Obesity has reached an alarming rate affecting all categories of the population. A tremendous rise in obesity has been observed in children and adolescents. In India, the prevalence of adolescent obesity is more than 30% of the population. Advanced glycation end products (AGEs) are a diverse group of compounds formed by the amalgamation of glucose and a protein moiety. These glycated compounds are found in processed foods subjected to high-temperature cooking techniques contributing to the formation of dietary AGEs (dAGEs). The enormous consumption of dAGE attributes to the development of metabolic diseases. The objective of this study was to develop and validate a food frequency questionnaire (FFQ) among obese adolescents aged 10-19 years to gauge their dAGE consumption. This questionnaire was developed from previous literature (15 articles), validated using the content validity ratio (CVR) by Lawshe, and estimated for reliability using the test-retest method. A pilot study was done among 50 obese adolescents aged 10-19 years, who completed the questionnaire twice, with a gap of 15 days. A total of 54 items were validated (CVR ≥0.99) from the 60 food items. A reliability score >0.7 was observed, and a significant correlation (P ≥ 0.01) between the test and retest results was determined. Hence, this FFQ is reliable and can be used for future research studies to elicit dAGE consumption among obese adolescents.
