   Abstract 

Background: There is a high risk of suicidal attempt in patients with depression. This risk varies according to the sociodemographic status and clinical presentation.
Aim: To assess the prevalence of suicidal ideation and attempt in patients with major depressive disorder, and to find the correlation between the two.
Methods: Sixty patients with major depressive disorder having suicidal ideation were recruited in the study. Of these, 10 had a history of suicidal attempt made in the past or current episode. Sociodemographic details were evaluated and the Hamilton Rating Scale for Depression (HAM-D) was administered.
Results: Analysis of the data showed that the incidence of suicidal attempt was 16.6% in patients with suicidal ideation. Statistically, a higher risk of suicidal attempt was found in individuals <30 years of age. Single men, married women and students were more likely to attempt suicide; higher education was also a vulnerability factor. Attempters scored significantly higher in severity of suicidal ideation, agitation and paranoid symptoms whereas among non-attempters, hypochondriasis and general somatic symptoms were more often present.
Conclusion: All patients expressing suicidal ideation do not attempt suicide. Young patients with depression, especially unmarried men, married women and students, having severe suicidal ideation with agitation or paranoid symptoms are more likely to attempt suicide.

   Introduction Top


Psychiatric patients who attempt suicide have greater suicidal ideation compared with patients who do not attempt suicide. [1] Suicidal ideation is present and appears to be a precondition for suicide attempts in patients with major depressive disorder. Sokero et al. [2] found that among 15% of those who had attempted suicide, the majority (95%) had suicidal ideation. Age, sex and education failed to distinguish between suicide attempters and non-attempters. [3] Srivastava et al. [4] found a positive correlation between suicide attempt and the severity of depression, male sex, being married, employed and < 35 years of age. Higher levels of suicidal ideation, aggression and hostility were reported in subjects who attempted suicide. [5]

The present study was carried out to see if there was a correlation between suicidal ideation and suicidal attempt in patients with major depressive disorder. The sociodemo­-graphic and clinical variables of the patients were also analysed.


   Methods Top


The study sample consisted of 60 patients (31 men and 29 women) attending the Psychiatry Outpatient Department of the Institute of Medical Sciences, Banaras Hindu Universty, Varanasi from June to November 2004. Patients between 16 and 60 years of age who presented for treatment of a major depressive episode and had suicidal ideation were included in the study. The mean age of the sample was 31.38±11.59 years. The exclusion criteria were current substance or alcohol abuse, neurological illness, active medical conditions, history of use of any psychotropic medication and other psychiatric illnesses. All patients underwent a physical examination and routine blood tests were done.

A semi-structured proforma was used to record the sociodemographic variables, and psychiatric and medical history of the patients. They were clinically assessed for depression. The severity of the major depressive episode was measured objectively using the Hamilton Rating Scale for Depression (HAM-D). [6] Diagnosis of the current depressive episode was based on the DSM-IV criteria. [7] Chi-square test was applied to test the association between the socio­demographic variables. Mean and standard deviation of different symptom variables of HAM-D were calculated. To test the statistical difference between the two groups, independent sample t test was applied. A value of p<0.05 was considered statistically significant whereas p>0.05 was considered statistically non-significant.

Sociodemographic profile

[Table 1] gives the sociodemographic profile of the patients. Among the 60 patients, 10 had attempted suicide (16.6%). However, no one more than 30 years of age had attempted suicide.

Thirty-four patient were from rural areas and 26 were from urban areas. More patients from urban areas attempted suicide compared with those from rural areas (23% vs. 11.8%). Forty­four patients were married (73.3%); among them, 7 had attempted suicide (15.9%). Of the 16 unmarried patients (26.6%), 3 had attempted suicide (18.7%) and all of them were men.

Thirty-nine patients (65%) had studied up to or higher than class 10. Among these, 9 patients had attempted suicide (23%). On the other hand, only 1 patient (4.8%) had attempted suicide among those who were educated below the level of class 10 (21 [35%]).

Twenty-four patients were housewives (40%), 15 were students (25%) and 21 were either self-employed, government employees, farmers or unemployed (35%). Students were the most vulnerable group for attempted suicide (26.6%), followed by housewives (16.7%) and those in the 'others' category (9.5%).

[Table 2] gives the psychiatric history of attempters and non­-attempters.

Clinical characteristics

[Table 3] compares the clinical characteristics of attempters with non-attempters based on the HAM-D. The mean and standard deviation (SD) of symptom variables in HAM-D were calculated for the two groups. The two groups were compared using the t test. The intensity of suicidal thoughts, agitation and paranoid symptoms were more in attempters, whereas general somatic symptoms and hypochondriasis were more in non-attempters. The difference between attempters and non-attempters on other variables was statistically not significant.


   Discussion Top


In this study, the incidence of suicidal attempt was 16.6% in patients with a major depressive episode and suicidal ideation, which is comparable to that reported by Sokero et al. [2] (15%).

All the attempters were <30 years of age. This is comparable to the study by Narang et al. [8] where 73% of the attempters were <30 years of age. Kessler et al. [9] reported that age <25 years is a significant risk factor for suicidal attempt among those with suicidal ideation. However, to get a more comprehensive trend in this area, a study with a much larger sample should be conducted.

No significant difference was found between male and female attempters, which is in concurrence with the findings of other Indian studies. [10] However, Kessler et al. [9] found that more women were at risk for suicidal attempt and suicidal ideation.

In this study, the representation from rural areas was higher compared with urban areas, but a higher number of patients from the urban background attempted suicide, which is comparable to the findings of Narang et al. [8]

Another finding of this study was that a higher number of single men and married women attempted suicide compared with married men and unmarried women. This finding was in concurrence with that reported in previous studies. [8],[11],[12],[13]

It was observed that patients in the more educated group were more likely to attempt suicide. However, Kessler et al. [9] found that poorly educated subjects were more vulnerable to suicidal attempts. Among attempters, students and housewives outnumbered the 'others' group, which is in concurrence with the study by Narang et al. [8]

Malone et al. [5] reported a higher level of suicidal ideation, aggression, hostility and impulsivity in subjects who attempted suicide. This was also observed in the present study where attempters had a higher level of suicidal ideation and agitation. Malone et al., however, did not find any correlation between suicidal attempt and paranoid symptoms. Srivastava et al. [4] also reported a low positive relationship between severity of depression and suicidal intent. Botswick et al. [14] also reported that impulsivity, aggression and psychosis increased in attempters. Roose et al. [15] concluded that delusional, depressed patients were five times more likely to commit suicide than non-delusional ones.


   Conclusion Top


All the patients who express suicidal ideation do not attempt suicide. Suicidal attempts were reported in only 16.6% of the patients with major depressive episodes having suicidal ideation. A significantly higher number of patients in the age group of <30 years attempted suicide. Intensity of suicidal thoughts, agitation and paranoid symptoms were more in attempters, whereas general somatic symptoms and hypochondriasis were more in non-attempters. Young patients with depression, especially unmarried men, housewives, students and those with class 10 or higher education, having severe suicidal ideation with agitation or paranoid symptoms are more prone to attempt suicide.
