The Study of the Correlation Betweenthe on the Diet, Sleep Quality and Perceived Stress among College Students in Taichung during the COVID-19 Pandemic Distance Learning.

Research indicates the COVID-19 epidemic changes people's health and diet, However, this has not yet been well discussed in Taiwan, especially in college students. Therefore, the purpose of this study is to investigate the impact of distance learning on college students' dietary patterns, sleep quality and perception of stress during the COVID-19 epidemic in Taiwan. 265 college students from a university in Taichung were recruited in this study. The self-administered online questionnaire was used to investigate the changes in eating behavior, sleep quality, and perception of stress before and one month after distance learning, and further analyzed the relationship among them. The questionnaire contains demographic information, dietary questionnaires (including six categories of food intake behaviors, convenience food intake frequency), the Pittsburgh Sleep Quality Index (PSQI) and Perceived Stress Scale (Chinese 14-item PSS). The results showed that the proportion of college students to meet the recommended Taiwan Dietary Guidelines amount in vegetables (21.9%), fruits (27.5%), meats and dairy products (15.8%), and nuts and seeds (11.3%) were lower during distance learning. The frequency of convenient food intake was lower during distance learning (13.31 +/- 6.10 points;never to occasionally). During the distance learning period, there was a significant negative correlation between dietary patterns and sleep quality (r = -0.160, p = 0.009), It shows that college students with higher dietary pattern scores have better sleep quality. During the distance learning period, there was a significant positive correlation between sleep quality and perceived stress (r = 0.320, p < 0.001), It shows that college students with higher levels of stress had poorer sleep quality. This study found that the lower the perceived stress of college students, the better their diet and sleep quality;conversely, the higher the perceived stress, the worse their diet and sleep quality. Studies have shown that a healthy, balanced diet can reduce the risk of getting various diseases. Therefore, in the post-epidemic era, it is recommended that schools increase the accessibility and availability of vegetables, fruits, dairy products, nuts and seeds on campus to make it easier for teachers and students to obtain such healthy food in order to achieve the goal of promoting balanced diet.Copyright © 2022 Nutrition Society in Taipei.

The effect of eating behaviour upon BMI in women with gestational diabetes

Aims: Gestational diabetes has been attributed to maternal obesity and suboptimal maternal diet but the relative contribution of maternal eating behaviour is unknown. We compared eating behaviour in women with gestational diabetes and non-pregnant adults, and assessed which eating behaviour traits were most strongly associated with BMI in women with gestational diabetes. Method(s): Participants (total n = 448) including men (n = 67), non-pregnant women (n = 181) and women with gestational diabetes during a singleton pregnancy (n = 200;29 weeks' gestation;NICE / Covid-19 criteria) were recruited prospectively and completed a three-factor eating questionnaire (TFEQ-R18). Associations between BMI and uncontrolled eating (UE), emotional eating (EE) and cognitive restraint (CR) were assessed using linear regression. Result(s): Women with gestational diabetes had significantly lower UE scores compared to men (53% vs 63%;p < 0.001) and non-pregnant women (53% vs 65%;p < 0.001), and lower EE scores compared to non-pregnant women (60% vs 70%;p < 0.001). In men, BMI showed positive associations with UE (Coeff 25.2;95% CI 10.8-39.6;p = 0.001) and EE scores (Coeff 11.9;95% CI 3.3-20.6;p = 0.007) while CR had no significant association. In non-pregnant women, BMI showed positive associations with UE (Coeff 20.7 95% CI 11.4-30.0), p < 0.001) and EE scores (Coeff 7.7;95% CI 1.8-13.6;p = 0.010) and negative associations with CR (Coef-10.6;95% CI -21.1 to -0.1;p = 0.049). In women with gestational diabetes, only EE scores were significantly associated with BMI (Coeff 7.8;95% CI 3.9-11.7;p < 0.001). Conclusion(s): Women with gestational diabetes have favourable eating behaviour compared to men and non-pregnant women. Addressing EE may provide new translational opportunities to reduce BMI in gestational diabetes.

