Effects of Digital Physical Activity Interventions for Breast Cancer Patients and Survivors: A Systematic Review and Meta-Analysis.

The benefits of physical activity (PA) for breast cancer (BC) patients and survivors are well documented. With the widespread use of the internet and mobile phones, along with the recent coronavirus disease 2019 pandemic, there has been a growing interest in digital health interventions. This study conducted a systematic review and meta-analysis to evaluate the effects of digital PA interventions for BC patients and survivors in improving PA and quality of life (QoL). We searched eight databases, including PubMed, CINAHL, Embase, Scopus, Web of Science, Cochrane Central Register of Controlled Trials in the Cochrane Library, RISS, and DBpia. Studies were included if they provided digital PA interventions, assessed PA and QoL among BC patients and survivors, and were published from inception to December 31, 2022. In total, 18 studies were identified. The meta-analysis showed significant improvement in the total PA duration (five studies; standardized mean difference [SMD] = 0.71; 95% confidence interval [CI], 0.25-1.18; I2 = 86.64%), functional capacity (three studies; SMD = 0.38; 95% CI, 0.10-0.66; I2 = 14.36%), and QoL (nine studies; SMD = 0.45; 95% CI, 0.22-0.69; I2 = 65.55%). Digital PA interventions for BC patients and survivors may significantly improve PA, functional capacity, and QoL. Future research should focus on the long-term effects of digital PA interventions, using objective outcome measures.

Research on the Transitional Care Model-based Health Management Protocol for Patients after Sleeve Gastrectomy

Background: Postoperative care after sleeve gastrectomy is critical to a successful outcome because of the increasing popularity of the procedure in the treatment of obesity and related conditions. Objectives: The purpose of this study was to evaluate the effectiveness of a health intervention plan for sleeve gastrectomy patients based on the Transitional Care Model (TCM). Methods: This study was conducted from January 2021 to January 2022 at Mudanjiang Hospital. The study included a total of 72 patients who underwent sleeve gastric volume reduction. Patients were randomly divided into an intervention group (36 cases) and a control group (36 cases). The intervention group received care based on a health intervention plan, while the control group received routine care. Various assessments were performed on the first day of hospitalization and three months after surgery, such as questionnaires on general information, physical activity, eating behavior, quality of life, and adherence to implementation. Results: After the intervention, the intervention group showed significant improvements in total duration of physical activity, moderate-intensity activity, restrained eating, emotional eating, physical pain, mental health, and social functioning (p<0.05). However, there were no significant differences between groups in activity intensity, walking, external diet, physical functioning, physical role, general health, or vitality (p>0.05). Adherence to the health management protocol was significantly higher in the intervention group (p<0.05). Conclusion: The health intervention plan based on the transitional care model improves physical activity, eating behaviors, quality of life, and compliance in sleeve gastrectomy patients.

Objective. Development of guidelines of healthy physical activity volume for school-age children of the quarantine measures Materials and methods. Results of a survey of physical activity (PA) and mental health of children and adolescents of school age (n=1354) were included in the study. Anthropometrical-physiological parameters and the level of well-being were determined in 39 children of primary school age. The optimal duration and frequency of various PA for different age and gender groups was determined by constructing linear regression models. Statistical analysis was carried out using STATISTICA 8.0. Results and discussion. Increased physical activity significantly reduces depression (r=– 0,25; p<0,001) and anxiety levels (r=– 0,14; p<0,001). Also the relationship between the duration of MVPA and anxiety indicators (r=–0.10; p<0.001) and depression indicators (r=–0,22; p<0,001) was determined. The recommended duration of the total PA (PAt, more than 2 hours a day) was observed during the quarantine by 42.5±2.4% of students of the younger age group, 36.6±2.3% of students of the middle age group and 33.3±2.3% high school students. It is determined that the chances having the middle and high levels of well-being are 8 times higher in the group of children who have PAt more 2 hours/day during the quarantine (OR = 8,0; CІ 1,54-41,63) and are 8,2 times higher - who have MVPA more 60 minute/day (OR = 8,17; CІ 1,41-47,22). The indicator of the total duration of physical activity was normalized according to the maximum value of the indicator for each age group and gender to check the developed standards. Conclusions. It is determined that the daily duration PAt for school-age children during the quarantine measures for the purpose of prevention depression disorders should be more 2 hours/day for primary school children and 2.2 hours/day for adolescents. The favorable for mental health minimal duration of MVPA, which is typical of most sports, for primary school children is amount 60 minutes/day for boys and 40 minutes/day for girls, for adolescents is 60 minutes/day for boys and 45 minutes/day for girls. The daily duration of MVPA for preventing of depressive disorders of primary school children is about 40 minutes/day for girls and about 60 minutes/day for boys. For preventing of anxiety disorders of primary school children is about 40 minutes/day for girls and about 50 minutes/day for boys, respectively. A single health-enhancing duration of sporting activity is 1,2-1,5 hours for primary school children and 1,5-2,0 hours for adolescents.

