Patients and methods: We conducted a secondary analysis of semi-structured interviews carried out as part of a multicentered collective qualitative case study. In total, 24 patients, aged 2–76 years with a confirmed diagnosis of asthma (or were parents of a child), who renewed the prescription for inhaled corticosteroids in the past year, participated in this study. The thematic analysis focused on asthma-related events and experiences reported by the patients. Consistent with narrative inquiry, similar patterns were grouped together, and three vignettes representing the different realities experienced by the patients were created. Results: The comparison of experiences and events reported by the patients suggested that patients’ perceptions and beliefs regarding asthma and treatment goals influenced their self-management-related behaviors. More specifically, the medical context in which the patients were followed (ie, frame in which the medical encounter takes place, medical recommendations provided) contributed to shape their understanding of the disease and the associated treatment goals. In turn, a patient’s perception of the disease and the treatment goals influenced asthma self-management behaviors related to environmental control, lifestyle habits, and medication intake. Conclusion: Current medical recommendations regarding asthma self-management highlight the importance of the physicians’ guidance through the provision of a detailed written action plan and asthma education. These data suggest that while physicians contribute to shaping patients’ beliefs and perceptions about the disease and treatment goals, patients tend to listen to their own experience and manage the disease accordingly. Thus, a medical encounter between the patient and the physician, aiming at enhancing a meaningful conversation about the disease, may lead the patient to approach the disease in a more effective manner, which goes beyond taking preventative paths to avoid symptoms.

Kim L Lavoie,1–3 Gregory Moullec,1,2,4 Catherine Lemiere,2 Lucie Blais,2 Manon Labrecque,2 Marie-France Beauchesne,2 Veronique Pepin,2,4 André Cartier,2 Simon L Bacon1,2,41Montreal Behavioural Medicine Centre, 2Research Centre, Hôpital du Sacré-Cœur de Montréal – A University of Montreal Affiliated Hospital, Montréal, 3Department of Psychology, University of Quebec at Montreal (UQAM), Succursale Center-Ville, Montreal, 4Department of Exercise Science, Concordia University, Montreal, Quebec, CanadaPurpose: Daily adherence to inhaled corticosteroid (ICS) regimens is one of the most important factors linked to achieving optimal asthma control. Motivational interviewing (MI) is a client-centered communication style that focuses on enhancing intrinsic motivation to engage in appropriate self-management behaviors. MI has been shown to improve a variety of health behaviors including medication adherence in other disorders, but its efficacy for the improvement of ICS adherence in asthmatics has yet to be examined. This pilot “proof of concept” trial assessed the feasibility of MI to improve daily ICS adherence and asthma control levels in adult asthmatics.Methods: Fifty-four poorly controlled (Asthma Control Questionnaire [ACQ] score ≥1.5), highly nonadherent (filled

The purpose of this study was to evaluate the influence of trait and state rumination on cardiovascular recovery following a negative emotional stressor. Cardiovascular data was collected from 64 undergraduate women during a 10-min baseline period, 5-min emotional recall stress task, and a 15-min recovery period. Trait rumination was assessed using the Stress Reactive Rumination Scale and state rumination was assessed 5 and 10 min after the stressor, using a thought-report technique. Results indicated that trait and state rumination interacted such that low trait ruminators who were ruminating at 10 min after the termination of the stressor had poorer diastolic blood pressure and high-frequency heart rate variability recovery compared to low trait ruminators who were not ruminating. State rumination was not associated with cardiovascular recovery in high trait ruminators. Results suggest that rumination may play a role in the association between stress and hypertension by prolonging cardiovascular activation following stress. [ABSTRACT FROM AUTHOR]

An unhealthy lifestyle, including excess caloric intake, lack of exercise, smoking, and excessive alcohol consumption, increases one's risk of developing cardiovascular disease (CVD). However, the exact mechanisms by which these behaviors influence the development and progression of CVD have yet to be determined. Endothelial function (EF) has been shown to be a potent predictor of CVD, yet the effects of health behaviors on EF are not clear. The literature assessing the role of four health behaviors, obesity (a proxy of excess caloric intake), smoking, physical inactivity, and alcohol consumption, on the development of endothelial dysfunction is reviewed. Potential mechanisms through which these behaviors may influence EF are discussed. Smoking, being overweight or obese, and physical inactivity are all associated with decreased EF. A direct causal relationship between these measures and EF is suggested by the fact that improvements in these behaviors leads to parallel improvements in EF. The influence of alcohol consumption is somewhat more contentious, with some studies indicating a dose-response relationship such that those with greater consumption have poor EF. However, other studies have shown that those who drink moderately have the best EF. Although there is a growing body of literature implicating poor health behaviors in the development of endothelial dysfunction, more work is needed to establish the exact mechanisms by which this occurs. To our knowledge, there are no studies that have assessed the impact of multiple health behaviors or the interaction of health behaviors on EF. [ABSTRACT FROM AUTHOR]

