In 2019, a new type of infectious disease of the respiratory tract broke out caused by a new coronavirus that was genetically very similar to the SARS virus. The disease, which is caused by the Covid-19 virus, has spread rapidly around the world and is currently affecting many countries around the world (1). This epidemic has also caused physical health concerns; it also causes a number of psychological illnesses, including stress and anxiety (3), which can affect the quality of life of patients and even the general public. The part of the population affected by COVID-19 is children. Children of all ages are sensitive to COVID-19 and there is no significant sex difference between boys and girls. Although the clinical manifestations of COVID-19 cases in children are generally lower than in adult patients, young children, especially infants, were vulnerable to infection (10). Children are part of the population who spend most of their time in Covid-19 due to the protection and prevention of Covid-19 disease, as well as the change in education style towards virtual and distance education, as well as the closure of schools in some areas. They spend time at home. Due to the restrictions on the presence of children outdoors, such as schools and training centers and sports clubs, and on the other hand, changing the educational style and turning the educational system to using distance education methods, students also use From electronic devices such as phones, tablets and computers, as well as watching educational programs by radio and television, and the combination of these factors can promote sedentary lifestyle in children. However, due to changes in educational methods and parentschr('39') desire to control and protect children more, their presence in group activities and outdoors has decreased, which causes more inactivity of these children, which can cause some complications in this population.
Methods
The present study is a review study based on information collected from Internet sources such as Google Scholar and PubMed using the keywords COVID-19; Heath; Children; sedentary; Physical Fitness was performed.
Results
Recent data from the China Centers for Disease Control and Prevention show that out of 44672 COVID-19-approved cases since February 112020416 (0.9%) are in the age range of 0-10 years and 514 people (1.2%) were in the age range of 10-19 years (9). Children of all ages are sensitive to COVID-19 and there is no significant sex difference between boys and girls. Most epidemiologists agree that many of the successes in controlling the virus in China and elsewhere have been due to the swift action taken by the authorities to impose quarantine on most people. Although a quarantine period is the best option and recommendation for stopping rapidly spreading infections, it may have side effects on other aspects of health in patients with health-related risk factors (13). Children are part of the population who spend most of their time in Covid-19 due to the protection and prevention of Covid-19 disease, as well as the change in education style towards virtual and distance education, as well as the closure of schools in some areas. They spend time at home. Due to the restrictions on the presence of children outdoors, such as schools and training centers and sports clubs; and also, changing the educational style and turning the educational system to using distance education methods also leads students to use electronic devices such as phones, tablets and computers, as well as watching educational programs by radio and television. These factors can promote sedentary lifestyle in children. Data from 27 countries show a decline in childrenchr('39')s global performance in the 20-meter shuttle test over the past few decades (17); which shows the role of sedentary behaviors in reducing the physical fitness of children around the world. Regular physical activity has been accepted as an effective preventive measure for various types of health risk factors in all different age, gender, ethnic and socio-economic groups (21, 22). However, in all age groups, the level of physical activity is low (21) and the rate of obesity is still increasing (21, 23). Given that the Covid-19 epidemic increases sedentary behaviors, especially in the pediatric population, it can have negative and irreversible effects on their health, but given that the epidemic has recently spread. But so far, most researches have examined the descriptive and analytical results regarding the incidence and pathology of this disease and due to the short life span of this disease so far regarding the chronic complications of this disease such as chronic diseases and long-term complications due to light change. Life has not been studied on the level of health of different populations.
Conclusion
Due to the prevalence of Covid-19 virus and preventive measures against the spread of the disease, it may lead to increased sedentary behaviors and decreased physical activity and the presence of students outside the home. On the other hand, it has been found that spending time outdoors and playing increases metabolism as well as weight control in children (31, 32) and of course reducing it can lead to weight gain and obesity and diseases related to childhood obesity and Affect the level of health of children. On the other hand, sedentary and obese behaviors can reduce physical fitness and also impair motor development in children, which in addition to motor complications cause secondary problems such as metabolic diseases and cardiovascular diseases at older ages. Given that increased physical activity and play can improve health-related problems in children, there is a need for preventive programs to prevent sedentary lifestyle and increase mobility in this age population, which can have positive effects on childrenchr('39')s health. . Due to the problems associated with Covid-19 disease and the effects of behavioral change caused by this disease on physical fitness and health of children, no research has been done so far and our knowledge about the effects of sedentary behaviors due to lifestyle changes is limited. The amount of physical activity, the type of physical activity, the intensity and volume of exercises and how to implement physical education programs are limited according to modern teaching methods, and more research is needed in this regard.