Identification of physical activity and sedentary behaviour dimensions that predict mortality risk in older adults: Development of a machine learning model in the Whitehall II accelerometer sub-study and external validation in the CoLaus study.

Identification of new physical activity (PA) and sedentary behaviour (SB) features relevant for health at older age is important to diversify PA targets in guidelines, as older adults rarely adhere to current recommendations focusing on total duration. We aimed to identify accelerometer-derived dimensions of movement behaviours that predict mortality risk in older populations. We used data on 21 accelerometer-derived features of daily movement behaviours in 3991 participants of the UK-based Whitehall II accelerometer sub-study (25.8% women, 60-83 years, follow-up: 2012-2013 to 2021, mean=8.3 years). A machine-learning procedure was used to identify core PA and SB features predicting mortality risk and derive a composite score. We estimated the added predictive value of the score compared to traditional sociodemographic, behavioural, and health-related risk factors. External validation in the Switzerland-based CoLaus study (N=1329, 56.7% women, 60-86 years, follow-up: 2014-2017 to 2021, mean=3.8 years) was conducted. In total, 11 features related to overall activity level, intensity distribution, bouts duration, frequency, and total duration of PA and SB, were identified as predictors of mortality in older adults and included in a composite score. Both in the derivation and validation cohorts, the score was associated with mortality (hazard ratio=1.10 (95% confidence interval=1.05-1.15) and 1.18 (1.10-1.26), respectively) and improved the predictive value of a model including traditional risk factors (increase in C-index=0.007 (0.002-0.014) and 0.029 (0.002-0.055), respectively). The identified accelerometer-derived PA and SB features, beyond the currently recommended total duration, might be useful for screening of older adults at higher mortality risk and for diversifying PA and SB targets in older populations whose adherence to current guidelines is low.

Breaking up sitting with short frequent or long infrequent physical activity breaks does not lead to compensatory changes in appetite, appetite-regulating hormones or energy intake

The aim of this study was to determine the appetite-related responses to breaking up prolonged sitting with physical activity bouts differing in frequency and duration among adult females. Fourteen sedentary females aged 34 ± 13 years with a body mass index of 27.1 ± 6.3 kg/m2 (mean ± SD) took part in a randomised crossover trial with three, 7.5 h conditions: (1) uninterrupted sitting (SIT), (2) sitting with short frequent 2-min moderate-intensity walking breaks every 30 min (SHORT-BREAKS), and (3) sitting with longer duration, less frequent 10-min moderate-intensity walking breaks every 170–180 min (LONG-BREAKS). The intensity and total duration of physical activity was matched between the SHORT-BREAKS and LONG-BREAKS conditions. Linear mixed models were used to compare the outcomes between conditions with significance being accepted as p ≤ 0.05. There were no significant between-condition differences in hunger, satisfaction, prospective food consumption or overall appetite area under the curve (AUC) (all p ≥ 0.801). Absolute ad libitum energy intake and relative energy intake (REI) did not differ significantly between conditions (all p ≥ 0.420). Acylated ghrelin and total peptide YY incremental and total AUC did not differ significantly between conditions (all p ≥ 0.388). Yet, there was a medium effect size for the higher acylated ghrelin incremental AUC in SHORT-BREAKS versus SIT (d = 0.61); the reverse was seen for total AUC, which was lower in SHORT-BREAKS versus SIT (d = 0.69). These findings suggest that breaking up sitting does not lead to compensatory changes in appetite, appetite hormones or energy intake regardless of physical activity bout duration and frequency among adult females.

