Changes in the characteristic of dietary and lifestyle during Covid-19 lockdown in different countries: A systematic review

Due to the covid-19 pandemic, governments were forced to adopt lockdown policies to effectively control the pandemic. These restrictions increased anxiety, depression, and lifestyle changes. This systematic review aims to analyze changes in dietary patterns in the worldwide population during the COVID-19 lockdown. 11 studies were selected from the 1412 founds after searching in three databases. Searching keywords were: "Change dietary”, "COVID-19 dietary” "Confinement dietary”. Inclusion criteria were: studies that collected people's dietary patterns during the COVID-19 lockdown and recorded the consumption of food groups and the variations in lifestyle habits. This research found that people increased their consumption of food. People increased their sedentary hours, slept more but exercised less, leading to gain weight during the lockdown, as well as a poorer sleeping quality and higher anxiety levels.Alternate : Debido a la pandemia de COVID-19, los gobiernos se vieron obligados a tomar medidas de confinamiento para controlar eficazmente el contagio. Sin embargo, después de un tiempo de control al poblado, estas restricciones hicieron la gente tener más ansiedad y depresión, incluso cambiar el estilo de vida.

Unraveling the O3-NOX-VOCs relationships induced by anomalous ozone in industrial regions during COVID-19 in Shanghai.

The COVID-19 pandemic promoted strict restrictions to human activities in China, which led to an unexpected increase in ozone (O3) regarding to nitrogen oxides (NOx) and volatile organic compounds (VOCs) co-abatement in urban China. However, providing a quantitative assessment of the photochemistry that leads to O3 increase is still challenging. Here, we evaluated changes in O3 arising from photochemical production with precursors (NOX and VOCS) in industrial regions in Shanghai during the COVID-19 lockdowns by using machine learning models and box models. The changes of air pollutants (O3, NOX, VOCs) during the COVID-19 lockdowns were analyzed by deweathering and detrending machine learning models with regard to meteorological and emission effects. After accounting for effects of meteorological variability, we find increase in O3 concentration (49.5%). Except for meteorological effects, model results of detrending the business-as-usual changes indicate much smaller reduction (-0.6%), highlighting the O3 increase attributable to complex photochemistry mechanism and the upward trends of O3 due to clear air policy in Shanghai. We then used box models to assess the photochemistry mechanism and identify key factors that control O3 production during lockdowns. It was found that empirical evidence for a link between efficient radical propagation and the optimized O3 production efficiency of NOX under the VOC-limited conditions. Simulations with box models also indicate that priority should be given to controlling industrial emissions and vehicle exhaust while the VOCs and NOX should be managed at a proper ratio in order to control O3 in winter. While lockdown is not a condition that could ever be continued indefinitely, findings of this study offer theoretical support for formulating refined O3 management in industrial regions in Shanghai, especially in winter.

A Longitudinal Study on COVID-19 Confinement and Impact on Physical Activity of Medical Students of Rawalpindi

ABSTRACT Objective: To assess the impact of COVID-19 confinement on different aspects of physical activity and sedentary time of medical students with special emphasis on gender. Study Design: This was a longitudinal study in which two samples were taken, one during the confinement period and one after it, to assess the differences between the time spent on physical activity and sedentary time. Place and During of Study: This study was conducted on a total of 300 medical students from two medical colleges of Rawalpindi. The study extended from Apr till Jun 2021 over a period of two months. Methodology: Modified International Physical Activity Questionnaire (IPAQ) was used as a data collection tool. The respondents filled the questionnaire twice. First during COVID-19 confinement and the second, after the confinement ended. Results: A total of 300 individuals were selected to fill in the questionnaire, 200 of them filled in the first questionnaire. The second questionnaire was, however, filled by only 146 individuals and the rest were lost to follow-up. The 146 participants in our study were all students in medical schools in Rawalpindi/Islamabad Pakistan. Out of the total 43.2%(63) were male, while 56.8%(83) were female. The mean age was 20.18±1.72. Post confinement, the amount of time spent on moderate and vigorous activities by all the individuals increased by 26.7% and 82.5%, respectively. In addition, walking time was increased by 82%, sedentary time was also reduced by 36.4%. Conclusion: Physical activity of both men and women was found to be reduced during COVID-19 confinement along with increased sedentary time as compared to their normal routine.

