Plain language summary
During the Covid-19 pandemic there was an increase in the number of individuals experiencing a collapsed lung, otherwise known as a pneumothorax (PNX) or pneumomediastinum (PNMD). The reasons for increased PNX are unclear and this systematic review and meta-analysis of 12 studies including 4901 individuals with Covid-19 aimed to determine what may be responsible for this. The results showed that 1629 individuals experienced a PNX and 253 a PNMD, and death was higher amongst those who developed PNX and PNMD. There were strong associations between the occurrence of PNX and PNMD and death. It was concluded that PNX and PNMD significantly increased the risk of dying in individuals with Covid-19 and it was proposed that the term Covid-19-Associated Lung Weakness (CALW) should be applied to those who experience PNX of PNMD. There was some concern that the quality of the research used was very low and so this study could be used by healthcare professionals to understand that PNX and PNMD in Covid-19 patients should be closely monitored and managed.
Abstract
OBJECTIVES To assess mortality and different clinical factors derived from the development of atraumatic pneumothorax (PNX) and/or pneumomediastinum (PNMD) in critically ill patients as a consequence of COVID-19-associated lung weakness (CALW). DESIGN Systematic review with meta-analysis. SETTING Intensive Care Unit (ICU). PARTICIPANTS Original research evaluating patients, with or without the need for protective invasive mechanical ventilation (IMV), with a diagnosis of COVID-19, who developed atraumatic PNX or PNMD on admission or during hospital stay. INTERVENTIONS Data of interest were obtained from each article and analyzed and assessed by the Newcastle-Ottawa Scale. The risk of the variables of interest was assessed with data derived from studies including patients who developed atraumatic PNX or PNMD. MAIN VARIABLES OF INTEREST Mortality, mean ICU stay and mean PaO2/FiO2 at diagnosis. RESULTS Information was collected from 12 longitudinal studies. Data from a total of 4901 patients were included in the meta-analysis. A total of 1629 patients had an episode of atraumatic PNX and 253 patients had an episode of atraumatic PNMD. Despite the finding of significantly strong associations, the great heterogeneity between studies implies that the interpretation of results should be made with caution. CONCLUSIONS Mortality among COVID-19 patients was higher in those who developed atraumatic PNX and/or PNMD compared to those who did not. The mean PaO2/FiO2 index was lower in patients who developed atraumatic PNX and/or PNMD. We propose grouping these cases under the term COVID-19-associated lung weakness (CALW).

Plain language summary
Digital health interventions (DHIs) have the potential to transform the diagnosis, monitoring, and management of chronic cardiovascular conditions. Many DHIs are widely deployed in health systems across the world, with adoption rapidly increasing in response to the coronavirus disease 2019 pandemic. The aim of this study was to provide an updated synthesis of evidence on the effectiveness of telemedicine in the management of cardiovascular diseases. This study is a systematic review and meta-analysis of seventy-two studies with a total of 127,869 participants, of whom 82,818 (65%) were males and 45051 (35%) were females. Results showed reduced cardiovascular-related mortality and hospitalisation for patients with heart failure who received combined remote telemedicine monitoring and consultation compared with usual care. Authors conclude that the findings of their study suggest a definite role for telemedicine in the management of heart failure, particularly in early treatment optimisation, but the value is less clear for long-term management strategy and other cardiovascular diseases. Thus, future research should focus to address the application of these technologies to unselected populations and longer-term effectiveness.
