Study type
Description of intervention(s) / exposure
Group1. Face to face feedback (once only 45 minute session ) of absolute cardiovascular risk to patient with advice on risk factor profile and lifestyle changes to improve risk, together with individualised written materials.
Group 2. Face to face feedback (once only 45 minute session) plus telephone support and counselling (monthly phone calls for 6 months and then bi-monthly phone calls for 6 months - 9 phone calls of 10-12 minutes duration)`
Group 3. Control group - usual general practice care

Comparator / control treatment
The control group will receive their usual general practice care. General Practitioners (GP) will receive their pathology results for ethical reasons.

Primary outcome [4] 240510 0
Urinary Sodium Excretion will be measured in a single, timed, overnight, non-fasting urine collection- not by 24 hour urine collection. Aliquots of each sample will be measured in duplicate for sodium and potassium using indirect ion selective electrodes and for creatinine by the Abbott Jaffe reaction, all in an Abbott Architect analyser. Urinary sodium will then be converted to daily excretion rates using the multipliers of 8 hour urinary excretion.

Secondary outcome [1] 242413 0
Assess waist-hip ratio using Figure Finder Tape Measure. Measurements are to taken twice, directly over the skin and at the level of the tape. Waist measurement is taken at the level of mid-point between the inferior margin of the last rib and the iliac crest in the mid axillary plane. Hip measurement is taken at the level of the greatest posterior protuberance of the buttocks which usually corresponds anteriorly with the level of the symphysis pubis.

2. Blood pressure will be measured using an OMRON office digital blood pressure HEM-907 monitor after participants have been seated for 3 minutes. Three measurements will be taken two minutes apart and an average of the last two measurements calculated.

total cholesterol to high density lipo-protein (HDL) cholesterol ratio
Blood samples will be taken after a 12 hour fast using the Abbott Architect c8000 analyser. The 3K33 Ultra HDL reagent kit will be used to analyse HDL cholesterol and the Cholesterol Kit List No. 7D62 for cholesterol.

Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
GPs and their practices are recruited by invitational letter.
Once recruited, potential participants are identified using a data search of the GPs client database.
A list of patients is generated and given to the GP for review regarding eligibility and contraindications to participation.
Invitational letter sent to potential participant from the practice, including project description and reply slip.
On reply the participant is issued with an ID number, participant information is sent out, an appointment is made to sign consent forms and perform the baseline assessment.
If the partcipant is assessed as having a ACR of > 10% they are allocated into either the two intervention groups or the control group by cluster randomisation by general practice, based on computer generated random numbers and performed by a person not directly involved in implementation to ensure allocation concealment.

Brief summary
Much cardiovascular disease could be prevented if GPs could encourage their patients to improve their diet, physical activity and smoking behaviour. Communication of risk to patients may change their behaviour but the effectiveness of individualised cardiovascular risk feedback in general practice is not yet known. This study aims determine whether feedback of their cardiovascular risk to patients in general practice can improve lifestyle behaviours associated with cardiovascular disease.
