Substance Use as a Strong Predictor of Poor Academic Achievement among University Students.

BACKGROUND

Substance use is a growing concern globally and its association with students' academic performance is not well studied.

OBJECTIVE

This study was aimed to assess the prevalence of substance use (alcohol, tobacco, and khat) and its association with academic performance among university students.

METHODS

Cross-sectional study was conducted among Wolaita Sodo University students. A total of 747 students were selected by using cluster sampling technique. Data were collected by pretested self-administered questionnaire and examined using descriptive statistics and linear regression with 95% confidence intervals. Variables with value of less than 0.05 were considered as statistically significant.

RESULT

Prevalence of substance use (alcohol, tobacco, and khat) was 28.6%. Substance use (current smoking, chewing khat at least weekly, drinking alcohol on a daily basis, and having intimate friend who uses substance) was significantly and negatively associated with students' academic performance.

CONCLUSION

Substance use among Wolaita Sodo University students was as common as other studies in Sub-Saharan countries and negatively associated with students' academic achievement. The common practice of substance use and its association with poor academic performance demand the universities to have a good control of substance and to implement youth friendly activities.
