We found little evidence of effectiveness of HRLAs for promotion of exercise/improved diets .
Conclusions Overall , there is limited evidence suggesting that HRLAs are cost-effective in terms of changing health-related knowledge , behaviours or health outcomes .
The evidence that does exist indicates that HRLAs are only cost-effective when they target behaviours likely to have a large impact on overall health-related quality of life .
Background Development of new peer or lay health-related lifestyle advisor ( HRLA ) roles is one response to the need to enhance public engagement in , and improve cost-effectiveness of , health improvement interventions .
This article synthesis es evidence on the cost-effectiveness of HRLA interventions aim ed at adults in developed countries , derived from the first systematic review of the effectiveness , cost-effectiveness , equity and acceptability of different types of HRLA role .
Analysis of the Cost-Effectiveness of Mammography Promotion by Volunteers in Rural Communities
The Community Trial of Breast Cancer Screening Promotion assessed the effectiveness and cost-effectiveness of mammography promotion  by community volunteer groups in rural areas using three different intervention approaches : individual counseling , community activities , and a combined intervention including both .  Societal costs of the interventions were calculated and used in conjunction with measures of effectiveness to calculate cost-effectiveness in terms of cost per additional mammogram and cost per year of life saved . Methods of collecting and using cost information to assess the cost-effectiveness of community interventions are described . The Community Activities intervention was found to be the most cost-effective , at approximately $ 2,000 for each additional regular mammography user in the community . The cost per year of life saved associated with mammography promotion was approximately $ 56,000 per year of life saved . Exploratory analyses suggest that the most cost-effective method of promoting mammography use may vary with the target population
