Abstract
Alcohol-drinking is one of the most important public health problems related to an increase risk of
suicidal behaviors. The objectives of this cross-sectional analytical study were to determine the prevalence
and factors associated with suicidal ideation and suicide attempt in mental and behavioral disorder
due to use of alcohol. Subjects were 303 patients diagnosed with ICD-10 code F10.xx and admitted in
Suanprung Psychiatric Hospital during 1 October 2012 to 30 September 2013. Data of various factors were
collected from medical records. Results of the study revealed that prevalence of suicidal ideation and
suicide attempt were 22.4% and 5.0%, respectively. Factors significantly associated with suicidal ideation were having psychological comorbidities (adjusted OR = 2.58 95% CI; 1.14-5.85, p-value = 0.023), previous
suicidal ideation and previous suicide attempt (adjusted OR = 3.00 95% CI; 1.40-6.40, p-value = 0.004 and
4.27 95% CI; 2.31-8.94, p-value < 0.001, respectively), numbers of problems or life-events, more than 3 and
2 life events (adjusted OR = 4.36 95% CI; 1.53-12.41, p-value = 0.006 and 3.22 95% CI; 1.08-9.57, p-value =
0.036, respectively), and patients who drank 40 degree-rice clear liquor (adjusted OR = 3.10 95% CI; 1.33-
7.20, p-value = 0.009). Regarding factors related to suicide attempt, it is found that previous suicide attempts
and psychological comorbidities were statistically significant associated with suicide attempts
(adjusted OR = 4.36 95% CI; 1.53-12.41, p-value = 0.006 and 3.22 95% CI; 1.08-9.57, p-value = 0.036, respectively).
In conclusion, close monitoring should be emphasized in patients who had problem associate
with alcohol drinking and had previous suicidal ideation or previous suicide attempt(s), particularly in
those with psychological comorbidity and had more than 2 life-events.
