Wcn26-176 Association Between Ambient Temperature Extremes and Acute Kidney Injury Hospitalizations in Japan: A Nationwide Time-Stratified Case-Crossover Study, 2011–2019

Key Points

• The study investigates how extreme ambient temperatures affect acute kidney injury hospitalizations, with a focus on demographic differences.
• Analyzed nationwide data of AKI hospitalizations from 2011 to 2019
• Used a case-crossover design to compare hospitalization rates during temperature extremes to baseline temperatures
• Examined differences based on age and sex
• Increased hospitalizations for AKI were linked to extreme heat and cold temperatures
• Demographic factors, such as age and sex, influenced the susceptibility to temperature-related AKI
• Findings highlight the risk of AKI during temperature extremes, indicating a public health concern