Abstract
BACKGROUND Telemedicine has been increasingly integrated into chronic disease management through remote patient monitoring and consultation, particularly during the COVID-19 pandemic. We did a systematic review and meta-analysis of studies reporting effectiveness of telemedicine interventions for the management of patients with cardiovascular conditions. METHODS In this systematic review and meta-analysis, we searched PubMed, Scopus, and Cochrane Library from database inception to Jan 18, 2021. We included randomised controlled trials and observational or cohort studies that evaluated the effects of a telemedicine intervention on cardiovascular outcomes for people either at risk (primary prevention) of cardiovascular disease or with established (secondary prevention) cardiovascular disease, and, for the meta-analysis, we included studies that evaluated the effects of a telemedicine intervention on cardiovascular outcomes and risk factors. We excluded studies if there was no clear telemedicine intervention described or if cardiovascular or risk factor outcomes were not clearly reported in relation to the intervention. Two reviewers independently assessed and extracted data from trials and observational and cohort studies using a standardised template. Our primary outcome was cardiovascular-related mortality. We evaluated study quality using Cochrane risk-of-bias and Newcastle-Ottawa scales. The systematic review and the meta-analysis protocol was registered with PROSPERO (CRD42021221010) and the Malaysian National Medical Research Register (NMRR-20-2471-57236). FINDINGS 72 studies, including 127 869 participants, met eligibility criteria, with 34 studies included in meta-analysis (n=13 269 with 6620 [50%] receiving telemedicine). Combined remote monitoring and consultation for patients with heart failure was associated with a reduced risk of cardiovascular-related mortality (risk ratio [RR] 0·83 [95% CI 0·70 to 0·99]; p=0·036) and hospitalisation for a cardiovascular cause (0·71 [0·58 to 0·87]; p=0·0002), mostly in studies with short-term follow-up. There was no effect of telemedicine on all-cause hospitalisation (1·02 [0·94 to 1·10]; p=0·71) or mortality (0·90 [0·77 to 1·06]; p=0·23) in these groups, and no benefits were observed with remote consultation in isolation. Small reductions were observed for systolic blood pressure (mean difference -3·59 [95% CI -5·35 to -1·83] mm Hg; p<0·0001) by remote monitoring and consultation in secondary prevention populations. Small reductions were also observed in body-mass index (mean difference -0·38 [-0·66 to -0·11] kg/m2; p=0·0064) by remote consultation in primary prevention settings. INTERPRETATION Telemedicine including both remote disease monitoring and consultation might reduce short-term cardiovascular-related hospitalisation and mortality risk among patients with heart failure. Future research should evaluate the sustained effects of telemedicine interventions. FUNDING The British Heart Foundation.

Plain language summary
The long-term effects of COVID-19 is becoming increasingly documented in adults. Symptoms such as fatigue, headache and depression have all been reported, however data on the possible long-term effects of COVID-19 in children is scarce. The aim of this systematic review and case report was to describe the long-term effects of COVID-19 in five children and support this with other reports in the literature. The results showed that of the five case reports of long COVID, four were girls aged 9-15 years. All subjects reported symptoms lasting between 6-8 months. Most common symptoms were fatigue, difficulty breathing and heart issues. The systematic literature review did not find any publications which documented long COVID in children. It was concluded that children may experience long COVID symptoms and girls may be more susceptible. This study could be used by healthcare professionals to understand that children may also be affected by long COVID and that patients should be monitored for symptoms for at least 6-8 months.
Abstract
AIM: Persistent symptoms in adults after COVID-19 are emerging and the term long COVID is increasingly appearing in the literature. However, paediatric data are scarce. METHODS This paper contains a case report of five Swedish children and the long-term symptoms reported by their parents. It also includes a systematic literature review of the MEDLINE, EMBASE and Web of Science databases and the medRxiv/bioRxiv pre-print servers up to 2 November 2020. RESULTS The five children with potential long COVID had a median age of 12 years (range 9-15) and four were girls. They had symptoms for 6-8 months after their clinical diagnoses of COVID-19. None were hospitalised at diagnosis, but one was later admitted for peri-myocarditis. All five children had fatigue, dyspnoea, heart palpitations or chest pain, and four had headaches, difficulties concentrating, muscle weakness, dizziness and sore throats. Some had improved after 6-8 months, but they all suffered from fatigue and none had fully returned to school. The systematic review identified 179 publications and 19 of these were deemed relevant and read in detail. None contained any information on long COVID in children. CONCLUSION Children may experience similar long COVID symptoms to adults and females may be more affected.

Plain language summary
Regular physical activity may prevent poor outcomes due to COVID-19 in several ways such as improving immune function and reducing inflammation which may contribute to lung damage. However, lockdown measures in many countries have led to a reduction in physical activity. This observational study of 48440 patients with COVID-19 aimed to determine if regular physical activity had a protective effect for severe COVID-19 outcomes. The results showed that patients with COVID-19 who were inactive were more likely to be hospitalised, admitted to intensive care and die compared to individuals who were meeting activity guidelines set by the government in the USA and those who were doing some sort of physical activity. Interestingly individuals who were inactive were more at risk of hospitalisation, admission to intensive care and death than individuals who smoked and who had a chronic disease, indicating the role that physical activity may have in preventing poor outcomes in patients with COVID-19. It was concluded that meeting physical activity guidelines was associated with a reduced risk of severe COVID-19 outcomes. This study could be used by healthcare professionals to understand the importance of recommending activity to individuals during the COVID-19 pandemic.
