Abstract

Background: Suicide in schizophrenia is a serious problem--ideation rates go up to 40%, and approximately one half of patients attempt suicide at least once. The distinction between attempters and ideators is vital in everyday clinical practice., Aim: To explore the association between psychopathology and suicidal behavior in a comparative study of three groups of patients with schizophrenia: suicide ideators, suicide attempters, and subjects without suicide ideation and behavior., Method: The study included 509 patients: suicide attempters (n = 159), ideators (n = 180), and a comparative group (n = 170). The clinical assessment consisted of a structured psychiatric interview and an evaluation of sociodemographics, suicidality (SIBQ), psychopathology (PANSS), and depression (CDSS)., Results: Suicide attempters were more depressed than ideators, and both groups had higher CDSS scores than the comparative group. The overall contribution of positive, negative, and general PANSS symptoms was not statistically significant enough to differentiate ideators from attempters. A principal component analysis of the PANSS items revealed five components: disinhibition, withdrawal, anxiety and guilt, reality distortion, and disorganization. Two logistic regression analyses showed that suicide ideation or attempt was significantly related to depression, anxiety, guilt, gender, age, and number of previous hospitalizations. Compared to suicide ideators, attempters were more depressed, had a higher number of previous hospitalizations, and lower education., Conclusion: The results indicate that clinicians should look for depression, anxiety, and guilt feelings, while positive and negative symptoms seem to be less relevant for suicide assessment in schizophrenia.

Abstract

Background-\ud \ud The aim of the present study was to investigate associations between food insecurity with suicidal ideation and suicide attempts in adults aged ≥50 years from six low- and middle-income countries (LMICs).\ud \ud Methods-\ud \ud Cross-sectional, community-based data from the World Health Organisation's Study on Global Aging and Adult Health were analyzed. Self-reported information on past 12-month suicidal ideation and suicide attempts was collected. Past 12-month food insecurity was assessed with two questions on frequency of eating less and hunger due to lack of food. Multivariable logistic regression analysis was conducted to assess the association between food insecurity and suicidal ideation or suicide attempts.\ud \ud Results-\ud \ud The final analytical sample included 34,129 individuals aged ≥50 years [mean (SD) age 62.4 (16.0) years; 52.1% females]. Compared to no food insecurity, severe food insecurity was associated with a significant 2.78 (95%CI = 1.73–4.45) times higher odds for suicidal ideation, while moderate and severe food insecurity were associated with 2.59 (95%CI = 1.35–4.97) and 5.15 (95%CI = 2.52–10.53) times higher odds for suicide attempts, respectively.\ud \ud Limitations-\ud \ud The cross-sectional design, the use of self-reported wish to die as a measure of suicide ideation, and that suicidal ideation and suicide attempts were only assessed among those who had depressive symptoms, could be considered limitations of our study.\ud \ud Conclusions-\ud \ud Food insecurity was positively associated with suicidal ideation and suicide attempts. Targeting food insecurity among older adults in LMICs may lead to reduction in suicidal ideation and suicide attempts, although future longitudinal studies are warranted to confirm this.
