Abstract 14473: The Impact of Dietary Patterns on Cardiovascular Death Comparing Populations of United States and Great Britain: An Analysis of the Global Burden of Disease Study 2019

Abstract

Introduction: Dietary risk factors contribute to cardiovascular mortality. To the best of our knowledge, there are no studies comparing two first world countries with respect to cardiovascular deaths (CVD) and the impact of dietary risk factors. We sought to compare these parameters in Great Britain (GBR) and the United States of America (USA) Methods: A total of 33,041,416 patients with dietary risk factors and CVD from GBR and USA was obtained from the Global Burden of Disease Study between 1990 and 2016.The 30-year mean CVD was compared for all risk factors with the Welch Two sample t-test. Trends of CVD proportions of 30-years is as shown (Fig 1 and 2). Results: 30-year mean cardiovascular death for all variables between GBR and USA was statistically significant (p< 0.05) with the exception of diet low in whole grains. Cardiovascular death with risk factors of diet low in PUFA, fruits, vegetable, nuts and seeds were measures where GBR had a higher 30-year mean CVD than the USA. Remaining factors contributed to higher CVD proportion in USA. Conclusions: A higher proportion of CVD was seen in the USA with dietary risk factors including low PUFA, processed meat, sweetened beverages, low legumes, high sodium and high trans-fatty acids when compared to GBR. Our study proves that there exists significant disparity in CVD proportions between two first world countries despite similar dietary risk factors.
