Abstract
The paper reports results of an analysis based on face-to-face interviews with two samples of Prague women aged 20-49: (1) a probabilistic sample (n = 718) of the Prague female population; and (2) a sample of 152 inpatients treated for substance dependence/abuse. Of the inpatients, 79% were diagnosed as alcohol dependent only, 15% as both alcohol dependent and drug dependent/abusers, 6% as drug dependent only. With very few exceptions, those with drug problems among the inpatients abused analgesics, hypnotics, or anxiolytics. With data obtained from the general population sample, two-stage hierarchical logistic regression was run with each of the eleven differently defined substance uses as dependent variables. Four demographic variables were entered as predictors into the regression equations in the first stage. From the seven potential risk factors of substance use statistically significant predictors were entered stepwise in stage two. The major result of the study is the specificity of the pattern of predictors related to each of the eleven considered substance uses. It is also found that in the general population the use of a particular substance is generally uncorrelated with the use of other substances. Alcohol use (even heavy alcohol use) has no relation to smoking, to the use of analgesics, hypnotics, anxiolytics--and is connected with a specific pattern of predictors.
