Prevalence of hyperhomocysteinemia in healthy Indian doctors

Currently, hyperhomocysteinemia is a well-known risk factor for variety of vascular diseases. Prevalence of hyperhomocysteinemia increases with age. Hence, the present study was aimed to investigate the prevalence of hyperhomocysteinemia in healthy upper socio-economic class population in India. Total homocysteine (tHcy) concentration was determined in 1243 (906 men & 337 women) healthy Indian doctors with different age group. Using Third National Health and Nutrition Examination Survey (NHANES III) study criteria, the prevalence of hyperhomocysteinemia was 92.85% among men (>11.4 µmol/L) and 81.60% among women (>10.4 µmol/L). The prevalence of hyperhomocysteinemia was higher among men with mean tHcy concentration (21.96 ± 0.38 µmol/L) significantly higher (P<0.0001) than women (15.90 ± 0.39 µmol/L) (95% CI, 4.733- 7.376). Our study showed very high prevalence of hyperhomocysteinemia which may point to the future risk for various pathologies in the present subset of population. Further studies to look at the plasma levels of homocysteine lowering vitamins are warranted to prevent the future risk of vascular diseases.
