One in ten patients with diabetes have suicidal thoughts after 1 year of the COVID-19 pandemic: We need to talk about diabetes and mental health not only during Suicide Prevention Awareness Month.

Suicide Prevention Awareness Month may have a special meaning for patients with diabetes in September 2021, almost 2 years after the onset of the COVID-19 pandemic. People living with diabetes are known to be at increased risk for mental health disorders. Compared to the general population, the prevalence of depression is two times higher among people with type 2 diabetes and three times higher among people with type 1 diabetes [1]. In usual situations, living with diabetes significantly increases the risk of suicide. The combined incidence rate of suicide in subjects with diabetes is 2.4/10,000 person-years, and the proportion of long-term deaths attributable to suicide is 7.7% in type 1 diabetes and 1.3% in those with type 2 diabetes [2].

Several studies have shown that the COVID-19 pandemic negatively affected mental health in people with diabetes. A study carried out by our group showed that 52.9% of patients with type 2 diabetes and 32.7% of those with type 1 diabetes had a positive screening for mental health disorders in the first 3 months of the pandemic in Brazil [3]. Diabetes-related emotional distress was also observed in 29.2% of these patients, eating disorders in 75.8%, and moderate/severe sleeping disorders in 77.5% in this same period [3]. The high prevalence of mental health disorders is an alert to the risk of suicide in these patients, who may find themselves emotionally fragile during the social distancing period.

We followed a group of patients with diabetes from two university centers in Southern Brazil during the COVID-19 pandemic and performed a cross-sectional analysis at the 18th month of pandemic. In total, 150 patients were included, with a mean age of 54.6 ± 13.9 years old and a mean diabetes duration of 21.2 ± 10.8 years. Mental health disorders were screened using the Self-Report Questionnaire (SRQ-20), a screening, instead of a diagnostic tool, designed to detect non-specific psychological distress, including suicidality [4]. After 18 months of pandemic, the screening for mental health disorders was positive in 46.7% of patients with type 2 diabetes and 41.4% of patients with type 1 diabetes. Alarmingly, 9.3% of participants reported thoughts about ending their own lives in the past month (13.3% in type 2 diabetes and 5.2% in type 1 diabetes). (Fig. 1)

In people with diabetes, the effects of the pandemic on mental health may be exacerbated by both the fear of being part of a high-risk group and because of the social distancing measures, which favor self-isolation and hinder access to health care [3]. The greater challenge in maintaining the usual diabetes care routine may result in additional concerns related to glycemic control, potentially generating more suffering for those patients. The financial repercussions of the pandemic may also lead to difficulty in obtaining supplies for the treatment of diabetes and maintaining a balanced and healthy diet, which are essential for good glycemic control.

The risk of suicide seems to be increased during the COVID-19 pandemic. People at greater risk of suicidal ideation require exceptional attention. In the insulin‐treated population, the situation is even more serious, as the patient has control of a potentially lethal drug. Health professionals must be aware of the vulnerability of this group, identifying potential risks and offering assistance when necessary. Strategies aimed at reducing mental health disorders should be prioritized in crises [5]. The vaccination campaign appears as “a light at the end of the tunnel” for the current situation. However, as long as the vaccine is not accessible to the entire population and the maintenance of distancing measures may still be necessary, we need to be attentive to identify and mitigate the risks of suicide in patients with diabetes.
