Brief summary

A pilot randomized controlled trial will be conducted to investigate the feasibility and effectiveness of a salt intake reduction intervention to young hypertension patients in Hong Kong who had high salt intake.

Detailed description

Convenience sample will be recruited from the community in Hong Kong through different channels of promotion.

Interventions

BEHAVIORALFour-week weekly intervention to reduce salt intake

The intervention group will receive a four-week weekly intervention, about 15 minutes each. Two sessions will be face-to-face and two sessions will be on the phone. The participants will be informed of their 24-hour urinary sodium excretion at each measurement time once available.

OTHERUsual government pamphlets

The control group will receive usual government pamphlets when they know their 24-hour urinary sodium excretion at baseline. However, they will not be informed of their follow-up urinary sodium excretion results immediately.
