The long-term effects of COVID-19 is becoming increasingly documented in adults. Symptoms such as fatigue, headache and depression have all been reported, however data on the possible long-term effects of COVID-19 in children is scarce. The aim of this systematic review and case report was to describe the long-term effects of COVID-19 in five children and support this with other reports in the literature. The results showed that of the five case reports of long COVID, four were girls aged 9-15 years. All subjects reported symptoms lasting between 6-8 months. Most common symptoms were fatigue, difficulty breathing and heart issues. The systematic literature review did not find any publications which documented long COVID in children. It was concluded that children may experience long COVID symptoms and girls may be more susceptible. This study could be used by healthcare professionals to understand that children may also be affected by long COVID and that patients should be monitored for symptoms for at least 6-8 months.
Abstract
AIM: Persistent symptoms in adults after COVID-19 are emerging and the term long COVID is increasingly appearing in the literature. However, paediatric data are scarce. METHODS This paper contains a case report of five Swedish children and the long-term symptoms reported by their parents. It also includes a systematic literature review of the MEDLINE, EMBASE and Web of Science databases and the medRxiv/bioRxiv pre-print servers up to 2 November 2020. RESULTS The five children with potential long COVID had a median age of 12 years (range 9-15) and four were girls. They had symptoms for 6-8 months after their clinical diagnoses of COVID-19. None were hospitalised at diagnosis, but one was later admitted for peri-myocarditis. All five children had fatigue, dyspnoea, heart palpitations or chest pain, and four had headaches, difficulties concentrating, muscle weakness, dizziness and sore throats. Some had improved after 6-8 months, but they all suffered from fatigue and none had fully returned to school. The systematic review identified 179 publications and 19 of these were deemed relevant and read in detail. None contained any information on long COVID in children. CONCLUSION Children may experience similar long COVID symptoms to adults and females may be more affected.

Plain language summary
Obesity in children is increasing and low rates of activity and poor eating habits appear to be at the heart of the problem. New digital technologies and interventions to encourage physical activity are becoming popular and have been assessed in previous reviews, but none of these have focused on children. This systematic review aimed to determine the effectiveness of new digital technologies being used to encourage physical activity in primary school aged children. The results showed that using new digital technologies to improve eating habits and levels of physical activity were of benefit to primary school aged children, however this had limited effect on body mass index. It was concluded that the use of digital technologies in school aged children may be of benefit to health through the prevention of obesity. This study could be used by healthcare professionals to understand that obesity in children is increasing and the use of digital technology to improve physical activity and eating habits may be an effective strategy to combat this.
Abstract
Early acquisition of healthy lifestyle habits is crucial for good adult health. For this reason, the primary stage of education is a critical period to implement educational policies in this regard. The aim of this review is to compile the published evidence regarding school interventions at the primary stage aimed at preventing obesity, and which integrate as part of their action plan two features: an improvement in knowledge or nutrition habits and the promotion of physical activity (PA), and the use of new information and communications technologies (ICT) to do this. The method used for this review is the searching of different databases for publications that include these criteria. The results show beneficial effects of such interventions in improved eating habits and increased PA. The effect on BMI is limited, and the use of ICT can be of help at a motivational level for the maintenance and fulfilment of the health objectives. However, studies of this type in elementary school are very limited, so it would be necessary to continue researching on this line. In conclusion, this review demonstrates the suitability of carrying out mixed interventions (improved nutrition and PA) together with the use of new technologies to improve health and prevent obesity at an early age.

