  1. 1Q1, Q3 = Quartile 1, Quartile 3 (25th percentile, 75th percentile).
  2. 2The unit for relative telomere length is the T/S ratio. Telomere length was measured by quantitative PCR (qPCR), a method that determines relative telomere length by measuring the factor by which each DNA sample differs from a reference DNA sample in its ratio of telomere repeat copy number (T) to single-copy gene copy number (S).

  4. The enrollment characteristics included in this table were selected to provide context for our study population and to help frame our results. The table is not intended to summarize all covariates, but rather to highlight factors we consider most relevant to TL. Specifically, we focused on variables that are known to be associated with child telomere length, such as growth23.
