A Workplace Intervention to Promote Stair Climbing: Greater Effects in the Overweight

Objective: Stair climbing is a lifestyle physical activity that uses more calories per minute than jogging. This study tested an intervention designed to promote stair climbing in a workplace. Because previous studies provide only equivocal evidence of the effects of increased stair climbing in worksites, a formal comparison of the effects of the intervention on stair ascent and descent was made.

Promoting Stair Use: Single Versus Multiple Stair-Riser Messages

Message banners attached to stair risers produced a significant increase in pedestrian stair use, exceeding effects previously reported for conventional posters. Multiple instances of the same message banner, however, were as effective as banners featuring different messages. Therefore, greater visibility, rather than message variety, appears to account for the superiority of the banner format. Our findings indicate the feasibility of simple stair-use promotion campaigns based around the repetition of a single message.

A multi-component stair climbing promotional campaign targeting calorific expenditure for worksites; a quasi-experimental study testing effects on behaviour, attitude and intention

BackgroundAccumulation of lifestyle physical activity is a current aim of health promotion, with increased stair climbing one public health target. While the workplace provides an opportunity for regular stair climbing, evidence for effectiveness of point-of-choice interventions is equivocal. This paper reports a new approach to worksite interventions, aimed at changing attitudes and, hence, behaviour.MethodsPre-testing of calorific expenditure messages used structured interviews with members of the public (n = 300). Effects of multi-component campaigns on stair climbing were tested with quasi-experimental, interrupted time-series designs. In one worksite, a main campaign poster outlining the amount of calorific expenditure obtainable from stair climbing and a conventional point-of-choice prompt were used (Poster alone site). In a second worksite, additional messages in the stairwell about calorific expenditure reinforced the main campaign (Poster + Stairwell messages site). The outcome variables were automated observations of stair and lift ascent (28,854) and descent (29,352) at baseline and for three weeks after the intervention was installed. Post-intervention questionnaires for employees at the worksites assessed responses to the campaign (n = 253). Analyses employed Analysis of Variance with follow-up Bonferroni t-tests (message pre-testing), logistic regression of stair ascent and descent (campaign testing), and Bonferroni t-tests and multiple regression (follow-up questionnaire).ResultsPre-testing of messages based on calorific expenditure suggested they could motivate stair climbing if believed. The new campaign increased stair climbing, with greater effects at the Poster + Stairwell messages site (OR = 1.52, 95% CI = 1.40-1.66) than Posters alone (OR = 1.24, 95% CI = 1.15-1.34). Follow-up revealed higher agreement with two statements about calorific outcomes of stair climbing in the site where they were installed in the stairwell, suggesting more positive attitudes resulted from the intervention. Future intentions for stair use were predicted by motivation by the campaign and beliefs that stair climbing would help weight control.ConclusionsMulti-component campaigns that target attitudes and intentions may substantially increase stair climbing at work.

Increases in Arousal Are Associated with Reductions in the Human Nociceptive Flexion Reflex Threshold and Pain Ratings

The nociceptive flexion reflex has been regarded as an objective correlate of pain perception. This study examined whether the nociceptive flexion reflex is modulated by physiological arousal in the same manner as pain. Cardiovascular activity, nociceptive flexion reflex thresholds, and pain ratings were measured in 40 healthy adults under three conditions that demanded varying degrees of physiological arousal: Rest, number repetition, and mental arithmetic. Heart rates were faster and R-wave to pulse intervals shorter during mental arithmetic than number repetition, whereas heart rates were slower and R-wave to pulse intervals longer during rest compared to number repetition. Both mental arithmetic and number repetition were associated with reduced nociceptive flexion reflex thresholds compared to rest. Although the nociceptive flexion reflex thresholds were the same during mental arithmetic and number repetition, pain ratings were lower during mental arithmetic than number repetition and rest. The resul...

Promoting physical activity in a low socioeconomic area: results from an intervention targeting stair climbing.

