Comparing Accelerometer and Self-Reported Treatment Effects in a Technology-Supported Physical Activity Intervention

Background and Aims To estimate and compare the change in moderate-to-vigorous physical activity (MVPA) between an accelerometer and technology-supported physical activity (PA) log across a 3-week PA intervention. Method Participants ( N = 204, 77% female, age = 33 ± 11 years, body mass index = 28.2 ± 7.1 kg/m2) were randomized to one of two activity-related intervention arms: (1) increase MVPA intervention or (2) decrease sedentary behavior active control. Participants wore an accelerometer while simultaneously completing a technology-based PA log every day for 5 weeks: a 2-week baseline assessment phase and a 3-week intervention phase. Bivariate linear mixed-effects models and correlations were used to characterize the relationship of MVPA between measurement methods throughout the intervention. Effect sizes were calculated to determine the intervention effect by measurement method. Results At baseline, PA log MVPA was 28 minutes greater than accelerometer-based minutes of MVPA in the active control group. This difference was 35 minutes (95% CI [23.7, 46.1]) greater at follow-up than at baseline measurement in the MVPA intervention group. In the active control group, there was a significant 16-minute (95% CI [6.0, 26.5]) increase between the two measures from baseline to follow-up. The intervention effect size based on the PA log was 0.27 (95% CI [0.14, 0.39]) and 0.42 (95% CI [0.28, 0.56]) when using the accelerometer. Discussion and Conclusions Our results indicate that PA log MVPA and accelerometer MVPA estimate significantly different minutes per day of MVPA. It is important researchers use caution when comparing MVPA intervention outcomes from different measurement methods.

Objectively Measured

Background: Latinas have high rates of sedentary behavior and related health disparities, but it is unknown if interventions to increase physical activity will also reduce sedentary time. The current study examined changes in objectively measured sedentary time among Latinas in a randomized controlled trial of a physical activity intervention. Methods: Spanish-speaking Latinas (N = 202) were randomized to an exercise or wellness group and wore an accelerometer at baseline, 6 months, and 12 months. Results: Participants were sedentary on an average of 8.86 hours per day (SD = 2.60) at baseline. The intervention group had significantly greater increases in sedentary time compared with the control group, with the intervention group engaging in 146 more minutes per week of sedentary time at 6 months and 254 minutes per week of sedentary time at 12 months than the control group (P = .02). The intervention effect on sedentary behavior remained after controlling for moderate to vigorous physical activity. Additionally, time spent in moderate to vigorous physical activity was positively associated with more sedentary time (P = .04). Conclusion: An intervention to increase moderate to vigorous physical activity resulted in greater sedentary time, raising concerns regarding compensation and highlighting the need for interventions to address both physical activity and sedentary behavior to improve public health.

Preschool Aged Children

Purpose: Preschool-aged children, especially girls, have low levels of physical activity that may be influenced through parent role modeling. Evidence for mother–daughter interventions that include preschool-aged children is sparse. The primary purpose of this study was to examine the feasibility of recruitment procedures, protocol compliance, and participant retention for the Mothers and Daughters Moving Together intervention. The secondary aim was to provide initial estimates of the intervention effect on mother–daughter and family physical activity co-participation, moderate to vigorous physical activity, and maternal physical activity enjoyment and support. Method: This nonrandomized feasibility study included mother–daughter (2–5 y) dyads who self-selected into the intervention (n = 21 dyads) or comparison (n = 10 dyads) group. Results: The recruitment rate was 41.9% (31 enrolled/74 interested). Intervention group mother–daughter dyads attended 57% of intervention sessions. Among the whole sample, 70% to 80% of participants (mothers and daughters) had at least 4 valid days of accelerometer data at preintervention and postintervention. The retention rate was 90% (28/31 dyads completed the study). Initial estimates of intervention effect indicated small, positive changes for mother–daughter physical activity co-participation, and maternal physical activity support and enjoyment. Conclusions: This study provides valuable information that should be confirmed using an adequately powered and randomized study design.

Physical Activity Interventions

Background: The aim of this pilot study was to examine the impact of a brief physical activity intervention on adolescents’ subjective sleep quality. Cross-sectional studies indicate that physically active adolescents have better subjective sleep quality than those with more sedentary habits. However, less is known about the effectiveness of physical activity interventions in improving adolescents’ subjective sleep quality. Methods: In a three-week physical activity intervention, four Icelandic upper secondary schools were randomized to either an intervention group with pedometers and step diaries or a control group without pedometers and diaries. Out of 84, a total of 53 students, aged 15−16 years, provided complete data or a minimum of two days step data (out of three possible) as well as sleep quality measures at baseline and follow-up. Subjective sleep quality, the primary outcome in this study, was assessed with four individual items: sleep onset latency, nightly awakenings, general sleep quality, and sleep sufficiency. Daily steps were assessed with Yamax CW-701 pedometers. Results: The intervention group ( n = 26) had significantly higher average step-count ( p = 0.03, partial η2 = 0.093) compared to the control group ( n = 27) at follow-up. Subjective sleep quality improved ( p = 0.02, partial η2 = 0.203) over time in the intervention group but not in the control group. Conclusions: Brief physical activity interventions based on pedometers and step diaries may be effective in improving adolescents’ subjective sleep quality. This has important public health relevance as the intervention can easily be disseminated and incorporated into school curricula.

