Nature vs nurture of glucose homeostasis trajectories in children from the ALSPAC study
Genetic risk scores combined with lifestyle data can identify which young people will develop prediabetes, enabling earlier and more personalized prevention efforts.
Adding polygenic risk scores to environmental predictors improved dysglycemia prediction in youth (AUC to 0.78 by age 15), while identifying actionable gene-environment interactions: high genetic risk compounded by screen time increased insulin resistance, but physical activity attenuated this. These findings support early genetic risk stratification combined with targeted lifestyle interventions for youth prediabetes prevention, with 24% prediabetes prevalence observed by age 24.

Why it surfaced
Large longitudinal cohort (n=8,783) identifying gene×environment interactions on glucose trajectories from childhood; modifiable targets (screen time, physical activity) identified; relevant for early prevention in high-genetic-risk youth.