Impact de la Covid-19 sur la fertilité et la sexualité durant le confinement : quelles pertes de chance ?

La pandémie de Covid-19 liée au virus SARSCoV-2 a imposé un confinement mondial des populations en mars 2020. Outre les effets sur la santé publique et la santé physique, la santé mentale et la santé sexuelle ont été impactées. Les projets personnels des individus ont été bouleversés avec un impact sur les projets de couple et notamment de parentalités. La sexualité des individus s'est adaptée, entraînant des changements importants liés à l'isolement et les incertitudes en lien avec la pandémie mondiale.Alternate : The world population is lockdown in March 2020 because of the COVID-19 pandemic due to the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) virus. The impact on mental and sexual health adds to the effects on public health and physical health. Individuals' projects were disrupted like the parenthood of couples. The sexuality adapted to loneliness, and we observe important reshuffles linked to anxiety and uncertainty of worldwide pandemic.

A Sensitive and Practical Evaluation to Detect Lower-Limb Strength Changes in Geriatrics: The Isometric Knee Extension Test

This study aimed to examine the sensitivity of the isometric knee extension (IKE) test to detect changes in the lower-limb strength of institutionalized older adults after exercise and inactivity periods. Thirty-four and fifteen institutionalized older adults completed the training and inactive periods, respectively. At each time point, the participants completed two testing sessions. In the first session, they performed the IKE test. As a complement to this evaluation, the second testing session was used to assess their functional capacity and handgrip strength. The sensitivity of the IKE test was examined by comparing the changes generated in this test against the repeatability of the protocol. A 4-week multicomponent Vivifrail program was implemented. After that, a subsample of the participants was re-evaluated after a 14-week inactivity period. Significant changes (p < 0.01;ES ≥ 0.27) in the IKE strength for both the dominant (+0.27 N/kg) and non-dominant legs (+0.25 N/kg) were produced after the training intervention. Likewise, significant decrements (p < 0.01;ES ≥ 0.31) were detected after the inactive period for the dominant (−0.29 N/kg) and non-dominant legs (−0.32 N/kg). All mean changes were found to be superior to the variability threshold of the IKE test for both legs, with superior sensitivity for the non-dominant leg (≥73%). Thus, the IKE test is a sensitive and practical tool for detecting changes in the lower-limb strength of institutionalized older adults after exercise and inactivity periods. Because of its applicability, it seems pertinent to implement the IKE test in a geriatric context. © 2023 by the authors.

Évolution du nombre de passages aux urgences pour intoxications aiguës lors des périodes de confinement de Covid-19 en Bourgogne-Franche-Comté

Objectif : Estimer l'évolution du nombre de passages aux urgences pour intoxications aiguës (IA) lors des périodes de confinement en 2020 par rapport à l'année précédente. Matériels et méthode : Une étude rétrospective multicentrique de type transversale a été menée en utilisant les données des résumés de passages aux urgences. Deux périodes ont été étudiées en 2020 : période 1 = 1er confinement et période 2 = 2e confinement et ont été comparées aux mêmes périodes en 2019. Les diagnostics pour IA volontaires ou accidentelles toutes causes ont été définis à partir du code CIM-10. Le critère de jugement principal a été la variation du nombre de passages aux urgences pour IA entre les périodes de confinement en 2020 et les périodes de référence en 2019. Résultats : Comparé à la même période en 2019, le nombre de passages aux urgences pour IA a baissé de 31 % (p = 0,001) pendant le premier confinement et de 18 % (p = 0,07) pendant le deuxième confinement. Le nombre de passages pour IA médicamenteuse a baissé de 3 % (p = 0,035) pendant le deuxième confinement en comparaison à 2019. Les caractéristiques des patients consultant pour IA étaient comparables dans chacune des périodes. Conclusion : Dans cette étude, une diminution du nombre de passages aux urgences pour IA a été observée pendant les périodes de confinement en 2020 par rapport aux mêmes périodes l'année précédente.Alternate abstract: Purpose: The objective of this study is to estimate the change in the number of emergency department (ED) visits for acute poisoning during lockdown periods in 2020 compared to the same previous year. Materials and methods: We conducted retrospective cross-sectional multicenter study using ED visit data. Two periods were studied in 2020, period 1 = first lockdown and period 2 = second lockdown, compared to the same periods in 2019. Acute poisoning diagnosis was defined according to the International Classification of Diseases, Tenth Revision (ICD-10). The study outcome was the variation of the number of ED visits for acute poisoning between lockdown periods in 2020 and the same periods in 2019. Results: Compared to the same periods in 2019, the number of ED visits for acute poisoning decreased by 31% (P = 0.001) during the first lockdown and by 18% (P = 0.07) during the second lockdown. The number of ED visits for drug acute poisoning decreased by 3% (P = 0.035) during the second lockdown. The characteristics of patients visiting the ED were similar over all study periods. Conclusion: In this study, a decreased number of ED visits for acute poisoning was observed during lockdown periods in 2020 compared to the same previous year.