Sleep And Cognition

Biochemical and neuropsychological changes due to poor sleep may contribute to the development of neurodegenerative disorders, such as dementia. Physical activity is widely thought to improve sleep; however, the optimal intensity/duration of physical activity required is unknown. This 14-week, single-blind study (n=23) investigated the feasibility of a self-directed physical activity intervention in healthy adults using actigraphy and cognitive function measures as primary outcomes. Participants were randomised to a control group (no change in routine) or the intervention group (increased physical activity) and were provided with an actigraphy device to monitor activity. Participants completed daily sleep/activity diaries and three cognitive assessment sessions. Vigorous physical activity increased between baseline and week 3 for the intervention group only, with no identifiable impact on sleep. This change was not sustained at week 12. Performance on an executive function task and delayed visuospatial recall improved from baseline to week 12 for the intervention group only. Contrary to our expectations, increasing light-moderate physical activity was associated with more impaired sleep across all participants. It is clear that the relationships between physical activity, sleep and cognition are complex and require further investigation. We discuss optimal methodologies for clinical trials investigating physical activity and/or sleep interventions targeting cognition.

Background:This study evaluated the effects of gender on response to a behavioral intervention that rewarded increases in physical activity (PA) with increases in access to TV viewing.Methods:We performed a secondary analysis of a clinical trial that randomized 30 overweight or obese, 8- to 12-year-old children to an intervention (8 boys, 6 girls) or control (7 boys, 9 girls) group. Participants wore accelerometers every day for 8 weeks and attended biweekly meetings to download the activity monitors. For the intervention group, accumulating 400 counts of PA on accelerometers earned 1 hour of TV time, which was controlled by a Token TV electronic device. Controls wore activity monitors but had free access to T V.Results:Compared with girls, boys in the intervention group exhibited greater increases in overall daily PA counts (110% versus 40%, P < .05) and minutes per day of moderate-to-vigorous physical activity (MVPA; +18.1 versus +2.7, P < .05). Neither boys nor girls in the control group showed significant changes in overall PA or intensity of PA.Conclusion:Wearing an accelerometer in combination with rewarding PA with TV might be a more effective intervention for increasing overall PA and time spent in MVPA in overweight and obese boys than it is for overweight or obese girls.

Step Counts

Purpose – The purpose of this paper is to ascertain the effect of a physical activity intervention using a combination of Facebook and standing banners on improvements in metabolic syndrome. Design/methodology/approach – In all, 120 (82.8 per cent) government employees with metabolic syndrome completed the programme. A Lifecorder e-STEP accelerometer (Suzuken Company Limited, Nagoya, Japan) was utilized to quantify physical activity. Metabolic syndrome was defined according to “Harmonized” definition at baseline, post-intervention and follow-up. Findings – There were significantly higher step counts in the intervention group as compared to the control group over time. There were significant within-group differences in the step count at the baseline, post-intervention and follow-up assessments (p < 0.001) in both the intervention and control groups. The step count of the intervention group increased by 4,522 steps in the post-intervention assessment compared to the assessment at baseline. The step count of the intervention group in the follow-up assessment was lower than in the post-intervention assessment, but it was still 2,126 steps higher than at baseline. For control group, the difference between the post-intervention assessment and the assessment at baseline was 520 steps per day, while the difference between the follow-up assessment and assessment at baseline was 379 steps per day. The greatest decrease in the percentage of metabolic syndrome was observed in the intervention group, with a reduction of 88.6 per cent in the post-intervention assessment as compared to that at baseline. Research limitations/implications – Future studies should incorporate measures which will be of interest to employers. Greater understanding and assessment of desirable employer-related outcomes are warranted, such as decreased job stress, turnover, absenteeism and improved job satisfaction, productivity and exploration of how these associated with physical activity. Practical implications – The findings show that delivering information on physical activity through an easily implemented and low-cost physical activity intervention via a combination of Facebook and standing banners was successful in improving step counts and metabolic parameters among individuals with metabolic syndrome. Social implications – The findings draw on supporting evidence for advocacy, which is about influencing the larger environment of public policy, and raising awareness of a single programme is insufficient to create lasting social change. Public policy must be shaped in a way that will sustain change across institutions. Originality/value – Despite the well-documented health benefits of physical activity, a growing number of people not achieving the recommended levels of physical activity necessary for good health. Importantly, the study provides a new insight on lifestyle-based physical activity interventions capable of improving step counts and metabolic parameters.

