Abstract

Aims/hypothesis We determined the effects of 6 years of lifestyle intervention in persons with impaired glucose tolerance (IGT) on the development of retinopathy, nephropathy and neuropathy over a 20 year period.Methods In 1986, 577 adults with IGT from 33 clinics in Da Qing, China were randomly assigned by clinic to a control group or one of three lifestyle intervention groups (diet, exercise, and diet plus exercise). Active intervention was carried out from 1986 to 1992. In 2006 we conducted a 20 year follow-up study of the original participants to compare the incidence of microvascular complications in the combined intervention group vs the control group.Results Follow-up information was obtained on 542 (94%) of the 577 original participants. The cumulative incidence of severe retinopathy was 9.2% in the combined intervention group and 16.2% in the control group (p = 0.03, log-rank test). After adjusting for clinic and age, the incidence of severe retinopathy was 47% lower in the intervention group than the control group (hazard rate ratio 0.53, 95% CI 0.29-0.99, p = 0.048). No significant differences were found in the incidence of severe nephropathy (hazard rate ratio 1.05, 95% CI 0.16-7.05, intervention vs control, p = 0.96) or in the prevalence of neuropathy (8.6% vs 9.1%, p = 0.89) among the 20 year survivors.Conclusions/interpretation Lifestyle intervention for 6 years in IGT was associated with a 47% reduction in the incidence of severe, vision-threatening retinopathy over a 20 year interval, primarily due to the reduced incidence of diabetes in the intervention group. However, similar benefits were not seen for nephropathy or neuropathy.

  • At 20 years in the DaQing Diabetes Prevention Study, lifestyle intervention cut diabetes risk by 43% and postponed onset by an average of 3.6 years.

  • At 20 years in the DaQing Study, lifestyle intervention was tied to a nearly 50% lower relative risk of new severe retinopathy.

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.
