Objective: To assess tracking of energy and nutrient intakes of adolescents of Ho Chi Minh City in five years and to explore the possible relationships between energy and percentage of energy from macronutrients with BMI in adolescents.

A 5-year prospective cohort study was conducted between 2004 and 2009. Height, weight were measured; and time spent for physical activity, TV viewing and dietary intake were collected annually among 759 junior high school students in Ho Chi Minh City. The extent of tracking of energy and macronutrient intakes (assessed by food frequency questionnaire) was investigated using Spearman correlation coefficients and weighted kappa statistics (k). Generalized Linear Latent and Mixed Models were used to investigate the association between energy intake and percentage energy from protein, carbohydrate and fat with BMI.

There was a significant increase in mean BMI and median energy, macronutrient intakes with increasing age, higher in boys than in girls (p
The poor to fair 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.
