  1. Prevalence ratios for high allostatic load are estimated using modified Poisson regression with robust variance estimation and accounting for NHANES weighting. Confidence intervals estimated using delete-1 jackknife method accounting for complex statistical weighting, cluster, and strata
  2. aNumber of participants with high allostatic load per stratum (weighted stratum proportion with high allostatic load)
  3. bModel 1: Adjusted for age only
  4. cModel 2: Additionally adjusted for total number of pregnancies, age at menarche, and poverty to income ratio,
  5. dModel 3: Additionally adjusted for depressive disorder, smoker status, ever congestive heart failure, and ever heart attack