Subjective cognitive decline and anxious/depressive symptoms during the COVID-19 pandemic: what is the role of stress perception, stress resilience, and ß-amyloid?

BACKGROUND: The COVID-19 pandemic may worsen the mental health of people reporting subjective cognitive decline (SCD) and therefore their clinical prognosis. We aimed to investigate the association between the intensity of SCD and anxious/depressive symptoms during confinement and the underlying mechanisms. METHODS: Two hundred fifty cognitively unimpaired participants completed the Hospital Anxiety and Depression Scale (HADS) and SCD-Questionnaire (SCD-Q) and underwent amyloid-ß positron emission tomography imaging with [18F] flutemetamol (N = 205) on average 2.4 (± 0.8) years before the COVID-19 confinement. During the confinement, participants completed the HADS, Perceived Stress Scale (PSS), Brief Resilience Scale (BRS), and an ad hoc questionnaire on worries (access to primary products, self-protection materials, economic situation) and lifestyle changes (sleep duration, sleep quality, eating habits). We investigated stress-related measurements, worries, and lifestyle changes in relation to SCD. We then conducted an analysis of covariance to investigate the association of SCD-Q with HADS scores during the confinement while controlling for pre-confinement anxiety/depression scores and demographics. Furthermore, we introduced amyloid-ß positivity, PSS, and BRS in the models and performed mediation analyses to explore the mechanisms explaining the association between SCD and anxiety/depression. RESULTS: In the whole sample, the average SCD-Q score was 4.1 (± 4.4); 70 (28%) participants were classified as SCD, and 26 (12.7%) were amyloid-ß-positive. During the confinement, participants reporting SCD showed higher PSS (p = 0.035) but not BRS scores (p = 0.65) than those that did not report SCD. No differences in worries or lifestyle changes were observed. Higher SCD-Q scores showed an association with greater anxiety/depression scores irrespective of pre-confinement anxiety/depression levels (p = 0.002). This association was not significant after introducing amyloid-ß positivity and stress-related variables in the model (p = 0.069). Amyloid-ß positivity and PSS were associated with greater HADS irrespective of pre-confinement anxiety/depression scores (p = 0.023; p < 0.001). The association of SCD-Q with HADS was mediated by PSS (p = 0.01). CONCLUSIONS: Higher intensity of SCD, amyloid-ß positivity, and stress perception showed independent associations with anxious/depressive symptoms during the COVID-19 confinement irrespective of pre-confinement anxiety/depression levels. The association of SCD intensity with anxiety/depression was mediated by stress perception, suggesting stress regulation as a potential intervention to reduce affective symptomatology in the SCD population in the face of stressors.

Eating behaviors, eating styles and body mass index during COVID-19 confinement in a college sample: a predictive model.

