IntroductionPhysical activity is recognised as a central component of overall approaches to primary prevention in reducing morbidity and mortality and improving well-being. 1 However, current societal trends have led to decreases in energy expenditure. 2 Encouraging the sedentary person to be more active is a public health priority and the health promotion agenda for the 21st century includes promoting incidental physical activity as part of an overall plan for active living. 3 Therefore, the current emphasis in physical activity promotion is on the accumulation of lifestyle activity. [4][5][6] Consistent with the current recommendations for physical activity, people should be encouraged to accumulate physical activity throughout the day.7 Even small amounts of activity may lead to the accumulation of an adequate level of energy expenditure over the course of the day. 8 An option easily accessible and feasible to most people for accumulating incidental physical activity is the use of stairs instead of an escalator or lift, particularly in an occupational setting where there are likely to be multiple trips during the day.Stair climbing is a physiologically vigorous physical activity shown to require 8.6 times more energy expenditure than the resting state.
9Regular stair climbing also has well-documented health dividends such as increased fitness and strength, weight loss, improved lipid profiles and reduced risk of osteoporosis. 10 In addition, stair climbing is free and readily available to most people. Most studies that have attempted to increase the use of stairs compared with an orIgInal research arTIcle are point-of-decision prompts in a sports science and medicine centre effective in changing the prevalence of stair usage? a preliminary study abstract objective. To determine the impact of a signed intervention on promoting stair versus lift usage in a health and fitness facility.
Design.A 3-week observational study in which a simple timeseries design of collecting data before, during and after the introduction of an intervention was used.setting. The Sports Science Institute of South Africa (SSISA): a 5-storey building with a centrally located lift lobby and internal stairwell.Method. Observers were placed unobtrusively on the ground floor, with good visibility of lift/stairwell, to observe ascending movement of students, staff, tenants, visitors and patients 4 hours/day (07h00 -09h00, 16h00 -18h00), 4 days/week for 3 weeks. During week 2, motivational signs were displayed on the wall next to the lift and stairs and on the floor leading to the stairwell. In week 3, signage was removed. Factors considered in predicting stair use were gender, phase of intervention, and whether persons were staff/students or visitors. to 53% during the intervention to 50% after the intervention. Odds of using the stairs during the intervention increased by 45% (odds ratio (OR) 1.45, 95% confidence interval (CI) 1.25 -1.68) (p<0.00001), were 41% higher for staff/students compared with visitors (p<0.00001) and were 55% greater ...
