Persons who engage in such active and effortful coping strategies, while also contending with social and economic hardships may experience adverse health Covariates: Age, Gender, Use of hypertensive medication effects such as HBP4.

The odds of high JH scores were not • The influence of JH on the health of Latinos has not been investigated. While JH was conceptualized as a construct that statistically significant for measures of SEP including education, poverty level, and employment status (p>0.05) reflects the health consequences of race-based oppression 4 experienced by Blacks , an examination of the application of JH to RQ 2: John Henryism is positively associated with high blood the experience of Latinos, the largest and fastest growing pressure (Model 1; p=0.02). 6,7 racialized group in the U.S. , is warranted. Similar to Blacks, Latinos experience social, economic, and political marginalization. RQ 3: Socioeconomic position did not modify the relationship between JH and blood pressure (Model 2 & 3; p>0.05). Further, Latinos are increasingly subjected to anti-immigrant Table 2.
