This study evaluated the ability of three different messages to encourage stair climbing on the
Barcelona underground. Two weeks of baseline were followed by three banner intervention periods
with three different messages, each for a 2 week period. Follow-up data was gathered two weeks after
removing the messages. Stair climbing increased overall [odds ratio (OR) = 1.45; 95% confidence
intervals (CIs) = 1.25–1.68], with no statistical differences between the messages. During follow-up,
stair climbing remained elevated (OR = 1.22; 95% CIs = 1.01–1.48). These preliminary data suggest stair
climbing interventions, effective in the UK, may prove successful in Catalonia and Spain. Baseline
differences, however, outline the magnitude of the task.^^^^