BACKGROUND: COVID-19 confinement affected lifestyles. There is inconclusive evidence about changes in eating patterns, and there are few studies on the impact on body mass index (BMI), the occurrence of dysfunctional behaviors (binge eating, fat intake), and the predictive role of maladaptive eating styles (emotional, external, and restrained eating). OBJECTIVES: (1) To analyze the differences in binge eating, fat intake, BMI, and maladaptive eating styles before and during COVID-19 confinement, and (2) to analyze whether maladaptive eating styles (before confinement) predicted binge eating, fat intake, and BMI during confinement. METHODS: The sample consisted of 146 Spanish college students, divided into 104 females (71.2%; age: M = 22.20, SD = 2.97) and 42 males (28.8%; age: M = 24.74; SD = 3.53). All completed several dietary measures and BMI twice: before COVID-19 confinement (T1, November 2019) and during COVID-19 confinement (T2, April 2020). RESULTS: BMI and maladaptive eating styles did not change in T2 (vs. T1). However, binge eating and fat intake decreased in T2. Emotional eating at T1 positively predicted BMI and binge eating at T2. External eating at T1 positively (and marginally) predicted fat intake at T2. Restrained eating at T1 positively predicted binge eating at T2, and negatively (and marginally) predicted BMI and fat intake at T2. The model explained 80.5% of the variance in BMI, 41.5% of the variance in binge eating, and 25.8% of the variance in fat intake during COVID-19 confinement. CONCLUSIONS: The COVID-19 confinement had a positive impact on some eating behaviors. Future policies should focus part of their prevention on maladaptive eating styles to curb dysfunctional eating behaviors and BMI problems in times of stress.

The COVID-19 confinement affected the lifestyles of the young population, especially eating behaviors. It is not yet known whether eating problems, such as binge eating and high fat intake, changed during this period in the young people. It is also not known whether the young population perceived changes in their BMI during COVID-19 confinement. In addition, eating styles (emotional eating, restrictive eating, and external eating) may be predictors of this change. The present study found that binge eating and fat intake decreased in COVID-19 confinement, and BMI and eating styles remained stable. Eating styles predicted change in these eating problems (binge eating and fat intake) and change in BMI during this period of elevated stress. Therefore, eating styles may help to understand dietary changes during times of high stress.

Changes in Motor Performance and BMI of Primary School Children over Time-Influence of the COVID-19 Confinement and Social Burden.

During the COVID-19 pandemic, physical inactivity and being overweight increased in children, especially those from lower socioeconomic backgrounds. Additionally, a decrease in motor performance has been increasingly reported; however, there is a lack of meaningful data on the relationship between these findings and socioeconomic status. Therefore, we examined the BMI, BMI z score, the prevalence of overweight/obesity, and motor performance (based on lateral jumping, the standing long jump, and the 6-min run) among three cohorts from timelines before (2016) and during the pandemic (2020, 2021), using a cohort sequential design. Our analysis revealed that all parameters examined showed a significant negative trend over time. For children with a low social burden, the trend was statistically detectable only for lateral jumping and the 6-min run. For children with a high social burden, the prevalence of overweight/obesity increased from 4.2% to 5.4% between 2016 and 2021. The prevalence of being underweight also increased from 3.4% to 4.3% during this time. Motor performance decreased from 11.3% to 12.3%, except in the standing long jump. Children with a high social burden showed significantly lower results (7.4% to 9.6%). Thus, our data confirm an increase in both measurements of overweight/obesity and underweight, as well as a decrease in motor performance under the pandemic conditions, especially in children from socioeconomically deprived backgrounds. These findings affirm the urgent need for action regarding health promotion measures, especially for children with high social burdens.

Les deux faces du confinement. Préoccupations et satisfactions des personnes atteintes de cancer pendant le confinement

