Abstract
OBJECTIVES To examine the long-term validity of the Active Australia Survey in a cardiac rehabilitation population using accelerometry as the reference measure. DESIGN Cohort validation study. METHODS Cardiac rehabilitation participants with coronary heart disease were recruited to a prospective cohort study. Over 7-days, 61 participants wore an ActiGraph ActiSleep accelerometer (1-second epoch, 10-minute bout) and completed the self-administered Active Australia Survey at baseline, 6-weeks, 6 and 12-months. Total daily moderate-to-vigorous physical activity from both methods was compared using Bland-Altman plots and Spearman rank-order correlations. RESULTS Participants tended to over-report moderate-to-vigorous physical activity, with more active participants more likely to over-report moderate-to-vigorous physical activity. There was a good level of agreement between the accelerometer 1-second epochs and Active Australia Survey at all time points (mean bias (ratio) 1.04, 1.16, 1.14, and 1.06, respectively), with weak-moderate correlations (ρ = 0.3-0.48). Conversely, there was a poor level of agreement between the accelerometer 10-minute bouts and Active Australia Survey at all time points (mean bias (ratio) 6.78, 9.09, 6.35, and 5.68, respectively), with weak-moderate correlations (ρ = 0.3-0.52). Agreement between the two measures did not improve over time for both 1-second and 10-minute bout accelerometry data. CONCLUSIONS The Active Australia Survey may be an acceptable self-report measure of moderate-to-vigorous physical activity in cardiac rehabilitation attendees when capturing any time spent in moderate-to-vigorous physical activity. The Active Australia Survey may be useful to routinely monitor physical activity levels over-time in Australian cardiac rehabilitation programs at both individual and group levels.

Association of device-measured physical activity and sedentary behaviour with cardiovascular risk factors, health-related quality-of-life and exercise capacity over 12-months in cardiac rehabilitation attendees with coronary heart disease. BMC Sports Sci Med Rehabil 2022; 14:169. [PMID: 36071477 PMCID: PMC9454132 DOI: 10.1186/s13102-022-00562-7] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2022] [Accepted: 08/26/2022] [Indexed: 11/10/2022]
Abstract
Background Few studies have considered the relationship between risk factors, physical activity and sedentary behaviour in people with heart disease. Here we examine the independent relationship of device-measured physical activity and sedentary behaviour on risk factors, quality-of-life and exercise capacity over 12-months in cardiac rehabilitation attendees. Methods Hospital-based phase II cardiac rehabilitation participants with coronary heart disease were assessed at the start and end of cardiac rehabilitation (6-weeks), 6 and 12-months. Physical activity (moderate-to-vigorous (MVPA), light-intensity (LIPA); min/day) and sedentary behaviour (min/day, bouts, breaks) were measured using an ActiGraph accelerometer. Risk factors included waist circumference, body mass index, systolic blood pressure (SBP), fasting blood lipid and glucose levels, anxiety and depression. Quality-of-life and exercise capacity were also collected. Associations were assessed with Generalized Estimating Equation modeling. Results Sixty-seven participants were included (mean age = 64 (SD 9) years; 81% male). An association was found between higher MVPA and lower high density lipoprotein (p ≤ 0.001). No significant (p ≤ 0.001) associations were found between sedentary behaviour variables and other outcomes. At p < 0.05 several associations were significant. Increased MVPA and LIPA were associated with decreased total cholesterol. Higher MVPA was associated with decreased SBP, whereas higher LIPA was associated with decreased waist circumference and body mass index. Higher sedentary behaviour bouts and breaks were associated with increased total cholesterol, anxiety and depression, and decreased SBP over time. Conclusions Any intensity of physical activity was associated with decreased total cholesterol. Increased LIPA was associated with improved measures of adiposity, while breaking up sedentary behaviour and increasing MVPA may decrease SBP over time. Further investigation of MVPA, LIPA and the distribution of sedentary behaviour is indicated in cardiac rehabilitation attendees to explore their relationship with risk factors.