Abstract
OBJECTIVES To compare hospitalisation rates, intensive care unit (ICU) admissions and mortality for patients with COVID-19 who were consistently inactive, doing some activity or consistently meeting physical activity guidelines. METHODS We identified 48 440 adult patients with a COVID-19 diagnosis from 1 January 2020 to 21 October 2020, with at least three exercise vital sign measurements from 19 March 2018 to 18 March 2020. We linked each patient's self-reported physical activity category (consistently inactive=0-10 min/week, some activity=11-149 min/week, consistently meeting guidelines=150+ min/week) to the risk of hospitalisation, ICU admission and death after COVID-19 diagnosis. We conducted multivariable logistic regression controlling for demographics and known risk factors to assess whether inactivity was associated with COVID-19 outcomes. RESULTS Patients with COVID-19 who were consistently inactive had a greater risk of hospitalisation (OR 2.26; 95% CI 1.81 to 2.83), admission to the ICU (OR 1.73; 95% CI 1.18 to 2.55) and death (OR 2.49; 95% CI 1.33 to 4.67) due to COVID-19 than patients who were consistently meeting physical activity guidelines. Patients who were consistently inactive also had a greater risk of hospitalisation (OR 1.20; 95% CI 1.10 to 1.32), admission to the ICU (OR 1.10; 95% CI 0.93 to 1.29) and death (OR 1.32; 95% CI 1.09 to 1.60) due to COVID-19 than patients who were doing some physical activity. CONCLUSIONS Consistently meeting physical activity guidelines was strongly associated with a reduced risk for severe COVID-19 outcomes among infected adults. We recommend efforts to promote physical activity be prioritised by public health agencies and incorporated into routine medical care.

Plain language summary
Persistence of symptoms following COVID-19 infection is known as long COVID and occurs in up to a third of sufferers and can last for as long as 6 months post infection. Tiredness and reduced capacity to exercise are characteristic of long COVID, however why these symptoms persist in a handful of patients is unknown. Vitamin D deficiency is gaining attention for its potential to improve symptoms of tiredness, however there are few studies examining its relationship with long COVID. This observational study of 149 patients who had been diagnosed with COVID-19 aimed to determine the relationship between symptoms of long COVID, inflammation in the body and vitamin D levels. The results showed that fatigue was common, but there was no association between vitamin D levels and fatigue, inflammation, or capacity to exercise. Interestingly women were more likely to experience fatigue in this study. It was concluded that fatigue and reduced exercise capacity are independent of vitamin D in those who have had COVID-19. This study could be used by healthcare professionals to understand symptoms of long COVID, and that vitamin D may not be effective for those symptoms.
Abstract
The emergence of persistent symptoms following SARS-CoV-2 infection, known as long COVID, is providing a new challenge to healthcare systems. The cardinal features are fatigue and reduced exercise tolerance. Vitamin D is known to have pleotropic effects far beyond bone health and is associated with immune modulation and autoimmunity. We hypothesize that vitamin D levels are associated with persistent symptoms following COVID-19. Herein, we investigate the relationship between vitamin D and fatigue and reduced exercise tolerance, assessed by the Chalder Fatigue Score, six-minute walk test and modified Borg scale. Multivariable linear and logistic regression models were used to evaluate the relationships. A total of 149 patients were recruited at a median of 79 days after COVID-19 illness. The median vitamin D level was 62 nmol/L, with n = 36 (24%) having levels 30-49 nmol/L and n = 14 (9%) with levels <30 nmol/L. Fatigue was common, with n = 86 (58%) meeting the case definition. The median Borg score was 3, while the median distance covered for the walk test was 450 m. No relationship between vitamin D and the measures of ongoing ill-health assessed in the study was found following multivariable regression analysis. These results suggest that persistent fatigue and reduced exercise tolerance following COVID-19 are independent of vitamin D.

