Does a multimodal prehabilitation program improve sleep quality and duration in patients undergoing colorectal resection for cancer? Pilot randomized control trial.

Sleep difficulties are a common symptom in cancer patients at different stages of treatment trajectory and may lead to numerous negative consequences for which management is required. This pilot Randomized Controlled Trial (RCT) aims to assess the potential effectiveness of home-based prehabilitation intervention (prehab) on sleep quality and parameters compared to standard care (SOC) in colorectal cancer patients during the preoperative period and up to 8 weeks after the surgery. One hundred two participants (48.3% female, mean age 65 years) scheduled for elective resection of colorectal cancer were randomized to the prehab (n = 50) or the SOC (n = 52) groups. Recruitment and retention rates were 54% and 72%, respectively. Measures were completed at the baseline and preoperative, 4- and 8-week after-surgery follow-ups. Our mixed models' analyses revealed no significant differences between groups observed over time for all subjective and objective sleep parameters. A small positive change was observed in the perceived sleep quality only at the preoperative time point for the prehabilitation group compared to the SOC group, with an effect size d = 0.11 and a confidence interval (CI) between - 2.1 and - 0.1, p = .048. Prehab group patients with high anxiety showed a significant improvement in the rate of change of sleep duration over time compared to the SOC group, with a difference of 110 min between baseline and 8 weeks after surgery (d = 0.51, 95% CI: 92.3 to 127.7, p = .02). Multimodal prehabilitation intervention is feasible in colorectal cancer patients and may improve sleep duration for patients with high anxiety symptoms. Future large-scale RCTs are needed to confirm our results.

Evaluation of the "Build your bike!" pilot project by and for disadvantaged youth: A school-based intervention to promote active mobility / Évaluation du projet pilote « Construis ton vélo ! ¼ par et pour les jeunes en milieu défavorisé : une intervention en contexte scolaire pour promouvoir la mobilité active

The densification of urban centers has driven individuals with low income toward more affordable suburban neighborhoods, thereby constraining transportation options due to car-centric planning and the difficulty for public transit systems to meet mobility needs. Recognizing that active cycling promotes travel autonomy, social participation, and physical and mental well-being, the promotion of such behavior through localized interventions stands as a critical objective to foster transport equity. In this context, in collaboration with the organization "Cyclo Nord-Sud," this study aims to explore the outcomes and favorable components of the "Build Your Bike!" pilot project offered as an extracurricular activity to high school students in a disadvantaged neighborhood. A qualitative, comprehensive approach with an inductive and phenomenological perspective was employed. We conducted a focus group at the end of the program and used conceptual categories to complete the analysis. The results revealed positive outcomes from the program related to: 1) well-being, 2) learning, 3) access to a bicycle, and 4) mobility. Favorable mechanisms encompassed: 1) the approach of adult mentors, 2) extracurricular involvement, 3) teamwork, 4) manual labor, and 5) bicycle ownership upon program completion. The mechanisms identified by the participants hold potential for improvement in future program iterations and can guide the development of similar interventions.

La densification des centres urbains a poussé les personnes à faible revenu vers des quartiers suburbains plus abordables, limitant les options en transport en raison de l'aménagement centré sur la voiture et de la difficulté pour le réseau de transports en commun de répondre aux besoins de mobilité. Étant donné que les déplacements actifs à vélo favorisent l'autonomie des déplacements, la participation sociale et sont source de bienfaits pour la santé physique et mentale, leur promotion par des interventions à l'échelle locale est un objectif essentiel pour favoriser l'équité en matière de transport. C'est dans ce cadre que, en collaboration avec l'organisme Cyclo Nord-Sud, cette étude vise à explorer les retombées et les composantes favorables du projet pilote « Construis ton vélo ! ¼ offert en parascolaire à des élèves du secondaire en milieu défavorisé. Une méthode qualitative de type compréhensive avec une approche inductive et phénoménologique a été utilisée. Elle a été complétée par un entretien de groupe à la fin du programme et une analyse par catégories conceptualisantes. Les résultats ont révélé que les retombées positives du programme se rapportent : 1) au bien-être ; 2) aux apprentissages ; 3) à l'accès à un vélo ; et 4) à la motilité. Les fonctionnements favorables sont : 1) l'approche des adultes encadrants, 2) le parascolaire, 3) le travail d'équipe, 4) le travail manuel et 5) le fait de posséder un vélo à la fin du programme. Les mécanismes identifiés par les jeunes pourront être valorisés dans les prochaines versions du programme et guider la création d'interventions similaires.

