Organic food and obesity: factors influencing actual purchase of organic food in COVID-19 pandemic with moderating role of organic food availability

Purpose: Organic food consumption decreases the risk of becoming obese or overweight. This study intends to see the influence of customer perceived value, COVID-19 fear, food neophobia, effort and natural content on the intention to purchase organic food (IPOF) that leads to the actual purchase of organic food (APOF). Moreover, organic food availability is a moderator between IPOF and APOF. Design/methodology/approach: PLS-SEM is used for hypothesis testing. A purposive sampling technique was followed to gather data from organic food consumers in Lahore, Gujranwala and Islamabad and a total of 479 questionnaires were part of the analysis. Findings The outcomes show that customer perceived value, effort and natural content is positively related to IPOF. Despite this, COVID-19 fear and food neophobia are negatively associated with IPOF. IPOF and organic food availability are positively related to APOF. Finally, organic food availability significantly moderated between IPOF and APOF. Practical implications: This study outcome reveals that companies of organic food can recognize customer perceived value, COVID-19 fear, food neophobia, effort, natural content and organic food availability in their decision-making if they determine the actual purchase of organic food. This study offers a valuable policy to companies of organic food to enhance customer's behavior in purchasing organic food in Pakistan. Besides, practitioners and academicians can benefit from this study finding. Originality/value: This initial research integrates customer perceived value, COVID-19 fear, food neophobia, effort, natural content, IPOF and organic food availability to determine APOF in the COVID-19 pandemic. Moreover, consumption value theory is followed to develop the framework.

Comparing the effects of endurance and resistance training programs on some pulmonary, functional, and quality of life indicators in patients with COVID-19 discharged from hospital

Background and purpose: The present study investigated the effect of six weeks of endurance and resistance training on pulmonary indices, physical performance, and quality of life in COVID-19 patients after discharge from hospital. Materials and methods: Thirty six patients with COVID-19 (mean age: 38.76+or-0.98 years, mean weight: 81.86+or-2.88 kg) were selected. At the beginning and end of the study, pulmonary (FEV1, FVC, FEV1/FVC, and MVV), physical (6-minute walk test), quality of life (SF-36), and anthropometry tests were performed. The patients were divided into three groups: Endurance training (45 minutes at 60-75% estimated HR), Resistance training (45 minutes at 40-70% of I-RM), and controls. The intervention was conducted for 6 weeks (3 sessions). One-way ANOVA test was used for statistical analysis. Results: Findings indicated a significant increase in FEV1 (P=0.029), FVC (P=0.047), FEV1/FVC (P=0.043) in the endurance training group compared to the control group, while difference was observed in MVV (P=0.041) and FEV1/FVC (P=0.022) between endurance training and resistance training groups. The 6-minute test distance increased in the endurance training (P=0.0001) and resistance training (P=0.001) groups compared to the control group, but no difference was observed between the training groups (P=0.48). Endurance and resistance training programs induced significant improvements in physical performance (P=0.024 and P=0.09, respectively) and general health (P=0.022 and P=0.015, respectively) dimensions compared to the control group. Conclusion: Moderate-intensity endurance training can improve pulmonary function, physical performance, and quality of life in patients with COVID-19 after discharge from hospital and can be used in rehabilitation programs of these patients.

Association between diet quality and BMI with side effects of pfizer-biontech COVID-19 vaccine and SARS-CoV-2 immunoglobulin G titers. (Special Issue: The relationship between nutrition and COVID-19.)

