dc.description.abstract | Background:
Overweight and obesity among adolescents may have
consequences, with potentially lasting effects on health and health-related quality of
life (HRQoL). Excess weight is also associated with decreases in physical activity
and cardiorespiratory fitness. The aim of the current study was to investigate the
short-term effects of a 12-week Internet intervention in a primary care setting
intended to increase cardiorespiratory fitness and HRQoL among overweight and
obese adolescents.
Methods:
In this controlled trial, participants (13–15 years) were non-randomly
allocated to an intervention- or a control group. The intervention group received 12-
weeks access to an online program providing tailored physical activity counseling
based on principles from Self-determination Theory and Motivational Interviewing.
The control group received standard follow-up by the school nurses. The primary
outcome measure of cardiorespiratory fitness was determined using a shuttle run
test. The secondary outcomes: HRQoL, leisure time exercise, body image and self-
determined motivation for physical activity and exercise, were assessed by self-
report measures. Age- and gender-adjusted body mass index (BMI) was calculated
based on measurements of height and weight. To compare pre-to post intervention
differences within groups, a paired samples t-test was used while crude differences
between groups were analyzed with an independent samples t-test.
Results:
Of the 120 participants, 108 completed the study, 75 in the intervention
group and 33 in the control group. Exposure to the intervention had a small effect on cardiorespiratory fitness (0.14; 95% CI [0.01;0.28];
P
5
0.04), and a moderate
effect on HRQoL (5.22; 95% CI [0.90; 9.53];
P
5
0.02). Moreover, the control group
increased significantly in BMI, yielding a moderate preventive effect on BMI (
2
0.39;
95% CI [
2
0.74;
2
0.03];
P
5
0.03) for the intervention group.
Conclusion:
The results suggest that the Internet intervention with tailored physical
activity counseling can have beneficial short-term effect on cardiorespiratory
fitness, HRQoL and BMI among adolescents with overweight and obesity. | en_US |
