East Tennessee: Publishes on Smoking and Homocysteine Levels

Mr. Ogbebor Omoike, student in East Tennessee State University College of Public Health’s doctoral program, recently published research in Biomarkers.  The article, “Association between smoking status and homocysteine levels and possible effect modification by cholesterol and estradiol” discusses the amino acid homocysteine and its possible relationship with whether or not a person smokes.

Co-authors include Dr. Hadii Mamudu and Ms. Manul Awasthi of the ETSU College of Public Health Department of Health Services Management and Policy.  Additional co-authors include Dr. Timir Paul of the Quillen College of Medicine, Dr. Stanley Ridner of the ETSU College of Nursing, and Dr. Sam Harirforoosh of the Bill Gatton College of Pharmacy.

Environmental and dietary exposures alter the levels of homocysteine in the human body; however, little is known about the association of smoking status with homocysteine levels. This study aimed to examine the association of smoking status with homocysteine levels and to determine whether the association is modified by estradiol, a female hormone, or cholesterol, a type of lipid.

Data were obtained from National Health and Nutrition Examination Survey 2003-2004 with analysis done in 2018 on 4,580 adults aged 20 years and older. A current smoker defined as a person who smoked at least 100 cigarettes in his/her lifetime and at least once in the last month; a former smoker is one who had smoked less than 100 cigarettes and had quit smoking at the time of the interview; a “never smoker” is an adult who never smoked cigarettes in their lifetime or less than 100 cigarettes in his/her lifetime.
