Members of some minority ethnic groups experience worse health than other groups. Here is a example of some research:                                                                                                                                                           Richer minority ethnic groups, including Indians and African Asians including Pakistani, Bangladeshi and Caribbean communities.

How do we explain these inequalities in health?                                                                                                     One explanation for these inequalities in health is that they reflect social class differences.

The most recent migrants – such as those Bangladeshi and Pakistani and Indian descent to be concentrated in the lowest occupational groups and in the poorest housing, as well as;

 low-paid manual occupations;
jobs in industries that are most hazardous to health, such as laundry, textiles and clothing industries;
occupations that have been especially affected by successive economics recessions, such as in textiles and footwear.
Shift work, poor job security and fringe benefits, low pay and the high risk of unemployed are all likely to lead to poorer health among black and minority ethnic communities.
So the differences in health not linked to specific genetic, diseases are likely to be linked to poverty.
