Altruistic behaviour, but not volunteering, has been associated with cognitive performance in community-dwelling older persons.

AIM

Studies have indicated that altruistic behaviour may be associated with better health. Nevertheless, it has not been determined if volunteering acts as a protective factor against cognitive decline or if a person's altruistic character does so. This study aims to evaluate whether altruistic behaviour and volunteering are associated with better cognitive function in active community-dwelling older persons.

METHODS

This was a cross-sectional study in healthy older persons. Sociodemographics, altruistic behaviour (self-report altruism scale), volunteering (days volunteered), cognitive state (cognitive assessment battery), and factors associated with cognition (e.g. depression, social support, functional status, and religiosity) were evaluated. Adjusted and non-adjusted models were created in order to understand the relationship of altruistic behaviour and volunteering with cognitive performance.

RESULTS

A total of 312 older adults were evaluated; 89.4% were women, and the mean age was 69.6 years. In the linear regression models, greater altruistic behaviour was associated with higher scores on the Mini-Mental State Examination (β = 0.148, P < 0.05) and the verbal fluency test (β = 0.219, P < 0.001), even after adjustments. In contrast, volunteering was not associated with any of the cognitive tests used.

CONCLUSION

Altruistic behaviour seems to have a role in older persons' cognition, with more altruistic people tending to have greater cognitive performance. These findings can assist in developing mechanisms that can help keep older people more cognitively active and serve as the foundation for future interventions and studies in this area.
