Effective Change of Behaviour of the Elderly in Normal General Practice
There is evidence that both sedentary lifestyle and high sodium diets contribute to
cardiovascular disease and possibly dementia among the elderly. There is a need to show that
minimal intervention can reduce sodium intake and increase fitness in the elderly. Finland
has shown that five dietician visits/year could change diet in respect to fat and fibre. In
Australia the National Health Insurer (Medicare) funds five allied health visits/year for
those with chronic disease, hence our use of this model. This is consistent with WHO
guidelines for a national approach using existing health infrastructure. The elderly
(75-95yrs) were chosen as this group is thought most difficult to change behaviour and has a
higher incidence of dementia.

the change in morning urine sodium/potassium ratio
this measure is to reflect sodium intake. A 24hr urinary sodium cannot be readily validated as an accurate collection and even in the Trials of Hypertension Prevention study was changed to 8hrs to assist compliance. A spot morning ratio is a useful marker of sodium intake for group evaluation.
