## Abstract

The purpose of this study is to investigate the relationship between the various factors that affect children’s physical health. By analyzing the physical examination results of 1,000 children who had health examinations in the hospital from June 2019 to June 2021 in a SQL database, we were able to determine the factors influencing children’s physical health. Additionally, a method for assessing the physical health risks being faced by children is developed. To increase the evaluation’s effectiveness, a new type of physical health risk assessment system for children is being developed on the basis of the original physical health risk assessment system for children. The system hardware component optimizes the primary control chip and minimizes the system circuit to the smallest possible size. Simultaneously, a model for risk assessment of physical health is developed in children and a risk quantification procedure is implemented. The membership degree of the risk value is calculated using the fundamental concept of fuzzy logic, and the evaluation result is incorporated into this step of the computation to generate an accurate evaluation level. To date, no system for assessing physical health risks in children has been developed. We discovered while building the system test that the query accuracy of this system’s evaluation level can reach up to 96%, the detection time is reduced to a minimum of 5 seconds, and the usage effect is improved.

## 1. Introduction

Children are humanity’s future, and their development is critical to a country’s economic and social development, and to the advancement of civilization. In 2020, China will have 240 million children aged 0–15 years, accounting for 18% of the total population. According to a white paper on the status of pediatric resources in China and the 2020 China Health and Family Planning Statistical Yearbook, China has an overall pediatric physician population of 97,000, with a shortage of more than 200,000 pediatricians. By 2020, China’s pediatric outpatient and emergency department visits will reach 500 million, and pediatricians’ workload will be 2.5 times that of other physicians. On an average day, a pediatrician sees 2,000 children. As a result of population mobility, the uneven development of children in urban and rural areas, the poor health of children in impoverished areas, and the difficulties associated with monitoring children’s healthcare have become major issues in children’s healthcare. With the widespread use of the internet, big data, cloud computing, and the internet of things, the question of how to use big data to improve children’s health has become a hot topic of debate in both academic and industrial circles in our country. The General Office of the State Council issued a set of “Guiding Opinions on Promoting and Regulating the Application and Development of Big Data in Health and Medical Care” in 2016, calling for vigorously promoting the interconnection and integration of government health and medical information systems, and the open sharing of public health and medical data, eliminating information silos, and actively promoting health and medical care on a large scale. The internet + healthcare enables the development of data security standards and novel applications, and the exploration of novel service models, the cultivation of novel formats, and the development of novel formats. In the United States, there are very few large-scale studies on children’s health [1–8]. Industrialized countries such as the United States, the United Kingdom, Singapore, and the European Union have also developed big data strategic plans with the goal of resolving long-standing problems or identifying new value opportunities.Medical, informatics, computer science, and systems science are just a few of the fields that are involved in big data research in children’s health. Growth and development monitoring, health records, medical records, lifestyle habits, genomic sequencing, and wearable devices are all examples of big data in children’s health. The importance of big data in medical care is depicted in Figure1 as a flowchart.Figure 1
Big data in medical care.Not only does constitution refer to one’s level of physical development but also to the adaptability of one’s physiology, psychology, physical fitness, and exercise, and other facets of one’s personality. It is a broad and stable characteristic that is inherited from both hereditary and acquired origins. The physical health of young children has long been a topic of discussion throughout the world, particularly in the United States, in recent years. Children are a country’s future and hope for development. As a result, the physical health of children is inextricably linked to the country’s long-term growth, which defines the country’s future prosperity and development and is critical to human civilization’s advancement. Recent research on the physical health of young children, both domestically and internationally, has primarily focused on the current state of physical fitness and physical health intervention. As a result, the first section of this study examines the application of big data to pediatric health. A second step involved administering a questionnaire to the parents of the 1,000 healthy children who were randomly selected as research subjects from the SQL database [9–11]. The factors affecting the physical health of young children were investigated using univariate and regression analyses with the goal of providing reliable and accurate reference data to the state and relevant departments for the purpose of developing applicable development plans. Finally, this research establishes a system for assessing children’s physical health risks.


