Associations of cold spells and heat waves with frailty trajectory among older adults: a longitudinal study from the JAGES Study.

Key Points

• To investigate how cold spells and heat waves contribute to the frailty trajectory in older adults.
• Longitudinal analysis using data from the JAGES Study
• Assessment of frailty over time
• Examination of temperature extremes and their impact
• Cold spells are associated with higher frailty worsening risk
• Heat waves also correlate with increased frailty in older adults
• Findings support the need for public health interventions during extreme temperatures