Plain language summary
Cases of chronic fatigue have been reported following recovery from Covid-19, in what is termed ‘Long Covid’, with symptoms likened to that of sufferers from chronic fatigue syndrome (CFS) and myalgic encephalomyelitis (ME). How CFS/ME develop and treatments may help to further understand Covid-19. This review study of 111 studies aimed to identify where urgent research is required to help understand the potential of chronic fatigue therapies in Covid-19. The study first reviewed disrupted cellular energy production in ME/CFS and increased presence of damaging oxidants. Current therapies for improving cellular energy production in CFS/ME were then reviewed and Ritalin, ubiquinone and mitoquinol mesylate were heavily featured. Antioxidant therapies in CFS/ME were reviewed and observations would suggest that trials in patients with long covid are needed. It was concluded that research in cellular energy production in CFS/ME has been increasing, however remains contradictory due to a lack of a definitive diagnosis, differing disease severity and the huge differences between patients who suffer from CFS/ME. Further research is required in ME/CFS and Covid-19. This study could be used by health care professionals to understand the importance of monitoring symptoms of fatigue post Covid-19 infection and the possible use of ME/CFS treatments.
Abstract
A significant number of SARS-CoV-2 (COVID-19) pandemic patients have developed chronic symptoms lasting weeks or months which are very similar to those described for myalgic encephalomyelitis/chronic fatigue syndrome. This study reviews the current literature and understanding of the role that mitochondria, oxidative stress and antioxidants may play in the understanding of the pathophysiology and treatment of chronic fatigue. It describes what is known about the dysfunctional pathways which can develop in mitochondria and their relationship to chronic fatigue. It also reviews what is known about oxidative stress and how this can be related to the pathophysiology of fatigue, as well as examining the potential for specific therapy directed at mitochondria for the treatment of chronic fatigue in the form of antioxidants. This study identifies areas which require urgent, further research in order to fully elucidate the clinical and therapeutic potential of these approaches.

Plain language summary
Ross river virus (RRV) is a mosquito borne virus that is thought to be the trigger of myalgic encephalomyelitis (ME) in many Australians. Viruses like RRV are thought to be so successful due to their ability to avoid and often manipulate the hosts immune response. This review of 75 studies aimed to discuss immune evasion strategies employed by RRV and understand the relevance to post viral fatigue and the development of ME. The authors began by explaining how RRV manipulates the hosts immune system to gain entry to cells and replicate. Once the virus has entered the cells, it is thought that it disrupts inflammatory pathways and decreases anti-viral genes. Disruption of inflammation has also been reported to affect energy production in individuals with ME. It was concluded that viruses such as RRV can manipulate the hosts immune system resulting in disruption of energy production. Understanding these pathways and interactions may explain why some individuals go on to develop ME post infection and others do not. Findings may also help to understand ME like symptoms reported by some patients who have recovered from Covid-19. This paper could be used by healthcare professionals to understand the development of ME and fatigue symptoms in individuals who have recovered from viruses such as RRV and Covid-19.
Abstract
Ross River virus (RRV) is an endemic Australian arbovirus, and member of the Alphavirus family that also includes Chikungunya virus (CHIK). RRV is responsible for the highest prevalence of human disease cases associated with mosquito-borne transmission in Australia, and has long been a leading suspect in cases of post-viral fatigue syndromes, with extrapolation of this link to Myalgic Encephalomyelitis (ME). Research into RRV pathogenesis has revealed a number of immune evasion strategies, impressive for a virus with a genome size of 12 kb (plus strand RNA), which resonate with insights into viral pathogenesis broadly. Drawing from observations on RRV immune evasion, mechanisms of relevance to long term idiopathic fatigue are featured as a perspective on infection and eventual ME symptoms, which include considerations of; (1) selective pro-inflammatory gene suppression post antibody-dependent enhancement (ADE) of RRV infection, (2) Evidence from other virus families of immune disruption and evasion post-ADE, and (3) how virally-driven immune evasion may impact on mitochondrial function via target of rapamycin (TOR) complexes. In light of these RRV measures to counter the host immune - inflammatory responses, links to recent discoveries explaining cellular, immune and metabolomic markers of ME will be explored and discussed, with the implications for long-COVID post SARS-CoV-2 also considered. Compelling issues on the connections between virally-induced alterations in cytokine expression, for example, will be of particular interest in light of energy pathways, and how these perturbations manifest clinically.

