Abstract
This paper examines household and community-level influences on diarrhoeal
prevalence in southern Malawi. A Bayesian multi-level modelling technique is used
in the estimation of hierarchically built data from a survey of individuals nested
within households nested within communities. Households have strong unobserved
influence on diarrhoeal illness (s2u
¼ 4.476; 95%CI: 2.081, 6.871). A joint Wald test
of significance shows that an individual's age [w24
¼ 55:921; p ¼ 0:000] and school
[w22
¼ 18:203; p ¼ 0:000] have strong influence on an individual's diarrhoeal
prevalence. An individual's history of malarial-like illness also has a strong
positive relationship with diarrhoeal prevalence [b ¼ 0.606, p ¼ 0.000]. Household
factors that influence diarrhoea include employment status of head of household
[b ¼ 70.619, p 5 0.021], maternal age [b ¼ 70.013, p 5 0.003], and size of
household [b ¼ 70.669, p ¼ 0.000]. The positive relationship between diarrhoea
and malaria-like episodes highlights common risk factors hence the need for
common approaches to combat the diseases. Significant household effects underline
the importance of household considerations in policy issues.