A Study To Understand Public Knowledge And Perception Towards Immunity Food Booster's Consumption During COVID-19 Pandemic

COVID-19 pandemic has brought a significant change in the lives of all population segments. Irrespective of the country, religion, economic status, and position worldwide, a committed thought is developed on "IMMUNITY" and "IMMUNITY BOOSTERS."The nutrition and health portfolio of many populations worldwide reported severe impacts from changing trends in modern lifestyle, food habits, food consumption, and the environment. Defining health remains a crucial task over several decades. The present study is to understand and evaluate the knowledge and purchasing behaviour of the population during COVID-19 time. A survey is conducted through social media platforms with pre-designed and tested questionnaires. Data were collected from 200 respondents. A rapid assessment survey was conducted using Google Forms. Google Form was distributed through various social media platforms such as WhatsApp, Facebook, and LinkedIn in Indian communities residing across the globe. The above data shows that 64% have consumed Vitamin C supplements almost every day for 15 days, 13% for one month, 10% of the respondents more than one month, and 13% took supplements as supplements per the doctor's advice. The results indicate that nearly 73% of the respondents started consuming supplements, 15% sometimes, and 4% of the respondents expressed their consumption was on and off. When questioned in detail, it is mentioned that they have taken supplements. The results depict buying behaviours, reading and understanding the food labels, purchasing supplements and immune boostersCopyright © 2023, Research Journal of Pharmaceutical, Biological and Chemical Sciences.All Rights Reserved.

This article describes experiences of improving complementary feeding practices using a systems approach with particular focus on health systems strengthening. Achievements included: the development of national guidelines for optimum complementary feeding for children 6-23 months of age, inclusion of a specific indicator for complementary feeding in the new National Food and Nutrition Strategy, updated training packages to improve health worker counselling skills and strengthened social behaviour change communication activities. A systems approach requires strong coordination between all partners across sectors to ensure communities benefit from the synergistic effects of complementary interventions, while system strengthening was noted to improve the resilience of the Ministry of Health and Population to withstand the shocks of the COVID-19 pandemic and the subsequent Ukraine crisis.

Effect of telehealth-based versus in-person nutritional and exercise intervention on type II diabetes mellitus improvement and efficiency of human resources utilization in patients with obesity

Aims: Telehealth became a patient necessity during the COVID pandemic and evolved into a patient preference in the post-COVID era. This study compared the % total body weight loss (%TBWL), HbA1c reduction, and resource utilization among patients with obesity and diabetes who participated in lifestyle interventions with or without telehealth. Method(s): A total of 150 patients with obesity and diabetes who were followed every 4-6 weeks either in-person (n = 83) or via telehealth (n = 67), were included. All patients were provided with an individualized nutritional plan that included a weight-based daily protein intake from protein supplements and food, an activity/sleep schedule-based meal times, and an aerobic exercise goal of a 2000-calorie burn/week, customized to patient's preferences, physical abilities, and comorbidities. The goal was to lose 10%TBWL. Telehealth-based follow-up required transmission via texting of weekly body composition measurements and any blood glucose levels below 100 mg/dl for medication adjustments. Weight, BMI, %TBWL, HbA1c (%), and medication effect score (MES) were compared. Patient no-show rates, number of visits, program duration, and drop-out rate were used to assess resource utilization based on cumulative staff and provider time spent (CSPTS), provider lost time (PLT) and patient spent time (PST). Result(s): Mean age was 47.2 +/- 10.6 years and 74.6% were women. Mean Body Mass Index (BMI) decreased from 44.1 +/- 7.7-39.7 +/- 6.7 kg/m2 (p < 0.0001). Mean program duration was 189.4 +/- 169.3 days. An HbA1c% unit decline of 1.3 +/- 1.5 was achieved with a 10.1 +/- 5.1%TBWL. Diabetes was cured in 16% (24/150) of patients. %TBWL was similar in regards to telehealth or in-person appointments (10.6% +/- 5.1 vs. 9.6% +/- 4.9, p = 0.14). Age, initial BMI, MES, %TBWL, and baseline HbA1c had a significant independent effect on HbA1c reduction (p < 0.0001). Program duration was longer for in-person follow-up (213.8 +/- 194 vs. 159.3 +/- 127, p = 0.019). The mean annual telehealth and in-person no-show rates were 2.7% and 11.2%, respectively (p < 0.0001). Mean number of visits (5.7 +/- 3.0 vs. 8.6 +/- 5.1) and drop-out rates (16.49% vs. 25.83%) were lower in telehealth group (p < 0.0001). The CSPTS (440.4 +/- 267.5 min vs. 200.6 +/- 110.8 min), PLT (28.9 +/- 17.5 min vs. 3.1 +/- 1.6 min), and PST (1033 +/- 628 min vs. 113.7 +/- 61.4 min) were significantly longer (p < 0.0001) for the in-person group. Conclusion(s): Telehealth offered comparable %TBWL and HbA1c decline as in-person follow-up, but with a shorter follow-up, fewer appointments, and no-shows. If improved resource utilization is validated by other studies, telehealth should become the standard of care for the management of obesity and diabetes.Copyright © 2023 The Authors.

