Americans who are wealthier at midlife tend to live longer than their less-wealthy peers — including peers who also happen to be their siblings, according to a new study published Friday in JAMA Health Forum.

Between the lines: The study suggests that the association between wealth and longevity isn't an artifact of early life experiences or genetics.

  • Even among twins, greater wealth correlated with a greater chance of survival later in life.

The big picture: The wealth gap between high-income and low-income Americans is large and growing.

What they're saying: "Policies that support individuals' ability to accrue wealth and achieve financial security could have considerable health benefits," the authors conclude.

  • "In addition, policies to reduce the wealth gap may generate substantial returns to public health."
