Limiting factors of ORS intake.

ABSTRACT

This was a thirty cluster survey; carried out to identify the factors which limit ORS intake during a diarrhoeal episode in rural Bangladesh. 420 mother-child pairs were investigated. In addition to the verbal interview, the index child was examined physically and mother's skill of preparing ORS was assessed. The ORS was known to more than 95% mothers but used by only 33.3%. The average intake of ORS was 320 ml per diarrhoea day. The correct amount of oral rehydration fluid was received by 145(34.5%) cases. Twenty eight socio-demographic-maternal-host(child)-environmental factors were studied for their probable influence on intake of correct amount of oral rehydration fluid. In bivariate analysis, fourteen factors were found to be associated significantly with oral rehydration fluid intake (P < 0.05-< 0.0001). These fourteen factors were treated with stepwise logistic regression analysis. Sensitivity and specificity were the key measures for decision of best fitted model. A combination of child age, mother's education, socio-economic condition and method of feeding ORS provide the maximum sensitivity (90.20%) and specificity (74.19%) for predicting oral rehydration fluid intake. The study emphasized the need for further strengthening of health education incorporating the findings of the research to ensure required amount of oral rehydration fluid intake during diarrhoeal episode.