Purpose: The nutritional and anthropometric status can be essential in determining their immune response to vaccines. The purpose of this paper was to investigate the association between diet quality and anthropometric indices with the side effects of the Pfizer-BioNTech COVID-19 vaccine and the SARS-CoV-2 immunoglobulin G titer among Kurdish adults. Design/methodology/approach: This cross-sectional survey-based study was conducted between December 2021 and February 2022. This paper included data on 115 adults, 20-89 years old, from the Kurdistan region. Dietary information was collected using a short food frequency questionnaire, and diet quality was assessed using a plant-based healthy diet score. A blood test was performed to measure the SARS-CoV-2 immunoglobin G (IgG) titer after the vaccination's first and second doses. Findings: Overweight and obese subjects reported more local pain, myalgia, headache, local bruising and local reactions after receiving the first dose of the vaccine (p = 0.04). People on a less healthy diet reported more local pain, myalgia and headache (p = 0.04) and more local bruising and reactions (p = 0.01) after receiving the second dose of the vaccine. On the other hand, the authors observed that those with healthy dietary habits had more IgG titer after the first and second doses of vaccination than those with less healthy dietary habits (p = 0.001). Originality/valueThe results showed that participants with a healthy diet and normal weight status had fewer side effects of the Pfizer-BioNTech COVID-19 vaccine than obese people and those with a less healthy diet.

Perceived stress negatively affects diet quality and life satisfaction during the COVID-19 lockdown period, in Greece. (Special Issue: The relationship between nutrition and COVID-19.)

Purpose: The pandemic of COVID-19 led to considerable challenges with respect to people's health, dietary behavior and satisfaction with life. This study aims to investigate perceived stress levels, in relation to diet quality and life satisfaction in Greek adults, during the COVID-19 lockdown. Design/methodology/approach: This is a cross-sectional study which took place in Greece in the course of the strict lockdown period, in the third COVID-19 wave. A sample of 2,029 adults aged 18 years and above participated in an online survey. The questionnaire consisted of questions on sociodemographic and anthropometric characteristics. The Perceived Stress Scale, the Satisfaction with Life Scale and the Mediterranean Diet Assessment Tool were also used. Findings: Linear regression has shown that women (p < 0.0001), younger individuals (p < 0.0001), obese individuals (p = 0.047), those with lower levels of satisfaction with life (p < 0.0001) and lower adherence to Mediterranean diet (p = 0.0001) were positively associated with higher levels of stress. Originality/value: To the best of the authors' knowledge, this is the first study conducted in Greece aiming at investigating concurrently, levels of perceived stress, with respect to levels of satisfaction with life and diet quality in adults, during the lockdown period of the COVID-19 pandemic.

Long-lasting brain fog is related with severity clusters of symptoms in COVID-19 patients. Background: COVID-19 patients may experience lon-lasting symptoms from weeks to even months. Aim: to evaluate long-term cognitive impairment based on the severity

Background: COVID-19 patients may experience lon-lasting symptoms from weeks to even months. Aim: To evaluate long-term cognitive impairment based on the severity of symptoms of COVID-19 infection in a primary health system setting. Material and methods: From a database of 363 patients, 83 cases aged 47 +or- 15 years, (58% females) were selected from June to August 2020. In patients who survived the virus, 24 infection-related symptoms were collected to create three severity clusters (mild, moderate, and severe). The follow-up time was at least seven months. Comparing the first two clusters with the severe cluster, the existence of brain fog and risk factors (obesity, hypertension, diabetes, chronic lung disease, and hypothyroidism) were analyzed. Results: Thirty-one patients (37%) had persistent symptoms lasting up to 240 days. Fifty-one patients (61%) experienced brain fog. Concentration was affected by symptom severity (odds ratio [OR] 3.63, 95% confidence interval [CI] 1.26-10.46, p = 0.02). Short- or long-term memory loss was not affected. Moreover, symptom severity was related to brain fog (OR 3.16, 95% CI 1.05-9.51, p = 0.04). Patients with persistent symptoms had a concentration impairment associated with severity patterns (OR 24.3, 95% CI 1.73-340.11, p = 0.03). Conclusions: Brain fog is associated with symptom severity in COVID-19 survivors and lasts for more than eight months.

