Abstract

Purpose

The relationship between sleep disturbances and substance use can have harmful effects. Evidence shows widespread use of substances, including khat, in the Ethiopian population. However, to the best of our knowledge, no study has investigated the sleep correlates of substance use in community-dwelling Ethiopian adults.

Materials and methods

A cross-sectional study using simple random sampling was performed on community-dwelling adults (n = 371, age = 25.5 ± 5.7 years, body mass index = 22.0 ± 2.2 kg/m2) in Mizan-Aman, Ethiopia. Dichotomized sleep measures (sleep quality and sleep latency) assessed by the Pittsburgh Sleep Quality Index (PSQI) were used in association analysis using binary logistic regression with substance use (khat, smoking, and alcohol).

Result

Sleep latency was associated with khat chewing (adjusted odds ratio (AOR) = 2.8, 95% confidence interval (CI) 1.7–4.4) and tobacco smoking (AOR = 2.1, 95% CI 1.4–3.0). Sleep quality was associated with khat chewing (AOR = 3.1, 95% CI 1.8–5.2), tobacco smoking (AOR = 1.7, 95% CI 1.2–2.5), and alcohol intake (AOR = 1.9, 95% CI 1.1–3.1).

Conclusion

Sleep correlates of substance use were found in community-dwelling Ethiopians. These findings may aid in the development of targeted strategies to manage substance use-related sleep disturbances.
