The aim of the current research is to ascertain any possible relationship that could exist between the alcohol consumption of the population and several sociodemographic variables, in addition to the influence of physical exercise/sports on the creation of healthy lifestyle habits. The sample comprised 1102 subjects from Almeria Spain, over 14 years of age, to whom we administered the "physical exercise/sporting habits and life styles" questionnaire, selecting the sections on physical exercise/sporting habits in leisure, fitness and state of health perception and alcohol consumption habits, related to attitudes, behavioural and sociodemographic variables. We used an innovative tool for data analysis in the sphere of physical exercise, known as the Bayesian networks, emphasizing a positive relationship between alcohol consumption and physical exercise/sporting activities, it being the active people, with an interest in physical exercise/sports, who have a good perception of their health and physical fitness who are the ones who make habitual and occasional use of this substance. The profile of the individual who does not drink alcohol is female, over 44 years of age, with no studies, housewives who have a poor perception of their health, and who do not do any physical exercise or plays sports, whereas the populations with health risks, are men between 15 and 44 years of age who have secondary school studies or a degree and who work in the public or private sector.