## 2. The Application of Big Data in Children’s Health

### 2.1. Growth

Infancy and childhood are a time of rapid growth and development, and the development of height, body mass, waist circumference, and head circumference is directly related to the overall health and well-being of children. Children’s health information can be collected in real time and stored in the cloud via wearable devices (such as pedometers, weight scales, sleep monitoring watches, and sports bracelets). These data can be used to make critical comparisons when assessing the growth and development of youngsters. Continuous big data on children’s health can be used to assess the growth and development status of children of different genders and ages, screen for children who have deviated growth and development, and provide targeted assessment, diagnosis, and intervention recommendations in order to promote children’s growth, development, and physical health, among other things [12, 13].


### 2.2. Dietary Supplements

Children’s growth and development are largely dependent on their nutritional status. Children consume a large number of meals that are diverse in kind. The dietary survey of children is carried out using the immediate image technique dietary survey technology, and it is possible to gather information on the intake of various nutrients by children. Through the collection and analysis of large amounts of data on the nutritional status and needs of children of various ages, it will be possible to assess their dietary behavior and nutritional status in order to provide targeted feeding and dietary guidance, health education, and nutritional disease prevention technology to them. Using big data technology, we can monitor and follow up on children who are malnourished or suffering from anemia, obesity, or other nutritional diseases and conduct dietary nutrition evaluations, feeding guidance, dietary prescription formulation, physical exercise plans and healthy living habits, and other comprehensive interventions for these children [14–18].


### 2.3. The Study of Psychology

Comparatively speaking, children’s psychological development is a more challenging indication to assess than physical health. Movement, language, cognition, social behavior, temperament, emotion, and sexuality are all facets of a child’s psychological development that are particularly noticeable. The psychological behavior of children grows and evolves throughout time as they grow older. When compared to physical health, these markers are more abstract and ambiguous; therefore, it is difficult to direct monitoring in this area. Despite this, researchers, both domestically and internationally, have studied the application of big data in psychology, with a particular emphasis on nonmedical health psychology disciplines such as emotion and well-being. The internet has permeated every area of people’s lives, and network traces will generate huge amounts of data that can be utilized to investigate the psychological elements that influence internet users’ use of the internet. This research aims to conduct longitudinal tracking of psychological and behavioral big data of children and adolescents in the process of growth, in order to investigate the development trajectory and influencing factors of adolescents’ self-awareness, and to assist families in adapting their parenting styles over time in accordance with the psychological characteristics of their children [19, 20]. While the majority of the time, the diagnosis of autism in children is based on the children’s behavior, there is significant variation in autism among different children. It is beneficial for the diagnosis and individualized treatment of autism to collect and analyze children’s multidimensional behavioral features using big data collection and analysis.Psychological development most rapidly takes place throughout the early years of life. It is possible to obtain the emotional changes in children’s personalities and characters using big data, which can not only capture the social and emotional changes in major events (such as earthquakes, tsunamis, and epidemics) but also the emotional changes in children’s personalities and characters When big data is used to examine the development of children’s psychological behavior, it is possible to recognize children who are abnormally developing in terms of their psychological and behavioral development and to undertake timely tracking and intervention [21–24].


### 2.4. Wearable Electronic Devices

Children will be able to collect their information via smart gadgets and connect it with information already available to doctors thanks to big data. With the help of intelligent sensors, the cloud health monitoring and early warning system, which is based on internet-of-things technology, continuously monitors children’s surrounding environmental parameters, vital signs parameters, exercise status, and other relevant information in real time (such as gait, heart rate, blood oxygen saturation, physical activity, and sleep habits).Additionally, information gathered from children’s wearable devices can be used to analyze the health status of children of a specific gender and age, conduct health research based on geographic location, population, or socioeconomic level, and formulate or adjust policies based on the results of this research [25–27].


