TABLE 3.

Mean number of servings per day of food groups estimated from four 24-h dietary recalls by using dietary screening tool (DST) risk classifications for older adults residing in rural Pennsylvania¹

	At-risk group, DST score <60 (n = 58)	Possible-risk group, DST score 60–75 (n = 93)	Not-at-risk group, DST score >75 (n = 53)
Fruits and vegetables	3.1 (2.6, 3.6)^a	4.6 (4.2, 5.0)^b	5.5 (4.9, 6.0)^c
Fats and oils	3.8 (3.4, 4.2)^a	3.2 (2.8, 3.6)^b	3.0 (2.5, 3.5)^b
Sweets	1.4 (1.2, 1.9)^a	1.1 (0.9, 1.4)^a,b	0.8 (0.5, 1.2)^b
Low-fat dairy	0.34 (0.2, 0.5)^a	0.49 (0.4, 0.6)^a	0.82 (0.7, 0.9)^b
Whole- and reduced-fat dairy	0.58 (0.4, 0.7)	0.54 (0.4, 0.7)	0.38 (0.2, 0.5)
Whole grains	1.2 (0.8, 1.5)^a	2.2 (1.9, 2.6)^b	2.2 (1.9, 2.6)^b
Refined grains	4.3 (3.7, 4.6)^a	3.4 (3.0, 3.7)^b	2.9 (2.6, 2.5)^b

All values are means; confidence limits in parentheses. ANOVA models are adjusted for sex. Values in the same row with different superscript letters are significantly different, P ≤ 0.05 (ANOVA using a general linear model with Tukey-Kramer adjustment for multiple comparisons).