OBJECTIVE To compare rates of stair climbing in a high and low socioeconomic (SE) area, and to assess the efficacy of a stair climbing intervention in each area. METHODS From March to May 2009 ascending stair/escalator choices (N=20,315) were observed in two underground train stations located in a high, and low, SE area of Glasgow. Baseline observations preceded a 4-week intervention in which posters, promoting stair choice, were installed. Follow-up observations were collected 1 week after poster removal. RESULTS Baseline stair climbing rates were 12.2% and 7.1% at the high and low SE stations, respectively. Overall, pedestrians at the high SE station were around twice as likely to climb the stairs as those at the low SE station (odds ratio [OR] = 1.91, 95% confidence interval [CI] = 1.70-2.15). Across sites, the rate of stair climbing was higher during the intervention relative to baseline (OR = 1.48, CI = 1.34-1.63) and remained elevated at follow-up (OR = 1.24, CI = 1.11-1.39). Absolute increase in stair climbing was similar at both stations (high SE, +4.7%; low SE, +4.5%), indicating equivalent poster effects in each area. CONCLUSION Pedestrians in lower SE areas appear less likely to climb stairs than pedestrians in high SE areas. Nevertheless, a stair climbing intervention was equally effective in both areas.

Early withdrawal from higher education: A focus on academic experiences

ABSTRACT Early withdrawal from higher education (HE) programmes can be detrimental for the students and institutions involved. Quantitative research has often concentrated on demographic and social antecedents (e.g. gender, prior education). Other factors may be more open to intervention e.g. students’ academic experiences in HE. Using data from an institutional survey (N = 1170), logistic regression tested a range of academic experiences, regarding their relationship to contemplation of withdrawal (‘COW’: a recognised marker for actual withdrawal). COW was associated with student perceptions of low one-to-one contact with staff; non-traditional delivery methods; low peer-interaction; and high assessment load. Interestingly, COW was not associated with overall contact hours, large classes, or personal tutoring. The contributing factors explained 5.1%–8.6% of variance in COW, suggesting they may be meaningful levers for optimising retention. The paper discusses links to existing literature, future research directions, and applied implications for institutions.

Messages to promote physical activity: Are descriptors of required duration and intensity related to intentions to be more active?

Introduction: Mass-media campaigns such as, “Change4Life’ in the UK and “get active America” in the US, promote physical activity (PA) recommendations of at least 150 min/week of moderate-to-vigorous PA (MVPA). We investigated whether different messages used in MVPA campaigns were associated with intention to engage in more MVPA. Materials and Methods: Theory of planned behavior (TPB) constructs; subjective norms, affective attitudes, instrumental attitudes and perceived behavioral control (PBC) were applied to explain the associations between campaign messages and intentions to engage in more MVPA. Results: A total of 1412 UK adults completed an online survey on MVPA and TPB. The sample was 70% female and 93% white with 23% reporting meeting PA guidelines. Participants received one of three messages: A walking message either with or without the 150 min/week threshold (WalkT; WalkNT); a physiological description of MVPA with the 150 min/week threshold (PhysT). ANCOVA examined group differences in intention. Path analysis evaluated mediation by TPB variables. ANCOVA identified lower intentions to increase MVPA in group PhysT relative to WalkT and WalkNT (P < 0.001). PBC mediated this relationship in WalkT (β = 0.014, 95% confidence interval [CI] = 0.004–0.028) whereas affective attitudes mediated this relationship in WalkNT (β = 0.059, 95% CI = 0.006–0.113). Conclusions: Campaigns promoting MVPA guidelines need to choose their messages carefully. Messages which exemplified MVPA through walking were associated with higher intentions to increase MVPA than messages using a physiological description. Further, PBC was enhanced when the 150 min/week threshold was promoted alongside the walking exemplar. Future exemplars should be investigated to inform adults how to meet MVPA guidelines.