Objectif et méthode : Quelle a été l’expérience du confinement (16 mars 2020–11 mai 2020) en France, chez les patients atteints de cancer ? Au travers de questions ouvertes envoyées par messagerie électronique pendant les deux dernières semaines du confinement (27 avril–11 mai 2020), l’enquête BaroCov a étudié, auprès de patients suivis à l’institut Curie, les motifs de préoccupation et de satisfaction. À partir des réponses libres, 12 thématiques de préoccupation et 8 thématiques de satisfaction ont été extraites de manière inductive, à partir desquelles les réponses ont été codées puis analysées statistiquement. Résultats : Deux mille quatre cent soixante-dix-huit patients ont répondu, dont 90 % ont plus de 40 ans et 58,9 % entre 40 et 65 ans. Quatre-vingt-trois pour cent sont des femmes. Cinquante et un pour cent vivent à Paris et en proche banlieue. 61,4 % déclarent être en cours de traitement. Préoccupations : Les préoccupations concernaient la santé chez deux tiers des répondants (63,6 %). Elles avaient rapport avec le cancer chez la moitié (45,5 %), dont 9,8 % sur la poursuite du traitement et 5,7%sur les effets secondaires. La Covid-19 préoccupait un cinquième (18,1 %) des personnes. Un quart des répondants citaient comme thématique soit la vie quotidienne (16,6 %) [ne pas vivre comme d’habitude, l’activité professionnelle, l’argent, le logement, le climat social], soit les proches (12,8 %) [la séparation, leur santé, leur avenir]. Appréciations : Un tiers des répondants (33,7 %) citaient les relations avec les proches et un autre tiers (32 %) les conditions de vie (avec la qualité de vie chez 14,6 %, prendre son temps chez 10 % et la nature chez 7,4 %). Plus de 10 % des personnes (13,5 %) citaient spontanément une thématique liée à la maladie (chez 7,3 %, l’état de santé et chez 6,2 % les soins). La thématique du travail n’apparaissait quasiment pas (2,8 %). Conclusion : Le thème principal cité pendant le confinement n’était pas la Covid-19, mais plutôt les polarités existentielles de la vie face au cancer avec d’un côté la peur et les préoccupations liées à la maladie et de l’autre l’importance de l’entourage et la réévaluation positive de la vie quotidienne. Objective and method: The objective of the Barocov survey was to study cancer patients’ worries and satisfactions during Covid containment in France (March 16 to May 11, 2020). We sent e-mail open questions to patients cared for at Curie Institute. We have coded the responses in 12 worries topics and 8 satisfactions topics before analysing them. Results: 90% of the 2,478 respondents were over 40 years old and 58.9% between 40 and 65. 51% were living in Paris. 61.4% were on treatment. Worries: They concerned health for 63.9% of respondents: cancer for 45.5% (with 9.8% about continuing the treatment and 5.7% about side effects). 18.1% were concerned by Covid-19. 16.6% worried about daily life (unusual life, work, money, housing, social climate) and 12.8% worried about loved ones (not seeing them, health, future) Satisfactions: 33.7% appreciated relationships with loved ones and 32% their life conditions (quality of life for 14.6%, having time for 10%, nature for 7.4%). 13.5% had satisfactions about illness: health for 7.3% and cure for 6.2%. Work satisfaction is rare (2.8%) Conclusion: Covid-19 was not the principal worry but emphasized cancer experience’s polarities: on one side, fear about illness and treatment and on the other loved ones’ support and daily life.

Modifications des relations intrafamiliales dans les familles françaises de jeunes enfants pendant le premier confinement lié à la COVID-19

Résumé Introduction: Dans le cadre de la pandémie liée à la COVID-19, l’Etat français a mis en place des mesures de confinement obligeant les parents à rester chez eux avec leurs enfants, tout en assurant, en plus des tâches quotidiennes et du travail, leur scolarité. Objectif: L’objectif de cette publication est de présenter les modifications des relations parents-enfants et entre conjoints pendant cette période et leurs principales sources selon les parents. Méthode: Un questionnaire en ligne du 28 avril 2020 au 29 mai 2020 a permis le recueil des données de 490 familles françaises ayant au moins un enfant de moins de six ans. Une analyse de contenu du corpus discursif a été réalisée avec le logiciel NVivo (version 10). Un traitement statistique quantitatif (réalisé par le logiciel STATA, version 16.1) a testé les relations entre les variables sociodémographiques, ainsi que celles relatives au vécu des parents, et les relations intrafamiliales « tendues » et « renforcées ». Résultats: Si pour 33,3% des répondants, les relations familiales ne se sont pas modifiées, elles se sont renforcées pour 42,5% et tendues pour près d'un quart (24,3%). Conclusion: Comprendre les sources des tensions vécues par les familles de jeunes enfants pendant le confinement, ainsi que ce qui a permis à d’autres familles de mieux vivre cette situation, peut permettre une mise en place de mesures visant à prendre en charge les conséquences du mal-être généré par la vie confinée et à éviter de troubles psychologiques ultérieurs lors de possibles prochains confinements. Introduction: In the context of the COVID-19 pandemic, the French state implemented containment measures requiring parents to stay at home with their children, while ensuring, in addition to daily tasks and work, their schooling. Objective: The objective of this publication is to present the modifications of parent-child and spousal relationships during this period and on their main sources according to the parents. Method: An online questionnaire from 28 April 2020 to 29 May 2020 collected data from 490 French families with at least one child from birth to six years old. A content analysis of the discursive corpus was carried out with NVivo software (version 10). Quantitative statistical processing (using STATA software, version 16.1) tested the relationships between socio-demographic variables, as well as those relating to the parents' experiences, and "strained" and "strengthened" intrafamily relationships. Results: While for 33.3% of the respondents, family relationships did not change, they became stronger for 42.5% and tense for almost a quarter (24.3%). Conclusion: Understanding the sources of tension experienced by families of young children during lockdown, as well as what enabled other families to better cope with this situation, may enable measures to be implemented to deal with the consequences of the discomfort generated by the lockdown and to avoid further psychological problems during possible future ones.

