LS means of leukocyte telomere length <i>z</i> scores by numbers of low-risk lifestyle practices.

<p>Least-square means were adjusted for the same set of covariates for model 1 in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0038374#pone-0038374-t002" target="_blank">Table 2</a>. Low-risk group for each lifestyle factor was defined as non-current smoking, moderate alcohol use (1 drink/week to <2 drinks/day), a healthy body weight (18.5 kg/m²≤BMI<25.0 kg/m²), exercising at moderate to vigorous intensity (≥150 minutes/week), or AHEI diet score in top two quartiles.
