Abstract
Five hundred healthy school children in the age group 5-9 years underwent tuberculin testing. Seventy nine per cent of the study population had a BCG scar. 9.2% children were found to be suffering from malnutrition, using the Quetlet's Index and 7.8% were found to be malnourished by weight for age method. 18.6% of the children were tuberculin positive (induration > or = 10 mm) and the prevalence of tuberculin positivity increased with age. The numbers of tuberculin reactors or the mean tuberculin reaction were not affected by malnutrition. BCG scar status neither affected the mean tuberculin size nor the number of tuberculin reactors.