A Standardized Prospective Memory Evaluation of the Effects of COVID-19 Confinement on Young Students.

The restriction imposed worldwide for limiting the spread of coronavirus disease 2019 (COVID-19) globally impacted our lives, decreasing people's wellbeing, causing increased anxiety, depression, and stress and affecting cognitive functions, such as memory. Recent studies reported decreased working memory (WM) and prospective memory (PM), which are pivotal for the ability to plan and perform future activities. Although the number of studies documenting the COVID-19 effects has recently blossomed, most of them employed self-reported questionnaires as the assessment method. The main aim of our study was to use standardized tests to evaluate WM and PM in a population of young students. A sample of 150 female psychology students was recruited online for the administration of two self-reported questionnaires that investigated psychological wellbeing (DASS-21), prospective, and retrospective memory (PRMQ). Subjects were also administered two standardized tests for WM (PASAT) and PM (MIST). We found increased anxiety, depression, and stress and decreased PM as measured by self-reports. The perceived memory failures agreed with the results from the standardized tests, which demonstrated a decrease in both WM and PM. Thus, COVID-19 restriction has strongly impacted on students' mental health and memory abilities, leaving an urgent need for psychological and cognitive recovery plans.

Exploring Dietary Behavior Changes Due to the COVID-19 Confinement in Colombia: A National and Regional Survey Study.

The aim of this study was to evaluate the impact of coronavirus SARS-Cov2 (COVID-19) confinement measures in Colombia on the dietary behaviors of a large population sample, at national and regional levels. A survey was conducted to assess dietary behaviors during the COVID-19 confinement. The survey involved 2,745 participants, aged 18 years or older, from six regions of the country (Atlántica, Bogotá, Central, Oriental, Orinoquía and Amazonía, and Pacífica). Dietary intake of foods and foods groups in grams per day before and during the confinement was estimated by considering standard serving sizes of foods. One-way ANOVA was used to analyze differences between the regions with regard to dietary behavior changes during the confinement. Differences were deemed significant at p-value < 0.05. Dietary patterns (DPs) before and during the confinement were derived from principal component analysis. Certain dietary habits were adopted by the study population during the confinement (e.g., higher frequency of snacking and home cooking), with significant differences by regions with regard to these habits, as well as regarding culinary processes. The levels of consumption of several foods also changed during the confinement, nationally and regionally. We identified three DPs before the confinement (protein-rich, carbohydrate-rich, and sugar foods patterns) and four DPs during the confinement (westernized, carbohydrate-rich, protein-rich, fish and fruits-vegetable patterns), with an explained total variance of 33 and 45%, respectively. The profile of these DPs varied to some extent between the regions; their adherence to each DP also varied (p-value < 0.001). Our results show that there were marked differences by regions in the dietary behaviors of this population during the confinement, with an overall trend toward unhealthier DPs. These results may help to shape public health nutrition interventions in Colombia during the COVID-19 pandemic and in a post-COVID stage.

Cooking at Home and Adherence to the Mediterranean Diet During the COVID-19 Confinement: The Experience From the Croatian COVIDiet Study.

