population.
• All OH-PAH metabolites were detected in urine samples from over 99% of mothers, indicating high biomarker detection rates.
• Data includes computed BW-for-GA z-scores, offering a standardized measure of fetal growth.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 9.5 KB, indicating limited scope and feature set.