Prevalence of metabolic syndrome criteria among adults post COVID pandemic situation and steps towards prevention

Metabolic Syndrome (MetS) is one among the Non-Communicable Diseases (NCDs) which might occur due to genetic, environmental, physiological and behavioural factors. MetS is increasing alarmingly in the population. Addressing the modifiable factors to reduce the risk is of prime importance. The current study is intended to observe the prevalence of Metabolic Syndrome criteria with respect to its relation to lifestyle factors among subjects post pandemic situation and the MetS incidence to understand how the disease can be prevented and the means to improve the public health. Random sampling method was used to enrol 20-50 year old (male and female) urban adults of Bengaluru into the study. Type-I-diabetics, lactating and pregnant women, post-cardiac surgery/ pre-post-transplant/ covid-19 recovered patients were excluded. Height, weight, Waist-Circumference (WC) and hip-circumference were measured. BMI and Waist-Hip Ratio (WHR) were calculated. Fasting Blood Glucose (FBS), Triglycerides (TG), HDL, Blood Pressure (BP) values were analysed and recorded. Diet recall was captured and calories consumed per day was estimated. The habits of exercise routine, smoking, tobacco chewing and alcohol were observed. IDF (International Diabetes Federation, 2006) criteria was used to categorise MetS. The data was analysed using relevant statistical tools. A total of 1211 adults (females 486 and males 725) were assessed. High WC indicating central obesity was observed in 55%. High FBS was observed in 29%. Hyper-triglyceridemia was more in males (36%) than females (19%). Low HDL was observed in 65% females against 43% males. High BP was observed among 10% in males and 8% in females. Lack of exercise was observed among 81% of the adults. Due to pandemic situation 10.7% stopped doing exercise. Moderate activity in 5.6% and vigorous activity in 2.8% was recorded;68% of the subjects were consuming >2000 calories/day on an average;18.6% were alcoholic. MetS was observed in 10.6% and MetS-2 criteria in 33.4% and MetS-1criteria in 24.5% before pandemic situation and post pandemic there was an increase. MetS was observed in 12.2% and MetS-2criteria in 49.7% and MetS-1criteria in 27.9% post pandemic. The lack of exercise and high-calorie consumption had a significant correlation with altered lipid values and central obesity. High WC had significant relation to High BMI. WHR had very significant correlation with high FBS and TG. Women had significantly high WC compared to men. The alcohol habit had a significant correlation with hypertriglyceridemia in males. Increased calorie consumption had a moderate correlation with raised FBS and WHR. MetS was significantly observed in those who had lack of exercise, high calorie consumption and alcohol habit. Findings suggest that MetS is in rise in 31-50 year age group. Central obesity, dyslipidemia and high FBS were predominant in 31-40 year group. High BP was observed in 45-50 years age group. Identifying and educating the young adults to correct their life style is the need of the hour to reduce increase of MetS in community.

Kadsura japonica fruits exert immunostimulatory and anti-obesity activity in RAW264.7 and 3T3-L1 cells

Under the COVID-19 pandemic, interest in immune enhancement and anti-obesity is increasing. Thus, in this study, we investigated whether Kadsura japonica fruits (KJF) exhibits immunostimulatory activity and anti-obesity activity. KJF increased the production of immunostimulatory factors and phagocytosis in RAW264.7 cells. Inhibition of TLR2 and TLR4 blocked KJF-mediated production of immunostimulatory factors in RAW264.7 cells. In addition, the inhibition of MAPK and PI3 K/AKT signaling pathway reduced KJF-mediated production of immunostimulatory factors, and the activation of MAPK and PI3 K/AKT signaling pathway by KJF suppressed the inhibition of TLR2/4. KJF attenuated the lipid accumulation and the protein expression such as CEBPa, PPARP, perilipin-1, adiponectin, and FABP4 related to the lipid accumulation in 3T3-L1 cells. In addition, KJF inhibited excessive proliferation of 3T3-L1 cells and protein expressions such as beta-catenin and cyclin D1 related to cell growth. These findings indicate that KJF may have immunostimulatory activity and anti-obesity activity.