BACKGROUND: The high burden of asthma appears to be related to poor asthma control. Although previous studies have reported associations between depressive disorders (DDs) and anxiety disorders (ADs) and worse asthma control and quality of life, the relative impact of these disorders on asthma control and quality of life has not been explored. This study evaluated the relative impact of having a DD and/or AD on asthma control and quality of life. METHOD: Five hundred four consecutive adults with confirmed, physician-diagnosed asthma underwent a brief, structured psychiatric interview using the Primary Care Evaluation of Mental Disorders. Asthma control and asthma-related quality of life were assessed using the Asthma Control Questionnaire (ACQ) and the Asthma Quality of Life Questionnaire (AQLQ). All patients underwent standard spirometry. RESULTS: Thirty-one percent of patients (n = 157) met the diagnostic criteria for one or more psychiatric disorders (8% had DD only, 12% had AD only, and 11% had both). Analyses revealed independent effects for DDs on total ACQ scores (p < 0.01), and for DDs and ADs on total AQLQ scores and all four AQLQ subscales (p < 0.05). There were no interaction effects. CONCLUSIONS: Results suggest that DDs and ADs are associated with worse asthma-related quality of life, but only DDs are associated with worse asthma control. Interestingly, having both a DD and an AD did not confer additional risk for worse asthma control or quality of life. Physicians may want to consider the differential impact of negative mood states when assessing levels of asthma control and quality of life. [ABSTRACT FROM AUTHOR]

This study explored the association between pandemic-related loss/reduction of employment, sex, COVID-19-related stress and relational conflicts. A sample of 5103 Canadians from the iCARE study were recruited through an online polling firm between October 29, 2020, and March 23, 2021. Logistic regressions revealed that participants with loss/reduction of employment were 3.6 times more likely to report increased relational conflicts compared to those with stable employment (OR = 3.60; 95% CIs = 3.03-4.26). There was a significant interaction between employment status and sex ( x 2  = 10.16; p  < 0.005), where loss/reduction of employment was associated with more relational conflicts in males compared to females. There was a main effect of COVID-19-related stress levels on relational conflicts (increased stress vs no stress : OR = 9.54; 95% CIs = 6.70-13.60), but no interaction with loss/reduction of employment ( x 2  = 0.46, p  = 0.50)., Competing Interests: Declaration of conflicting interestsThe authors declared the following potential conflicts of interest with respect to the research, authorship and/or publication of this article: Dr. Lavoie is a member of the Canadian COVID-19 Expert Advisory Panel (Health Canada).

