Relationship between psychoactive substance, alcohol and cigarette use in nursing students. A cross-sectional study

Background

The increase in the use of psychoactive substances, alcohol and cigarettes in young people has become a public health problem. The identification of factors that increase or reduce the risk of exposure to these substances and the possible relationship between them is essential for planning strategies with a risk approach; hence the reason for this study. The objective was to establish the profile of use of psychoactive substances, alcohol and cigarettes and the factors associated with such use in nursing students of a higher education institution.

Methods

Quantitative, observational, analytical cross-sectional study.

Results

We included 310 students from 1 st to 9th semester of a Nursing programme from a private higher education institution in Bogotá. The prevalence of psychoactive substance use in the last year was 2.96% (95%CI, 1.36−5.54), with marijuana being the substance most used (55.55%). The prevalence of alcohol and cigarette use during the last 12 months was estimated at 86.64% (95%CI, 83.24−91.0) and 12.16% (95%CI, 8.43–15.88) respectively. A statistically significant association was found between the use of these substances: alcohol use was associated with cigarette use (OR = 3.22; P = 0.006) and smoking was associated with psychoactive substance use (OR = 15.4; P < 0.001).

Conclusions

Alcohol use increases the likelihood of smoking cigarettes, and this in turn increases the likelihood of psychoactive substance use, in this university population.
