  This study shows the feasibility of an eHealth solution for tackling eating
habits and physical activity in the adolescent population. The participants
were children from 11 to 15 years old. An intervention was carried out on 139
students in the intervention group and 91 students in the control group, in two
schools during 14 weeks. The intervention group had access to the web through a
user account and a password. They were able to create friendship relationships,
post comments, give likes and interact with other users, as well as receive
notifications and information about nutrition and physical activity on a daily
basis and get (virtual) rewards for improving their habits. The control group
did not have access to any of these features. The homogeneity of the samples in
terms of gender, age, body mass index and initial health-related habits was
demonstrated. Pre- and post-measurements were collected through self-reports on
the application website. After applying multivariate analysis of variance, a
significant alteration in the age-adjusted body mass index percentile was
observed in the intervention group versus the control group, as well as in the
PAQ-A score and the KIDMED score. It can be concluded that eHealth
interventions can help to obtain healthy habits. More research is needed to
examine the effectiveness in achieving adherence to these new habits.
