According to the study, adults, children and adolescents living in the city have higher exposure rates. A summary of key survey data includes an assessment of residents' mental health. The mental health assessment included questions about the medical diagnosis of some conditions. Among adults, when asked about a diagnosis of depression, the percentage was 22,5%, a number higher than the 10,2% reported by the Brazilian adult population during the 2019 PNS. The diagnosis of anxiety or sleep problems was reported by 33,4% of respondents over 18 years of age. Among adolescents, 10,4% reported a medical diagnosis of depression and 20,1% of anxiety.
The application of the scales to people over 18 years old showed that 29,4% had a depressive episode and 19,2% had an anxiety disorder. Among adolescents, the application of the scales showed prevalence rates of 28,2% for depressive episodes and 15,6% for anxiety disorders.
