BackgroundSweden has welcomed migrants, but attitudes have shifted, becoming hostile due to populism and the growing number of migrants. This has left migrants feeling unwelcome and marginalized. Few studies have examined the extent to which migrants perceive discrimination, who, why, where and its relationships with different outcomes. This study has two aims: to assess the prevalence, reasons, and determinants of perceived discrimination among migrants (1) and its associations with self-rated health, sexual health, healthcare use, and integration (2).MethodsWe analysed data from a 2018 survey on migrants’ sexual and reproductive health and rights. The survey included 1740 migrants aged 16 or older. We used descriptive and log-binomial regression analyses to estimate prevalence, crude and adjusted prevalence ratios (APR) with 95% confidence interval (CI).ResultsAbout 36% of participants perceived discrimination in Sweden, with ethnic origin (62%) and religion (35%) as main reasons. Perceived discrimination occurred in public spaces (47%), schools (33%), internet (20%), work (19%), public services (18%), residential areas (16%), and healthcare settings (10%). Migrant men (APR: 1.26, CI:1.07–1.49), born in Middle East and North Africa (APR: 1.57, CI:1.26–1.95) and South Asia (APR: 1.61, CI:1.27–2.04) regions, with more than 12 years of education (APR: 1.33, CI:1.10–1.60), a non-heterosexual orientation (APR: 1.21, CI: 1.02–1.43), a non-Christian religion (APR: 1.41, CI: 1.10–1.80), economic stress (APR:1.67, CI: 1.44–1.93) or Swedish language skills (APR: 1.24, CI:1.07–1.43) perceived discrimination more than their counterparts. In contrast, the oldest participants (46 years or more) perceived less discrimination (APR:0.55, CI: 0.37–0.80) than the youngest ones (16–25 years). Moreover, perceived discrimination was associated with poor self-rated general (APR:1.72, CI: 1.45–2.04) and sexual health (APR:1.40, CI:1.2–1.64), integration (APR:1.25, CI:1.14–1.37), and healthcare access (APR: 1.48, 1.16–1.89).ConclusionsThis study shows that migrants in Sweden face widespread perceived discrimination based on ethnicity and religion. This can affect their health, healthcare use, and social integration. The study calls for policies and interventions that tackle systemic perceived discrimination, foster inclusion, and guarantee equal opportunities in accessing healthcare and resources for migrants. It also urges support for vulnerable groups who perceive more discrimination, such as migrants from certain regions or under economic stress.
