Simple piped water supply (PWS) is increasingly popular in rural areas of southem Thailand where diarrheal diseases are quite common.
The current study was carried out in 1990 in the southem part ofThailand to determine whether the use of PWS could significantly reduce the incidence rate of diarrheal diseases among the children under two years of age.
A dynamic cohort study started in January 1990 in seven Muslim villages where PWS was installed for some time and there was a mixture of PWS users and non-users in each village.
The cohorts comprised 126 and 137 children using and not using PWS, respectively.
They were followed up weekly for one year.
The crude incidence rates of diarrhea episodes for children using and not using PWS were 2.54 (SE=0.21) and 3.52 (SE=0.18) episodes per child-year, respectively (p<0.01).
The number of diarrheal attacks in each week was modeled as a Poisson variate using a generalized estimating equation, adjusting forcorrelation within the child.
The analysis was carried out for each village separately and meta-analysis was used to combine these analyses.
It was concluded that diarrheal disease in the study area was mild but the incidence rate was high.
The effect of PWS on the incidence rate of diarrhea varied with locality.
PWS systems in these communities were unstable and needed improvement in management.