Objective: While behavior change counseling (BCC) targeting health risk behaviors has shown efficacy for improving patient health outcomes, barriers to knowledge translation have resulted in poor uptake among health care providers (HCPs). This article outlines the development of a new BCC training framework for HCPs, from inception to readiness for efficacy testing. It provides an example of integrated knowledge translation (iKT) used in alignment with the obesity-related behavioral intervention trials model., Method: (a) A modified Delphi process identified essential BCC skills for HCPs; (b) a survey assessed HCP attitudes and training needs; (c) an online competency assessment tool was developed using iKT mixed methods; (d) a training program was developed and refined using a logic model; and (e) the program was optimized using iterative rounds of participant feedback. A future proof-of-concept trial (f) will determine the program's readiness for full efficacy testing., Results: A Delphi panel ( n = 46) identified 11 core BCC competencies for HCPs, defining "motivational communication." The HCP survey ( n = 80) showed willingness to devote 4 hr to introductory training in BCC. The Motivational Communication Competency Assessment Test (MC-CAT: an online, interactive evaluation tool) and a motivational communication training program (MOTIVATOR: accredited for continuing education by the Royal College of Physicians and Surgeons of Canada) were collaboratively developed with knowledge users. The optimization process ( n = 11) provided key feedback, with minor changes being made to the program., Conclusions: In developing a new BCC framework, obstacles to BCC implementation were addressed through an iterative iKT process. This should improve eventual intervention uptake. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Nutrition-focused interventions are essential to optimize the bariatric care process and improve health and weight outcomes over time. Clear and detailed reporting of these interventions in research reports is crucial for understanding and applying the findings effectively in clinical practice and research replication. Given the importance of reporting transparency in research, this study aimed to use the Template for Intervention Description and Replication (TIDieR) checklist to evaluate the completeness of intervention reporting in nutritional weight management interventions adjunct to metabolic and bariatric surgery (MBS). The secondary aim was to examine the factors associated with better reporting. A literature search in PubMed, PsychINFO, EMBASE, Scopus, and the Cochrane Controlled Register of Trials was conducted to include randomized controlled trials (RCT), quasi-RCTs and parallel group trials. A total of 22 trials were included in the final analysis. Among the TIDieR 12 items, 6.6 ± 1.9 items were fully reported by all studies. None of the studies completely reported all intervention descriptors. The main areas where reporting required improvement were providing adequate details of the materials and procedures of the interventions, intervention personalization, and intervention modifications during the study. The quality of intervention reporting remained the same after vs. before the release of the TIDieR guidelines. Receiving funds from industrial organizations (p = 0.02) and having the study recorded within a registry platform (p = 0.08) were associated with better intervention reporting. Nutritional weight management interventions in MBS care are still below the desirable standards for reporting. The present study highlights the need to improve adequate reporting of such interventions, which would allow for greater replicability, evaluation through evidence synthesis studies, and transferability into clinical practice., (© 2024.

Background: Despite COVID-19 infection being less severe in children compared to adults, vaccination for children from the age of 6 months onwards is recommended in many countries to reduce symptom severity and prevent severe disease. However, vaccination against COVID-19 for children remains controversial and uptake has been low., Aims: To assess and compare the rate of change of parent-reported COVID-19 vaccine uptake in children aged 5 to 11 years and motivators of vaccine acceptance and non-vaccination among parents/guardians in Canada and Australia., Methods: As part of the iCARE study, two cross-sectional representative samples in Canada and Australia were collected between May 20 and September 12, 2022 (i.e., 5 and 9 months after the COVID-19 vaccine rollout for children 5-11 years) using online panels. Parents/guardians reported the vaccine status of their children and motivators for vaccine acceptance and non-vaccination. General linear models were used to estimate differences between countries in terms of vaccine uptake and motivators across time., Results: Parent-reported vaccine uptake for children 5-11 years didn't increase over the study period (T 1  = 87 %,T 2  = 86 %; OR = 0.83; 95 %CI = 0.45-1.54) and was overall lower in Canada (60.8 %) compared to Australia (71.6 %)(OR = 0.56; 95 %CI = 0.33-0.96). In both countries the socioeconomic characteristics of parents who didn't vaccinate their children were similar and having information on either the short- or long-term side effects of the vaccine were important motivators. However, vaccine effectiveness was more important in Canada and trust in the company that developed the vaccine and a recommendation from the child's doctor were more important motivators in Australia., Conclusion: Parent-reported vaccine uptake for children 5-11 years plateaued early in the vaccine rollout. The main motivators for parents of unvaccinated children varied between the two countries but information on vaccine safety and effectiveness were common to both countries. Findings may inform future tailored vaccine communication efforts and pandemic planning in Australia and Canada to optimize vaccine uptake for primary school children., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: [Kim L Lavoie reports financial support was provided by Canadian Institutes of Health Research.