Introduction: The primary aims of this study were to evaluate the changes in dietary behavior among the Croatian adult population during the COVID-19 outbreak and to explore the impact of confinement on cooking habits. Methods: The study was based on results from COVIDiet_Int cross-sectional study-a part of COVIDiet project (NCT04449731). A self-administered online questionnaire was used to assess the frequency of food consumption, eating habits, and sociodemographic information. A total number of 4,281 participants (80.5% females and 19.4% males) completed the questionnaire. Results: The Mediterranean Diet Adherence Screener (MEDAS) score before the confinement was 5.02 ± 1.97, while during the confinement, the MEDAS score increased to 5.85 ± 2.04. Participants who had higher adherence to the Mediterranean diet (MedDiet) during the confinement were mostly females (88.8%), aged between 20 and 50 years, with the highest level of education (66.3%) and normal BMI (70.6%). The majority of participants maintained their dietary behavior as it was before COVID-19 confinement, while 36.9% decreased their physical activity. Participants with higher MEDAS score were more eager to increase their physical activity. Additionally, higher median values of MEDAS score were noted for participants with body mass index values below 24.9 kg/m2 (6.0 vs. 5.0 for participants with BMI above 25 kg/m2). Participants in all residence places increased their cooking frequency during the confinement (53.8%), which was associated with an increase in vegetables, legumes, as well as fish and seafood consumption. Conclusions: According to our findings, Croatian adults exhibited medium adherence to the MedDiet during the COVID-19 confinement. The results suggest that cooking frequency could be positively associated with overall dietary quality, which is of utmost importance in these demanding times.

Impact of COVID-19 confinement on eating behaviours across 16 European countries: The COVIDiet cross-national study.

We aimed to evaluate the changes in eating behaviours of the adult population across 16 European countries due to the COVID-19 confinement and to evaluate whether these changes were somehow related to the severity of the containment measures applied in each country. An anonymous online self-reported questionnaire on socio-demographic characteristics, validated 14-items Mediterranean diet (MedDiet) Adherence Screener (MEDAS) as a reference of a healthy diet, eating and lifestyle behaviours prior to and during the COVID-19 confinement was used to collect data. The study included an adult population residing in 16 European countries at the time of the survey. Aggregated Stringency Index (SI) score, based on data from the Oxford COVID-19 Government Response Tracker, was calculated for each country at the time the questionnaire was distributed (range: 0-100). A total of 36,185 participants completed the questionnaire (77.6% female, 75.2% with high educational level and 42.7% aged between 21 and 35 years). In comparison to pre-confinement, a significantly higher adherence to the MedDiet during the confinement was observed across all countries (overall MEDAS score prior to- and during confinement: 5.23 ± 2.06 vs. 6.15 ± 2.06; p < 0.001), with the largest increase seen in Greece and North Macedonia. The highest adherence to MedDiet during confinement was found in Spain and Portugal (7.18 ± 1.84 and 7.34 ± 1.95, respectively). Stricter contingency restrictions seemed to lead to a significantly higher increase in the adherence to the MedDiet. The findings from this cross-sectional study could be used to inform current diet-related public health guidelines to ensure optimal nutrition is followed among the population, which in turn would help to alleviate the current public health crisis.

Are Emotional and Behavioral Problems of Infants and Children Aged Younger Than 7 Years Related to Screen Time Exposure During the Coronavirus Disease 2019 Confinement? An Exploratory Study in Portugal.

The coronavirus disease 2019 outbreak forced most of the world's population to be confined at home to prevent contagion. Research reveals that one of the consequences of this confinement for children is an increased amount of time spent using screens (television, computers, and mobile devices, etc.) at home. This exploratory study aims to analyze the association between screen time exposure and emotional/behavioral problems of infants and children aged under 7 years, as manifested during the lockdown period in Portugal due to the coronavirus disease 2019 outbreak. The study was controlled for sociodemographic and confinement variables. A sample of 193 parents of children aged from 6 months to 6 years and 12 months, residing in Portugal, completed a survey about the time and manner of use of screen time exposure of their children. Data were derived on circumstances both before and after the confinement; the survey also explored the child's behavioral and emotional adjustment. The findings revealed a modest relationship between children's exposure time to screens and behavioral and emotional problems on children studied. It was also found that parents may play an important role in children's behavioral and emotional adjustment during the confinement period.

The impact of COVID-19 confinement on the eating habits and lifestyle changes: A cross sectional study.

