  1. aEstimated using sampling weights from National Health and Nutrition Examination Survey (NHANES)
  2. b Allostatic load total score was calculated as sum total of components based on high-risk thresholds: albumin, BMI, creatinine clearance, diastolic blood pressure, glycated hemoglobin, systolic blood pressure, total cholesterol, triglycerides. Score ranges from 0 to 8
  3. cPresented as weighted mean (standard error) for continuous variables
  4. dHigh allostatic load defined as total allostatic load score greater than or equal to 4
  5. ePresented as weighted column proportion (standard error)
  6. fDefined as self-reported response to ever being diagnosed by a doctor or health professional of any cancer or malignancy
