Insights
The prevalence of allergic rhinitis in Chinese children is 18.46%, with higher rates observed in recent years (2012-2021) and in specific regions and demographics. This study provides crucial data for understanding and managing allergic rhinitis in children.
Area of Science:
- Pediatric Allergy and Immunology
- Epidemiology
- Public Health
Background:
- Allergic rhinitis is a common condition affecting children globally.
- Understanding the epidemiological trends of allergic rhinitis in China is crucial for public health initiatives.
- Previous data on the prevalence of allergic rhinitis in Chinese children over a two-decade period is limited.
Purpose of the Study:
- To determine the prevalence of allergic rhinitis in Chinese children from 2001 to 2021.
- To analyze trends and variations in prevalence based on publication year, geographical region, sex, and ethnicity.
- To provide essential data for the prevention and treatment strategies for allergic rhinitis in pediatric populations.
Main Methods:
- Systematic literature search of multiple databases (CNKI, CBM, VIP, WanFang Data, PubMed, Web of Science, Embase, Cochrane Library) for studies published between 2001 and 2021.
- Inclusion of 20 cross-sectional studies encompassing 54,886 children and adolescents.
- Meta-analysis performed using Stata 16.0, with subgroup analyses conducted for temporal, regional, sex, and ethnic variations.
Main Results:
- The overall prevalence of allergic rhinitis among Chinese children was found to be 18.46%.
- Prevalence increased significantly from 14.81% (2001-2011) to 19.75% (2012-2021).
- Significant regional variations were observed, with East China showing the highest prevalence (22.77%). Males (20.73%) had a higher prevalence than females (16.34%), and Han Chinese (17.31%) had higher prevalence than ethnic minorities (15.93%).
Conclusions:
- Allergic rhinitis is highly prevalent in Chinese children.
- The prevalence of allergic rhinitis in this population has shown an increasing trend.
- Significant disparities in prevalence exist across different regions, sexes, and ethnic groups, necessitating targeted interventions.
Abstract:
Objective: To analyze the prevalence of allergic rhinitis in Chinese children from 2001 to 2021, in order to provide data support for the prevention and treatment of allergic rhinitis in children. Methods: "Allergic rhinitis" "children" "adolescent" "infant" "prevalence" "epidemiology" were used in the main search terms. The combination of Mesh words and free words was adopted. CNKI, CBM, VIP, WanFang Data, PubMed, Web of Science, Embase and The Cochrane Library for publications between January 1, 2001 and December 31, 2021 were searched systemically and data were extracted from eligible studies by two independent reviewers. Supplementary collection was made by identifying retrospective references from the included literature. After study quality assessment, Meta analysis was completed using Stata 16.0 software. Results: A total of 20 cross-sectional studies were included, involving 54 886 cases. Meta analysis results showed that the overall prevalence of allergic rhinitis among the participants was 18.46% (95%CI:14.34%-22.59%). Subgroup analysis showed that the prevalence of allergic rhinitis from 2012 to 2021 (19.75%) was higher than that from 2001 to 2011 (14.81%), and the difference was statistically significant (P<0.001). The prevalence of different regions from high to low was East China (22.77%), North China (20.82%), Northwest China (17.77%), Central China (16.62%), Southwest China (16.33%), Northeast China (16.16%) and South China (7.29%) respectively, the difference was statistically significant (P<0.001). The prevalence of male (20.73%) was higher than that of female (16.34%), and the difference was statistically significant (P<0.001). The prevalence of Han nationality(17.31%) was higher than that of ethnic minorities (15.93%), and the difference was statistically significant (P<0.001). Conclusion: The prevalence of allergic rhinitis in Chinese children is high and the prevalence in children varies by publication year, region, sex and nationality.

Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