The effect of body indexes on presence of ocular symptoms in COVID-19 patients

Background: During the COVID-19 pandemic, the presence of ocular symptoms was common in COVID-19 patients, which can cause secondary complications in the treatment of ocular diseases. On the other hand, obesity can cause secondary symptoms in infectious diseases by impairing the function of the immune system, which indicates the relationship between involvement of different tissues and dysfunction of the cellular immune system. The aim of this study was to investigate the relationship between body indexes (i.e., age, height, weight, and BMI) and the presence of ocular symptoms in patients with COVID-19. Methods: In this cross-sectional study (from March 2021 to May 2021), ocular symptoms (including blurred vision, epiphora, photophobia, discharge and exudate, redness, pain, and itching of the eyes) and body indexes (age, height, weight and BMI) were evaluated in 108 patients with COVID-19, who were referred to Ayatollah Rouhani hospital, Babol, Iran. The independent t-test and Kruskal-Wallis statistical tests were used to examine the data relationship in SPSS software. Results: The results showed that the mean body weight in COVID-19 patients with blurred vision was significantly higher than COVID-19 patients without blurred vision (P=0.003, t=-3.056). The mean height of COVID-19 patients with epiphora was significantly lower than the mean height of COVID-19 patients without epiphora (P=0.018, t=2.398). Also, the BMI of COVID-19 patients with epiphora was 30.00 +or-4.07 kg/m2, while the BMI of COVID-19 patients without epiphora was 27.68+or-4.42 kg/m2 (P=0.047, t=0.026). In COVID-19 patients with at least one ocular symptom, height was significantly lower than heigh of COVID-19 patients without any ocular symptoms (P=0.001, t=3.397). Conclusion: Our results indicate the essential role of obesity in the occurrence of eye symptoms in COVID-19 patients. In this study, it was found that blurred vision, epiphora and the presence of at least one eye symptom in COVID-19 patients were significantly associated with the upward trend of BMI (as an index of obesity).

T-fiber, a highland barley fiber-rich powder, alleviates hyperglycemia and improves kidney pathology in Db/db mice

The role of dietary fiber in highland barley in lowering blood lipids has been continuously studied in recent years. However, its effects on diabetes and diabetic nephropathy are rarely studied. Considering that highland barley bran is rich in dietary fiber, the effective use of dietary fiber in highland barley bran can not only alleviate the symptoms of diabetes but also improve the local economy. This article aimed to study the effects of highland barley fiber-rich powder (T-fiber) with a high-quality natural dietary fiber ratio (insoluble fiber/soluble fiber = 3 : 1) on the symptoms of hyperglycemia in a diabetic mouse model. Compared with the model group's blood glucose level (30.80 mmol/L), glucose tolerance (28.57 mmol/L), and glycosylated serum protein (2.43 mmol/L), T-fiber presented significant reductions in blood glucose (23.69 mmol/L), better glucose tolerance (21.32 mmol/L), and glycosylated serum protein (1.78 mmol/L) in the diabetic mouse model. Meanwhile, T-fiber effectively alleviated hepatocellular lesions. In addition, T-fiber not only improved kidney function by reducing the 24-hour urine output (8.25 ml), urine protein levels (11.51 mg), and serum creatinine (13.80 mol/L) but also alleviated renal pathology, including glomerular hypertrophy, mesangial expansion, and fibrosis. The above results proved the ability of T-fiber to reduce blood glucose and alleviate liver and renal function in diabetic mice. Altogether, T-fiber is a capable formula for utilizing highland barley bran dietary fiber, which alleviates diabetes symptoms and endows highland barley with promising value.

