Abbreviations: BMI, body mass index (kg/m2); HbA1c, glycated hemoglobin; ICD-9-CM, International Classification of Diseases, Ninth Revision, Clinical Modification; PORTAL, Patient Outcomes Research to Advance Learning.
Data source: PORTAL weight cohort (7).
All values are percentages.
All between-group comparisons are significant at P < .001 (1-way analysis of variance) because of the large sample size.
Overweight defined as BMI of 23.0–27.4 for Asians and 25.0–29.9 for all other race/ethnicities.
Class 1 obesity defined as BMI of 27.5–34.9 for Asians and 30.0–34.9 for all other race/ethnicities.
Defined as systolic value of ≥130 mm Hg or diastolic value of >85 mm Hg or ICD-9-CM code from 401.0 to 405.9.
Defined as ≥150 mg/dL or an ICD-9-CM code of 272.1.
Defined as <40 mg/dL for men and <50 mg/dL for women or an ICD-9-CM code of 272.5.
Defined as HbA1c value of 5.7%–6.4% or a fasting glucose value of 100–125 mg/dL or an ICD-9-CM code of 790.2x). To be included in the data set, the electronic health record for an individual was required to have a value for either a fasting glucose test (84.7% of the total) or an HbA1c test (40.4%).
