“…11 Part of the cost difference may be explained by the LIFE-P physical activity intervention having more group exercise sessions than the DPP intervention, and less time spent on individualized instruction and behavioral counseling. An interesting study by Sevick et al 13 compared 2 different types of exercise interventions and found that a behaviorally-based lifestyle intervention cost much less than an exercise intervention consisting of supervised in-center exercise and paid health club memberships. These interventions cost $279 (behaviorally-based) and $1140 (supervised) respectively in just the first 6 months of the program, but are hard to compare with the LIFE-P intervention.…”

We examined the costs of a physical activity (PA) and an educational comparison intervention. 424 older adults at risk for mobility disability were randomly assigned to either condition. The PA program consisted of center-based exercise sessions 3× weekly for 8 weeks, 2× weekly for weeks 9 to 24 and weekly behavioral counseling for 10 weeks. Optional sessions were offered during maintenance weeks . The comparison intervention consisted of weekly education meetings for 24 weeks, and then monthly for 6 months. Cost analyses were conducted from the "payer's" perspective, with a 1-year time horizon. Intervention costs were estimated by tracking personnel activities and materials used for each intervention and multiplying by national unit cost averages. The average cost/participant was $1134 and $175 for the PA and the comparison interventions, respectively. A preliminary cost/effectiveness analysis gauged the cost/disability avoided to be $28,206. Costs for this PA program for older adults are comparable to those of other PA interventions. The results are preliminary and a longer study is required to fully assess the costs and health benefits of these interventions. NIH-PA Author ManuscriptNIH-PA Author Manuscript NIH-PA Author ManuscriptImpaired mobility, defined as being able to "walk safely and independently," 1 is common among older adults and has been found to predict broader disability involving activities of daily living and independence. 2,3 A subgroup of the older adult population at risk for future disability 4-7 is characterized by a sedentary lifestyle and impaired mobility. More specifically, high risk older adults walk more slowly and have reduced strength and balance but can still perform most daily living activities.In an attempt to address the needs of this high risk population and prevent them from becoming more fully disabled, an intensive physical activity intervention has been developed and evaluated in the Lifestyle Interventions and Independence for Elders Pilot Study (LIFE-P), a randomized controlled trial of physical activity compared with a "successful aging" educational intervention. After 12 months, participants randomly assigned to the physical activity (PA) intervention were less likely to reach the endpoint of major mobility disability in comparison with participants in the successful aging (SA) comparison group. 8 Major mobility disability was defined as the inability to complete a 400-m walk. 9 In addition, participants in the PA group had significantly higher mean scores on the Short Physical Performance Battery (SPPB) and faster mean walking times in the 400-m walk.Physical activity interventions can vary widely in their methodology, intensity, and the amount of resources required to conduct them. [10][11][12][13][14] In this paper, we examine the resources required to achieve the health benefits associated with the physical activity intervention in the (LIFE-P) study. MethodsData for this study were collected in 2004 to 2006 and analyses were conducted in 2007 to 2008. De...

Evidence-based intervention in physical activity: lessons from around the world

Promotion of physical activity is a priority for health agencies. We searched for reviews of physical activity interventions, published between 2000 and 2011, and identified effective, promising, or emerging interventions from around the world. The informational approaches of community-wide and mass media campaigns, and short physical activity messages targeting key community sites are recommended. Behavioural and social approaches are effective, introducing social support for physical activity within communities and worksites, and school-based strategies that encompass physical education, classroom activities, after-school sports, and active transport. Recommended environmental and policy approaches include creation and improvement of access to places for physical activity with informational outreach activities, community-scale and street-scale urban design and land use, active transport policy and practices, and community-wide policies and planning. Thus, many approaches lead to acceptable increases in physical activity among people of various ages, and from different social groups, countries, and communities.

“…Studies [12-14] have indicated that interventions delivered using a face-to-face approach (ie, structured PA programs and individual counseling) have been effective for PA behavior changes, but effects have been small. Due to time schedules, high running costs, and geographic restrictions, these interventions could not reach and be accessed by a large population [15-18]. With the combination of small effects and limited reach, the impact of face-to-face PA interventions on public health has been modest [19].…”

BackgroundA growing body of research has employed information and communication technologies (ICTs) such as the Internet and mobile phones for disseminating physical activity (PA) interventions with young populations. Although several systematic reviews have documented the effects of ICT-based interventions on PA behavior, very few have focused on children and adolescents specifically.ObjectivesThe present review aimed to systematically evaluate the efficacy and methodological quality of ICT-based PA interventions for children and adolescents based on evidence from randomized controlled trials.MethodsElectronic databases Medline, PsycInfo, CINAHL, and Web of Science were searched to retrieve English language articles published in international academic peer-reviewed journals from January 1, 1997, through December 31, 2009. Included were articles that provided descriptions of interventions designed to improve PA-related cognitive, psychosocial, and behavioral outcomes and that used randomized controlled trial design, included only children (6-12 years old) and adolescents (13-18 years old) in both intervention and control groups, and employed Internet, email, and/or short message services (SMS, also known as text messaging) as one or more major or assistive modes to deliver the intervention.ResultsIn total, 9 studies were analyzed in the present review. All studies were published after 2000 and conducted in Western countries. Of the 9 studies, 7 demonstrated positive and significant within-group differences in at least one psychosocial or behavioral PA outcome. In all, 3 studies reported positive and significant between-group differences favoring the ICT group. When between-group differences were compared across studies, effect sizes were small in 6 studies and large in 3 studies. With respect to methodological quality, 7 of the 9 studies had good methodological quality. Failure to report allocation concealment, blinding to outcome assessment, and lack of long-term follow-up were the criteria met by the fewest studies. In addition, 5 studies measured the intervention exposure rate and only 1 study employed objective measures to record data.ConclusionThe present review provides evidence supporting the positive effects of ICTs in PA interventions for children and adolescents, especially when used with other delivery approaches (ie, face-to-face). Because ICT delivery approaches are often mixed with other approaches and these studies sometimes lack a comparable control group, additional research is needed to establish the true independent effects of ICT as an intervention delivery mode. Although two-thirds of the studies demonstrated satisfactory methodological quality, several quality criteria should be considered in future studies: clear descriptions of allocation concealment and blinding of outcome assessment, extension of intervention duration, and employment of objective measures in intervention exposure rate. Due to the small number of studies that met inclusion criteria and the lack of consistent evidence, res...
