Pilot study of a cell phone-based exercise persistence intervention post-rehabilitation for COPD. (6/483)

OBJECTIVE: To determine the feasibility and efficacy of a six-month, cell phone-based exercise persistence intervention for patients with chronic obstructive pulmonary disease (COPD) following pulmonary rehabilitation. METHODS: Participants who completed a two-week run-in were randomly assigned to either MOBILE-Coached (n = 9) or MOBILE-Self-Monitored (n = 8). All participants met with a nurse to develop an individualized exercise plan, were issued a pedometer and exercise booklet, and instructed to continue to log their daily exercise and symptoms. MOBILE-Coached also received weekly reinforcement text messages on their cell phones; reports of worsening symptoms were automatically flagged for follow-up. Usability and satisfaction were assessed. Participants completed incremental cycle and six minute walk (6MW) tests, wore an activity monitor for 14 days, and reported their health-related quality of life (HRQL) at baseline, three, and six months. RESULTS: The sample had a mean age of 68 +/-11 and forced expiratory volume in one second 18% predicted. Participants reported that logging their exercise and symptoms (FEV(1)) of 40 +/- was easy and that keeping track of their exercise helped them remain active. There were no differences between groups over time in maximal workload, 6MW distance, or HRQL (p > 0.05); however, MOBILE-Self-Monitored increased total steps/day whereas MOBILE-Coached logged fewer steps over six months (p =0.04). CONCLUSIONS: We showed that it is feasible to deliver a cell phone-based exercise persistence intervention to patients with COPD post-rehabilitation and that the addition of coaching appeared to be no better than self-monitoring. The latter finding needs to be interpreted with caution since this was a purely exploratory study. TRIAL REGISTRATION: ClinicalTrials.gov (NCT00373932).  (+info)

Characterizing recovery of sleep after four successive night shifts. (7/483)

The purpose of this study was to characterize the recovery pattern of sleep following simulated, four successive night shifts in ten healthy men (22.9 + or - 3.2 yr). Poor sleep was defined as sleep efficiency of 80% or lower as determined actigraphically. The results showed that four (rapid, slow, pseudo, and incomplete) patterns of sleep recovery were observed over three recovery sleep periods. The rapid and slow recovery pattern represented immediate and slow return to baseline level prior to the nightshifts, respectively. The pseudo recovery pattern demonstrated poor sleep at the 3rd recovery sleep period, despite transient recovery at the 2nd sleep period. The incomplete recovery pattern was characterized by consistently poorer sleep during the entire recovery period. The correlation analysis indicated that sleep habits (bed time and variation of wake time) prior to the experiment were significantly related to the recovery patterns, rather than performance and alertness during the night shifts.  (+info)

Sex differences in subjective and actigraphic sleep measures: a population-based study of elderly persons. (8/483)

STUDY OBJECTIVES: To investigate and explain sex differences in subjective and actigraphic sleep parameters in community-dwelling elderly persons. DESIGN: Cross-sectional study. SETTING: The study was embedded in the Rotterdam Study, a population-based study. PARTICIPANTS: Nine hundred fifty-six participants aged 59 to 97 years. INTERVENTIONS: N/A. MEASUREMENTS AND RESULTS: Participants wore an actigraph and kept a sleep diary for an average of 6 consecutive nights. Subjective sleep quality was assessed with the Pittsburgh Sleep Quality Index. Unadjusted sex differences in sleep parameters were assessed with t tests. Women reported shorter total sleep time, a less favorable sleep-onset latency, lower sleep efficiency, and worse global sleep quality, as compared with men. When assessed with actigraphy, however, women were found to have longer and less-fragmented sleep than men. Sex differences in diary-reported sleep duration and other subjective sleep parameters were attenuated by adjustment for marital status, the use of sleep medication, and other covariates, but all sex differences remained significant in a multivariate-adjusted model. Sex differences in actigraphic sleep parameters were barely attenuated by multivariate adjustment, although the shorter actigraphically measured sleep duration in men was partly explained by their higher alcohol consumption. Some covariates (eg, sleep medication) had a different relationship with diary-reported or actigraphic total sleep time in men and women. CONCLUSIONS: If assessed by diary or interview, elderly women consistently reported shorter and poorer sleep than elderly men. In contrast, actigraphic sleep measures showed poorer sleep in men. These discrepancies are partly explained by determinants of sleep duration, such as sleep medication use and alcohol consumption.  (+info)