Association between physical health and physical activity behaviors for children aged 3-6 years in kindergarten: A cross-sectional study from China.

To explore the association between the physical health (PH) and physical activity behavior (PAB) of children aged 3 to 6 years, and to provide a basis for the scientific planning of children's physical activity behavior in kindergarten. A total of 18041 children in China aged 3 to 6 years were selected as the research subject. The PH monitoring indicators were measured according to "The National Physical Fitness Measurement Standards Manual" (Preschool Children Version) (NPFMSM), and PAB was reported by teachers. The chi-square test was used to test for differences in PH and PAB across groups, the percentile method was used to rank PAB, correlation analysis was used to analyze the association between components of PH and PAB, and multiple linear regression was used to determine the independent association between PAB and PH. Participants in this study exhibited poor PH status, and the detection rates of failure were 16.4% for boys and 16.8% for girls, and showed a decreasing trend with increasing age. The grade difference and sex difference in PH components were statistically significant (P<0.01). PAB changes to static activities with increasing age, mainly to static indoor physical activities (SIPAs). The regression effects of the total duration of physical activity (TDPA) and dynamic physical activity (DPA) on PH score and physical fitness (PF) score were significant (P < 0.01) but not statistically significant with static physical activity (SPA) (P>0.05). Dynamic outdoor physical activity (DOPA) is the core factor affecting children's PH, and is significantly positively correlated with the components of PH. PAB in kindergarten can improve children's PH, and reasonable planning of PAB in kindergarten has a targeted effect on PH promotion.

Moderate-to-vigorous physical activity duration is more important than timing for physical function in older adults

The positive association between the total duration of physical activity and performances of physical function may vary at different times of the day as circadian rhythm regulates individuals in response to external stimulations. We aimed to examine the association of timing-specific and overall moderate-to-vigorous physical activity (MVPA) with performances of physical function in older adults. A cross-sectional analysis was conducted among 118 older adults (mean age = 70.0 ± 5.0 years). We assessed and identified timing-specific (morning: 06:01–12:00; afternoon: 12:01–18:00; evening: 18:01–24:00) and overall MVPA using a triaxial accelerometer. Different measures of physical function were evaluated including handgrip strength (by grip dynamometer), gait speed (5-m walk test), basic functional mobility (timed up and go test), and lower limb strength (five times sit-to-stand test). Multivariate linear regression models adjusting for covariates were used to investigate the associations. Participants spent 25.0 (± 26.2) minutes in MVPA per day on average, half the time spent during the morning (47.7%), followed by during the afternoon (29.9%) and evening (21.6%). The time spent on overall MVPA was generally associated with better physical function performances. There was statistical evidence for the percentages of MVPA engagement during the morning [B = 0.214, 95% confidence interval (CI) 0.001 to 0.428] and afternoon (B = − 0.273, 95% CI − 0.518 to − 0.027) associated with basic functional mobility but with contrary directions; the percentage of MVPA engagement during the evening was associated with less time spent in gait speed performance (B = − 0.237, 95% CI − 0.468 to − 0.006). Our findings inform implications that the overall MVPA engagement was more important than timing-specific MVPA to older adults’ physical function performances. Strategies for accumulating time of MVPA is more practical and effective than encouraging to engage MVPA in specific timing for the enhancement of functional ability and therefore prevent disability among older adults.

The Relationship between Dog Ownership and Physical Activity in Korean Adults.

BackgroundMany studies have reported that dog ownership is effective in encouraging physical activity. However, the association between living with a dog and enhanced physical activity has not been clearly verified. Thus, this study aimed to investigate the effects of dog ownership on the amount of physical activity in a representative sample of Korean adults.MethodsThis cross-sectional study administered the International Physical Activity Questionnaire (IPAQ) to 1,299 individuals who visited the international healthcare center of one hospital in Seoul, Korea, between August and December in 2018. Based on responses to the IPAQ survey, the amount and duration of physical activity was calculated to analyze relationships with dog ownership.ResultsThe total amount (P=0.02) and duration of physical activity (P=0.02) and the duration of vigorous-intensity physical activity (P=0.04) were significantly higher among dog owners than non-dog owners. The duration of daily physical activity increased with dog ownership by 18.6 minutes (P=0.01). A comparison of dog owners according to whether they walked with their dogs revealed that dog walking had no significant effect on the amount and duration of physical activity, inactivity, or health-enhancing physical activity status. There was a sex-specific association between dog ownership and total duration of physical activity in females.ConclusionThe duration of physical activity increased by dog ownership. However, the higher levels of physical activity among dog owners may not necessarily be explained by dog ownership or walking with dogs. This outcome suggests that raising a dog can help promote physical activity.