Background: The COVID-19 pandemic and its prevention policies have taken a toll on Canadians, and certain subgroups may have been disproportionately affected, including those with non-communicable diseases (NCDs; e.g., heart and lung disease) due to their risk of COVID-19 complications and women due to excess domestic workload associated with traditional caregiver roles during the pandemic., Aims/objectives: We investigated the impacts of COVID-19 on mental health, lifestyle habits, and access to healthcare among Canadians with NCDs compared to those without, and the extent to which women with NCDs were disproportionately affected., Methods: As part of the iCARE study ( www.icarestudy.com ), data from eight cross-sectional Canadian representative samples (total n = 24,028) was collected via online surveys between June 4, 2020 to February 2, 2022 and analyzed using general linear models., Results: A total of 45.6% (n = 10,570) of survey respondents indicated having at least one physician-diagnosed NCD, the most common of which were hypertension (24.3%), chronic lung disease (13.3%) and diabetes (12.0%). In fully adjusted models, those with NCDs were 1.18-1.24 times more likely to report feeling lonely, irritable/frustrated, and angry 'to a great extent' compared to those without (p's < 0.001). Similarly, those with NCDs were 1.22-1.24 times more likely to report worse eating and drinking habits and cancelling medical appointments/avoiding the emergency department compared to those without (p's < 0.001). Moreover, although there were no sex differences in access to medical care, women with NCDs were more likely to report feeling anxious and depressed, and report drinking less alcohol, compared to men with NCDs (p's < 0.01)., Conclusion: Results suggest that people with NCDs in general and women in general have been disproportionately more impacted by the pandemic, and that women with NCDs have suffered greater psychological distress (i.e., feeling anxious, depressed) compared to men, and men with NCDs reported having increased their alcohol consumption more since the start of COVID-19 compared to women. Findings point to potential intervention targets among people with NCDs (e.g., prioritizing access to medical care during a pandemic, increasing social support for this population and mental health support)., (© 2023.

Objective: In the context of COVID-19, Canadian healthcare workers (HCWs) worked long hours, both to respond to the pandemic and to compensate for colleagues who were not able to work due to infection and burnout. This may have had detrimental effects on HCWs' mental health, as well as engagement in health-promoting behaviours. This study aimed to identify changes in mental health outcomes and health behaviours experienced by Canadian HCWs throughout the COVID-19 pandemic., Methods: Nine representative samples (N total = 1615 HCWs) completed the iCARE survey using an online polling firm between April 2020 (Time 1) and February 2022 (Time 9). Participants were asked about the psychological effects of COVID-19 (e.g., feeling anxious) and about changes in their health behaviours (e.g., alcohol use, physical activity)., Results: A majority of the HCWs identified as female (65%), were younger than 44 years old (66%), and had a university degree (55%). Female HCWs were more likely than male HCWs to report feeling anxious (OR = 2.68 [1.75, 4.12]), depressed (OR = 1.63 [1.02, 2.59]), and irritable (OR = 1.61 [1.08, 2.40]) throughout the first two years of the pandemic. Female HCWs were more likely than their male counterparts to report eating more unhealthy diets (OR = 1.54 [1.02, 2.31]). Significant differences were also revealed by age, education level, income, parental status, health status, and over time., Conclusion: Results demonstrate that the impacts of COVID-19 on HCWs' mental health and health behaviours were significant, and varied by sociodemographic characteristics (e.g., sex, age, income)., (© 2023.

Background: Bariatric surgery leads to profound changes in gut microbiota and dietary patterns, both of which may interact to impact gut-brain communication. Though cognitive function improves postsurgery, there is a large variability in outcomes. How bariatric surgery-induced modifications in the gut microbiota and dietary patterns influence the variability in cognitive function is still unclear., Objectives: To elucidate the associations between bariatric surgery-induced changes in dietary and gut microbiota patterns with cognition and brain structure., Setting: University hospital., Methods: A total of 120 adult patients (≥30 years) scheduled to undergo a primary bariatric surgery along with 60 age-, sex-, and body mass index-matched patients on the surgery waitlist will undergo assessments 3-months presurgery and 6- and 12-month postsurgery (or an equivalent time for the waitlist group). Additionally, 60 age-and sex-matched nonbariatric surgery eligible individuals will complete the presurgical assessments only. Evaluations will include sociodemographic and health behavior questionnaires, physiological assessments (anthropometrics, blood-, urine-, and fecal-based measures), neuropsychological cognitive tests, and structural magnetic resonance imaging. Cluster analyses of the dietary and gut microbiota changes will define the various dietary patterns and microbiota profiles, then using repeated measures mixed models, their associations with global cognitive and structural brain alterations will be explored., Results: The coordinating study site (Centre intégré universitaire de santé et de services sociaux du Nord-de-l'Île-de-Montréal, QC, Canada), provided the primary ethical approval (Research Ethics Board#: MP-32-2022-2412)., Conclusions: The insights generated from this study can be used to develop individually-targeted neurodegenerative disease prevention strategies, as well as providing critical mechanistic information., (Copyright © 2023 American Society for Metabolic and Bariatric Surgery.

