RESUMEN
BACKGROUND: Coronavirus disease 2019 (COVID-19) vaccination has been associated with reduced outpatient antibiotic prescribing among older adults with laboratory-confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We assessed the impact of COVID-19 vaccination on outpatient antibiotic prescribing in the broader population of older adults, regardless of SARS-CoV-2 infection status. METHODS: We included adults aged ≥65 years who received their first, second, and/or third COVID-19 vaccine dose from December 2020 to December 2022. We used a self-controlled risk-interval design and included cases who received an antibiotic prescription 2-6 weeks before vaccination (pre-vaccination or control interval) or after vaccination (post-vaccination or risk interval). We used conditional logistic regression to estimate the odds of being prescribed (1) any antibiotic, (2) a typical "respiratory" infection antibiotic, or (3) a typical "urinary tract" infection antibiotic (negative control) in the post-vaccination interval versus the pre-vaccination interval. We accounted for temporal changes in antibiotic prescribing using background monthly antibiotic prescribing counts. RESULTS: 469 923 vaccine doses met inclusion criteria. The odds of receiving any antibiotic or a respiratory antibiotic prescription were lower in the post-vaccination versus pre-vaccination interval (aOR, .973; 95% CI, .968-.978; aOR, .961; 95% CI, .953-.968, respectively). There was no association between vaccination and urinary antibiotic prescriptions (aOR, .996; 95% CI, .987-1.006). Periods with high (>10%) versus low (<5%) SARS-CoV-2 test positivity demonstrated greater reductions in antibiotic prescribing (aOR, .875; 95% CI, .845-.905; aOR, .996; 95% CI, .989-1.003, respectively). CONCLUSIONS: COVID-19 vaccination was associated with reduced outpatient antibiotic prescribing in older adults, especially during periods of high SARS-CoV-2 circulation.

BACKGROUND: Daily time spent in sleep, sedentary behaviour (SED), light intensity physical activity (LIPA), and moderate-to-vigorous intensity physical activity (MVPA) are compositional, co-dependent variables. The objectives of this study were to use compositional data analysis to: (1) examine the relationship between the movement behaviour composition (daily time spent in sleep, SED, LIPA and MVPA) and all-cause mortality risk, and (2) estimate the extent to which changing time spent in any given movement behaviour (sleep, SED, LIPA, or MVPA) within the movement behaviour composition was associated with changes in risk of all-cause mortality. METHODS: 2838 adult participants from the 2005-2006 cycle of the U.S. National Health and Nutrition Examination Survey were studied using a prospective cohort design. Daily time spent in SED, LIPA and MVPA were determined by accelerometer. Nightly time spent sleeping was self-reported. Survey data were linked with mortality data through to the end of December 2015. Compositional data analysis was used to investigate relationships between the movement behaviour composition and mortality. RESULTS: The movement behaviour composition was significantly associated with mortality risk. Time spent in MVPA relative to other movement behaviours was negatively associated with mortality risk (HR = .74; 95% CI [.67, .83]) while relative time spent in SED was positively associated with mortality risk (HR = 1.75; 95% CI [1.10, 2.79]). Time displacement estimates revealed that the greatest estimated changes in mortality risk occurred when time spent in MVPA was decreased and replaced with sleep, SED, LIPA or a combination of these behaviours (HRs of 1.76 to 1.80 for 15 min/day displacements). CONCLUSIONS: The daily movement behaviour composition was related to mortality. Replacing time in MVPA or SED with equivalent time from any other movement behaviour was associated with an increase and decrease in mortality risk, respectively.

