InputSourceDescription
Dietary intakesGlobal Dietary Database23
  • Age-specific and sex-specific energy-adjusted dietary intakes of 11 dietary factors in 188 countries.*

  • Data from national and subnational population-based surveys.

Metabolic mediatorsNon-Communicable Disease Risk Factor Collaboration64 65
  • Age-specific and sex-specific mean of BMI and SBP and prevalence of hypertension in 191 countries in 2010.†

  • Data from national and subnational population-based surveys.

Relative risks for dietary and metabolic mediator impact on diseasePublished meta-analyses24 25
  • Age-specific relationships between dietary factors and diseases, dietary factors and metabolic mediators, and mediators and diseases from prospective cohorts and randomised clinical trials.‡

  • Thirty-six diet–disease pairs are available.

DALYsGlobal Health Data Exchange27
  • Age-specific and sex-specific DALYs for 12 cardiometabolic diseases in 195 countries in 2010.§

  • DALYs comprise both years of life lost and years lived with disability.

PopulationGlobal Health Data Exchange66
  • Number of people for each age-specific, sex-specific and country-specific category in 196 countries in 2010.¶

  • *Data were available from 20 to 80+ years old by 5-year age intervals. Age groups in other data sources were adjusted to match the age groups in the dietary intake data.

  • †Data were available from 25 to 85+ years old by 5-year age intervals. In accordance with the dietary intake data, groups of 80–84 years and over 85 years were collapsed to the group of over 80 years by population weighting.

  • ‡Data were available from 25 to 75+ years old by 5-year age intervals. In accordance with the dietary intake data, the age groups of 75–79 years and over 80 years were created using the data from group of 75+ years old.

  • §Data were available from 1 to 80+ years old by 5-year age intervals originally. Only age groups above 25 years old were used in this analysis.

  • ¶Population estimates for men and women were available from 0 to 104 years old by 5-year age intervals for 196 countries. Total population for both sexes were calculated by summing up the sex-specific data in each country-age group.

  • BMI, body mass index; DALYs, disability-adjusted life years; SBP, systolic blood pressure.
