Abstract

Background: Previous studies on the effect of coffee on human health and serum lipids showed mixed conclusions about whether coffee consumption is beneficial or harmful. We evaluated the impact of coffee with different types and preparation methods on the serum lipid profile. The present study aimed to assess the relationship between coffee consumption and coffee types on each component of the lipid profile.
Methodology: In this observational, case-control study, we included 75 patients with dyslipidemia and 75 patients who did not have dyslipidemia, using their lipid profile in the medical records. Dyslipidemia was= defined using the lipid profile levels from the Adult Treatment Panel III Guidelines. None of the patients was on an antihyperlipidemic medication. A questionnaire given to all participants was compiled to determine their coffee consumption. The primary outcome was the association between coffee consumption and dyslipidemia.
Results: Of the population studied, individuals who reported drinking coffee showed a 76% higher risk of dyslipidemia than their counterparts. However, this was not statistically significant (OR = 1.76; 95% CI = 0.74-4.19, p = 0.196). Concerning the lipid profile content, cholesterol level was highest among participants who drank a combination of Arabic/Turkish and black coffee (5.48 ± 1.14) and lowest among those who drank Arabic coffee alone (4.51 ± 1.03, p = 0.001).
Conclusion: We found that individuals who reported drinking coffee showed a higher risk of dyslipidemia than their counterparts. However, this was not statistically significant.
