Dietary vitamin A intake and the incidence of diarrhea and respiratory infection among Sudanese children.
The relationship of vitamin A deficiency and child survival has been documented in a number of studies but not in others, yet the relationship of vitamin A with child morbidity remains controversial.
We prospectively examined the relationship of dietary vitamin A intake and the incidences of diarrhea and respiratory infection among 28,753 Sudanese children between the ages of 6 mo and 6 y. Total dietary vitamin A intake was strongly and inversely associated with the risk of diarrhea (multivariate risk in top relative to bottom quintile=0.58,95% confidence interval=0.47-0.72) ; we also observed a strong inverse association with the risk of having cough and fever (0.60,0.45-0.81).
On the other hand, we noted a significantly positive association of dietary vitamin A intake and incidence of cough alone (1.69,1.52-1.88), a sign that may be associated with a healthy respiratory epithelium.
Vitamin A intake was also negatively associated with the risk of measles.
These prospective data emphasize the importance of adequate dietary vitamin A intake to protect the health of children in developing countries.
