Cereal-based oral rehydration therapy. II. Strategic issues for its implementation in national diarrheal disease control programs. Field studies in Bangladesh demonstrated that after proper training, village mothers were able to prepare and use rice-based, salt-enriched oral rehydration solutions containing safe concentrations of sodium, and were capable of achieving significantly fewer treatment failures and a reduction in the duration of diarrhea than with glucose-based oral rehydration solutions (ORS). An additional longitudinal study showed that improved growth and weight gain occurred with the consistent use of ORS; the effect was greater when rice-based ORS were used. In addition, the following possible limitations and benefits of cereal-based oral rehydration therapy, which are relevant to the strategies for its implementation in national diarrheal disease control programs, are discussed: safety, osmolarity, hypernatremia, spoiling, effectiveness, rehydration ability, reduction in diarrhea volume and duration, nutritional effects, effect on food intake, acceptance and usage by care givers, training of health workers, self-reliance of families, effect on other child survival activities, costs, potential problems in changing to cereal-based ORS, and the role of industrial production in packaged cereal-based ORS.
