Manzar MD, et al. – This research was planned to study the sleep correlates of substance use in community-dwelling Ethiopian adults. According to the findings obtained, sleep correlates of substance use were found in community-dwelling Ethiopians. These findings could help in the development of targeted strategies to manage substance use-related sleep disturbances.

Methods

• Using simple random sampling, a cross-sectional study 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.
• Using binary logistic regression with substance use (khat, smoking, and alcohol), dichotomized sleep measures (sleep quality and sleep latency) evaluated by the Pittsburgh Sleep Quality Index (PSQI) were used in association analysis .

Results

• The study results showed that sleep latency was related to 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).
• Findings revealed that sleep quality was correlated 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).
