Perfluoroheptanoic acid (PFHpA) is a perfluoroalkyl substance (PFAS).1 Prenatal exposure to PFHpA is positively correlated with preterm birth, primarily in male infants. It is also positively correlated with fat mass, body mass index (BMI), and waist circumference in females but negatively associated with BMI, waist circumference, and weight-to-height ratio in males.2
