Abstract

We investigated the association between specific types of physical activity and the risk of type 2 diabetes in a systematic review and meta-analysis of published studies. PubMed, Embase and Ovid databases were searched for prospective studies and randomized trials up to 2nd of March 2015. Summary relative risks (RRs) were calculated using a random effects model. Eighty-one studies were included. The summary RRs for high versus low activity were 0.65 (95 % CI 0.59-0.71, I(2) = 18 %, n = 14) for total physical activity, 0.74 (95 % CI 0.70-0.79, I(2) = 84 %, n = 55) for leisure-time activity, 0.61 (95 % CI 0.51-0.74, I(2) = 73 %, n = 8) for vigorous activity, 0.68 (95 % CI 0.52-0.90, I(2) = 93 %, n = 5) for moderate activity, 0.66 (95 % CI 0.47-0.94, I(2) = 47 %, n = 4) for low intensity activity, and 0.85 (95 % CI 0.79-0.91, I(2) = 0 %, n = 7) for walking. Inverse associations were also observed for increasing activity over time, resistance exercise, occupational activity and for cardiorespiratory fitness. Nonlinear relations were observed for leisure-time activity, vigorous activity, walking and resistance exercise (p nonlinearity < 0.0001 for all), with steeper reductions in type 2 diabetes risk at low activity levels than high activity levels. This meta-analysis provides strong evidence for an inverse association between physical activity and risk of type 2 diabetes, which may partly be mediated by reduced adiposity. All subtypes of physical activity appear to be beneficial. Reductions in risk are observed up to 5-7 h of leisure-time, vigorous or low intensity physical activity per week, but further reductions cannot be excluded beyond this range.

  • The meta-analysis included 20 articles (22 independent studies), comprising 40,485 pregnant women and 4402 gestational diabetes mellitus participants.

    “The initial search yielded 4368 relevant articles in the database. Following the elimination of 4348 ineligible articles, 20 articles were ultimately included (a total of 22 independent studies), which included 40,485 pregnant women and 4402 GDM participants [10, 14, 16–18, 28–42].”
  • Risk factors for type 2 diabetes include overweight and obesity, physical inactivity, age, family history, race and ethnicity, history of gestational diabetes, and presence of other conditions (eg, hypertension, dyslipidemia, cardiovascular disease).

  • Physical activity is an effective regimen to lower the risk of developing diabetes by improving β-cell function.

    “Several studies have demonstrated that physical activity is an effective regimen to lower the risk of developing diabetes by improving the β-cell function (172).”
  • Lack of physical activity is a risk factor for ASCVD such as CAD and cerebrovascular disease.

    “It is also a risk factor for ASCVD such as CAD and cerebrovascular disease577–587).”
  • Lack of physical activity is associated with increased body fat (obesity), dyslipidemia, metabolic syndrome, hypertension, diabetes/impaired glucose tolerance, vascular endothelial dysfunction, and decreased physical fitness.

    “Lack of physical activity is associated with increased body fat (obesity), dyslipidemia, metabolic syndrome, hypertension, diabetes/impaired glucose tolerance, vascular endothelial dysfunction, and decreased physical fitness.”

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.
