Objective To investigate the association between coffee consumption and hypertension risk. Methods Using data from the 2005–2020 National Health and Nutrition Examination Survey (NHANES) on 41,685 adults, multivariable logistic regression models examined the relationship between categorical coffee intake (none, 0 to 1, ≥1 to 2, ≥2 to 3, ≥3 to 4, and ≥4 cups/day) and hypertension, with stratified and curve-fitting analyses. Results Compared to non-consumers, moderate daily intake of 1–3 cups was significantly associated with lower hypertension odds (OR 0.829–0.869, p 0.05), more prominently in those 60 years (OR 0.957, 95% CI 0.940–0.975). Curve fitting revealed a U-shaped association between coffee consumption and hypertension risk. Conclusion While a moderate coffee intake (1–3 cups/day) was associated with a lower prevalence of hypertension, especially among adults under 60 years, this cross-sectional study cannot establish causality. Further prospective studies are needed to confirm these findings.
