Brief summary

Previous studies suggested dietary sugar consumption as one of the main factors of obesity, yet the findings on children were inconsistent. Notably, although the consumption of sugar-sweetened beverages (SSB) was found to be positively associated with body weight gain in children, the association between the consumption of free sugar, as defined by the World Health Organization (WHO), and weight gain on children remained inconclusive. Hence, the current analysis aimed to assess the effects of consuming free sugar on the BMI z-score of a group of Australian children and adolescents.

Informed consent was obtained from the primary caregiver or a responsible adult for children aged less than 14 years, while adolescents aged 14 years or above provided their own consent in the presence of a parent or responsible adult
