ГИГИЕНИЧЕСКОЕ ВОСПИТАНИЕ ШКОЛЬНИКОВ КАК СРЕДСТВО ПРОФИЛАКТИКИ НЕБЛАГОПРИЯТНОГО ВОЗДЕЙСТВИЯ ВНЕШКОЛЬНЫХ ФАКТОРОВ

Preservation and strengthening of children and adolescents' health is one of the most important direc-tions of the state policy of the Russian Federation. Purpose of the study: to assess the effectiveness of hygiene education techniques to prevent adverse effects of out-of-school factors on the health of schoolchildren. Materials and methods: In the dynamics from 2017 to 2019 in three educational or-ganizations of Astrakhan the hygienic education of schoolchildren and their parents was carried out. The influence of extracurricular factors on schoolchildren's health was assessed on the basis of a risk-based model. A total of 1940 Astrakhan schoolchildren aged 7–17 (878 boys and 1062 girls) partici-pated in the questionnaire-based survey. The data was statistically processed using Microsoft Office Excel 2007. Results: A cause-effect relationship was found to be 95,0 %, RR = 6,40, CI = 4,92–8.33, the etiological component was 67,5 %, sensitivity was 0,889, specificity was 0,778. There was a caus-al relationship between occurrence of myopia and failure to perform eye exercises by school children at home, 95,0 %, RR = 1,80, CI = 1,52–2,15, etiological component 26,7 %, sensitivity 0,750, speci-ficity 0,500. A causal relationship was found between the occurrence of musculoskeletal disorders and the use of shoes that did not meet hygienic recommendations, including those outside educational institutions – 95,0 %, RR = 1,75, CI = 1,50–2,00, etiological component 25,0 %, sensitivity – 0,700, specificity – 0,500. Within the framework of the conducted activities short recommendations – check-lists on the rational organization of the day and nutrition, motor activity, night sleep and leisure time organization were formulated. The information was also presented to the parents of the schoolchil-dren. Conclusion. Identification of intra-school and extra-school factors, establishment of cause-effect relationships and evaluation of possible adverse effects, will make it possible to develop relevant techniques of hygiene education, which will contribute to preservation

Early temperament and physical health in school-age children: Applying a short temperament measure in a population-based cohort.

Temperament has drawn considerable attention in the understanding of behavioural problems and psychopathology across developmental stages. However, less of a focus has been placed on the role of temperament in physical aspects of health. We aimed to examine the relations between early temperament traits and physical health in school-age children. This study used longitudinal data of 18,994 children (52.4% boys) born in 2005 from the Taiwan Birth Cohort Study, in which follow-up surveys were conducted via face-to-face interviews with the child's caregiver. Temperament at 5.5 years of age was assessed using a nine-item measure, and two higher-order temperament traits, surgency and regulation, were derived through confirmatory factor analysis. Physical health outcomes at age 8 included caregiver-rated general health status and medically attended injuries. Multiple logistic regression analysis was applied, with the child's birth outcome, early health status or injury history, health behaviours and family socioeconomic status as control variables. The results indicated that higher levels of surgency and regulation, as early temperament traits, significantly predicted lower odds of caregiver-rated poor health in later years. Higher level of regulation was also associated with lower odds of injury risk. Our findings suggest that assessing early temperament traits could be useful for the promotion and management of physical health in young school-age children.

Development of Health Screening Information System for Elementary School Children at Dalam Kaum Sambas Public Health Center, Sambas Regency - West Kalimantan

Dalam Kaum Sambas Public Health Center is one of the public health centers that carry out the main activities of health improvement efforts in the form of promotive and preventive efforts, namely health screening for elementary school children, which are carried out manually, causing problems such as the length of recording, drawing conclusions based on examination results and recapitulation that are at risk of errors. This study aimed to develop an Information System for Primary School Children's Health Screening (SIPEKASDA) at Dalam Kaum Sambas Public Health Center. This research method is Research and Development (R&D) with system design using the Waterfall model and system evaluation with the EUCS End User Computing Satisfaction (EUCS) model. The design of the Information System in this study includes a Data Flow Diagram, Flowchart, Entity Relationship Diagram and User Interface, which produces an Information System with several menus, namely processing student data, parents, student class mapping, health checks and recapitulation of school-based health check results. The results obtained from SIPEKASDA include; the presentation of examination results data and recapitulation of examination results per school, village and sub-district. SIPEKASDA is a website-based information system that can be accessed anywhere and anytime. The quality of the Primary School Children's Health Screening Information System assessed from the evaluation of information systems using the End User Computing Satisfaction (EUCS) model is very good, which reaches 83.58%, so the information system can be relied on if you need data at any time. One of the principles of using information systems is timelines or the speed of information systems in responding to what is done by its users, presenting data promptly and up to date so that the use of information systems can increase. Problems in recording inspection results, data processing, data recapitulation, report making, and ease of accessing the system can be adequately resolved after the system is made.