Adult eating behavior at the beginning of the COVID-19 pandemic

Introduction: Difficulties in accessing food and social distancing triggered more anxiety, stress and consumption of low-cost and ultra-processed foods. Objective(s): To investigate changes in eating behavior and its relationship with socioeconomic aspects. Method(s): Study conducted virtually between May and June 2020 with 949 adults, with questionnaires on socioeconomic data, changes in eating behavior, frequency of food consumption and the TFEQ-21. The analysis was performed descriptively and the TFEQ-21 according to the scores of each factor. The relationship between the variableswas analyzed using Pearson's correlation test. Result(s): 63% considered cooking more food, 41% and 38% said they were more likely to eat with company and in peace, respectively. 38.6% reduced fast-food purchases, but 43.2% increased food consumption and 41.8% consumption of sweets. In women, the higher the BMI, the greater the emotional eating and cognitive restriction (p<0.001). In these, emotional eating was greater if they did not have children or higher education (p<0.001), and the restriction was greater with physical activity, not having a stable relationship, having children (p<0.001), employment and higher education (p<0.05). In men, emotional eating was related to higher BMI (p<0.05) and both variables were related to physical activity (p<0.001). Conclusion(s): Changes such as cooking more, reducing fast food, eating calmly and with company were observed compared to before the pandemic. It is noted that in women there is a greater relationship between restriction and emotional eating with various aspects of the social and economic context.Copyright © 2023 Faculdade de Medicina de Ribeirao Preto - U.S.P..

Risk factors associated with overweight and obesity in children and adolescents during the COVID-19 pandemic in Chile.

The COVID-19 pandemic has caused changes in people's lifestyles, mainly in healthy eating habits and behaviors. Therefore, our objective was to evaluate the association of eating habits, family eating behaviors, lifestyles, and perception of nutritional status with the risk of overnutrition in children and adolescents during the COVID-19 pandemic. A cross-sectional study was conducted on a sample of 661 Chilean children and adolescents. The study tool was an online self-report questionnaire taken during the COVID-19 lockdown. We observed overnutrition in 37.5%. Habits such as sleeping the recommended number of hours by age group and having healthy family behaviors decreased the risk of overnutrition by 49.0% (OR= 0.510, p= <0.001) and 10.8% (OR= 0.892, p= 0.01), respectively. Parents' perception of weight gain during the pande-mic, the distortion of nutritional status and the health risk of their children's nutritional status increased 4.8 (OR= 4.846, p= <0.001), 8.5 (OR= 8.580, p= <0.001) and 3.8 (OR= 3.826, p= <0.001) times, respectively, the risk of overnutrition in children and adolescents. In conclusion, the COVID-19 lockdown and school closures may have affected lifestyles. In addition, the role of parents in the perception of nutritional status and family eating behaviors is fundamental since they could be a predictor of the risk of overnutrition. These findings propose further research to design plans and programs to avoid the consequences related to overweight and obesity.Copyright © 2023, Sociedad Chilena de Nutricion Bromatologia y Toxilogica.

Impacts of the covid-19 pandemic on eating habits and physical activity

Introduction: The COVID-19 pandemic has resulted in numerous restrictions on daily life, including social distancing and home isolation, affecting the population's eating habits and physical activity level. Objective: Addressing the impacts of the COVID-19 pandemic on eating habits and physical activity. Materials and Methods: This is a narrative-type bibliographic review carried out in the Pubmed and ScienceDirect databases, using the associations of the descriptors (DeCS/MeSH): "COVID-19 AND Feeding Behavior ";"COVID- 19 AND Lifestyle " and "COVID-19 AND Exercise ". Results: 14 scientific articles were selected on eating habits and the level of physical activity during the COVID-19 pandemic. Discussion: Evidence has shown that the of COVID-19 pandemic has contributed to an increase in the intake of foods rich in sugars, fats and sodium and a reduction in the consumption of fresh foods, such as fruits, vegetables and fish, and an increase in sedentary lifestyle among the population, favoring a worrying gain in weight, a risk factor for COVID-19 mortality. Regarding physical activity, it was found that the daily sitting time increased from 5 to 8 hours a day and that the practice of physical activity reduced by 24% during home confinement. Conclusion: Although isolation is a necessary measure to protect public health, the results indicate that it changes physical activity and eating habits, as despite families having more time to cook, there was no improvement in the general quality of the diet and an increase in physical inactivity among them.