The strength of the study is the combined use of mechanical setup with free living confirmation of the comparison. Furthermore, we used different batches of the same Actigraph generation and the newer activity monitors were randomly picked among more than 400 monitors compiled by three batches (bought at three different time points in the period 2009-2010). We also used multiple amplitudes of displacement within the range of displacement observed in human movement [27]. Taken together this increases the generalizability of our findings to other batches of Actigraphs and the performance within the displacement amplitude in humans.. The study also had some limitations. The activity monitors were acquired from different study centers and have been used by several different field investigators. Therefore we do not have complete knowledge of service history and frequency of use. To rule out batch differences we reran the protocol using six GT3X monitors randomly picked from an independent batch and ...

There is limited evidence on the prospective association of time spent in activity intensity (sedentary (SED), moderate (MPA) or vigorous (VPA) physical activity) and dietary intake with adiposity indicators in young people. This study aimed to assess associations between (1) baseline objectively measured activity intensity, dietary energy density (DED) and 4-year change in adiposity and (2) 4-year change in activity intensity/DED and adiposity at follow-up. We conducted cohort analyses including 367 participants (10 years at baseline, 14 years at follow-up) with valid data for objectively measured activity (Actigraph), DED (4-d food diary), anthropometry (waist circumference (WC), %body fat (%BF), fat mass index (FMI), weight status) and covariates. Linear and logistic regression models were fit, including adjustment for DED and moderate-to-vigorous physical activity. Results showed that baseline DED was associated with change in WC (β for 1kJ/g difference: 0·71; 95% CI 0·26, 1·17), ...

An emerging evidence base suggests that SSD is related to food intake. Among factory workers in Japan, SSD was associated with more snacking between meals, more irregular eating habits, less consumption of vegetables, and a greater preference for strongly flavored food.49 In the United States, a study of 459 postmenopausal women enrolled in the Womens Health Initiative examined relationships between dietary records and sleep diary and actigraphy variables.50 This study showed that SSD, measured objectively with actigraphy, was strongly associated with higher intakes of many dietary fat-related variables. ...

Neuropsychiatric symptoms form part of the clinical picture of Alzheimers disease (AD) and other dementias. Irrespective of the severity of the disease, the most frequently encountered symptom is apathy. Apathy is increasingly diagnosed in patients with neurological and psychiatric conditions. Apathy is a disorder of motivation, defined as the direction, intensity and persistence of goal-directed behaviour. Most of the current descriptions acknowledge this point and consider apathy in terms of a lack of goal-directed behaviour, cognition or emotion. The classical neuropsychiatric symptom assessments are subjective structured interview-based, using input from the caregiver and/or the patient. New technologies are likely to provide us with a more objective measure. An example is ambulatory actigraphy, consisting of a piezoelectric accelerometer designed to record arm movement in three dimensions.. The aim of the present study is to assess using actigraphy and video recording signal, AD patients ...

JCSM - A Quantitative Approach to Distinguishing Older Adults with Insomnia from Good Sleeper ControlsJCSM - A Quantitative Approach to Distinguishing Older Adults with Insomnia from Good Sleeper Controls
The present study evaluated quantitative sleep criteria to distinguish individuals with insomnia from good sleepers using two assessment methods. Sleep diary measures produced areas under the curves (AUC) in the high range (0.84-0.97), whereas actigraphy performed poorly at discriminating the two groups (AUC 0.58-0.61). The Youden Index identified SOL = 17.7 minutes, WASO = 20.7 minutes, SE awake = 92.1%, SE OOB = 83.8%, and TST = 388.1 minutes as the sleep diary measures that yielded the highest sensitivity and specificity values, with diary-measured SE awake performing best at differentiating the groups. Our study appears to be the first to examine quantitative sleep thresholds using sleep diary and actigraphy among a sample of older adults who were not required to meet specific quantitative severity thresholds for entry into the study. The absence of such entry criteria limits the circularity of the findings based on study entry criteria.. Given that actigraphy is more costly than diary ...

