Abstract

Diabet. Med. 27, 398–404 (2010) Aims Time trends in overweight and obesity in the general population have been well documented; however, temporal patterns in Type 1 diabetes (T1DM) have not been thoroughly investigated. We therefore assessed temporal patterns in overweight and obesity and predictors of weight change in 589 individuals from the Pittsburgh Epidemiology of Diabetes Complications Study, a cohort of childhood‐onset T1DM. Methods Participants were first seen in 1986–1988, when mean age and diabetes duration were 29 and 20 years, respectively, and biennially thereafter for 18 years. Overweight was defined as 25.0 ≤ body mass index (BMI) < 30.0 kg/m 2. Obesity was defined as BMI ≥ 30.0 kg/m 2. Results At baseline, the prevalence of overweight and obesity were 28.6% and 3.4%, respectively. After 18 years’ follow‐up, the prevalence of overweight increased by 47% while the prevalence of obesity increased sevenfold. Seven per cent were on intensive insulin therapy (≥ 3 insulin injections per day or on insulin pump) at baseline; by 2004–2007, this was 82%. Predictors of weight change were a higher baseline HbA 1c, symptomatic autonomic neuropathy (inversely), overt nephropathy (inversely), and going onto intensive insulin therapy during follow‐up. Conclusions These data demonstrate dramatic weight gain in T1DM and underscore the complexity of weight change in this disease.

  • Currently, over 50% of people with type 1 diabetes have overweight or obesity.

    “Currently, over 50% of people with type 1 diabetes have overweight or obesity (180 -182).”

    From Nutrition Therapy for Adults With Diabetes or Prediabetes: A Consensus Report (2019) · cites this paper as [181]

    The Results and Discussion (page unavailable) report that 64.6% of the study’s type 1 diabetes cohort had overweight or obesity in 2004–2007, supporting the over-50% figure. The paper does not establish that this prevalence applies to all people with type 1 diabetes or to a later 'current' period; it also notes possible survival bias in the cohort. (LLM, conf=0.85)

  • Currently, over 50% of people with type 1 diabetes have overweight or obesity.

    “Currently, over 50% of people with type 1 diabetes have overweight or obesity (180 -182).”

    From Nutrition Therapy for Adults With Diabetes or Prediabetes: A Consensus Report (2019) · cites this paper as [182]

    The Results report that, in 2004–2007, 42.0% of the study cohort was overweight and 22.7% was obese—64.7% combined. This supports the over-50% figure for that cohort, but not an unqualified claim about all people with type 1 diabetes currently; the Discussion also describes the remaining cohort as substantially survival-biased. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Obesity prevalence among people with type 1 diabetes has been significantly increasing.

    “Obesity prevalence among people with type 1 diabetes has been signi fi cantly increasing (180 -182).”

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.
