Accumulating research suggests that racism may be a major determinant of health. Here we report associations between self-reported experience of racial discrimination and health in New Zealand. Data from the 2002/2003 New Zealand Health Survey, a cross-sectional survey involving face-to-face interviews with 12,500 people, were analysed. Five items were included to capture racial discrimination in two dimensions: experience of ethnically motivated attack (physical or verbal), or unfair treatment because of ethnicity (by a health professional, in work or when gaining housing). Ethnicity was classified using self-identification to one of four ethnic groups: Māori, Pacific, Asian and European/Other peoples. Logistic regression, accounting for the survey design, age, sex, ethnicity and deprivation, was used to estimate odds ratios (OR) and 95% confidence intervals (CI). Māori reported the highest prevalence of "ever" experiencing any of the forms of racial discrimination (34%), followed by similar levels among Asian (28%) and Pacific peoples (25%). Māori were almost 10 times more likely to experience multiple types of discrimination compared to European/Others (4.5% vs. 0.5%). Reported experience of racial discrimination was associated with each of the measures of health examined. Experience of any one of the five types of discrimination was significantly associated with poor or fair self-rated health; lower physical functioning; lower mental health; smoking; and cardiovascular disease. There was strong evidence of a dose-response relationship between the number of reported types of discrimination and each health measure. These results highlight the need for racism to be considered in efforts to eliminate ethnic inequalities in health.

Background: Inequalities in health between different ethnic groups in New Zealand are most pronounced between Māori and Europeans. Our aim was to assess the effect of self-reported racial discrimination and deprivation on health inequalities in these two ethnic groups., Methods: We used data from the 2002/03 New Zealand Health Survey to assess prevalence of experiences of self-reported racial discrimination in Māori (n=4108) and Europeans (n=6269) by analysing the responses to five questions about: verbal attacks, physical attacks, and unfair treatment by a health professional, at work, or when buying or renting housing. We did logistic regression analyses to assess the effect of adjustment for experience of racial discrimination and deprivation on ethnic inequalities for various health outcomes., Findings: Māori were more likely to report experiences of self-reported racial discrimination in all instances assessed, and were almost ten times more likely to experience discrimination in three or more settings than were Europeans (4.5% [95% CI 3.2-5.8] vs 0.5% [0.3-0.7]). After adjustment for discrimination and deprivation, odds ratios (95% CI) comparing Māori and European ethnic groups were reduced from 1.67 (1.35-2.08) to 1.18 (0.92-1.50) for poor or fair self-rated health, 1.70 (1.42-2.02) to 1.21 (1.00-1.47) for low physical functioning, 1.30 (1.11-1.54) to 1.02 (0.85-1.22) for low mental health, and 1.46 (1.12-1.91) to 1.11 (0.82-1.51) for cardiovascular disease., Interpretation: Racism, both interpersonal and institutional, contributes to Māori health losses and leads to inequalities in health between Māori and Europeans in New Zealand. Interventions and policies to improve Māori health and address these inequalities should take into account the health effects of racism.

Background: The aim of this study was to explore the relationship between risk of psychosis, common mental disorder (CMD) and indicators of racism among ethnic minority groups in England and how this relationship may vary by particular ethnic groups., Method: A multivariate analysis was carried out of quantitative, cross-sectional data from a nationally representative community sample of people aged between 16 and 74 years from the largest ethnic minority groups in England: those of Caribbean, Indian, Pakistani, Bangladeshi and Irish origin., Results: Experience of interpersonal racism and perceiving racism in the wider society each have independent effects on the risk of CMD and psychosis, after controlling for the effects of gender, age and socio-economic status. There was some variation in the findings when they were conducted for separate ethnic and gender groups., Conclusions: An understanding of the relationship between racism and mental health may go some way towards explaining the ethnic variations found in both CMD and, particularly, psychosis.

Objectives: We measured perceived discrimination and its association with common mental disorders among workers in the United Kingdom., Methods: We conducted a secondary analysis of a national sample of 6 ethnic groups (n=2054). Discrimination was measured as reports of insults; unfair treatment at work; or job denial stemming from race, religion, or language. The outcome assessed was presence of common mental disorders., Results: The risk of mental disorders was highest among ethnic minority individuals reporting unfair treatment (odds ratio [OR]=2.0; 95% confidence interval [CI]=1.2, 3.2) and racial insults (OR=2.3; 95% CI=1.4, 3.6). The overall greatest risks were observed among Black Caribbeans exposed to unfair treatment at work (OR=2.9; 95% CI=1.2, 7.3) and Indian (OR=3.1; 95% CI=1.4, 7.2), Bangladeshi (OR=32.9; 95% CI=2.5, 436.0), and Irish (OR=2.9; 95% CI=1.1, 7.6) individuals reporting insults., Conclusions: Racial/ethnic discrimination shows strong associations with common mental disorders.

Objectives: This study explored associations between racism, social class, and health among ethnic minority people in England and Wales., Methods: We conducted a series of regression analyses on cross-sectional data from the Fourth National Survey of Ethnic Minorities to explore the relation between different indicators of racism and health and household occupational class., Results: Marked independent associations existed between reported experience of racism and perceptions of Britain as a "racist society," household social class, age, sex, and various mental and physical health indicators. These associations showed reasonable consistency across the different ethnic groups., Conclusions: The different ways in which racism may manifest itself (as interpersonal violence, institutional discrimination, or socioeconomic disadvantage) all have independent detrimental effects on health, regardless of the health indicator used.