Thinking Health-related Behaviors in a Climate Change Context: A Narrative Review.

BACKGROUND: Human activities have changed the environment so profoundly over the past two centuries that human-induced climate change is now posing serious health-related threats to current and future generations. Rapid action from all scientific fields, including behavioral medicine, is needed to contribute to both mitigation of, and adaption to, climate change. PURPOSE: This article aims to identify potential bi-directional associations between climate change impacts and health-related behaviors, as well as a set of key actions for the behavioral medicine community. METHODS: We synthesized the existing literature about (i) the impacts of rising temperatures, extreme weather events, air pollution, and rising sea level on individual behaviors (e.g., eating behaviors, physical activity, sleep, substance use, and preventive care) as well as the structural factors related to these behaviors (e.g., the food system); and (ii) the concurrent positive and negative roles that health-related behaviors can play in mitigation and adaptation to climate change. RESULTS: Based on this literature review, we propose a first conceptual model of climate change and health-related behavior feedback loops. Key actions are proposed, with particular consideration for health equity implications of future behavioral interventions. Actions to bridge the fields of behavioral medicine and climate sciences are also discussed. CONCLUSIONS: We contend that climate change is among the most urgent issues facing all scientists and should become a central priority for the behavioral medicine community.

Clustering of Health Behaviors in Canadians: A Multiple Behavior Analysis of Data from the Canadian Longitudinal Study on Aging.

BACKGROUND: Health behaviors such as physical inactivity, unhealthy eating, smoking tobacco, and alcohol use are each leading risk factors for non-communicable chronic disease. Better understanding which behaviors tend to co-occur (i.e., cluster together) and co-vary (i.e., are correlated) may provide novel opportunities to develop more comprehensive interventions to promote multiple health behavior change. However, whether co-occurrence or co-variation-based approaches are better suited for this task remains relatively unknown. PURPOSE: To compare the utility of co-occurrence vs. co-variation-based approaches for understanding the interconnectedness between multiple health-impacting behaviors. METHODS: Using baseline and follow-up data (N = 40,268) from the Canadian Longitudinal Study of Aging, we examined the co-occurrence and co-variation of health behaviors. We used cluster analysis to group individuals based on their behavioral tendencies across multiple behaviors and to examine how these clusters are associated with demographic characteristics and health indicators. We compared outputs from cluster analysis to behavioral correlations and compared regression analyses of clusters and individual behaviors predicting future health outcomes. RESULTS: Seven clusters were identified, with clusters differentiated by six of the seven health behaviors included in the analysis. Sociodemographic characteristics varied across several clusters. Correlations between behaviors were generally small. In regression analyses individual behaviors accounted for more variance in health outcomes than clusters. CONCLUSIONS: Co-occurrence-based approaches may be more suitable for identifying sub-groups for intervention targeting while co-variation approaches are more suitable for building an understanding of the relationships between health behaviors.

Health behaviors such as physical inactivity, unhealthy eating, smoking tobacco, and alcohol use are each leading risk factors for non-communicable chronic disease. A better understanding of which behavioral combinations people engage in, and which behaviors are associated with each other, may provide new insights to support the development of interventions to promote multiple health behavior change. Using data with two time points (N = 40,268) from the Canadian Longitudinal Study of Aging, we grouped people into clusters based on their health behaviors and examined how these clusters are associated with demographic characteristics and health indicators. Seven clusters were identified with sociodemographic patterns evident across several clusters. Correlations between behaviors were generally small. We compared whether individual health behaviors, or groupings of people based on their health behaviors, were better predictors of future health outcomes. Individual behaviors were slightly better predictors of future health outcomes than clusters.

