Does a salt reduction intervention program using an electronic salt sensor and cellular phone reduce blood pressure in hypertensive male workers?
A workplace intervention using an electronic salt sensor and personalized mobile feedback effectively reduces blood pressure and salt intake in hypertensive workers.
May support short-term workplace salt reduction for BP control in hypertensive men; hypothesis-generating, needs larger RCTs before adoption.
We investigated the effectiveness of a workplace intervention program that utilized self-monitoring of daily salt excretion by an electronic salt sensor and sent personalized e-mail advice via cellular phone. Forty-one hypertensive male workers were assigned to intervention and control groups, then counseled together. Intervention group members were asked to measure daily salt excretion and received e-mail advice. After 4 weeks, a greater decrease of blood pressure (BP) was observed in the intervention group, with significant reductions to daily salt excretion and home BP. The new intervention program is considered useful for BP control among hypertensive workers.

Morikawa et al. (2011) conducted an RCT in Hypertension (n=41). Salt reduction intervention program using an electronic salt sensor and cellular phone vs. Control group was evaluated on Blood pressure and daily salt excretion. A workplace salt reduction intervention using an electronic salt sensor and cellular phone significantly reduced daily salt excretion and home blood pressure among hypertensive male workers at 4 weeks.
