Low IQ = higher heart risk
LONDON - INTELLIGENCE comes second only to smoking as a predictor of heart disease, scientists said on Wednesday, suggesting public health campaigns may need to be designed for people with lower IQs if they are to work.
Research by Britain's Medical Research Council (MRC) found that lower intelligence quotient (IQ) scores were associated with higher rates of heart disease and death, and were more important indicators than any other risk factors except smoking.
Heart disease is the leading killer of men and women Europe, the United States and most industrialised countries. According to the World Health Organisation, cardiovascular diseases and diabetes accounted for 32 per cent of all deaths around the world in 2005.
It is well known that people with poorer education and lower incomes often face higher risks of ill health and a range of diseases. Studies have pointed to many likely reasons, including limited access to healthcare and other resources, poorer living conditions, chronic stress and higher rates of lifestyle risk factors like smoking.
The MRC study, which analysed data from 1,145 men and women aged around 55 and followed up for 20 years, rated the top five heart disease risk factors as cigarette smoking, IQ, low income, high blood pressure, and low physical activity.
The researchers, led by David Batty of the MRC and Social and Public Health Science Unit in Glasgow, Scotland, said there were 'a number of plausible mechanisms' which might explain why lower IQ scores could raise the risk of heart disease - in particular a person's approach to 'healthy behaviour'. -- REUTERS
