Increasing physical activity (PA) is an international public health priority. This study aims to assess the impact of an environmental stair‐use intervention using “point of decision” prompts with varying messages in an NHS workplace in the UK.
Observational data were collected using a covert method (infra‐red sensors) in an interrupted time‐series design over an eight‐week period. Intervention consisted of posters displaying encouraging messages in the entrance to two stairways of an acute NHS hospital. The hospital site is a public building accessible to patients, staff (n=∼7,000), students and the general public. Questionnaires (n=221) assessed employee self‐reports of and attitudes towards stair‐use.
Following 24‐hour observational counts (n=143,514) no statistically significant differences were seen in either stair climbing or descent on either stairway through the introduction and removal of promotional posters. A number of determinants and barriers to stair‐use were identified. Posters were reported as “seen” by a low proportion of respondents (7‐25 per cent) and only a small number felt encouraged to use the stairs as a result of the prompts (25‐37 per cent of those who “saw” them, 3‐18 per cent of total sample).
The study evaluates the impact of a stair‐use intervention in a public hospital building, a setting within which research investigations have to date been limited. More research is needed to further investigate determinants and barriers to stair‐use and the impact of different message types and locations of “point‐of‐decision” prompts in a hospital setting.
Environmental interventions to increase stair‐use in this setting may be best placed within a comprehensive workplace programme including health education and multi‐component interventions.
“Point of decision” prompts are inexpensive as a long‐term intervention. As part of a large‐scale workplace health campaign, encouraging even a small percentage of employees to use the stairs in organisations of this size is of significance to workplace health promoters.
