Sex-specific factors associated with suicidal ideation among individuals with type 2 diabetes include marriage and fatigue in men, and elevated creatinine, smoking, and fatigue in women, highlighting the need for tailored suicide risk screening by gender.
Key Findings
Results
Being married was significantly associated with increased suicidal ideation in men with type 2 diabetes.
Adjusted odds ratio (AOR) for marriage in men = 4.54
Cross-sectional study of 695 adults with T2D at a university hospital outpatient clinic
406 (58.4%) of participants were men
Mean age of sample was 60.5 (SD = 11.8)
Multiple logistic regression was used to identify sex-specific factors
Results
Living with someone was associated with significantly lower suicidal ideation in men with type 2 diabetes.
AOR for living with someone in men = 0.16, indicating a protective effect
This finding suggests that the nature of cohabitation, not just marital status, matters for suicide risk in men
The authors note the need for 'interpreting the influence of social support by gender'
Finding highlights a distinction between marital status and actual social cohabitation as risk/protective factors
Results
Elevated creatinine levels were strongly associated with suicidal ideation in women with type 2 diabetes.
AOR for elevated creatinine in women = 11.69
289 (41.6%) of participants were women
Creatinine data were obtained from electronic health records
Elevated creatinine may indicate kidney dysfunction, a known complication of type 2 diabetes
Results
Smoking was strongly associated with suicidal ideation in women with type 2 diabetes.
AOR for smoking in women = 10.84
Smoking was not identified as a significant factor in men in this study
This represents a sex-specific psychosocial and behavioral risk factor
Clinical and behavioral data were obtained from electronic health records and self-reported questionnaires
Results
Higher fatigue was consistently associated with suicidal ideation in both men and women with type 2 diabetes.
AOR for fatigue in men = 1.44
AOR for fatigue in women = 1.43
Fatigue was assessed using self-reported questionnaires
The authors describe fatigue as 'a consistently associated factor of suicidal ideation' across both sexes
Authors conclude that 'fatigue management is crucial for the prevention of suicide among individuals with T2D'
Conclusions
The study identified distinct sex-specific profiles of suicidal ideation risk factors among adults with type 2 diabetes.
In men, key factors were marital status (AOR = 4.54), living arrangement (AOR = 0.16), and fatigue (AOR = 1.44)
In women, key factors were creatinine (AOR = 11.69), smoking (AOR = 10.84), and fatigue (AOR = 1.43)
Study was conducted between May 2022 and April 2023 at a university hospital outpatient clinic
Authors highlight 'the need for tailored suicide risk screening and for interpreting the influence of social support by gender'
What This Means
This research suggests that the risk factors for suicidal thoughts among people with type 2 diabetes differ meaningfully between men and women. In a study of 695 adults with type 2 diabetes, men who were married had higher odds of reporting suicidal ideation, while men who lived with others (regardless of marital status) had much lower odds—suggesting that the quality or type of social connection matters more than marital status alone. For women, having elevated creatinine levels (a marker of kidney problems) and being a smoker were each strongly associated with suicidal ideation. Fatigue was a shared risk factor across both sexes, with similar strength of association in men and women.
These findings matter because they challenge a one-size-fits-all approach to mental health screening in diabetes care. The fact that marriage appeared as a risk factor for men—while living with someone appeared protective—points to the complexity of social relationships and their effects on mental health. For women, the link between kidney health markers and suicidal ideation suggests that biological complications of diabetes may intersect with mental health risk in ways that are not yet fully understood.
This research suggests that healthcare providers caring for people with type 2 diabetes should consider both sex-specific biological factors (like kidney function in women) and psychosocial factors (like living situation in men) when assessing suicide risk. The consistent role of fatigue in both sexes also points to fatigue management as a potentially important component of mental health care for this population.
