Serum homocysteine level in vegetarians in District Tharparker, Sindh

Abstract

Objectives: The aim of present study was to investigate serum homocysteine levels in apparently healthy vegetarians and ominvores in Mithi, district Tharparker, Sindh, Pakistan. Methods: This study was conducted in the Department of Biochemistry, Basic Medical Sciences Institute (BMSI), Jinnah Postgraduate Medical Center (JPMC), Karachi and blood samples were collected from Mithi, district Tharparker, Sindh, Pakistan, in 2012. One hundred vegetarian and one hundred omnivores (age ranging from 20-40 years) were enrolled for this study. Serum homocysteine levels were measured by the chemiluminescence enzyme immunoassay method. Results: Serum homocysteine (Hcy) level was considerably higher (p<0.001) in vegetarian group compared to omnivores. We further grouped and analyzed our study subjects according to their gender and according to Hcy level (greater than or lower than 15μmol/L). A considerable number of vegetarian subjects 30% were having Hcy >15μmol/L compared to omnivores 6%, (p<0.001). Gender-wise comparison showed that 27.02% male and 38.46% females had >15μmol/L serum Hcy level in vegetarian group and 6.9% male and 3.5% females had >15μmol/L serum Hcy level in omnivores group, but the difference was not significant in any group. Conclusion: Vegetarians are more prone to develop hyperhomocysteinemia, so they are at high risk to develop cardiovascular disease.
