Objective:

To analyze the association between suicidal ideation and alcohol use in an adult population assisted in primary health care in Teresina, Piauí, Brazil, from June to September 2019.

Material and Method:

This is an observational, analytical and cross-sectional study conducted with 380 adults in 11 Basic Health Units. The source population consisted of 14,062 adults aged 20 to 59 years, registered in the e-SUS information system of the Family Health Teams. Data collection took place between June and September 2019, using a sociodemographic questionnaire, the Beck Scale for Suicide Ideation, and the Alcohol Use Disorders Identification Test.

Results:

The prevalence of suicidal ideation in the sample was 17.9%. Among these, 39.7% had clinically significant suicidal ideation. The prevalence of alcohol use by people with suicidal ideation was 42.6%, and 44.4% used alcohol among those with clinically significant suicidal ideation. There was an increase in the prevalence of suicidal ideation (33.3%) and clinically significant suicidal ideation (16.7%) in individuals with possible dependence. Those who did not have a partner were 1.4 times more likely to have suicidal ideation. Those with a history of discrimination were 1.9 times more likely to have suicidal ideation. Having a stressful event increased the chances of clinically significant suicidal ideation by 3.1 times and problems with sleep by 2.9 times.

Conclusion:

The study showed that alcohol use influenced suicidal ideation and clinically significant suicidal ideation in the sample.
