The coupled dynamics of information-behavior-epidemic propagation considering the heterogeneity of adoption thresholds and network structures in multiplex networks

During epidemics, individual responses to prevention and control information vary significantly, affecting the execution of preventive measures. This paper introduces a novel model to analyze the co-evolution of the information-behavior-epidemic dynamic, accounting for the heterogeneity in individual behavioral adoption thresholds and network structures. The model consists of three layers: the upper layer, utilizing scale-free social networks to represent the diffusion of information; the middle and lower layers, employing community networks, to illustrate individuals’ decision-making and epidemic transmission processes, respectively. We applied the Heaviside step function to depict the effects of information and local environmental factors on individuals’ decisions. Through the microscopic Markov chain approach (MMCA), we determined the epidemic threshold. Our methodology also included extensive Monte Carlo (MC) simulations to validate our theoretical predictions. Our results reveal several key insights: (i) reducing community mobility and the threshold for adopting preventive behaviors can significantly restrain the scale of the epidemic and delay outbreaks; (ii) the level of individual activity in the physical contact network has a significant influence on epidemic transmission; (iii) integrating individuals’ behavior adoption thresholds induces a two-stage phase change, deviating from the continuous phase transition typically observed in epidemic transmission.

Individual activity levels and presence of conspecifics affect fish passage rates over an in‐flume barrier

AbstractDams and other in‐stream obstacles disrupt longitudinal connectivity and hinder fish from moving between habitats. Fishways and other fish passage solutions are used to pass fish over these artificial migration barriers. Fish passage functionality, however, varies greatly with fish passage design and environmental conditions and depends on fish species and characteristics. In particular, swimming performance and fish behaviour are considered key characteristics to predict fish passage performance. It is also well known, but not well quantified, that the presence of conspecifics affects fish passage behaviour. In this study, we quantified individual passage rates of PIT‐tagged gudgeons (Gobio gobio) over a scaled deep side notch weir in an hydraulic flume. We then quantified individual swimming capability (time to fatigue) and activity level (distance moved in an open field test) for the same individual fish and tested for potential effects on fish passage rate. To check for potential group effects, we then repeated the passage experiment for fish individually or in groups of five. More active fish displayed higher passage rates compared to less active fish, and fish passed the obstacle at higher rates in groups of five compared to alone. No effect of fish swimming capability on passage rates was detected. This result highlights the need to take both individual variation as well as the presence and behaviour of conspecifics into account in fish passage studies and evaluations. Doing so has the potential to improve the understanding of fish behaviour, and in the end, the design of fish passage solutions. Future studies should explore these results on free ranging fish and in relation to in‐situ fish passage solutions.

Physical Activity Levels of Individuals Employed in the Sports Directorate

The aim of this study is to examine the physical activity levels of civil servants employed in a sports-related state institution, with a focus on individual factors and their attitudes toward physical exercise. The research cohort comprised 160 individuals, randomly selected from employees working in the sports directorate, consisting of 79 women and 81 men. Data collection was conducted through an online questionnaire encompassing a personal information form and the International Physical Activity Questionnaire-Short Form. Descriptive statistics and Chi-square analyses were employed for data analysis, supplemented by calculations of Cohen's d effect sizes to assess the relationship between variables. Results from the analysis revealed that 19.40% of sports directorate employees were categorized as inactive, 20.60% as minimally active, and 60.0% as sufficiently active. Furthermore, significant disparities in physical activity levels were observed concerning gender, age, marital status, and sports history (p

