Participation in Social Activities and Relationship between Walking Habits and Disability Incidence

Abstract

Identifying the relationship between physical and social activity and disability among community-dwelling older adults may provide important information for implementing tailored interventions to prevent disability progression. The aim of this study was to determine the effect of the number of social activities on the relationship between walking habits and disability incidence in older adults. We included 2873 older adults (mean age, 73.1 years; SD, ±5.9 years) from the National Center for Geriatrics and Gerontology—Study of Geriatric Syndromes. Baseline measurements, including frequencies of physical and social activities, health conditions, physical function, cognitive function, metabolic parameters, and other potential disability risk factors (for example, the number of years of education); monthly assessment for disability was monitored through long-term care insurance certification for at least 2 years from baseline. During a mean follow-up of 35.1 months (SD, 6.4 months), 133 participants developed disability. The disability incidence was 19.0 and 27.9 per 1000 person-years for participants who walked more (≥3 times per week) and less (≤3 times per week) frequently, respectively. The potential confounding factor-adjusted disability hazard ratio was 0.67 (95% confidence interval, 0.46 to 0.96; p = 0.030). The relationship between habitual walking and the number of social activities was statistically significant (p = 0.004). The reduction of disability risk by walking was greater among participants with fewer social activities. Habitual walking was associated with disability incidence, with a more pronounced effect among older adults who were less likely to engage in social activities.

The Complexity of Social Networks in Healthy Aging: Novel Metrics and Their Associations with Psychological Well-Being

“…Dimension 2 (ego centrality or social integration) as Dimension 3 (strengths of contacts or social support) was only linked to the number of people living with ego. This last result is logical and has been found in many studies (Hsieh & Zhang, 2021;Katayama et al, 2021;Lowndes et al, 2021;Seeman & Berkman, 1988;Zainuddin et al, 2020), but we expected to observe other influences, such as those from income, population density, urban quality, and accessibility (Kim et al, 2018;Sharmeen et al, 2014). Wood et al (2010) for example, studied the association between sense of community, walking, and neighborhood design characteristics and found that the sense of community was enhanced by living in areas that encourage leisurely walking.…”

Psychological Effects of Motivational Aquatic Resistance Interval Training and Nutritional Education in Older Women

“…In relation to the present work, a previous study found that the perception of psychological well-being and the improvement of subjective health were also significantly related to regular and intensive physical exercise [ 52 ], another recent study indicates that daily physical activity has psycho-social benefits in the older adults and may lead to better outcomes in the primary prevention of disability [ 53 ]. The improvements reported by the experimental group coincide with those of other aquatic training programs developed in older adults, who also obtained improvements in functional autonomy [ 54 ], although in their case, they did not carry out psychological strategies.…”

Volunteer activity and the prevalence of long-term care/support needs among older Japanese people: a spatial error model

“…We believe the explanation for these findings is that both of these types of activities require physical exercise. Researchers found that walking was beneficial to older people's physical performance (Katayama et al, 2021;Wong et al, 2003), which could include decreasing their eventual need for long-term care/support.…”
