Editor’s note: It makes sense that wealth is linked to or promote longevity. A few things that come with wealth are in favor of longevity.
  • The living condition of rich people is better than that of poor people.  Some living conditions are not good for health.
  • Rich people tend to be smarter and they know better how to manage their health conditions when they occur.  They also have more resources to use to help correct their health conditions.
  • They do not have to subject themselves to stressful/laborious working conditions.  Labor work requires laborers to use high intake of calories which is one major factor that speeds up the aging process.
  • Rich people do not have to worry about their finance.  Mental stress is another main factor that causes health conditions like cancer and heart disease.

編者按:財富與長壽有關或促進長壽是有道理的。 財富帶來的一些東西有利於長壽。

  • 富人的生活條件比窮人好。 有些生活條件不利於健康。
  • 富人往往更聰明,他們更知道如何在健康狀況發生時進行管理。 他們還有更多資源可用於幫助糾正他們的健康狀況。
  • 他們不必讓自己承受壓力/辛苦的工作條件。 勞動工作要求勞動者消耗大量卡路里,這是加速衰老過程的主要因素之一。
  • 富人不必擔心他們的財務。 精神壓力是導致癌症和心髒病等健康狀況的另一個主要因素。

Study finds evidence that association between wealth and longevity persists even within siblings and twin pairs

Northwestern University

EVANSTON, Ill., — One of the keys to a long life may lie in your net worth.

In the first wealth and longevity study to incorporate siblings and twin pair data, researchers from Northwestern University analyzed the midlife net worth of adults (mean age 46.7 years) and their mortality rates 24 years later. They discovered those with greater wealth at midlife tended to live longer.

The researchers used data from the Midlife in the United States (MIDUS) project, a longitudinal study on aging. Using data from the first collection wave in 1994-1996 through a censor date of 2018, the researchers used survival models to analyze the association between net worth and longevity.

To tease apart factors of genetics and wealth, the full sample was segmented into subsets of siblings and twins.

In the full sample of 5,400 adults, higher net worth was associated with lower mortality risk. Within the data set of siblings and twin pairs (n=2,490), they discovered a similar association with a tendency for the sibling or twin with more wealth to live longer than their co-sibling/twin with less. This finding suggests the wealth-longevity connection may be causal, and isn’t simply a reflection of heritable traits or early experiences that cluster in families.

“The within-family association provides strong evidence that an association between wealth accumulation and life expectancy exists, because comparing siblings within the same family to each other controls for all of the life experience and biology that they share,” said corresponding author Eric Finegood, a postdoctoral fellow in the Institute for Policy Research at Northwestern.

The researchers also considered the possibility that previous health conditions, such as heart disease or cancer, could impact an individual’s ability to accrue wealth due to activity limitations or healthcare costs — possibly confounding any association between wealth and longevity. To address this, they re-analyzed the data using only individuals without cancer or heart disease. However, even within this sub-group of healthy individuals, the within-family association between wealth and longevity remained.

The study’s senior author is Greg Miller, the Louis W. Menk Professor of Psychology and faculty fellow at the Institute for Policy Research at Northwestern. Co-authors of the study include other Northwestern faculty and trainees (Edith Chen, Daniel Mroczek, Alexa Freedman) as well as researchers from the University of Illinois, Urbana-Champaign; West Virginia University; Purdue University; and the University of Minnesota.

“Far too many American families are living paycheck to paycheck with little to no financial savings to draw on in times of need, said Miller. “At the same time, wealth inequality has skyrocketed. Our results suggest that building wealth is important for health at the individual level, even after accounting for where one starts out in life. So, from a public health perspective, policies that support and protect individuals’ ability to achieve financial security are needed.”


The study, “Association of Wealth and Longevity in US Adults at Midlife,” will be published in JAMA Health Forum at 11 a.m. (E.D.T.) on July 23.
