The association between racism and the physical health of native U.S. populations has yet to be examined despite their high risk for stress-related disorders and a history of discrimination toward them. We examined the correlation between perceived racism and the two physiological stress indices of cortisol level and blood pressure in 146 adult Native Hawaiians. Attributed and felt racism were assessed with a 10-item shortened version of the Oppression Questionnaire. Height, weight, blood pressure (BP), and salivary cortisol samples (AM and PM) were collected and analyzed along with information on Hawaiian ancestry, BMI, age, sex, marital status, education level, general psychological stress, and ethnic identity. The results indicated that Native Hawaiians reporting more attributed racism had significantly (p < .05) lower average cortisol levels than those reporting less attributed racism, after adjusting for socio-demographic, biological, and psychosocial confounders. Native Hawaiians reporting more felt racism had a significantly higher systolic BP than those reporting less, but this association was not significant after adjusting for the aforementioned confounders. Racism appears to be a chronic stressor that can “get under the skin” of Native Hawaiians by affecting their physical health and risk for stress-related diseases, possibly, through mechanisms of cortisol dysregulation.
Mental disorders overall and specific disorder groups (anxiety, mood and substance) are common among Māori and measures of severity indicate that disorders have considerable health impact. Findings provide a platform for informing public health policy and health sector responses to meeting mental health needs of Māori.
Growing Up in New Zealand, a longitudinal study following nearly 7,000 children, has faced some unique challenges in identifying, enrolling, and retaining a large and diverse antenatal cohort. Identification of a study region with population demographics that enabled enrollment of an appropriately diverse sample was required as was intensive community and participant engagement in order to promote the study. Complementary methods used included direct engagement with prospective participants and the community and indirect engagement via media. Thus far, retention rates above 95% have been achieved by maintaining a multimethod approach that includes valuing participants and building trusting relationships, strong brand recognition, community engagement, maintenance of participant contact and location records, ensuring high-quality interactions between the participants and the study, pretesting measures and methods prior to the main cohort, and using participant feedback to inform the measures and methods used in future waves of data collection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
