Table 1.

Association between telomere characteristics and potential confounders. Number (%) is shown; p-values were assessed with Pearson or Spearman rho correlation; n = 109 samples.

Potential Confounder	Association with Mean Telomere Length
Maternal age	r = 0.09 CI = −0.030, 0.078 p = 0.37
Gestation age	r = 0.15 CI = −0.100, 0.832 p = 0.12
Parity	r = 0.09 CI = −0.173, 0.479 p = 0.35
Smoking 14/109 (12.9%)	r = −0.00 CI = −0.765, 1.023 p = 0.776
Alcohol 8/109 (7.3%)	r = 0.11 CI = −0.421, 1.85 p = 0.214
BMI	r = −0.03 CI = −0.056, 0.093 p = 0.792
WIMD	r = 0.22 CI = 0.000, 0.001 p = 0.027

BMI = body mass index; WIMD = Welsh Index of multiple deprivation.
