Stand Up, Students! Decisional Cues Reduce Sedentary Behavior in University Students

Real-Time Vibration Feedback from a Smartphone Application Reduces Sedentary Time but Does Not Increase Physical Activity Among Medical Students

Background: Sedentary behavior is associated with various adverse health outcomes. Medical students often experience high academic demands, leading to increased sedentary time. This study aimed to evaluate the effectiveness of a mobile app providing real-time feedback in reducing total sedentary time and prolonged sedentary bouts and in promoting physical activity among medical students. Methods: Seventy-seven medical students from Jazan University (mean age: 21.4 years; range: 20-25 years) participated in this study. Participants were assigned to either the control group (n = 40) or the intervention group (n = 37). The intervention group received real-time vibration feedback via a mobile app, prompting movement every 30 min of sedentary time, while the control group received no intervention. Sedentary behavior and physical activity levels were assessed using the Activities Completed Over Time in 24 h. Paired t-tests were conducted to examine within-group changes, and a two-way ANOVA was used to assess the interaction effect of time and group on sedentary time and physical activity. Results: After six weeks, the intervention group showed significant within-group reductions in their total sedentary time of 1.82 h (p = 0.01) and prolonged sedentary bouts of 1.91 h (p = 0.001), while the control group had no significant changes. Physical activity levels did not significantly change within either group. The two-way ANOVA revealed that there was no significant change over time between the two groups in their total sedentary time F (1, 75) = 1.590, p = 0.21, prolonged sedentary bouts F (1, 75) = 3.499, p = 0.06, or physical activity F (1, 75) = 0.565, p = 0.45. Conclusions: Real-time feedback from mobile apps resulted in significant within-group reductions in total and prolonged sedentary time among medical students in the intervention group. Low-cost mobile apps providing real-time feedback may be an effective intervention for reducing sedentary behavior among medical students, potentially improving their health and well-being.

Sedentary behaviour in Australian university students: The contribution of study-related sedentary behaviour to total sedentary behaviour

ISSUE ADDRESSED

Seated activities are attributed to increased sedentary behaviour (SB) and adverse health effects, but little is currently known about university students' SB, particularly study-related SB. This study describes the sociodemographic variations of domain-specific SB in regional Australian university students and the contribution of study-related SB to total SB.

METHODS

Self-reported daily SBs from a cross-sectional survey of 451 students were used. Domain-specific and total SB were described within sub-groups, and differences examined using independent t-tests. Multinomial regression was used to examine the association of tertiles of duration in study-related SB with total and other domain-specific SBs.

RESULTS

Study participants were a median age of 21 (19-25 years), mostly female (76%) and represented different years of study. On average, students spent 882 ± 292 min/day in total SB, with most SB occurring in the study, screen time and 'other activity' domains. No sociodemographic variations were found in total SB, but significantly higher study-related SB were reported by students studying full time (p < .001) and who moved from their family home to study (p < .022). Study-related SB contributed 36% of total SB, with students most sedentary during study having the highest total SB.

CONCLUSIONS

This study suggests university students have high levels of SB, primarily in the domains of study, screen time and other activities. SB reduction strategies in universities and targeting screen time, across various sociodemographic groups (e.g., gender, university enrolment status, and living arrangements), may be important in reducing SB in university students. SO WHAT?: University students are highly sedentary and should be included in SB programs especially students studying full time and those who moved from their family home in the study domain.

Effective management of sedentary behavior among Indian university students: An empirical exploration into health-related behavior

BACKGROUND

The past few years have witnessed a notable rise in sedentary tendencies, unveiling a modern era of prolonged stillness and diminished physical engagement. This study sought to assess the feasibility of a digital health intervention (DHI) to reduce overall sedentary behavior among university students. The study also identifies distinct subgroups within Indian universities that exhibit a heightened propensity for engaging in unhealthy behaviors.

MATERIALS AND METHODS

The research design used was a quasi-experimental (pre-post) design. A total of 500 participants were selected using a simple randomized sampling method (250 belonging to the control group and 250 belonging to the experimental group). These participants actively engaged in the study for 2 weeks. The participants completed the Sedentary Behavior Questionnaire (SBQ) before the intervention to evaluate their level of sedentary behavior. To evaluate the impact of the intervention on subjectively measured sedentary behavior, statistical analyses were conducted using the paired-samples t-test and analysis of covariance (ANCOVA) with the post hoc Bonferroni test.

RESULTS

The findings demonstrated a significant t-value of sedentary behavior for the entire group, with t(249) = 4.88, P < .05. Furthermore, the F-value of 28.787 indicated a statistically significant difference in the sedentary behavior between the experimental and control groups. When considering female university students specifically, the t-value for sedentary behavior was significant at t(105) = 3.22, P < .05, and for male university students, the t-value for sedentary behavior was found to be significant at t(143) = 3.69, P < .05.

