Abstract

OBJECTIVE—Systemic oxidative stress causes insulin resistance in rodents. We tested the hypothesis that oxidative stress and insulin resistance are associated in humans. RESEARCH DESIGN AND METHODS—We used cross-sectional data from 2,002 nondiabetic subjects of the community-based Framingham Offspring Study. We measured insulin resistance with the homeostasis model and defined categorical insulin resistance as homeostasis model assessment of insulin resistance (HOMA-IR) >75th percentile. We measured oxidative stress using the ratio of urine 8-epi-prostaglandin F2α (8-epi-PGF2α) to creatinine and used age- and sex-adjusted regression models to test the association of oxidative stress with insulin resistance in individuals without diabetes and among subgroups at elevated risk of diabetes. RESULTS—Across 8-epi-PGF2α/creatinine tertiles, the prevalence of insulin resistance increased (18.0, 27.5, and 29.4% for the first, second, and third tertiles, respectively; P < 0.0001), as did mean levels of HOMA-IR (3.28, 3.83, and 4.06 units; P < 0.0001). The insulin resistance–oxidative stress association was attenuated by additional adjustment for BMI (P = 0.06 across tertiles for insulin resistance prevalence; P = 0.004 for mean HOMA-IR). Twenty-six percent of participants were obese (BMI ≥30 kg/m2), 39% had metabolic syndrome (according to the Adult Treatment Panel III definition), and 37% had impaired fasting glucose (IFG) (fasting glucose 5.6–6.9 mmol/l). Among 528 obese participants, respectively, insulin resistance prevalence was 41.3, 60.6, and 54.2% across 8-epi-PGF2α/creatinine tertiles (P = 0.005); among 781 subjects with metabolic syndrome, insulin resistance prevalence was 41.3, 56.7, and 51.7% (P = 0.0025); and among 749 subjects with IFG, insulin resistance prevalence was 39.6, 47.2, and 51.6% (P = 0.04). CONCLUSIONS—Systemic oxidative stress is associated with insulin resistance in individuals at average or elevated risk of diabetes even after accounting for BMI.

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.
