Why Is Life Expectancy Dropping?

I always wonder about the recent trend of life expectancy dropping in countries like the U.S. A couple of new studies show the decline has continued:

(Reuters Health) – Life expectancy is declining in high-income countries worldwide, driven in part by the effects of the opioid epidemic on younger adults in the U.S. and the impact of a severe flu season on older adults in other nations, two new studies suggest.

Life expectancy is a measure of the health and wellbeing of a population. Widespread or sustained declines in life expectancy may signal problems in a nation’s social and economic conditions or in the provision or quality of its healthcare services, researchers write in The BMJ.

The first study looked at trends across 18 high-income countries and found that most countries experienced declines in life expectancy in 2015. This is the first time in recent decades that so many high-income countries simultaneously experienced declines in life expectancy for both men and women.

Out of 18 countries in the study, 12 experienced life expectancy declines among men and 11 experienced life expectancy declines among women.

“This hasn’t occurred in decades, and the size of these most recent declines were larger than prior declines,” said study co-author Jessica Ho of the University of Southern California in Los Angeles. …

In the U.S., the source of reduced life-expectancy was concentrated at younger ages, particularly deaths among those in their 20s and 30s, and largely driven by increases in drug-overdose deaths related to the nation’s ongoing opioid epidemic.

A second study in The BMJ suggests, however, that the problems driving life expectancy declines in the U.S. are broader than just the opioid crisis and may extend to a wide range of causes unrelated to drug use or substance abuse. ..

Even worse, the study found rising midlife death rates from dozens of diseases of the heart, lungs, digestive systems and other organs. It even found rising death rates during pregnancy and early childhood, Woolf said.

“Something far-reaching is affecting the health of Americans in the prime of their lives,” Woolf said.

Neither study was a controlled experiment designed to prove what specific factors might be influencing declines in health or life expectancy in the U.S. and other countries.

Still, taken together, these studies highlight a need for high-income countries to invest more in preventing disease outbreaks and addressing persistent social and health inequalities, said Domantas Jasilionis of the Max Planck Institute for Demographic Research in Rostock, Germany.

“Although a part of this health disadvantage of lower socioeconomic classes is explained by ‘traditional’ risk factors such as poor diet, alcohol and smoking, the question remains why these people have a higher risk of choosing such health damaging behaviors,” Jasilionis, author of an editorial accompanying the studies, said by email.

“There is strong evidence that psychological factors, often having social origins including social exclusion, poor prospects for social mobility, and high income inequality are the main contributors to these ‘bad choices,’ especially in the lowest socioeconomic groups,” Jasilionis added.

What concerns me about such studies is that the researchers seem to want the focus to be on “social exclusion” and income inequality and one has to wonder how this will translate into public policy. Instead of taking a problem-solving approach to understanding why people make poor choices, my guess is that policy makers and liberals will see the decline in life expectancy as a reason to make more laws and policies that take from high-income groups to give to lower-income ones or to those they deem to be “socially excluded.”

This will only result in more money in politicians’ pockets and no more solutions since bad choices do not go away when you throw money at them. People have to be taught not to make bad choices but this takes a lot of work and discipline, something in short supply these days.
