RESUMO
OBJECTIVE: The aim of our study was to identify and analyze selected factors influencing alcohol use among primary school children aged 8 to 15 years in the academic year 2009/10. METHODS: The sample consisted of children from 28 primary schools. Data of this cross-sectional study were collected using questionnaires. Chi-Square test was used to test differences in proportions of observed phenomena between boys and girls. Multiple logistic regression analysis was performed to identify the influence of selected factors on the variable "child's alcohol drinking per week". RESULTS: The sample consisted of 2,494 respondents (52% of boys, 48% of girls). In the study group 78% of all respondents (95% CI=76-80) drank alcohol infrequently (less than once a week) or did not drink alcohol at all, and 22% of respondents (95% Cl=20-24) drank alcohol at least once a week. More boys than girls considered alcoholic beverages such as beer, wine and spirit as quite easily available. We performed the model of multivariate logistic regression analysis using the independent variables: age of respondents, gender of respondents, mother's alcohol drinking, father's alcohol drinking, sibling's alcohol drinking, parental rules, parental control, and mental support from parents (if their children have problems) to identify their effect on the dependent variable - child's alcohol drinking per week. We found out that mother's alcohol drinking and a lack of mental support from parents did not have a statistically significant influence on child's alcohol drinking per week. CONCLUSION: The results of our study point to the fact that it is necessary to focus on the prevention of alcohol drinking in general and among school children in particular. We recommend greater control of the sale of alcoholic beverages, so as to prevent the purchase by people under 18 years of age.
