Linear regression models of co-variables investigated for possible association with leukocyte telomere length (LTL).

A positive ß value indicates an association with longer LTL.

aSubjects with ethnicity Aboriginal, Black or Caucasian, N = 237/271 for HIV+/HEU, and N = 86/94 for HIV+.
bMaternal and paternal age at birth were known for N = 258/271 and N = 202/271 for HIV+/HEU and N = 83/94 and N = 66/94 for HIV+, respectively.
cIn a similar multivariate model where paternal age was included (data not shown), younger paternal age showed some association with shorter LTL (p = 0.06). The coefficients and p-values for the remaining explanatory variables were very similar between these two models.
dSince not on ART at visit and having a detectable pVL at visit are correlated, the variable with the lowest p value univariately was chosen for inclusion into the multivariable model. Models developed using AICc, PRESS, and SBC showed very similar results (supporting information).
