Associations Between CMV and HSV-1 Seropositivity and WRAT-R Scores Among Children Aged 6–16 or 12–16 Years in NHANES III, 1988–1994

Seropositivity	Block Design		Digit Span
	Model 1^a	Model 2^b	Model 1^a	Model 2^b
	β (95% CI)	β (95% CI)	β (95% CI)	β (95% CI)
CMV	−0.49 (−.86 to −.12)^c	0.03 (−.34 to .41)	−0.16 (−.53 to .21)	0.19 (−.13 to .51)
HSV-1	−1.54 (−2.10 to −.99)^c	−0.82 (−1.29 to −.36)^c	−0.66 (−1.14 to −.19)^c	−0.04 (−.63 to .55)

Abbreviations: CMV, cytomegalovirus; HSV-1, herpes simplex virus-1; NHANES, National Health and Nutrition Examination Survey; WRAT-R, Wide Range Achievement Test–Revised.

^a Model 1 for CMV and block design (n = 4303), CMV and digit span (n = 4299), HSV-1 and block design (n = 1393), and HSV-1 and digit span (n = 1393), unadjusted.

^b Model 2 for CMV and block design (n = 3938), CMV and digit span (n = 3934), HSV-1 and block design (n = 1262), and HSV-1 and digit span (n = 1262), adjusted for age, sex, race/ethnicity, country of origin, poverty-income ratio, family educational level, smoke exposure (HSV-1 models only), and census region (CMV block design model only).
