Abstract

We examined body mass index (BMI) as a screening tool for gestational diabetes (GDM) and its sensitivity among different racial/ethnic groups. In a retrospective cohort study of 24,324 pregnant women at University of California, San Francisco, BMI was explored as a screening tool for GDM and was stratified by race/ethnicity. Sensitivity and specificity were examined using chi-square test and receiver-operator characteristic curves. BMI of ≥25.0 kg/m (2) as a screening threshold identified GDM in >76% of African-Americans, 58% of Latinas, and 46% of Caucasians, but only 25% of Asians ( P < 0.001). Controlling for confounders and comparing to a BMI of ≤25, African-Americans had the greatest increased risk of GDM (adjusted odds ratio [AOR] 5.1, 95% confidence interval [CI]: 3.0 to 8.5), followed by Caucasians (AOR 3.6, 95% CI: 2.7 to 4.8), Latinas (AOR 2.7, 95% CI: 1.9 to 3.8), and Asians (AOR 2.3, 95% CI: 1.8 to 3.0). BMI's screening characteristics to predict GDM varied by race/ethnicity. BMI can be used to counsel regarding the risk of developing GDM, but alone it is not a good screening tool.

  • The prevalence of gestational diabetes mellitus was highest among Asian women with BMI ≥30 kg/m2 (13.78%), followed by BMI ≥25 kg/m2 (10.22%) and BMI ≥20 kg/m2 (6.09%).

    “prevalence of GDM was highest among Asian women with BMI ≥ 30 kg/m2 (13.78%), followed by BMI ≥ 25 kg/m2 (10.22%) and BMI ≥ 20 kg/m2 (6.09%).”

    From Prevalence and risk factors of gestational diabetes mellitus in Asia: a systematic review and meta-analysis (2018) · cites this paper as [170]

    The Results (page unavailable) say Asian women had the highest GDM rate within each BMI category, and the Discussion says GDM prevalence increased with prepregnancy BMI. Our copy does not give the claimed 13.78%, 10.22%, or 6.09% figures. It also describes separate BMI categories rather than the cumulative ≥30, ≥25, and ≥20 groups stated in the claim. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • A BMI ≥25 kg/m2 has a lower sensitivity (24.9%) but a good specificity (88.7%) compared with a BMI ≥21 kg/m2 cut-off, which has a higher sensitivity (68.4%) but a lower specificity (53.6%).

    “A BMI ≥ 25 kg/m2 has a lower sensitivity (24.9%) but a good specificity (88.7%) in comparison to using a cut-off level of BMI ≥ 21 kg/m2 which has a higher sensitivity of 68.4% but a lower specificity of 53.6% [170].”

    From Prevalence and risk factors of gestational diabetes mellitus in Asia: a systematic review and meta-analysis (2018) · cites this paper as [170]

    The Results report all four sensitivity and specificity figures for Asian women with gestational diabetes. The citing sentence omits that population qualifier, making the figures appear applicable to pregnant women generally, whereas the paper shows that screening performance varies substantially by race/ethnicity. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • The prevalence of gestational diabetes mellitus increases with increasing pre-pregnancy BMI.

    “Prevalence of GDM is also increased with increasing pre-pregnancy BMI [170].”

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.
