Cardiovascular disease burden attributable to dietary risk factors from 1990 to 2019: A systematic analysis of the Global Burden of Disease study

Dietary risks have always been a major risk factor for cardiovascular diseases (CVDs), especially in young people. This article aimed to provide an updated and comprehensive view of the spatial, temporal and sexual heterogeneity in diet-attributable CVD burdens from 1990 to 2019. Data on diet-attributable CVD burdens were extracted from the Global Burden of Disease (GBD) Study 2019. Numbers and age-standardized rates (ASRs) of deaths, disability-adjusted life years (DALYs) and corresponding estimated annual percentage change (EAPC) were determined. Globally, the number of diet-attributable CVD deaths and DALYs in 2019 were 6.9 million and 153.2 million, marking 43.8% and 34.3% increases since 1990, respectively. However, ASRs of death and DALYs have declined over time. The regions with the highest ASRs of diet-related CVD deaths and DALYs were in Central Asia, whereas the lowest ASRs of CVD deaths and DALYs were observed in the high-income Asia Pacific region. Globally, men suffered higher death and DALY burdens than women. Ischemic heart disease and stroke were the leading causes of CVD deaths and DALYs, globally. Regarding the specific diet group, diets low in whole grains, high in sodium, low in fruits, low in nuts and seeds, low in vegetables and low in seafood omega-3 fatty acids contributed to CVD deaths and DALYs the most. Dietary risks accounted for a higher proportion in people aged less than 65 years old. Diet-attributable CVDs threaten public health, particularly in low SDI countries and younger generations. As diet-related CVDs are nation-specific, the prioritization of public health interventions should be evidence-based. •Data was extracted from the most updated GBD database—GBD 2019.•We summarized the three decades of diet-attributable CVD burdens by the age, gender, locations and socio-demographic index.•Ischemic heart disease and stroke were the leading causes of CVDs death and DALYs globally.•Diets high in sodium, low in whole grains and fruits were the main dietary risks for CVD.•Dietary risks accounted for a higher proportion in people under 65 years old.