Impacts of active mobility on individual health mediated by physical activities

Active mobility, encompassing walking and cycling for transportation, is a potential solution to health issues arising from inadequate physical activity in modern society. However, the extent of active mobility's impact on individual physical activity levels, and its association with health as mediated by physical activities, is not fully quantified. This study aims to clarify the direct relationship between active mobility usage and individual health, as well as the indirect relationship mediated by physical activity, with a focus on varying levels of physical activity intensity. Utilizing data from the 2017 U.S. National Household Travel Survey (NHTS), we employed Poisson regression to predict active mobility usage based on socio-demographic and household socio-economic characteristics. A Structural Equation Model (SEM) was then used to investigate the direct and indirect effects of active mobility on individual health, mediated by physical activity. We further segmented individuals according to their intensity of physical activity to examine how such effect differs between different levels of physical activity. The study demonstrates that active mobility usage positively correlates with both the amount and intensity of physical activity. The effect of active mobility on individual health includes a direct positive effect (29% for intensity, 67.7% for amount) and an indirect effect mediated by physical activity (71% for intensity, 32.3% for amount). Notably, the mediation effect of active mobility on health is more substantial in the context of vigorous physical activities compared to light or moderate activities. Our findings reveal a significant positive influence of active mobility on individual health, encompassing both direct and indirect effects mediated by physical activities. These results quantitatively underscore the health benefits of active mobility and suggest the importance of promoting active mobility as a strategy to improve public health.

Investigation of the Effect of Ramadan Fasting on Sleep Patterns, Nutritional Characteristics, and Physical Activity Levels in Young Individuals Doing Active Sports

Fasting during Ramadan causes significant changes in important features of human life, such as sleep behaviors, nutrition, and physical activity. This study aimed to investigate the effects of Ramadan fasting on sleep patterns, nutritional characteristics, and physical activity levels in young individuals doing active sports. Twenty-six individuals (14 males-12 females) between the ages of 19-25 and doing active sports participated in the study voluntarily. In the study, the athletes' sleep patterns, nutrition, and physical activity characteristics were determined using a questionnaire. Participants answered a questionnaire about their sleep patterns, nutritional characteristics, and physical activity levels one week before and during the first week of Ramadan. Comparisons between before and Ramadan answers were made by paired t-tests. Wilcoxon’s z was calculated for comparisons between the non-parametric variables. According to the statistical comparisons, the number of workouts per week, and daily training time, were significantly (p<0.05) decreased during Ramadan. In addition, it has been determined that the sleeping and waking hours have changed. It is seen that there is no statistically significant difference in total sleep times. There was no significant difference was found in the high-intensity, moderate-intensity physical activity and sitting times of the athletes (p>0.05). Significant decreases were found in walking and total calorie (MET) parameters (p<0.001). Moreover, no significant difference was found in the total calorie, carbohydrate, fat, protein, and liquid consumption. Ramadan fasting was affected by the number of workouts per week, daily training number, bedtime, waking-up time, walking, and total calorie (MET) parameters.

Effect of pain on activity and participation in individuals with unilateral lower-extremity amputation based on the International Classification of Functioning, Disability, and Health.

Amputation is a major life-changing event and is regarded as one of the loading causes of permanent disability. However, amputation often causes changes in painful and nonpainful sensory experiences. Pain after amputation has been shown to increase functional limitations caused by limb loss and lower quality of life. This study aimed to examine the effect of pain on activity and participation in individuals with unilateral below-knee amputations according to the International Classification of Functioning, Disability, and Health. Cross-sectional study. In the study, 64 individuals were divided into 2 groups: those who experienced pain and those who did not. Group 1 included 33 below-knee amputees who experienced pain (27 males, mean age 43.9 ± 12.6 years) and Group 2 included 31 below-knee amputees who did not experience pain (25 males, mean age 47.4 ± 12.1 years). The McGill Pain Questionnaire and visual analog scale were used to assess pain, the Prosthetic Limb Users Survey of Mobility was used to assess activity, and the Reintegration to Normal Living Index was used to assess participation. Demographic characteristics of the 2 groups were statistically insignificant (P > 0.05). The nonpainful group had significantly higher activity and participation scores than the painful group (P < 0.001). It was found that phantom pain and stump pain in below-knee amputees limited activity and participation. It was also shown that phantom pain has a more negative effect on the activity level of individuals than stump pain.

