Objectives: This study aimed to examine whether physical activity and consumption of fruits and vegetables were associated with the risk of developing glaucoma.

Methods: The Household, Longitudinal component of the Canadian National Population Health Survey database was used. Weighted crude and adjusted Cox proportional hazards models were fitted with time-dependent covariates. The adjusted models were controlled for age, sex, BMI, cigarette smoking, alcohol consumption, diabetes mellitus, arterial hypertension, heart disease, education, and income.

Results: A total of 9,950 respondents were included, of which 190 developed glaucoma within the 10-year follow-up period. The adjusted hazards ratios for physical activity and fruit and vegetable consumption were 0.99 [95% CI: 0.87, 1.12] and 1.03 [95% CI: 0.93, 1.14], respectively.

Conclusion: The results suggest that physical activity and consumption of fruit and vegetable are not associated with the risk of developing glaucoma. Future studies should consider including other aspects of diet and physical fitness.
