Suicidal ideation (SI) serves as an important predictor of suicide. The prevalence of SI has increased following the COVID-19 pandemic. This study aims to investigate the prevalence and risk factors associated with SI after the pandemic in the Kerman province. This cross-sectional study was conducted in 23 counties of the Kerman province between 2021 and 2022. The Beck Scale for Suicidal Ideation (BSSI) was utilized to estimate SI, while multiple logistic regression analysis was employed to examine the impact of various variables on SI. A total of 1421 individuals (47.7% men, 50.0% women and 2.3% unknown) with an average age of 35.17±9.47 years participated in this study. The estimated prevalence rate of SI was 9.2%, with variations ranging from 0% to 42% across different counties. Individuals with SI exhibited a significantly younger mean age and fewer family members. Furthermore, SI was significantly more prevalent among single participants, unemployed individuals, students, those with a history of mental illness, prior psychiatric medication use, and previous SI. Employed individuals had 87% lower odds of experiencing SI compared to the unemployed. Individuals with a history of prior SI had 239 times higher odds of SI than those without such a history. Additionally, each year increase in age corresponded to an 8.8% decrease in the odds of SI. The high prevalence of SI is concerning, and it is essential to remain vigilant regarding its health and social consequences as the pandemic continues. Therefore, it is imperative to provide enhanced mental health services, particularly targeting at-risk groups.
