Article Synopsis
- Telemedicine has shown promise as a supplement to traditional care, particularly for conditions like short stature, but more research is needed to determine its effectiveness as a standalone option and its impact on healthcare access.
- The study analyzed outcomes in 1241 children diagnosed with short stature in China, comparing those receiving only in-person care to those using a combination of in-person and telemedicine services.
- Results indicated that the telemedicine integrated care group experienced a greater increase in height compared to the in-person care group, highlighting its potential effectiveness in managing this condition.
Background: There are little recent data in China regarding contemporary nutritional inequities among children and adolescents, particularly in relation to urban-rural residence and regional socioeconomic status (SES). We aim to assess inequalities in thinness and obesity in Chinese children and adolescents.
Methods: Weight and height measurements for 1 677 261 children and adolescents aged 7-18 years were obtained from seven cycles of the Chinese National Surveys on Students Constitution and Health (1985, 1995, 2000, 2005, 2010, 2014, and 2019).
Phthalates (PAEs) are synthetic compounds extensively employed in consumer products. Blood pressure (BP) in children can vary, the degree of visit-to-visit BP variability (VVV) is at least partially independent of BP. The interactions between PAEs exposure, pubertal-related genetic susceptibility and lifestyles on childhood VVV are not investigated.

- The study addresses the growing issue of metabolic-associated steatotic liver disease (MASLD) in children, particularly those in obesity-heavy regions, highlighting the challenge of identifying at-risk individuals due to a lack of clear symptoms.
- Researchers conducted a school-based survey in Beijing to create predictive models for MASLD and validated these models in Ningbo, comparing various statistical methods to determine the most effective approach for screening.
- The logistic regression model identified the waist-to-height ratio (WHtR) as the best non-invasive predictor for MASLD, and the combination of WHtR with lipid accumulation product (LAP) enhanced prediction accuracy.

- Long-term exposure to particulate matter (PM) is significantly associated with increased risks of depressive symptoms among students aged 10-25.
- Sleep duration and physical activity can help lessen these negative effects of PM on mental health.
- The study highlights the need for further research on causality due to its cross-sectional design, while emphasizing the importance of sufficient sleep and outdoor activity in combating mental health decline linked to air pollution.
Article Synopsis
- - The study measured indoor Light-At-Night (LAN) exposure levels among 897 children and adolescents (ages 6-14) in Beijing, finding that 31.8% had average exposure above 10 lux between 9 PM and 7 AM.
- - On average, participants experienced more than 64 minutes of exposure above 10 lux during the night, with higher levels recorded on weekends compared to school days.
- - Notably, girls and those in higher grades had greater exposure, particularly 7th-grade girls who showed the highest levels, highlighting the need for better light exposure habits to protect health.
Article Synopsis
- Light non-aqueous phase liquids (LNAPLs) contaminate subsurface areas, primarily categorized into source zones and plume zones, requiring clear differentiation for effective remediation strategies.
- This study utilizes the induced polarization (IP) method to analyze contaminants at a former chemical plant, identifying that the standard conductivity measurements alone are insufficient to distinguish between the source and plume zones.
- Significant differences in phase measurements and normalized chargeability help clarify these zones, suggesting that IP imaging enhances LNAPL site assessments and remediation efforts.
Background: The characteristics of scoliosis afflicting school children and adolescents in mainland China are still unclear. Therefore, we conducted a systematic review to estimate scoliosis's prevalence and characterise its distribution in China.
Methods: We screened PubMed, Scopus, WanFang, China National Knowledge Infrastructure, National Science and Technology Library, and WeiPu databases for mainland China articles published between 1 January 1980 and 31 October 2022.
Article Synopsis
- The study evaluates the trends of HIV/AIDS, gonorrhea, and syphilis among Chinese children and adolescents (6-22 years old) from 2013 to 2021, analyzing data from over 614,000 reported cases.
- While the spread of HIV/AIDS has stabilized, gonorrhea and syphilis cases have risen significantly, particularly among students aged 13-15, indicating a concerning public health trend.
- The research highlights that areas with less sexual health education have higher STI rates, and suggests that economic conditions also contribute to these disparities, pointing to a need for targeted public health strategies to address the issue.
Background And Objectives: This study aimed to examine the associations between breastfeeding duration and metabolic syndrome (MetS) in adolescents and to further investigate the role of birth weight for gestational age (GA) on these associations.
Methods: A total of 10 275 participants aged 7 to 18 years were included applying multistage cluster random sampling from a Chinese national survey. Birth weight was classified into small for GA (SGA), appropriate for GA (AGA) and large for GA (LGA).
Article Synopsis
- The study examines the impact of the COVID-19 pandemic on the incidence and mortality rates of 42 infectious diseases among children and adolescents in China, comparing these to levels before the pandemic.
- Utilizing the Notifiable Infectious Disease Surveillance System, researchers analyzed data from individuals aged 5-22 from 2018 to 2021, focusing on various categories of infectious diseases and their trends during different phases of the pandemic.
- Findings reveal a sharp decline in infectious disease cases during the pandemic year (2020) followed by a rebound in 2021, with notable differences between disease types and a consistent decrease in mortality over the four years studied.
Background: The urban-rural disparities in overweight and obesity among children and adolescents are narrowing, and there is a need for long-term and updated data to explain this inequality, understand the underlying mechanisms, and identify priority groups for interventions.
Methods: We analyzed data from seven rounds of the Chinese National Survey on Students Constitution and Health (CNSSCH) conducted from 1985 to 2019, focusing on school-age children and adolescents aged 7-18 years. Joinpoint regression was used to identify inflection points (indicating a change in the trend) in the prevalence of overweight and obesity during the study period, stratified by urban/rural areas and sex.
China is home to the second largest population of children and adolescents in the world. Yet demographic shifts mean that the government must manage the challenge of fewer children with the needs of an ageing population, while considering the delicate tension between economic growth and environmental sustainability. We mapped the health problems and risks of contemporary school-aged children and adolescents in China against current national health policies.

Limited research has been conducted to investigate the collective impact of outdoor time and other modifiable factors on the incidence of myopia.
What Is Added By This Report?: This study provides support for the protective effect of combining increased outdoor time with other prevention strategies in reducing the incidence of myopia.
Background: Overweight and obesity (OWOB) and myopia have become two of the most important issues affecting the health of children and adolescents worldwide. Despite the recognition that the school physical activity (PA) environment is a critical factor for preventing and controlling overweight, obesity (OWOB), and myopia in children and adolescents, research on OWOB and myopia as a comorbidity remains unexplored, with evidence for effective strategies still being inconclusive. Hence, this study aimed to assess the prevalence and progression of comorbid OWOB/myopia and each condition alone, and to explore the association with school PA environment.