Assessment of Physical Activity During Pandemic Periods: Development of the Questionnaire, Determination of Primary Validity, and Psychometric Properties.

This study aimed to develop the "Pandemic Period Physical Activity Scale (PPPAS)" to determine the physical activity level of healthy individuals during the pandemic period. Research data were collected from the "Socio-Demographic Questionnaire Form,""International Physical Activity Short Form,""Tampa Scale for Kinesiophobia,""Coronavirus Anxiety Scale,""Epidemic Anxiety Scale,""Expert Evaluation Form," and "Pandemic Period Physical Activity Scale," exploratory factor analysis revealed that the scale consisted of 3 sub-dimensions and 31 items. Confirmatory factor analysis suggested that the fit indices χ2/Df: 2.343; root mean square error of approximation: 0.048; incremental fit index: 0.955; comparative fit index: 0.954; goodness of fit index: 0.912; normed fit index: 0.923; non-normed fit index: 0.950; adjusted goodness of fit index: 0.896; root mean square residuals: 0.060; standardized root mean square residual: 0.047. The total Cronbach Alpha coefficient of the scale was found to be 0.912 while the intraclass correlation coefficient of the scale was calculated as 0.958 (p<0.001). As a result of the analyses conducted, it was concluded that the PPPAS is a valid and reliable measurement.

No Panic in Pandemic: The Impact of Individual Choice on Public Health Policy

Problem definition: Public health interventions, such as social distancing and lockdown, play an important role in containing infectious disease outbreaks, such as coronavirus disease 2019 (COVID-19). Yet, these interventions could cause significant financial losses because of the disruption to regular socioeconomic activities. Moreover, an individual’s activity level is influenced not only by public health policies but also by one’s perception of the disease burden of infection. Strategic planning is required to optimize the timing and intensity of these public health interventions by considering individual responses. Methodology/results: We use the multinomial logit choice model to characterize individual reactions to the risk of infection and public health interventions and integrate it into a repeated Stackelberg game with the susceptible-infected-recovered disease transmission dynamics. We find that the individual equilibrium activity level is higher than the socially optimal activity level because of an individual’s ignorance of the negative externality imposed on others. As a result, implementing lockdown and social distancing policies at moderate disease prevalence may be equivalently critical, if not more, compared with their implementations when the disease prevalence is at its peak level. To verify these findings, we conduct numerical studies based on representative COVID-19 data in Minnesota. Managerial implications: Our results call for policymakers’ attention to consider the impact of individuals’ responses in the planning for different pandemic containment measures. Individuals’ responses in the pandemic may significantly affect the optimal implementation of lockdown and social distancing policies.

The interaction of information diffusion and epidemic transmission in time-varying multiplex networks with simplicial complexes and asymmetric activity levels

Information diffusion among individuals occurs in various ways, mainly involving pairwise and higher-order interactions, and their coexistence can be characterized by simplicial complexes. This paper introduces a novel two-layer model that investigates coupled information-epidemic propagation. Specifically, the upper layer represents the virtual layer that depicts information diffusion, where the interaction process among individuals is not only limited to pairwise interactions but also influenced by higher-order interactions. The lower layer denotes the physical contact layer to portray epidemic transmission, where the interaction process among individuals is only considered in pairwise interactions. In particular, the emergence of asymmetric activity levels in two-layer networks reshapes the propagation mechanism. We then employ the micro-Marko chain approach (MMCA) to establish the probabilistic transfer equation for each state, deduce the epidemic outbreak threshold, and investigate the equilibrium and stability of the proposed model. Furthermore, we perform extensive Monte Carlo (MC) simulations to validate the theoretical predictions. The results demonstrate that the higher-order interaction generates synergistic reinforcement mechanisms that both facilitate information diffusion and inhibit epidemic transmission. Moreover, this study suggests that the activity level of individuals at the physical contact level has a greater impact on epidemic transmission. In addition, we utilize two different networks to explore the influence of network structural features on the transmission and scale of epidemics.

