Diabetic retinopathy (DR) is an important complication of diabetes mellitus (DM) and is the main cause of visual impairment and blindness
.
DR can significantly affect a person's quality of life
Diabetic retinopathy (DR) is an important complication of diabetes mellitus (DM) and is the main cause of visual impairment and blindness
Coffee is one of the most consumed beverages globally
.
Over the past few decades, many studies have investigated the relationship between coffee drinking and various diseases, including cancer, Alzheimer's, cardiovascular disease, and type 2 diabetes
Despite the interest in the relationship between coffee drinking and diabetes, few studies have evaluated the relationship between DR and coffee drinking
Of the 37,753 survey participants, data from 1,350 participants diagnosed with type 2 diabetes who underwent DR testing were analyzed (Figure 1)
.
The prevalence of any DR and vision-threatening DR (VTDR) in this population was 20.
Of the 37,753 survey participants, data from 1,350 participants diagnosed with type 2 diabetes who underwent DR testing were analyzed (Figure 1)
After adjusting for potential confounders, coffee consumption was found to be inversely associated with the prevalence of any DR and VTDR (P for any DR, P for trend = 0.
025 and for VTDR, P = 0.
005 for trend; Table 2)
.
After adjustment, participants who drank ≥2 cups of coffee per day had lower DR (OR 0.
After adjusting for potential confounders, coffee consumption was found to be inversely associated with the prevalence of any DR and VTDR (P for any DR, P for trend = 0.
This downward trend in DR according to coffee consumption became more pronounced among participants under the age of 65 when the population was divided into two groups according to age (Figure 2)
.
After adjustment, the general trend that coffee consumption was inversely related to the prevalence of any DR and VTDR became more significant (P for trend = 0.
This downward trend in DR according to coffee consumption became more pronounced among participants under the age of 65 when the population was divided into two groups according to age (Figure 2)
Demographic characteristics of the two groups (<65 years and ≥65 years) were compared
.
People over the age of 65 lived longer with diabetes, had higher rates of high blood pressure, and had a higher percentage of people who drank a cup of coffee a day
.
This group had a lower proportion of males, lower education levels, lower income levels, lower alcohol and tobacco consumption, lower BMI, and lower HbA1c

This group had a lower proportion of males, lower education levels, lower income levels, lower alcohol and tobacco consumption, lower BMI, and lower HbA1c
.
Next, the correlation between the prevalence of DR and the type of coffee consumption was analyzed (Table 3)
.
Those who drank black coffee had lower odds of developing DR (P = 0.

.
This trend was the same in the sugar-sweetened or creamed coffee group (P for trend = 0.

.
Taken together, this study found that participants who drank ≥2 cups of coffee per day had a lower prevalence of DR and VTDR compared with those who drank less than 1 cup of coffee per day
.
Furthermore, trend analysis found an inverse relationship between coffee consumption and the prevalence of DR and VTDR
.
Regardless of the type of coffee, the prevalence of DR decreased with increasing intake of black coffee and coffee with added sugar or cream

In conclusion, this study showed that coffee intake was inversely related to the prevalence of DR in Koreans with diabetes under the age of 65, suggesting that coffee consumption may be associated with a reduction in DR
