Researchers analyzed 1976-88 data from rural Matlab in Bangladesh to examine changes in diarrhea and in acute watery diarrhea mortality among infants and children before and after the implementation of an oral rehydration therapy (ORT) program. Overall diarrhea mortality among infants increased consistently (3-13) in both the area with maternal and child health-family planning (MCH-FP) services and the comparison area (p<.001). Mortality from acute watery diarrhea among infants also rose in both areas (1-7; p<.001). Trends in diarrhea mortality among children were not as straightforward however. It peaked in 1983-84 due to a dysentery epidemic. 92% of mothers in both areas knew about the benefits of glucose and oral rehydration salts (G-ORS) packets or homemade ORT solutions but most mothers (78% in MCH-FP area and 85% in comparison area) incorrectly believed ORT would stop diarrhea. Only 58% of G-ORS local distributors had G-ORS packets on the day the community health worker visited. Infants with severe acute watery diarrhea ingested a mean of 400 ml of ORS during the 1st 2 days of illness which is inadequate to treat infants with severe dehydration or high purging rates. ORT promotion and home distribution of G-ORS did not decrease infant and child deaths from acute watery diarrhea. Possible reasons for this phenomenon are suggested: complications other than dehydration the small amounts of ORS used and reduced reliance on hospitals and increased delays before taking severely ill children to the hospital. The question of whether the relative increase in diarrhea deaths among infants was due to the decline in infant mortality from other diseases thus making diarrhea a predominant replacing disease in the Matlab was considered. The results indicated that health educators should work toward formulating clear messages which promote correct use of ORT. Health workers should consider ORT as 1 component among others in diarrheal disease control programs.
