Introduction: Smoking is a major risk factor of cardiovascular disease. Evidence suggests that smoking may reduce insulin sensitivity, induce insulin resistance, and exacerbate other cardiovascular risk factors such as elevated plasma triglycerides, reduced high density lipoproteinâ€“cholesterol, and hyperglycemia. Several studies have also shown that smoking may increase the risk of metabolic syndrome.
Materials and Methods: In the present community-based, cross-sectional study, 99 individuals were divided into two groups, cigarette smokers (50 members) and non-smokers( 49 members).The survey included questions about age, education level, occupation, income, marital status, smoking habits, alcohol and khat consumption, exercise, previous and current diseases, and family disease history, among all individuals. Blood pressure, plasma lipid profiles and CRP were measured.
Results: There were no statistically significant differences in body mass index (p= 0.667), systolic blood pressure (p=0.107) and diastolic blood pressure (p= 0.256) between smokers and non-smokers. There were, however, statistically significant elevations in total cholesterol (p = 0.000), LDL-C (p = 0.002) and triglycerides (p=0.000), HDL-C (p= 0.025) and CRP (p=0.001) in smokers compared with non-smokers.
Conclusion: We found that cigarette smoking is associated with elevated plasma triglycerides, total cholesterol, HDL-C LDL-C and CRP levels. The HDL-C elevation in smokers was related to increased alcohol consumption: smokers who did not use alcohol had HDL-C levels similar to non-smokers. Among smokers, alcohol consumption was also significantly associated with an increase in both systolic and diastolic blood pressure. The sample size of this research was small, so further studies with larger sample size are recommended.