BACKGROUND: Medications are often needed to manage distressing end-of-life symptoms (eg, pain, agitation). OBJECTIVES: In this study, we describe the variation in prescribing rates of symptom relief medications at the end of life among long-term care (LTC) decedents. We evaluate the extent these medications are prescribed in LTC homes and whether prescribing rates of end-of-life symptom management can be used as an indicator of quality end-of-life care. DESIGN: Retrospective cohort study using administrative health data. SETTING AND PARTICIPANTS: LTC decedents in all 626 publicly funded LTC homes in Ontario, Canada, between January 1, 2017, and March 17, 2020. METHODS: For each LTC home, we measured the percent of decedents who received 1+ prescription(s) for a subcutaneous end-of-life symptom management medication ("end-of-life medication") in their last 14 days of life. We then ranked LTC homes into quintiles based on prescribing rates. RESULTS: We identified 55,916 LTC residents who died in LTC. On average, two-thirds of decedents (64.7%) in LTC homes were prescribed at least 1 subcutaneous end-of-life medication in the last 2 weeks of life. Opioids were the most common prescribed medication (overall average prescribing rate of 62.7%). LTC homes in the lowest prescribing quintile had a mean of 37.3% of decedents prescribed an end-of-life medication, and the highest quintile mean was 82.5%. In addition, across these quintiles, the lowest prescribing quintile had a high average (30.3%) of LTC residents transferred out of LTC in the 14 days compared with the highest prescribing quintile (12.7%). CONCLUSIONS AND IMPLICATIONS: Across Ontario's LTC homes, there are large differences in prescribing rates for subcutaneous end-of-life symptom relief medications. Although future work may elucidate why the variability exists, this study provides evidence that administrative data can provide valuable insight into the systemic delivery of end-of-life care.

OBJECTIVE: To examine changes in the prescribing of end-of-life symptom management medications in long-term care (LTC) homes during the COVID-19 pandemic. DESIGN: Retrospective cohort study using routinely collected health administrative data in Ontario, Canada. SETTING AND PARTICIPANTS: We included all individuals who died in LTC homes between January 1, 2017, and March 31, 2021. We separated the study into 2 periods: before COVID-19 (January 1, 2017, to March 17, 2020) and during COVID-19 (March 18, 2020, to March 31, 2021). METHODS: For each LTC home, we measured the percentage of residents who died before and during COVID-19 who had a subcutaneous symptom management medication prescription in their last 14 days of life. We grouped LTC homes into quintiles based on their mean prescribing rates before COVID-19, and examined changes in prescribing during COVID-19 and COVID-19 outcomes across quintiles. RESULTS: We captured 75,438 LTC residents who died in Ontario's 626 LTC homes during the entire study period, with 19,522 (25.9%) dying during COVID-19. The mean prescribing rate during COVID-19 ranged from 46.9% to 79.4% between the lowest and highest prescribing quintiles. During COVID-19, the mean prescribing rate in the lowest prescribing quintile increased by 9.6% compared to before COVID-19. Compared to LTC homes in the highest prescribing quintile, homes in the lowest prescribing quintile experienced the highest proportion of COVID-19 outbreaks (73.4% vs 50.0%), the largest mean outbreak intensity (0.27 vs 0.09 cases/bed), the highest mean total days with a COVID-19 outbreak (72.7 vs 24.2 days), and the greatest proportion of decedents who were transferred and died outside of LTC (22.1% vs 8.6%). CONCLUSIONS AND IMPLICATIONS: LTC homes in Ontario had wide variations in the prescribing rates of end-of-life symptom management medications before and during COVID-19. Homes in the lower prescribing quintiles had more COVID-19 cases per bed and days spent in an outbreak.

Background: Surgical aortic valve replacement (SAVR) is a key strategy for the treatment of aortic valve disease. However, studies have involved primarily male patients, and whether the benefits of this approach can be extrapolated to female patients is unclear. Methods: Clinical and administrative datasets for 12,207 patients undergoing isolated SAVR in Ontario from 2008 to 2019 were linked. Male and female patients were balanced using inverse probability treatment weighting. Mortality, endocarditis, and major hemorrhagic and thrombotic events, as well as 2 composite outcomes-major adverse cerebral and cardiovascular events (MACCE) and patient-derived adverse cardiovascular and noncardiovascular events (PACE)-and their component events, were compared in the weighted groups with a stratified log-rank test. Results: A total of 7485 male patients and 4722 female patients were included in the study. Median follow-up was 5.2 years in both sexes. All-cause mortality did not differ between sexes (hazard ratio [HR] 0.949 [95% confidence interval {CI} 0.851-1.059]). Male sex was associated with an increased risk of new-onset dialysis (HR 0.689 [95% CI 0.488-0.974]). Female sex was associated with a significantly increased risk of both new-onset heart failure (HR 1.211 [95% CI 1.051-1.394], P = 0.0081) and heart failure hospitalization (HR 1.200 [95% CI 1.036-1.390], P = 0.015). No statistically significant differences were seen in any of the other secondary outcomes between sexes. Conclusions: This population health study demonstrated that survival did not differ between male and female patients undergoing SAVR. Significant sex-related differences were found in the risk of heart failure and new-onset dialysis, but these findings should be considered exploratory and require further study.
