Summary

High salt diet increases risk of development of hypertension. In hypertensive patients, low salt diet decreases blood pressure. Not surprisingly public health authorities endorse low salt diet in hypertensive patients. But, surprisingly, average salt intake among adults in Canada remains stubbornly high. Low effectiveness of "fast counselling" by physicians and nurses on dietary salt is partly the culprit. Methods used in successful clinical trials (eg. provision of meals, community cooking sessions, many hours of counselling by dieticians) cannot be used in routine clinical practice. Hence the investigators propose a study on a pragmatic dietary counselling method suitable for clinical practice.

Hypertensive patients will be randomized to receive standard care (which includes counselling by the usual healthcare team, including doctors and nurses) or to receive additional counselling from a registered dietician. This counselling will include two components: a one hour counselling session, and 4, once-weekly telephone calls.

Effectiveness of this counselling will be measured by checking sodium in the urine from a 24 hour collection (which is a measure of dietary salt intake) at baseline and at 4 weeks. In addition, the investigators will also measure urinary sodium at 1 year, to assess if this effect of counselling persists over a longer time.

Conditions

Interventions

BEHAVIORAL

Dietary Counseling

a standard endorsement of low salt diet and other non-pharmacological interventions such as moderation of alcohol intake, optimal body weight, daily exercise by hypertension nurse and physician AND an additional one on one (family members allowed) one hour long counseling by certified dietician who will assess the patient's dietary habits, endorse and describe the Dietary Approach to Stop Hypertension (DASH) diet, and will establish four weekly half an hour follow ups by telephone to address compliance and any question raised by patient and family members.
