Survey of 1,170 Participants
The quantitative survey included 1,170 participants across three Chinese provinces, with 1,025 successful 24-hour urine samples.
The study also used qualitative interviews among participants with different urinary-sodium levels.
High Acceptability but Persistent Barriers
Acceptability and adherence to the salt substitute were high.
However, inadequate knowledge, misconceptions about salt reduction and habitual intake of high-sodium pickled foods were identified as major barriers.
Implementation Lesson
Changing household cooking or table salt addresses only one component of total sodium exposure.
Other high-sodium foods and behaviors can persist and limit the expected reduction.