Study Design and Patient Selection. Our main hypothesis is that elevated circulating levels of tumor-associated cytokines could significantly alter the QOL of cancer patients through the production of circadian clock dysfunction.. A prospectively studied population of 200 consecutive metastatic colorectal cancer patients referred for systemic chronochemotherapy at Paul-Brousse Hospital, Villejuif, France served as the index population as previously reported (5). Before receiving chronochemotherapy, these patients had rest/activity monitoring with wrist actigraphy and serum cortisol rhythm assessment as part of their initial work up. The analysis of the rest/activity records allowed the ranking of the patients according to r24, a robust index of the circadian rhythmicity in activity (see below). From these 200 patients, 80 were selected based upon r24 ranking. Forty patients in the top quartile displayed near normal circadian rhythm (group I) and 40 other patients in the lowest quartile had ...

Introduction: This study examined the equivalency of sleep estimates from Axivity, GENEActiv, and ActiGraph accelerometers worn on the nondominant and dominant wrists and with and without using a sleep log to guide the algorithm. Methods: 47 young adults wore an Axivity, GENEActiv, and ActiGraph accelerometer continuously on both wrists for 4-7 days. Sleep time, sleep window, sleep efficiency, sleep onset, and wake time were produced using the open-source software (GGIR). For each outcome, agreement between accelerometer brands, dominant and nondominant wrists, and with and without use of a sleep log, was examined using pairwise 95% equivalence tests (±10% equivalence zone) and intraclass correlation coefficients (ICCs), with 95% confidence intervals and limits of agreement. Results: All sleep outcomes were within a 10% equivalence zone irrespective of brand, wrist, or use of a sleep log. ICCs were poor to good for sleep time (ICCs ≥ .66) and sleep window (ICCs ≥ .56). Most ICCs were good ...

Actigraphy Movement Count per Hour:Subjects will be asked to wear an actigraphy monitor on each wrist for the duration of the 14-day study. These monitors appear and function similarly to a wristwatch. The actigraph provides a continuous measure of wrist activity and may be used to quantify nocturnal scratching behavior. A piezoelectric accelerometer records the integration of intensity, amount, and duration of stimuli in all 3 dimensions of wrist movement. Measurements are taken at 32 Hz and a summation value is recorded at the end of each 30-second epoch. The number of 30-second epochs with movement (in which acceleration was detected irrespective of the magnitude of the acceleration) is recorded and summed to give a movement score. This is divided by the duration of time in bed to produce a movement count per hour, which is a sensitive quantitative measure of scratch-associated activity ...

This study aimed to examine the validity of a range of consumer-level activity monitors across a range of variables in free-living conditions. In general, the consumer-level devices were highly accurate in measurement of steps, and quite accurate for sleep quantity. However, measures of TDEE and MVPA were less accurate, in general demonstrating moderate to strong correlations with the research-grade accelerometers, but often large MADs. Within each activity construct, the validity of the consumer-level devices varied markedly. Across the domains, the One, Zip and Pulse generally performed strongly.. Steps were generally counted with a high degree of accuracy by the consumer-level activity monitors, though two devices substantially undercounted steps (MADs of 10% for Shine and 26% for Fuelband) and hence underperformed compared to conventional pedometers (such as Yamax; [29]). The findings of the current study, favouring the Fitbit activity monitors, concur with other studies which have similarly ...

