The socio-demographic data of the studied group showed that there was no statistically significant relation between age and the risk of suicide in which the mean age of the patients in the study was 30.34 ± 10.78 years, which is close to that in a study in which the mean age was 36.3 years [15]. Seventy-one percent of the patients < 35 years of age, with decreasing frequency with increasing age, with patients older than 35 years of age representing 29% of the sample, which is in agreement with studies reporting suicide to be more among young individuals than the elderly [16].
There was a high percentage of suicide in the age group 15–44 years in studies carried out in Egypt [16]. Among Arabs, suicide was more in the age group 20–40 years [17].
There was no statistically significant difference between sex and the risk of attempted suicide in the study. The male-to-female ratio was 1.17:1, which is close to the results of studies that showed no major difference regarding gender [17, 18].
However, a higher predominance of suicide rates in males over suicide rates in females was found to be 3.2:1 in 1950, 3.6:1 in 1995, and expected to become 3.9:1 in 2020 [20].
The differences in male-to-female ratios can often be attributed to the use of more lethal suicide attempt methods, greater aggressiveness, and higher intent to die among men [20]. In contrast, women outnumbered men in terms of suicide attempts at a ratio of 2.2:1 [21].
In our study, 6% of the patients of the study at risk for suicide had high education with the highest risk of 79% for primary education; the group of patients with high education group had the lowest suicide risk with significant statistical difference P value = 0.000. A similar figure was found by [22]. Where the primary education group constituted 51.7% of their suicide cases, students showed the highest suicide risk (40%) [19].
Suicide mortality was also found to be more in the lower education group [18]. A higher suicide risk was found among those with primary to secondary level education and among students [23].
The influence of the level of education on suicide risk may be attributed to three different pathways. First, because those with a low education level cannot seek better jobs and accumulate material wealth, they may have a greater risk of suicide mortality because of lower job security and poor monetary conditions [24].
Second, education might have an independent effect on suicide, irrespective of occupation, and income [25]. Third, selection and recruitment into education might have an impact. Those with mental disorders and chronic severe illness as a proximal cause of suicide at younger ages might have left school without any qualification and might be less likely to have the opportunity for further education [23].
Among the study sample, 63 % were unemployed, whereas the other 37% were working; 10% were skilled workers, whereas the rest 27% were unskilled workers with significant statistical difference P value = 0.000. In other studies, it was found that unemployed suicide victims represented 53% of the study sample [26].
Manual workers and unemployed individuals are at the highest risk of suicide [18]. Being unemployed was associated with a twofold to threefold increased relative risk of death by suicide compared with being employed [27].
In the study sample, only 44% were married, whereas 56% of the patients were either single (48%), divorced, separated, or widowed (8%)with no significant difference P value = 0.062 This was not very different from a study in Bahrain, in which 58.6% of the patients were single and divorced [22].
As reported by [26], study where patients showed a higher tendency to be single (43%). This difference can be explained by the stigma of being divorced in the Arab world so they would prefer emotional separation and still married over the divorce.
Regarding the diagnosis in the studied sample, 61% had mood disorders, 41% of them had major depressive disorder (MDD), 16% had mood disorder bipolar I depressive episode, and 4% had mood disorder bipolar I manic episode. On the other hand, 24% of the patients had psychotic disorders, 12% of them had schizophrenia, 2% brief psychotic disorder, 9% schizoaffective disorder, and only 1% had schizophreniform disorder. Also 15% of our patients had substance-induced disorders.
This was consistent with study of [12] in which mood disorders were 57%, substance-induced disorders 8%, and psychotic disorders 27.3%. It was also consistent with other studies as in a study done by [22], who found that mood disorders were at higher risk for suicide than other psychiatric illnesses.
There were no cases diagnosed with mental disorders due to brain damage, anxiety disorders, or mental subnormality in this work as the studied sample were among inpatients in Assuit University Hospital in which there were no admitted cases with such diagnoses during the time frame of the study.
Patients having a psychiatric illness for more than 5 years have increased risk of suicidality [22].
In this study, we recruited 100 patients with 54 male patients and 46 female patients.
In patients with mood disorders, MDD (major depressive disorder) was highly significant among females (58.7%) P value = 0.001, also we found that MD. BP I mania (mood disorder, bipolar I mania) was slightly higher in females than males (6.5%, 1.9% respectively).
In contrast, MD. BPI depression (mood disorder, bipolar I depression) was higher in males than females (22.2%, 8.7% respectively). This is close to Arsenault-Lapierre who found that the risk of mood disorders, specifically, depressive disorders, is greater in female suicides, and whereas mood disorders represented 59.4 % of the female diagnoses and 47.4 % of the male diagnoses (P = 0.089) [28].
However, [29] reported that male gender is predominant in patients with bipolar disorder who attempt suicide. In patients with psychotic disorders, the results showed that schizoaffective disorder, brief psychotic disorder, and schizophrenia form and were slightly higher in females than males (13%, 4.3%, 2.2%, 5.6%, 0.0% respectively).
