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 .
Body and soul. A dietary intervention conducted through African-American churches.
OBJECTIVES Body and Soul was a collaborative effort among two research universities , a national voluntary agency ( American Cancer Society ) , and the National Institutes of Health to disseminate and evaluate under real-world conditions the impact of previously developed dietary interventions for African Americans . METHODS Body and Soul was constructed from two successful research -based interventions conducted in African-American churches . Components deemed essential from the prior interventions were combined , and then tested in a cluster r and omized-effectiveness trial . The primary outcome was fruit and vegetable intake measured with two types of food frequency question naires  at baseline and 6-month follow-up . RESULTS At the 6-month follow-up , intervention participants showed significantly greater fruit and vegetable ( F&V ) intake relative to controls . Post-test differences were 0.7 and 1.4 servings for the 2-item and 17-item F&V frequency measures , respectively . Statistically significant positive changes in fat intake , motivation to eat F&V , social support , and efficacy to eat F&V were also observed . CONCLUSIONS The results suggest that research -based interventions , delivered collaboratively by community volunteers and a health-related voluntary agency , can be effectively implemented under real-world conditions
