Table 6. Effect of home zinc on rates of reported morbidity at the household morbidity surveillance (HMS), western Kenya, from February 2008–March 2009, controlling for baseline rates of morbidity in home zinc and comparison villages.

	Pre-intervention*		Intervention†		Adjusted RR‡ (CI 95%)
	Intervention	Comparison	Intervention	Comparison
Person-years observed	1488	1690	1104	1206
Diarrhea	2.64	1.69	1.94	1.99	0.96 (0.79–1.15)
Diarrhea plus reported fever	0.94	0.87	1.04	1.10	0.94 (0.81–1.24)
Severe diarrhea	1.90	1.21	1.15	1.32	0.91 (0.73–1.13)
Diarrhea hospitalization (any hospital)	0.04	0.04	0.05	0.06	0.97 (0.42–2.23)
Acute Respiratory Illness	7.32	6.78	7.26	6.83	1.03 (0.95–1.12)
ALRI	0.28	0.24	0.18	0.28	0.68 (0.46–0.99)
Acute febrile illness	10.06	10.13	10.16	10.36	0.99 (0.91–1.07)

Rates are given as episodes per person-year.

*Pre-intervention period was October 2006 to November 2007.

^†While pre-intervention includes all children in the village of appropriate age, the intervention period only includes those enrolled in the home zinc study.

^‡Rate ratio is comparing rates between home zinc and comparison groups during the intervention period, adjusted for pre-intervention rates of the same syndrome in the child’s village, distance of village to Lwak and child’s age.
