Anti-COVID-19 measures threaten our healthy body weight: Changes in sleep and external synchronizers of circadian clocks during confinement

Motivational interviewing for weight management among college students during COVID-19: An exploratory randomized controlled trial

Background

College students encounter challenges in managing their weight. The Coronavirus Disease 2019 (COVID-19) pandemic exacerbated the problem. The purpose of this study was to determine the effect of a motivational interviewing (MI) intervention compared to online education (control) on body composition and self-determination theory constructs among college students with overweight.

Methods

This was a randomized clinical trial of 40 college students comparing an MI versus a control group. The MI group received monthly interviews: three face-to-face interviews before the pandemic, and three video chat interviews after the outbreak of COVID-19 spanning a total of six months. The control group received six, monthly education modules. Body composition was measured by the iDexa and self-determination theory (SDT) variables were assessed with surveys.

Results

Mixed ANOVAs from pre-post revealed significant changes in fat mass (p = .03, η2 = 0.22), lean mass (p < .05, η2 = 0.18), body fat percentage (p < .01, η2 = 0.37), autonomy (p < .01, η2 = 0.38), relatedness (p < .01, η2 = 0.41), amotivation (p = .01, η2 = 0.29), external regulation (p = .02, η2 = 0.23), identified regulation (p = .02, η2 = 0.25), integrated regulation (p < .00, η2 = 0.49), and intrinsic regulation (p = .01, η2 = 0.27).

Conclusions

In this exploratory analysis, MI demonstrated a positive trend in body composition maintenance when compared to online education among overweight college students during a national pandemic. Future studies utilizing MI would enhance the literature by further investigating the relationship between MI and SDT and measuring body composition.Clinicaltrials.gov. identifier: NCT04130386.

Combined effect of work from home and work during nonwork time on sleep disturbance

Background

Owing to the coronavirus disease 2019 pandemic, being exposed to work from home and work during nonwork time simultaneously can lead to sleep disturbance; however, their combined effect is unclear. We aimed to investigate the combined effect of work from home and work during nonwork time on sleep disturbance.

Methods

This study used data from the Sixth Korean Working Condition Survey and included 27,473 paid workers. Logistic regression analysis was conducted to investigate the relationship between work from home, work during nonwork time, and sleep disturbance according to sex. We re-classified participants into 4 groups based on their working from home (No/Yes) and working during nonwork time (No/Yes). The relative excess risk due to interaction was calculated to examine the effect of exposure to both telecommuting and non-regular work hours on sleep disturbance.

Results

Workers exposed to work from home and work during nonwork time had significantly higher risks of sleep disturbance for all, men, and women workers (OR [95% CI]: 1.71 [1.46-2.02], 1.79 [1.43-2.23], and 1.64 [1.29-2.08] for work from home and 3.04 [2.70-3.42], 3.61 [3.09-4.22], and 2.41 [2.01-2.90] for work during nonwork time, respectively). Compared to those who were not exposed to both factors, when workers had both job factors, the ORs (95% CI) of sleep disturbance for all, men, and women were 3.93 (2.80-5.53), 5.08 (3.21-8.03), and 2.91 (1.74-4.87), respectively. The relative excess risk due to interaction of work from home and work during nonwork time was not significant for sleep disturbance.

Conclusions

Work from home and work during nonwork time were each associated with sleep disturbance, but the interaction between the two factors on sleep disturbance was not observed in both men and women.

Meal-timing patterns and chronic disease prevalence in two representative Austrian studies

PURPOSE

This study aimed at describing meal-timing patterns using cluster analysis and explore their association with sleep and chronic diseases, before and during COVID-19 mitigation measures in Austria.

METHODS

Information was collected in two surveys in 2017 (N = 1004) and 2020 (N = 1010) in representative samples of the Austrian population. Timing of main meals, nighttime fasting interval, last-meal-to-bed time, breakfast skipping and eating midpoint were calculated using self-reported information. Cluster analysis was applied to identify meal-timing clusters. Multivariable-adjusted logistic regression models were used to study the association of meal-timing clusters with prevalence of chronic insomnia, depression, diabetes, hypertension, obesity and self-rated bad health status.

RESULTS

In both surveys, median breakfast, lunch and dinner times on weekdays were 7:30, 12:30 and 18:30. One out of four participants skipped breakfast and the median number of eating occasions was 3 in both samples. We observed correlation between the different meal-timing variables. Cluster analysis resulted in the definition of two clusters in each sample (A17 and B17 in 2017, and A20 and B20 in 2020). Clusters A comprised most respondents, with fasting duration of 12-13 h and median eating midpoint between 13:00 and 13:30. Clusters B comprised participants reporting longer fasting intervals and later mealtimes, and a high proportion of breakfast skippers. Chronic insomnia, depression, obesity and self-rated bad health-status were more prevalent in clusters B.