Eating behaviour, physical activity and mental health by COVID - 19 quarantine in older adults in Trujillo

Introduction: The COVID-19 pandemic led to a quarantine in Peru seeking the greatest social distancing. Objective: To determine the effect of quarantine on eating behavior, physical activity and mental health before and during this period in older adults in Trujillo. Study: Observational, descriptive, longitudinal in 350 older adults, by means of virtual survey on frequency of food consumption, physical activity and changes in mental health, analyzed by chi-square. Findings: The intake of alcoholic beverages and fast food decreased. The level of physical activity decreased significantly. Feelings of loneliness, depression, anxiety, among others, increased. Perception of weight gain and waist size increase was found. Conclusions: COVID-19 quarantine in older adults decreased physical activity, affected mental health and gave perception of weight and waist size increase, without affecting eating behavior.

Food insecurity and eating behavior prior to the COVID-19 pandemic. An exploratory study in Venezuela.

Background: The aim of this research was to explore how food insecurity affected food behavior prior to the COVID-19 pandemic (year 2018-2019) in a sample of people residing in nine administrative regions of Venezuela. Method(s): 1099 people aged between 17 and 75 years participated, with a majority residing in the Andes, Capital and Central regions of the country. A reduced version of a modified national survey on living conditions (Encovi-2017) composed of 11 questions was administered. Estimates with chi square (chi2) were made to verify associations between the characteristics of the sample (age, region of origin and sex) with the approaches of the administered survey. Result(s): A high degree of food insecurity was observed as people reported concerns about food access (88.95%), or lack of them (55.79%), periods of food deprivation and alteration of eating patterns. Those participants under 21 years were more likely to alter their daily intake pattern (p = 0.01), with women being the most affected in terms of the family running out of food in the last three months (p = 0.020) and if in the last trimester a whole day had gone without eating (p = 0.05). Conclusion(s): The study shows that women and young people under 21 years of age or middle-aged adults and inhabitants of the Capital region turn out to be the people most affected by food insecurity as they consumed less food or ate fewer servings per day. The data reveal a worsening of the food situation.Copyright © 2022 Sociedad Espanola de Nutricion Comunitaria. All rights reserved.

COVID-19 Isolation: impact on mental health and eating behaviors.

Introduction: The fear and uncertainty in the face of the unknown, as well as the fear of contagion by the virus, was added to the stress that can cause a mandatory isolation that arose due to the COVID-19 pandemic, which generated changes in mental health and eating behaviors. Objective(s): To characterize the impact of COVID-19 isolation on mental health and food consumption behaviors. Method(s): An exploratory cross-sectional research was conducted, with the application of a previously validated online instrument, consisting of 18 multiple-choice questions related to mental health and eating behaviors during COVID-19 isolation. 1305 surveys that were answered with the prior consent of the participants were collected. The statistical package SPSS version 22 was applied to associate the variables of interest and tests of the chi-squared for nominal scale indicators. Result(s): The confinement situation due to COVID-19 caused sleep disturbances (41.4%), irritability (79.6%), anxiety (71%), fear (87.3%), arguments at home (62.7%), with negative effects on changes in diet (p = .000), generating poor nutrition (48%). The problem was mainly found in women (p = 0.000), young people and young adults (p = 0.000), from urban areas, who live in apartments without access to green areas. Conclusion(s): There are emotional alterations as a result of isolation, which have an impact on eating behaviors. For this reason, it is necessary to work on public health policies that propose strategies for managing stress and associated emotions during a situation of isolation.Copyright © 2023, Editorial Ciencias Medicas.

Dietary habits, physical activity and nutritional state of Early Childhood Schoolchildren in times of the Covid-19 Pandemic.

