Relationship of Hobby Activities With Mortality and Frailty Among Community-Dwelling Elderly Adults: Results of a Follow-up Study in Japan

Abstract

BackgroundThe proportion of Japanese adults aged 65 years or older is predicted to increase; thus, it is becoming more important to identify factors that influence health status among elderly adults in Japan. We conducted a follow-up study of community-dwelling elderly adults to assess the relationship of hobby activities with mortality and incident frailty.MethodsWe randomly selected 3583 individuals aged 65 to 84 years from the residential registries of 7 study areas in Hokkaido, Japan in August 2007. Among them, 1955 (54.6%) returned completed questionnaires with written informed consent by mail. The baseline assessment questionnaire comprised questions on current and past involvement in hobby activities, self-perceived health status, smoking and drinking habits, and body height and weight. Questions on hobby activities were from 4 categories: solitary physical, group physical, solitary cultural, and group cultural activities. We later conducted a follow-up survey of the participants to ascertain all-cause mortality and incident frailty. A Cox proportional hazards model was used for analysis of data from September 2007 to May 2010.ResultsAfter adjusting for potential confounders, the risk of incident frailty among respondents participating in solitary physical activities was significantly lower than in those who did not participate in such activities (hazard ratio = 0.57; 95% CI 0.33, 0.99). Furthermore, the risk of incident frailty among respondents taking part in group cultural activities was significantly lower than in those who did not participate in such activities (0.41; 0.19, 0.87).ConclusionsThese findings may be important for programs that seek to promote good health among elderly adults.

Physical Frailty and Its Associated Factors Among Elderly Nursing Home Residents in China

“…One explanation is that there is a vicious cycle: due to the fear of falling [36], as the level of frailty increases, so does the tendency to avoid taking regular exercise. Participants with frailty had poorer self-reported health in our study, in concordance with results from previous studies [12,37,38]. This might be explained that frail older people have a state of greater vulnerability [39], so they were more likely to rate their health poorly.…”

Community activities predict disability and mortality in community‐dwelling older adults

“…Some studies have described that periodic physical exercise or group culture activities reduced the risk of frailty and/or mortality . In contrast to these studies, we defined hobbies and favorite lessons as any activity – physical or cultural – carried out once a week or more in individual or group units.…”

This was because we thought it important to consider older adults' feelings of comfort and joy in pursuing their preferred activities.…”

Screening for frailty phenotype with objectively-measured physical activity in a west Japanese suburban community: evidence from the Sasaguri Genkimon Study

“…Older adults who engaged in social activities were less likely to become frail. Frequent engagement in social activities could help to maintain physical and mental fitness [ 41 ] and then compensate for age-related decline in reserve and function. Another explanation is that withdrawal from social activities could be a behavioral precursor of frailty.…”
