  1. aHandgrip strength was measured at 12 years of age by using the digital handgrip meter with the most powerful posture. We calculated the average value for both hands.
  2. bThought problems were measured using the subscale of the child behavior checklist (CBCL) completed by the parents.
  3. cUrinary pentosidine levels were determined by a high-performance liquid chromatography assay.
  4. SD standard deviation.