CONCLUSION

Smartphone-based health interventions targeting sedentary behavior reduction demonstrated promising outcomes in facilitating health behavior change among university students.

To move or not to move while on campus: Examining the influence of others

OBJECTIVE

To examine the influence of dynamic and trending descriptive norms on increasing physical activity and decreasing the sedentary behaviors of university students while on campus.

PARTICIPANTS

One-hundred fifty-six university students from a Canadian university completed this study.

METHODS

Participants were randomly assigned to receive one of four online messages containing normative information about the on-campus behavior of university students. On-campus physical activity and sedentary behavior were measured pre- and post-message.

RESULTS

The results revealed that students exposed to the trending norm reported a greater decrease in sedentary behavior than students in the control condition, p = .007.

CONCLUSION

Results provide preliminary experimental evidence that trending norm messages may serve to decrease the sedentary behavior of students while on campus.

Promotion of Physical Activity Among University Students With Social Media Or Text Messaging: A Systematic Review

Regular physical exercise lowers the risk of all-cause mortality and various chronic diseases. New technologies, such as smartphones and social media, have been used successfully as health promotion tools in college populations. The purpose of this study was to conduct a systematic review of studies examining the effectiveness of interventions that used modern technologies, as with social media or text messaging, to promote physical activity or reducing sedentary behavior in college students. The systematic review was conducted on the PubMed and SCOPUS databases, considering studies published from 2012 to 2022. For a total of 19 articles selected, an evidence table was drawn up, and the quality of the studies was assessed using the PRISMA checklist. The interventions differed enormously in design, from the strategies implemented to the types of outcome considered. Fifteen of the 19 studies demonstrated an improvement in participants' physical activity levels, 3 studies found no such improvement, and 1 reported a worsening of baseline activity levels. Interventions to improve college students' physical activity levels through the use of social media and/or text messaging tend to be effective. However, many factors can influence the effectiveness of such interventions. For example, a gender-related difference emerged in student participation, and the interventions proved more effective if they were accompanied by the creation of social groups.

Prevalence of health risk behaviours related to non-communicable diseases amongst South African university students: a systematic review

BACKGROUND

Engagement in risk behaviours adopted during university continues after graduation, increasing the risk of non-communicable diseases (NCDs). This systematic review aimed to investigate the prevalence of NCD risk behaviours amongst South African university students.

METHODS

PubMed and Scopus databases were searched (January 1990-April 2022) for studies investigating alcohol consumption, cigarette smoking, inadequate consumption of fruits and vegetables and physical inactivity. Study qualities were assessed with the Joanna Briggs Institute critical appraisal and levels of evidence checklists. An overall prevalence percentage was obtained for each risk behaviour.

RESULTS

A total of 50 studies (n = 26 624 students) were included. A range of 44.8-75.0% of students consumed inadequate servings of fruits and vegetables. Just over 54% consumed alcohol (95% confidence intervals [95%CI]:54.0-55.5%). A significantly higher percentage of males (44.2%) than females (25.8%) drank heavily (P < 0.001). Approximately one-third (34.8%, 95%CI:33.4-36.3%) were sedentary and 39.0% (95%CI:37.5-40.4%) were insufficiently active. Almost one-fifth (17.9%, 95%CI:17.3-18.5%) smoked cigarettes, being significantly more prevalent amongst males (21.8%) than females (13.5%) (P < 0.001). A total of 10% smoked 1-10 cigarettes/day and 1.2% smoked >10 cigarettes/day.

CONCLUSION

High percentages of South African students eat inadequate servings of fruits and vegetables, consume alcohol are physically inactive and smoke cigarettes. South African universities should implement screening measures and health campaigns.

Videos using different message strategies to promote the interruption of sedentary behavior in university students during online lectures - A pilot study

Background

Sedentary behavior (SB) is highly prevalent among university students and has increased during COVID-19 pandemic. As SB is associated with negative health outcomes, appropriate prevention measures in the university setting are needed.

Objective

This pilot study aimed at investigating the effects of videos using different message strategies to interrupt SB in the collective of university students during online lectures.

Methods

During online lectures, university students (N = 96) were shown one of three videos on the interruption of SB. The videos differed in their message strategies with regard to evidence type (statistical vs. narrative) and vividness (static vs. animated images). Demographics, health variables (SB intentions, SB attitudes) and selected media reception variables (identification, homophily, counterarguing) were examined as possible influence factors on the interruption of SB evoked by watching the video.