Background: Child malnutrition is a serious problem in developing countries. Educational interventions are effective since they improve the knowledge and understanding of healthy eating in school children. Identify eating habits of Initial Education students in times of the COVID-19 Pandemic and see their evolution after an educational intervention. Method(s): Quasi-experimental, prospective, longitudinal research that evaluates in two moments (pre and post intervention) the educational module for the promotion of healthy eating and nutrition in children of the Initial Educational Institution Buenos Aires de Villa carried out during October-November. 2020 in Lima-Peru. 33 students from 5-year-old classrooms were selected. The instrument: Krece Plus test questionnaire. Result(s): The participants were 5 years old (78.8%) and 6 years old (21.2%). The average feeding habit increased from 27.3% to 30.3% and the high decreased from 69.7% to 66.7%;in men, high-level eating habits increased while in women they decreased, the variations occurred in 6-year-old students. There were no statistically significant differences in eating habits (Wilcoxon p=0.559). Conclusion(s): More than half of children have eating habits classified as "High". There were differences, although not significant, after the intervention in the "Medium" and "High" eating habits. It was estimated that children at this stage had a great influence from their parents, who modified their eating habits, so it is necessary that they are also involved in the program.Copyright © 2022 Sociedad Espanola de Nutricion Comunitaria.

Evaluation of a nutrition education and cooking programme (NEST) in vulnerable adults who are at high risk of food insecurity

Within Australia, the prevalence of food insecure individuals increased from 2.6 million in 2014-2016 (10.8%) to 3.1 million in 2018- 2020 (12.3%) due to the COVID-19 pandemic.(1) OzHarvest is a not-for-profit organisation that prioritises food salvaging, food waste prevention and nutrition education.(2) OzHarvest's education sector facilitates a programme known as Nutrition Education Skills Training (NEST). NEST is a 6-week programme providing weekly workshops of 2.5-hour duration offering skills training on cooking simple, healthy, and affordable meals to adults at risk of food insecurity. This study aimed to determine the immediate and longerterm impacts of participation in NEST. A quasi-experimental study with pre-post surveys (n = 258) and follow-up surveys (n = 20) was conducted from June 2019 to July 2022. Survey results were obtained from NEST program participants (18 years) from Adelaide Canberra, Melbourne, Newcastle, Queensland, and Sydney. Baseline (pre-) and post-surveys (at program completion) were administered to participants, with an option for a 6-month follow-up survey. Participants were required to complete both surveys to be eligible for this study. Questionnaires included 23 core questions adapted from previous studies,(3) allowing evaluation of nutrition knowledge confidence and self-efficacy, shopping, and food preparation behaviours, and eating behaviours. Food security was assessed using the standard 6-item indicator set for classifying households by food security status level. Using paired t-tests, Shapiro Wilks, and Wilcoxon sign-ranked tests for pre and post survey data, participants demonstrated overall improvement in nutrition knowledge (p < 0.001), confidence and self-efficacy (n = 222;p < 0.001) and food preparation behaviours (p < 0.001). The intake of discretionary foods overall decreased (p < 0.001) while fruit, vegetable and water intake increased (p < 0.001). Food security improved from 57% to 68% immediately within the population (p < 0.001). Using RMANOVA and Shapiro Wilks tests, the 6-month survey results were compared to the pre surveys suggested longer lasting improvements in nutrition knowledge (p < 0.001), cooking confidence (n = 8;p = 0.033), food preparation behaviours (p = 0.003), and increased vegetable intake (p = 0.032) and fruit intake (p = 0.012) Participation in OzHarvest's NEST programme results in short-term improvements in food security levels and dietary behaviours Over the longer term, these changes were sustained but to a lesser degree, indicating that systemic changes are required to address underlying socioeconomic disadvantage.

The need for sensory nutrition research in individuals with smell loss

Millions of people will now suffer from long-term smell loss as a result of infection with the SARS-CoV-2 virus. Smell is an integral component of the flavor of foods, which is one of the primary drivers of ingestive behavior. When individuals lose their sense of smell, they find food to be less flavorful and less enjoyable, which negatively impacts their quality of life. To compensate, many individuals alter their diet by focusing on tastes, chemesthesis (e.g., chili pepper heat, menthol cooling), and the texture of foods to make it more palatable. Some diet alterations, such as increasing salt use, can result in a lower diet quality, and an increased risk for chronic disease. Sensory nutrition is an area of research that focuses on how the chemical senses (e.g. taste, smell, chemesthesis) and oral somatosensation) affect dietary choices and health. Sensory nutrition strategies designed for individuals with smell loss may help improve the flavor and liking of foods while improving diet quality, and are a necessary area of future research to help improve health and quality of life in the growing population with smell loss.Copyright © 2022 The Author(s)

Association between eating behavior and levels of anxiety, stress and depression in students from private universities in Metropolitan Lima, 2021.

