TABLE 2.

Effects of an integrated agriculture, nutrition, and health intervention on nutrition and health knowledge scores among a cohort of 505 women participating in the Mama SASHA cohort study in Western Kenya¹

	Scores at enrollment			Mean increase in scores from enrollment to the 9-mo postpartum visit
Index scores (possible range)	INT (n = 250)	CON (n = 255)	P-difference2	INT (n = 193)	CON (n = 192)	DiD (95% CI)3
Nutrition and health knowledge (0–14)	3.7 ± 2.3	3.4 ± 2.2	0.45	2.6 ± 2.7	1.6 ± 2.2	1.0 (0.1, 1.9)*
VA knowledge domain (0–4)	1.0 ± 1.2	0.6 ± 1.2	0.04	1.0 ± 1.5	0.2 ± 1.2	0.8 (0.4, 1.2)‡
IYCF knowledge domain (0–8)	2.2 ± 1.5	2.4 ± 1.3	0.15	1.5 ± 1.8	1.2 ± 1.4	0.4 (−0.3, 1.1)

¹Values are mean ± SDs. *P < 0.05, ^‡P < 0.01. CON, control; DiD, difference in difference; INT, intervention; IYCF, infant and young child feeding; Mama SASHA, Sweetpotato Action for Security and Health in Africa; VA, vitamin A.

²P values for the difference in mean scores at enrollment estimated from cluster-adjusted regression analyses.

³Estimates and 95% CIs for differences in mean change in knowledge scores estimated from restricted maximum likelihood estimation by using mixed-effects models.