Characteristics and effects of school based physical activity programs for schoolchildren with autism spec-trum disorder: A scoping review

Although benefits have been reported from the practice of physical activity in children with autism spectrum disorder (ASD), to a lesser extent the characteristics of the programs carried out in the school context and their effects on health are known. The objective of this review was to characterize school based physical activity programs and their effects on the health of schoolchildren with ASD. The review was carried out in accordance with the PRISMA statement in the databases, Medline and PsycINFO, between the years 2010 to 2023. A total of 20 articles were analyzed. A total sample of 683 schoolchildren with ASD (x̄=10.5 years and 73.1% male) were included. Schoolchildren with ASD had 98.1% adherence to the programs. The school based physical activity programs were mainly based on aerobic exercises, such as walking, jogging, running, and cycling (45% of the articles) with a duration between 10-16 weeks (55% of the articles), with a frequency of 2-3 times a week (60% of the articles) and with 60-minute sessions (45%). On the other hand, the most studied variables were language and motor skills (60% of the articles) and psychosocial and cognitive function (50% of the articles); together with the variables of physical and nutritional activity, these were where a higher percentage of articles with positive effects were found. The findings suggest a profile of schoolchildren with ASD and the main characteristics of school based physical activity programs in schoolchildren with ASD in terms of their extension, frequency, duration, intensity, location and provider as well as the variables most frequently evaluated and with the greatest positive effects. Keywords: Exercise; Autism Spectrum Disorder; ASD; Cognition; Physical Activity; Scoping Review.

Exploration of Sex and Age as Moderators Between Social Cumulative Risk and Sleep in a Representative Sample of Children and Adolescents Living in the United States.

Youth who face adversity are at a disproportionate risk for poor sleep health across the life course. Identifying whether the association between adversity and poor sleep varies based upon age and sex is needed. This study aims to explore sex and age as moderators between social risk and sleep in a sample of U.S. youth. This study analyzed data of 32,212U.S. youth (6-17years) whose primary caregiver participated in the 2017-2018 National Survey of Children's Health. A social cumulative risk index (SCRI) score was calculated from 10 parental, family, and community risk indicators. Nighttime sleep duration was the number of hours the child slept during the past week. Weeknight sleep irregularity was operationalized as whether the child sometimes/rarely/never went to bed at the same time. Generalized logistic regression models estimated associations between SCRI and sleep duration/irregularity, with age and sex as moderators. Age moderated the association between SCRI and short sleep (OR = 1.12, p < 0.001), such that the magnitude of the SCRI-sleep relationship was 12% greater in school-age children. Sex was not a significant moderator. In stratified models by age group, age was positively associated with short sleep in both groups, with a greater magnitude in school-age children. Female school-age children were less likely to have short sleep than males. Younger children with greater social cumulative risk factors may be more vulnerable to short sleep duration. Further research into the mechanisms underlying the relationships between social risk and sleep health in school-age children is needed.

Videoconference‐led art‐based interventions for children during COVID‐19: Comparing mindful mandala and emotion‐based drawings

AbstractEmerging evidence on the coronavirus disease 2019 (COVID‐19) pandemic suggests that children are experiencing a deterioration in mental health, namely, an increase in anxiety, depression, and hyperactivity symptoms. To address this rising issue, preventive strategies and mental health interventions need to be evaluated to help children in their school setting. Recent studies have suggested that art‐based interventions could increase children's well‐being and be easily implemented in schools. The goal of this study was to assess the effects of an emotion‐based directed drawing intervention, compared to a mandala drawing intervention, on elementary school children's (n = 165) mental health, in the context of the COVID‐19 pandemic. An experimental design was used to compare the effects of the two interventions on primary school students' anxiety, depression, and inattention symptoms. All drawing activities were led by an online facilitator, while children and teachers attended school in‐person. Mixed analyses of variance revealed a significant effect of time on students' levels of anxiety. Post hoc sensitivity analyses indicated that children from both groups reported lower levels of anxiety pre‐ to postintervention. Results from this study showed that, in the context of the COVID‐19 pandemic, both emotion‐based and mandala drawing interventions could improve certain mental health aspects of elementary school children, by reducing their anxiety levels. Informal evidence indicates that implementing these interventions online and remotely through a videoconferencing platform is feasible and well received by children and their teachers. Nevertheless, future studies should include an inactive control group, explore the acceptability of the intervention, and use longitudinal methods to better document if the positive impacts on mental health can be maintained through time.