Effect of the COVID-19 epidemic on body mass index: findings from a large survey during Wuhan lockdown

This study aimed to explore the effect of the Wuhan lockdown on body mass index (BMI) among Wuhan residents as well as factors including food habits affected and changes in physical activity mediating the association. As a survey of the Wuhan lockdown, a random digit dialing method was used to sample residents aged 18 years and older. A computer-aided telephone interview was applied to survey 11,223 residents in Wuhan City in July 2020. Ordinary least squares (OLS) regression and mediation analysis were used to analyze the influence of the Wuhan lockdown on BMI. Demographic characteristics, lifestyle characteristics, and health status differed statistically significantly between residents living in and those who left Wuhan during the lockdown (mean BMI, 23.05 +or- 0.04 kg/m2 and 22.34 +or- 0.06 kg/m2, respectively). The mean BMI among residents living in Wuhan was 0.42 kg/m2 higher (P < 0.001) than that of residents who left Wuhan during the lockdown, as determined by multivariate OLS regression analysis. Residents living in Wuhan during the lockdown had higher BMI among those aged 18-29 and 30-44 years (P < 0.001), with no difference among those aged 45+ years. The association between living in Wuhan and increased BMI was the strongest among residents who were overweight/obese. The mediation analysis results showed an indirect effect path with living in Wuhan (through decreased physical activity and increasing BMI) and the direct effect of living in Wuhan during the lockdown. The lack of association between living in Wuhan and increased BMI among residents aged 45+ years was due to the indirect influence of living in Wuhan affecting food habits. The findings indicated that the lockdown in Wuhan city increased residents' BMI, especially among those who were young or overweight/obese, partly because of decreased physical activity.

XXI ExpoPPGIm Annual Meeting of the Graduate Program in Immunology, Online, 1-3 September 2021

These proceedings contains 30 articles that covered various topics related to immunology and related fields. The conference papers presented focused on investigating the role of genetics, microbiome, and immunological pathways in disease pathogenesis and treatment. Studies presented at the conference explored the genetic factors associated with obesity in Brazilian children, the role of flavonoids in reprogramming microglia towards a neuroprotective inflammatory profile, the gut microbiome in asthmatic individuals, and the involvement of the MTOR gene and its variants in the severity of COVID-19. Other studies evaluated the immunodiagnostic potential of a protein exclusive to Corynebacterium pseudotuberculosis, genetic markers associated with alcohol dependence and asthma, and the effects of nicotine on glial cells in Parkinson's disease. The conference also presented research on the molecular mechanisms associated with the anti-glioma and immunomodulatory effects of flavonoids, the influence of Trypanosoma cruzi co-infection on the immune response and clinical outcome of patients with cutaneous leishmaniasis, and the association of metalloproteinase gene variants with periodontitis. Furthermore, the papers presented discussed the production of Zika virus singular peptide for the development of serological immunassays, and the role of genetic polymorphisms in the IL1B and IL6 genes in periodontitis. Lastly, the conference included research on the immunological response of broiler chickens fed with diet supplemented with zinc, and the modulatory effects of Agatis flavone on the glial response in an ex vivo model of brain trauma.

Prevention of overweight and obesity at global levels in particular to gastronomic opportunities

With the advent of the Coronavirus and in addition to many factors, stress also appears to be more pronounced in people's lives. In addition, in a life full of constraints, the weight gain is also a function of time spent at home. A stressful life-style and home-spend time affects not only the mental but also physical health. Therefore, a number of chronic diseases have manifested, of which the appearance of abnormal weight gain is increasing. Obesity and overweight once considered the problem of high-income nations but now increasing in low- and middle-income countries, particularly in urban areas. The prevalence of obesity nearly tripled between 1975 and 2016. It is estimated that over 340 million children and adolescents aged 5-19 were overweight or obese in 2016. Obesity rates in adults were found highest in several countries including Mexico, USA, New Zealand and others. In India, the prevalence of obesity is estimated around 40%. The common health consequences of overweight and obesity are cardiovascular disease, diabetes mellitus, osteoarthritis, and cancer. The manuscript, therefore, first summarizes the nutritional suggestions for the prevention and treatment of overweight and obesity. Then it helps in practical implementation by presenting the possibilities offered by gastronomy. In doing so, we present foods that, with their energy and macronutrient content, greatly help to protect against overweight and obesity. Their other useful active ingredient contents are also important in achieving the normal body weight and optimizing energy levels. It is advised that an increased intake of energy-dense foods that are very rich in fats and sugars must be avoided by everyone. Further, the importance of daily regular physical activities should be highlighted in order to prevent overweight and obesity.