Novel coronavirus (COVID-19) emerged in December 2019 in the city of Wuhan, China causing severe respiratory infections and resulting in millions admissions to hospital and over a million deaths worldwide. Authorities imposed protective measures including confinement to flatten curves of casualties resulted in sudden lifestyle and eating habit changes. The objectives of this study were to observe the impact of the COVID-19 lockdown on eating behavior and lifestyle of the Kurdish population in Iraqi Kurdistan. A structured cross-sectional study was conducted from 1st to 14th of June when the lockdown finished with three different sections. Section one (6 questions) included socio-demographic information section two (11 questions) composed of dietary behavior information including a) Mediterranean diet (MD) adherence using 14-scaled items with a MD screener tool ranging from 0 to 14 b) and sections three (12 questions) composed of lifestyle habit changes such as physical activity, sleeping behavior, and smoking habit. The total number of included respondents was 2,137. The results showed that 12.0% (256) of participants stated that their lifestyle was improved, whereas 50.9% (1,087) declared their lifestyle deteriorated. In particular, the frequency of physical activity was decreased (McNemar value = 60.53, p <.001) and sleeping hours were significantly increased during lockdown (McNemar value = 447.93, p <.001). Regarding eating habits, it was noticed that 29.3% and 14.3% felt that appetite increased and decreased, respectively. The appetite change during lockdown was significantly associated with age (p =.0001), gender (p =.001), city (p =.007), and BMI (p =.001). Similarly, 32.4% reported weight gain. In conclusion, this study is among the earliest studies showing the effect of COVID-19 on eating behavior and lifestyle changes. COVID-19 confinement had a significant effect on lifestyle particularly reducing physical activity and changing eating habits.

The assessment of lifestyle changes during the COVID-19 pandemic using a multidimensional scale.

INTRODUCTION: Healthy lifestyles are relevant to several diseases and to maintain individuals' mental health. Exposure to epidemics and confinement have been consistently associated with psychological consequences, but changes on lifestyle behaviours remain under-researched. MATERIALS AND METHODS: An online survey was conducted among the general population living in Spain during the COVID-19 home-isolation. In addition to demographic and clinical data, participants self-reported changes in seven lifestyle domains. The Short Multidimensional Inventory Lifestyle Evaluation was developed specifically to evaluate changes during the confinement (SMILE-C). RESULTS: A total of 1254 individuals completed the survey over the first week of data collection. The internal consistency of the SMILE-C to assess lifestyles during confinement was shown (Cronbach's Alpha=0.747). Most participants reported substantial changes on outdoor time (93.6%) and physical activity (70.2%). Moreover, about one third of subjects reported significant changes on stress management, social support, and restorative sleep. Several demographic and clinical factors were associated to lifestyle scores. In the multivariate model, those independently associated with a healthier lifestyle included substantial changes on stress management (p<0.001), social support (p=0.001) and outdoor time (p<0.001), amongst others. In contrast, being an essential worker (p=0.001), worse self-rated health (p<0.001), a positive screening for depression/anxiety (p<0.001), and substantial changes on diet/nutrition (p<0.001) and sleep (p<0.001) were all associated with poorer lifestyles. CONCLUSIONS: In this study, sizable proportions of participants reported meaningful changes in lifestyle behaviours during the COVID-19 pandemic in Spain. Moreover, the SMILE-C was sensitive to detect these changes and presented good initial psychometric properties. Further follow-up studies should collect relevant data to promote healthy lifestyles in pandemic times.

The relationship between chronotype, sleep, and autism symptom severity in children with ASD in COVID-19 home confinement period.

This study aimed to investigate the relationship between chronotype preference/sleep problems and symptom severity of children with Autism spectrum disorder (ASD) during the confinement and social isolation of the COVID-19 outbreak. This study included 46 drug-naive children aged 4-17 y diagnosed with ASD. The Autism Behavior Checklist (AuBC), Children's Sleep Habits Questionnaire (CSHQ), and Children's chronotype questionnaire (CCQ) were filled out before and at the end of the COVID-19 mandated home confinement by the children's parents. Children with ASD during the home confinement reported higher chronotype scores, i.e., eveningness chronotype, sleep problems, and autism symptom scores compared to the normal non-hone confinement state. The chronotype score and sleep problems of children with ASD during the home confinement period varied according to the AuBC score. The sleep problems of the children with ASD during the home confinement period mediated the relationship between chronotype score and severity of autism symptoms. It is essential to validate the role of the mediator effect of sleep problems and chronotype in larger samples of children with ASD with restricted to home confinement during the pandemic period. If sleep problems can be controlled with parental education, pharmacotherapy, and psychotherapeutic interventions, the impact on children with ASD of home confinement can be reduced.