Contexte: La chirurgie de remplacement valvulaire aortique est une stratégie importante dans le traitement de la valvulopathie aortique. Cependant, les études ont été menées principalement auprès de patients masculins, et il est difficile d'affirmer si les avantages de cette approche peuvent être extrapolés aux patientes. Méthodologie: Les ensembles de données cliniques et administratives de 12 207 patients ayant subi uniquement une chirurgie de remplacement valvulaire aortique en Ontario entre 2008 et 2019 ont été regroupés. Les groupes de patients hommes et femmes ont été équilibrés à l'aide d'une pondération par probabilité inverse du traitement. La mortalité, l'endocardite et les événements hémorragiques et thrombotiques majeurs en plus de deux critères composés les événements cérébrovasculaires et cardiovasculaires indésirables majeurs et les événements cardiovasculaires et non cardiovasculaires indésirables rapportés par les patients et leurs événements constituants ont été comparés dans les groupes pondérés à l'aide d'un test logarithmique par rangs stratifié. Résultats: Au total, 7485 hommes et 4722 femmes ont été inclus dans l'étude. La durée médiane du suivi était de 5,2 ans chez les femmes comme chez les hommes. La mortalité toutes causes confondues ne différait pas entre les sexes (rapport de risques instantanés [RRI] : 0,949, intervalle de confiance [IC] à 95 % : 0,851 à 1,059). Le sexe masculin était associé à un risque accru d'instauration d'une dialyse (RRI : 0,689; IC à 95 % : 0,488 à 0,974). Le sexe féminin était associé à une augmentation significative du risque d'insuffisance cardiaque inaugurale (RRI : 1,211; IC à 95 % : 1,051 à 1,394; p = 0,0081) et d'hospitalisation pour une insuffisance cardiaque (RRI : 1,200; IC à 95 % : 1,036 à 1,390; p = 0,015). Aucune différence statistiquement significative n'a été notée entre les sexes pour les autres critères secondaires. Conclusions: Cette étude en santé des populations a montré que la survie chez les personnes subissant une chirurgie de remplacement valvulaire aortique ne diffère pas entre les hommes et les femmes. Des différences significatives fondées sur le sexe ont été notées dans le risque d'insuffisance cardiaque et de l'instauration d'une dialyse, mais ces constats doivent être considérés comme exploratoires et faire l'objet d'autres études.
RESUMEN
BACKGROUND: Physician home visits are associated with better health outcomes, yet most patients near the end of life never receive such a visit. Our objectives were to describe the receipt of physician home visits during the last year of life after a referral to home care - an indication that the patient can no longer live independently - and to measure associations between patient characteristics and receipt of a home visit. METHODS: We conducted a retrospective cohort study using linked population-based health administrative databases housed at ICES. We identified adult (aged ≥ 18 yr) decedents in Ontario who died between Mar. 31, 2013, and Mar. 31, 2018, who were receiving primary care and were referred to publicly funded home care services. We described the provision of physician home visits, office visits and telephone management. We used multinomial logistic regression to calculate the odds of receiving home visits from a rostered primary care physician, controlling for referral during the last year of life, age, sex, income quintile, rurality, recent immigrant status, referral by rostered physician, referral during hospital stay, number of chronic conditions and disease trajectory based on the cause of death. RESULTS: Of the 58 753 decedents referred in their last year of life, 3125 (5.3%) received a home visit from their family physician. Patient characteristics associated with higher odds of receiving home visits compared to office-based or telephone-based care were being female (adjusted odds ratio [OR] 1.28, 95% confidence interval [CI] 1.21-1.35), being 85 years of age or older (adjusted OR 2.42, 95% CI 1.80-3.26) and living in a rural area (adjusted OR 1.09, 95% CI 1.00-1.18). Increased odds were associated with home care referrals by the patient's primary care physician (adjusted OR 1.49, 95% CI 1.39-1.58) and referrals occurring during a hospital stay (adjusted OR 1.20, 95% CI 1.13-1.28). INTERPRETATION: A small proportion of patients near the end of life received home-based physician care, and patient characteristics did not explain the low visit rates. Future work on system- and provider-level factors may be critical to improve access to home-based end-of-life primary care.