Plain language summary
The Covid-19 pandemic resulted in national lockdowns, which resulted in isolation within people’s homes. This cross-sectional survey examined changes in eating patterns and behaviour during lockdown. Of the 620 participants included in the study, eating higher energy density foods was more common in females with a higher BMI and higher health anxiety. Although there was a change in emotional eating behaviours across the sample as a whole, it was not in the expected direction, with many participants reporting a decrease in emotional eating after the implementation of lockdown. There were also increases in fruit and vegetable consumption and home prepared foods. Many of these behavioural responses were influenced by pre-lockdown tendencies. Therefore, it is important to consider these when understanding coping strategies during lockdown, and how to support clients as we come out of lockdown.
Expert Review
Conflicts of interest:
None
Take Home Message:
- National lockdowns, as seen during the 2020/21 Covid-19 pandemic, impacted eating behaviour and associations with BMI, eating style and health anxiety.
- Given the new nature of this research, it is not clear what impact confounding factors such as food insecurity had on changing eating behaviours.
- Disproportionate risks were seen in certain demographics and in those shielding due to their heightened risk from Covid-19.
- Retrospective and longitudinal studies to monitor the impact of lockdowns on eating behaviour and health anxiety are needed.

Summary Review:
The role of eating behaviours and psychological responses during lockdown has become an area of interest, particularly with the uncertainty of going into future lockdowns. With Covid-19, and individual’s responses to it, being a relatively new research topic, there is not yet enough evidence for longitudinal outcomes of the findings in these studies. It is also difficult to ascertain the influence of confounding variables prior to the national lockdown, such as food insecurity, not accounted for due to the unpredictable start to the pandemic. There has also been disproportionate risks between certain demographics and their Covid-19 risk, therefore further research on the impact of this on health anxiety and subsequent eating behaviours is required. This highlights a wider need for continued research on the topic.
Clinical practice applications:
Those who had problematic eating behaviours and higher BMI pre lockdown will need to be supported with healthier coping practices if subsequent lockdowns occur, to prevent health related anxiety and consumption of high energy density foods. Furthermore, those who were shielding in their homes were also more likely to show an increase in emotional eating post lockdown. Therefore, clients who spent a large amount of lockdown shielding will need additional support, to develop coping strategies to prevent risk of emotional eating and health anxiety.
Considerations for future research:
Both retrospective and longitudinal studies monitoring the impact of eating behaviours and health anxiety pre and post lockdown are needed. This will help further the evidence base of the potential role of Covid-19 related health anxiety on eating patterns, coping strategies and dietary choices.
Abstract
The global coronavirus pandemic (Covid 19) resulted in national lockdowns where individuals were asked to isolate in their homes to stop the spread of the disease. Using a cross-sectional survey, the current paper aimed to examine self-reported changes in eating patterns and behaviour during the lockdown in the UK, and associations with BMI, demographic variables, eating styles, health anxiety, food insecurity and coping strategies. Participants (N = 620) were recruited online through social media advertising. The results showed that there were self-reported changes to food consumption during the lockdown across the sample. Increases in consumption of HED (high energy density) snack foods during the lockdown was associated with sex, pre-lockdown eating behaviour (emotional eating and uncontrolled eating), and Covid-specific health anxiety. Increases in positive eating practices such as eating more home prepared foods, and fruits and vegetables, were associated with adaptive coping strategies. Higher emotional eating (EE) during the lockdown was associated with a higher BMI, higher pre-lockdown EE and maladaptive coping strategies. Maladaptive coping strategies moderated the relationship between BMI and EE during the lockdown. In particular a higher BMI was associated with higher EE during the lockdown if an individual also had higher maladaptive coping strategies. These findings suggest that changes to eating behaviour may be part of a wider style of maladaptive or adaptive coping, particularly in those with a history of EE or uncontrolled eating. Preparing individuals to adopt more adaptive coping strategies during lockdown situations may be crucial to improving health during subsequent the lockdown events.

Coronavirus disease 2019 (COVID-19) is an infectious disease caused by the respiratory syndrome coronavirus 2 (SARS-CoV-2). To curb the spread of the 2020 pandemic, social distancing, self-isolation and nationwide lockdown measures were put in place. These measures along with hygiene care are recognized as the most effective ways to curb the spread of disease. However; the weakening of social contacts can result in anxiety, frustration, panic attacks, loss or sudden increase of appetite, insomnia, depression, mood swings, delusions, fear, sleep disorders, and suicidal/domestic violence. The purpose of the study is to provide scientific data to help identify risk factors for the psychosocial strain during the COVID-19 outbreak. The study is an international cross-disciplinary online survey and was circulated in April 2020. 1047 replies were analysed from this preliminary phase. The results show a significant difference in all tested parameters and therefore reveal a large burden for mental wellbeing combined with a tendency towards an unhealthy lifestyle during, compared to before, the confinement enforced by the COVID-19 pandemic. These results highlight the importance for policy makers to consider strategies to promote wellbeing during future confinements.
