The direct and indirect effect associations of usual free sugar intake on BMI z-scores of Australian children and adolescents

18 / 06 / 18

Finding: Free sugar intake was not associated with BMI z-score in Australian children and teens.

Summary: A cross-sectional analysis of the 2007 Australian National Children’s Nutrition and Physical Activity Survey was performed using structural equation modelling to assess the association between usual free sugar intake and age- and sex- specific BMI z-score. Indirect association via energy overconsumption was also assessed. Weak and non-significant associations were found for both direct and indirect pathways. The authors concluded that free sugar intake was not associated with BMI z-score in this cohort and improving the whole diet may be a better approach than focussing on free sugar intake to reduce childhood obesity.

Direct pathway is the direct association between sugar intake and BMI z-score

Indirect pathway is the association between energy overconsumption and BMI z-score
