  1. BMI, body mass index; LDL, low-density lipoprotein; HDL, high-density lipoprotein; HOMA-IR, homeostasis model assessment of insulin resistance; PTH, parathyroid hormone; Normal range of PTH is 8–76 pg/mL. Data are expressed as the means ± standard error (SE), percentage (SE) or geometric means (95% confidence interval).
  2. Low educational status: subject with elementary to middle school.
  3. Low income: the lowest quartile.
