  • Data are weighted mean (SD).

  • *T/S ratio is the relative amount of telomeric DNA (T) to the beta-globin single copy gene (S), calibrated to a plate reference genomic DNA sample.

  • Disadvantage Index, Socio-Economic Indexes for Areas Index of Relative Socioeconomic Disadvantage (national mean: 1000, SD 100), where higher scores represent less disadvantage); 

  • n, sample size number.
