ABSTRACT
Health promotion increasingly employs participatory approaches, but the question arises whether the likely higher costs of participation also translate into greater benefits. This article takes a first step toward a full health economic evaluation by comprehensively reporting the costs of a specific participatory approach, Cooperative Planning, in a German research consortium to promote physical activity. We conducted a costing analysis of Cooperative Planning at 22 sites across six settings. Project teams used a custom template to record resource use. We calculated average costs per meeting, site and setting using the opportunity costs approach, and obtained feedback from participating researchers. A total of 144 planning meetings with an average of nine participants were conducted. Costs per meeting varied significantly across settings. Differences were mostly attributable to varying meeting duration, preparation time and numbers of participants. Across settings, human resources accounted for roughly 95% of the costs. Implementing researchers reported challenges regarding the logic and methods of the health economic analysis. A participatory approach to physical activity promotion may cause substantially varying costs in different settings despite similar cost structures. However, their value for money could turn out comparably favorable if (and only if) the expected benefits is indeed forthcoming. Despite some challenges implementing the costing exercise into the logistics of ongoing participatory projects, this analysis may pave the way toward a full health economic evaluation, and the template may be useful to future participatory health promotion projects.

BACKGROUND: Despite growing recognition of the need to promote physical activity, the existing evidence base on the cost-effectiveness of relevant interventions appears scant and scattered. This systematic review of reviews set out to take stock of the evidence on the cost-effectiveness of physical activity interventions. METHODS: Ten literature databases were systematically searched for available reviews on the cost-effectiveness of physical activity interventions, complemented by a hand search. Out of the 515 articles identified, 18 reviews met the inclusion criteria. A quality appraisal of the 18 reviews was undertaken. RESULTS: Of the 18 reviews, 4 contained information on the target group of children and adolescents, 12 on adults, 3 on older adults, and 6 on the general population. Across the reviews some intervention strategies were identified as being particularly cost-effective, including certain school-based interventions (children and adolescents), interventions using pedometers (adults), fall prevention programs (older people), mass media campaigns and environmental approaches (general population). However, for some of these approaches (e.g. mass media campaigns), the underlying evidence of being able to change physical activity behavior remains inconsistent. CONCLUSION: Available evidence for the cost-effectiveness of physical activity interventions is scattered, but points towards the cost-effectiveness of certain interventions. Until this moment, cost-effectiveness has more often been studied for individual-level interventions. This is potentially due to some methodological challenges in assessing the cost-effectiveness of population-based interventions.
ABSTRACT
On the basis of international published reviews, this systematic review aims to determine the health economic benefits of interventions promoting physical activity.This review of reviews is based on a systematic literature research in 10 databases (e. g. PubMed, Scopus, SPORTDiscus) supplemented by hand searches from January 2000 to October 2015. Publications were considered in the English or German language only. Results of identified reviews were derived.In total, 18 reviews were identified that could be attributed to interventions promoting physical activity (2 reviews focusing on population-based physical activity interventions, 10 reviews on individual-based and 6 reviews on both population-based and individual-based physical activity interventions). Results showed that population-based physical activity interventions are of great health economic potential if reaching a wider population at comparably low costs. Outstanding are political and environmental strategies, as well as interventions supporting behavioural change through information. The most comprehensive documentation for interventions promoting physical activity could be found for individual-based strategies (i. e. exercise advice or exercise programs). However, such programs are comparatively less cost-effective due to limited reach and higher utilization of resources.The present study provides an extensive review and analysis of the current international state of research regarding the health economic evaluation of interventions promoting physical activity. Results show favourable cost-effectiveness for interventions promoting physical activity, though significant differences in the effectiveness between various interventions were noticed. The greatest potential for cost-effectiveness can be seen in population-based interventions. At the same time, there is a need to acknowledge the limitations of the economic evidence in this field which are attributable to methodological challenges and research deficits.
