Chen W, Eisenberg R, Mowrey WB, et al. - Whether higher consumption of dietary zinc is related to lower abdominal aortic calcification (AAC) in adults in the USA was investigated by performing cross-sectional analyses of 2,535 individuals from the National Health and Nutrition Examination Survey 2013–14. Also, the links of AAC with supplemental zinc consumption, total zinc intake and serum zinc level were explored. Three groups of AAC scores were defined: no AAC (AAC = 0, reference group), mild–moderate (AAC  > 0–≤6) and severe AAC (AAC  > 6). Following adjustments for demographics, comorbidities and laboratory measurements, per 1 mg/day higher consumption of dietary zinc, the odds of having severe AAC were 8% lower vs those without AAC. Supplemental zinc intake, total zinc consumption and serum zinc level were not related to AAC. Overall, findings demonstrated an independent association of higher intake of dietary zinc with lower odds of having severe AAC in noninstitutionalized US adults.