WHO report highlights the dangers of obesity

The WHO European Regional Obesity Report 2022 warned of the major health effects of growing obesity on 3 May 2022. In the WHO European Region, over two thirds of adults and one-third of children are overweight or obese. Obesity causes 13 forms of cancer, is a leading cause of death and disability in the region, and requires multidisciplinary treatment. Obesity will replace smoking as the leading cause of avoidable cancer in various countries, according to the analysis. According to the research, obesity should be addressed as a disease, not only a risk factor. The European Region has the second-highest adult obesity rate in the WHO, after the Americas. Overweight and obesity kill more than 1.3 million people worldwide, but these statistics may be low. Overweight and obesity are epidemic in Europe, including males (63%), females (54%). High-income countries have higher rates. The Mediterranean and eastern European countries have the most overweight and obesity. Obese people are more likely to contract COVID-19 and die, and many have had trouble accessing obesity management therapies due to the pandemic. The epidemic has also increased obesity risk factors like sedentary lifestyles and unhealthy food habits, according to preliminary statistics. The WHO recommends prioritizing some immediate policies, such as prohibiting the promotion of unhealthy foods to children, taxing sugar-sweetened beverages, and enhancing the health system's response to obesity management, then creating a practical plan to adopt other interventions later.

Impact of the first COVID-19 lockdown on the lifestyle of elementary school children

COVID-19 lockdown affects people's daily routine and has an impact on their lifestyle. Recent studies documented associations between body weight changes and children's lifestyle during social isolation. Childhood obesity is associated with a higher risk of COVID-19 severity and mortality. Our aim was to assess the effects of lockdown due to the COVID-19 pandemic on children's sleep, screen time, physical activity, and eating habits. 387 parents of five elementary school students between 16 and 26 June 2020 were interviewed through an online questionnaire. Physical activity level decreased (63.8%), sleep (60.9%) and screen (5.64 +or- 3.05 h/day) times and food intake (39.8%) increased. 80.6% of parents reported changes in children's diet: increased consumption of fruits and vegetables (32.4%), breakfast (15.5%), water and sugar-free beverages (17.6%), snacks (40.4%), sugary drinks (9.9%) was observed. Body weight increased in 44.4% of children. The results of the survey conducted under GYERER-Children's Health Program are in line with the international literature findings: body weight change during the quarantine is significantly associated with food intake, snacking, sugary drinks, and we also found association with fruit and vegetable consumption and lack of breakfast. Effective strategies and electronic health interventions are needed to prevent sedentary lifestyle and obesity during lockdown.

Factors associated with mortality in patients with COVID-19 in a public hospital

The objective of the study was to determine the factors associated with hospital mortality in patients with coronavirus disease 2019 (COVID-19). An observational, analytical, case-control study was conducted. Hospitalized patients diagnosed with COVID-19 by serological test and/or molecular test between March and August 2020 were included. The Mann Whitney test was used for statistical analysis and logistic regression was used for the analysis of associated factors. The significance of p-value was < 0.05. A total of 814 patients were included, 556 (68.3%) were men and 246 (30.2%) were older than 60 years. The presence of some comorbidity was evidenced in 29.6% (241 patients);35.8% (292) died. The median age of the deceased was higher compared to the survivors (59 vs. 49;p >0.01). The comorbidities associated with COVID-19 were: obesity (OR= 2.14;95% CI: 1.38-3.32) and arterial hypertension (OR=1.86;95% CI: 1.06- 3.24). Likewise, oxygen saturation levels less than 85% at hospital admission (OR= 3.58;95% CI: 2.82-4.53);age over 60 years (OR=1.96;95% CI: 1.54-2.50) and male gender (OR= 1.64;95% CI: 1.12-2.39) were associated with greater mortality. Finally, the factors associated with hospital mortality were oxygen saturation less than 85% at hospital admission, older than 60 years of age, obesity, and arterial hypertension.