MHealth-Based Just-in-Time Adaptive Intervention to Improve the Physical Activity Levels of Individuals With Spinal Cord Injury: Protocol for a Randomized Controlled Trial.

The lack of regular physical activity (PA) in individuals with spinal cord injury (SCI) in the United States is an ongoing health crisis. Regular PA and exercise-based interventions have been linked with improved outcomes and healthier lifestyles among those with SCI. Providing people with an accurate estimate of their everyday PA level can promote PA. Furthermore, PA tracking can be combined with mobile health technology such as smartphones and smartwatches to provide a just-in-time adaptive intervention (JITAI) for individuals with SCI as they go about everyday life. A JITAI can prompt an individual to set a PA goal or provide feedback about their PA levels. The primary aim of this study is to investigate whether minutes of moderate-intensity PA among individuals with SCI can be increased by integrating a JITAI with a web-based PA intervention (WI) program. The WI program is a 14-week web-based PA program widely recommended for individuals with disabilities. A secondary aim is to investigate the benefit of a JITAI on proximal PA, defined as minutes of moderate-intensity PA within 120 minutes of a PA feedback prompt. Individuals with SCI (N=196) will be randomized to a WI arm or a WI+JITAI arm. Within the WI+JITAI arm, a microrandomized trial will be used to randomize participants several times a day to different tailored feedback and PA recommendations. Participants will take part in the 24-week study from their home environment in the community. The study has three phases: (1) baseline, (2) WI program with or without JITAI, and (3) PA sustainability. Participants will provide survey-based information at the initial meeting and at the end of weeks 2, 8, 16, and 24. Participants will be asked to wear a smartwatch every day for ≥12 hours for the duration of the study. Recruitment and enrollment began in May 2023. Data analysis is expected to be completed within 6 months of finishing participant data collection. The JITAI has the potential to achieve long-term PA performance by delivering tailored, just-in-time feedback based on the person's actual PA behavior rather than a generic PA recommendation. New insights from this study may guide intervention designers to develop engaging PA interventions for individuals with disability.

Relationship between Physical Activity Level and Sleep Quality in Mothers of Individuals with Special Needs

Purpose: The study aimed to investigate the relationship between physical activity level and sleep quality in mothers of individuals with special needs.&#x0D; Material and Methods: Three hundred twenty-one mothers (average age: 41.92±9.53 years) with a disabled child participated in the study from Osmangazi county of Bursa province in Türkiye. Demographic characteristics of the mothers were collected through a personal information form prepared by the researchers. The mothers’ physical activity level was determined using the International Physical Activity Questionnaire-short form (IPAQ-SF). The mothers’ sleep quality was determined using the Pittsburgh Sleep Quality Index (PSQI). The physical activity level of the disabled individuals was determined based on their mothers’ statements. &#x0D; Results: The mean IPAQ-SF score of the mothers was found to be 1080.58±986.88 MET-min/week, and their mean PSQI score was determined to be 7.46±3.62. The disabled individuals’ physical activity level was evaluated as a)15.9% (n=51) of the disabled individuals regularly participated in a sporting activity, b) 32.4% (n=104) did not participate in sports but made efforts to stay active, and c) 51.7% (n=166) were considered inactive. Pearson correlation analysis revealed that a) there was no relationship between IPAQ-SF and PSQI scores (r: -0.056, p=0.313), b) the physical activity level of individuals with special needs did not correlate with PSQI scores of the mothers (r: -0.95, p=0.089), and c) no relationship was determined between the age of individuals with special needs and mothers' sleep quality and physical activity level.&#x0D; Conclusion: It can be concluded that increasing the physical activity level of mothers cannot be an effective intervention to improve sleep quality in mothers of individuals with special needs. Further research is needed to explore the relationship between physical activity level and sleep quality in mothers of individuals with special needs.

