Abstract

Purpose Perfluoroalkyl substances (PFASs) are a class of manmade chemicals commonly used in consumer product manufacturing. Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) are two of the most highly studied PFASs. Both are present in the blood of the most Americans. PFASs are associated with intermediate cardiovascular disease (CVD) outcomes, but their relationship with obesity, a risk factor for intermediate and advanced CVD, remains largely unconfirmed. In this context, we aimed to explore the relationship between PFASs and both overweight/obesity and abdominal obesity among children. Methods We examine associations between PFOA and PFOS levels, and Body Mass Index (BMI) and waist circumference (WC) in a representative sample (N = 2473) of US children, aged 12-18 years from the Centers for Disease Control and Prevention's National Health and Nutrition Examination Survey 1999-2012. Overweight/obesity is defined as age-, sex-specific BMI z-score ≥ 85th percentile; abdominal obesity is defined as age-, sex-specific waist circumference ≥90th percentile. Results Associations between PFASs and anthropometric outcomes show a dose-response relationship overall. For overweight/obese BMI z-score, findings indicate OR = 1.42 and 95% CI: 0.85-2.38 for quartile 2 of PFOA exposure; OR = 2.22 (95% CI: 1.20-4.13) for quartile 3 of PFOA exposure; and OR = 2.73 (95% CI:1.10-6.74) for quartile 4 of PFOA exposure. Discussion Findings indicate an association between elevated…

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