Objective: To validate and compare the accuracy of energy expenditure (EE) and step counts measured by ActiGraph accelerometers (ACT) at dominant and nondominant wrist and hip sites. Methods: Thirty young adults (15 females, age 22.93 ± 3.30 years) wore four ActiGraph wGT3X accelerometers while walking and running on a treadmill for 7 min at seven different speeds (1.7, 2.5, 3.4, 4.2, 5.0, 5.5, and 6.0 mph). The EE from each ACT was calculated using the Freedson Adult equation, and the worn on the wrist option was selected for the wrist data. Indirect calorimetry and manually counted steps were used as criterion measures. Mean absolute percentage error and two one-sided test procedures for equivalence were used for the analyses. Results: All ACTs underestimated the EE with mean absolute percentage errors over 30% for wrist placement and over 20% for hip placement. The wrist-worn ACTs underestimated the step count with mean absolute percentage errors above 30% for both dominant and nondominant ...

The aims of this paper were to provide an overview of available activity monitors used in research in patients with heart failure and to identify the key criteria in the selection of the most appropriate activity monitor for collecting, reporting, and analysing physical activity in heart failure research. This study was conducted in three parts. First, the literature was systematically reviewed to identify physical activity concepts and activity monitors used in heart failure research. Second, an additional scoping literature search for validation of these activity monitors was conducted. Third, the most appropriate criteria in the selection of activity monitors were identified. Nine activity monitors were evaluated in terms of size, weight, placement, costs, data storage, water resistance, outcomes and validation, and cut-off points for physical activity intensity levels were discussed. The choice of a monitor should depend on the research aims, study population and design regarding physical ...

Sleep disturbance has been found to trigger a stress response with a subsequent activation of the psychoneuroimmunological (PNI) pathway associated with adverse health outcomes. This study aimed to assess the association among selected PNI biomarkers, sleep disturbances, and adverse health outcomes (depressive symptoms, physical symptoms). A stratified, quota sample (14 poor sleepers and 15 good sleepers) was drawn from a pool of healthy college women from a larger scale of study. The participants reported their sleep, stress, depressive, and physical symptoms. Wrist actigraphy was used to collect objective sleep data, and the Enzyme-Linked ImmunoSorbent Assay was used to assess PNI biomarkers. Poor sleep quality, higher stress perception, elevated serum serotonin, and lower serum interleukin-10 explained 75.3% of the variances for the depressive symptoms. Poor sleep quality along with delayed peak activity rhythms accounted 31.4% of the physical symptoms. High serotonin and tumor necrosis factor-α

Background: Epidemiologic studies examining physical activity have used self-report or the preferred objective measurement devices of pedometers or accelerometers. NHANES 2003-2004 used remuneration, in-person and express mail methods to obtain accelerometer data from 7176 individuals with 4867 (68%) providing 4+ valid days of wear. Herein we describe the experience of another national epidemiologic study that used telephone and regular mail to obtain accelerometer data.. Methods: This is an ancillary study to REGARDS, a national, population-based, longitudinal study of 30,239 blacks and whites, aged , 45 years, enrolled January 2003-October 2007. Participants were recruited from communities across all 48 of the lower United States, and include residents of 1,855 of the 3,033 US counties. Baseline evaluations were conducted through computer-assisted telephone interview (CATI), self-administered questionnaires, and an in-home visit. Participants are followed by CATI every 6 months. Starting with ...

Current StudentsCurrent Students
This unit introduces students to the field of physical activity and health. The unit begins by exploring the benefits of physical activity and risks of sedentary behaviour and then moves on to understand physical activity participation. In this regard, common theories of behaviour change are explored as are key correlates of physical activity participation. An introduction to physical activity interventions is provided as is an introduction to the importance of physical activity in the lives of specific population sub-groups including older adults and underserved populations. Throughout the unit, students are required to source and reflect on high quality evidence in particular to design an appropriate and safe physical activity program that addresses known barriers to participation and fosters adoption and maintenance.. ...

The relationship between engagement in physical activity and the development of motor competence (MC) is considered to be reciprocal and dynamic throughout childhood and adolescence. The 10-month follow-up study aimed to explore this reciprocal relationship and investigated whether the relationship is mediated by the corresponding self-perception of MC (PMC).; A total of 51 children aged between 10 and 11 years (M = 10.27 [0.45]) participated in the study (52.9% boys, 47.1% girls). As an indicator for physical activity, the average vigorous physical activity (VPA) per day was measured by ActiGraph accelerometers. Two aspects of MC and PMC were recorded: self-movement and object movement. Saturated pathway models in a cross-lagged panel design with 2 measurement points were analyzed.; Reciprocal and direct relationships between VPA and MC object movement respectively MC self-movement were not found in longitudinal analyses with PMC as a mediator. Indirect effects of MC at t1 on VPA at t2 via PMC ...