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., (© The Author(s) 2023.

Background: Synthesising evidence on the long-term vaccine effectiveness of COVID-19 vaccines (BNT162b2 [Pfizer-BioNTech], mRNA-1273 [Moderna], ChAdOx1 nCoV-19 [AZD1222; Oxford-AstraZeneca], and Ad26.COV2.S [Janssen]) against infections, hospitalisations, and mortality is crucial to making evidence-based pandemic policy decisions., Methods: In this rapid living systematic evidence synthesis and meta-analysis, we searched EMBASE and the US National Institutes of Health's iSearch COVID-19 Portfolio, supplemented by manual searches of COVID-19-specific sources, until Dec 1, 2022, for studies that reported vaccine effectiveness immediately and at least 112 days after a primary vaccine series or at least 84 days after a booster dose. Single reviewers assessed titles, abstracts, and full-text articles, and extracted data, with a second reviewer verifying included studies. The primary outcomes were vaccine effectiveness against SARS-CoV-2 infections, hospitalisations, and mortality, which were assessed using three-level meta-analytic models. This study is registered with the National Collaborating Centre for Methods and Tools, review 473., Findings: We screened 16 696 records at the title and abstract level, appraised 832 (5·0%) full texts, and initially included 73 (0·4%) studies. Of these, we excluded five (7%) studies because of critical risk of bias, leaving 68 (93%) studies that were extracted for analysis. For infections caused by any SARS-CoV-2 strain, vaccine effectiveness for the primary series reduced from 83% (95% CI 80-86) at baseline (14-42 days) to 62% (53-69) by 112-139 days. Vaccine effectiveness at baseline was 92% (88-94) for hospitalisations and 91% (85-95) for mortality, and reduced to 79% (65-87) at 224-251 days for hospitalisations and 86% (73-93) at 168-195 days for mortality. Estimated vaccine effectiveness was lower for the omicron variant for infections, hospitalisations, and mortality at baseline compared with that of other variants, but subsequent reductions occurred at a similar rate across variants. For booster doses, which covered mostly omicron studies, vaccine effectiveness at baseline was 70% (56-80) against infections and 89% (82-93) against hospitalisations, and reduced to 43% (14-62) against infections and 71% (51-83) against hospitalisations at 112 days or later. Not enough studies were available to report on booster vaccine effectiveness against mortality., Interpretation: Our analyses indicate that vaccine effectiveness generally decreases over time against SARS-CoV-2 infections, hospitalisations, and mortality. The baseline vaccine effectiveness levels for the omicron variant were notably lower than for other variants. Therefore, other preventive measures (eg, face-mask wearing and physical distancing) might be necessary to manage the pandemic in the long term., Funding: Canadian Institutes of Health Research and the Public Health Agency of Canada., Competing Interests: Declaration of interests In the past 3 years, SLB has received consultancy and speaker fees from Resplipus, an investigator-generated educational grant from Moderna, and has served on advisory boards for Bayer, Sanofi, Respiplus, and Sojecci, none of which are related to the current Article.

Objective: The INTER-Change program aims to use systematic frameworks to develop adjunct behavioral interventions to enhance long-term behavior change and improve outcomes in patients undergoing bariatric surgery (BS). This paper details the program strategies and how engagement of interested parties is shaping the research., Method: The core elements of this work include: (a) A living systematic review of behavioral weight management (BWM) interventions adjunct to BS; (b) Focus groups of interested parties, including patients, healthcare professionals, and administrators, on different aspects of designing and implementing adjunct behavioral interventions; (c) A patient-generated survey to assess needs for behavioral interventions to support BWM; (d) An international eDelphi study involving interested parties to prioritize intervention components and delivery structures; and (e) An international consensus meeting to construct testing intervention protocol(s)., Results: The systematic review revealed that delivering BWM interventions during the postoperative period resulted in better weight maintenance; however, most interventions reviewed were poorly developed, and none included interested parties. Initial themes from ongoing focus groups highlighted nonweight-related outcomes as being key goals of adjunct behavior change interventions, with a strong emphasis on psychological well-being and health-related behaviors. The patient survey will add patients' feedback on current interventions and expectations. Finally, the eDelphi process and international consensus meeting will integrate all the findings to develop more efficient behavioral interventions and appropriate testing protocol(s)., Conclusions: This integrated knowledge translation approach will help ensure that the behavioral adjunct interventions are relevant to interested parties' needs, well-designed, effective, and more likely to be implemented successfully.

