Objective: To assess the net 5 year effects of
intervention of a community based demonstration project, the Heartbeat Wales programme, on modifiable behavioural risks for prevention of
cardiovascular disease.
Design and setting: Quasi-experimental design
comparing results from two independent cross sectional population
surveys conducted in 1985 and 1990 in Wales and a matched reference
area in north east England.
Subjects: Random, stratified samples of people aged
18-64 years (18 538 in 1985 and 13 045 in 1990) in Wales and in north
east England (1483 and 4534, respectively).
Intervention: A coordinated range of activities for
heart health promotion in Wales entailing public education campaigns along with supportive policy and infrastructure change. In the reference area no additional community heart health promotion was
planned, though considerable activity did take place,
"contaminating" the reference area.
Main outcome measures: Fifteen self reported
behavioural indicators relating to dietary choice, smoking, frequency of exercise, and weight.
Results: Positive changes (for health) in behavioural
outcomes were observed among the population in Wales, including a
reduction in reported smoking prevalence and improvements in dietary
choice. There was no net intervention effect for the programme over and
above observed change in the reference area.
Conclusions: No definite conclusions can be drawn
concerning the efficacy of the programme in terms of behavioural outcomes. With hindsight, the difficulties of evaluating such a complex
multifaceted intervention were underestimated. Further debate on the
most appropriate methods for assessing the effectiveness of community
based health promotion programmes is called for.
