Another priority for future research is to characterize all of the risk factors and resources in immigrant populations and identify how they relate to each other and combine to affect health.117 Neglected risk factors include stressors and strains associated with migration and adaptation, inadequate health care in the country of origin and factors linked to larger social structures and context, such as institutional racism and interpersonal discrimination.117 For example, because of challenges to socioeconomic mobility for Mexican immigrants, increasing length of stay in the U.S. could reflect greater exposure to blocked opportunity and thwarted aspirations, which in turn could lead to growing levels of alienation and poorer health.118 A study of 1001 adult migrant Mexican workers in Fresno, CA assessed the association between stressors linked to acculturation and health.118 The three aspects of acculturation stress assessed were stressors linked to discrimination, legal status and problems speaking English. The study found that acculturation stressors were inversely related to self-reported measures of physical and mental health and partially accounted for the declines in these health indicators with years in the U.S. In