DESIGNING ERGONOMIC POST-COVID-19 SCHOOL FURNITURE

Inappropriately designed classroom furniture that does not take children’s anthropometric measurements into account has a negative effect on children’s musculoskeletal systems. In this study, which kept Covid-19 pandemic policies in mind, students’ static anthropometric dimensions were measured and their descriptive statistics calculated, using mean, standard deviation, percentiles, and statistical tests, including the t-test and one-way ANOVA. A new design for ergonomically oriented classroom furniture for primary school students is proposed that takes into consideration the measured anthropometric dimensions for students’ safety, health, and well-being, and for post-Covid-19 policies. Given the results of the study, school managements must consider the gender and age of students, and take post-Covid-19 policies/protocols into account when procuring classroom furniture. © 2022, South African Institute of Industrial Engineering.

Materials and Methods: Patients with laboratory confirmed COVID-19 were retrospectively screened between March 11 and April 30. Anthropometric measures including standing height and body weight were measured at admission. Body mass index (BMI) was calculated and patients were classified into three groups as BMI< 25, BMI 25-29.99, and BMI30 according to the guidelines for the diagnosis and treatment of obesity in Turkey.

Effects of a gluten-reduced or gluten-free diet for the primary prevention of Cardiovascular disease

Background: Cardiovascular diseases (CVD) are a major cause of disability and the leading cause of death worldwide. To reduce mortality and morbidity, prevention strategies such as following an optimal diet are crucial. In recent years, low-gluten and gluten-free diets have gained strong popularity in the general population. However, study results on the benefits of a gluten-reduced or gluten-free diet are conflicting, and it is unclear whether a gluten-reduced diet has an effect on the primary prevention of CVD. Objectives: To determine the effects of a gluten-reduced or gluten-free diet for the primary prevention of CVD in the general population. Search methods: We systematically searched CENTRAL, MEDLINE, Embase, CINAHL and Web of Science up to June 2021 without language restrictions or restrictions regarding publication status. Additionally, we searched ClinicalTrials.gov for ongoing or unpublished trials and checked reference lists of included studies as well as relevant systematic reviews for additional studies. Selection criteria: We planned to include randomised controlled trials (RCTs) and non-randomised studies of interventions (NRSIs), such as prospective cohort studies, comparing a low-gluten or gluten-free diet or providing advice to decrease gluten consumption with no intervention, diet as usual, or a reference gluten-intake category. The population of interest comprised adults from the general population, including those at increased risk for CVD (primary prevention). We excluded cluster-RCTs, case-control studies, studies focusing on participants with a previous myocardial infarction and/or stroke, participants who have undergone a revascularisation procedure as well as participants with angina or angiographically-defined coronary heart disease, with a confirmed diagnosis of coeliac disease or with type 1 diabetes. Data collection and analysis: Two review authors independently assessed eligibility of studies in a two-step procedure following Cochrane methods. Risk of bias (RoB) was assessed using the Cochrane risk of bias tool (RoB2) and the 'Risk Of Bias In Non-randomised Studies - of Interventions' (ROBINS-I) tool, and the certainty of evidence was rated using the GRADE approach. Main results: One RCT and three NRSIs (with an observational design reporting data on four cohorts: Health Professionals Follow-up Study (HPFS), Nurses' Health Study (NHS-I), NHS-II, UK Biobank) met the inclusion criteria. The RCT was conducted in Italy (60 participants, mean age 41 +or- 12.1 years), two NRSIs (three cohorts, HPFS, NHS-I, NHS II) were conducted across the USA (269,282 health professionals aged 24 to 75 years) and one NRSI (Biobank cohort) was conducted across the UK (159,265 participants aged 49 to 62 years). Two NRSIs reported that the lowest gluten intake ranged between 0.0 g/day and 3.4 g/day and the highest gluten intake between 6.2 g/day and 38.4 g/day. The NRSI reporting data from the UK Biobank referred to a median gluten intake of 8.5 g/day with an interquartile range from 5.1 g/day to 12.4 g/day without providing low-and high-intake categories. Cardiovascular mortality: From a total of 269,282 participants, 3364 (1.3%) died due to cardiovascular events during 26 years of follow-up. Low-certainty evidence may show no association between gluten intake and cardiovascular mortality (adjusted hazard ratio (HR) for low- versus high-gluten intake 1.00, 95% confidence interval (CI) 0.95 to 1.06;2 NRSIs (3 cohorts)). All-cause mortality: From a total of 159,265 participants, 6259 (3.9%) died during 11.1 years of follow-up. Very low-certainty evidence suggested that it is unclear whether gluten intake is associated with all-cause mortality (adjusted HR for low vs high gluten intake 1.00, 95% CI 0.99 to 1.01;1 NRSI (1 cohort)). Myocardial infarction: From a total of 110,017 participants, 4243 (3.9%) participants developed non-fatal myocardial infarction within 26 years. Low-certainty evidence suggested that gluten intake may not be associated with the development of non-fatal myocardial infarction (adjust

