Associations of Leukocyte Telomere Length With Aerobic Fitness in Adults Aged 31 Years From Northern Finland Birth Cohort 1966 (n = 4,952), 1966–1997

Model	βa	95% CI	P Value
Model 1b	−0.7	−1.2, −0.2	0.004
Model 2c	−0.5	−1.0, −0.1	0.03
Model 3d	−0.5	−1.0, −0.01	0.05
Model 4e	−0.5	−1.0, −0.1	0.03

Abbreviations: CI, confidence interval; LTL, leukocyte telomere length.

^a Beta coefficients represent the average difference in heart rate (beats/minute) per 1-standard-deviation increase in mean relative LTL (lower heart rates indicating higher aerobic fitness).

^b Model 1—adjusted for age, sex, and LTL measurement batch.

^c Model 2—adjusted for model 1 variables plus body mass index, socioeconomic position, diet quality, smoking status, and alcohol consumption.

^d Model 3—adjusted for model 2 variables plus C-reactive protein.

^e Model 4—adjusted for model 2 variables plus physical activity.
