Objectives: Little is known about the dose–response
relationship between physical activity and health
benefits among young people. Our objective was to
analyse the association between the frequency of
undertaking moderate-to-vigorous physical activity
(MVPA) and the self-reported health status of the
adolescent population.
Design: Cross-sectional study.
Setting: All regions of Spain.
Participants: Students aged 11–18 years participating
in the Spanish Health Behaviour in School-aged
Children survey 2006. A total of 375 schools and
21 188 students were selected.
Main outcomes: The frequency of undertaking MVPA
was measured by a questionnaire, with the following
four health indicators: self-rated health, health
complaints, satisfaction with life and health-related
quality of life. Linear and logistic regression models
were used to analyse the association, adjusting for
potential confounding variables and the modelling of
the dose–response relationship.
Results: As the frequency of MVPA increased, the
association with health benefits was stronger. A linear
trend (p<0.05) was found for self-rated health and
health complaints in males and females and for
satisfaction with life among females; for health-related
quality of life this relationship was quadratic for both
sexes ( p<0.05). For self-reported health and health
complaints, the effect was found to be of greater
magnitude in males than in females and, in all scales,
the benefits were observed from the lowest frequencies
of MVPA, especially in males.
Conclusions: A protective effect of MVPA was found
in both sexes for the four health indicators studied,
and this activity had a gradient effect. Among males,
health benefits were detected from very low levels of
physical activity and the magnitude of the relationship
was greater than that for females.