Association Between Physical Activity, Sedentary Behaviors, and Sleep-Related Outcomes Among Cancer Survivors: a Cross-Sectional Study.

BACKGROUND: Limited research has examined the association between moderate to vigorous physical activity (MVPA), sedentary behavior (SB), and sleep-related outcomes in cancer survivors. Therefore, this study aimed to examine these associations using a nationally representative sample of US adults. METHODS: Data from the 2005-2018 National Health and Nutrition Examination Survey (NHANES) were analyzed. A total of 3229 adults with cancer histories were included. Physical activity was measured through accelerometry, and questions on daily activities, sedentary time, and sleep were collected during the household interview. Weighted multivariable analyses were conducted after accounting for the complex sampling design of the NHANES dataset. RESULTS: After adjustments, physical activity and SB outcomes were associated with several self-reported sleep-related parameters. Increases in minutes of self-reported MVPA and SB were associated with a decreased likelihood of reporting ≥ 8 h of sleep (OR = 0.92, 95% CI = 0.86, 0.99 and OR = 0.88, 95% CI = 0.82, 0.95). Converse associations were found between device-measured MVPA and SB with the likelihood of reporting often/always feeling overly sleepy during the day (OR = 0.86, 95% CI = 0.75 and OR = 1.13, 95% CI = 1.05, respectively). However, an increased likelihood of waking up too early in the morning (OR = 1.22, 95% CI = 1.04) was observed with increases in minutes of device-measured MVPA. CONCLUSIONS: A sensible strategy to decrease the frequency of sedentary breaks and increase minutes of physical activity throughout the day may reduce sleep complaints reported in cancer survivors.

"To Be Moving Is to Be Alive": A Walk-Along Study Describing Older Public Housing Tenants' Perceptions of Physical Activity.

Few studies have focused on older public housing tenants' perceptions of physical activity. Greater understanding of how they define, appreciate, and engage in physical activity could lead to better targeted promotion and reduced health inequalities for this subgroup of the population. We conducted 26 walk-along interviews with older public housing tenants in Montreal (Canada). Tenants were aged 60-93 years and lived in either one of three study sites including a commercial, a residential, and a mixed land-use area. Physical activity was described as a multidimensional construct through six interdependent dimensions: physiological, emotional, interpersonal, occupational, intellectual, and existential. Participants perceived physical activity as having potential for both well-being and ill-being. Perceptions of physical activity were a function of age, physical capacity, gender, culture, revenue, and relation to community. These results support using a life-course perspective and a broader definition in promoting physical activity to older public housing tenants.

Day-to-day associations between sleep and physical activity: a set of person-specific analyses in adults with overweight and obesity.

The objective of the present study was to estimate whether physical activity on one day was associated with both sleep quality and quantity the following night and to examine to what extent sleep on one night was associated with physical activity the next day. We collected data from 33 young adults who were overweight or obese and consistently wore a Fitbit Charge 3. A total of 7094 days and nights were analyzed. Person-specific models were conducted to test the bi-directional associations for each participant separately. Results suggest an absence of association between steps and sleep efficiency in the two directions. More heterogeneous results were observed for the association between steps and total sleep time, with 19 participants (58%) showing a negative association between total sleep time and next day steps, and 9 (27%) showing a negative association between steps and next day total sleep time. Taken together, these results suggest a potential conflicting association between total sleep time and physical activity for some participants.

Association between daily level of objective physical activity and C-Reactive protein in a representative national sample of adults with self-reported diagnosed arthritis or fibromyalgia.

