Abstract

There is scant research on the association between humidex exposure and urinary system diseases. Hospitalization records from Lanzhou city were collected for the period 2015 to 2019, alongside daily meteorological and air pollution data for the study duration. Daily humidex was calculated using temperature and relative humidity indices. The study employed a combined approach of generalized additive models and distributed lag non-linear models (DLNMs) to estimate the exposure-lag-response relationship between humidex and hospital admissions for urinary system diseases, as well as for subgroups of diseases (urolithiasis and tubule-interstitial diseases). A total of 55,365 patients with urinary system diseases were included. The single lag effect of overall urinary system diseases was most significant on lag13 with the relative risk (RR) = 1.066 (95% confidence interval [CI]: 1.011, 1.124), while the cumulative lag effect over lag0–14 was most significant with RR = 1.387 (95% CI: 1.240, 1.550). The goal of this study was to establish an early warning system and allocate medical resources effectively to reduce hospital admissions for urinary system diseases.

期刊介绍： Science has many big remaining questions. To address them, we will need to work collaboratively and across disciplines. The goal of iScience is to help fuel that type of interdisciplinary thinking. iScience is a new open-access journal from Cell Press that provides a platform for original research in the life, physical, and earth sciences. The primary criterion for publication in iScience is a significant contribution to a relevant field combined with robust results and underlying methodology. The advances appearing in iScience include both fundamental and applied investigations across this interdisciplinary range of topic areas. To support transparency in scientific investigation, we are happy to consider replication studies and papers that describe negative results. We know you want your work to be published quickly and to be widely visible within your community and beyond. With the strong international reputation of Cell Press behind it, publication in iScience will help your work garner the attention and recognition it merits. Like all Cell Press journals, iScience prioritizes rapid publication. Our editorial team pays special attention to high-quality author service and to efficient, clear-cut decisions based on the information available within the manuscript. iScience taps into the expertise across Cell Press journals and selected partners to inform our editorial decisions and help publish your science in a timely and seamless way.