Impact of Perch Provision Timing on Activity and Musculoskeletal Health of Laying Hens.

Laying hens can experience a progressive increase in bone fragility due to the ongoing mobilization of calcium from bones for eggshell formation. Over time, this escalates their susceptibility to bone fracture, which can reduce their mobility and cause pain. The provision of perches as an exercise opportunity could potentially enhance bone strength, but the timing of exposure to perches during the birds' development may modulate its impact. The objective of this study was to investigate the enduring impacts of perch provision timing on the musculoskeletal health of laying hens. A total of 812 pullets were kept in different housing conditions (seven pens/treatment, 29 birds/pen) with either continuous access to multi-tier perches from 0 to 40 weeks of age (CP), no access to perches (NP), early access to perches during the rearing phase from 0 to 17 weeks of age (EP), or solely during the laying phase from 17 to 40 weeks of age (LP). At weeks 24, 36, and 40 of age (n = 84 birds/week), three birds per pen were monitored for individual activity level, and blood samples were collected from a separate set of three birds per pen to analyze serum levels of tartrate-resistant acid phosphatase 5b (TRACP-5b) and C-terminal telopeptide of type I collagen (CTX-I) as markers of bone demineralization. At 40 weeks of age, three birds per pen (n = 84) were euthanized for computed tomography scans to obtain tibial bone mineral density (BMD) and cross-sectional area (CSA) with further analysis including muscle deposition, tibial breaking strength, and tibial ash percent. During week 24, hens from CP, EP, and LP pens had the highest overall activity compared to hens from NP pens (p < 0.05) with no differences between treatments for overall activity level during weeks 36 or 40 (p > 0.05). During weeks 24, 36, and 40, hens from CP and LP pens showed greater vertical and less horizontal activity compared to hens from EP and NP pens (p < 0.05). TRACP-5b and CTX-I concentrations did not differ between treatments at week 24 of age (p > 0.05). Hens from CP pens had the lowest TRACP-5b and CTX-I concentrations at 36 weeks of age with EP and LP hens showing intermediate responses and NP hens having the highest concentration (p < 0.05). At 40 weeks of age, CP hens had the lowest TRACP-5b and CTX-I concentrations compared to NP hens (p < 0.05). Total bone CSA did not differ between treatments (p > 0.05), but CP had greater total BMD than NP (p < 0.05) with no differences between EP and LP treatments. CP and LP hens had larger biceps brachii, pectoralis major, and leg muscle groups as well as greater tibial breaking strengths than EP and NP treatments (p < 0.05). CP hens had higher tibial ash percentages compared to EP, LP, and NP (p < 0.05). Our results indicate that providing continuous perch access improves the musculoskeletal health and activity of laying hens at 40 weeks of age compared to no access and that late access to perches has a beneficial impact on activity, muscle deposition, and bone strength.

Where did my dog go? A pilot study exploring the movement ecology of farm dogs.

Movement ecology is important for advancing our comprehension of animal behavior, but its application is yet to be applied to farm dogs. This pilot study uses combined GPS and accelerometer technology to explore the spatial patterns and activity levels of free roaming farm dogs, Canis familiaris (n = 3). Space-use distributions and range sizes were determined to compare locations visited across days and between individuals, as well as in relation to specific areas of interest. Individual activity levels were analyzed and compared within and between dogs. Space-use patterns and range sizes showed variation among the dogs, although substantial similarity in overall spatial distributions were observed between each pair. Among the dogs, the extent of spatial distribution overlap between days varied, with some individuals exhibiting more overlap than others. The dogs allocated different amounts of their time close to landscape features, and to slow-, medium-, and fast movements. This study demonstrates the potential of using automated tracking technology to monitor space-use and interactions between dogs, livestock, and wildlife. By understanding and managing the free ranging behavior of their farm dogs, farmers could potentially take steps to improve the health and wellbeing of both their dogs and their livestock, limiting disease spread, and reducing the possibility of related economic losses.

