Longevity Research

Asset 6

Don’t dwell on the latest anti-aging article that your cousin posted on Facebook. There is real research out there about things you can do to help you live longer. And you don’t need to fast all day, go in an isolation tank or take tons of supplements. 

Research shows that people who engage in meaningful activities and forge strong connections with other people live happier, healthier and longer lives. Below is a sample of the research we think is particularly relevant.

Health Benefits of Engaging In Meaningful Activity


 

Civic Engagement as a Retirement Role for Aging Americans (2008)

Iowa study finding that “engaged retirees” who volunteered or took a paid job tied to civic engagement were more educated, in better health, and more physically active than other retirees.

Study of retirees in the U.S. reinforces other studies that show that people who are engaged in certain activities (paid work, formal volunteering, informal volunteering) are more likely to be satisfied than those not engaged in these activities. The study also highlights the negative impact of caregiving on life satisfaction, when caregiving is the sole focus or when caregivers are providing care for more than one family member.

 

Life Course Trajectories of Later-Life Cognitive Functions: Does Social Engagement in Old Age Matter? (2017)

Study using 12 years of data finds that increases in social engagement over time were associated with higher degrees of cognitive health. In contrast, when older individuals experienced a reduced social network and became less engaged with neighbors in their community, they were more likely to have declining cognitive functioning.  Also the study found that volunteering is a protective factor in cognitive decline. Individuals who volunteered were, over time, more likely to belong to the least vulnerable (i.e. the healthiest) groups. In contrast, when older individuals stopped volunteering, they were more likely to experience declining health.

 

The Meaningful Activity Participation Assessment: A Measure of Engagement in Personally Valued Activities (2010)

Study of older Los Angeles residents which used several surveys, including the “Meaningful Activity Participation Assessment” (MAPA) survey, where people indicated their participation in and the degree of personal meaningfulness they felt while doing 28 different activities.  The study supports prior research linking activity such as volunteering or engagement in work with purpose in life. In addition, the study suggests that participating in activities having greater personal significance may have more influence upon well being and quality of life than participation in a greater number activities that are less personally significant.

PhD dissertation undertaking an in-depth review of the research on meaningful activity and how it influences health and well-being as we age.  The paper addresses the development and validation of the Meaningful Activity Participation Assessment (MAPA), concluding that the MAPA survey is a reliable and valid measure of meaningful activity participation.

 

How Can We Not ‘Lose It’ if We Still Don’t Understand How to ‘Use It’? Unanswered Questions about the Influence of Activity Participation on Cognitive Performance in Older Age – A Mini-Review (2009)

Source: karger.com (Originally published in Gerontology)

Survey of research regarding the “use it or lose it” hypothesis of cognitive aging-which posits that engagement in physical, social, and intellectual activities in older adulthood prevents the deterioration of cognitive abilities.  This is also called the “engagement hypothesis.” This paper describes the research in this area and also suggests areas where new research should be done to further understand the relationship between activity participation and cognition.

 

Bowling Alone: The Collapse and Revival of American Community (2000)

Civic engagement has fallen dramatically over the last generation.  More Americans are bowling today than ever before, but bowling in organized leagues has plummeted. Virtually all leisure activities that involve doing something with someone else are declining.  Some reasons for this decline include changes in family structure, suburban sprawl, electronic entertainment, and generational change.

 

Feeling How Old I Am: Subjective Age Is Associated With Estimated Brain Age (2018)

Korean study finding that people who had a younger “Subjective Age” (i.e. felt younger than their actual age) were more likely to score higher on a memory test, considered their health to be better and were less likely to report depressive symptoms. In addition, those who felt younger than their age showed structural characteristics of a younger brain on MRI tests.

 

Risks of Isolation

Stanford study measures several areas critical to how people age well.   Among the conclusions: Socially isolated people face health risks comparable to those of smokers.  And their mortality risk is two times greater than that of obese people. In addition, 55-64 year olds are less likely to be socially engaged than people of that age in previous generations.  Research consistently indicates that volunteering confers mental and physical benefits—but just over 1 in 4 of us volunteers.

U.S. study shows that feeling useful to others as we age is critical.  Study shows that a persistently high level of feeling useful to others is associated with a significantly lower risk of mortality.

 

Social Relationships and Mortality Risk: A Meta-analytic Review (2010)

Data from 148 studies with a total of over 300,000 people followed for an average of 7.5 years, indicate that people with good social relationships have a 50% reduced risk of early death compared to those with poor social relationships, an effect similar to quitting smoking.

70 studies representing more than 3.4 million people primarily from North America but also from Europe, Asia and Australia, examined the role that social isolation, loneliness or living alone might have on mortality. Researchers found that all three had a significant and equal effect on the risk of premature death, one that was equal to or exceeded the effect of other well-accepted risk factors such as obesity.

 

Importance of Social Networks

Study found that older adults that learned how to use a social networking website showed a significant increase in certain executive function and memory tasks, compared to no significant change in the control group.

 

The Limits of Friendship (2014)

Anthropologist Dunbar believes that people can only have about 150 people in their social networks, their “Dunbar Number,” which is actually a layered series of numbers.  150 is the number of people we call casual friends, 50 is the number of close friends, 15 are in our inner circle, and your close support group is about five people. Researchers have found that despite the fact that some people may have many more “friends” online, social networking sites don’t really change these numbers.

Study of billions of phone calls by 35 million people shows good evidence for the existence of the innermost and outermost layers of networks that Dunbar describes.

 

Benefits of Volunteering

Irish study discussing that the positive association between volunteer work and well-being is widely documented.  Volunteer work leads to better self-reported health, higher life satisfaction and decreased rates of depression. The lowest quality of life is found for people who never volunteer, regardless of age group.  This positive association is also seen for people who have greater social engagement.

Belgian study finding that older adults who volunteered are also active in other activities, especially in civic activities. However, people who helped others informally, such as taking care of children or a sick person, had a decreased propensity to volunteer.

Among older adults, a higher degree of positive well-being is associated with having multiple roles instead of just one.  (e.g. caregiver, employee, volunteer, etc.).

UK program trained retired arthritis sufferers to teach an arthritis self-management course to others.  The lay leaders reported more confidence, happiness, and a changed outlook on life in general. Volunteers enjoyed helping others and being involved in a worthwhile activity, and they valued their newly acquired status as leaders.