Results

Approximately half of the students interrupted sedentary behavior during watching the videos and students of the older age group (cut-off: median = 22 years) interrupted SB significantly more often (p = 0.046). The interruption of SB was predicted by SB intentions (p < 0.05). Identification with characters significantly predicted the intentions to reduce SB (p < 0.001), with a large effect of the overall regression model (R2corr = 0.47).

Conclusion

Considering the increased digitalization in general and restrictions due to COVID-19 pandemic, videos seem to be a useful tool to interrupt SB among university students during online lectures. Narrative formats could facilitate the intention to reduce SB, which in turn could have a positive impact on the interruption of SB. However, further research on effective communication and message strategies is needed.

Classroom Movement Breaks and Physically Active Learning Are Feasible, Reduce Sedentary Behaviour and Fatigue, and May Increase Focus in University Students: A Systematic Review and Meta-Analysis

Background: University students are mostly sedentary in tertiary education settings which may be detrimental to their health and learning. This review aimed to examine the feasibility and efficacy of classroom movement breaks (CMB) and physically active learning (PAL) on physical and cognitive outcomes in university students in the tertiary setting. Methods: Five electronic databases (MEDLINE, CINAHL, Embase, PsychINFO, and PubMed) were searched for articles published up until November 2021. Manual searching of reference lists and citation tracking were also completed. Two reviewers independently applied inclusion and exclusion criteria and completed quality assessment. Articles were included if they evaluated CMB or PAL interventions delivered to university students in a tertiary setting. Results: Of the 1691 articles identified, 14 studies with 5997 participants met the inclusion criteria. Average study quality scores were poor for both CMB and PAL studies. CMBs and PAL are feasible in the tertiary setting and increase physical activity, reduce sedentary behaviour, increase wellbeing, and reduce fatigue in university students. In addition, CMBs increased student focus and attention in class and PAL had no detrimental effect on academic performance. Conclusions: University educators should feel confident in introducing CMB and/or PAL interventions into their classes to improve student health and wellbeing.

University students' knowledge, self-efficacy, outcome expectations, and barriers related to reducing sedentary behavior: a qualitative study

ObjectiveTo explore university students' knowledge, self-efficacy, outcome expectations, barriers and ideas related to reducing sedentary behavior using a qualitative approach. Participants: Nineteen students from a Canadian university participated. Methods: Four focus groups were conducted. Discussions were recorded, transcribed, and coded to identify categories and themes. Results: Some students lacked knowledge of the concept, but most were generally aware of health risks associated with sedentary behavior. Most students were confident they could reduce sedentary behavior, but felt it would be unlikely they would actually do so because: (a) it is not a priority, (b) the health consequences are distal, (c) increasing standing and light-intensity activity would not provide meaningful health benefits, and (d) class schedules/norms/infrastructure encourage sitting and are not under their control to change. Conclusion: Findings from this study may help inform intervention strategies aimed at decreasing excessive sedentary behavior among university students.

Internet use and health in higher education students: a scoping review

The amount of time spent online has increased over the last decade among higher education students. Students engage in online activities related to studies, work, leisure, entertainment and electronic services (e-services) use. The Internet is also used for health-related matters. The increase in the use of the Internet has influenced students' health, especially mental and physical health and well-being. This scoping review scrutinizes the literature between 2015 and 2020 (N = 55) on the association between Internet use and health in higher education students. A methodological framework, outlined by Arksey and O'Malley, was applied to conduct this review. Systematic searches were carried out in the CINAHL, PubMed and Scopus databases and in the available grey literature. For the data, a thematic analysis by Braun and Clarke was utilized. Two major themes of 'Health-promoting Internet use' and 'Health-threatening Internet use' emerged and are described in this review.

Feasibility of Reducing and Breaking Up University Students' Sedentary Behaviour: Pilot Trial and Process Evaluation

Background: Accumulating high levels of sedentary behaviour has been linked to poor health outcomes. This study examined the feasibility and preliminary, short-term effects of a theory-based intervention aimed at reducing total and prolonged sedentary behaviour in University students.

Design: A quasi-experimental (pre-post) pilot study. Methods: Nine ambulatory undergraduate students (Mean age = 22 ± 2.32) participated in a one-on-one session, including an educational component around the health effects of sedentary behaviour and three distinct activities (feedback, “pros and cons” exercise, and suggested behaviour change strategies). In addition, automated daily text messages targeting sedentary behaviour were sent for 6 days (four messages per day at fixed intervals). The Behaviour Change Wheel framework guided the intervention design process. Outcomes were assessed over 6 days in pre- and post-intervention periods and included accelerometer-based (activPAL) and self-reported (Nightly-Week-U) total sedentary time, as well as accelerometer-based number of steps and prolonged sedentary time. Students completed a process evaluation interview upon completing the trial.