Video-Based Physical Exercise Effects on Young Adults in Social Isolation During the Coronavirus Pandemic

Aim: The aim of this study is to evaluate the effectiveness of video-based exercises on the physical activity levels of individuals between the ages of 18-40 in social isolation to prevent the spread of the COVID-19 pandemic. Method: 64 volunteers participated as the control and 64 study groups were divided randomly and equally into two groups, the video-based exercise group (VEG) and the control group (CG). The video-based exercise group was included in an exercise program for 20 minutes, 7 days a week for 6 weeks. The primary outcome measure was the International Physical Activity Questionnaire (Short Form) (IPAQ-SF). Secondary outcome measures were the Nottingham Health Profile (NHP), Pittsburgh Sleep Quality Index (PSQI), Beck Anxiety Inventory (BAI), Distress Tolerance Scale (DTS), sit and reach test, shoulder flexibility test, squat test, plank test, lateral bridge test (LBT), crunch test and single leg stance test (SLST). Tests were applied to the groups at the beginning and the end of the study. Results: There was a statistically significant difference in all parameters in the study group before and after the application (p&amp;lt;0.05). According to the intergroup comparisons, there was a statistically significant increase between the groups in IPAQ-SF, Sit and Reach Test, Push Up Test, Plank Test, LBT, and SLST Tests; there was a statistically significant decrease between the groups in DTS, BAI, PSQI, and NHP scores (except for pain and social isolation scores) (p&amp;lt;0.05). Conclusion: Our findings will shed light on the management of the physiotherapy and rehabilitation process by contributing to the increasing evidence in the literature on the effectiveness of video-based exercises and improving health-related multifaceted parameters in various post-pandemic situations where access to health services and preventive rehabilitation is restricted.

Pre- and Post-Operative Pain Intensity and Physical Activity Levels in Individuals with Acetabular Dysplasia Undergoing Periacetabular Osteotomy: A Prospective Cohort Study.

Acetabular dysplasia (AD) causes pain, limited function, and development of early hip osteoarthritis. Periacetabular osteotomy (PAO) is a surgical treatment for AD that aims to reposition the acetabulum to reduce pain and improve function. To examine pain recovery and physical activity (PA) before and during the six months after PAO. Case series, prospective. Individuals with AD scheduled for PAO were enrolled. Pain intensity was evaluated before PAO and at one week and one, three, and six months following PAO. PA levels was evaluated before and six months following PAO using accelerometers (time spent in sedentary behavior, light PA, moderate-to-vigorous PA [MVPA], and daily steps) and the International Physical Activity Questionnaire (IPAQ; time spent in walking and in MVPA). Pain improvements was examined over time following PAO using a repeated-measures one-way ANOVA as well as improvements in PA levels before and six months after PAO using paired-sample t tests. In addition, time spent in MVPA was qualitatively summarized at each time point (before and six months after PAO) measured by both the accelerometers and IPAQ. Out of 49 screened participants, 28 were enrolled, and 23 individuals (22 females; age=23.1±7.9 years) completed both study visits. Compared to pre-PAO pain, participants reported significant improvements in pain at one month and onward following PAO (p\<0.011). However, PA levels at six months following PAO did not differ from pre-PAO PA levels (p>0.05). Qualitatively, participants reported spending more time in MVPA recorded by the IPAQ (pre-PAO=73.3±150.2 mins/day; six-months after PAO=121.2±192.2 mins/day), compared with MVPA recorded by accelerometers (pre-PAO=22.6±25.2 mins/day; six-months after PAO=25.0±21.4 mins/day). Individuals with AD reported significant pain reduction at one month and up to six months after PAO, but PA levels did not change six months after PAO compared to baseline testing. Future studies should consider examining longitudinal pain recovery and PA improvements over longer periods of time with larger samples of individuals with AD undergoing PAO and identifying modifiable factors to minimize pain and increase PA participation.