PURPOSE: Examine the association between physical activity and sedentary time with high sensitivity C-Reactive protein levels in adults with arthritis and fibromyalgia. We also investigated the dose of physical activity that was associated with lower clinical levels of high sensitivity C-Reactive protein (< 3 mg/L). MATERIALS AND METHODS: Observational design was used to evaluate the variables of interest-based on the Canadian Health Measures Survey cycle 1-3 (2007-2012). Generalized adjusted additive models were used to explore the shape of the association between high sensitivity C-Reactive protein, daily physical activity, step count and sedentary time. High sensitivity C-Reactive protein was measured with blood samples. Physical activity, number of steps and sedentary time were objectively assessed using an Actical accelerometer. RESULTS: Daily moderate to vigorous physical activity and step count were significantly associated with lower high sensitivity C-Reactive protein levels, but daily light physical activity and sedentary time were not associated with high sensitivity C-Reactive protein levels, even after controlling for age, sex, daily smoking, body mass index, household income, level of education levels, marital status, work year and accelerometer wear time and season of accelerometer. Non-linear dose-response patterns were observed between daily moderate to vigorous physical activity as well as step count with high sensitivity C-Reactive protein levels. Lower high sensitivity C-Reactive protein levels were associated with 1-150 min of daily moderate to vigorous physical activity and with daily step count starting at 4000 in people with arthritis. Adults with fibromyalgia had lower levels of high sensitivity C-Reactive protein when engaging in 10-35 min of daily moderate to vigorous physical activity and in 5000-9000 daily steps. Optimal and specific doses of daily moderate to vigorous physical activity and steps were independently related to lower high sensitivity C-Reactive protein levels in adults with arthritis and fibromyalgia. CONCLUSIONS: Daily moderate to vigorous physical activity and step count were associated with high sensitivity C-Reactive protein levels that were below the clinical threshold. Given the positive outcomes of physical activity on health, adults with arthritis and fibromyalgia may benefit from these specific recommendations.

Predictors of Smoking Cessation and Relapse in Cancer Patients and Effect on Psychological Variables: an 18-Month Observational Study.

BACKGROUND: Although cancer patients are generally strongly advised to quit smoking in order to improve treatment efficacy and survival, up to 68 % of patients who were smokers at the time of cancer diagnosis continue smoking. Psychological factors such as depression and anxiety are likely to be associated with smoking behavior following a cancer diagnosis, but the empirical evidence is scarce. PURPOSE: This observational study aimed at estimating smoking cessation rates and assessing the effect of smoking cessation on psychological symptoms, as well as the predictive role of the same psychological variables on smoking cessation and smoking relapse following cancer surgery. METHODS: As part of a larger prospective, epidemiological study, smokers (n = 175) with a first diagnosis of nonmetastatic cancer completed the Hospital Anxiety and Depression Scale, the Insomnia Severity Index, and the Fear of Cancer Recurrence Inventory. Quitters (n = 55) and pair-matched nonquitters (n = 55) were compared on each symptom at pre-quitting, post-quitting, and at a 4-month follow-up. Predictors of smoking cessation and smoking relapse, including psychological variables, were also investigated. RESULTS: Fifty-five patients (31.4 %) stopped smoking at least on one occasion during the study. Of the 55 quitters, 27 (49.1 %) experienced a relapse. At pre-quitting, quitters had significantly higher levels of anxiety (p = .03) and fear of cancer recurrence (p = .01) than nonquitters, symptoms that significantly diminished at post-quitting and 4 months later in this subgroup of patients. Having breast cancer significantly predicted smoking cessation (relative risk [RR] = 3.08), while depressive symptoms were a significant predictor of smoking relapse (RR = 1.07). CONCLUSIONS: This study highlights the importance of psychological symptoms in predicting tobacco cessation and relapse among individuals with cancer. Our findings suggest that breast cancer patients are more inclined to stop smoking than patients with other cancers, but future studies should attempt to delineate the effect on smoking cessation of gender and other demographics that characterize this subgroup. This study also suggests that a particular attention should be paid to the early management of depressive symptoms in order to prevent smoking relapse.

Population-, intervention- and methodology-related characteristics of clinical trials impact exercise efficacy during adjuvant therapy for breast cancer: a meta-regression analysis.

