Different Levels of Leisure Walking and Mental Health Among Older Adults With Mild Cognitive Impairment.

Leisure walking has been found to be positively associated with increased mental health. However, the benefits of leisure walking of varying intensities on the mental health of older adults (>50 years old) with mild cognitive impairment are not clear. This study employed 2020 Health and Retirement Study data to investigate the benefits of leisure walking for three groups based on levels of participation (low, mid, and high). We conducted a multivariate analysis of covariance (n = 834) to examine the group mean differences (MDs). The respondents in the high and mid groups presented higher life satisfaction and happiness than those in the low group. The high group had lower loneliness and stress scores than those in the low and mid groups. These findings indicate that older adults with mild cognitive impairment gained more mental health benefits and life satisfaction through moderate and vigorous leisure walking than through light leisure walking.
