Key result
Behavior change interventions cut daily urinary sodium excretion by ~486 mg vs. control.
Why the study?
High salt intake increases the risk of hypertension and cardiovascular disease, but the effectiveness of behavioral interventions to reduce sodium intake in adults needed investigation.
Do behavior change interventions reduce sodium intake in adults?

Khalesi et al. (2021) conducted a systematic review in High salt intake (n=75,169). Behavior change interventions vs. Control or usual care was evaluated on Urinary sodium excretion (MD -486.19 mg/d, 95% CI -669.44 to -302.95, p=<0.001). Behavior change interventions significantly reduced urinary sodium excretion by a mean difference of 486.19 mg/d compared to control, equivalent to a reduction of >1 g of salt intake daily.
