Abstract
- Purpose: Increasing potassium intake, especially in populations with low potassium intake and high sodium intake, has emerged as an important population-level intervention to reduce cardiovascular events. Current guideline recommendations, such as those made by the World Health Organisation, recommend a potassium intake of  > 3.5 g/day. We sought to determine summary estimates for mean potassium intake and sodium/potassium (Na/K) ratio in different regions of the world.<br />Methods: We performed a systematic review and meta-analysis. We identified 104 studies, that included 98 nationally representative surveys and 6 multi-national studies. To account for missingness and incomparability of data, a Bayesian hierarchical imputation model was applied to estimating summary estimates of mean dietary potassium intake (primary outcome) and sodium/potassium ratio.<br />Results: Overall, 104 studies from 52 countries were included (n = 1,640,664). Mean global potassium intake was 2.25 g/day (57 mmol/day) (95% credible interval (CI) 2.05-2.44 g/day), with highest intakes in Eastern and Western Europe (mean intake 3.53g/day, 95% CI 3.05-4.01 g/day and 3.29 g/day, 95% CI 3.13-3.47 g/day, respectively) and lowest intakes in East Asia (mean intake 1.89 g/day; 95% CI 1.55-2.25 g/day). Approximately 31% (95% CI, 30-41%) of global population included have an estimated potassium intake  > 2.5 g/day, with 14% (95% CI 11-17%) above 3.5 g/day.<br />Conclusion: Global mean potassium intake (2.25 g/day) falls below current guideline recommended intake level of  > 3.5 g/day, with only 14% (95% CI 11-17%) of the global population achieving guideline-target mean intake. There was considerable regional variation, with lowest mean potassium intake reported in Asia, and highest intake in Eastern and Western Europe.<br /> (© 2023. The Author(s).)
