Objective:To analyze the prevalence and factors associated with the co-occurrence of health
risk behaviors in adolescents.Methods:A cross-sectional study was performed with a sample of high school students from
state public schools in Pernambuco, Brazil (n=4207, 14-19 years
old). Data were obtained using a questionnaire. The co-occurrence of health risk
behaviors was established based on the sum of five behavioral risk factors (low
physical activity, sedentary behavior, low consumption of fruits/vegetables,
alcohol consumption and tobacco use). The independent variables were gender, age
group, time of day attending school, school size, maternal education, occupational
status, skin color, geographic region and place of residence. Data were analyzed
by ordinal logistic regression with proportional odds model.Results:Approximately 10% of adolescents were not exposed to health risk behaviors, while
58.5% reported being exposed to at least two health risk behaviors simultaneously.
There was a higher likelihood of co-occurrence of health risk behaviors among
adolescents in the older age group, with intermediate maternal education (9-11
years of schooling), and who reported living in the driest (semi-arid) region of
the state of Pernambuco. Adolescents who reported having a job and living in rural
areas had a lower likelihood of co-occurrence of risk behaviors.Conclusions:The findings suggest a high prevalence of co-occurrence of health risk behaviors
in this group of adolescents, with a higher chance in five subgroups (older age,
intermediate maternal education, the ones that reported not working, those living
in urban areas and in the driest region of the state).
