BACKGROUND: India is undergoing rapid epidemiological and nutritional transition largely as a consequence of rapid urbanisation. We investigated conventional and novel cardiovascular risk factors in rural and urban Indian men and studied their association with markers of vascular damage. METHODS: We randomly selected and studied 149 rural, 142 urban slum residents and 150 urban middle class middle aged Indian men. We measured conventional (obesity, blood pressure, lipids, smoking habits) and novel (proinflammatory and prothrombotic factors) cardiovascular risk factors and markers of vascular damage (carotid intima media thickness (IMT), von Willebrand Factor (vWF), e-selectin). RESULTS: There was a progressive increase in most of the conventional cardiovascular (CV) risk factors from rural to slum to urban middle class men. Plasminogen activator inhibitor-1 (PAI-1), platelet count, total homocysteine and C-reactive protein showed similar patterns. Carotid IMT was similar in the three groups; vWF was highest in rural and e-selectin in slum men. Adjusting for location, age explained 17%, obesity 3% and conventional risk factors 1% of the variance in carotid IMT, whilst novel cardiovascular risk factors were without any significant impact. CONCLUSIONS: Urbanisation increases obesity related as well as prothrombotic and proinflammatoryCV risk factors in Indian men, but appears not to impact on IMT.