OBJECTIVE: Significant heterogeneity was highlighted in recent meta-analyses examining exercise effects in cancer patients, suggesting that some characteristics may moderate exercise efficacy. The objectives of this meta-analysis are (1) to investigate the influence of methodology, population and intervention studies' characteristics on the association of exercise with fatigue, quality-of-life (QoL), anxiety and depression; (2) to identify exercise intervention characteristics that may maximize efficacy and evaluate the level of evidence about exercise efficacy in breast cancer patients receiving chemotherapy and/or radiotherapy. METHODS: Thirty-three randomized controlled trials (RCTs) evaluating exercise were systematically identified. Population, intervention and methodology characteristics were extracted, coded by two independent investigators and tested as moderators of exercise effect in meta-regression models. Psychological outcomes summary effects were then computed by pooling subgroup of RCTs based on categorized moderators. RESULTS: Indications of selection bias (random sequence generation) or attrition bias (high attrition rate, no intent-to-treat analysis) were associated with better exercise efficacy on QoL, anxiety and depression. Low total prescribed exercise doses (<140 METs.h) or short duration (<16 weeks) interventions yielded fatigue, anxiety and depression reductions whereas higher doses or duration did not. Mind-body interventions led to greater decrease of fatigue and anxiety rather than aerobic/resistance-based interventions. CONCLUSION: Our findings indicated that exercise-based interventions may improve fatigue, QoL, anxiety and depression, but the evidence mainly rely on studies prone to methodological biases. A prescription of approximately 100 MET.h, e.g. ~120 min of weekly moderate physical exercise for 10 weeks involving mind-body activities, could be advised to maximize fatigue reduction.

Self-reported physical activity in smoking pre-cessation is not a protective factor against relapse for all.

BACKGROUND: In recent years, the relationship between physical activity (PA) and smoking cessation has been increasingly studied. However, very few studies have investigated the possible protective role of PA on smoking relapse on the long term. OBJECTIVES: This study evaluated the impact of self-reported PA in precessation on smoking relapse. Other variables evaluated included measures of dependence, socio-demographic factors and smoking-related variables. Several possible interactions between PA and well identified factors influencing smoking relapse rate were also explored. METHODS: After the initial consultation, 345 smokers were consecutively recruited in a smoking-cessation unit. Smoking abstinence was collected regularly during consultation or by phone calls. PA was measured with the International Physical Activity Questionnaire short form. Cox proportional hazard model was performed to determine factors associated with smoking relapse. RESULTS: Among the initial sample, 227 adults were included in the survival analysis. After adjustment for potential cofounders, PA was not associated with smoking relapse. Self-efficacy level, absence of professional activity, previous attempts to quit and alcohol use disorders were associated with relapse. Secondary analysis showed a statistically significant effect of an interaction term for PA and antidepressant use on reducing smoking relapse (HR = .81, 95% CI: .66-.99). CONCLUSION AND SCIENTIFIC SIGNIFICANCE: Previous quit attempts and professional activity were positive predictors of smoking abstinence, with alcohol use disorder a negative predictor. PA was not found to be a significant predictor of smoking relapse, with only a positive interaction term seen for persons on antidepressant treatment.

Exercise and Counseling for Smoking Cessation in Smokers With Depressive Symptoms: A Randomized Controlled Pilot Trial.

