A case-control study of acute diarrheal disease among school-age children in southern Thailand.
We conducted a case-control study of school-age children in Phatthalung, a province in southern Thailand using a questionnaire to investigate associations of children's hygiene-related behavior and hygienic conditions in their homes with acute diarrheal disease. We compared 69 acute diarrhea (less than 7 days duration) cases that attended two hospitals in Phatthalung during August 1995 to June 1996 with 69 age-, sex- and address-matched controls in primary schools who had not suffered from diarrheal disease for the past one year before August 1995. Three factors were found to be significantly associated with acute diarrheal disease: farmer or gum planter as the occupation of father [Odds ratio (OR) 6.6; 95% confidence interval (CI) 1.7-26.1, p < 0.01], installation of a refrigerator in children's homes (OR 0.2; CI 0.1-0.8, p < 0.05), and drinking untreated water (OR 2.3; CI 0.9-6.1, p < 0.1). There was no significant difference for sources of drinking water between cases and controls. Considering the data on drinking water, the results indicated that there are some problems with quality of sources of drinking water. The results also suggested that having a refrigerator could have preventive effects on acute diarrheal disease, while inadequate behavior and unhygienic environment in the homes of farmers and gum planters might be related to acute diarrheal among school-age children.
