[Relationships between psychosocial risk behavior and the family in adolescents' from Suba, an urban area in Bogotá].

Objective: Assessing the relationship between adolescents' high-risk behaviour and family dynamics regarding structure and perception of family functionality.

Methodology: A cross-sectional, observational study was carried out on a population of 12,302 adolescents ranging in age from 10 to 19 years attending 12 public schools in the urban area of Suba (Bogota). A self-assessment questionnaire was administered, focusing on sexual behaviour, addiction, depression, violent behaviour and eating disorders.

Results: There was 63 % prevalence regarding good family function and 7 % prevalence concerning severe family dysfunction; comparing these with high-risk behaviour revealed a relationship with violent behaviour (4.1 OR, 3.4-4.7 95 %CI), eating disorders (2.3 OR, 1.9-2.8 95 %CI) and sexual relationships (2.0 OR, 1.7-2.4 95 %CI).

Conclusions: Family dysfunction was found to be more frequently associated with high-risk behaviour in adolescents from low socioeconomic strata in Bogota than that found to derive from family structure. The strongest relationship was observed between violence and family.
