South Asians in UK have higher ischemic heart disease mortality
30th September 2010: British black Africans and black Caribbeans have lower ischemic heart disease mortality rates compared to white Europeans, a new research has found.
The results from the Child Heart and Health Study in England (CHASE) also note South Asians in the UK have higher ischemic heart disease mortality.
The research also notes that the changing diets in immigrants to the UK leads to significant changes to lipid profiles.
For reaching the conclusions, Angela S. Donin from the University of London and colleagues examined blood lipid and dietary macronutrient intake patterns among 2529 British children aged between 9 and 10 years.
Reasoning that ethnic differences in lipid concentrations might play a part in these differences, the children examined were from white European, black African, black Caribbean, and South Asian origin.
Black African children obtained fewer calories from fat and saturated fat, and more calories from carbohydrates. They had markedly lower mean total, LDL-cholesterol, and triglyceride concentrations, than white European children.
Black Caribbean children, on the other hand, consumed calories from fat and carbohydrates similar to those in white European children, and had mean total, LDL- and HDL-cholesterol, and triglyceride concentrations similar to their white European counterparts.
South Asian children consumed more calories overall, including more calories from total fat and polyunsaturated fat and relatively fewer calories from saturated fat and carbohydrates, and their mean total and LDL-cholesterol concentrations were similar to those in white European children. Their mean HDL-cholesterol was markedly lower, and their triglyceride concentrations were higher.
The research found that the differences in total and LDL cholesterol levels between black African and white European children essentially went away after adjustment for saturated fat intake.
The differences in lipid levels between black Caribbean and South Asian children and white European children did not change significantly after adjustment for dietary macronutrients.
The results did not materially alter with adjustment for socioeconomic status, physical activity level, and lunch type.
The investigators concluded their report in the August 25th American Journal of Clinical Nutrition by saying only black African children have a lipid profile that is likely to be protective against future ischemic heart disease risk.
Changes in the dietary patterns of the other ethnic groups can have adverse effects on their blood lipid profiles. Efforts to limit the loss of traditional dietary patterns, or to modify the newly adopted patterns, could help to control ischemic heart disease risk in these population groups in the next generation.
