Abstract:
Objective To evaluate whether Point of Decision Prompt (PDP) could effectively increase the use of stairs in the Chinese university dormitory buildings.Methods Number and certain features of students who used stairs and lifts were respectively recorded through observation in both buildings A (intervened) and building B (not intervened) simultaneously one week before the intervention (stage Ⅰ),the first week after the intervention (stage Ⅱ) and the fourth week after the intervention (stage Ⅲ).Self-questionnaires were also used to evaluate the effect of the intervention program in building A.Results According to the observation,the overall stair-use in building A increased from 34.3% in stage Ⅰ to 37.5% (P<0.05,compared with stage Ⅰ) in stage Ⅱ and dropped to 35.4% (P<0.05,compared with stage Ⅰ) in stage Ⅲ.In contrast,the change in the overall stair-use in building B between these three stages was not statistically significant.The change of the stair-use varied with different sexes,different directions (up or down) and different days (weekday or weekend).Data from the questionnaires showed that 97.3% of the students being surveyed reported that they had noticed the PDPs and 26.4% of whom reported that they had increased the frequency of stair-use.Results from the logistic analysis of the questionnaire showed that girls (OR=8.78,95% CI:3.23-23.87,deff= 1.24) and those who lived under the fifth floor (OR=2.78,95%CI:1.28-6.06,deff= 1.38) were more inclined to increase the stair-use.Conclusion PDP could effectively increase the frequency of stair-use in the Chinese university dormitory buildings.