Plain language summary
Iron deficiency is the most common vitamin or mineral deficiency worldwide and is particularly common among pregnant women, infants and young children due to high iron demands during periods of rapid growth. Iron plays an important role in the development of the brain, and animal studies suggest that getting enough iron in pregnancy and early childhood is particularly important. The aims of this systematic review were to (i) investigate the relationship between iron status and brain development and (ii) assess whether this relationship differs according to age or type of development (‘domain’). The researchers looked for studies on iron deficiency or iron supplementation in pregnancy and up to 4 years of age. 26 observational studies and 28 intervention studies were included in the review. There was no clear relationship between iron status and developmental outcomes across any of the ages or domains included. Many of the studies were of low quality and there was a wide variation in study design, along with a lack of research on pregnancy and early infancy. The researchers concluded that evidence for the impact of iron deficiency or iron supplementation on early development is inconsistent. Further high-quality research is needed, particularly within pregnancy and early infancy, which has previously been neglected.
Abstract
One-third of children falter in cognitive development by pre-school age. Iron plays an important role in many neurodevelopmental processes, and animal studies suggest that iron sufficiency in pregnancy and infancy is particularly important for neurodevelopment. However, it is not clear whether iron deficiency directly impacts developmental outcomes, and, if so, whether impact differs by timing of exposure or developmental domain. We searched four databases for studies on iron deficiency or iron supplementation in pregnancy, or at 0-6 months, 6-24 months, or 2-4 years of age. All studies included neurodevelopmental assessments in infants or children up to 4 years old. We then qualitatively synthesized the literature. There was no clear relationship between iron status and developmental outcomes across any of the time windows or domains included. We identified a large quantity of low-quality studies, significant heterogeneity in study design and a lack of research focused on pregnancy and early infancy. In summary, despite good mechanistic evidence for the role of iron in brain development, evidence for the impact of iron deficiency or iron supplementation on early development is inconsistent. Further high-quality research is needed, particularly within pregnancy and early infancy, which has previously been neglected.

Plain language summary
Metabolic Syndrome is the term used to group a cluster of health concerns including overweight, obesity, hypertension, elevated cholesterol, blood glucose intolerance and insulin resistance which together can contribute to the development of Type II Diabetes and Cardiovascular Disease. Diagnosis is usually given if a patient has three or more of these conditions however the diagnosis in children and adolescents is often inconsistent, and so guidelines for therapeutic strategies for metabolic syndrome also vary greatly. This review looked at 9 studies of children aged up to 19 years old, all diagnosed with metabolic syndrome, and given dietary, physical, psychological, and pharmacological interventions, to try and understand what the best clinical approach might be. It was found that a balanced diet combined with aerobic and resistance exercise helped to significantly reduce body mass, more so than the trials which included treatment with Metformin. A balance diet included calorie restriction and carbohydrate reduction, carefully planned around the daily exercise program of 2-3 resistance sessions each week and frequent cardio sessions of differing intensity and duration. They concluded that a minimum of 6 months was needed to reach optimal weight loss and body fat loss. Overall, the findings of this study support diet and physical exercise as beneficial clinical interventions, whilst the use of medication is still unclear.
Abstract
OBJECTIVE To record which interventions produce the greatest variations in body composition in patients ≤19 years old with metabolic syndrome (MS). METHOD search dates between 2005 and 2017 in peer reviewed journals, following the PRISMA method (Preferred Reporting Items for Systematic reviews and Meta-Analyses). The selection criteria were: diagnostic for MS or at least a criterion for diagnosis; randomized clinical trials, ≤19 years of age; intervention programs that use diet and/or exercise as a tool (interventions showing an interest in body composition). RESULTS 1781 clinical trials were identified under these criteria but only 0.51% were included. The most frequent characteristics of the selected clinical trials were that they used multidisciplinary interventions and were carried out in America. The most utilized parameters were BMI (body mass index) in kg/m² and BW (body weight) in kg. CONCLUSIONS Most of the clinical trials included had been diagnosed through at least 2 diagnostic criteria for MS. Multidisciplinary interventions obtained greater changes in body composition in patients with MS. This change was especially prevalent in the combinations of dietary interventions and physical exercise. It is proposed to follow the guidelines proposed for patients who are overweight, obese, or have diabetes type 2, and extrapolate these strategies as recommendations for future clinical trials designed for patients with MS.
