Objectives To determine whether a remote behaviour change service (Active Steps), delivered by a UK charity, can increase physical activity over a 12-month period in adults with lung disease. Methods Active Steps (n=166) consisted of 1:1 telephone health coaching for 12 months alongside printed (e.g. activity diary and chart, information and goal setting booklet) and digital behaviour change strategies (e.g. exercise videos, motivational newsletters, pedometer). A concurrent control group was recruited (n=80) for comparison. Self-reported physical activity (Short Active Lives Survey) and self-reported health (EQ-VAS) were collected at baseline, 3, 6, and 12 months. Logistic regression models (adjusted for confounders) were used to analyse the odds of becoming physically active or average changes in physical activity time and EQ-VAS. Results Primary outcome : The number of participants defined as physically active at 12 months was greater with Active Steps (46%) compared to controls (23%) which was statistically significant in an unadjusted (odds ratio (OR) 95% confidence intervals (CI):2.8 1.3-6.1, p=0.011) but not adjusted model (OR: 2.2 0.9-5.4, p=0.097). Secondary outcomes : Compared to controls, Active Steps increased the number of participants physically active at 3 and 6 months, increased the weekly minutes of moderate-vigorous physical activity and improved self-reported health (EQ-VAS) across all timepoints. Discussion Our findings suggest that charity-led remote behaviour change support is effective in the short-to-medium-term in adults with lung disease, but high participant attrition necessitates caution in interpreting sustained effect estimates at 12 months. Further long-term evaluations are needed to address adherence and sustainability of such services.