On the other hand, schizophrenia disorder was slightly higher among male patients than females (16.7%, 6.5% respectively).
This was close to [30] who found that in patients with psychosis the following risk factors for attempted suicide in the general community were being females.
All patients with tramadol-induced disorders were males with highly significant difference P value = 0.000
However, [31] found that young male SUD (substance-used disorder) patients may have psychosocial features associated with suicidality in common with female.
In the study sample, almost 35% of the patients did not have a history of previous suicidal attempts, whereas 65% had attempted suicide; 11% of suicide attempters were repeaters.
This was close to [32] in which 24.7% of the patients did not have a history of previous suicidal attempts, whereas 75.3% had attempted suicide; 50% of suicide attempters were repeaters.
Comparison of the frequencies of suicidal attempts between the patients showed that 81.5% of patients tried to commit suicide once, whereas 18.5% committed suicide twice and more. These results were similar to the findings of other studies which reflected that previous suicide attempts had a higher risk of suicidality [33].
A suicide attempt is a risk factor for completed suicide; the risk in individuals followed up for 5–37 years was 7–13% [34], roughly corresponding to a 30–40 times increased risk of death from suicide in those who had attempted suicide compared with the general population [35].
The present study shows that frequency of suicidal attempts in patients with multiple suicide attempts before this one was more in MDD (major depressive disorder), bipolar disorders followed by schizophrenia in which patients with MDD with multiple previous attempts before this one was (30.8%), bipolar disorders (23.1%), schizophrenia (16.9%), while patients with no previous attempts before this one were higher in MDD (60%), tramadol-induced depression (17.1%), followed by bipolar disorders (14.3%) with P value = 0.005.
This is to some extent consistent with [35] who postulated that the rates of suicide after a previous suicide attempt were particularly increased among men and women with schizophrenia or bipolar and unipolar disorder. Population attributable fractions, expressing the impact of coexistent psychiatric disorder on suicide in people who had previously attempted suicide, suggested a modest but significant impact for other depression in women, schizophrenia in men, and bipolar and unipolar disorder in both sexes.
This also is close to Virkkunen 1974 [36] who reported that the life-time frequency of suicide attempts was high (between 23% and 42%) for all categories of psychotic disorders, with the exception of schizophreniform disorder. Although the risk of suicide is highest during the first 10 years of schizophrenia [36].
In this study, it was found that violent suicidal methods constituted 67% of the suicidal methods used; cutting of wrists was the most commonly used violent method, used by almost 24% of the patients, a number similar to another study that found that 25% of the patients had attempted to cut their wrists [15]. Also, cutting of wrists was found to be the most common violent method [37], followed by hanging (20%). This is not consistent with Guwaili [15], it was only 3%. Only 4% of suicide attempts were made by burning, whereas another study in Egypt found that among violent methods 36% of patients attempted suicide by burning [15].
Drug overdose was the most commonly used nonviolent method (18%), followed by poison intake (10%); self-poisoning by a drug overdose or poison ingestion represented 80% of the nonviolent suicide methods [15]. Overdose by tablet ingestion was the most commonly used method in nonviolent suicide attempts (80%) [38].
A study in Lebanon found that about 95% of individuals who attempted suicide used self-poisoning [37]. Most individuals (77% men, 90% women) used self-poisoning in their suicide attempts [39]. This can be attributed to easy accessibility and availability of poisons and over-the-counter drugs in Egypt.
Our study also found that patients used violent methods was slightly higher in MDD (44.8%), bipolar disorders (16.4%) followed by schizophrenia (14.9%) while the nonviolent methods were slightly higher in MDD (33.3%), bipolar disorders (27.3%) followed by schizoaffective disorder (18.2%).
Suicidal intent factor was higher in psychotic disorders 29.21 ± 2.96 which was a significant difference in comparison to mood disorders and substance-induced disorders (P value = 0.002), the same was found in total score of pre Sheehan suicidality tracking scale (pre S-STS) which was 40.79 ± 6.73 in psychotic disorders with (P value = 0.009). This showed its impact on treatment outcome evaluated by post Sheehan suicidality tracking scale (post S-STS) as the score for suicidal intent factor was 3.71 ± 1.78 in psychotic disorders with (P value = 0.027) in comparison to mood disorders and substance-induced disorders, post Sheehan suicidality tracking scale (post S-STS) score was 3.71 ± 1.78 with (P value = 0.018), this means a marked improvement in treatment, but treatment outcome was better in mood and substance-induced disorders in comparison to psychotic disorders; this was consistent with [13, 21] who found a high risk for suicide in schizophrenia, schizotypal, and delusional disorders [40].
Disability was higher in psychotic disorders evaluated by disability rating scale (DRS) in which (P value = 0.000) which can be explained by the severity of psychotic disorders [41].