Peningkatan Pengetahuan Perilaku Hidup Bersih dan Sehat (PHBS) tentang Jajanan Sehat di MI PUI Cicanggong Kawali

Introduction : Improving health status is strongly influenced by behavioral factors, namely proactive behavior that is useful for maintaining and improving health, preventing the risk of infection, protecting oneself from disease threats and actively participating in community empowerment activities called the Health Promotion Center, since 1996 known as the Behavioral Program. Clean and Healthy Living (PHBS). The health of school children is currently a priority scale, from the results of the 2013 population census it was found that a group of children in Indonesia totaled around 66 million people / 28% of the total population in Indonesia. Elementary school children are an age group that is vulnerable to nutrition and disease, especially infectious diseases. Objective : The purpose of this counseling is to improve the knowledge of grade 4 MI PUI Cicanggong students about healthy and nutritious snacks, as well as efforts to reduce the poor nutritional status of snacks. Method : The methodology of health education that incorporates self-management. Participants in this counseling are anticipated to be able to apply a complete strategy, particularly in the creation of new behaviors, specifically PHBS in the school setting as well as the community. Result : From the results it can be concluded that before carrying out health counseling as many as 6 people (22.2%), participants were able to answer questions before the material was delivered, 15 people did not know (71.0%) participants did not know about healthy snacks, 4 people (14.8 %) participants did not know participants did not know healthy snacks. then after carrying out health education, the knowledge of participants about healthy snacks PHBS increased to 25 people 100%. Conclusion : Increasing knowledge about healthy snacks is a good start to instill clean and healthy living habits in schools. So, after knowing the characteristics of unhealthy snack food and the dangers of unhealthy snack food, it is hoped that students will not buy unhealthy.

Influence of length of use of the Information and Communication Technologies on the health of school-age children

Introduction: The use of the Internet is becoming increasingly important in enabling children and adults to fully participate in society, whether it is learning new skills or connecting with friends and family. Consequently, children's opportunities are increasingly dependent on the Internet. The advance of technological innovations has resulted in more and more ICT devices being available to children, contributing to the deterioration of children and adolescents' health.&#x0D; Methods: The study was designed as an epidemiological, cross-sectional, descriptive-analytical, comparative study. The study was conducted from October 18, 2021, to January 16, 2022, using an online questionnaire accessible through the Microsoft Forms platform. Respondents were able to access the questionnaire via a link or QR code located on the child's consent form for participation in the study, which was previously signed by a parent/guardian.&#x0D; Results: The results of the study showed that school-age children were the most frequent users of smartphones and watches TV, with male respondents spending more time using almost all ICT devices, with the exception of tablets, which were used more frequently by female respondents. The analysis of pain intensity in the use of information and communication technologies revealed that respondents most frequently experienced mild pain, especially in the neck/shoulders and lower extremities. The frequency of eye problems after using ICT devices was found to be occasional, with the most pronounced symptoms being fatigue, tearing, and eyestrain, as well as headaches in one in five respondents.&#x0D; Conclusion: Increasing frequency of ICT device use was associated with higher pain intensity in all anatomic regions. A 1-hour increase in weekly ICT device use also increased the likelihood of pain intensity in all anatomic regions, including eye symptoms and headaches. High exposure to ICT is of concern because it leads to adverse health outcomes for children.

Features of the formation of health care competence of school students in physical education lessons

The purpose of the work: to analyze the current state of the formation of health-preserving competence in physical education lessons in general secondary education institutions. Methodology: analysis and generalization of methodological, psychological-pedagogical and educational-methodical literature, which gave an opportunity to study the peculiarities of the formation of health-preserving competence in physical education lessons. Scientific novelty: the article examines modern approaches to the formation of health-preserving competence of schoolchildren in physical education lessons.&#x0D; Conclusions: at the current stage of the country's development, the issue of student youth's health occupies a prominent place in the education and upbringing of the younger generation. The main reasons for this situation are a lack of physical activity, which in turn negatively affects the physical development and health of schoolchildren. Currently, general secondary education institutions do not fully solve the problem of meeting the biological need of schoolchildren to move. Physical education lessons at school compensate for only 15% of the need for children's bodies to be physically active. The formation of health-preserving competence of schoolchildren is a purposeful process of forming a positive motivational and value orientation towards a healthy lifestyle, students' mastery of knowledge, skills to conduct health-preserving activities, experience of health-preserving; development of personal qualities, which is carried out by means of health-saving technologies, taking into account the specifics of the functioning of school institutions.

