Sightlines

The Sightlines Project investigates how well Americans are doing in each of the three areas that are critical to well-being as people age: financial security, social engagement and healthy living. Do the trends over the last 15 years bode well or do they raise concerns regarding our capacity to thrive as individuals and as a nation?

The findings are based on analyses of eight nationally representative, high quality, multi-year studies over two decades involving more than 1.2 million Americans. The learnings are intended to stir national debate, guide policy development, stimulate entrepreneurial innovation, and encourage personal choices that enhance independent, 100-year lives.

KEY FINDINGS 
Healthy Living, defined as avoiding risky behaviors (smoking, excessive drinking, drug use, etc.) and making healthy choices day to day (eating well, exercising, etc.), is known to be beneficial. Americans have made substantial progress in several areas, while others challenges remain or have actually increased.

Most surprising:

  • Smoking –the top preventable cause of morbidity and early mortality – is declining in every age group.
  • For the first time in decades, more Americans are exercising regularly. More than half of Millennials (ages 25-34) are getting the recommended amount of exercise.
  • Sitting, which has emerged as an independent risk factor for health, is steeply increasing.
  • Problems with diet and sleep are widespread and show no signs of abating.

Financial security across the life span is a growing challenge for longer lives. Financial security has deteriorated from 2000 to 2014, particularly among the least educated, who are more likely to live at or near poverty, lack emergency resources, and are less likely to invest in their financial futures.

Most surprising:

  • A 15-year decline in health insurance coverage among the most vulnerable (those without high school education) has reversed since the implementation of the Affordable Care Act, decreasing the likelihood that the financial security of those in this group will be decimated by a health event.
  • Millennials (adults ages 25 to 34) are facing uphill struggles. The incomes of the less educated are often at or near poverty levels while those who went to college are 50% more likely to carry debt and the average debt in this group is 5 times higher than their predecessors carried just 15 years ago.
  • Fewer Americans (two out of three) establish retirement savings plans before age 55. Among those who are ineligible for employer-based plans, only one in three is participating in a plan.

Social engagement, central to long and healthy lives, includes both meaningful relationships and participation in communities. Social engagement is declining along many traditional indicators. It is too soon to tell whether new forms of technology-mediated social engagement – SMS, chat, facetime, posting and tweeting – are providing social benefits and how they complement face to face engagement.

Most surprising:

  • With the exception of 35-44 year olds, community engagement has declined. Interactions with neighbors – who represent physically-accessible and often helpful relationships – are becoming less common.
  • Compared to their counterparts only 20 years ago, members of the Baby Boom generation, are less likely to be married, have weaker ties to family, friends, and neighbors, and are less likely to engage in religious or community activities.
  • Longer lives mean that marriages survive as well. Fifty-three percent of Americans over 75 are married, up from 42 percent in 2003.

People worldwide are living longer

In September 2015, the World Health Organization (WHO) put out a fact sheet to describe ageing and health. 

“In accordance with a recent World Health Resolution (67/13), a comprehensive Global Strategy and Action Plan on Ageing and Health is being developed by WHO in consultation with Member States and other partners. The Strategy and Action Plan draws on the evidence of the World report on ageing and health and builds on existing activities to address 5 priority areas for action.”

  • Commitment to Healthy Ageing. Requires awareness of the value of Healthy Ageing and sustained commitment and action to formulate evidence-based policies that strengthen the abilities of older persons.
  • Aligning health systems with the needs of older populations. Health systems need to be better organized around older people’s needs and preferences, designed to enhance older peoples intrinsic capacity, and integrated across settings and care providers. Actions in this area are closely aligned with other work across the Organization to strengthen universal health care and people-centred and integrated health services.
  • Developing systems for providing long-term care.Systems of long-term care are needed in all countries to meet the needs of older people. This requires developing, sometimes from nothing, governance systems, infrastructure and workforce capacity. WHO’s work on long-term care (including palliative care) aligns closely with efforts to enhance universal health coverage, address non-communicable diseases, and develop people-centred and integrated health services.
  • Creating age-friendly environments. This will require actions to combat ageism, enable autonomy and support Healthy Ageing in all policies and at all levels of government. These activities build on and complement WHO’s work during the past decade to develop age-friendly cities and communities including the development of the Global Network of Age Friendly Cities and Communities and an interactive information sharing platform Age-friendly World. 
  • Improving measurement, monitoring and understanding. Focused research, new metrics and analytical methods are needed for a wide range of ageing issues. This work builds on the extensive work WHO has done in improving health statistics and information, for example through the WHO Study on global AGEing and adult health (SAGE).

Dietary restriction and nutrient balance

According to a recent review … “not only is long-term food restriction is not feasible for most people, but may also reduce reproductive function and increase the risk of osteoporotic bone fractures and cardiac arrhythmias. To overcome this low compliance to food dietary restriction (DR), a promising strategy is to use DR mimetics, by the development of pharmaceutical compounds that lead to the same physiological effects as DR without significantly reducing food intake. The best studied

DR mimetics are rapamycin, metformin, and resveratrol, which have shown anticancer properties and consequently are being tested in clinical trials.
Intermittent fasting (IF) involves restriction of energy intake for periods of 1-2 days a week with no restriction during feeding periods whereas
periodic fasting (PF) involves fasting for 3 or more days every 2 or more weeks, also with no restriction during feeding periods. Fasting for a period of 2 or 5 days is known to promote a 50% reduction in glucose and IGF-1 levels in both mice and humans, respectively, and to promote depletion
of hepatic glycogen, leading to the generation of ketone bodies. In cancer treatment, fasting has shown to have more consistent positive effects than DR. Fasting generates an extreme environment that induces protective changes in normal cells, but not in cancer cells, that fail to respond to the protective signals of fasting due to the role of oncogenes as
negative regulators of stress resistance.”

Treating ageing

There’s a commentary article on Nature about treating ageing. Read it here.

“By 2050, the number of people over the age of 80 will triple globally. These demographics could come at great cost to individuals and economies. Two groups describe how research in animals and humans should be refocused to find ways to delay the onset of frailty.

early humans (Homo heidelbergensis) cared for the elderly

Andy Coghlan reported recently on the New Scientist about the mounting set of evidence that the Homo heidelbergensis group of hunter-gatherers cared for the weak elderly in their group. This species lived about 500,00 years ago. Studies on bone remnants of an individual called “Elvis” indicated that he could have been cared for by his younger contemporaries. He was 45 when he died.

“The presence of degenerative pathological lesions and the advanced age-at-death of this individual make it the most ancient postcranial evidence of an aged individual in the human fossil record.”

how old was he

I overheard this conversation today, about a person who died recently:

Lady 1: How old was he?

Lady 2: 63

Lady 1: Oh I see. I would have been surprised if he was in his 40s or younger.

It struck me that there seems to exist a notion that older people have more reason to die than younger people. Why is that? Why can’t we think that anybody, regardless of age, has the same chance of dying anytime anywhere as anyone else? I thought this might have something to do with how people perceive old age. Despair appears to dominate the experience of getting older. It is like waiting for your own self-destruction … is it really?