Does having a pet influence the physical activity of their young female owners?

BackgroundMany studies have shown that having a dog has an impact on the increase in physical activity (PA) of people. However, what is often not taken into account in many such studies is owning of other pets. The aim of this study was to compare PA levels between animal owners and non-owners and to research potential differences between owners of different kinds of animals.Method111 young females of mean age 21 ± 1.2 years enrolled in this cross-sectional study. Czech version of short International physical activity questionnaire (IPAQ) was used to assess PA level, supplemented with a question about whether they owned an animal and what kind.ResultsPeople who owned a pet had higher frequency and duration of moderate physical activity (MPA) and spent more MET/min/wk. (p < 0.05). This difference has projected into total PA duration and also into calories burned in a week. Furthermore, a statistically significant difference between subgroups of animal owners was also confirmed for MPA and total PA in favour of horse owners.ConclusionsAnimal owners generally reported higher PA levels compared to people who do not own any pets. However, similarly significant in this particular age group was the kind of animal these young women owned.

Effects of Physical Activity on Neurophysiological and Gene Expression Profiles in Chronic Back Pain: Study Protocol.

Despite the emphasis on exercise to reduce pain and improve function among people with chronic low back pain (cLBP), little is known about the underlying mechanism of the impact of exercise on the neurophysiological and gene transcription alterations that characterize cLBP. To present a study protocol to examine the feasibility, acceptability, and initial efficacy of Problem-Solving Pain to Enhance Living Well (PROPEL) with the support of nurse consultations and wearable activity-tracking technology on self-management (SM) knowledge, skills, physical activity, and pain and to examine the differential neurophysiological and gene expression profiles in cLBP participants from pre- to post-PROPEL. A pretest and posttest study is employed on 40 adults ages 18-60 years with cLBP who do not have serious complications and/or comorbidities that affect sensorimotor function. Participants will receive video modules focused on SM and biweekly phone consultations to facilitate symptom monitoring and problem-solving while increasing physical activity frequency and duration. Participants will be assessed for outcomes including SM skills, physical activity, and pain every 2 weeks for 12 weeks. We will examine the participants' differential neurophysiological and gene expression profiles at 12 weeks postintervention and correlate these outcomes with the total duration of physical activity. The study began in September 2018. Of the 99 subjects that were screened, 23 were enrolled and 8 completed data collection. Comparing the neurophysiological and gene expression profiles of people with cLBP exposed to PROPEL could inform the development of interventions that offer personalized physical activity dosage along with general SM support. Web-based programs such as PROPEL have the potential to enhance accessibility of evidence-based interventions that improve functionality and quality of life among people living with cLBP.

Assessment of physical activity intensity and duration in the paediatric population: evidence to support an a priori hypothesis and sample size in the agreement between subjective and objective methods.

We aimed to provide evidence for an a priori hypothesis and sample size for subjectively assessing physical activity intensity and duration in paediatric population, adopting objective methods as the reference. We searched electronic databases, reference lists and author databases. Correlation coefficients were pooled as an indicator of agreement estimates. We found 183 agreement analyses (94.5% based on correlation coefficients) from 89 studies that met our inclusion criteria. We identified four physical activity parameters addressing intensity and two parameters addressing duration. The physical activity parameters focusing on intensity were measured only by questionnaires, and the best correlation was achieved by moderate-to-vigorous physical activity compared with a heart rate monitor. In addition, total physical activity duration had a stronger correlation with an accelerometer when measured by diaries or logs than when measured by questionnaires. In both cases, the correlation was moderate. Studies with sample sizes between 50 and 99 subjects showed measurements that were stable in both magnitude and interpretation. Our findings suggest that the agreement between subjective and objective methods for assessing physical activity intensity and duration is weak to moderate. Furthermore, sample sizes ranging from 50 to 99 subjects provide stable agreement estimates between methods.

