Objective. To verify the prevalence and associated factors of suicidal ideation among adolescents aged 11 to 15 years. Method: Cross-sectional population-based study. Adolescents completed a self-report that contained the Children's Depression Inventory. Suicidal ideation was measured according to item 9 of the Children's Depression Inventory. Multivariate logistic regression analysis was applied using a hierarchical model. Results: 1145 adolescents were invited to participate, and 1039 were interviewed (refusal rare: 9.26%). The prevalence of suicidal ideation was 14.1%. Factors associated to suicidal ideation: female gender, current alcohol consumption, use of illicit drugs, symptoms indicating conduct disorders and high Children's Depression Inventory scores for depressive symptoms. Conclusion: Prevention strategies should focus on female adolescents, especially those sexually active with probable mental health problems and substance use. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the serum leptin levels in cannabis smokers. Methods: This was a cross-sectional population-based study of participants between the ages of 18 and 35 years. The data were collected through a self-administered questionnaire covering sociodemographic data and the use of psychoactive substances. Leptin levels were measured using a commercial ELISA kit. Results: Of the 911 participants, 6.7% were identified as cannabis smokers and had significantly lower leptin levels (p = 0.008). When stratified by gender, there was a significant decrease in leptin levels among male smokers (p = 0.039). Conclusion: Cannabis smoking was linked to leptin levels in men, suggesting that the response to biological signals may be different between men and women. [ABSTRACT FROM AUTHOR]
