Objectives: To study the prevalence of psychiatric disorders in adolescents with and without type 1 diabetes, the factors associated with its presence, and to test the reliability of a screening tool for use in clinical settings. Methods: Eighty-one adolescents were enrolled in this case-control study, including 36 diabetic participants and 45 controls. Clinical and sociodemographic data were collected and psychiatric symptoms and diagnoses were obtained from adolescents and their parents using a screening tool (Strengths & Difficulties Questionnaire) and a semi-structured interview (Development and Well-Being Assessment). Results: Psychiatric disorders were identified in 22.2% of the sample (30.56% among diabetic adolescents vs. 15.56% of controls: OR = 2.39, 95%CI 0.82-6.99; p = 0.11). Overweight (body mass index percentile X 85) was the only factor associated with psychiatric disorder (OR = 3.07; 95%CI 1.03-9.14; p = 0.04). Compared to the semi-structured interview, the screening instrument showed 80% sensitivity, 96% specificity, 88.9% positive predictive value and 92.3% negative predictive value for the presence of psychiatric diagnoses in adolescents. Conclusion: Psychiatric morbidity was high in this sample of adolescents, especially among those with diabetes. Routine use of the Strengths and Difficulties Questionnaire can help with early detection of psychiatric disorders in this at-risk group.
Background
Body image concerns are prevalent among Brazilian adolescents and can lead to poor psychological and physical health. Yet, there is a scarcity of culturally-appropriate, evidence-based interventions that have been evaluated and made widely available. Chatbot technology (i.e., software that mimics written or spoken human speech) offers an innovative method to increase the scalability of mental health interventions for adolescents. The present protocol outlines the co-creation and evaluation of a body image chatbot for Brazilian adolescents via a partnership between academics, industry organisations and the United Nations Children’s Fund (UNICEF).
Methods
A two-armed fully remote randomised controlled trial will evaluate the chatbot’s effectiveness at improving body image and well-being. Adolescent girls and boys (N = 2800) aged 13–18 years recruited online will be randomly allocated (1:1) into either: 1) a body image chatbot or 2) an assessment-only control condition. Adolescents will engage with the chatbot over a 72-hour period on Facebook Messenger. Primary outcomes will assess the immediate and short-term impact of the chatbot on state- and trait-based body image, respectively. Secondary outcomes will include state- and trait-based affect, trait self-efficacy and treatment adherence.
Discussion
This research is the first to develop an evidence-informed body image chatbot for Brazilian adolescents, with the proposed efficacy trial aiming to provide support for accessible, scalable and cost-effective interventions that address disparities in body image prevalence and readily available resources.

Objective: To detect latent patterns of drug-related problems and their predictors among adolescents. Methods: A three-wave randomized controlled trial was conducted among 6,391 7th and 8th graders (51.02% girls) at 72 public schools in six Brazilian cities to evaluate the #Tamojunto school-based drug prevention program. Patterns of drug use and behavior problems were identified through latent class analysis, and logistic regression analyses were used to detect predictors of high-risk and low-risk groups. Results: Two groups were found that best explained the patterns of drug use and problem behaviors: high drug use/high problems and low drug use/low problems, representing 36.7 and 63.3% of the sample, respectively. No program effect was a determinant of the risk of belonging to these groups. Any reported problem behavior in the year preceding baseline assessment increased the likelihood of belonging to the high-risk group at the 21-month follow-up by 16 times. Alcohol use at baseline and female gender increased the likelihood of belonging to the high-risk group by 70%. Conclusion: Previous behavior problems and alcohol use were the strongest predictors of higher risk, suggesting that effective earlier interventions and early screening for alcohol use and behavioral problems are needed at schools, particularly for girls.

Objective
This study's main purpose is to evaluate factors associated with eating disorder (ED) symptoms among Brazilian adolescents.
Method
The sample consisted of 5,213 students, mean age 13.24 (SD ±0.01), in the eighth grade of 93 public schools from three Brazilian cities. Data were collected through an anonymous self‐report questionnaire, assessing: sociodemographics, use of alcohol, tobacco, illicit drugs, binge drinking, bullying, and ED symptoms. We used confirmatory factor analysis and multivariate linear regression.
Results
We found that high levels of bullying victimization, binge drinking and the use of unprescribed weight‐loss substances were associated with higher levels of ED symptoms to both genders. However, only among girls, the higher age (β = .10; 95% CI = 0.02; 0.17) and the use of illicit drugs (β = .21; 95% CI = 0.094; 0.34) were associated with increase in the ED symptoms.
Discussion
We demonstrate a significant association of ED symptoms with drug use and bullying, highlighting the importance of addressing these factors in the development of ED prevention strategies.