The relationship between quick return shift schedules and burnout among nurses: A prospective repeated measures multi-source study

BackgroundIn today's world, essential health care services are expected round the clock, leading to distinct shift work requirements. A notable aspect is the “quick return,” where the rest interval between nursing shifts is <11 h. Preliminary research suggests a potential association between quick return schedules, diminished sleep quality, and possible nurse burnout. Yet, the motivation of nurses could potentially moderate this relationship. ObjectiveTo examine a moderated-mediation model, whereby sleep duration and nurse's motivation act together to mediate the link between quick return schedules and nurse's burnout. DesignA prospective repeated measures (4–5 nursing shifts per nurse) multi-source (self-report and objective measures) study. SettingInternal and surgical departments across one large and one medium scale teaching hospitals in Israel. ParticipantsRegistered nurses who provide direct patient care (n = 79) across 369 shifts. MethodsNurses completed a questionnaire containing personal information and information regarding their shifts during the study week. They wore an accelerometer (a wrist worn device that monitors and records an individual's activity level) during a work-week to objectively determine their sleep duration, completed a motivation questionnaire at the beginning of each shift, and completed a burnout questionnaire at the end of the week. Mixed-model regression analysis was used to test a moderated-mediation model following Hayes' recommendations, whereby the joint effect of sleep duration and motivation mediates the link between quick return schedules and burnout. ResultsThe moderated-mediation model was supported. Quick return schedules were negatively statistically significantly associated with sleep duration (b = −126.54, SE = 20.85, p < 0.001); so that more frequent quick return schedules were related to shorter sleep duration. However, no direct correlation was observed between sleep duration and burnout (p = 0.171). A statistically significant interaction was observed between sleep duration and motivation (b = 0.00, SE = 0.00, p < 0.001) concerning burnout. Thus, nurses with lower motivation were prone to experiencing higher levels of burnout with shorter sleep duration compared to nurses with higher motivation. ConclusionsThe mediating role of sleep duration, moderated by motivation, plays a role in the connection between quick return schedules and burnout. This indicates that nurses can sustain their work motivation even within the demands of quick return schedules, consequently mitigating burnout levels. To prioritize employees' well-being, organizations should adopt shift work structures that minimize quick return schedules and extend nurses' sleep duration. Consequently, managers must employ strategies to enhance nurses' motivation when addressing scenarios that necessitate quick return schedules.

Directional associations among real-time activity, sleep, mood, and daytime symptoms in major depressive disorder using actigraphy and ecological momentary assessment

Previous research has suggested that individuals with major depressive disorder (MDD) experienced alterations in sleep and activity levels. However, the temporal associations among sleep, activity levels, mood, and daytime symptoms in MDD have not been fully investigated. The present study aimed to fill this gap by utilizing real-time data collected across time points and days. 75 individuals with MDD and 75 age- and gender-matched healthy controls were recruited. Ecological momentary assessments (EMA) were adopted to assess real-time mood status for 7 days, and actigraphy was employed to measure day-to-day sleep-activity patterns. Multilevel modeling analyses were performed. Results revealed a bidirectional association between mood/daytime symptoms and activity levels across EMA intervals. Increased activity levels were predictive of higher alert cognition and positive mood, while an increase in positive mood also predicted more increase in activity levels in depressed individuals. A bidirectional association between sleep and daytime symptoms was also found. Alert cognition was found to be predictive of better sleep in the subsequent night. Contrariwise, higher sleep efficiency predicted improved alert cognition and sleepiness/fatigue the next day. A unidirectional association between sleep and activity levels suggested that higher daytime activity levels predicted a larger increase in sleep efficiency among depressed individuals. This study indicated how mood, activity levels, and sleep were temporally and intricately linked to each other in depressed individuals using actigraphy and EMA. It could pave the way for novel and efficacious treatments for depression that target not just mood but sleep and activity levels.
