Existing questionnaires on nutritional knowledge in India have serious limitations of not being validated using appropriate statistical techniques, questioning its ability to ensure a true measure of knowledge. The objectives of the present study were therefore, to design a validated knowledge questionnaire on micronutrients for adolescents and to use the tool to assess knowledge in a group of adolescent boys (16-18y) for the study on ‘Stress, allostatic load and micronutrient status among students; impact of dietary advice’. From a larger item pool, 31 items were selected after content analysis and pre-tested (n=94). Statistical measures like item difficulty, item validity (point bi-serial r=0.10-0.62) and reliability (Cronbach’s α=0.71) resulted in 18 item questionnaire. This was administered to a sub-sample of students (n=110) from a total of 405 students from five different Government schools belonging to 3 different regions of Greater Hyderabad. The results were compared against indicators of micronutrient status (α tocopherol, retinol, ascorbic acid, folic acid, vitamin B12 and iron). The students exhibited a low mean score of 5.2±2.68. The mean values of serum retinol (P=0.022) were significantly different between groups below and above 50th percentile of knowledge scores. Other micronutrients did not show any difference. Knowledge was found to be a significant predictor of serum retinol status on ANCOVA considering standard of living index as a co-variate (P<0.018). The valid and reliable questionnaire was able to discriminate adolescents based on indicators of micronutrient status (serum retinol) and thus a useful tool for intervention studies on nutrition advice involving micronutrients.
