Abstract

Due to the importance of alcoholism in Brazilian public health, this study was proposed to investigate the behavior of high school students concerning to the pattern of alcohol consumption in the city of Araraquara - SP, its association with socio-demographic variables and their spatial distribution considering the importance of early diagnosis for the implementation of public policies for prevention and treatment of this condition. It is an observational study of cross-sectional design. The sampling delineation will be the stratified probabilistic. The size of the sample was estimated by the process of sampling for a finite population, being estimated on 1,612 individuals. To identify the disorders concerning to alcohol, it will be used the survey AUDIT and its reduced versions (AUDIT-C e AUDIT-3).

It will be performed the descriptive statistic of the variables. To study the effectiveness of the detection of binge drinking, concerning to the use of different approaches on different methods, it will be estimated the sensibility, the specificity, the accuracy and the positive and negative preditive values of the tests. It also will be done the ROC curve and its area will be calculated. The association of binge drinking with each of the several variables of interest will be studied by the Ç2 test. The data that present statistic value or p<0,15 will make the multivaried analysis. The ominous-directional experimental semivariogram will be elaborated. The level of significance will be 5%.
