简介
Objectives
To estimate global, regional (21 regions) and national (187 countries) sodium intakes in adults in 1990 and 2010.
Design
Bayesian hierarchical modelling using all identifiable primary sources.
Data sources and eligibility
We searched and obtained published and unpublished data from 142 surveys of 24 h urinary sodium and 103 of dietary sodium conducted between 1980 and 2010 across 66 countries. Dietary estimates were converted to urine equivalents based on 79 pairs of dual measurements.
Modelling methods
Bayesian hierarchical modelling used survey data and their characteristics to estimate mean sodium intake, by sex, 5 years age group and associated uncertainty for persons aged 20+ in 187 countries in 1990 and 2010. Country-level covariates were national income/person and composition of food supplies.
Main outcome measures
Mean sodium intake (g/day) as estimable by 24 h …
