Background: The added sugar intake of children and adolescents in Canada warrants more research due to its contribution to obesity, diabetes, and other chronic and mental health issues.

Objective: To assess the trends and correlates of added sugar intake in Canadians aged 6 to 17.

Methods: Data were provided by the Canadian Community Health Survey-Nutrition 2004 and 2015. Statistical analysis included multivariable regression and t-tests.

Results: In 2015, 35.66% of Canadians aged 6 to 17 met sugar intake guidelines. Compared to 2004, in 2015 intake of fruit and vegetables was higher, while sugar and caloric intake was lower. Sedentary activity, sex, age, race, household income, and region of residence were risk factors for high added sugar intake.

Conclusion: Dietary habits have improved from 2004 to 2015, but average sugar intake continues to surpass the recommended amount. Significant correlates were identified, but more research is needed to investigate variations in intake.