Comparison of device-based physical activity and sedentary behaviour following percutaneous coronary intervention in a cohort from Sweden and Australia: a harmonised, exploratory study. BMC Sports Sci Med Rehabil 2020; 12:17. [PMID: 32419950 PMCID: PMC7210676 DOI: 10.1186/s13102-020-00164-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2019] [Accepted: 02/20/2020] [Indexed: 11/18/2022]
Abstract
Background Few studies have measured device-based physical activity and sedentary behaviour following a percutaneous coronary intervention (PCI), with no studies comparing these behaviours between countries using the same methods. The aim of the study was to compare device-based physical activity and sedentary behaviour, using a harmonised approach, following a PCI on-entry into centre-based cardiac rehabilitation in two countries. Methods A cross-sectional study was conducted at two outpatient cardiac rehabilitation centres in Australia and Sweden. Participants were adults following a PCI and commencing cardiac rehabilitation (Australia n = 50, Sweden n = 133). Prior to discharge from hospital, Australian participants received brief physical activity advice (< 5 mins), while Swedish participants received physical activity counselling for 30 min. A triaxial accelerometer (Actigraph GT3X/ActiSleep) was used to objectively assess physical activity (light (LPA), moderate-to-vigorous (MVPA)) and sedentary behaviour. Outcomes included daily minutes of physical activity and sedentary behaviour, and the proportion and distribution of time spent in each behaviour. Results There was no difference in age, gender or relationship status between countries. Swedish (S) participants commenced cardiac rehabilitation later than Australian (A) participants (days post-PCI A 16 vs S 22, p < 0.001). Proportionally, Swedish participants were significantly more physically active and less sedentary than Australian participants (LPA A 27% vs S 30%, p < 0.05; MVPA A 5% vs S 7%, p < 0.01; sedentary behaviour A 68% vs S 63%, p < 0.001). When adjusting for wear-time, Australian participants were doing less MVPA minutes (A 42 vs S 64, p < 0.001) and more sedentary behaviour minutes (A 573 vs S 571, p < 0.001) per day. Both Swedish and Australian participants spent a large part of the day sedentary, accumulating 9.5 h per day in sedentary behaviour. Conclusion Swedish PCI participants when commencing cardiac rehabilitation are more physically active than Australian participants. Potential explanatory factors are differences in post-PCI in-hospital physical activity education between countries and pre-existing physical activity levels. Despite this, sedentary behaviour is high in both countries. Internationally, interventions to address sedentary behaviour are indicated post-PCI, in both the acute setting and cardiac rehabilitation, in addition to traditional physical activity and cardiac rehabilitation recommendations.

Validity of the Past-day Adults' Sedentary Time Questionnaire in a Cardiac Rehabilitation Population. J Cardiopulm Rehabil Prev 2020; 40:325-329.

Abstract
PURPOSE Self-report measures of sedentary behavior are easier to use in a clinical setting; yet, no self-report measures of sedentary behavior appear to be validated in cardiac rehabilitation over time. The aim of this study was to assess the validity of the Past-day Adults' Sedentary Time (PAST) questionnaire in a cardiac rehabilitation population over 12 mo. METHODS Seventy-two cardiac rehabilitation participants were recruited to a prospective cohort study. Participants wore an ActiGraph ActiSleep accelerometer (sedentary time <100 counts/min) for 7 consecutive days and completed the self-administered PAST questionnaire at baseline, 6 wk, and 6 and 12 mo. Total daily sedentary time from both methods were compared using Bland-Altman plots and Spearman rank-order correlations. RESULTS Agreement between the 2 measures of sedentary time improved over 12 mo. At 6 and 12 mo, there was a good level of agreement between measures (mean difference between accelerometer and PAST 57 and -0.7 min, respectively), although the dispersion of the differences was wide (95% limits of agreement -428 to 541 and -500 to 498 min, respectively). There were weak correlations between the PAST questionnaire and average accelerometer measured sedentary time at all time points (α = -0.249 to 0.188). CONCLUSIONS Following repeated assessments, the PAST questionnaire may be useful to determine sedentary time in cardiac rehabilitation participants at a group level, with participants appearing to more accurately recall their time spent in sedentary behavior. Further research is indicated to assess the validity of sedentary behavior questionnaires in cardiac rehabilitation, with a combination of objective and self-reported measures currently recommended.

