摘要：AbstractPoor health habits in adolescents seem to affect their optimal academic performance; the possible effect associated behaviour patterns may be added to this. A group of secondary students was assessed, by means of the GSHS, CACIA and the CARAS-R, comparing data obtained with results from the subjects of Mathematics and Language. From the different correlations gathered, those linking age with alcohol and drug consumption and higher body mass index are to be emphatised; academic performance with better nutrition, hygiene and effectiveness of attention along with a lower alcohol and drug consumption rates; proper eating habits with best results define self-control behaviour. On the other hand, the negative effect of alcohol on several dimensions analised is to be mentioned as well as the relation of the construct “reward delay” with more appropriate habits that favour health.