Sleep and physical activity: a cross-sectional objective profile of people with rheumatoid arthritis.

Regular physical activity (PA) is important for people with rheumatoid arthritis (RA). Poor sleep is a common complaint among people with RA, which may have an influence on their PA levels. There is a lack of objective information regarding total sleep time (TST) and PA duration in this population. A cross-sectional study design was used. SenseWear Pro3 Armband(R)TM is used to measure TST and total PA duration. Four valid days, with 95% wear time necessary for inclusion in final results. Disease activity and function were measured using the DAS-28, HAQ and VAS. Data analysis carried out using SPSS v22. Seventy-five (75) participants completed monitoring period, with 51 (68%) meeting modified PA duration guidelines. Data with 95% wear time over a minimum of 4days were available for 32 recorded participants, with a mean TST of 5.7 (SD_1.11) hours per night and a median 1.25 (IQR_1.88) hours of daily PA. TST had a positive significant relationship with PA (p = 0.018); PA demonstrated a negative significant relationship with functional limitations (p = 0.009) and correlated with lower CRP levels; CRP levels had in turn a significant relationship to global health (p = 0.034). Total sleep time was low for people with RA. People with RA who are more physically active have longer TST. These findings provide an objective profile of TST and PA duration in people with RA and suggest a relationship between increased PA duration and longer TST. Further research is needed to confirm these novel findings.

Moderate-intensity physical activity, hippocampal volume, and memory in older adults with mild cognitive impairment

Background Greater physical activity (PA) is associated with better memory performance and greater hippocampal volume in older adults. However, most studies to date assessed PA via questionnaires and thereby lacked objective characterization of PA (eg, intensity, duration, etc.). Thus, we currently do not have a comprehensive understanding of PA characteristics that are important for neuroprotection, especially among older adults with mild cognitive impairment (MCI). Thus, using triaxial accelerometers, we examined the association between light- and moderate-intensity PA, total duration of PA, hippocampal volume, and memory in older adults with MCI. Methods This cross-sectional study involved 310 older adults with MCI who completed neuropsychological tests of memory, and structural magnetic resonance imaging. Participants were instructed to wear the accelerometer on an elastic band on their hip at all times for 2 weeks. Average daily duration of light, moderate, and total PA (min/day) was calculated. Results Moderate PA was associated with hippocampal volume (β = .167, p = .003) after controlling for age, but light PA (β = -.021, p = .713) and total PA (β = .011, p = .844) were not. Both light and moderate PAs were not associated with memory performance. Structural equation modeling demonstrated that moderate PA was not directly associated with memory but significantly contributed to hippocampal volume; hippocampal volume loss was significantly and directly associated with poor memory performance. Conclusions Our results suggest that the benefits of moderate PA on memory among older adults with MCI are mediated by hippocampal volume. Furthermore, light PA may not reduce dementia risk among older adults with MCI.

Effect of dronabinol therapy on physical activity in anorexia nervosa: a randomised, controlled trial.

The level of physical activity is inappropriately high in up to 80% of the patients suffering of anorexia nervosa (AN), as a result of conscious efforts to lose weight, affect regulation and biological adaptive changes to starvation induced by hypothermia and neuroendocrine mechanisms. The purposes of this paper were to (1) assess the effect of dronabinol-a synthetic cannabinoid agonist-on physical activity in patients with chronic and stable AN, and to (2) unravel the role of leptin and cortisol in this process. This prospective, randomised, double-blind, crossover study was conducted at a specialised care centre for eating disorders. Twenty-four adult women with AN of at least 5-year duration received either the dronabinol-placebo or placebo-dronabinol sequence. Physical activity was monitored during the fourth week of each intervention. Body weight, leptin and urinary free cortisol excretion were measured repeatedly during the trial. Changes in behavioural dimensions related to AN were assessed by Eating Disorder Inventory-2. The total duration of physical activity did not change, while its average intensity increased by 20% (P = 0.01) during dronabinol therapy, resulting in an increased energy expenditure with 68.2 kcal/day (P = 0.01) above placebo. This randomised, double-blind study revealed that cannabinoid agonist treatment was associated with a modest increase in physical activity in adult women with severe and longstanding AN. Additionally, we detected a strong relationship between the circulating levels of leptin and physical activity in these chronically undernourished patients.