Aims: Depression after bariatric surgery can lead to suboptimal health outcomes. However, it is unclear how depressive symptoms evolve over the 24 months after surgery. We determined the extent depressive symptoms changed up to 24 months after bariatric surgery and how this was impacted by measurement tool and surgical procedure., Methods: We conducted a systematic review and meta-analysis, searching five databases from database inception to June 2021 for studies that prospectively measured depressive symptoms before and up to 24 months after bariatric surgery. Change scores were converted to Hedge's g, and analyses were performed using mixed-effects models. Subgroup analyses examined differences across time of follow-up, measurement tool, and surgical procedure., Findings: Forty-six studies met inclusion criteria (32,342 patients). Meta-analysis indicated a postsurgical reduction in depressive symptom scores that were significant (large effect, g = 0.804; 95% CI: 0.73-0.88, I 2  = 95.7%). Subgroup analyses found that symptom reductions did not differ between the timing of follow-up periods, measurement tool, and surgical procedure., Conclusions: Depressive symptom scores reduced substantially following surgery; comparable decreases occurred 6 through 24 months after surgery. These findings can help inform practitioners of the typical evolution of depressive symptoms following surgery and where deviations from this may require additional intervention., (© 2023 The Authors.

We aimed to explore the relationships between childhood maltreatment and changes in weight, depressive symptoms and eating behavior post-bariatric surgery (BS). Participants ( n = 111, 85% females) were evaluated pre-surgery, and at 6 months (6 M) and 12 months (12 M) post-BS. History of maltreatment was assessed at baseline (Childhood Trauma Questionnaire), and depressive symptoms (Beck Depression Inventory-II) and eating behavior (Dutch Eating Behavior Questionnaire) were assessed at all time points. Participants' mean age and median BMI were 45.1 ± 11.7 years and 46.7 (IQR 42.4-51.9) kg/m 2 , respectively. Histories of emotional (EA), physical (PA) and sexual abuse (SA) and emotional (EN) and physical (PN) neglect were reported by 47.7%, 25.2%, 39.6%, 51.4% and 40.5%, respectively, with 78.4% reporting at least one form of maltreatment. Changes in weight and depressive symptoms were not different between patients with vs. without a history of maltreatment. However, those with vs. without SA demonstrated limited changes in emotional eating (EE) at 12 M, while those without showed improvements. Conversely, patients with vs. without EN showed greater improvements in external eating (ExE) at 6 M, but differences were no longer observed by 12 M. Results indicate that histories of SA and EN are associated with changes in eating behaviors post-BS and have implications for assessment, monitoring and potential intervention development.

Studies have shown that the protection afforded by COVID-19 vaccines against hospitalization and death decreases slowly over time due to the emergence of new variants and waning immunity. Accordingly, booster doses remain critical to minimizing the health impacts of the pandemic. This study examined the prevalence rate, sociodemographic determinants, and motivators of getting a COVID-19 booster vaccine within the Canadian population. We recruited a representative sample of 3001 Canadians aged 18+ years as part of the iCARE study using an online polling form between 20 January and 2 February 2022. Participants self-reported their booster status and were dichotomized into two groups: those who did vs. did not receive at least one booster dose. A total of 67% of participants received a booster dose. Chi-square analyses revealed that older age ( p < 0.001) and having a chronic disease diagnosis ( p < 0.001) were associated with being more likely to get a booster. Boosted individuals reported motivators tied to efficacy and altruism, whereas non-boosted individuals reported motivators tied to efficacy and safety. Results suggest that messaging will require careful tailoring to address the identified behavioral motivators among non-boosted individuals who emphasize safety and efficacy of additional vaccine doses.

