Efficacy of tailored-print interventions to promote physical activity: a systematic review of randomised trials Camille E Short1*, Erica L James2, Ronald C Plotnikoff3 and Afaf Girgis4
Abstract Objective: 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. Method: 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. Results: 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. Conclusion: 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.
Background Participation in physical activity (PA) is well recognised as an important and modifiable determinant of both psychosocial and physiological health. To date, research on PA emphasises the health benefits associated with participating in regular moderate-vigorous aerobic activity and strength training over one’s lifetime [1-3]. There is also recent evidence to indicate that prolonged sedentary behaviour, such as sitting, may be an independent determinant of health, with prolonged sitting associated with ill health regardless of total leisure time activity [4-6]. Despite the known benefits of maintaining an active lifestyle, many people living in industrialised societies * Correspondence: [email protected] 1 School of Medicine and Public Health, Priority Research Centre for Health Behaviour, Priority Research Centre for Physical Activity and Nutrition, University of Newcastle, Callaghan, Australia Full list of author information is available at the end of the article
are considered to be insufficiently active to induce health benefits [7,8]. In 2000, physical inactivity was estimated to account for 1.9 million deaths wor
