Abstract

Objective: This study evaluated temperature's lagged effects on urticaria outpatient visits in Nanchang, China (2017-2022), and identified sensitive populations through age/gender stratification.

Methods: Using a distributed lag nonlinear model (DLNM), we analyzed 71,779 urticaria visits, adjusting for humidity, weekday, holidays, and seasonal/long-term trends. Temperature effects (cold: 5th/25th percentiles; hot: 75th/95th percentiles) were compared to the 50th percentile.

Results: Temperature exhibited non-linear and delayed impacts. Daily averages >19.9°C initially increased then decreased urticaria risk, peaking at 29°C with a 15-day lag (RR=1.74, 95% CI:1.63-1.86). No adverse effects occurred below 19.9°C. Individuals aged ≥60 were most vulnerable: at 29°C with a 16-day lag, RR surged to 2.31 (95% CI:1.99-2.70).

Conclusion: Hot increases urticaria outpatient visits, while cold reduces risk. These findings highlight temperature-specific prevention strategies, particularly for older adults.

期刊介绍： International Journal of Environmental Health Research ( IJEHR ) is devoted to the rapid publication of research in environmental health, acting as a link between the diverse research communities and practitioners in environmental health. Published articles encompass original research papers, technical notes and review articles. IJEHR publishes articles on all aspects of the interaction between the environment and human health. This interaction can broadly be divided into three areas: the natural environment and health – health implications and monitoring of air, water and soil pollutants and pollution and health improvements and air, water and soil quality standards; the built environment and health – occupational health and safety, exposure limits, monitoring and control of pollutants in the workplace, and standards of health; and communicable diseases – disease spread, control and prevention, food hygiene and control, and health aspects of rodents and insects. IJEHR is published in association with the International Federation of Environmental Health and includes news from the Federation of international meetings, courses and environmental health issues.