COVID-19 research has relied heavily on convenience-based samples, which-though often necessary-are susceptible to important sampling biases. We begin with a theoretical overview and introduction to the dynamics that underlie sampling bias. We then empirically examine sampling bias in online COVID-19 surveys and evaluate the degree to which common statistical adjustments for demographic covariates successfully attenuate such bias. This registered study analysed responses to identical questions from three convenience and three largely representative samples (total N = 13,731) collected online in Canada within the International COVID-19 Awareness and Responses Evaluation Study ( www.icarestudy.com ). We compared samples on 11 behavioural and psychological outcomes (e.g., adherence to COVID-19 prevention measures, vaccine intentions) across three time points and employed multiverse-style analyses to examine how 512 combinations of demographic covariates (e.g., sex, age, education, income, ethnicity) impacted sampling discrepancies on these outcomes. Significant discrepancies emerged between samples on 73% of outcomes. Participants in the convenience samples held more positive thoughts towards and engaged in more COVID-19 prevention behaviours. Covariates attenuated sampling differences in only 55% of cases and increased differences in 45%. No covariate performed reliably well. Our results suggest that online convenience samples may display more positive dispositions towards COVID-19 prevention behaviours being studied than would samples drawn using more representative means. Adjusting results for demographic covariates frequently increased rather than decreased bias, suggesting that researchers should be cautious when interpreting adjusted findings. Using multiverse-style analyses as extended sensitivity analyses is recommended., (© 2022. Springer Nature B.V.)

Background: There is a paucity of literature exploring the role of bariatric surgery in class 1 obesity. We evaluated the 5-year outcomes after bariatric surgery in patients with class 1 obesity, assessing weight loss, resolution/reduction of obesity-related comorbidities, morbidity and mortality., Methods: We performed a single-centre retrospective analysis of patients who underwent bariatric surgery (laparoscopic sleeve gastrectomy [LSG] or laparoscopic Roux-en-Y gastric bypass [LRYGB)]) for class 1 obesity (body mass index [BMI] 30.0-34.9) between January 2012 and February 2019., Results: Thirty-seven patients (35 [95%] female, mean age 44.5 yr [standard error (SE) 11.3 yr], mean preoperative BMI 33.1) were included, of whom 32 underwent LSG and 5 underwent LRYGB. Thirty-five patients were followed for 5 years post-operatively, achieving a mean BMI of 25.6 (SE 1.2) and excess weight loss of 89.4% (SE 15.1%). Remission of hypertension was achieved in 5 of 12 patients (42%), and remission of dyslipidemia was achieved in 7 of 11 patients (64%). Of the 11 patients with diabetes, 7 underwent LSG and 4, LRYGB. At 5 years postoperatively, the mean glycosylated hemoglobin concentration was 6.3%. Four patients in the LSG group developed de novo reflux, 1 patient required conversion to LRYGB, and 1 patient with sleeve stenosis required endoscopic dilatation. There were no deaths in either patient group., Conclusion: At our centre, bariatric surgery for class 1 obesity was safe and had long-term efficacy, with remission or reduction of related comorbidities. Prospective controlled trials are required to confirm these results., Competing Interests: Competing interests: None declared., (© 2022 CMA Impact Inc. or its licensors.)

Purpose: Depression is a multifaceted psychiatric condition that has been associated with suboptimal weight loss following bariatric surgery. Previous variations of Beck Depression Inventory-Second Edition (BDI-II) subscales been proposed, including those identified within bariatric populations; however, it is unclear whether the BDI-II items contained within these subscales would remain consistent after the procedure considering the physical and lifestyle changes that occur following bariatric surgery., Materials and Methods: A two-step analytic approach that comprised of exploratory (EFA) and confirmatory factor analyses (CFA) that aimed to identify a stable factor structure using pre- and 6-month post-surgical BDI-II responses. Baseline BDI-II responses of 149 patients (Group 1) were used to identify an initial EFA model. Five BDI-II models underwent CFA using BDI-II responses of a comparable pre-surgical group (Group 2; n = 142), and 6-month post-surgical data from Group 1., Results: EFA generated a two-factor solution. Of the five CFA models performed, the three-factor model that was initially identified by Hayes (2015) among patients undergoing bariatric surgery demonstrated superior fit across time and between groups., Conclusions: Although the EFA initially identified a two-factor model, CFA determined that a previously defined three-factor model reliably fit both pre- and post-surgical BDI-II responses. This study supports using the Hayes (2015) subscales when monitoring pre- and post-bariatric surgery facets of depression specific to this population. Being able to accurately and reliably monitor depressive symptoms of patients that are undergoing bariatric surgery will allow for the provision and monitoring of targeted interventions aimed at improving their mental and physical health outcomes., (© 2022.