Abstract
BACKGROUND International cardiac rehabilitation guidelines recommend that participants meet public health physical activity guidelines. Few studies have objectively measured how much time cardiac rehabilitation participants spend in physical activity and sedentary behaviour, particularly over the long term. OBJECTIVE The aim of this study was to objectively assess physical activity and sedentary behaviour of cardiac rehabilitation participants over 12 months and determine whether they met the public health physical activity and sedentary behaviour guidelines. METHODS Cardiac rehabilitation participants with coronary heart disease were recruited in a prospective cohort study (n=72). Participants wore an ActiGraph ActiSleep accelerometer for 7 consecutive days at baseline, 6 weeks, and 6 and 12 months to assess daily minutes of moderate-to-vigorous physical activity and sedentary behaviour (<100 counts/min). Other outcomes collected were self-reported physical activity and sedentary behaviour, body mass index, waist-to-hip ratio, lipid profile, blood glucose level, quality of life, exercise capacity, anxiety and depression. RESULTS By intent-to-treat analysis, during the 6-week cardiac rehabilitation program, participants increased their light physical activity (P<0.01), which was maintained up to 12 months. Moderate-to-vigorous physical activity and sedentary behaviour did not change during the 6-week cardiac rehabilitation program but did improve over 6 months (sedentary behaviour decreased [P<0.001], moderate-to-vigorous physical activity increased [P<0.05]), which was maintained up to 1 year. Completion of moderate-to-vigorous physical activity in 10-min bouts did not change over 12 months, nor did the proportion of participants meeting physical activity guidelines (15-21%). Sedentary behaviour remained high throughout (11 hr/day). CONCLUSION Most cardiac rehabilitation participants did not meet the physical activity guidelines during and after a 6-week program up to 12 months. Reducing sedentary behaviour may be a more achievable first-line strategy for cardiac patients, moving participants along the energy expenditure continuum, aiming to increase their physical activity levels over the medium to long term.

Lepp A, Barkley JE. Cell phone use predicts being an "active couch potato": results from a cross-sectional survey of sufficiently active college students. Digit Health 2019; 5:2055207619844870. [PMID: 31019724 PMCID: PMC6463329 DOI: 10.1177/2055207619844870] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2018] [Accepted: 03/28/2019] [Indexed: 12/16/2022] Open
Abstract
Objective “Active couch potato” describes an individual who is sufficiently physically active yet highly sedentary. Cell phones promote activities understood as sedentary behaviors (e.g. watching videos). Research demonstrates that cell phone use is positively associated with sedentary behavior. Although sedentary behavior typically displaces physical activity, no relationship between cell phone use and physical activity has been found. Thus, it is possible that some sufficiently active individuals are also high-frequency cell phone users and therefore highly sedentary. In other words, cell phone use may predict being an “active couch potato” among active people. Testing this hypothesis was the purpose of this study. “Active couch potatoes” are of concern as the negative effects of excessive sedentary behavior are independent of the benefits of physical activity. Methods College students (228) completed validated surveys assessing physical activity, sedentary behavior, and cell phone use. Using a previously validated method, participants were rated as sufficiently active or not based upon their physical activity survey score. Participants who were not sufficiently active were excluded from further analysis resulting in a final sample of 171. These sufficiently active individuals were categorized as “active couch potatoes” if they were also highly sedentary (i.e. sitting for eight or more hours/day). Logistic regression determined if cell phone use predicted being categorized as an “active couch potato.” Results Cell phone use was a significant, positive predictor of being an “active couch potato.” With each additional hour of daily cell phone use, the odds of becoming an “active couch potato” increased by 11.4% (Wald = 5.934, P = 0.015, Exp(B) = 1.114). On average, active couch potatoes used their cell phone 1.7 hours more each day than their sufficiently active but not overly sedentary peers. Conclusion Increased cell phone use was a significant predictor of being an “active couch potato.” Explanations and implications are discussed.
