Mean Intake of Micronutrients by Age Group among Female Participants in the OPREVENT2 Study

	19–30 y (n = 73)	31–50 y (n = 154)	51–70 y (n = 182)	71–75 y (n = 19)
	Mean (SE)
Vitamin A (μg RAE)	698.9 (52.2)	698.3 (32.8)	644.5 (33.8)^a	604.4 (74.1)
Vitamin C (mg)	111.8 (9.3)^{c, d}	96.1 (5.0)^c	73.3 (3.9)	60.8 (10.3)
Vitamin D (IU)	118.2 (13.0)	117.6 (8.1)	116.9 (8.9)^a	137.7 (31.8)^a
Sodium (mg)	3869.0 (313.9)	3532.1 (181.7)	3107.2 (145.9)^a	2736.8 (301.6)
Folate (μg DFE)	556.2 (44.4)	504.1 (24.0)	459.4 (24.4)^a	404.2 (51.1)
Zinc (mg)	12.8 (1.1)	12.2 (0.7)^{a, d}	10.9 (0.6)^a	10.3 (1.3)^a
Calcium (mg)	956.7 (66.4)	885.1 (40.4)	776.9 (39.5)	783.3 (107.1)
Iron (mg)	16.7 (1.3)	15.3 (0.7)	13.8 (0.7)^{a, b}	12.5 (1.6)^a

SE = Standard Error of Mean, RAE = Retinol Activity Equivalent, DFE = dietary folate equivalent

Each column’s age category is assigned a letter accordingly:

= 19–30y,

= 31–50y,

= 51–70y,

= 71–75y.

Lower case superscript letters in each column indicate statistically significant age group comparisons of mean nutrient intakes after adjusting for total energy intake (p < 0.05), with the letters shown beneath the highest value of the comparisons.