Objective: Given the role of sociocultural gender in shaping human behaviours, the main objective of this study was to examine whether sex and gender-related factors were associated with the public's adherence to COVID-19-recommended protective health behaviours., Design: This was a retrospective analysis of the survey that captured data on people's awareness, attitudes and behaviours as they relate to the COVID-19 policies., Setting: Data from the International COVID-19 Awareness and Responses Evaluation survey collected between March 2020 and February 2021 from 175 countries., Participants: Convenience sample around the world., Main Outcome Measures: We examined the role of sex and gender-related factors in relation to non-adherence of protective health behaviours including: (1) hand washing; (2) mask wearing; and (3) physical distancing. Multivariable logistic regression was conducted to determine the factors associated with non-adherence to behaviours., Results: Among 48 668 respondents (mean age: 43 years; 71% female), 98.3% adopted hand washing, 68.5% mask wearing and 76.9% physical distancing. Compared with males, females were more likely to adopt hand washing (OR=1.97, 95% CI: 1.71 to 2.28) and maintain physical distancing (OR=1.28, 95% CI: 1.22 to 1.34). However, in multivariable sex-stratified models, females in countries with higher Gender Inequality Indexes (GII) were less likely to report hand washing (adjusted OR (aOR)=0.47, 95% CI: 0.21 to 1.05). Females who reported being employed (aOR=0.22, 95% CI: 0.10 to 0.48) and in countries with low/medium GIIs (aOR=0.18, 95% CI 0.06 to 0.51) were less likely to report mask wearing. Females who reported being employed were less likely to report physical distancing (aOR=0.39, 95% CI: 0.32 to 0.49)., Conclusion: While females showed greater adherence to COVID-19 protective health behaviours, gender-related factors, including employment status and high country-wide gender inequality, were independently associated with non-adherence. These findings may inform public health and vaccination policies in current as well as future pandemics., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Introduction: Asthma guided self-management enhances patients' control of their condition under the guidance of the treating physician. The aim of the present study was to understand how physicians perceive, endorse, uptake, and support asthma guided self-management., Methods: We conducted a secondary supplementary analysis of data originally collected as part of a multicenter collective case study in which physicians treating patients with asthma were interviewed. Using reflective thematic analysis, we aimed to explore physicians' understanding of guided asthma self-management as related to four ideas, namely: (a) understanding of the disease management and treatment goals; (b) defining medical frame and guidance; (c) describing the importance of patient-physician relationship; and (d) implementing asthma guided self-management., Results: Evidence indicates that physicians perceived optimal guided self-management as related to patients' adherence to physician's instructions and recommendations, supported by the adjustment of prescribed pharmaceutical therapy contingent upon patient's symptoms. Some physicians also perceived behavior change and environmental control along with the medical recommendations. While physicians' perception of asthma and its treatment were aligned with the recommended guidelines-i.e., patient-centered care approach based on guided self-management, the actual guidance offered to patients remained primarily directive and paternalistic. Non-pharmacological approaches, such as exercise, smoking cessation, patient self-monitoring, and self-management supported by education and written self-management plans, were given little consideration in the context of the recommended treatment plan.

Objective: This scoping review aims to identify and understand the different tools and methods used in studies in the field of human eating behavior to assess, measure, or classify participants' ambivalence toward food and diet, as well as to identify which tools and methods are most frequently employed., Introduction: People's attitudes toward food and eating behaviors are often ambivalent (simultaneously positive and negative), making it harder to change eating behaviors in favor of a healthier diet. This highlights the importance of resolving diet-related ambivalence. Identifying and understanding the different methods used in the literature to assess attitudinal ambivalence toward food and diet will provide researchers with a range of options to choose from for future studies., Inclusion Criteria: We will include peer-reviewed studies as well as preprints that assess the ambivalence of human participants toward food and diet, regardless of sex, age, or other sociodemographic factors. We will exclude studies in which the methods used to assess ambivalence are not detailed or cannot be reproduced, as well as studies that assess the ambivalence of participants toward farming and agricultural methods or toward methods of food production and preparation., Methods: This review will follow the JBI methodology for scoping reviews. Peer-reviewed studies will be retrieved from MEDLINE, PsycINFO, Web of Science, Food Science Source, FSTA, and CINAHL, while preprints will be retrieved from PsyArXiv and MedArXiv. Two independent reviewers will screen the articles. All relevant extracted information will be presented as tables and a descriptive summary of the findings., Competing Interests: The authors declare no conflict of interest., (Copyright © 2022 JBI.)
