Context-Ethnoracial differences may exist in exposure to trauma and post-traumatic outcomes. However, Asian-Americans and Native Hawaiians/Other Pacific Islanders (NHOPI) are vastly underrepresented in research pertaining to trauma and health status sequelae.Objective-To determine whether there are ethnoracial disparities in sexual trauma exposure and its sequelae for health and functioning among Asian-Americans and NHOPI.Design, Setting, Participants-We examined data on sexual assault exposure from the [2006][2007] Hawai`i Behavioral Risk Factor Surveillance System (H-BRFSS), cross-sectional adult community-based probability sample (n = 12,573). Data were collected via computer-assisted random-digit landline telephone survey. Survey response rate was found to be about 48% in 2006 and 52% in 2007. Main Outcome Measures-Demographic information, the Sexual Violence Module regarding unwanted sexual experiences, and questions about health lifestyles, chronic diseases and disability, and health status and quality of life.Results-Participants were 42.3% White, 14.4% NHOPI, and 39.3% Asian-American. NHOPI had a higher 12-month period prevalence (2.24 per 100, CI=1.32-3.78) of any unwanted sexual experience, but a lower prevalence estimate and odds ratio for any lifetime unwanted sexual experience (prevalence: 9.38 per 100, CI=7.59-11.55; odds ratio: 0.61, CI=0.47-0.81) relative to Whites, after adjusting for age, gender, income and education level. Asian-Americans had lower prevalence estimates for 12-month period prevalence (0.78 per 100, CI=0.44-1.39), and lower lifetime prevalence estimates and odds ratios (prevalence: 3.91 per 100, CI=3.23-4.72; odds ratio: 0.27, CI=0.21-0.34). 12-month and lifetime prevalence estimate any unwanted sexual experiences for Whites were 0.71 per 100 (CI=0.45-1.12) and 12.01 per 100 (CI=10.96-13.14), respectively. Sexual assault experiences were highly associated with adverse health status sequelae (e.g., disability, poor general health), but there were no significant ethnoracial disparities on selfreported health outcomes among those with a lifetime history of unwanted sexual experiences. (2) or collapse different minority groups together in a way that may obscure disparities between groups (3). This is of concern because interpersonal violence has dramatic adverse effects on mental and physical health, and is a major risk factor for a range of medical comorbidities (4-7). Lower socioeconomic status is a risk factor for assaultive violence (4); in turn, ethnic minorities are disproportionally of lower socioeconomic status, thus placing some members of ethnic minority groups at higher risk for exposure to violence.Because of wide variation in the percentage of regional representation in the U.S. population, some ethnoracial minorities, such as Asian-Americans and Pacific Islanders, typically appear in insufficient numbers in nationally-representative epidemiological samples to permit meaningful conclusions. Additionally, few studies have been designed to examine trauma in A...