### 2.5. Disease Surveillance and Management Are Also Important

The cross-integration of the internet, wearable gadgets, and big data makes disease monitoring and management for children much more convenient. It is possible to create children’s health records using big data in a dynamic and comprehensive manner (including physical examinations and laboratory tests, imaging, and behavioral habits, among other things), which makes it easier for medical staff to formulate the best plan for children’s drug treatment, behavioral intervention, and rehabilitation training. These big data will assist hospital administrators in predicting the lineup of medical staff that will be required on a daily basis, allowing them to reduce the amount of time that patients must wait to see a doctor and provide better medical services for children.The analysis and exploitation of electronic medical records (EMRs) are one of the most powerful applications of big data. Personal medical history, family medical history, test findings, and medications are all contained inside electronic medical records. It was previously impossible to transmit medical records between different medical organizations due to privacy concerns. It is possible to standardize and integrate different original medical records of patients using big data analysis technology, resulting in improved children’s health records. The availability of a diverse range of children’s health records may result in improved regulations and improved medical care. It is easier for medical personnel to understand the disease dynamics of children and to change medicine when they have access to a comprehensive electronic medical record. It is also a valuable source of information for medical researchers conducting studies [28–32].Large amounts of data are used in medical imaging (X-rays, MRI, and ultrasound). This is all part of the medical process. Previously, radiographers and sonographers had to individually analyze each test result, causing labor and delays in patient care. Artificial intelligence can perform some diagnostic tasks. Hundreds of thousands of photographs can be used to develop an algorithm that finds patterns in images, and these verified models can help clinicians make medical diagnoses. Because big data algorithms can identify diseases and symptoms from vast amounts of data, they can help radiologists find anomalies they might otherwise miss.


### 2.6. Pediatric Medical Training and Practice

Through the use of virtual reality, augmented reality, and online education, physicians in medically underserved areas and grassroots institutions can communicate and train with professionals in a timely manner. These technologies will significantly improve the current condition of scarce pediatric medical resources and will encourage the precise placement of high-quality medical resources in a targeted manner. Using an intelligent algorithm of big data, practical training plans can be developed according to the preferences and needs of pediatric medical care, which can accurately match and intelligently push the content of children’s growth and development and nutrition, psychology, health education, and case discussion, thereby improving the professional ability of pediatricians. Meanwhile, AI technology can collect, analyze, and provide feedback on data and information related to children’s health through algorithms and software. This can assist pediatricians in screening children’s psychological and behavioral development, providing nutritional guidance, and intervening in children’s growth and development during their early years.


### 2.7. Public Health and Safety

Patients’ information will be collected in large quantities to allow for the detection of diseases at the earliest feasible stage. Patient care can be improved if the disease and its progression can be predicted in advance. In addition, the likelihood of some diseases suddenly occurring can be minimized to some extent if disease and its progression can be foreseen beforehand. Humans can forecast the outbreak trend of infectious illnesses, minimize infections, lower medical expenditures, and provide patients with more convenient services by analyzing large amounts of health-related data. With the study and implementation of big data technology in the field of health administration through the analysis and mining of physical examination data, it is possible to determine the health variations between different regions and populations (for example, by age-group or by chronic disease group) and then to develop tailored, regional healthcare plans. For the purpose of formulating scientific methods of disease prevention, treatment, and prediction, a complete health assessment model has been established.Not only can humans forecast epidemic disease outbreak trends, prevent infection, and reduce medical expenditures, but they can also provide patients with more convenient services as a result of medical data analysis and interpretation. Relevant scholars have used big data to track the trend and infection coefficient of new coronavirus pneumonia in China since the global outbreak began and have made targeted recommendations for addressing the issues that have arisen as a result of the epidemic. Humanity's powerful ability to control goes a long way in preventing the spread of disease both domestically and internationally.

