Dietary total antioxidant capacity is inversely associated with depression, anxiety and some oxidative stress biomarkers in postmenopausal women: a cross-sectional study

Table 4 Adjusted mean values for serum biomarkers of oxidative stress across tertiles of energy-adjusted DTAC (n = 175)

Variables	Tertiles of energy-adjusted DTAC
	T1 (n = 58)		T2 (n = 59)		T3 (n = 58)		P-value*	Effect size of ANCOVA test
	Mean	95% CI	Mean	95% CI	Mean	95% CI	P-value*	Effect size of ANCOVA test
TAC (mM)	0.44	0.42–0.45	0.46	0.44–0.47	0.44	0.42–0.45	0.04	0.03
MDA (µM)	5.3	4.7–6.0	4.8	4.2–5.4	3.4	3.0–3.8	< 0.001	0.13
Ox-LDL (ng/l)	1548.8	1339.6–1794.7	1655.7	1432.1–1918.6	1489.3	1285.2–1725.8	0.6	0.03
SOD (U/ml)	36.0	34.1–38.1	33.8	32.0–35.8	33.9	31.9–35.7	0.1	0.02

Values are geometric means and 95% CI
DTAC dietary total antioxidant capacity, TAC total antioxidant capacity, MDA malondialdehyde, Ox-LDL oxidized low-density lipoprotein, SOD superoxide dismutase
* ANCOVA test, adjusted for age, time since menopause, education (year), waist circumference (cm), physical activity (MET min/week), dietary supplement use (yes/no), dietary intake of fiber (g/day), energy (kcal/day), and coffee (g/day)