Assessment of obesity risk factors in Algerian children during COVID-19 lockdown

COVID-19 is a global pandemic, which has subsequently spread rapidly at all the countries of the world. The first measures taken to limit its spread were the imposition of social distancing and the lockdown. Although these measures are essential, they have important impacts on the behavior of individuals, their health and their lifestyles. The purpose of this study was to know the effect of the confinement on children. We carried out a cross-sectional prospective study on 100 children from the commune of Constantine, Algeria, including 54 boys and 46 girls, aged from 5 to 14 years old. Anthropometric measurements and a validated questionnaire have been completed. Our results showed that lockdown had a negative impact on the physical activity of children (decreased from 79% to 25%). Additionally, daily sitting time in front of TV and computer screens has increased compared to the pre-lockdown period. The frequency of obesity by sex, according to the WHO 2007 z-score references, is more frequent in boys than in girls, whether before or during confinement with a non-significant difference between genders. The high frequency observed of childhood obesity during the lockdown was also associated with eating habits and socio-economic status. This study allowed us to know the negative effects of confinement and its relationship with obesity in children. However, if we really wish to circumscribe the evolution of the phenomenon, it is necessary to act on the various factors identified as each having a share of responsibility in its occurrence.

Low Carb Diet-related Quality of Life (QOL) and health outcomes

To develop a questionnaire to measure the influence of Low Carb Diet Therapy on patients' Quality of Life, and also assess the effect of Low Carb Diet on biochemical, anthropometric and dietary intake parameters reflecting on the evaluation of care, health status and thus the efficacy of online consultation and review methods during COVID-19 Pandemic. Thirty five patients visiting the Diabetologist / Endocrinologist through online methods prescribed Low Carb Diets were administered the QOL questionnaire in Google Form through WhatsApp at online visit to the doctor and the subsequent visit. Other demographic, biochemical, anthropometric parameters, and diet recall were gathered at baseline and the subsequent review. Exploratory Factor Analysis (EFA), Reliability Analysis (RA) using Cronbach's alpha, test-retest reliability were done. The questionnaire assessed 15 aspects or questions in the QOL. Exploratory factor analysis suggested a three-factor solution with eigen values >1 and factor loadings >0.3. The first factor contained 5 reliable items, the second factor contained 4 items, third factor with 6 items (with Cronbach's Alpha= 0.669, 0.884, 0.775 respectively) As hypothesized, the QOL was better among patients following Low Carb Diets with higher levels of happiness, more satisfaction with their life and health and also, their biochemical, anthropometric and intake improved. These findings indicate the efficacy of the Low Carb Diet education on QOL and the influence on biochemical, anthropometric and dietary intake parameters was noted. This also shows the efficacy of online consultation and review methods during Pandemic.