## 3. Correlation Study

The health status of 1,000 children is shown in Figure2.Figure 2
Classification of children’s health status.Among the 1,000 cases of children, 85 cases were excellent in physical health, 430 cases were qualified, the number was the largest, and 245 cases were unqualified.Logistic regression results are shown in Table1.Table 1
Logistic regression results.
Risk factorsBXCPGender0.24323.95230.0401Gestational age−0.36554.67550.0321Constant0.14550.00000.9813It was discovered in this study that there is no statistically significant difference in the qualified rate of physical fitness across age-groups and that the qualified rate of male children is significantly higher than the qualified rate of female children. As a result, it is clear that the qualified rate of physical fitness and gender-related variables have a positive relationship. According to the perspective of movement coordination and ability, as motor cognition and muscle and nerve development progress to completion, the unique characteristics of various muscle groups in the body in terms of working methods and contraction strength become more economical and orderly, which benefits overall health. The difference in neuromuscular system development between children aged three and six years is one of the most significant factors contributing to the disparity in physical health between the two groups. In terms of anatomy and physiology, men and women differ in terms of physiology and textural structure, resulting in men’s body functions being slightly superior to women’s body functions. As a result of these demographic differences, boys and girls develop physically differently, and the methods used to guide their growth are also diverse, which benefits both children’s healthy development.The term “gestational age” refers to the period of time between sperm and egg fusion and delivery. According to the findings of the study, postpartum newborns have a much greater rate of physical fitness than full-term and preterm infants. The results of this study are congruent with the findings of Gong Yueting et al., who found that gestational age is a significant factor in disparities in physical health among young children. According to research conducted by Luo Ying et al., the influence of gestational age factors on the physical health of 3- to 6-year-olds is inversely connected with their physical health. Ingestion of harmful substances results in poor physical health.Physical activity has a significant impact on the physical state of children in their early years, and it is an activity that young children should prioritize as they progress through the developmental process. Along with contributing to children’s physical development, increasing their body immunity, and promoting healthy growth, scientific sports contribute to children’s psychological development, expanding their spiritual world, and instilling a strong sense of morality in children. According to pertinent research, children who engage in physical activity have higher levels of physical fitness and a more mature mental development than children who do not engage in physical activity. Children who participate in scientific physical activity between the ages of three and six years old have a greater chance of experiencing future growth and have stronger bodies.


