Objective To report the prevalence and trends of the BMI
of Portuguese adolescents in 2002, 2006 and 2010.
Methods 4138 boys and 4472 girls self-reported weight,
height, physical activity, perception of health and life
satisfaction.
Results For adolescents aged 11–13 years, the prevalence
of overweight/obesity decreased from 23.5 % in 2002 to
20.7 % in 2010, using IOTF cutoff points, and decreased
from 32.4 to 28.4 % between 2002 and 2010 using WHO
cutoff points. For adolescents aged 15–17 years, the
prevalence increased from 13.9 to 16.8 % between 2002
and 2010 using IOTF cutoff, and increased from 14.8 % in
2002 to 18.2 % in 2010 when using WHO cutoff points.
Although the prevalence decreased among younger adolescents
and increased among older ones, the differences
were not significant. Physical activity in the last 7 days
(p\0.05), better life satisfaction (p\0.05) and perception
of health (p\0.001) predicted lower body mass index
z score.
Conclusions Overall, there have been no significant
changes in overweight and obesity prevalence in Portuguese
adolescents from 2002 to 2010. However, the
prevalence remains high and therefore it is important to
continue surveillance.
