Global dietary quality in 185 countries from 1990 to 2018 show wide ... nature.com Nature Sep 19, 2022 15 facts

claimResearchers quantified global, regional, and national dietary patterns among children and adults across 185 countries between 1990 and 2018 using data from the Global Dietary Database project.

procedureThe Global Dietary Database (GDD) researchers used a Bayesian model to estimate the log-means of dietary intake within a nested hierarchical structure to account for differences in survey methods, representativeness, time trends, input data, and uncertainty.

procedureThe Global Dietary Database (GDD) researchers evaluated dietary intakes adjusted to age-standardized energy intakes to assess dietary composition independently of quantity, account for estimated age-specific average requirements, and reduce measurement error.

referenceModelled estimates of individual food and nutrient intakes by population subgroup, country, region, and globe for 1990 and 2018 are available for download from the Global Dietary Database (GDD) website.

procedureThe Global Dietary Database (GDD) researchers quantified uncertainty of stratum-specific dietary factor estimates using 4,000 iterations to determine posterior distributions jointly by country, year, age, sex, education, and urbanicity.

procedureThe Global Dietary Database (GDD) researchers obtained and assessed survey characteristics including survey name, country, years performed, sampling methods, response rate, national representativeness, level of data collection, dietary assessment method, sample size, population demographics, and definitions of dietary factors.

measurementThe Global Dietary Database (GDD) model included estimates of consumption for 264 subgroups across 185 countries, covering 99.0% of the world’s population in 2018.

procedureThe researchers validated the Global Dietary Database (GDD) results using five-fold cross-validation, which involved randomly omitting 20% of the raw survey data and running the process five times, comparing predicted versus observed intakes, assessing implausible estimates, and visually assessing national mean intakes using global heat maps.

claimNational estimates of dietary habits from the FAO and the Global Dietary Database show differences when compared.

referenceV. Miller et al. reported on global, regional, and national consumption of animal-source foods between 1990 and 2018 using findings from the Global Dietary Database, published in The Lancet Planetary Health in 2022.

claimR. Micha harmonized the individual dietary surveys included in the Global Dietary Database (GDD) for the study.

claimThe Global Dietary Database (GDD) researchers extracted individual-level dietary intakes of up to 53 foods, beverages, and nutrients, stratified by age, sex, education, and urban/rural residence.

claimThe Bayesian model used by the Global Dietary Database (GDD) included random effects by country and region, sex, education, urban/rural residence, non-linear age effects, survey-level indicator data for dietary assessment methods, and national year-specific covariate data.

referenceThe Global Dietary Database (GDD) is a collaborative effort that systematically identifies, compiles, and standardizes individual-level dietary data on 53 foods, beverages, and nutrients.

procedureThe Global Dietary Database (GDD) uses Bayesian modelling methods to estimate dietary intakes jointly stratified by age, sex, education level, and urbanicity for 185 countries between 1990 and 2018.

referenceThe 2021 Global Nutrition Report's Figure 2.3, which details deaths attributable to dietary risk factors, is based on food intake estimates from the Global Dietary Database, weight measurements from the NCD Risk Factor Collaboration, diet-disease relationships from epidemiological literature, and mortality and population estimates from the Global Burden of Disease project.

referenceThe analysis of premature death attributable to dietary risks was based on estimates of food intake from the Global Dietary Database, weight measurements from the NCD Risk Factor Collaboration, diet-disease relationships from the epidemiological literature, and mortality and population estimates from the Global Burden of Disease project.
