Hispanics were particularly vulnerable to exposure and susceptibility to H1N1 (2). However, Hispanics had the lowest rates of H1N1-related ICU admission and significantly lower risk of having H1N1-related ICU visits. Logistic regression models indicate that these differences are not explained by the large differences in SES. This is contrary to other reports and could be related to the low mean age of this group. Future work should address how lower age among Hispanics influences H1N1-related ICU stay Á especially in young Hispanic women.
