Multivariate-adjusted least-squares (LS) means of <i>z</i> score of leukocyte telomere length (LTL) and relative LTL difference by low vs. high risk groups for each modifiable risk factor in women.

*<p>Model 1 was adjusted for the same set of covariates in model 1, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0038374#pone-0038374-t002" target="_blank">Table 2</a>.</p>†<p>Based on model 1, these modifiable risk factors were mutually adjusted for, i.e., we mutually controlled for smoking status (never smoked, past smoker, or current smoker), body mass index (<18.5 kg/m², 18.5–24.9 kg/m², 25.0–29.9 kg/m², or ≥30 kg/m²), moderate to vigorous physical activity (≥150 minutes/week, 60–149 minutes/week, <60 minutes/week, or 0 minutes/week), AHEI diet score (in quartiles), and alcohol use (≥2 drinks/day, 1 drink/week to <2 drinks/day, <1 drink/week, or non-user).</p>‡<p>% Difference measures the change of standardized LTL for each category in proportion to the standardized LTL of the reference category for each factor after multivariate adjustment.</p>¶<p>AHEI diet score summarized intakes of <i>trans</i> fat, polyunsaturated to saturated fat ratio, ratio of chicken and fish to red meat, fruits, vegetables, soy, nuts, cereal fiber, and multivitamin use.
