Cardiovascular diseases (CVDs) are the leading cause of global mortality and a major contributor to morbidity.  The aim of the study was to investigate the prevalence of alcohol consumption and its association with selected biological risk factors related to cardiovascular disease.  A total number of 622 young adults (306 males and 316 females) aged 21 to 30 years participated in the study. Anthropometric and biochemical measurements were recorded. Alcohol consumption questionnaires were administered. A linear regression model was utilised for the analysis of data.  The prevalence of alcohol consumption was found to be 33.3% (38.6% in males and 28.0% in females).  A strong positive association between alcohol consumption and raised triglycerides (β ranged from 4.088 to 2.393, p<0.001), was observed. The results further showed a significant negative association between alcohol consumption and high-density lipoprotein cholesterol (β ranged from -0.087 to -0.071, p<0.030). Participants who consumed alcohol were more likely to be linked with an increased low-density lipoprotein cholesterol (OR ranged from 1.50 to 1.62, p<0.002). Our findings suggested that alcohol consumption was associated with increased selected biological risk factors for cardiovascular diseases. Health policies should be set to prevent the burden of alcohol related CVD nationally and worldwide.
