OBJECTIVE: The objective of this study was to compare the costs associated with Internet and print-based physical activity interventions. METHOD: The costs associated with delivering tailored print and Internet-based interventions were estimated from a randomized controlled physical activity trial (n=167). The estimates were based on research assistant time sampling surveys, web development invoices, and other tracking procedures. RESULTS: Web-development costs for the Internet intervention were $109,564. Taken together with the website hosting fees and staff costs, the cost per participant per month was $122.52 The cost of the print intervention was $35.81 per participant per month. However, in a break-even analysis, the Internet intervention became more cost-efficient, relative to the print intervention, when the total number of participants exceeded 352. CONCLUSIONS: Relative to print-based interventions, Internet-based interventions may be a more cost efficient way to reach a large number of sedentary individuals.

    ABSTRACT: Computer-tailored physical activity interventions are becoming increasingly popular. Recent reviews have comprehensively synthesised published research on computer-tailored interventions delivered via interactive technology (e.g. web-based programs) but there is a paucity of synthesis for interventions delivered via traditional print-based media in the physical activity domain (i.e. tailored-print interventions). The current study provides a systematic review of the tailored-print literature, to identify key factors relating to efficacy in tailored-print physical activity interventions. Computer-tailored print intervention studies published up until May 2010 were identified through a search of three databases: Medline, CINAHL, and Psycinfo; and by searching reference lists of relevant publications, hand searching journals and by reviewing publications lists of 11 key authors who have published in this field. The search identified 12 interventions with evaluations reported in 26 publications. Seven out of the 12 identified studies reported positive intervention effects on physical activity behaviour, ranging from one month to 24 months post-baseline and 3 months to 18 months post-intervention. The majority of studies reporting positive intervention effects were theory-based interventions with multiple intervention contacts. There is preliminary evidence that tailored-print interventions are a promising approach to promoting physical activity in adult populations. Future research is needed to further identify key factors relating to efficacy and to determine if this approach is cost-effective and sustainable in the long-term.

    ABSTRACT: Physical inactivity is an important risk factor in several highly prevalent diseases, being associated with worse quality of life and higher mortality. Despite the implementation of a several global, national and local policy instruments and strategies to promote physical activity (PA), including Internet platforms and advertising campaign, approximately two thirds of the European adult population reports low adherence to an active lifestyle, impairing health benefits that exercise can provide. Increasing efforts to provide adequate information have been made, and the use of new technologies tools has increased, but little investigation focus on the effect of information exposure on knowledge retention, regarding effects of physical inactivity in health. The objective of the present study is to evaluate differences among people in the use of new information technologies as information source on PA, regarding their perceptions of benefits of an active lifestyle and characteristics of adequate physical activity to health improvement. The study included a randomly recruited sample of 879 subjects (53% males; 47% females), age 42.3±19.4 years old. A survey was designed to (1) identify main information sources; (2) relate perceived knowledge and PA information sources; (3) relate knowledge retention on adequate PA for health benefits and PA information sources; (4) relate perceived necessity of more information regarding PA and information sources and (5) relate PA levels and information sources. Results show that two information sources (teacher and sport professionals) positively influence perception of proper PA information. Results also found teachers, Internet and sport professionals as PA information sources that most influence their users, regarding Knowledge retention. We also found that rely on friends/family; teachers, Internet and sport professionals as PA information sources positively influence the adoption of an active lifestyle.

    ABSTRACT: This article provides a comprehensive review of Internet- and Website-based physical activity interventions targeting adult populations. Search procedures identified 72 unique Internet-based physical activity interventions published in peer-reviewed journals. Participants of the studies were predominately White, middle-aged (mean age = 43.3 years), and female (65.9%). Intervention durations ranged from 2 weeks to 13 months (median = 12 weeks). Forty-six of the studies were randomized controlled trials, 21 were randomized trials without a control condition, 2 were non-randomized controlled trials, and 3 used a single-group design. The majority of studies (n = 68) assessed outcomes immediately following the end of the intervention period, and 16 studies provided delayed postintervention assessments. Forty-four of the 72 studies (61.1%) reported significant increases in physical activity. Future directions for Internet-based physical activity interventions include increasing representation of minority and male populations in Internet-based efforts, conducting delayed postintervention follow-up assessments, and incorporating emerging technologies (ie, cellular and Smartphones) into Internet-based physical activity efforts.
