The participants were given a questionnaire to know their habits. The survey showed that 80.9 per cent of the active subjects said that they do not smoke, compared to 71.4pct of the non-active adolescents.
It revealed that 59.2pct of the adolescents were physically active, with 71.1 pct of the boys as against 46.7 pct of the girls.
Moreover, 15pct of the adolescents were regular smokers, slightly more girls than boys.
