Résumé

Background: Smoking and alcohol use are risky behaviors that can start early in life. Aim: To determine the lifetime prevalence of tobacco and alcohol use in adolescents aged 10 to 14 years and related factors. Subjects and Methods: A survey about smoking and alcohol use was answered by 1,392 teenagers aged 10 to 14 years (46% women) from seven schools in a small city near Santiago. Personal, family, and school factors were evaluated through self-report scales. Smoking and alcohol use, as dichotomous dependent variables, were defined as having consumed any of these substances throughout life. Prevalence was calculated as percentages with 95% confidence intervals. Association analyses were conducted using multivariable logistic regression models. Results: Six and eleven percent of participants reported having smoked and used alcohol in their life, respectively. Smoking was associated with age, having behavioral problems, mothers’ smoking, perceiving that parents had drug problems, and not living with both parents. Alcohol use was mainly associated with age, having behavioral problems, perceiving that other students consumed drugs, alcohol use by both parents, and perceiving a lack of family support. Conclusions: Tobacco and alcohol use is highly prevalent in adolescents aged 10-14 years. There were common risk factors for smoking and alcohol use such as age and having behavioral problems, while other factors were more specific such as mothers’ smoking, or parental alcohol use.

Résumé

Background: Health-promoting behaviors are important to prevent diseases and prolong life in the population. People develop these behaviors throughout life. However, better benefits for health are obtained with an early development. Aim: To determine the prevalence of health-promoting behaviors among early adolescents and its associated factors. Material and Methods: Cross-sectional survey performed in 1,465 students of high, medium and low socio-economic status, attending fifth to eighth grades of schools located in a small Chilean city. Participants answered a questionnaire that gathered information about frequency of health-promoting behaviors such as health responsibility and nutrition, physical exercise and stress management, life appreciation, social support and different personal, school and familial factors. Results: A higher frequency of health-promoting behaviors was associated with better academic achievement, better school commitment, and higher perception of school membership. It also was associated with a better perception of health status and a higher conformity with physical appearance. Conclusions: Health promoting behaviors in these children are related to a better academic achievement and a higher integration with school environment.
