1 If your flask has not been used for some time, rinse with warm water to remove any residual odours. 2  DO NOT overfill your flask. Leave sufficient space in the neck to fit the stopper.  After filling, always ensure that both the outside cup and stopper are tightly closed.
The 8.4% prevalence of alcohol abuse/dependence estimated by the present study (13.1% for men and 4.1% for women) is above the average value of 6% that Galduroz et al8 (2003) found in a survey performed in 1999.
RESULTS: The estimated prevalence of alcohol abuse/dependence was 13.1% (95% CI: 8.4;19.9) in men and 4.1% (95% CI: 1.9;8.6) in women. In the final multiple logistic regression model, alcohol abuse/dependence was significantly associated with age, income, schooling, religion and illicit drug use.
