Final answer:
The 'Immigrant paradox; better', referring to the phenomenon where new immigrants often have better health outcomes than their descendants in the United States.
Step-by-step explanation:
According to the Immigrant paradox, people who immigrate to the United States have better health outcomes than people in later generations do. This observation aligns with research findings indicating that despite facing socioeconomic challenges, immigrant populations often display surprisingly positive health outcomes when they first arrive in the United States. This is attributed to a variety of factors, including cultural practices, dietary habits, and a selection effect wherein healthier individuals are more likely to migrate.
The socioeconomic status health gradient, on the other hand, refers to the well-documented correlation that individuals with higher socioeconomic status generally have better health outcomes. This concept highlights how wealth and health are interconnected, serving as mutual determinants with wealthier individuals often enjoying better health. This gradient exists within the broader population but is not directly related to the generational differences in health outcomes observed in immigrants.