CONCLUSIONS

Austrians reported long fasting intervals and low eating frequency. Meal-timing habits were similar before and during the COVID-19-pandemic. Besides individual characteristics of meal-timing, behavioural patterns need to be evaluated in chrono-nutrition epidemiological studies.

The impact of COVID-19 quarantine on lifestyle indicators in the United Arab Emirates

Introduction

COVID-19 is a virus that has spread rapidly and brought economic and social crises all around the world. The current study aimed to investigate the impact of COVID-19 quarantine on dietary habits, physical activity, food purchasing, smoking, and sleeping patterns in the United Arab Emirates.

Methods

A cross-sectional study was conducted using an online questionnaire between November 1st, 2020 and the end of January 2021. Citizens and residents of the UAE aged ≥ 18 years old were asked to complete an anonymous electronic questionnaire created via Google Forms and distributed on various platforms, such as WhatsApp, Twitter, and email. A total of 1682 subjects participated in the study.

Results

The results included that during the COVID-19 lockdown, more participants (44.4%) reported an increase in weight. This gain seems to be linked to increased food consumption [(Adjusted Odd Ratio) AOR = 1.68, 95% (Confidence Interval) CI = 1.12, 2.54, p = 0.022], decreased physical activity (AOR = 2.25, 95% CI = 1.58, 3.21, p < 0.001), and increased smoking (AOR = 1.90, 95% CI = 1.04, 3.50, p = 0.038). The groups that were most likely to gain weight included those who consumed more cereals (AOR = 1.67, 95% CI = 1.08, 2.57, p = 0.011), had an increased desire for sweets (AOR = 2.19, 95% CI = 1.50, 3.19, p < 0.001), and an increased desire for food (hunger) (AOR = 2.19, 95% CI = 1.53, 3.14, p < 0.001). In contrast, those who exercised more were more likely to lose weight (AOR = 0.61, 95% CI = 0.44, 0.86, p < 0.001) as well as those who slept over 9 h a day (AOR = 1.90, 95% CI = 0.45, 0.88, p = 0.006).

Discussion

Overall, it is essential to promote healthy habits and methods of healthy diet maintenance during stressful and unusual times when people might find it difficult to put effort into their health.

Impact of COVID-19 pandemic on sleep of undergraduate students: A systematic literature review

The 2019 coronavirus pandemic forced the shift to distance education aggravating mental and physical vulnerabilities of undergraduate students, including sleep. This review aims to describe sleep problem rates and prevalence, sleep pattern disruption, sleep duration, sleep quality, insomnia symptoms, psychological and socio-economic factors affecting sleep of undergraduates in 22 countries. A systematic search for articles published from 2020 to 2021 using 'COVID-19,' 'Coronavirus,' 'Pandemic,' 'Sleep,' 'Mental Health,' and 'Students' from PubMed, Scopus, and Cochrane yielded 2550 articles, where 72 were included. Selection criteria were: English full-text available articles, undergraduates and not postgraduates, reported sleep outcomes, and participants not from allied health courses. Risk of bias was assessed using various Joanna Briggs Institute checklists and outcomes were descriptively synthesized. Prevalence of sleep problems was notable, while longitudinal studies showed increased rates. There was significantly increased sleep duration, and sleep pattern disruption during lockdowns. Several psychological, behavioural, environmental, demographic, and socio-economic factors were found to be associated with sleep changes. These highlight the pandemic's impact on sleep of undergraduate students and reveal opportunities for institutions to intervene with policies and programs to promote the well-being of undergraduates. Limitations include recall bias and underrepresentation of other countries. This study is self-funded with registration number RGAO-2021-0071.

Research gaps and opportunities in precision nutrition: an NIH workshop report

Precision nutrition is an emerging concept that aims to develop nutrition recommendations tailored to different people's circumstances and biological characteristics. Responses to dietary change and the resulting health outcomes from consuming different diets may vary significantly between people based on interactions between their genetic backgrounds, physiology, microbiome, underlying health status, behaviors, social influences, and environmental exposures. On 11-12 January 2021, the National Institutes of Health convened a workshop entitled "Precision Nutrition: Research Gaps and Opportunities" to bring together experts to discuss the issues involved in better understanding and addressing precision nutrition. The workshop proceeded in 3 parts: part I covered many aspects of genetics and physiology that mediate the links between nutrient intake and health conditions such as cardiovascular disease, Alzheimer disease, and cancer; part II reviewed potential contributors to interindividual variability in dietary exposures and responses such as baseline nutritional status, circadian rhythm/sleep, environmental exposures, sensory properties of food, stress, inflammation, and the social determinants of health; part III presented the need for systems approaches, with new methods and technologies that can facilitate the study and implementation of precision nutrition, and workforce development needed to create a new generation of researchers. The workshop concluded that much research will be needed before more precise nutrition recommendations can be achieved. This includes better understanding and accounting for variables such as age, sex, ethnicity, medical history, genetics, and social and environmental factors. The advent of new methods and technologies and the availability of considerably more data bring tremendous opportunity. However, the field must proceed with appropriate levels of caution and make sure the factors listed above are all considered, and systems approaches and methods are incorporated. It will be important to develop and train an expanded workforce with the goal of reducing health disparities and improving precision nutritional advice for all Americans.

