Abstract
Background/Objectives: Data about metabolic syndrome (MS) in people who use drugs (PWUD) undergoing treatment for recovery are limited. We aimed to explore the extent of the MS and its predominant components and determinants in a sample of PWUD undergoing treatment for recovery through rehabilitation or opioid substitution treatment (OST) in Lebanon. Furthermore, we investigated the effect of each treatment modality on the MS; Methods: This was a cross-sectional study, in which demographics and treatment-related, nutritional, and biochemical data of the participants were collected. MS was defined according to the American Heart Association and the National Heart, Lung, and Blood Institute (AHA/NHLBI) criteria. Descriptive statistics were presented, and bivariate and multivariate analyses were conducted; Results: A total of 155 male subjects with the following characteristics were included: OST: n = 80; rehabilitation: n = 75; mean age: 32.53 ± 8.39 years; mean body mass index (BMI): 27.41 ± 4.99 Kg/m(2); mean duration of treatment: 18 months. More than half of the sample had low HDL-C (56.8%) and/or elevated blood pressure (51.6%), 42.9% had elevated WC, 21.9% had elevated TG, and 12.3% had elevated FBS. Furthermore, 7.2% of the sample had no components of the MS, 29.2% had one component, 40.9% had two components, 16.9% had three components, and 5.8% had four components. MS was identified in 22.7% of the sample. Higher age was associated with higher odds of being diagnosed with MS (OR = 1.072; 95% CI: 1.021-1.126), whereas higher duration of current treatment was associated with lower odds (OR = 0.969; 95% CI: 0.944-0.995); Conclusions: MS and its components are prevalent in PWUD undergoing treatment for recovery. Routine screening and preventive measures are essential to prevent metabolic syndrome, particularly among older people and treatment newcomers.