Background: The evidence suggests that the COVID-19 pandemic affected eating behavior due to the anxiety it generates in individuals, especially among the younger population;As a result, preferences in unhealthy foods are observed. The objective was to explore the association between eating behavior and levels of anxiety, stress and depression in the population of university students from two private universities in the city of Lima, Peru during the year 2021. Method(s): Cross-sectional study on a sample of 371 participants from two private universities in Peru between October and November 2021. The Healthy Eating Index Questionnaire (IAS) and the Depression, Anxiety and Stress Scales (DASS-21) were used. Result(s): 53.6% of the participants are women, the majority of university students belong to health sciences careers (21.3%). Women more predisposed to have more severe stress, depression and anxiety, compared to men. The IAS questionnaire score was significantly higher in those studying veterinary and health sciences. The categories of eating behavior: needs changes and unhealthy are risk factors for the presence of anxiety. There is a negative relationship between IAS and DASS-21. Conclusion(s): Eating behavior is associated with the presence of stress, depression and anxiety in students from two private universities in Metropolitan Lima in 2021.Copyright © 2022 Sociedad Espanola de Nutricion Comunitaria.

Perceived changes in the mental well-being among Nigerians due to Ramadan Intermittent Fasting during the COVID-19 pandemic.

INTRODUCTION: Muslims fast every year during the month of Ramadan from dawn until dusk. This study examined mental well-being and correlating factors among Nigerian adults who observed Ramadan intermittent fasting (RIF). METHODS: A validated generalized anxiety disorder-2 and Patient Health Questionnaire-2, the four-item spiritual well-being index, and the Islamic intrinsic religiosity questionnaire were used to collect data about mental well-being (depression, anxiety), spirituality, and intrinsic religiosity through a web-based survey between the May 9, 2021 (27th of Ramadan, 1442) and the June 4, 2021 (29th of Shawwal, 1442). We studied the mental well-being of respondents over a period of 4 weeks before Ramadan (BR) and during the 4 weeks of Ramadan between the April 12, 2021 and the May 12, 2021(DR). Multinomial regression analysis was used to determine the factors associated with depression and anxiety. This research did not receive any grant or funding. RESULTS: A total of 770 adult Nigerians who observed RIF study were included in this cross-sectional study. When compared to mental well-being BR, observing RIF by Nigerian adult respondents was associated with a significant improvement in their mental well-being. A higher proportion of respondents felt less depressed DR (61.3% vs. 56.5%. < .001). Interest and pleasure in doing things improved DR than BR (p= 0.007) and respondents felt less nervous and anxious (60.7% vs. 57.1%, respectively; p <.001). Mental well-being was independently associated with sociodemographic characteristics, physical activity, and perceived relationships. CONCLUSIONS: This study found significant improvement in mental well-being DR compared to BR despite the ongoing COVID-19 pandemic. The effect of RIF on mental well-being needs further research with multicentric studies among different sets of ethnic populations.

The association among circadian rhythm, circadian genes and chrononutrition, its effect on obesity: a review of current evidence

Circadian rhythms, also known as circadian clocks, are cyclic endogenous biological patterns of an approximately 24-hour cycle which regulate the timing of physiology, metabolism, and behavior. Recent research in the field of circadian science has suggested that the timing of food intake may also play a role in markers of health, in addition to food choice and food quantity. There is emerging evidence suggesting that the timing of dietary intake, so-called chrono-nutrition, may be influenced by an individual<apos;>s chronotype. For example, the evening type has been linked to unhealthy diet, which could indicate a higher possibility of obesity. On the other hand, the continuum of chronotype diversity is largely mediated by genes. The presence of single nucleotide polymorphisms (SNP) of clock genes have been associated with obesity, chronotype, metabolic disturbances, and dietary habits (e.g., breakfast skipping, meal timing, energy/macronutrient intake). In this review, we outline the current knowledge of the interactions between clock genes, chronotype, dietary intake and chrono-nutrition.Additionally, it is emphasized that the COVID-19 pandemichas had a significant impact on the circadian system, dietary choices and meal timing. For this reason, the current review aims to focus on how chronotype/sleep and chrono-nutrition are affected during the COVID-19 pandemic.Copyright © 2022 Informa UK Limited, trading as Taylor & Francis Group.

