Researchers obtained dietary histories from 489 adolescents aged 12-15 who were then followed up at the age of 20-25.
The researchers found there was a linear relationship between sugar intake at age 12-15 and insulin resistance. For every 1% increase in dietary sugar, there was a 2% increase in insulin resistance as assessed by HOMA-IR score.
Higher sugar intakes in adolescence were also associated with greater fasting plasma glucose at age 20-25. For every 1% increase in dietary sugar, there was a 0.01mmol/l increase in fasting plasma glucose.
The findings were presented at the Diabetes UK Annual Professional Conference in Liverpool last week.