Sleep disturbance in post-traumatic stress disorder (PTSD): a systematic review and meta-analysis of actigraphy studiesSleep disturbance in post-traumatic stress disorder (PTSD): a systematic review and meta-analysis of actigraphy studies
European Journal of Psychotraumatology. Catrin Lewis, Katie Lewis, Neil Kitchiner, Samantha Isaac , Ian Jones & Jonathan I. Bisson. https://doi.org/10.1080/20008198.2020.1767349. Abstract. Background: Sleep disturbance has been described as a hallmark symptom of posttraumatic stress disorder (PTSD). Although there are robust findings of self-reported sleep disturbance in PTSD, evidence of sleep disturbance measured using actigraphy is less certain.. Objective: To conduct a systematic review and meta-analysis to determine whether there are any significant differences between individuals with and without PTSD in actigraph-derived sleep measures.. Method: Case-control studies comparing participants with current PTSD to those without PTSD were eligible for inclusion. Sleep parameters of interest were: (1) total sleep time; (2) sleep onset latency; (3) wake after sleep onset (WASO); and (4) sleep efficiency. Data were meta-analysed as standardised mean differences (SMDs) and potential sources of ...

Genetic Variants in Circadian Rhythm Genes and Self-Reported Sleep Quality in Women with Breast CancerGenetic Variants in Circadian Rhythm Genes and Self-Reported Sleep Quality in Women with Breast Cancer
Previous studies have investigated genetic markers of sleep in the general population using circadian candidate gene and genome wide association (GWA) study designs. The effects of PER3 variants, especially the variable number tandem repeats (VNTR), have been associated with many phenotypes including diurnal preference and sleep loss/circadian misalignment. In our study we did not find an association of the VNTR with sleep quality; however, this lack of replication may be due to the small size of the current study. In a candidate gene study, ARNTL (rs3816358) and NPAS2 (rs3768984) were associated with later actigraphic sleep and wake onset time in an elderly male population (n = 2,527) [38]. ARNTL was also found to be associated with sleep duration in a GWA study, though at a loci 40kb upstream of the gene, rs41348446 [39]. We also found associations between ARNTL and NPAS2 with sleep quality, however at different loci than previous studies.. Most variants found in this study are located in ...

Abnormalities in sleep and circadian rhythms are central features of bipolar disorder (BP), often persisting between episodes. We report here, to our knowledge, the first systematic analysis of circadian rhythm activity in pedigrees segregating severe BP (BP-I). By analyzing actigraphy data obtained from members of 26 Costa Rican and Colombian pedigrees [136 euthymic (i.e., interepisode) BP-I individuals and 422 non-BP-I relatives], we delineated 73 phenotypes, of which 49 demonstrated significant heritability and 13 showed significant trait-like association with BP-I. All BP-I-associated traits related to activity level, with BP-I individuals consistently demonstrating lower activity levels than their non-BP-I relatives. We analyzed all 49 heritable phenotypes using genetic linkage analysis, with special emphasis on phenotypes judged to have the strongest impact on the biology underlying BP. We identified a locus for interdaily stability of activity, at a threshold exceeding genome-wide ...

Changes in Physical Activity, Physical Function and Cognitive Function with Transition to Retirement LivingChanges in Physical Activity, Physical Function and Cognitive Function with Transition to Retirement Living
Physical activity is associated with slower physical and cognitive decline with aging. However, there are many barriers to physical activity among community-dwelling older adults. Retirement living may facilitate physical activity by reducing health, social, and environmental barriers for seniors. The purpose of this thesis was to: (1) quantify changes in physical activity and physical function over the transition to retirement living; (2) examine the relationship between participant characteristics and physical activity in retirement living; and (3) describe the relationship between change in physical activity and change in physical and cognitive function. Older adults on the wait-lists for or living in retirement living were recruited. Physical activity was assessed with the Actigraph activity monitor and the CHAMPS activity questionnaire. Physical function was measured with the Senior Fitness Test. Cognitive function was assessed with a 45-minute test battery that assessed a variety of ...

