Social capital, ethnic density and mental health among ethnic minority people in England: a mixed-methods study.

OBJECTIVES: Ethnic minority people have been suggested to be healthier when living in areas with a higher concentration of people from their own ethnic group, a so-called ethnic density effect. Explanations behind the ethnic density effect propose that positive health outcomes are partially attributed to the protective and buffering effects of increased social capital on health. In fact, a parallel literature has reported increased levels of social capital in areas of greater ethnic residential diversity, but to date, no study in England has explored whether increased social capital mediates the relationship between protective effects attributed to the residential concentration of ethnic minority groups and health. DESIGN: We employ a mixed-methods approach to examine the association between ethnicity, social capital and mental health. We analyse geocoded data from the 2004 Health Survey for England to examine the association between (1) ethnic residential concentration and health; (2) ethnic residential concentration and social capital; (3) social capital and health; and (4) the mediating effect of social capital on the association between the residential concentration of ethnic groups and health. To further add to our understanding of the processes involved, data from a qualitative study of quality older ethnic minority people were be used to examine accounts of the significance of place of residence to quality of life. RESULTS: The association between ethnic density and social capital varies depending on the level of measurement of social capital and differed across ethnic minority groups. Social capital was not found to mediate the association between ethnic density and health. Structural differences in the characteristics of the neighbourhoods where different ethnic groups reside are reflected in the accounts of their daily experiences, and we observed different narratives of neighbourhood experiences between Indian and Caribbean respondents. The use of mixed methods provides an important contribution to the study of ethnic minority people's experience of their neighbourhood, as this approach has allowed us to gain important insights that cannot be inferred from quantitative or qualitative data alone.

[Hypertension in Dutch and English ethnic minorities. Blood pressure better controlled in English groups than in Dutch groups]. / Hypertensie in Nederlandse en Engelse etnische minderheidsgroepen. Bloeddruk in Engelse groepen beter onder controle dan in Nederlandse.

OBJECTIVE: To compare blood pressure and the prevalence of hypertension in white Dutch and Dutch of Suriname-hindustani and Suriname-creole ethnic derivation with corresponding ethnic minority groups in England and to assess the quality of hypertension treatment in these groups. DESIGN: Retrospective; comparison of cross-sectional studies. METHOD: Secondary analyses were performed on data from 3 population-based studies with 13,999 participants in total of European, African of South-Asian origin from England and the Netherlands. RESULTS: English South-Asian men and women had lower blood pressure and lower prevalence of hypertension than people of South-Asian origin in the Netherlands (Suriname-hindustani), except for systolic blood pressure in men of Indian extraction in England. There was no difference in systolic blood pressure between groups of African origin in the Netherlands and England. Diastolic blood pressure levels, however, were lower in English men and women of African origin than in people of African origin in the Netherlands (Suriname-creole). White Dutch had higher systolic blood pressure levels, but lower diastolic blood pressure levels than white English men and women. There was no difference in the prevalence of hypertension between the white groups. In persons being treated for hypertension, a substantially lower percentage of the Suriname-hindustani and Suriname-creole persons in the Netherlands had well controlled blood pressure (lower than 140/90 mmHg) than their English equivalents, with the exception of English of Indian extraction. CONCLUSION: There were marked differences in blood pressure and prevalence of hypertension between comparable ethnic groups in England and the Netherlands. The relatively poor blood pressure control in Dutch ethnic minority groups partly explained the relatively high blood pressure levels in these groups.

A cross-national comparative study of blood pressure and hypertension between English and Dutch South-Asian- and African-origin populations: the role of national context.

BACKGROUND: We compare patterns of blood pressure (BP) and prevalence of hypertension between white-Dutch and their South-Asian and African minority groups with their corresponding white-English and their South-Asian and African ethnic minority groups; and the contribution of physical activity, body sizes, and socioeconomic position (SEP); and the quality of BP treatment that may underlie differences in mean BP. METHODS: Secondary analyses of population-based studies of 13,999 participants from the United Kingdom and the Netherlands. RESULTS: Compared with Dutch South-Asians, all English South-Asian men and women had lower BP and prevalence of hypertension except for systolic BP in English-Indian men. Among Africans, the systolic BP did not differ, but the diastolic BP levels were lower in English-Caribbean and English- (sub-Sahara) African men and women than in their Dutch-African counterparts. English-Caribbeans had a lower prevalence of hypertension than Dutch-Africans. Compared with white-Dutch, white-English men and women had higher systolic BP levels, but lower diastolic BP levels. There were no differences in the prevalence of hypertension between the white groups. Most differences remained unchanged after adjustment for SEP, lifestyle, and body sizes in all ethnic groups. BP control rates were substantially lower among Dutch-African and Dutch South-Asian hypertensives than among their English counterparts (except Indians). CONCLUSIONS: We found marked variations in BP and hypertension prevalence between comparable ethnic groups in England and the Netherlands. Poor BP control among Dutch South-Asians and Africans contributed to their disadvantage of the relatively high BP levels.

The Black diaspora and health inequalities in the US and England: does where you go and how you get there make a difference?

The relatively poor health of Black American people in the US and Black Caribbean people in England is a consistent finding in the health inequalities literature. Indeed, there are many similarities between the health, social, economic and demographic profiles of these two groups. However, there is evidence that Caribbean people in the US are faring considerably better. This paper explores differences in the social and economic position of Black American, Black Caribbean and white people in the US and Black Caribbean and white people in England, how these relate to ethnic inequalities in health, and may be underpinned by differences in patterns and contexts of migration. We use similar surveys from the US and England to explore these questions. The US data were drawn from the National Survey of American Life and the English data were drawn from the Health Survey for England and a follow up study. Findings show the advantaged health position of Caribbean American people in comparison with both Caribbean people in England and Black American people. Multivariate analyses indicate that these differences, and the differences in health between Black and white people in the two countries, are a consequence of social and economic inequalities.
