Background The Healthy 4U-2 study sought to evaluate the effect of a twelve-week, physical activity (PA) coaching intervention for changes and maintenance in PA, anthropometrics and health-related outcomes in adults presenting to an ambulatory hospital clinic.
Methods One hundred and twenty insufficiently active adults were recruited from an ambulatory hospital clinic and randomised to an intervention group that received an education session and five 20-minute telephone sessions of PA coaching, or to a control group that received the education session only. ActiGraph GT3X accelerometers were used to measure moderate-to-vigorous physical activity (MVPA) at baseline, post-intervention (3-months) and follow-up (9-months). Secondary outcome measures (anthropometrics, PA self-efficacy, health-related and quality of life) were also assessed at the three time points.
Results At baseline, the mean age and body mass index of participants were 53 ± 8 years and 31 ± 4 kg/m 2 , respectively. Relative to control, the intervention group increased objectively measured MVPA at post-intervention (p<0.001) and 9 months follow-up (p<0.001). At the 9-month follow-up the intervention group completed 22 min/day of MVPA (95% CI: 20 to 25 min/day), which is sufficient to meet the recommended PA guidelines. The intervention group exhibited beneficial changes in body mass (p<0.001), waist circumference (p<0.001), body mass index (p<0.001), PA self-efficacy (p<0.001), and health-related quality of life (p<0.001) at the 9-month follow-up.
Conclusions This study demonstrates that a low contact PA coaching intervention results in beneficial changes in PA, anthropometrics and health-related outcomes in insufficiently active adults presenting to an ambulatory care clinic. The significant beneficial changes were measured at post-intervention and the 9-month follow-up, demonstrating a maintenance effect of the intervention.
