In the second approach, the research team used a type of analysis called Mendelian randomization. The team searched through data from more than one million people to investigate the link between education and cardiovascular disease risk focusing on points in the genome where a single 'letter' difference in the DNA - called a single nucleotide polymorphism (SNP) - has been linked to years in schooling.
The team assessed the link between these genetic markers for years in schooling with genetic markers for BMI, blood pressure and lifetime smoking (the researchers only assessed years in education and did not analyze intelligence in any way). Using these two methods, they found that body mass index, blood pressure and smoking contribute to the effect of education, explaining up to 18 per cent, 27 per cent and 34 per cent respectively. Combined, these factors accounted for 40 per cent of the effect of education on cardiovascular risk. Dr Gill said this total is less than would be expected by simply adding the individual percentages for BMI, blood pressure and smoking. This suggests the effect of the three factors have some overlap.
