Key result
Adults with diabetes had a significantly higher risk of suicide plans compared to the general population (aOR 2.926), with the risk showing an inverted U-shape peaking at 2 to 9 years of diabetes duration.
Why the study?
To investigate suicide risk in diabetes patients and evaluate variations in suicide risk according to the duration of diabetes in South Korea.
Does diabetes and its duration increase the risk of suicidal ideation, plans, and behavior in adults?
Cross-Sectional (n=6,296)
Does diabetes and its duration increase the risk of suicidal ideation, plans, and behavior in adults?
Odds Ratio: 2.926 (95% CI 1.325–6.463)
Absolute Event Rate: 3.6% vs 1.1%
p-value: p=<0.001
Diabetes is associated with an increased risk of suicidal ideation, plans, and behavior, with the highest risk observed in patients who have had the disease for 2 to 9 years.
May prompt suicide plan screening in diabetes; leaves open causality and needs longitudinal confirmation.
OBJECTIVE: The objectives of this study were to investigate the suicide risk in diabetes patients and evaluate the variations in suicide risk by the duration of diabetes using a large population sample in South Korea. METHODS: Data from 6,296 adults in the 2019 Korea National Health and Nutrition Examination Survey were included. The suicidal ideation, suicide plans, and suicidal behavior of diabetes patients were compared to the general population. After classifying the patients into ≤1 year, 2 to 9 years, and ≥10 years of diabetes duration, we evaluated the relationship between the duration of diabetes and the suicide risk. RESULTS: Diabetes patients had higher prevalences of suicidal ideation (9.1%, p<0.001) and suicide plans (3.6%, p<0.001) than the general population. After adjusting for potential confounding factors, suicide plans (adjusted odds ratio [aOR]=2.926, 95% confidence interval [CI]=1.325-6.463) were significantly associated with diabetes. In the 2 to 9 years group of diabetes patients, we found an increase in the risk of suicidal ideation (aOR=2.035, 95% CI=1.129-3.670), suicide plans (aOR=3.507, 95% CI=1.538-7.996), and suicidal behavior (aOR=7.130, 95% CI=2.035-24.978) after adjusting for the covariates. However, no increases in suicide risk were observed ≤1 year and ≥10 years after diabetes diagnosis. CONCLUSION: In adults, diabetes is associated with an increase in suicide risk. Suicide risk in diabetes patients showed an inverted U-shaped depending upon the duration of diabetes.

Kim et al. (2022) conducted a cross-sectional in Diabetes (n=6,296). Diabetes vs. General population without diabetes was evaluated on Suicide plans in the past year (aOR 2.926, 95% CI 1.325-6.463, p=<0.001). Adults with diabetes had a significantly higher risk of suicide plans compared to the general population (aOR 2.926), with the risk showing an inverted U-shape peaking at 2 to 9 years of diabetes duration.