Obesity and COVID-19: insights from two pandemics.

This review article discusses the pathophysiological mechanisms of the development of coronavirus infection in obese patients. It has been shown that obesity is considered as the most important risk factor for the development of many comorbid diseases, including severe forms and deaths as a result of a new coronavirus infection. The higher incidence and severity of a new coronavirus infection in obese patients is based on a complex of factors, the main of which are an increase in cardiovascular risk, including a tendency to thrombosis, a decrease in the efficiency of the respiratory system, impaired immune response, and the presence of chronic inflammatory state. The article discusses non-drug approaches and issues of pharmacological therapy in patients with obesity in the context of a pandemic of a new coronavirus infection. It is shown that the implementation of national quarantine measures has led to an increase in physical inactivity, the level of stress and a change in the eating behavior of the population, closing a vicious circle and contributing to an increase in body weight. For this reason, the efforts of physicians of therapeutic specialties should be directed primarily to increasing resistance to infection among obese patients and combating physical inactivity. The main groups of drugs that can be used to combat lipotoxicity are listed. It was noted that infectious disease doctors and endocrinologists can use those groups of drugs that affect the most vulnerable pathogenetic triggers for the development of obesity and comorbidities: hunger and satiety processes, decreased insulin sensitivity, development of lipotoxicity and chronic inflammation. It has been proven that the range of positive effects of new antihyperglycemic drugs from the groups of type 1 glucagon-like peptide agonists and type 2 sodium-glucose transporter inhibitors, combined with a well-studied efficacy and safety profile, represents a new opportunity for the treatment of obesity in the context of a coronavirus infection pandemic.Copyright © 2022 Authors.

Association between refraining from going out and weight gain after the spread of COVID-19 infection in Japan: JACSIS study

Objectives: In April 2020, a state of emergency was declared regarding COVID-19, and refraining from going out was requested. Although there is concern about weight gain after the spread of the infection, there are few reports of studies in Japan. The present study examined the association between refraining from going out and weight gain after the spread of COVID-19 infection. Methods: Cross-sectional and longitudinal analyses were conducted. Cross-sectional: Data from an internet survey conducted in August 2020 among the general population in Japan were used. Of the 25482 valid responses, 18116 persons aged 20-64 were included in the analysis. Information on refraining from going out was ascertained by a self-administered questionnaire. The outcome variable, subjective weight gain, was categorized as "increased" or "same as before/reduced" based on the question of subjective weight change in the last month compared to before January 2020. Longitudinal: In addition to cross-sectional data, data from the February 2019, February 2020, and February 2021 surveys were collated;4399 individuals participated in all four time points, of which 4337 were included in the analysis after excluding outliers. Two outcome variables were used: (1) weight change of "> 0 kg" from February 2020 to February 2021, and (2) weight change of "> 0 kg" from February 2020 to February 2021 and subjective weight change of "increased". Logistic regression analysis was used for analysis, adjusting for sex, age, occupation, hospitalization, breakfast deprivation, and snacking (in the longitudinal, the rate of weight change in the year before baseline was also adjusted). In addition, the indirect effect of snacking was examined using the Sobel test. Results: Cross-sectional: 5168 (28.5%) of 18116 subjects reported weight gain. Multivariate-adjusted odds ratios (95% confidence intervals) for weight gain in comparison with "never refrained" were 1.46 (1.16-1.83) for "almost never refrained," 1.87 (1.54-2.27) for "sometimes refrained," and 2.07 (1.71-2.51) for "always refrained" (p-trend < 0.001). Snacking had a significant indirect effect on the association between refraining from going out and weight gain (p < 0.001). Longitudinal (1) No significant association was found (p-trend =0.401). Longitudinal (2) Similar to the cross-sectional, we found a significant association (p-trend =0.003) and a significant indirect effect of snacking (p < 0.001). Conclusions: Our results implied that refraining from going out after the spread of COVID-19 infection contributed to weight gain, and snacking mediated this association.
