Oral Rehydration Therapy (ORT) use in Nigeria is currently far short o
f the national Control of Diarrhoeal Diseases (CDD) programme goals. T
owards designing health education strategies to improve this, maternal
lay health concerns during diarrhoea in under-fives were examined amo
ng two large ethnic groups, the Kanuris and Buras, in northeastern Nig
eria. Over half of the respondents judged the severity of diarrhoea by
more than one sign and expected ORT to stop diarrhoea. Severity signs
frequently described (averaging from a quarter to a half of responden
ts) included weakness and refusal of food; frequent stooling and fever
were more frequently used by the Kanuris (p < 0.001) compared to Bura
s and weight loss and dehydration by the Buras (p < 0.01) compared to
Kanuris. Generally, rural residents were less concerned with dehydrati
on and weight loss (p < 0.0001 and 0.003 respectively, compared to urb
an residents) and more concerned with restlessness, including excessiv
e crying (p < 0.07 to 0.0001). Stool characteristics and vomiting were
rarely used as severity signs although the Kanuris in focus group dis
cussions related severity to diarrhoea typology. Concerns with persist
ent diarrhoea, and diarrhoea associated with measles, were rarely expr
essed by participants, irrespective of ethnic group and domicile, sugg
esting that health education aimed at increasing awareness in relation
to these two serious illnesses is urgently needed in Nigeria. Several
of the lay health concerns expressed by participants in the study cou
ld form a useful basis for promoting ORT use in Nigeria and elsewhere.