Background: It is widely accepted that there is a stepwise increase in the risk of acute ischemic stroke with chronic kidney disease (CKD). However, whether the risk of specific ischemic stroke subtypes varies with CKD remains unclear. Objective: To assess the association between ischemic stroke subtypes (cardioembolic, arterial, lacunar, and other) classified using the Trial of ORG 10172 in Acute Stroke Treatment (TOAST) and CKD stage. Design: retrospective cohort study. Setting: Ontario, Canada. Patients: A total of 17 434 adults with an acute ischemic stroke in Ontario, Canada between April 1, 2002 and March 31, 2013, with an estimated glomerular filtration rate (eGFR) measurement or receipt of maintenance dialysis captured in a stroke registry were included. Measurements: Kidney function categorized as an eGFR of ≥60, 30-59, <30 mL/min/1.73 m2, or maintenance dialysis. Ischemic stroke classified by TOAST included arterial, cardioembolic, lacunar, and other (dissection, prothrombotic state, cortical vein/sinus thrombosis, and vasculitis) types of strokes. Methods: Adjusted regression models. Results: In our cohort, 58.9% had an eGFR of ≥60, 34.7% an eGFR of 30-59, 6.0% an eGFR of <30 and 0.5% were on maintenance dialysis (mean age of 73 years; 48% women). Cardioembolic stroke was more common in patients with non-dialysis-dependant CKD (eGFR 30-59: 50.4%, adjusted odds ratio [OR] 1.20, 95% confidence interval [CI]: 1.02, 1.44; eGFR<30: 50.6%, OR 1.21, 95% CI: 1.02, 1.44), whereas lacunar stroke was less common (eGFR 30-59: 22.7% OR 0.85, 95% CI: 0.77, 0.93; eGFR <30: 0.73, 95% CI: 0.61, 0.88) compared with those with an eGFR ≥60. In stratified analyses by age and CKD, lacunar strokes were more frequent in those aged less than 65 years, whereas cardioembolic was higher in those aged 65 years and above. Limitations: TOAST classification was not captured for all patients. Conclusion: Non-dialysis CKD was associated with a higher risk of cardioembolic stroke, whereas an eGFR ≥60 mL/min/1.73 m2 was associated with a higher risk of lacunar stroke. Detailed stroke subtyping in CKD may therefore provide mechanistic insights and refocus treatment strategies in this high-risk population.
Contexte: Il est largement admis qu'il y a une augmentation progressive du risque d'accident vasculaire cérébral ischémique aigu en contexte d'insuffisance rénale chronique (IRC). On ignore cependant si le risque de certains sous-types particuliers d'AVC ischémiques varie en présence d'IRC. Objectif: Évaluer le lien entre le stade d'IRC et certains sous-types d'AVC ischémiques (cardioembolique, artériel, lacunaire et autres) classés selon l'essai TOAST (Trial of ORG 10172 in Acute Stroke Treatment). Type d'étude: Étude de cohorte retrospective. Cadre: Ontario (Canada). Sujets: Ont été inclus 17 434 adultes ayant subi un AVC ischémique aigu en Ontario (Canada) entre le 1er avril 2002 et le 31 mars 2013, et pour lesquels le registre d'AVC comportait une mesure du débit de filtration glomérulaire estimé (DFGe) ou une dialyze chronique. Mesures: La fonction rénale a été classée selon le DFGe (≥ 60 ml/min/1,73 m2 entre 30 et 59 ml/min/1,73 m2 <30 ml/min/1.73 m2) ou une dialyze chronique. Les types d'AVC ischémiques classés par l'essai TOAST comprenaient les AVC artériels, cardioemboliques, lacunaires et autres (dissection, état prothrombotique, thrombose de la veine/sinus cortical, vascularite). Méthodologie: Modèles de régression ajustés. Résultats: Dans notre cohorte (âge moyen de 73 ans; 48% de femmes), 58,9 % des patients avaient un DFGe ≥ 60 ml/min/1,73 m2; 34,7% avaient un DFGe entre 30 et 59 ml/min/1,73 m2; 6,0 % avaient un DFGe < 30 ml/min/1,73 m2 et 0,5 % des patients étaient en dialyze chronique En comparaison des patients ayant un DFGe ≥ 60 ml/min/1,73 