Abstract

Peripheral neuropathy is reported in obesity even in the absence of hyperglycaemia. To compare the prevalence and characterise the phenotype of peripheral neuropathy in people living with obesity (OB) and long-duration type 1 diabetes (T1D). We performed a prospective cross-sectional study of 130 participants including healthy volunteers (HV) ( n = 28), people with T1D ( n = 51), and OB (BMI 30–50 kg/m 2 ) ( n = 51). Participants underwent assessment of neuropathic symptoms (Neuropathy Symptom Profile, NSP), neurological deficits (Neuropathy Disability Score, NDS), vibration perception threshold (VPT) and evaluation of sural nerve conduction velocity and amplitude. Peripheral neuropathy was present in 43.1% of people with T1D (age 49.9 ± 12.9 years; duration of diabetes 23.4 ± 13.5 years) and 33.3% of OB (age 48.2 ± 10.8 years). VPT for high risk of neuropathic foot ulceration (VPT ≥ 25 V) was present in 31.4% of T1D and 19.6% of OB. Participants living with OB were heavier (BMI 42.9 ± 3.5 kg/m 2 ) and had greater centripetal adiposity with an increased body fat percentage (FM%) ( P < 0.001) and waist circumference (WC) ( P < 0.001) compared to T1D. The OB group had a higher NDS ( P < 0.001), VAS for pain ( P < 0.001), NSP ( P < 0.001), VPT ( P < 0.001) and reduced sural nerve conduction velocity ( P < 0.001) and amplitude ( P < 0.001) compared to HV, but these parameters were comparable in T1D. VPT was positively associated with increased WC ( P = 0.011), FM% ( P = 0.001) and HbA1c ( P < 0.001) after adjusting for age ( R 2 = 0.547). Subgroup analysis of respiratory quotient (RQ) measured in the OB group did not correlate with VPT ( P = 0.788), nerve conduction velocity ( P = 0.743) or amplitude ( P = 0.677). The characteristics of peripheral neuropathy were comparable between normoglycaemic people living with obesity and people with long-duration T1D, suggesting that metabolic factors linked to obesity play a pivotal role in the development of peripheral neuropathy. Further studies are needed to investigate the mechanistic link between visceral adiposity and neuropathy.

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.
