Q3Background:Associations between mental health anddermatology have generated a new branch of study calledpsychodermatology, which includes relevant conditions tothe adolescent population. However, there is limitedresearch focusing on this field and this specific population.Objective:To estimate the prevalence of dermatologicalpathologies in the Colombian adolescent population andtheir possible associations with mental health conditions.Methods:We performed a secondary analysis of theColombian National Mental Health Survey results. Arepresentative sample of the adolescent Colombian popu-lation answered questions regarding dermatological con-ditions and mental health disorders. We estimated theprevalence and evaluated associations using the chisquared independence test.Results:Of 1753 adolescents, 8.3% (CI95%=[6.8–10.1])had dermatitis or skin allergies and 4.5% (CI95%=[3.3–6.1])acne. For dermatitis, we found associations with age, ed-ucation, and family dysfunction (p-Values=0.024; <0.001;0.046 respectively). Acne was associated with age, sex,educational level, the number of social groups involved in,alcohol consumption, psychoactive substances use andprevious violent experiences (respective p-Values=0.007;0.004; 0.005; 0.036; 0.002; 0.003; 0.044). Regardingmental health, dermatological conditions were associatedwith depression, affective disorders, suicide attempt andsuicide ideation.Conclusion:Our results are the first to describe the prev-alence of these disorders in Colombia. This is an explor-atory study; nonetheless, it is of great value since it is thefirst to describe these associations in adolescents in amiddle-income country, which should be considered dur-ing clinical examinations. Further longitudinal studiesevaluating possible causal relationship between psychi-atric and dermatological conditions are fundamental toestablish causal links
