Educational attainment and diabetes risk: triangulation evidence from UK Biobank prospective cohort, NHANES 2011-2018, and cross-trait genomics analyses
To examine the association between educational attainment and the risk of type 2 diabetes (T2D) using a triangulation framework of observational analyses, external validation, and genetic studies.
Approach:
Observational Analysis: Utilized UK Biobank data to assess associations of educational attainment with prevalent and incident diabetes.
Cross-Sectional Validation: Employed NHANES 2011-2018 data for external validation of findings.
Genetic Analysis: Conducted genome-wide analyses using public GWAS summary statistics to explore genetic correlations and pathways.
Key Findings:
Higher educational attainment was associated with lower odds of prevalent T2D (OR 0.76, 95% CI 0.72-0.79) and lower risk of incident T2D (HR 0.70, 95% CI 0.68-0.72) in UK Biobank.
In NHANES, college graduation or above correlated with lower prevalent T2D odds (OR 0.69, 95% CI 0.61-0.78).
Adiposity, smoking, alcohol use, and cardiometabolic biomarkers attenuated the education-T2D association.
Genetically predicted educational attainment showed an inverse relationship with BMI and T2D, identifying 19 shared multi-SNP gene signals.
Interpretation:
The study presents an association between higher educational attainment and reduced risk of T2D across multiple datasets.
Limitations:
The study primarily focused on T2D, with T1D presented as a secondary outcome.
Potential confounding factors may not have been fully accounted for in observational analyses.
Conclusion:
Higher educational attainment is linked to lower T2D risk, highlighting the relevance of metabolic and behavioral pathways.
Preoperative use was associated with fewer revisions and no increase in short-term complications among patients with obesity, although benefits appeared concentrated in select subgroups.
