Mosaic plots demonstrating the relationship between significant covariates and relative leukocyte telomere length (rLTL) (Quartile 1 (shortest rLTL) and Quartile 4 (longest rLTL)) analyzed using Fisher’s exact test. Height of bars represents proportion of participants in each category and their quartile of rLTL, the width of each bar is proportional to sample size. (A) For smoking history (n = 48), more participants that had never smoked had longer rLTL compared to former smokers (p = 0.01). (B) For income (n = 42), participants that had earned ≥$75,000 had the longest rLTL (p = 0.02). (C) Cardiovascular health measured by Life’s Simple 7 metric (n = 44) was associated with rLTL; more participants with “optimal” cardiovascular health had longer rLTL than those with “average” cardiovascular health (p = 0.02). (D) Physical activity was measured using the International Physical Activity Questionnaire (n = 38). More participants that were active and had longer rLTL than those who were inactive (p = 0.01).
