Objective: To develop and evaluate a Nutrition Transition-FFQ (NT-FFQ) to measure nutrition transition among adolescents in South India.
Design: We developed an interviewer-administered NT-FFQ comprising a 125-item semi-quantitative FFQ and a twenty-seven-item eating behaviour survey. The reproducibility and validity of the NT-FFQ were assessed using Spearman correlations, intra-class correlation coefficients (ICC), and levels of agreement using Bland-Altman and cross-classification over 2 months (NT-FFQ1 and NT-FFQ2). Validity of foods was evaluated against three 24-h dietary recalls (24-HR). Face validity of eating behaviours was evaluated through semi-structured cognitive interviews. The reproducibility of eating behaviours was assessed using weighted kappa (K-w) and cross-classification analyses.
Setting: Vijayapura, India.
Subjects: A representative sample of 198 adolescents aged 14-18 years.
Results: Reproducibility of NT-FFQ: Spearman correlations ranged from 0.33 (pulses) to 0 . 80 (red meat) and ICC from 0.05 (fruits) to 1.00 (tea). On average, concordance (agreement) was 60% and discordance was 7% for food groups. For eating behaviours, K-w ranged from 0.24 (eating snacks while watching television) to 0.67 (eating lunch at home) with a mean of 0.40. Validity of NT-FFQ: Spearman correlations ranged from 0.11 (fried traditional foods) to 0.70 (tea) and ICC ranged from 0.02 (healthy global foods) to 1.00 (grains). The concordance and discordance were 48% and 8%, respectively. Bland-Altman plots showed acceptable agreement between NT-FFQ2 and 24-HR. The eating behaviours had acceptable face validity.
Conclusions: The NT-FFQ has good reproducibility and acceptable validity for food intake and eating behaviours. The NT-FFQ can quantify the nutrition transition among Indian adolescents.