Abstract
Although recognised as effective measures to curb the spread of the COVID-19 outbreak, social distancing and self-isolation have been suggested to generate a burden throughout the population. To provide scientific data to help identify risk factors for the psychosocial strain during the COVID-19 outbreak, an international cross-disciplinary online survey was circulated in April 2020. This report outlines the mental, emotional and behavioural consequences of COVID-19 home confinement. The ECLB-COVID19 electronic survey was designed by a steering group of multidisciplinary scientists, following a structured review of the literature. The survey was uploaded and shared on the Google online survey platform and was promoted by thirty-five research organizations from Europe, North Africa, Western Asia and the Americas. Questions were presented in a differential format with questions related to responses "before" and "during" the confinement period. 1047 replies (54% women) from Western Asia (36%), North Africa (40%), Europe (21%) and other continents (3%) were analysed. The COVID-19 home confinement evoked a negative effect on mental wellbeing and emotional status (P < 0.001; 0.43 ≤ d ≤ 0.65) with a greater proportion of individuals experiencing psychosocial and emotional disorders (+10% to +16.5%). These psychosocial tolls were associated with unhealthy lifestyle behaviours with a greater proportion of individuals experiencing (i) physical (+15.2%) and social (+71.2%) inactivity, (ii) poor sleep quality (+12.8%), (iii) unhealthy diet behaviours (+10%), and (iv) unemployment (6%). Conversely, participants demonstrated a greater use (+15%) of technology during the confinement period. These findings elucidate the risk of psychosocial strain during the COVID-19 home confinement period and provide a clear remit for the urgent implementation of technology-based intervention to foster an Active and Healthy Confinement Lifestyle AHCL).

Plain language summary
The Covid-19 pandemic has altered health behaviours of many individuals resulting in weight gain. This cross-sectional study of 1779 individuals aimed to determine the long-term impact of Covid-19 on health behaviours and weight gain over 5 months. The results showed that most participants (40%) body weight increased alongside increased processed food intake and snacking. 33% of the individuals who gained weight continued to gain weight and 28% maintained their higher weight after lockdown measures were lifted. Take-away meals, processed food intake and stress levels remained high post-lockdown in those who gained weight. It was concluded that lockdown measures may have impacted daily life resulting in weight gain which may perpetuate long-term. This study could be used by healthcare professionals to understand that lockdown measures may have altered eating behaviours resulting in weight gain and that these may need to be uncovered to aid long-term weight loss.
Abstract
Cross-sectional analyses have shown increased obesogenic behaviors and a potential for weight gain during COVID-19 related peak-lockdown (March-May 2020), but longitudinal data are lacking. This study assessed longitudinal changes in body weight and lifestyle behaviors in the US adults during the pandemic. METHODS We used Qualtrics survey to collect self-reported data on body weight, dietary, physical activity, and psychological variables (n = 727) during the peak-lockdown (April/May) and at post-lockdown (September/October). Peak-lockdown weight data were categorized based on the magnitude of weight gained, maintained, or lost, and behavioral differences were examined between categories at two time points. RESULTS Body weight increased (+0.62 kg; p < 0.05) at the post-lockdown period. The body mass index also increased (26.38 ± 5.98 kg/m2 vs. 26.12 ± 5.81 kg/m2; p < 0.01) at the post-lockdown period vs. peak-lockdown period. Close to 40% of participants reported gaining either 1-4 lbs or >5 lbs of body weight during the peak-lockdown, while 18.2% lost weight. Weight-gainers engaged in riskier dietary behaviors such as frequent ultra-processed food intake (p < 0.01) and snacking (p < 0.001), were less active, and reported high stress and less craving control during peak-lockdown. Of those gaining >5 lbs, 33% continued to gain weight after the lockdown eased, while 28% maintain higher body weight. In weight-gainers, takeout meal frequency increased, and high ultra-processed food intake and stress, and low craving control continued to persist after the lockdown eased. CONCLUSION We show that the COVID-19 lockdown periods disrupted weight management among many Americans and that associated health effects are likely to persist.