School Children's Health Screening at SDN Bangsal 1 with Puskesmas Pesantren 1 Kediri City

The guidance and development of School Health Business (UKS) in schools is carried out through three main programs (known as the UKS trias) which include health education, health services, and fostering a healthy school life environment. The health services in question include school children's health screening, otherwise known as health screening; health monitoring; and health education. The purpose of this community service is to conduct a health screening of school children at SDN Bangsal 1 Kediri City. The school health screening program will be held in February 2022, precisely at 08.00 – 12.00. The health tests carried out include eye health, ear health, skin health, teeth and reproductive health tests. An eye health test is conducted to determine whether the student suffers from color blindness, low vision, cataracts, or other diseases. A skin health test is done by checking whether there are red spots on the skin. In addition, health tests are also added to other body parts. This community service is carried out in collaboration with the Pesantren 1 Public Health Center, Kediri City. From the screening results, it was found that the health of the students of SDN Bangsal 1 Kediri City did not show any serious diseases, but some eye problems were found. The action taken by the school for students with health problems was to refer to the Pesantren 1 Public Health Center which is not far from the school, by bringing a referral letter given by the examining doctor at the health screening. The health screening program is one of the school's flagship programs. It is hoped that the students of SDN Bangsal 1 Kediri have more awareness to maintain health.

Diabetes Management in Danish Primary School: A Survey of Experiences of Parents of Children with Type 1 Diabetes

Supporting diabetes self-care in school is important for optimal glycemic control and mental health. The aim of this study was to investigate parental experiences of diabetes management in Danish schools, with an emphasis on the importance of school staff support in self-care. This cross-sectional study surveyed parents of schoolchildren with type 1 diabetes aged 6 to 16 years in Denmark. The parents were identified among members of the Danish Diabetes Association and were invited to complete an online questionnaire. A total of 252 parents of schoolchildren with type 1 diabetes answered the questionnaire. Only 28% of the children had a designated staff member responsible for support in diabetes self-care during school hours. Having a designated staff member responsible for support in self-care was positively associated with parental experiences of better school–parent cooperation (p &lt; 0.001), better experience of diabetes management in school (p &lt; 0.001), and larger proportions of children and parents feeling comfortable in school (p = 0.022 and p = 0.049, respectively). School staff support was positively associated with better parental experience of diabetes management and with some parameters of mental health in schoolchildren with type 1 diabetes and their parents in Denmark.

An appraisal of the implementation of the national school feeding programme and its effect on enrolment and attendance in public primary schools in Southeast, Nigeria: perception of heads of schools

IntroductionThe National Home Grown School Feeding Programme (NHGSFP) was re-launched in Nigeria in 2016, eleven years after it was first introduced in the country, with Enugu as one of the beneficiary States. The objectives of the programme are to improve the health of school children and aid in the realization of Universal Basic Education (UBE) goals. This study explored the opinions of heads of public primary schools on the implementation and policy benefits of NHGSFP in Enugu, southeast Nigeria.MethodsThis was a cross-sectional study conducted among 24 headmasters and headmistresses purposively selected from public primary schools in the Enugu metropolis. Qualitative data were collected through the use of a pretested Key Informant Interview (KII) guide, and analyzed using a thematic approach.ResultsAll the participants were aware of the NHGSFP, which involved the provision of one mid-day meal per child per school day to the pupils, and all their schools were part of the programme. Most of the participants complained about the nutritional quality and quantity of the school meals which they felt were poor. None of the schools had a kitchen within the school premises, and all the participants admitted that deworming was not regularly carried out, as part of the programme. Most of the participants believed that the objectives of the feeding programme, including, reduced hunger among learners, increased school enrolment, attendance and enhanced participatory learning, were being met.ConclusionAlthough the NHGSFP was implemented in every school in Enugu metropolis, Enugu State, Nigeria, regular deworming of pupils was not carried out, and there were concerns about certain aspects of the implementation, such as inadequate funding and poor quality of school meals. Thus, there is a need for the introduction of deworming and more allocation of funds to the programme to improve the quantity and nutritional quality of school meals.

