Abstract

Elevated circulating homocysteine (Hcy) is considered as an independent cardiovascular disease risk factor. Hyperhomocysteinaemia (HHcy) is influenced by nutritional, genetic, and environmental factors. The purpose of the study was to assess HHcy prevalence in Benin, its association with intakes of B-vitamins (B2, B6, B9, B12), alcohol intake, and socio-economic status (SES), and its links with other factors of cardio-metabolic risk. The cross-sectional study included 541 apparently healthy subjects, aged 25 to 65 years, from three sites: the main city, a small city and a rural area. Hcy was measured with an ELISA test kit. The HHcy cut-off was 12 μmol/L. Dietary intake was assessed with three 24-hour recalls. We used a structured questionnaire to assess alcohol consumption, demographics, and SES according to education and an amenity score as income proxy. Criteria for obesity, hypertension, dyslipidemia and hyperglycemia were primarily those of World Health Organization (WHO) and the International Diabetes Federation. Mean age was 38.1 ± 10.1 years. The prevalence of HHcy was 52.2% in men and 24.7% in women. In multiple linear regression models, Hcy in men was positively associated with alcohol intake, but only alcohol in beer...Continue Reading

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.
