This is one of the factors to consider in the implementation of interventions that favour the use of ICTs&#44; which encourages sedentary habits and as a result may promote an increase in childhood obesity and related problems&#46;<a class="elsevierStyleCrossRefs" href="#bib0195"><span class="elsevierStyleSup">14&#44;15</span></a> Our study did not find an association between sedentary behaviour and household education level&#44; although these factors should be taken into account in future studies and when interventions are implemented&#46;</p><p id="par0105" class="elsevierStylePara elsevierViewall">On the other hand&#44; while the results of the bivariate analysis show that younger children are more inclined to use the Internet for health-related purposes&#44; these results were not confirmed by the multivariate analysis&#46;</p><p id="par0110" class="elsevierStylePara elsevierViewall">One of the most important barriers to the spread and use of the Internet for the administration of health questionnaires and communication with health services is the lack of Internet access and social inequalities in access&#46; However&#44; a recent study showed that the penetration of the Internet in the 14- to 19-year-old population in Spain is of 83&#46;7&#37;&#44; although there is a gradient associated with social class&#46;<a class="elsevierStyleCrossRef" href="#bib0205"><span class="elsevierStyleSup">16</span></a> Meanwhile&#44; data from the Instituto Nacional de Estad&#237;stica &#40;National Institute of Statistics&#41; for 2013 showed that 68&#46;9&#37; of households and 91&#37; of the individuals 10&#8211;15 years of age used the Internet&#46;<a class="elsevierStyleCrossRef" href="#bib0210"><span class="elsevierStyleSup">17</span></a> Finally&#44; in the population of schoolchildren&#44; computer rooms in Spanish primary and secondary schools provide Internet access to students&#46;</p><p id="par0115" class="elsevierStylePara elsevierViewall">The factors that influenced the willingness to use the Internet to communicate with health care professionals were a better self-perceived health-related quality of life and not reporting sedentary habits&#46; Although we could not establish the directionality of the association because the study had a cross-sectional design&#44; any intervention in this population should take this factor into account&#46; The inverse care law could be at play&#44;<a class="elsevierStyleCrossRefs" href="#bib0215"><span class="elsevierStyleSup">18&#44;19</span></a> with individuals that take the most advantage of health promotion using this or other media being those that need it least&#44; for instance those with a better self-perceived health and reporting better habits&#44; so that implemented interventions may actually increase health inequalities&#46;</p><p id="par0120" class="elsevierStylePara elsevierViewall">A few previous studies have investigated strategies to increase exposure to Internet and to online contents concerned with health-promotion&#46;<a class="elsevierStyleCrossRef" href="#bib0225"><span class="elsevierStyleSup">20</span></a> It is also necessary that we take into account the potential dangers and adverse effects of ICTs in this age group&#46; Cyberbullying seems to have increased along with Internet use&#46; The literature has described its negative impact on mental health&#44;<a class="elsevierStyleCrossRef" href="#bib0230"><span class="elsevierStyleSup">21</span></a> isolation from family or sedentary behaviours as mentioned above&#46; Thus&#44; it is advisable that preventive strategies be implemented along with the planned intervention&#46;</p><p id="par0125" class="elsevierStylePara elsevierViewall">One of the limitations of this study is that the validity of the responses to the questionnaire has never been assessed&#46; However&#44; most of its items are based on a previous questionnaire that&#44; while developed in a different context&#44; has shown an acceptable feasibility and discriminatory power&#46;<a class="elsevierStyleCrossRef" href="#bib0170"><span class="elsevierStyleSup">9</span></a> Furthermore&#44; the results of the study also supported the validity of the questionnaire&#46; A second limitation is that it is difficult to generalise our results since this is one of the first studies that analyses preferences and attitudes on Internet use&#46; More research is needed on different populations to strengthen our results on the use of ICTs&#46; Nevertheless&#44; the fact that we included all students in Palafolls&#44; a population with broad variability in its sociodemographic characteristics and that there was a high level of participation reinforces the representativeness of the findings&#46; Thirdly&#44; we did not analyse the potential adverse effects of the use of the Internet and ICTs overall&#44; which should be the subject of future research&#46; Fourth of all&#44; in this study the digital questionnaires were administered in the computers in the schools&#8217; computer rooms&#44; and we did not attempt administration through other devices such as tablets or smart phones that may be even more appealing to the population under study&#46; This aspect should be analysed in future studies to compare these modes of completion and the preferences of the surveyed individuals&#46; Lastly&#44; our study did not include the preferences and attitudes of the parents&#44; which may be exert a significant influence as a facilitating factor&#44; especially when it comes to health-related use&#46;</p><p id="par0130" class="elsevierStylePara elsevierViewall">Future studies on the use of the Internet in children and adolescents should assess its potential usefulness in everyday clinical practise&#44;<a class="elsevierStyleCrossRef" href="#bib0235"><span class="elsevierStyleSup">22</span></a> health promotion<a class="elsevierStyleCrossRef" href="#bib0240"><span class="elsevierStyleSup">23</span></a> and patient&#8211;doctor communication&#46;<a class="elsevierStyleCrossRef" href="#bib0245"><span class="elsevierStyleSup">24</span></a> ICTs can play an essential role in health care management and improvement&#44; especially for patients with chronic diseases&#46;<a class="elsevierStyleCrossRef" href="#bib0250"><span class="elsevierStyleSup">25</span></a> Our study did not find differences in the search for health information in students reported by parents to have a chronic disease&#46; This may be due to the fact that we studied a sample of healthy students&#46; On the other hand&#44; the clinical diagnoses determined by parental reporting of chronic conditions through the family questionnaire may not be consistently valid&#46; Furthermore&#44; if research confirms that the Internet can be used to improve doctor&#8211;patient communication in paediatrics and promote health knowledge and healthy habits&#44; the Internet could become a basic tool in everyday paediatric clinical practise&#46;</p><p id="par0135" class="elsevierStylePara elsevierViewall">In short&#44; the use of the Internet in the paediatric age group for data collection and health promotion is very promising&#46; However&#44; it must be taken into account that younger children seem more inclined to complete questionnaires online than older adolescents&#46; Internet use for communication and social activities is quite widespread&#44; both in males and females&#44; but its use for searching health information and communicating with health providers is scarce&#46;</p></span><span id="sec0035" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0095">Funding</span><p id="par0140" class="elsevierStylePara elsevierViewall">The study was funded by the <span class="elsevierStyleGrantSponsor" id="gs1">Ministerio de Sanidad</span> &#40;Ministry of Health&#41;&#44;