Самооценка состояния здоровья и образа жизни как основа формирования представлений школьников о здоровьесбережении

The article describes the possibility of using the data on the health status and lifestyle self-assessment obtained during the questionnaire survey of high school students in the teacher's preventive activities aimed at preserving and improving the schoolchildren's health. The main indicators that according to the respondents determine their quality of life have been revealed, and health status is ranked only third. It has been found that 40% of students consider their health to be “good”, while 53% currently do not worry about their health at all. Certain characteristics of physical activity, nutrition, sleep schedule, prevalence of bad habits in students attending schools of various types are provided. Despite high subjective assessment of physical activity, only 8% of schoolchildren do morning excercises every day, most of students do not attend sports sections. More than 40% of students sleep less than seven hours, which has a negative effect on the adolescents' health. Evidence has been obtained that 19% of schoolchildren have tried vaping and 13% vape regularly, which is definitely worrisome.

Moderating the impact of the COVID-19 pandemic on children's and adolescents' substance use, digital media use, and mental health: A randomized positive psychology addiction prevention program

ObjectivePrevious research suggests that well-being interventions are effective in moderating substance and digital media use and improving mental health. This study evaluated the feasibility and preliminary efficacy of a school-based Positive Psychology Addiction Prevention (PPAP) intervention aimed at reducing substance and digital media use and increasing the mental health of school children during the COVID-19 pandemic. MethodsThe sample was composed of 1,670 children and adolescents (Mean age = 12.96, SD = 2.01) from six elementary and secondary schools in Israel who were randomly assigned to the PPAP intervention (n = 833) or the waiting-list control conditions (n = 837). A three-year longitudinal repeated-measures randomized control design was used to examine modifications in substance use, digital media use, and psychological symptoms in the intervention and control groups assessed on the pre-test (before the outbreak of COVID-19, September 2019), the post-test (May 2021), and the 12-month follow-up (May 2022). ResultsThe 12-month prevalence of tobacco use, alcohol use, and cannabis use decreased significantly from the pre- to the follow-up period in the intervention group, and increased significantly in the control group. Daily digital media use increased during the pandemic period in both groups, with a significantly higher increase in the control group. The intervention group reported significantly lower psychological symptoms and negative emotions, and greater positive emotions and life satisfaction after the intervention and at follow-up compared to the control group. ConclusionsThe COVID-19 pandemic has profoundly disrupted the lives of children and adolescents. Well-being and addiction prevention interventions may be effective in improving the mental health of school children during pandemics and crisis periods.

Impact of fine particulate matter and toxic gases on the health of school children in Dhaka, Bangladesh

Background. Air pollution exposure has a detrimental effect on children who spend more than 17% of their weekdays inside a school building. The purpose of this study is to look into the effects of particulate matter (PM) and toxic gases on health of the school children. Between April and November 2018, samples were collected in real time from ten different schools (both indoor and outdoor) over four hours on two consecutive days at each school. During the first two hours, when students were present in the classroom, measurements were conducted inside the classroom. After that the measurements were conducted outside the classroom but within the school premises - when students were playing on the playground or eating breakfast outside of classroom. Method. To evaluate the impact of air pollution, 250 students (on average 20 students from each school) aged from 9 to 12 were selected from ten schools. Automatic monitors (AEROCET 531S, USA) were employed to measure PM1.0, PM2.5, and PM10 concentrations. NO2, TVOC, and CO2 concentrations were measured using an AEROQUAL (500S, New Zealand), and the respiratory rate is measured by BSMI Peak Flow Meter (Made: BSMI, Origin: China). Monitors were placed at about 2.0 meters above the floor at breathing height and no student wore the sensors. The ANOVA test was conducted to see the statistical significance between air quality parameters and peak flow meter readings. Results. The mean ± standard deviation of PM1.0, PM2.5, and PM10 concentrations were 19.1 ± 3.6, 34.2 ± 10.1, and 131.3 ± 58.6 μgm−3, respectively. PM2.5 and PM10 concentrations exceeded WHO standards (15 and 45 μgm−3 of 24 h) by 2.3 and 2.9 times. The highest concentrations of toxic gases were found on school campuses where vehicle densities (measured manually) were high. The mean Hazard Quotient (HQ) for PM10 (2.5 ± 2.2 indoor; 3.6 ± 2.6 outdoor) and PM2.5 (1.8 ± 0.8 indoor; 1.9 ± 1.0 outdoor) among all participating students was >1 indicating an unacceptable risk for human health. Lung function associated with the PEF value has a negative correlation with PM1.0 and PM2.5 concentrations in most cases. Conclusions. The findings of this study are useful in gaining a general understanding of the school environment in Dhaka. It aimed to understand how children were personally exposed in school and to develop effective control strategies to mitigate negative effects.