m2, les AVC cardioemboliques étaient plus fréquents chez les patients atteints d'IRC sans dialyze (DFGe entre 30 et 59 ml/min/1,73 m2: 50,4%; rapport de cote corrigé [RCc] = 1,20; IC 95 % = 1,02-1,44DFGe < 30 ml/min/1,73 m2: 50,6 %; RCc = 1,21; IC95% = 1,02-1,44) alors que les AVC lacunaires étaient moins fréquents [DFGe entre 30 et 59 ml/min/1,73 m2: 22,7%; RCc = 0,85; IC 95% = 0,77-0,93DFGe < 30 ml/min/1,73 m2: RCc = 0,73; IC 95% = 0,61-0,88]. Dans les analyses stratifiées en fonction de l'âge et de l'IRC, les AVC lacunaires étaient plus fréquents chez les moins de 65 ans tandis que les AVC cardioemboliques étaient plus fréquents chez les plus de 65 ans. Limites: La classification TOAST n'était pas enregistrée pour tous les patients. Conclusion: L'IRC sans dialyze a été associée à un risque plus élevé d'AVC cardioembolique alors qu'un DFGe ≥ 60 ml/min/1.73 m2 a été associé à un risque plus élevé d'AVC lacunaire. Le sous-typage détaillé des AVC en contexte d'IRC pourrait donc fournir des informations mécanistiques et recentrer les stratégies de traitement dans cette population à haut risque.
RESUMEN
Importance: Tamoxifen is commonly used as adjuvant therapy in breast cancer and is proposed to interfere with cytochrome P450 enzyme and P-glycoprotein pathways. Concurrent use with direct oral anticoagulants (DOACs) poses the threat of a potentially dangerous drug-drug interaction by leading to an increase in hemorrhage risk. Objective: To assess the risk of hemorrhage in patients with breast cancer coprescribed a DOAC and tamoxifen compared with a DOAC and an aromatase inhibitor (AI). Design, Setting, and Participants: This population-based, retrospective cohort study was conducted among adults aged 66 years or older who were prescribed tamoxifen (compared with an AI) concurrently with a DOAC in Ontario, Canada, between June 23, 2009, and November 30, 2020, and followed up until December 31, 2020. Interventions: Concurrent prescription of a DOAC and tamoxifen compared with a DOAC and an AI. Main Outcomes and Measures: The primary outcome was major hemorrhage requiring an emergency department visit or hospitalization after prescription. Overlap weighted Cox proportional hazards models, accounting for multiple covariates, were used to assess the association between hemorrhage and tamoxifen or AI use with a DOAC. Results: Among a total of 4753 patients (4679 [98.4%] women; mean [SD] age, 77.4 [7.4] years), 1179 (24.8%) were prescribed tamoxifen, and 3574 (75.2%) were prescribed an AI. Rivaroxaban (2530 [53.2%]) and apixaban (1665 [35.0%]) were the most frequently used DOACs. Patients taking AIs were younger than patients taking tamoxifen (mean [SD] age, 77.1 [7.3] vs 78.3 [7.6] years), with higher Charlson Comorbidity Index (mean [SD], 1.8 [2.4] vs 1.5 [2.2]) and more advanced cancer stage (stages III and IV, 569 [15.9%] vs 127 [10.8%]). During a median follow-up of 166 days (IQR, 111-527 days), tamoxifen was not associated with a higher risk of major hemorrhage (29 of 1179 [2.5%]) compared with an AI (119 of 3574 [3.3%]) when combined with a DOAC (absolute risk difference, -0.8%; weighted hazard ratio, 0.68 [95% CI, 0.44-1.06]). These results were similar in additional analyses using a more liberal definition of hemorrhage, accounting for kidney function, limiting follow-up to 90 days, stratifying by incident and prevalent DOAC users, and accounting for cancer duration and the competing risk of death. Conclusions and Relevance: In this cohort study, findings suggest that among DOAC users, the concurrent use of tamoxifen was not associated with a higher risk of hemorrhage compared with the concurrent use of an AI. These findings should directly inform prescribers regarding the apparent safety of concurrent DOAC and tamoxifen use.

