Why the study?
High sodium intake elevates blood pressure and increases cardiovascular diseases, and sodium intake is high in northern China, including Shandong province.
What proportion of cardiovascular disease deaths are attributable to high sodium intake in adults in Shandong Province, China?
Population
Adults aged 25 to 69 years across 20 counties/districts in Shandong, China
Comparison
Higher sodium intake vs reference intake of 2000 mg/day (5.0 g/day salt) and sodium reduction targets
Design
Population-attributable fraction modeling study using cross-sectional survey and death registration data

Links higher sodium to substantial CVD mortality burden in Shandong; leaves open effects of population reduction on outcomes.
What proportion of cardiovascular disease deaths are attributable to high sodium intake in adults in Shandong Province, China?
Nearly 20% of cardiovascular deaths among adults aged 25 to 69 in Shandong, China, are attributable to high sodium intake, highlighting the substantial potential impact of population-level sodium reduction.