OBJECTIVE: Despite various strategies to help smokers with depressive disorders to quit, the smoking relapse rate remains high. The purpose of this pilot study was to estimate the effects of adding an exercise and counseling intervention to standard smoking cessation treatment for smokers with depressive disorders. We hypothesized that the exercise and counseling intervention would lead to improved abstinence, reduced depressive symptoms, and increased physical activity. METHODS: Seventy smokers with current depressive disorders were randomly assigned to standard smoking cessation treatment plus exercise and counseling (n = 35) or standard treatment plus a time-to-contact control intervention on health education (n = 35). Both programs involved 10 sessions over 8 weeks. The primary outcome was continuous abstinence since the quit date and was measured at week 8 (end of the intervention) and again at 12-, 24-, and 52-week follow-ups. RESULTS: Nearly 60% of participants were female (n = 41), 38 (52.3%) were single, 37 (52.9%) had education beyond high school, and 32 (45.7%) met criteria for major depressive disorder or dysthymia. Participants in the two treatment conditions differed at baseline only in marital status (χ(2) = 4.28, df = 1, p =.04); and smoking abstinence self-efficacy, t(66) = -2.04, p =.04). The dropout rate did not differ significantly between groups and participants attended 82% and 75% of the intervention and control sessions, respectively. Intention-to-treat analysis showed that, at 12 weeks after the beginning of the intervention, continuous abstinence did not vary significantly between the intervention and control groups: 48.5% versus 28.5%, respectively, ORadj = 0.40, 95% CI [0.12-1.29], p =.12. There were no group differences in depressive symptoms, but the intervention group did outperform the control group on the 6-minute walking test (Mint = 624.84, SD = 8.17, vs. Mcon = 594.13, SD = 8.96, p =.015) and perceived physical control (Mint = 2.84, SD = 0.16, vs. Mcon = 2.27, SD = 0.18, p =.028). The sample was not large enough to ensure adequate statistical power. CONCLUSIONS: This finding, while preliminary, suggests that an exercise and counseling intervention may yield better results than health education in improving smoking abstinence. This study is registered at www.clinincaltrials.gov under # NCT01401569.

Smoking behavior characteristics of non-selected smokers with childhood attention-deficit/hyperactivity disorder (AD/HD) history: a systematic review and meta-analysis.

It is unclear whether adult smokers with childhood attention-deficit/hyperactivity disorder history (CH) have more severe smoking behavior than non-CH smokers, while it is clearly suggested that CH adolescents have more severe smoking behavior than CH adolescents. The aim of the present comprehensive meta-analysis is to determine whether CH smokers have more severe smoking behavior characteristics than those without and the effect of age on the association between CH and smoking behavior. We included all case-control studies and first round data collection of observational studies addressing the difference in smoking behavior characteristics of CH smokers versus non-CH smokers, with validated scales or structured interviews, without any language or date restriction. Nine studies (including 365 smokers with CH and 1,708 smokers without) were included. Compared to non-CH smokers, CH smokers smoked significantly more cigarettes [standardized mean differences (SMD) = 0.15, 95 % CI 0.01-0.28, p = 0.04] and began to regularly smoke earlier (SMD = -0.28, 95 % CI -0.49; -0.07, p = 0.01) but were not significantly more nicotine dependent (SMD = 0.23, 95 % CI -0.04 to 0.48, p = 0.08). After removing the single adolescent study, the significant association between CH and number of daily smoked cigarettes disappeared, and subgroups analyses confirmed that the significant association between CH and number of daily smoked cigarettes disappeared as age increased. Our meta-analysis illustrates a clinically important link between CH and tobacco smoking in adolescence but not later in life. Further high-quality studies are needed to confirm this finding, as only two studies included participants with a mean age below 20 years.

Validation of the TTM processes of change measure for physical activity in an adult French sample.

BACKGROUND: Processes of change (POC) are constructs from the transtheoretical model that propose to examine how people engage in a behavior. However, there is no consensus about a leading model explaining POC and there is no validated French POC scale in physical activity PURPOSE: This study aimed to compare the different existing models to validate a French POC scale. METHOD: Three studies, with 748 subjects included, were carried out to translate the items and evaluate their clarity (study 1, n = 77), to assess the factorial validity (n = 200) and invariance/equivalence (study 2, n = 471), and to analyze the concurrent validity by stage × process analyses (study 3, n = 671). RESULTS: Two models displayed adequate fit to the data; however, based on the Akaike information criterion, the fully correlated five-factor model appeared as the most appropriate to measure POC in physical activity. The invariance/equivalence was also confirmed across genders and student status. Four of the five existing factors discriminated pre-action and post-action stages. CONCLUSION: These data support the validation of the POC questionnaire in physical activity among a French sample. More research is needed to explore the longitudinal properties of this scale.

