Can Primary Care Change Elderly Physical Activity and Salt Intake? An Australian Pilot Trial (ECOBEING)

Brief Summary:
A randomised controlled trial to test if offering three visits to a dietician + two visits to a physiotherapist over six months + a home sphygmomanometer, will result in a reduction in sodium intake and an increase in fitness in people over 75yrs. Volunteers were enrolled from Oct 2008 to July 2009.

Condition or disease Intervention/treatment Phase
Health Behaviour Behavioral: Lifestyle counselling Not Applicable

Detailed Description:
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.

Arm Intervention/treatment
Experimental: Lifestyle counselling

Three dietician visits focussed on education to find food with sodium less than 120mg/100gms.

Two physiotherapist visits focussed on teaching personalised sustainable practical exercise.

Behavioral: Lifestyle counselling

  • salt reduction in the elderly
  • increased fitness in the elderly

No Intervention: Control
Control group was offered free skin cancer check and wait listed for the same lifestyle counselling after the six months of the study.

Primary Outcome Measures :
  1. the change in morning urine sodium/potassium ratio [ Time Frame: between enrollment and six months ]
    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.

  2. the increased distance in a six minute walk test [ Time Frame: between enrollment and six months ]
    to measure objectively an increase in fitness the increase in the six minute walk test was used

Secondary Outcome Measures :
  1. change in systolic BP [ Time Frame: between enrollment and six months ]
    teaching people to reduce sodium intake and increase fitness may reduce systolic blood pressure as a secondary outcome

  2. change in doses/day of antihypertensive medication [ Time Frame: between enrollment and six months ]
    teaching reduction in sodium and increased fitness may mean people need less antihypertensive medication as a secondary outcome

  3. change in waist measurement [ Time Frame: between enrollment and six months ]
    teaching increased fitness would be expected to reduce waist measurement as a secondary outcome

  4. change in weight & BMI [ Time Frame: between enrollment and six months ]
    teaching increased fitness would be expected to reduce weight and therefore calculated Body Mass Index as a secondary outcome

  5. change in cognition measurement [ Time Frame: between enrollment and six months ]
    Cognition measurements using the Standardised Mini-Mental State Examination, and the more comprehensive and sensitive Addenbrooke Cognitive Examination to compare those in the intervention group with the highest and lowest quartiles of reduction in sodium intake + increased fitness (equally weighted), as a secondary outcome of teaching these lifestyle changes.