Principal Investigator: Stephen E. Olvey, M.D.. Institution: Department of Neurological Surgery, University of Miami School of Medicine, 1501 N.W. 9th Avenue, Miami, FL 33136. The Development of a System Using Triaxial Accelerometers to Measure Head Motion and Energy Exposure During High Velocity Vehicular Impact. Update. Head injury is a serious safety concern in motorsports. In Indy car events from 1985 - 1989, 367 crashes occurred involving 413 drivers, 38 of these drivers sustained 48 injuries. Despite the use of helmets and other safety equipment, 29.2% of these injuries were closed head injuries. One of the most severe types of closed head injuries, diffuse axonal injury (DAI), occurs as a result of high velocity acceleration/ deceleration of the head with a rotational component that may cause widespread neuroanatomical and neurophysiological damage. Athletes in a variety of sports who survive this type of injury can be afflicted with persistent neurological deficits.. Triaxial ...

The objectives of this Study were to explore whether triaxial is more accurate than uniaxial accelerometry and whether shorter sampling periods (epochs) are more accurate than longer epochs. Physical activity data from uniaxial and triaxial (RT3) devices were collected in 1-s epochs from 31 preschool children (15 males, 16 females, 4.4 +/- 0.8 yrs) who were videoed while they engaged in 1-hr of free-play. Video data were coded using the Childrens Activity Rating Scale (CARS). A significant difference (p , .001) in the number of minutes classified as moderate to vigorous physical activity (MVPA) was found between the RT3 and the CARS (p , .002) using the cut point of relaxed walk. No significant difference was found between the GT1M and the CARS or between the RT3 and the CARS using the cut point for light jog. Shorter epochs resulted in significantly greater overestimation of MVPA, with the bias increasing from 0.7 mints at 15-s to 3.2 mins at 60-s epochs for the GT1M and 0 mins to 1.7 mins for ...

DAPA Measurement ToolkitDAPA Measurement Toolkit
The Global Physical Activity Questionnaire (GPAQ) was developed by the World Health Organization (WHO) for physical activity surveillance in countries. It collects information on physical activity participation in three settings (or domains) as well as sedentary behaviour, comprising 16 questions (P1-P16).. The GPAQ covers several components of physical activity, such as intensity, duration, and frequency, and it assesses three domains in which physical activity is performed (occupational physical activity, transport-related physical activity, and physical activity during discretionary or leisure time).. The GPAQ has been developed for face-to-face interviews conducted by trained interviewers. It has been tested in large scale population-based surveys with the general adult population.. It is advised that show cards be used when the GPAQ is administered. Show cards should be developed for each of the activity types covered by the GPAQ: vigorous and moderate activity at work, transport activity, ...

Circadian Polymorphisms in Night Owls, in Bipolars, and in Non-24-Hour Sleep CyclesCircadian Polymorphisms in Night Owls, in Bipolars, and in Non-24-Hour Sleep Cycles
In a representative population sample of San Diego adults 40-64 years of age, Ando et al. found that 10.9% reported trouble falling asleep at least 3 times/week, 16.9% reported trouble waking up in the morning at least 3 times/week, and 3.1% reported both.39 Though it is unlikely that such high percentages should be classified as having DSPS, there is as yet no validated basis for specifying the strength or validation of complaints that should be required for diagnosis. Ando et al. reported that average actigraphic bedtimes were 10 min. later than reported bedtimes, and actigraphic wake-up times were 22 min. later, with the participants awakening 45 min. later on weekend mornings.39 Sleeping late on weekend mornings may result from a variable combination of delayed sleep propensities, late-night social and recreational opportunities on weekends, and a build-up of sleep-debt during the work week. Clinical definitions have not yet evolved a practical methodology for accommodating the discrepancies ...
