title: Piloting the feasibility and effectiveness of print- and telephone-mediated interventions for promoting the adoption of physical activity in Australian adults.
abstract: This study examined the feasibility and effectiveness for increasing physical activity of a print-based intervention, and a print- plus telephone-mediated intervention among mid-life and older Australian adults. A randomised controlled trial study design was used. In mid-2002, 66 adults (18 men, 48 women) aged 45-78 years, who identified themselves as underactive, were recruited through advertisements and word-of-mouth at two sites (Melbourne and Brisbane), and randomised to either the print or print-plus-telephone mediated intervention group. Participants in both groups attended an initial briefing session, and over the 12-week intervention period received an instructional newsletter and use of a pedometer (both groups), and individualised telephone calls (print-plus-telephone group only). Self-reported physical activity data were collected at baseline, 12 and 16 weeks. Measures of self-reported global physical activity, moderate-vigorous intensity activity and walking all showed increases between baseline and 12 weeks for both intervention groups. These increases were generally maintained by 16 weeks, although participants in the print-plus-telephone group maintained slightly higher levels of global reported activity and walking (by approximately 30 mins/wk) than those in the print group. These interventions show potential for promoting initial increases in physical activity among mid-life and older Australian adults, and should be evaluated across more extended time periods.
