Chronotype reflects an individual’s preferred time of the day for an activity/rest cycle and individuals can be classified as a morning, intermediate, or evening type. A growing number of studies have examined the relationship between chronotype and general health. This review aimed to map current evidence of the association between chronotype and dietary intake among the adult population. A systematic search was conducted across five databases: EBSCO Host, Medline & Ovid, Pubmed, Scopus, and The Cochrane Library. The inclusion criteria were adult subjects (more than 18 years old), and included an assessment of (i) chronotype, (ii) dietary behaviour/nutrient intake/food group intake, and (iii) an analysis of the association between chronotype and dietary behaviour/nutrient intake/food group intake. A total of 36 studies were included in the review. This review incorporated studies from various study designs, however, the majority of these studies were based on a cross-sectional design (n = 29). Dietary outcomes were categorized into three main groups, namely dietary behaviour, nutrient intake, and specific food group intake. This scoping review demonstrates that evening-type individuals are mostly engaged with unhealthy dietary habits related to obesity and were thus hampered in the case of weight loss interventions. Hence, this review has identified several dietary aspects that can be addressed in the development of a personalised chrono-nutrition weight loss intervention.

AbstractObjectiveTo assess how well supermarket sales data from a major supermarket chain can reflect on regional differences in dietary behaviour by comparing the sales data with the results provided by the annual health behaviour surveys.DesignCross-sectional observational study.SettingThe study was carried out in six Finnish cities situated in different parts of Finland. For the study supermarket sales data of milk, sour milk, fats and oils for 1 month, September 1997, were obtained from eight supermarkets. Proportional sales of different types of dairy products were calculated as well as mean salt and fat per cent and the proportion of saturated fat to total fat. The health behaviour surveys from spring 1995, 1996 and 1997 provided information about dietary habits of the adult population in the cities. The reported use of dairy products was compared with the percentage sales.ResultsThe proportional sales of dairy products varied between the cities. In Pori in western Finland the sale of milk fat was highest in all food groups. In Oulu, northern Finland, the sale of non-fat milk was high. In the capital region the sale of oil was highest. Regional differences could also be seen in the survey data. The similarity between the two different datasets was high.ConclusionsThe use of supermarket sales data for assessing regional differences in health behaviour is feasible. The challenge will be to get supermarket managers willing to provide sales data on a routine basis for monitoring and research.

AbstractObjectivesTo determine the differences in macronutrient and food group contribution to total food and energy intakes between Estonian and Swedish under-, normal- and overweight schoolchildren, and to estimate the association between diet and body mass index (BMI).DesignCross-sectional comparison between Estonian and Swedish children and adolescents of different BMI groups.SettingTwenty-five schools from one region in Estonia and 42 in two regions of central Sweden.SubjectsIn total 2308 participants (1176 from Estonia and 1132 from Sweden), including 1141 children with a mean age of 9.6 ± 0.5 years and 1167 adolescents with a mean age of 15.5 ± 0.6 years.ResultsOverweight was more prevalent among younger girls in Sweden (17.0 vs. 8.9%) and underweight among girls of both age groups in Estonia (7.9 vs. 3.5% in younger and 10.5 vs. 5.1% in older age group of girls). Compared with that of normal- and underweight peers, the diet of overweight Estonian children contained more energy as fat (36.8 vs. 31.7%) but less as carbohydrates, and they consumed more milk and meat products. Absolute BMI of Estonian participants was associated positively with energy consumption from eggs and negatively with energy consumption from sweets and sugar. Swedish overweight adolescents tended to consume more energy from protein and milk products. Risk of being overweight was positively associated with total energy intake and energy from fish or meat products. In both countries the association of overweight and biological factors (pubertal maturation, parental BMI) was stronger than with diet.ConclusionThe finding that differences in dietary intake between under-, normal- and overweight schoolchildren are country-specific suggests that local dietary habits should be considered in intervention projects addressing overweight.

