Exposure to liquid sweetness in early childhood: artificially-sweetened and sugar-sweetened beverage consumption at 4-5 years and risk of overweight and obesity at 7-8 years

BACKGROUND: A significant gap exists in longitudinal evidence on early exposure to artificially sweetened beverages (ASBs) and weight outcomes for paediatric populations.

OBJECTIVE: The objective of this study is to examine the relationship between ASB/sugar-sweetened beverage (SSB) consumption at 4-5 years and risk of overweight and obesity at 7-8 years.

METHODS: Data from a nationally representative cohort (n = 2986) in Scotland were analysed using logistic regression to evaluate the association between exposure to ASBs/SSBs at 4-5 years and risk of overweight and obesity at 7-8 years.

RESULTS: There were positive unadjusted associations between ASB consumption and risk of obesity, and following adjustment for confounders, ASB associations attenuated, and only the middle consumption category (1 to 6 times per week) remained significant (odds ratio 1.57, 95% confidence interval {CI} 1.05-2.36). For SSB consumption, there were no significant unadjusted associations, and following adjustment for confounders, only the middle consumption category was significant (odds ratio 1.65, 95% CI 1.12-2.44). There were no significant associations for risk of overweight.

CONCLUSIONS: Longitudinal analysis from 4-5 to 7-8 years demonstrated some evidence of associations between ASBs/SSB consumption and risk of obesity. However, non-linear patterns and wide CIs suggest cautious interpretation and need for future studies with long-term follow-up.
