Objective:

To investigate the association between long-term exposure to high insulin levels during childhood and adulthood and changes in retinal microvasculature in adulthood in a population without diabetes.

Key Findings:
  • Higher cumulative insulin exposure in childhood, adulthood, and lifelong was associated with decreased retinal arteriolar diameter.
  • These associations remained significant after adjusting for age, sex, and conventional cardiovascular risk factors.
Interpretation:

Long-term exposure to high insulin levels may adversely affect retinal microvasculature, potentially contributing to cardiovascular disease risk.

Limitations:
  • The study population was limited to individuals without diabetes, which may affect generalizability.
  • Causal relationships cannot be established due to the observational nature of the study.
Conclusion:

Cumulative insulin exposure is linked to adverse changes in retinal microvasculature, highlighting the importance of monitoring insulin levels for cardiovascular health.