Abstract Background The COVID-19 pandemic has forced governments around the world to impose strict hygiene and national lockdown measures, which in turn has changed the dietary and lifestyle habits of the world’s population. Thus, the aim of this study is to evaluate whether dietary and physical activity behaviors of Saudi Arabia’s adult population changed during the COVID-19 quarantine. Methods An electronic questionnaire which assessed changes in body weight, dietary habits, and physical activity of Saudi Arabia’s adult population (n = 2255) during the COVID-19 quarantine was distributed on social media between June and July 2020. To test the differences between changes in dietary and physical activity behaviors in relation to changes in body weight a Chi-square test was used. Results Over 40 and 45% of participants reported eating and snacking more, respectively, which led to weight gain in around 28%. Most participants reported that they consumed home-cooked (73%) and healthy meals (47%), while only 7% reported that they consumed foods from restaurants. Feelings of boredom and emptiness (44%) and the availability of time for preparing meals (40%) were the main reasons for changing dietary habits. Honey (43%) and vitamin C (50%) were the most consumed immune-boosting food and dietary supplement, respectively. COVID-19 also had a negative impact on physical activity, lowering the practice in 52% subjects, which was associated with significant weight gain (p < 0.001). Conclusion Assessing the changes to the population’s dietary habits and physical activity during the lockdown will help predict the outcome of the population’s future health and wellbeing after the pandemic.

Objectives. To map the current evidence on surgical antibiotic prophylaxis (SAP) administration and identify knowledge gaps in the literature available in this field. Methods. The PubMed, Cochrane Library, Epistemonikos, and Health Systems Evidence databases were searched from January 2015 to March 2020 for systematic reviews published in English, French, Portuguese, and Spanish. Results. Eighty-three systematic reviews were included, the quality of the reviews was assessed using AMSTAR 2, and data were extracted for all primary outcomes. Perioperative antibiotic administration, the use of first generation cephalosporins, and surgical site infection (SSI) were the most commonly reported for timing of antibiotic administration, drug class, and primary outcome, respectively. Findings showed that, overall, SAP may reduce SSIs compared with a placebo or with no SAP. Results suggested that intraoperative SAP may lower SSI, while postoperative SAP did not show a statistically significant difference. Conclusions. Findings have confirmed the role of SAP in reducing postoperative SSI across various surgeries and do not support the use of antibiotics after surgery to prevent infections. The findings of this scoping review have enhanced the evidence base that can inform decisions regarding the development of global guidelines for the prevention of SSI. However, high-quality systematic reviews and research reflecting diverse populations and settings are needed.

Abstract Background and Aims Risk factors for chronic kidney disease (CKD) such as type 2 diabetes mellitus (DM2), high blood pressure (HBP) and obesity are strongly related to negative lifestyle and nutritional habits. The aim of this study was to estimate the proportion of patients with and without risk factors for CKD who meet recommendations for food consumption. Method Cross-sectional study. A qualitative food frequency questionnaire (FFQ) was applied. Consumption of each food group was classified as adequate or inadequate based on dietary guidelines (DASH and ENSANUT Mexican Guidelines). Sociodemographic, biochemical and clinical variables were measured. DM2, HBP and obesity were defined as risk factors. Results 744 adults were evaluated, age 51±16 y, 68% women, 59% without risk factors, 7% DM2, 17% HBP, 8% DM2+HBP, and 18% obesity. Glomerular filtration rate was 99 (89-100) mL/min/1.73m2. Differences in FFQ between groups were found in relation to consumption of legumes, fast food, sugar, sweets and desserts (p&lt;0.05). Figure A shows the frequency of consumption of healthy and B, unhealthy foods. Conclusion In general, subjects in this sample had negative dietary habits, with &lt;50% consuming healthy food and &gt;50% consuming unhealthy food. Subjects without risk factors for CKD displayed a similar pattern of food consumption than those with risk factors, with only a significantly lower legumes intake than patients with HBP, and higher intake of sweets and desserts, sugar, and fast food compared to patients with DM2+HBP. It is necessary to implement strategies to prevent the long-term development of CKD in groups with poor adherence to healthy food consumption recommendations.

