For infants who had been weaned, information was not collected on the types of food they were weaned onto, but data were available on consumption of foods in the 10 days prior to symptoms in
cases (interview in controls), but none were significantly associated with
diarrhoeal disease (data not shown).
Population attributable fractions (PAFs) for
diarrhoeal disease associated with infant feeding variables were estimated as (proportion of
cases exposed) × (OR − 1) / OR.13 Survival analysis was used to estimate the prevalence of breast feeding at age 6 months while allowing for censoring, due to some infants being aged under 6 months.

diarrhoeal disease.
