[The study of migrant and immigrant population from the syndemic point of view].

The study of health of migrant and immigrant populations is of particular interest and actual in recent years, and there is a lack of research assessing aspects of aging of permanently resident immigrants, chronic non-communicable diseases, multimorbidity, and study of second generations. This contribution proposes to describe the relationship between health and immigration and their association with frailty through the anthropological concept of syndemics. Syndemics represents a set of closely interconnected and mutually enhancing health problems, significantly influencing the overall health status of a population. This occurs within the context of a perpetual pattern of harmful social conditions. Among the syndemics described in the literature, the most interesting in this area is the one concerning the increased frailty due to the interaction among diabetes, depression, immigration, and social distress, called VIDDA (Violence, Immigration, Depression, Diabetes, and Abuse), first identified in Mexican immigrant women in the United States. The main limitation of using the syndemic approach to study the health of immigrant populations is the difficulty in moving from the anthropological, primarily qualitative approach to the epidemiological-quantitative approach. Despite this, the epidemiological study of immigrant populations could benefit from the syndemic approach, because it can better describe complex causal relationships and provide evidence for modification of the clinical approach.