The Impact

Abstract BackgroundThe increase rate seen in Total Hip Arthroplasty (THA) for younger patients has implications for future rehabilitation demands for primary and revision THA surgery. This study aims to determine the impact of a 6-week post-operative rehabilitation program designed for THA patients ≤ 60 years on physical activity (PA) and function compared to age- and a sex-matched control group received usual postoperative care at 12-week post-THA. MethodsIn this quasi-experimental study, a cohort of THA candidates was recruited during their 6-week postoperative visit to their surgeons. The out-patient rehabilitation program consisted of 12 structured exercise classes (2 hrs/class) over 6 weeks. Physical activity was assessed using Sense Wear Pro ArmbandTM [SWA]. Participants completed the Hip Osteoarthritis Outcome Score (HOOS), and THA satisfaction questionnaire before and immediately after the intervention. ResultsThe intervention group took significantly more steps/day at the follow-up compared to baseline. The intervention group had a higher mean change in the number of weekly PA bouts than the control group. Within the intervention groups, all HOOS subscales were significantly higher at the follow-up compared to baseline. ConclusionThe augmented rehabilitation program may have immediate effects on pain relief and symptom reduction for patients (≤60 years) following THA.

Bone Resorption Marker

Introduction: Bone formation marker osteocalcin (OC) and bone resorption marker C-terminal telopeptide of type 1 collagen (CTX) can be used to detect or to monitor the early responses of the skeleton to physical activity. Literature suggests that it is likely that higher body mass index (BMI) has positive effect on bones and can postpone onset of osteoporosis.Aim of the Study: The aim of this study is to:1.Determine the effect of aerobic physical acitivity on OC and CTX in young women2.Investigate correlation of OC, CTX and BMI in young women engaged into structured aerobic excerciseMaterial and methods: Study included 64 healthy young women, aged 19 to 25 years, devided into two groups: intervention group (n=32) and control group (n=32). The study duration was six weeks with follow-up period of four weeks. The intervention group underwent structured aerobic physical activity program for six weeks, but the control group did not receive such program. Level of OC, CTX and BMI were measured at baseline, after 6-week aerobic program, and after 4-week follow up (only intervention group).Results: There was significant increase of OC level after 6-week aerobic program, while level of CTX did not changed. OC level was at its maximum immediately after finishing the program in the participants with normal BMI (p<0.001). There was no statistically significant interaction of BMI and CTX level.Conclusion: Aerobic physical activity increases level of osteocalcin, suggesting that it has positive influence on bone formation in young women, primarily in women with normal BMI.

Physical Activity Duration

Gamification and social incentives are promising strategies to increase the effectiveness of web-based physical activity (PA) interventions by improving engagement. In this study, we designed a PA intervention integrating gamification and social incentives based on the most popular social networking service in China, WeChat. A controlled trial involving 52 Chinese undergraduate students was implemented to evaluate the effectiveness of the intervention. Subjects in the intervention group received a 7-week intervention. PA behavior and related social cognitive variables according to the theory of planned behavior were measured at the baseline and after the intervention. Daily physical activity duration was measured during the intervention. The results showed that PA-related subjective norms, perceived behavior control, and intention, as well as self-reported vigorous physical activity and moderate physical activity in the intervention group, were increased after the intervention, compared with the control group (p <0.05). During the intervention, perceived daily physical activity duration in the intervention group was on the rise, while it declined in the control group (p <0.001). The findings indicate that WeChat-based intervention integrating gamification and social incentives could effectively increase subjectively measured PA and related social cognition among Chinese undergraduate students and that it is a promising way to ameliorate the problem of insufficient PA among youths.

Self Protection

Emotion Focused Training for Self-Compassion and Self-Protection (EFT-SCP) is a novel intervention developed on the basis of the latest findings on self-criticism from Emotion-focused therapy and existing programs designed to cultivate compassion. EFT-SCP is designed to encourage participants to cultivate self-compassion and protective anger as a way of reducing selfcriticism. Our goal was to investigate the effect of this group-based intervention on self-criticism, self-protection, and self-compassion. A total of 73 students were assigned to the EFT-SCP intervention (n=19), no-treatment control (n=34) or to an active control group (n=20). The intervention group met weekly for 1.5 hours and were instructed to incorporate EFT-SCP tasks into their daily life for 12 weeks. Whilst the no-treatment group did not undergo an intervention, the active control group completed an adapted expressive writing task once a week. In addition to the assessment of heart rate variability during imagery tasks, participants also completed self-reported measures of self-compassion and self-criticism before and after the intervention. Compared with both control groups, the intervention group showed a significant increase in heart rate variability following EFT-SCP (during self-critical imagery, P=.049; probability of superiority was .63, and during self-compassionate imagery P=.007; probability of superiority was .62, both effect sizes were medium) and significant decreases in self-criticism (Hated Self P=.017; .34 and Inadequate Self P<.001; .33) and selfuncompassionate responding (P<.001; .39). All three effect sizes were small. Participating in EFT-SCP had a positive effect on psychological and physiological outcomes.
