Table 1. Incidence rate ratios (IRR)a for predictors of diarrhoea in children aged under 5 years derived using a random effects negative binomial model,b Matlab, Bangladesh, 2005–2006
|Deep tube well use||0.541||0.308–0.949||0.032|
|No. of children aged < 5 years in the household||1.988||1.434–2.755||0.0001|
|Maternal educational level||0.932||0.858–1.012||0.094|
|Household socioeconomic status||0.983||0.840–1.151||0.835|
|Population density in the vicinity of the householdd||0.999||0.987–1.012||0.911|
CI, confidence interval.
a An IRR of 1 indicates that the independent variable has no effect on the risk of diarrhoea, while an IRR greater than 1 indicates an increased risk and an IRR below 1, a decreased risk.
b The model considered 927 observations from a total of 543 households.
c Number of latrines within 30 metres of a household.
d Number of people living within 30 metres of a household.
e The study years were 2005 and 2006.
