Does Laughter Predict Onset of Functional Disability and Mortality Among Older Japanese Adults? The JAGES Prospective Cohort Study
- The link between laughter and functional disability and all-cause mortality was prospectively studied in community-dwelling Japanese older adults.
- After adjustment for 13 potential confounders, low frequency of laughter was associated with increased risks of functional disability.
- The inverse association between the frequency of laughter and the risk of all-cause mortality was insignificant after adjusting for all covariates.
- Frequency of laughter is potentially considered an early indicator of functional disability later on in life.
