ABSTRACT

Objective. To examine the relationship between the Time of Attendance (TA) and the Incidence Rate of Diarrhea (IRD) in a group of infants who attended a Day-Care Center (DCC) in Merida, Yucatan, Mexico.
Design. Observational, and prospective epidemiological study.
Subjects. Infants from 1.5 to 23 months old, who attended a DCC since the 1^st of August 1996 until the 31^st of July 1997.
Measurements. The number of episodes of diarrhea, and the time at risk of diarrhea in a group of infants classified as exposed if TA£30 days, and as unexposed if TA›30 days.
Results. Taking into account the age variable, the IRD is 41% higher in the exposed group compared to the unexposed, and the Incidence Rate Ratio of Diarrhea (IRRD) has an average decrement of 49% across the groups of age when the IRRD from a Group of Age (GA) is compared to the IRRD of the next group of older age.
Conclusions. TA has a detrimental effect over the IRD in infants with TA£30 days, and GA has a protective effect over the IRD when infants change from a GA to the next group of older age.