[The effectiveness and lessons learned from UK exercise referral systems]. / Les systèmes d'orientation à l'activité physique au Royaume-Uni?: efficacité et enseignements.

INTRODUCTION: UK Exercise Referral Systems (ERS) have been developed to encourage physical activity in the general population. This systematic review investigated the effectiveness and cost-effectiveness of ERS. Identification of factors influencing ERS uptake, adherence and success were also investigated. METHODS: Studies were identified from Medline, Cochrane and Pascal and bibliographies of relevant papers. Interventions providing access to ERS (randomized controlled trials or controlled trials), experimental or qualitative studies, and meta-analyses were included. RESULTS: Twenty six studies met the inclusion criteria. Compared with usual care, ERS showed an increased number of participants who achieved 90-150 minutes of physical activity of at least moderate intensity per week. However, no significant difference in long-term outcomes (e.g., quality of life, body mass index, glycated haemoglobin, anxiety) were identified between ERS and comparator groups. Cost-effectiveness analysis suggested that ERS were more cost-effective for participants with co-morbid medical conditions. A higher adherence rate was associated with better effectiveness of ERS. DISCUSSION: Limited evidence supports the efficacy of ERS to increase physical activity or improve health outcomes. This evidence-based analysis could support the development of effective ERS in France.

A systematic review of ambient heat and sleep in a warming climate.

Climate change is elevating nighttime and daytime temperatures worldwide, affecting a broad continuum of behavioral and health outcomes. Disturbed sleep is a plausible pathway linking rising ambient temperatures with several observed adverse human responses shown to increase during hot weather. This systematic review aims to provide a comprehensive overview of the literature investigating the relationship between ambient temperature and valid sleep outcomes measured in real-world settings, globally. We show that higher outdoor or indoor temperatures are generally associated with degraded sleep quality and quantity worldwide. The negative effect of heat persists across sleep measures, and is stronger during the hottest months and days, in vulnerable populations, and the warmest regions. Although we identify opportunities to strengthen the state of the science, limited evidence of fast sleep adaptation to heat suggests rising temperatures induced by climate change and urbanization pose a planetary threat to human sleep, and therefore health, performance, and wellbeing.

Physical Literacy in the Context of Climate Change: Is There a Need for Further Refinement of the Concept?

The concept of physical literacy (PL) has witnessed enormous popularity in recent years and has undergone substantial theoretical evolvement during the last 2 decades. However, the research field pertaining to PL has not yet initiated discussions around the challenges of climate change and the alignment with conceptualizations of planetary health. Therefore, we argue that the consideration of an "ecological domain" for individual physical activity, in the form of ecological awareness, would further evolve the concept. We illustrate how to potentially integrate adjustments within the most frequent PL definitions of the field (eg, those in Australia, Canada, England, Ireland, the United States, or by the International Physical Literacy Association) without questioning the entire integrity of these elaborate conceptualizations. An ecological domain of PL would not only interact with the postulated physical, cognitive, psychological/affective, and social domains of PL but also have important implications for the (re)design of interventions and practices in physical activity contexts. We call the scientific community, both on national and international scales, to intensify the discussions and initiate a research agenda involving an "ecological domain" of PL.

Acceptability and Feasibility of the Telehealth Bariatric Behavioral Intervention to Increase Physical Activity Before Bariatric Surgery: A Single-Case Experimental Study (Part I).

