Abstract
Purpose: Assessing diabetic retinopathy (DR) risk factors and daily nutrition habits are vital for prevention. This study aims to evaluate the relationship between diet soda cans, nonnutritive sweetener consumption, and diabetic retinopathy.
Patients and Methods: A cross-sectional study was conducted among 200 patients attending a diabetes center in Tabuk City, Saudi Arabia, from September 2019 to July 2020. A structured questionnaire was used to collect patients' demographic factors, and DR risk factors including the use of diet soda, non-nutritive sweeteners, and exercise habits. Dilated fundus eye examination was done to detect any diabetic retinopathy. A blood sample was taken for measuring glycated hemoglobin to assess the degree of glycemic control.
Results: The participant's age was 50.74 +/- 13.51 years, and the duration since the diagnosis of diabetes was 9.99 +/- 6.97 years, body mass index was 27.28 +/- 4.68, and HbA1c %, 8.50 +/- 1.61), the patients used to consume 1.31 +/- 1.57 diet soda cans/week, and 1.06 +/- 1.39 artificial sweeteners/sachet/day. DR was found in 33%. Diet sugar-free carbonated soda beverage was associated with poor glycemic control and retinopathy, while non-caloric flavor consumption was associated with obesity (P-value<0.05). No association was evident regarding other factors (P-value>0.05).
Conclusion: Diet sugar-free carbonated soda beverage was associated with higher HbA1c and retinopathy, while non-caloric flavor consumption was associated with obesity. No association was evident regarding other factors. Further larger multicenter studies are needed.
