The study found that Mexican immigrants reported worse physical and mental health statuses than the other Latino immigrant groups. What provides the best explanation of this finding?

The finding that Mexican immigrants reported worse physical and mental health statuses compared to other Latino immigrant groups can be best explained by socioeconomic status (SES). Research consistently indicates that individuals with higher SES typically have better access to healthcare, healthier living conditions, and greater resources for stress management, all of which contribute to improved physical and mental health.

When focusing on the socioeconomic status of different Latino immigrant groups, it is likely that the average SES of Mexican immigrants is lower than that of other Latino immigrants. Lower SES can be associated with a range of negative outcomes, including financial instability, limited access to healthcare, and increased exposure to stressors that adversely affect health. Therefore, the health disparities observed in the study can be understood through this lens, as those with higher average SES among other Latino groups may benefit from better health outcomes due to their resources and support systems.

The other options do not provide a strong foundation for understanding the health differences observed. The level of social support, assimilation, or stress levels, while relevant to health, does not directly address the significant impact of socioeconomic factors on health outcomes.