## 4. Physical Health Risk Assessment System for Young Children

The central control chip, which is analogous to the human brain, is the nerve center of the children’s physical health risk assessment system. It is entirely in control of the risk assessment system. This device is primarily responsible for the uninterrupted conversion of the obtained analog signals to data signals and for the conversion of the collected data signals. Digital signal processing performs two functions: digital filtering and data transmission. The MCUs are advantageous due to their small size and low power consumption. It is capable of gathering and digitally filtering signals at high processing speeds by utilizing one or more on-board USART communication interfaces, which reduces the amount of configuration required for the underlying registers to a certain extent. Multiple A/D converters operating at a higher clock frequency are integrated into the MCU to convert analog signals with a resolution greater than 16 bits to data signals. As a result, fewer peripheral circuits are required to perform the associated functions, which alleviates transmission issues. It is possible to enhance performance stability.The MCU, which serves as the digital circuit’s processing center, has the ability to issue instructions to the entire system’s hardware. The reset circuit, power supply circuit, a crystal oscillator circuit, and program circuit are the four circuits that make up the simplest MCU system. When the MCU is thrown beyond of a specified range, the reset circuit ensures that it returns to its initial state. The crystal oscillator circuit guarantees that precise internal and external clock sources are delivered to the MCU circuit, and the program circuit imports the program into the MCU interface in order to ensure that the MCU chip normally operates. Figure3 depicts the MCU system and circuit at its most basic level. Among the 1,000 cases of children, 85 cases were excellent in physical health, 430 cases were qualified, the number was the largest, and 245 cases were unqualified.Figure 3
The MCU minimum system and circuit.When it comes to quantifying the physical and health risks associated with young children, this design takes an interdisciplinary approach. The risk calculation model from the information security risk assessment guide is used as the risk assessment model in this system design because it matches the features of the research object. The following is a diagram of the specific risk calculation formula’s building blocks:(1)A=fB,C,D=fEi,GJi,D,where A represents the physical health risk of students and children, B represents the BMI of children, C represents the vulnerability of children’s mental health, D represents age, E represents the impact of risk on children, G represents students’ own health level value, and J represents the physical vulnerability of children.The risk calculation formula in equation (1) is deduced as follows:(2)A=fT,Y,U,where A represents the quantified risk value, T represents the physical condition of the child, Y represents the health condition of the child, and U represents the psychological condition of the child.Then, we have(3)A=T⋅Y⋅U.In this study, the basic principle of fuzzy logic is used as the main method of physical health risk assessment for young children:(4)fg:G⟶0,1,g⟶fg=g0∉X,g1∈X,where fg is the characteristic function of G. The consistency of the matrix is(5)CI=λmax−nn−1,CR=CIRI,where CR is the tested coefficient; when CR < 0.1, it is judged that A has satisfactory consistency.The membership function is(6)αxg:X⟶0,1,g⟶αxg.Then,(7)fxG=g−tp−t,where t≤g≤p.For the purpose of evaluating the effectiveness of the design system described in the text, two commonly used systems on the market are selected and compared to the design system described in the text. The establishment of a realistic testing environment is essential for the successful completion of the comparison test of the three systems and the stability of the testing process. Therefore, in order to maximize the efficiency and stability of data operation, the system test environment uses a distributed design with one server serving as the main node and three data processing servers serving as nodes.This system test will involve the quantitative processing of children’s physical health data extracted from the SQL database and output to the test platform during the testing procedure. The purpose of this study is to compare the design system described in this study to two currently used evaluation systems, the CES and the TCS, in order to evaluate and analyze the risk situation depicted in the aforementioned target data, as illustrated in Figures4–6. The results of the risk value calculation are used as comparison indicators in this system evaluation test. Multiple tests will be used to improve the accuracy of the comparison results in this system test. The system test should be completed in accordance with the abovementioned system test scheme in order to obtain effective system test analysis results.Figure 4
VaR calculation result.Figure 5
Estimated level query accuracy.Figure 6
System assessment processing time.As demonstrated by the results of the preceding tests, the dependability of the calculated design system risk value in this study is quite high, as demonstrated by the results of the preceding reliability tests. According to the results of the system testing, it can be concluded that the results of this work’s risk value calculation are reasonably consistent. The calculations’ accuracy is maintained at or above 96 percent for an extended period of time during the process of multiple calculations, and the range of up and down variations is small, demonstrating the system’s calculating reliability during this process. As demonstrated in this work, when compared to the calculated VaR values for the intended system, the calculated VaR values for the CSE and TCS systems exhibit significant swings. This is due to the fact that the CSE and TCS systems are more volatile. According to prior research, risk assessment findings are less likely to significantly fluctuate, and it can be concluded that the currently used assessment method is insufficiently capable of quickly calculating the risk value.


## 5. Conclusions

Multiple logistic regression was used to analyze the factors influencing the physical health of young children by reviewing the physical examination results of 1,000 cases of young children in hospital health examinations from June 2019 to June 2021 in a SQL database. Additionally, a risk assessment system for young children’s physical health was established. To maximize the effectiveness of the assessment, a new type of physical health risk assessment system for young children was developed on the basis of the original physical health risk assessment system for young children. The hardware portion of the system is optimally designed, including the main control chip and the smallest system circuit. Simultaneously, a risk assessment model for young children’s physical health is developed to facilitate the process of quantifying risk. The fuzzy logic fundamentals are used to calculate the affiliation of risk values, and the assessment results are incorporated into this step of the calculation to obtain an accurate assessment level. At this point, the design of the system for assessing physical health risks in young children is complete. The system’s test session was constructed, and it was discovered that it can be used with a maximum accuracy of 96 percent for assessment-level queries and a minimum detection time of 5 seconds. In the future, we will introduce a deep learning model to further improve the accuracy of physical risk assessment of children.