BACKGROUND: Physical activity (PA) can play an important role in optimizing metabolic/bariatric surgery (MBS) outcomes. However, many MBS patients have difficulty increasing PA, necessitating the development of theory-driven counseling interventions. This study aimed to (1) assess the feasibility and acceptability of the TELEhealth BARIatric behavioral intervention (TELE-BariACTIV) trial protocol/methods and intervention, which was designed to increase moderate-to-vigorous intensity physical activity (MVPA) in adults awaiting MBS and (2) estimate the effect of the intervention on MVPA. METHODS: This trial used a repeated single-case experimental design. Twelve insufficiently active adults awaiting MBS received 6 weekly 45-min PA videoconferencing counseling sessions. Feasibility and acceptability data (i.e., refusal, recruitment, retention, attendance, and attrition rates) were tracked and collected via online surveys, and interviews. MVPA was assessed via accelerometry pre-, during, and post-intervention. RESULTS: Among the 24 patients referred to the research team; five declined to participate (refusal rate = 20.8%) and seven were ineligible or unreachable. The recruitment rate was 1.2 participants per month between 2021-09 and 2022-07. One participant withdrew during the baseline phase, and one after the intervention (retention rate = 83.3%). No participant dropouts occurred during the intervention and 98.6% of sessions were completed. Participants' anticipated and retrospective acceptability of the intervention was 3.2/4 (IQR, 0.5) and 3.0/4 (IQR, 0.2), respectively. There was a statistically significant increase in MVPA [Tau-U = 0.32(0.11; 0.51)] from pre- to post-intervention. CONCLUSION: Despite a low recruitment rate, which could be explained by circumstances (COVID-19 pandemic), results support feasibility, acceptability, and preliminary efficacy of the TELE-Bari-ACTIV intervention for increasing MVPA in patients awaiting MBS.

Smoking cessation, depression, and exercise: empirical evidence, clinical needs, and mechanisms.

INTRODUCTION: Smoking is significantly more common among persons with major depressive disorders (MDDs). Furthermore, smokers with MDD report more difficulties when they quit smoking (greater withdrawal symptoms, higher probability of relapse). The aim of this narrative review is to describe research on exercise and depression and exercise and smoking cessation. METHODS: We have critically reviewed various smoking cessation intervention programs for depressive smokers examining (a) the protective effect of exercise against relapse for smokers with MDD and (b) the benefits of exercise for treating withdrawal symptoms. We have also reviewed the current literature investigating the mechanisms between exercise-depression and exercise-smoking. RESULTS: This review suggests that exercise may reduce depressive symptoms following cessation and provide a useful strategy for managing withdrawal symptoms in smokers with MDD. Various psychological, biological, and genetic hypotheses have been tested (e.g., distraction hypothesis, expectations hypothesis, cortisol hypothesis) and few have obtained significant results. CONCLUSIONS: It might be beneficial for health professionals to recommend physical activity and promote supervised exercise sessions for smokers with MDD during smoking cessation. Future research needs to examine relationships between exercise, smoking, and depression with transdisciplinary and ecological momentary assessment.

Counseling and exercise intervention for smoking reduction in patients with schizophrenia: a feasibility study.

Smoking cessation is possible for individuals with schizophrenia but the relapse rate is high. It is necessary to develop more flexible approaches to help these patients. The aim of this study was to examine the feasibility of an intervention approach that integrates counseling and exercise for participants with schizophrenia or schizoaffective disorder. A single group prospective design was used in this study. A sample of inpatients with schizophrenia or schizoaffective disorder participated in a program called "oxygen group", a program combining five sessions of smoking reduction counseling and three sessions of moderate intensity exercise over an 8-week period. Tobacco consumption, motivation, carbon monoxide level, anxiety and depression, smoking self-efficacy, nicotine dependence and waist circumference were measured pre- and post-intervention. Participants reported their satisfaction with the study characteristics after completion of the intervention. Smoking consumption and CO level were assessed at 6-week post-intervention follow-up. Twelve individuals (mean age 45.7±10.8years) were recruited. Participant attendance was 81.3%. There were no dropouts. Significant decreases were found for tobacco consumption (P=.04) and CO rate (P=.003) at the end of the intervention and were maintained at 6-week follow-up. Compared to baseline levels, there were no changes in depression and anxiety. Smoking cessation motivation increased significantly. This intervention appears feasible and acceptable to patients with schizophrenia and there were promising findings regarding smoking reduction. Larger trials to test the intervention are warranted.