IMPORTANCE: Concussion may exacerbate existing mental health issues. Little evidence exists on whether concussion is associated with the onset of new psychopathologies or long-term mental health problems. OBJECTIVE: To investigate associations between concussion and risk of subsequent mental health issues, psychiatric hospitalizations, self-harm, or suicides. DESIGN, SETTING, AND PARTICIPANTS: This population-based retrospective cohort study including children and youths aged 5 to 18 years with a concussion or orthopedic injury incurred between April 1, 2010, and March 31, 2020, in Ontario, Canada. Participants had no previous mental health visit in the year before the index event for cohort entry and no prior concussion or traumatic brain injury 5 years before the index visit. Data were collected from provincewide health administrative databases. Participants with concussion were included in the exposed cohort, and those with an orthopedic injury were included in the comparison cohort; these groups were matched 1:2, respectively, on age and sex. EXPOSURES: Concussion or orthopedic injury. MAIN OUTCOMES AND MEASURES: The primary outcome was mental health problems, such as psychopathologies and psychiatric disorders, identified from health care visits in emergency departments, hospitalizations, or primary care settings. Secondary outcomes were psychiatric hospitalizations, self-harm health care visits, and death by suicide (identified in health care or vital statistics databases). RESULTS: A total of 152â¯321 children and youths with concussion (median [IQR] age, 13 [10-16] years; 86â¯423 [56.7%] male) and 296â¯482 children and youths with orthopedic injury (median [IQR] age, 13 [10-16] years; 171â¯563 [57.9%] male) were matched by age and sex. The incidence rates of any mental health problem were 11â¯141 per 100â¯000 person-years (exposed group) and 7960 per 100â¯000 person-years (unexposed group); with a difference of 3181 (95% CI, 3073-3291) per 100â¯000 person-years. The exposed group had an increased risk of developing a mental health issue (adjusted hazard ratio [aHR], 1.39; 95% CI, 1.37-1.40), self-harm (aHR, 1.49; 95% CI, 1.42-1.56), and psychiatric hospitalization (aHR, 1.47; 95% CI, 1.41-1.53) after a concussion. There was no statistically significant difference in death by suicide between exposed and unexposed groups (HR, 1.54; 95% CI, 0.90-2.61). CONCLUSIONS AND RELEVANCE: Among children and youths aged 5 to 18 years, concussion was associated with an increased risk of mental health issues, psychiatric hospitalization, and self-harm compared with children and youths with an orthopedic injury.

This study determined if meeting the Canadian 24-Hour Movement Guidelines recommendations are associated with all-cause mortality. Participants were 3471 adults from the 2005-2006 U.S. National Health and Nutrition Examination Survey followed for mortality over 11 years. They were classified as meeting or not meeting recommendations for sleep duration, sedentary behaviour, and moderate-to-vigorous physical activity (MVPA). A total of 63.8%, 35.3%, and 41.5% of participants met recommendations for sleep, sedentary behaviour, and physical activity while 12.3% met all 3 recommendations. The hazard ratio (HR) for all-cause mortality in participants meeting the recommendations relative to those not meeting the recommendations were 0.91 (0.72, 1.16) for sleep, 0.92 (0.61, 1.40) for sedentary behaviour, and 0.42 (0.24, 0.74) for MVPA. The HR for meeting none, any 1, any 2, and all 3 recommendations were 1.00, 0.86 (0.65, 1.14), 0.49 (0.28, 0.86), and 0.72 (0.34, 1.50). When the cut-point used to denote acceptable sedentary time was changed from ≤8 to ≤10 hours/day, the HR for meeting none, any 1, any 2, and all 3 recommendations were 1.00, 0.83 (0.59, 1.15), 0.57 (0.34, 0.96), and 0.43 (0.20, 0.93). These findings provide some support of the ability of the 24-hour Movement Guidelines to predict mortality risk. Novelty: The 24-Hour Movement Guidelines provide recommendations for sleep, sedentary behaviour, and physical activity. The findings of this study provide some support of the ability of these new guidelines to predict mortality risk.

