Serum and Dietary Folate and Vitamin B₁₂ Levels Account for Differences in Cellular Aging: Evidence Based on Telomere Findings in 5581 U.S. Adults

Table 2

Mean differences in telomere length (base pairs) between U.S. men and women ().

	Men	Women
	Telomere length
Model 1			4.6	0.0402
Model 2			6.8	0.0146

SE: standard error. Means have been adjusted for the covariates, as defined by each model. Model 1 included adjustment for differences in age and race. Model 2 included adjustment for differences in age and race, as well as pack-years of smoking, alcohol use, BMI, total physical activity, hours of fasting, and diabetes status. Mean differences between women and men for Models 1 and 2 are significant ().
