Disease burden among migrants in Morocco in 2021: A cross‑sectional study.

Background: Morocco, traditionally an emigration country, has evolved into not only a transit country to Europe but also a country of residence for an increasing number of migrants, with 102,400 migrants in 2019. This is due to its geographic location, the induced effects of its "African policy," and the various laws adopted by Moroccan legislators in recent years. The purpose of this study is to determine the prevalence of communicable and noncommunicable diseases among migrants such as Hepatitis C virus (HCV), human immunodeficiency virus (HIV), diabetes, and hypertension.

Methods: We conducted a cross-sectional study in Oujda, Morocco, between November and December 2021. Face-to-face interviews with enrolled migrants aged 18 years and over, present in Oujda and attending an association, were carried out to collect socio-demographic data, lifestyle behaviors, and clinical parameters. Diabetes and hypertension were the primary outcomes. The Pearson's chi-squared test and the student's t-test were used to assess the bivariate associations between primary outcomes and categorical and continuous variables. In a multivariate model, we adjusted for predictors that were significant (p-value ≤0.05) in bivariate analysis to estimate Adjusted Odd Ratios (AOR) and 95% confidence intervals (CI).

Results: There were 495 migrants enrolled, with a male/female ratio of two and an average age of 27.3±11.5 years (mean±standard deviation), ranging from 18 to 76 years. Hepatitis C virus, human immunodeficiency virus, diabetes, and hypertension were found in 1%, 0.2%, 3.8%, and 27.7% of the population, respectively. Family history of diabetes was a risk factor for diabetes in the Oujda migrant population, with an Adjusted Odds Ratio (AOR) of 5.36; CI% [1.23-23.28]. Age (AOR of 1.1; CI% [1.06-1.13]) and African origin (AOR of 3.07; CI% [1.06-8.92]) were identified as risk factors for hypertension.

Conclusion: Migrants in Oujda are healthy. The high prevalence of hypertension, as well as the presence of HCV and HIV positive cases, emphasizes the importance of routine screening for hypertension, HCV, and HIV in order to detect and treat these diseases as early as possible.
