Prevention of diarrhoea in a poor District of Santo Domingo, Dominican Republic: practices, knowledge, and barriers.

The study, conducted in a poor periurban community of Santo Domingo, Dominican Republic, assessed the practices, knowledge, and barriers relating to prevention of diarrhoea. A total of 582 caregivers of children, aged less than 5 years, were systematically sampled from four barrios. Results of the study showed that 55% of the caregivers did not boil drinking water for children; 38% did not always wash hands of the children prior to meals; 87% of the children did not always wear shoes outside their house; and 54% were breastfed for less than one year. Biomedical knowledge about these practices was high among the caregivers, and was not related to the reported behaviours. However, several barriers were significantly related to practices, including lapse in caregiving, limited resources, erroneous beliefs, and non-compliance by children. Health education, based on a biomedical knowledge-deficit model, may have little impact on improving the diarrhoea-prevention practices in these communities. Greater attention should, therefore, be directed toward the barriers experienced by caregivers of children.