ABSTRACT During the COVID-19 pandemic, children in school base exposed to more gadgets than 2-3 hours/per day. Position less body good moment using gadgets, poor intensity lighting good so will harm the eye's health. The purpose of the service program Public is to increase the independence of students in doing eye exercises and a combination of relaxation, knowledge, and eye health for Overcoming Computer Vision Syndrome (CVS) for Elementary School Children. devotion Public This approach is participatory and active by sustainable. The activity consists of educating teachers and students about essential health eyes and impact CVS, giving eye exercise training to teachers and students, evaluating skills and knowledge, and advocating a party school for regulation does eye exercises combination applied relaxation routine at school. Monitoring and evaluation with the use of questionnaires and carrying out monitoring and evaluation with the use of questionnaires and sheets observation. Activity will be held for two months, starting from March until the moon of May 2022, at Inpres 25 Elementary School, Sorong City. The audience target for this activity is teachers and school students based in district Push, as many as 46 people. The results of this community service show that the average score of knowledge about eye health increased by 28.5 points, and the average eye health score increased by 8.5 points. After education, average grade knowledge, and eye health increase, participants could do eye exercises with combination relaxation independently. Empowerment Public in health eyes on children's school needs to be carried out by the government city push. We hope that the next community service can be focused on improving eye health in school children. Keywords: Eye Exercises, Elementary School, Covid-19

Chronic exposure to ambient PM2.5/NO2 and respiratory health in school children: A prospective cohort study in Hong Kong

Despite increasing concerns about the detrimental effects of air pollution on respiratory health, limited evidence is available on these effects in the Hong Kong population, especially in children. In this prospective cohort study between 2012 and 2017, we aimed to investigate the associations between exposure to air pollution (concentrations of fine particulate matter [PM2.5] and nitrogen dioxide [NO2]) and respiratory health (lung function parameters and respiratory diseases and symptoms) in schoolchildren. We recruited 5612 schoolchildren aged 6–16 years in Hong Kong. We estimated the annual average concentrations of ambient PM2.5 and NO2 at each participant’s address using spatiotemporal models. We conducted spirometry tests on all participants to measure their lung function parameters and used a self-administered questionnaire to collect information on their respiratory diseases and symptoms and a wide range of covariates. Linear mixed models were used to investigate the associations between exposure to air pollution and lung function. Mixed-effects logistic regression models with random effects were used to investigate the associations of exposure to air pollution with respiratory diseases and symptoms. In all of the participants, every 5-μg/m3 increase in the ambient PM2.5 concentration was associated with changes of − 13.90 ml (95 % confidence interval [CI]: −23.65 ml, −4.10 ml), − 4.20 ml (−15.60 ml, 7.15 ml), 27.20 ml/s (−3.95 ml/s, 58.35 ml/s), and − 19.80 ml/s (−38.35 ml/s, −1.25 ml/s) in forced expiratory volume in 1 s, forced vital capacity, peak expiratory flow, and maximal mid-expiratory flow, respectively. The corresponding lung function estimates for every 5-μg/m3 increase in the ambient NO2 concentration were − 2.70 ml (−6.05 ml, 0.60 ml), − 1.40 ml (−5.40 ml, 2.60 ml), − 6.60 ml/s (−19.75 ml/s, 6.55 ml/s), and − 3.05 ml/s (−11.10 ml/s, 5.00 ml/s), respectively. We did not observe significant associations between PM2.5/NO2 exposure and most respiratory diseases and symptoms. Stratified analyses by sex and age showed that the associations between exposure to air pollution and lung function parameters were stronger in male participants and older participants (11–14 year old group) than in female participants and younger participants (6–10 year old group), respectively. Our results suggest that chronic exposure to air pollution is detrimental to the respiratory health of schoolchildren, especially that of older boys. Our findings reinforce the importance of air pollution mitigation to protect schoolchildren’s respiratory health.
