Coffee consumption and abdominal aortic calcification among adults with and without hypertension, diabetes, and cardiovascular diseases

This study was performed to investigate the effect of coffee consumption on abdominal aortic calcification (AAC) among adults with and without hypertension, diabetes, and cardiovascular diseases (CVD). A total of 2548 participants from the National Health and Nutrition Examination Survey (NHANES) 2013–2014 were included. Coffee consumption was obtained from 24-h dietary recalls. Dual-energy X-ray absorptiometry (DXA) was used to measure the severity of AAC. In the fully adjusted model, compared with non-drinkers, high coffee consumption (≥390 g/d) was associated with higher AAC scores among participants with hypertension (β = 0.72, 95% CI: 0.21–1.22), diabetes (β = 1.20, 95% CI: 0.35–2.05), and CVD (β = 2.03, 95% CI: 0.71–3.36). We did not observe such an association among participants without hypertension, diabetes, and CVD. Furthermore, decaffeinated coffee was not associated with AAC. In conclusion, patients with hypertension, diabetes, and CVD should focus on coffee consumption, especially caffeinated coffee, to reduce the burden of AAC. •Heavy caffeinated coffee intake was associated with higher AAC scores in patients with hypertension, diabetes, and CVD.•In participants without hypertension, diabetes, and CVD, coffee consumption has no significant effect on AAC.•Regardless of hypertension, diabetes, and CVD status, no effect of decaffeinated coffee intake on AAC scores was observed.
