Background:  Intracerebral hemorrhage (ICH) is a hemorrhagic stroke with high morbidity and mortality. Recent studies have shown that minorities such as Native Hawaiians and other Pacific Islanders (NHOPI) with ICH are significantly younger compared to whites. However, the interaction of race and gender, and its impact on observed disparities among a multi-ethnic population in Hawai‘i, have not been studied.

Methods:  Consecutive ICH patients (whites, Asians or NHOPI), who were hospitalized at a single tertiary center on O‘ahu between 2006 and 2013 were retrospectively studied. Clinical characteristics were compared between men and women among the entire cohort, and within the major racial groups.

Results:  A total of 791 patients (NHOPI 19%, Asians 65%, whites 16%) were studied. Overall, men were younger than women (62±16 years vs 67±18 years respectively, P < .0001). Among whites, ages of men and women were similar (men: 67±14 years vs women: 67±17 years, P = .86). However, among Asians, men were significantly younger than women (men: 63±16 years vs women: 70±17 years, P < .0001). Among NHOPI, ages of men and women were similar (men: 53±15 years vs women: 56±17 years, P = .34), although NHOPI group overall had significantly younger age compared to whites and Asians (NHOPI: 54±16 years vs whites: 67±15 years, P < .0001; vs Asians: 66±17, P < .0001).

Conclusions:  Overall, men have younger age of ICH presentation than women. However, this observed gender difference was most significant among Asians, but not among whites or NHOPI.
