Effects of sub- and supraoptimal indoor temperatures on kidney injury in home-bound frail elderly patients: A pilot case-crossover study
Key Points
To investigate how suboptimal and supraoptimal indoor temperatures affect kidney injury in frail elderly individuals.
Pilot case-crossover design conducted in home-bound frail older adults
Assessment of indoor temperature exposure and renal function
Monitoring for indicators of renal stress
Suboptimal temperatures correlated with increased kidney injury markers
Supraoptimal temperatures showed potential for worsening kidney function
Emphasized the need for adaptive strategies to reduce climate-related risks
Abstract
Suboptimal indoor temperatures may trigger subclinical renal functional stress in frail older adults. Monitoring and adaptive strategies are necessary to mitigate risks associated with climate change.
