Sleep Disorders in South-South Latino Migrants: The Role of Acculturation in the Subjective Assessment of Insomnia Symptoms.

Research on sleep disorders among migrant populations is limited, particularly in the context of south-south Latinos migrating to other Latin American countries. This study aims to analyze the effect that the acculturation process may play on the presence of the subjective assessment of insomnia symptoms in South American migrants in Chile. Under a cross-sectional design, 1844 South American migrants from Colombia, Venezuela and Peru, currently residing in Chile, were evaluated. Of these, 50% were women with an average age of 35 years. Data were collected using the Insomnia Severity Index (ISI), the EBEA scale for acculturation stress, a scale based on Berry's acculturation strategies, and the anxiety subscale of the DASS-21. Mediation models were employed to assess anxiety as a mediating variable between both acculturation stress and acculturation orientations as well as insomnia symptoms. A home-country-focused orientation was inversely related to insomnia symptoms, whereas a host-country-focused orientation showed a direct association. Anxiety did not mediate either of these relationships. However, acculturation stress was directly associated with the emergence of insomnia symptoms; in this relationship, anxiety partially mediated the negative effect of stress on sleep. There is a complex and dynamic interplay between the acculturation process, insomnia, and anxiety within south-to-south migration in Latin countries. Understanding these relationships could promote culturally sensitive interventions to mitigate the adverse effects of migration-related stressors on sleep health and the overall well-being of Latino migrants.