Results: From pre- to post-intervention, there was a significant reduction in accelerometer-based total and prolonged sedentary time during weekend days. In addition, there was a significant increase in accelerometer-based standing time and stepping during weekend days. There were no statistically significant changes in accelerometer-based sedentary time, standing time or number of steps during weekdays. Process evaluation results indicated that the intervention and its assessment is feasible. Reductions in sedentary time were likely to be mediated by positive changes in the student's reflective and automatic motivation.

Conclusions: Findings from this small, short-term intervention suggest that a single one-on-one session, together with automated text messages, may help University students reduce sedentary behaviour and enhance movement during weekend days. Additional strategies to maximise the intervention effects are discussed (e.g., establishing a collaboration with University staff, introducing sit-to-stand desks, and/or facilitating social support). A randomised control trial assessing sedentary behaviour over a longer period is needed to adequately study the intervention's effectiveness.

College Classroom Instructors Can Effectively Promote Standing among Students Provided with Standing Desks

Standing desks may reduce sedentary behaviors in college students. Students at one mid-size urban university in the Midwestern United States were randomized into intervention (n = 21) and control groups (n = 27) to assess standing time when given access to standing desks. The intervention group received visual and oral instructor prompts to stand, while the control received no prompts during a 50 min lecture. All students were provided with adjustable tabletop standing desks. ActivPAL accelerometers measured sitting and standing time. A brief survey assessed student preferences, including facilitators and barriers to standing. Mean standing time was greater in the intervention vs. control group (26 vs. 17 min, p = 0.023). Students tended to stand in the corners and edges of the room. Main facilitators for standing included to break up sitting, reduce back pain, and increase attention and focus; main barriers were not wanting to distract others or be the only one standing. In total, 87.5% of intervention group participants found five prompts to stand were adequate. Students increased standing time in class when provided with standing desks and instructor prompts to stand. Findings can inform the layout of classrooms and when and how to promote standing desks during lectures.

A combined health action process approach and mHealth intervention to reduce sedentary behaviour in university students - a randomized controlled trial

Objective: This investigation evaluated the effectiveness of a Health Action Process Approach (HAPA) based planning intervention augmented with text messages to reduce student-related sitting time (primary outcome) and increase specific non-sedentary behaviours. Relationships between the HAPA volitional constructs and sedentary and non-sedentary behaviours were also explored. Design: University students (M_age = 21.13 y; SD = 4.81) were randomized into either a HAPA intervention (n = 28) or control (n = 33) condition. Main Outcome Measures: School-related sitting time, time spent in specific non-sedentary behaviours and HAPA volitional constructs were assessed at baseline, weeks 2, 4, 6 (post-intervention) and 8 (follow-up). Results: Significant group by time interaction effects favouring the intervention group were found for sitting time (p = 0.004, ɳ_p² = 0.10), walking time (p = 0.021, ɳ_p² = 0.06) and stretching time (p = 0.023, ɳ_p² = 0.08), as well as for action planning (p < 0.001, ɳ_p² = 0.17), coping planning (p < 0.001, ɳ_p² = 0.20) and action control (p < 0.001, ɳ_p² = 0.20). Significant correlations (p < 0.05) were also found between the HAPA constructs and sitting-related outcomes. Conclusions: Combining a HAPA-based planning intervention with text messages can reduce student-related sitting time in university students.

A Qualitative Study of the Feasibility and Acceptability of Implementing 'Sit-To-Stand' Desks in Vocational Education and Training

While it has been shown that interrupting a person’s sedentary behaviour has the potential to improve cognitive, physical and mental health, a large part of time that students spend in school is sedentary. As research has shown that approximately 80% of vocational education and training (VET) students have an unhealthy sedentary lifestyle, implementing “sit-to-stand” (StS) desks could interrupt sedentary behaviour and promote healthier behaviour. Therefore, the acceptability and feasibility of using such desks in the VET setting should be investigated. Using semi-structured focus group interviews analysed via deductive content analysis, the opinions of 33 students for the following topics were assessed: (1) usage of the standing option of the desks (2) reasons for standing in class (3) experienced effect of standing behind the desk, and (4) fostering future StS desks usage. Although VET students are aware of the potential benefits of using StS desks, they need to be actively stimulated and motivated by teachers to use them. In addition, time is needed to get into the habit of standing. Thus, for successful implementation of StS desks in the VET setting, all stakeholders (i.e., students, teachers, schoolboards) should be actively involved in stimulating the healthy behaviour of VET students.