Effect of COVID-19 outbreak on the diet, body weight and food security status of students of higher education: a systematic review

The COVID-19 pandemic has impacted college students' lifestyles and placed them at a greater risk of obesity and food insecurity. The purpose of the systematic review was to consolidate evidence for the effect of Covid-19 on students' dietary quality, dietary habits, body weight and food security status. A comprehensive literature search was conducted utilising various databases including Google Scholar, MEDLINE, ScienceDirect, Embase and Scopus to identify relevant studies. To be incorporated in this review, studies had to include higher education students, measure the prevalence of food insecurity and assess the dietary and body weight changes during the COVID-19 pandemic. The studies showed that the diet quality of college students was compromised during the pandemic in many nations due to the decrease in the intake of whole grains, dairy products, legumes, nuts, fruits and vegetables and the increase in consumption of alcohol, confectionery products and refined grains. There was an increase in the frequency of cooking, binge eating, breakfast skipping and unhealthy snacking. These modifications, in return, were associated with body weight changes, with no less than 20 to 30 % of students gaining weight during the pandemic. The pandemic also impacted food security status of students, with over 30% being food insecure worldwide. The COVID-19 outbreak has exacerbated the students' diet quality and dietary habits and placed them under high risk of weight gain and food insecurity. Higher education institutions and governments should improve students' access to nutritious foods and incorporate nutrition education interventions in the curricula.

Pandemic experiences and psychopathological aspects in individuals with mood disorders and other mental disorders

Individuals with different personality traits, temperaments, and psychological symptoms have different attitudes toward the pandemic experiences and restrictive measures. The aim of the present study was to evaluate the associations between the psychological factors and the attitudes toward COVID-19, experienced during the third pandemic wave in Italy, in a sample of individuals with psychiatric disorders. Between March and September 2021, 53 patients with mood disorders and other mental disorders completed a survey composed of self-report questionnaires that assessed sleep quality, depressive and hypomanic symptoms, and temperament and personality traits. Positive and negative attitudes toward the pandemic experience were assessed using an ad hoc questionnaire. The results showed that individuals with more severe depressive symptoms were less prone to adhere to government guidelines, and were more convinced that the pandemic was not a real problem. Reduced sleep quality was associated with increased skepticism toward official explanations concerning the causes of COVID-19. Lastly, negative affect and cyclothymic temperament predicted the disposition toward COVID-19 vaccines. In conclusion, these findings highlighted that some psychological aspects and psychiatric symptoms could influence the beliefs about COVID-19 and compliance with government recommendations. Further research is needed to provide indications on how to improve the current healthcare policies.

Will Nothing Be the Same Again?: Changes in Lifestyle during COVID-19 Pandemic and Consequences on Mental Health

Social isolation caused by the COVID-19 pandemic has drastically affected lifestyles: from sedentary behaviors to reduced physical activity, from disrupted sleep patterns to altered dietary habits. As a consequence, serious mental and emotional responses have been registered. There was a significant decline in physical and other meaningful activities of daily living, leisure, social activity, and education. In children, collateral effects of the pandemic include inadequate nutrition with a risk of both overweight and underweight, addiction to screens, lack of schooling, and psychosocial difficulties. Older adults are frequently unable to adapt to lockdown measures and suffer from depression and cognitive complaints. Recent studies focusing on changes in lifestyle during the Covid-19 pandemic and consequences on mental health have been identified in PubMed/Medline, Scopus, Embase, and ScienceDirect. All the available literature has been retrospectively reviewed. The results of the present narrative review suggest that mental distress caused by social isolation seems to be linked not only to personality characteristics but also to several lifestyle components (sleep disruption, altered eating habits, reduced physical activity). This review aims to explore major changes in the lifestyle and quality of life and the impact of these changes on mental health, and to inform clinicians and policymakers about elements that may reduce the negative psychological effects of the quarantine period imposed during this worldwide crisis. There is an urgent need for tailored preventive, diagnostic, and therapeutic mental health interventions for the general population and for higher risk groups.