Abstract Background and aims The concept of bad posture being a dominant driver of pain is commonly held belief in the society. This may explain the significant attention supportive clothing such as posture-correcting shirts has recently gained in Scandinavia and the USA. The aim of this scoping review was to present an overview and synthesis of the available evidence for the use of posture-correcting shirts aimed at reducing pain or postural discomfort and optimising function/posture. Methods A systematic search was conducted for literature investigating the effect of posture-correcting shirts on musculoskeletal pain or function. PubMed, Embase, CINAHL, PEDro and the Cochrane Library were searched for relevant literature. Results of the searches were evaluated by two independent reviewers in three separate steps based on title, abstract and full text. For data synthesis, the population, intervention, comparator and outcome were extracted. The quality of the literature was evaluated using the Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies and the risk of bias was assessed using the Risk Of Bias In Non-randomized Studies – of Interventions (ROBINS-I) assessment tool or the RoB 2.0 tool for individually randomized, parallel group trials. The overall confidence in the literature was determined using the Grading of Recommendations Assessment, Development and Evaluation (GRADE). Results A total of 136 articles were identified and six of these were included in the review. These studies were heterogeneous with regards to aims, outcomes and methods, presenting contrasting results. The overall findings were that posture-correcting shirts change posture and subjectively have a positive effect on discomfort, energy levels and productivity. The quality of the included literature was poor to fair with only one study being of good quality. The risk of bias was serious or critical for the included studies. Overall, this resulted in very low confidence in available evidence. An important limitation of all studies was that they were conducted in pain-free individuals. Conclusions The contrasting findings and the low quality of current literature, questions the intended effect of posture-correcting shirts and whether the changes it creates are in fact useful for clinical practice. Moreover, the findings are contrasted by the available evidence regarding posture and pain with a particular focus on whether this management strategy may have a detrimental effect on people living with musculoskeletal pain. A major limitation to the existing literature on the effect of posture-correcting shirts is that no studies have investigated their effect in clinical populations. Implications Based on the available literature and the major limitation of no studies investigating clinical populations, there is no good quality evidence to support recommendation of posture-correcting shirts as a management strategy for musculoskeletal pain. Promotion of this product may reinforce the inaccurate and unhelpful message that poor posture leads to pain. The efficacy of such garments should be tested in clinical populations and not only in pain-free individuals, to assess whether there is any meaningful benefit of this management approach. Until then, the use of posture-correcting shirts for musculoskeletal pain is not supported by current evidence.

AbstractObjective:The way in which nutrition knowledge transforms into dietary behaviour and nutrient intake may vary among populations. Therefore, the goal of the study was to examine whether nutrition knowledge is associated with nutritional intake in middle-aged men who are at major risk of cardiovascular disease.Design:Cross-sectional population study aimed at comparing the response to a nutrition quiz with food habits and nutrient intake determined by a 3-day food record.Setting:Men of the Urban Community of Lille (France) examined at home.Subjects:361 men aged 45–64 y, randomly selected from the electoral rolls.Results:Subjects were separated in a high-score (n = 59) and a low-score (n = 41) group according to their responses to the nutrition quiz. Subjects in the high-score group had better educational and higher income levels than those from the low-score group. Multivariate analysis, adjusting on educational and socio-economic levels and other confounding variables – such as age, body mass index, cigarette smoking, physical activity and energy intake underreporting – showed that subjects in the high-score group were more often consumers of olive oil (36 vs. 12%; p = 0.06), cheese (85 vs. 76%; p<0.01) or cereals (27 vs. 15%; p<0.04) and less often consumers of sunflower oil (51 vs. 68%; p<0.02) or dry vegetables (12 vs. 22%; p<0.05) than those in the low-score group. Subjects in the high-score group had lower intakes of fat (89±24 vs. 104±38 g/d; p = 0.04) and especially of monounsaturated fat of animal origin (23±9 vs. 29±13 g/d; p = 0.01) than individuals in the low-score group.Conclusion:Nutrition quiz score is associated with specific patterns of food choices and nutrient intake suggesting that nutrition knowledge influences dietary behaviour in middle-aged men from Northern France.

IntroductionThe atypical antipsychotic clozapine has shown superior efficacy compared with other antipsychotics and is the gold standard for treating otherwise treatment resistant schizophrenia. However, multiple studies have found that clozapine is underutilised in most parts of the world. A few reviews of literature addressing barriers to clozapine prescribing have been conducted. While there is some variation in the literature included in these reviews, a common feature of the studies included is that they primarily focus on clinical staff’s attitudes and perceived barriers for prescribing. Studies of patient perspectives are only sparsely included. A preliminary literature search revealed though, that additional literature on the subject exists, including literature on patient perspectives. It is therefore difficult to conclude if the formerly synthesised literature is representative of current evidence or if the topic has been adequately investigated to inform clinical practice. A scoping review is warranted in order to map and synthesise primary literature on patients’ and psychiatrists’ perspectives on clozapine treatment, and to identify gaps for future research.Methods and analysisThe electronic databases Cochrane Library, CINAHL, Web of Science, Psychinfo, MEDLINE and EMBASE will be searched for relevant publications, supplied with searches of Google scholar, The Networked Digital Library of Theses and Dissertations and OpenGrey. Citation tracking of selected studies will furthermore be undertaken. Two researchers will independently screen and extract data. Data will be collated to provide a descriptive summary of the literature, along with a qualitative content analysis of key findings. Identified gaps in research will be accompanied by recommendations for future investigations.Ethics and disseminationFindings will be disseminated through a peer-reviewed journal and conference presentations. The scoping review does not require ethics approval.

