In a longitudinal study of 200 randomly selected underfives were followed fortnightly for a period of one calendar year (January to December 91) to ascertain the influence of undernutrition and vitamin A deficiency on the ARI incidence. The study revealed that on an average a child suffered from 5.9 episodes of ARI in one year period. Children who were undernourished or showed signs of vitamin A deficiency had significantly greater risk of AIR attacks.
PIP: Acute respiratory infections (ARI) are an important cause of morbidity and mortality in children under age 5 years. Host factors such as undernutrition and vitamin A deficiency appear to play a dominant role in the incidence of ARI. The authors followed fortnightly a sample of 200 randomly selected under-fives for the calendar year January-December 1991 to determine the influence of undernutrition and vitamin A deficiency upon the incidence of ARI. The children collectively experienced 1172 episodes during the course of the year for an average 5.9 episodes of ARI each. Each ARI episode lasted for a mean period of 7.2 days. Children who were undernourished or showed signs of vitamin A deficiency were at significantly greater risk of ARI attacks.
