Dyslipidaemia is an important modifiable risk factor for development of cardiovascular disease. Dyslipidaemia is a medical disorder described as an increase in any or all lipid profiles and/or lipoproteins in the blood. The major risk factors for dyslipidaemia include changes in lifestyle and dietary habits, such as eating saturated fat more than 10% and fat consumption more than 40% of total calories/day. The aim of this study is to determine the prevalence of dyslipidaemia among adults in Saudi Arabia. Sixty-two male adults aged 35 years and older participated in this study. The researcher collected body mass index and blood samples. The study results indicated that 91.9% of male adults have low high-density lipoprotein cholesterol (< 40 mg/dl). The findings also showed that 24.2% of male adults have high triglycerides (≥ 150 mg/dl). Moreover, 11.3% of male adults have high total cholesterol (≥ 200 mg/dl). The results also indicated that 16% of male adults have high low-density lipoprotein (≥100 mg/dl).
