Objective: To explore the relationships between energy, proportion of energy from macronutrients and BMI in junior high school students of HCM city. Methods: A cohort study was conducted between 2004 and 2009. Data on BMI, time spent for physical activity, TV watching habit and dietary intake were collected annually among 759 junior high school students. The extent of tracking of energy and macronutrient was investigated using Speannan correlation coefficients and weighted kappa statistics. Generalized Linear Latent and Mixed Models were used to investigate the association between energy intake and proportion of energy from protein, carbohydrate and fat with BMI. Results: Tracking of energy and macronutrient nutrient intakes at individual level was lowest for the percentage of energy from carbohydrate and from protein and highest for fat intakes (correlation coefficients and Kappa values were 0.38 and 0.29 for boys, and 0.29 and 0.27 for girls, respectively). The linear multi-level models showed that none of variables were significantly associated with BMI. Conclusions: The varied tracking observed in this cohort suggests that individual dietary patterns exhibited at the first year are unlikely to be predictive of energy and nutrient intake at the last year.
