Dietary Magnesium Intake and Leukocyte Telomere Attrition in Adults: The Regulatory Role of Serum Tumor Necrosis Factor α

Table 2

LTL and TNFα by quartiles according to magnesium intake per 1000 kcal energy.

	Model	Q1 ()	Q2 ()	Q3 ()	Q4 ()	for trend	Q4–Q1	% of Q1
Mg						—	—	—
LTL	1					<0.001	-0.53	-1.8
	2					<0.001	-0.55	-1.9
TNFα	1					0.004	4.02	18.9
	2					0.006	3.79	17.6

Statistical significance was inferred when the value was less than 0.05; results are depicted as ; ANCOVA was used to derive the for trend values. Q4–Q1 is the value in Q4 minus the value in Q1. % of Q1 represents the difference between Q4 and Q1 with respect to the Q1 value. Model 1 was adjusted for sex and age, whereas Model 2 was adjusted for hypertension, central obesity, sex, age, HbA1c, LnTG, and HDL-C.