Background: The global outbreak of COVID-19, for which there is few evidence-based effective vaccines or treatments available yet, has led to many attempts to find alternative options. Objective: This study aimed to compare the general dietary habits and lifestyle between before and during COVID-19 among the Saudi adult population in Riyadh Methods: It was a cross-sectional study, targeting the Riyadh population, from 16 May 2020 to 16 June 2020. The study comprised a structured questionnaire design that inquired demographic information examples include:(age, gender, place of residence, and health status); dietary habits information (daily intake of certain foods, food frequency, number of meals/days, and number of times drinking the tea and coffee); lifestyle habits information (physical activity, sleep quality, time that spend using the internet, social media and electronic devices for fun daily and stresses) using Google form. A total of 1,193 participants have been included in the study aged over 18 years. Results: During the COVID-19 period, a significant increase in the number of meals eaten daily, the number of times of fruits and vegetable intake, the number of sweets, cakes, and biscuits, the number of hours of sleep per day, the time using the internet and social media were observed more than at in the before COVID-19 pandemic period. However, the number of running exercise or physical activity were significantly reduced. Conclusion: In this study, the dietary and lifestyle habits have changed among the Saudis during the COVID-19 period. Future large-scale similar studies should be undertaken to confirm the results of the study.

Introduction: Despite more than one year passed since the first cases of SARS-CoV-2 were reported, there is still no consensus on the definition and clinical management of post-acute-COVID-19. The condition has heterogeneously been named as Chronic COVID syndrome, Post COVID-19 Syndrome, post-acute sequela of SARS-CoV-2 (PASC), and the more familiar long COVID. Method: In order to capture all relevant published studies, we undertook a multi-step search with no language restriction. The following four-step search strategy was utilized: First, a preliminary (limited) search was conducted on January 20, 2021, in Google Scholar and PubMed to identify the appropriate keywords. Then, on January 30, 2021, we adopted a search strategy of electronic databases from Cochrane Library, PsycINFO, PubMed, Embase, Scopus, and Web of sciences, using those keywords. Then, after duplicate removal, we screened all titles, abstracts, and full texts. This resulted in 66 eligible studies. Subsequently, after a forward and backward search of their references and citations an additional 54 publications were found, resulting in a total of 120 publications that formed the basis of the present analysis. The titles, abstracts, and full-texts of non-English articles were translated using Google Translate for further evaluation. We conducted our scoping review based on the PRISMA-ScR Checklist.Results: We found only one randomized clinical trial in our search. Of the 67 original studies, 22 were cohort and 28 were cross-sectional studies totaling 74.6% of the original studies. Of the total of 120 publications, 59 (49.1%) focused on signs and symptoms, 28 (23.3%) were focused on management, and 13 (10.8%) focused on pathophysiology. Ten (9%) publications focused on imaging studies. Ninety-one percent of the original investigations came from high and upper-middle-income countries, highlighting the scarcity of reports originating from low-income and lower-middle-income countries.Conclusion: The predominant symptoms among those with the so-called &ldquo;Long COVID&rdquo; were: fatigue, breathlessness, arthralgia, sleep difficulties, and chest pain. Recent reports also point to the risk of long-term sequela with cutaneous, respiratory, cardiovascular, musculoskeletal, mental health, neurologic, and renal involvement in those who survive the acute phase of the illness. The ambiguity and controversies in its definition have impaired proper recognition and management of those requiring additional support following the resolution of the acute phase of this infection. This has resulted in long-standing distress for the patients and their families. Our findings highlight the need for a multidisciplinary approach, support, and rehabilitation for these patients in terms of long-term mental and physical health.
