Cardiometabolic disease is one of the leading causes of morbidity and mortality in adults. In recent years, the prevalence of cardiometabolic disease has increased year by year, becoming a major problem in the global disease burden. The occurrence and development of cardiometabolic risk are affected by many factors. Shift work as an occupational hazard has been widely concerned. Nurses are a typical population for shift work, but few studies have looked at the association between their shift work and cardiometabolic risk. This article reviewed the current situation of cardiometabolic risk and the research progress on the association between shift work and cardiometabolic risk among nurses. The results showed that cardiometabolic risk is prevalent in the nurse population. Shift work is associated with cardiometabolic risks such as metabolic syndrome, cardiovascular disease, diabetes, and dyslipidemia, and is mediated by circadian rhythm disorder, hormone secretion disorder, and stress response. However, the causal relationship between shift work and cardiometabolic risk is still unclear, and further prospective cohort studies should be conducted to improve the understanding of the impact of shift work on cardiometabolic risk in order to improve the cardiometabolic health status of nurses.

Abstract The construction of autism spectrum disorders (ASD) specialty cohorts in China is still in its infancy, and the cost effectiveness is insufficient when relying on diagnostic and treatment processes of child health care to collect ample and high quality data. After 2000, the United States Simons Foundation s ASD Research Initiative, the Early ASD Risk Longitudinal Investigation (EARLI), and the British ASD Study of Infant Siblings (BASIS), which have been built based on Internet recruitment, have provided new insight for the construction of large sample ASD specialty cohorts in China. Future research can further explore and optimize the methods of Internet recruitment, and establish a more comprehensive and accurate ASD specialty cohorts.

Abstract Chinese children and adolescents are experiencing dramatic changes in their lifestyle and the environment. Given the growing burden of myopia, obesity, and mental health problems among school age children, school health services are presented with new challenges. It is essential to promote and implement the underlying principle of "health first" for society as a whole, while aiming to improve the collective health literacy of schools, optimizing school health management systems, and adopting a comprehensive healthy school program in order to support every school to become a foundation for healthy living.

Abstract The physical and mental health issues of children and adolescents in China are becoming increasingly prominent. Integrating physical education deeply into the educational system and maximizing its role in fostering personal development, preventing common illnesses among students, and promoting mental health has emerged as the intersection of school health and sports. The article systematically arranges the development history and patterns of physical education in Chinese schools, summarizes the existing difficulties in the integration of physical education and educational system, and presents improvement suggestions to provide a basis for enhancing the integration system and promote the comprehensive development of children and adolescents.

Abstract The issue of multimorbidity in children and adolescents is becoming increasingly prominent, but there is no consensus on the definition of multimorbidity. As research deepens, issues related to the comparability and standardization of relevant findings are gradually emerging. As a solution, a systematic review of both domestic and international research on multimorbidity is conducted, and a classification system for defining the concept of multimorbidity is proposed, offering more convenient conditions for the advancement of future research and cross study exchange.

Objective: To analyze the association and dose response relationship between physical activity and inflammatory markers in college students, so as to provide a reference for promoting cardiometabolic health in college students. Methods: A cluster random sampling method was used to select 747 college students from two universities in Hefei, Anhui Province and Shangrao, Jiangxi Province from April to May 2019. Physical activity was assessed by using the International Physical Activity Questionnaire-Short Form (IPAQ-SF), and peripheral blood was collected to detect plasma inflammatory factor levels [including hypersensitive C reactive protein (hsCRP), interleukin-10 (IL-10), interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α)]. The differences between the groups were compared by using the χ 2 test and the Kruskal-Wallis rank sum test, and the association between physical activity and inflammatory markers was analyzed by using the Generalized Linear Model. The dose response relationship between physical activity and inflammatory markers was analyzed using the Restricted Cubic Spline Model. Results: The proportions of low physical activity, moderate physical activity, and high physical activity groups of college students were 15.9%, 53.7% and 30.4%, respectively. The levels of hsCRP, IL-10, IL-1β, IL-6 and TNF-α in the high physical activity group were 0.38(0.21, 1.10)mg/L, 70.74(47.90, 116.43)pg/mL, 1.75(1.21, 2.64)pg/mL, 4.33(2.93, 6.82) pg/mL , 5.27(3.89, 7.30)pg/mL,the levels in the low physical activity group were 0.80(0.31, 1.30)mg/L, 73.88 (47.90, 124.24)pg/mL, 1.88(1.42, 2.81) pg/mL, 4.82 (3.64, 6.67) pg/mL, 5.63 (4.34, 7.62)pg/mL, the levels in the moderate physical activity group were 0.63(0.25, 1.30)mg/L, 89.78(58.21, 127.65)pg/mL, 2.21(1.59, 3.27)pg/mL, 5.15( 3.72 , 7.72)pg/mL, 5.87( 4.63 , 8.00)g/mL, and the differences were statistically significant ( H=10.66, 11.38, 27.79, 14.13, 9.44, P <0.05). After adjusting for variables such as gender, body mass index, smoking, alcohol consumption and health status, the results of Generalized Linear Model showed that compared with the high physical activity group, the low physical activity group ( OR=2.20, 95%CI = 1.46- 3.31) and the moderate physical activity group ( OR=1.65, 95%CI =1.22-2.25) were more likely to have high levels of hsCRP, and the moderate physical activity group was more likely to have high levels of IL-1β ( OR=1.85, 95%CI =1.36-2.51), IL-6 ( OR=1.44, 95%CI =1.06-1.96), and TNF-α ( OR=1.43, 95%CI =1.05-1.94) ( P <0.05). The Restricted Cubic Spline Model showed that there was no linear dose response relationship between the time of moderate to vigorous physical activity weekly and IL-10, IL-6, II-1β, and TNF-α ( P <0.05). Conclusion There is an association between physical activity and inflammation in college students, and moderate to high intensity per week could reduce inflammation levels to promote cardiometabolic health in college students.

