Key result
US birth and longer US residence are linked to higher allostatic load in Hispanics under 55.
Why the study?
Allostatic load has been little studied in US Hispanics/Latinos, and patterns by age, sex, and nativity remain unclear.
Does nativity status and duration of US residence affect allostatic load in Hispanic/Latino populations?
Population
15,830 Hispanic/Latinos aged 18–74 years, 77% foreign-born
Comparison
US-born vs foreign-born with varying duration of US residence and age at immigration
Design
Observational study within the Hispanic Community Health Study/Study of Latinos

Highlights potential acculturation-related risks in young Hispanics/Latinos; extends healthy immigrant hypothesis but remains hypothesis-generating.

Does nativity status and duration of US residence affect allostatic load in Hispanic/Latino populations?
p-value: p=<0.0001
The study supports a 'healthy immigrant' pattern where US-born Hispanics/Latinos and those with longer US residence have higher allostatic load compared to recent immigrants.
Salazar et al. (2016) conducted an observational in Allostatic load (n=15,830). Nativity status and duration of US residence vs. US-born individuals and foreign-born with shorter duration of US residence was evaluated on Allostatic load (AL) score (p=<0.0001). In Hispanics/Latinos <55 years old, allostatic load was highest among US-born individuals and increased among the foreign-born with longer US residence (P<0.0001 for increasing trend).