This systematic review determined if the composition of time spent in movement behaviours (i.e., sleep, sedentary behaviour (SED), light physical activity, and moderate-to-vigorous physical activity (MVPA)) is associated with health in adults. Five electronic databases were searched in August 2019. Studies were eligible for inclusion if they were peer-reviewed, examined community-dwelling adults, and used compositional data analysis to examine the associations between the composition of time spent in movement behaviours and health outcomes. Eight studies (7 cross-sectional, 1 prospective cohort) of >12 000 unique participants were included. Findings indicated that the 24-h movement behaviour composition was associated with all-cause mortality (1 of 1 analyses), adiposity (4 of 4 analyses), and cardiometabolic biomarkers (8 of 15 analyses). Reallocating time into MVPA from other movement behaviours was associated with favourable changes to most health outcomes and taking time out of SED and reallocating it into other movement behaviours was associated with favourable changes to all-cause mortality. The quality of evidence was very low for all health outcomes. In conclusion, these findings support the notion that the composition of movement across the entire 24-h day matters, and that recommendations for sleep, SED, and physical activity should be combined into a single public health guideline. (PROSPERO registration no.: CRD42019121641.) Novelty The 24-h movement behaviour composition is associated with a variety of health outcomes. Reallocating time into MVPA is favourably associated with health. Reallocating time out of SED is associated with favourable changes to mortality risk.

OBJECTIVES: To compare sedentary time (ST) measured by self-report using a single question from the short-form International Physical Activity Questionnaire (SF-IPAQ), 18-items from the Sedentary Behaviour Questionnaire (SBQ) and objectively using an accelerometer among a large sample of nurses. DESIGN: Cross-sectional. METHODS: Participants wore an ActiGraph GT3X accelerometer (≥4 days, ≥10h/day) and self-reported usual day sitting using the IPAQ and sitting in different modes using the SBQ. Measures were compared using correlations, a Friedman test with Wilcoxon signed-ranks tests for pairwise comparisons, linear regression and Bland-Altman plots. RESULTS: A total of 313 nurses (95% female; mean±SD: age=43±12 years) from 14 hospitals participated. Participants self-reported sitting for a median of 240min/day using the SF-IPAQ and 328min/day using the SBQ. Median ST measured by the ActiGraph was 434min/day. All measures were weakly correlated with each other (ρ=0.31-40, ps<0.001). Limits of agreement were wide between all measures. Significant proportional bias between the ActiGraph and the SF-IPAQ and SBQ existed, suggesting that with greater amounts of ST, there is greater disagreement between the self-report and objective measures. CONCLUSIONS: In a sample of nurses, self-reported ST using the SF-IPAQ and SBQ was significantly lower than that measured by accelerometer. A single-item tool performed more poorly than a multi-item questionnaire. Future studies should consider including both objective and self-report measures of ST, and where possible use a tool that quantifies ST across multiple domains, define a 'usual day' and are meaningful for those with daily schedule variations such as among shift-worker populations.

BACKGROUND: Patients with atrial fibrillation (AF) experience symptom burden, exercise intolerance, weight gain, poor mental health, and diminished quality of life (QoL). Cardiac rehabilitation (CR) is recommended for patients with heart disease, and its benefits are well established, yet clinical guidelines for patients with AF do not include the referral to CR. METHODS: In this matched retrospective, case-control study, we examined the impact of CR on changes in QoL, mental health, and cardiometabolic health indicators in patients with or without persistent or permanent AF. Patients attended CR that addressed risk factor management and provided support services and exercise training twice weekly for 3 months. Height, body mass, waist circumference, blood pressure, and heart rate were measured, and the Short Form-36 and Hospital Anxiety and Depression Scale were administered at baseline and 3 months follow-up. RESULTS: A total of 94 patients (AF, n = 47; no AF, n = 47) (aged 70 ± 8 years) participated. Significant improvements in 2 of the 8 subscales and the Physical Component Summary of the Short Form-36 were observed across groups after CR (P < 0.05). Significant interactions revealed that the effect of CR was greater for energy, emotional well-being, social functioning, pain, and the Physical Component Summary in patients without AF (P < 0.05 for each). No significant improvements in anxiety (AF: -1.3 ± 3.4; no AF: -1.3 ± 4.3), depression (AF: -1.1 ± 2.9; no AF: -0.4 ± 2.7), body mass index (AF: -0.5 ± 1.2; no AF: -0.8 ± 1.5, kg/m2), waist circumference (AF: -1.7 ± 4.6; no AF: 0.4 ± 8.1, cm), or blood pressure (AF: -2.3 ± 17.1/-3.9 ± /9.3; no AF: 1.8 ± 16.4/-0.8 ± /9.3 mm Hg) were observed across groups after CR. CONCLUSIONS: CR improved QoL to a greater extent in patients with heart disease without than with persistent or permanent AF.