The incidence of gestational diabetes mellitus (GDM) is gradually increasing and has become a significant public health issue. Endocrine disrupting chemicals (EDCs) are a ubiquitous class of exogenous chemical substances that can interfere with hormone synthesis, metabolism, and activity, and subsequently affect endocrine homeostasis. Humans are extensively and continuously exposed to various EDCs originating from food packaging, plastic products, textiles, electronic goods, as well as cleaning agents and cosmetics in daily life, leading to endocrine and metabolic disorders, such as obesity, insulin resistance, impaired glucose tolerance, and diabetes. Previous studies indicated a close association between EDCs exposure and the occurrence of GDM. This review summarized the correlation between daily life exposure to EDCs and GDM, along with their potential biological mechanisms, including bisphenols, phthalates, per- and polyfluoroalkyl substances, organophosphate esters, parabens, and triclosan, aiming to provide scientific evidence for supporting the effective implementation of public health intervention measures to alleviate and prevent GDM.

Abstract The etiology and pathogenesis of myopia among children and adolescents remain unclear. As crucial regulatory mediators in the body, inflammatory cytokines have drawn increasing attention for their potential role in the onset and progression of myopia. The study examines the relationship between systemic inflammation and intraocular inflammation and myopia, explores the inflammatory mechanisms underlying myopia development, and discusses intervention strategies targeting related signaling pathways for myopia treatment. It aims to provide new insights for the prevention and control of myopia in children and adolescents.

Objective: To explore the association between light at night (LAN) of different intensities and ocular biometric parameters among preschool children, so as to provide a reference for optimizing strategies for myopia prevention and control. Methods: From November 2024 to January 2025, a cross sectional study was conducted among 369 preschool children from one kindergarten in Quanzhou City, Fujian Province. Questionnaire survey and eye examination were performed, and portable light sensors were used to collect LAN exposure data. Spearman correlation analysis was used to examine the associations between the duration of LAN exposure at different intensities and ocular biometric parameters. Generalized linear model was employed to explore the relationships between LAN duration at various intensities and ocular biometric parameters, while restricted cubic spline was used to investigate potential nonlinear associations. Results: The spherical equivalent (SE), axial length (AL), and axial length/corneal radius of curvature (AL/CR) for preschool children were 0.38 (-0.13,0.63) diopters, 22.35 (21.86,22.88) mm, and 2.86 (2.82,2.90), respectively. The median daily duration (interquartile ranges) of LAN exposure at intensities of 0, >0-100, >100-300, and >300 lx were 6.09(5.31,6.74), 1.74(1.13,2.42), 0.06(0.00,0.26), 0.00(0.00,0.00)h/d, respectively. The generalized linear model showed that for every additional hour of LAN at >100-300 lx, the AL/CR increased by 0.26 (95% CI =0.01-0.52); for every additional hour of LAN at >300 lx, AL/CR increased by 0.32 (95% CI =0.05-0.59) (both P < 0.05). No statistically significant associations were observed between SE or AL and LAN exposure at any of the intensity levels (0, >0-100, >100-300, and >300 lx) (all P >0.05). The restricted cubic spline model revealed that, except for the nonlinear relationship between LAN duration and AL at >100-300 lx ( P =0.02), all other light intensity levels showed linear correlations between LAN duration and preschool children s SE, AL, and AL/CR (both P >0.05). Time of day subgroup analysis revealed that during school days, for every additional hour of LAN at >100-300 lx and over 300 lx，AL/CR increased by 0.18 (95% CI =0.01-0.35) and 0.22 (95% CI =0.03-0.41), respectively (both P <0.05). However, weekend exposure showed no statistically significant association (all P >0.05). Conclusion Higher intensity of LAN is associated with increased AL/CR, and reducing exposure to LAN may have a potential protective effect on the visual health of preschool children.

In recent decades, the prevalence of neurodevelopmental disorders in children has been on the rise worldwide, and executive function plays an important role in early childhood development. Previous studies have shown that environmental endocrinedisrupting chemicals can enter brain tissue through the placental and blood-brain barriers, affecting neurodevelopment and jeopardizing children’s executive function development. During pregnancy, a special period for women of reproductive age, exposure to endocrinedisrupting chemicals not only affects intrauterine development, but may also have far-reaching effects on offspring health after birth. This article focused on reviewing domestic and international research literature on the effects of exposure to endocrinedisrupting chemicals [e.g., phthalates, polybrominated diphenyl ethers (PBDEs), perfluorinated and polyfluorinated alkyl substances (PFASs), and bisphenol A (BPA)] during pregnancy on offspring executive function published from 2015 to 2024, and further exploring potential associated biological mechanisms. Most studies pointed that endocrinedisrupting chemicals during pregnancy may affect children's executive function through triggering neuroinflammation, neurotransmitter disruption, and placental dysfunction. Specifically, exposure to phthalates and PBDEs during pregnancy is associated with reduced executive function in children, and the effects of PFAS and BPA are unclear. These findings suggest that more epidemiological studies and animal experiments need to be conducted in the future to deeply explore the effects of endocrinedisrupting chemicals exposure during pregnancy on children's executive function and its potential causal mechanisms, so as to provide new ideas for preventing neurodevelopmental disorders in children and promoting healthy development of children.
