Americans born in the 1960s and early 1970s are reporting higher levels of loneliness and depression than people from earlier generations. They are also showing declines in memory and physical strength. These patterns are unusual when compared with other wealthy nations. In many peer countries, especially in Nordic Europe, measures of midlife health and well-being have improved rather than worsened.
To better understand why the United States stands out, psychologist Frank J. Infurna of Arizona State University and his colleagues analyzed survey data from 17 countries. Their goal was to explain why trends in U.S. midlife health differ so sharply from those seen elsewhere.
"The real midlife crisis in America isn't about lifestyle choices or sports cars. It's about juggling work, finances, family, and health amid weakening social supports," Infurna said. "The data make this clear."
The findings were published in Current Directions in Psychological Science and suggest clear directions for change at both the personal and societal levels.
One major factor separating the U.S. from Europe is public support for families. Since the early 2000s, European countries have steadily increased spending on family benefits. In contrast, spending in the United States has remained mostly unchanged. The U.S. lacks many common family policy programs found in Europe, including cash transfers for families with children, income support during parental leave, and subsidized childcare.
These policy differences matter most during midlife, a period when many adults are balancing full-time work while raising children and supporting aging parents. In countries with stronger family benefits, middle-aged adults reported lower levels of loneliness and smaller increases in loneliness over time. In the United States, loneliness increased steadily across successive generations.
Health care affordability is another important piece of the puzzle. Although the United States spends more on health care than any other wealthy nations, access to care is often more limited and costs are higher for individuals. The authors noted that rising out-of-pocket expenses place added pressure on household budgets, reduce the use of preventive care, and contribute to stress, anxiety, and medical debt.
Income inequality also helps explain the widening gap between the U.S. and its peers. Since the early 2000s, inequality has increased in the United States, while it has stabilized or declined in most European countries. Infurna's research found that greater inequality is associated with worse health outcomes and higher levels of loneliness among middle-aged adults.
Other studies show that income inequality increases poverty, limits opportunities to move up the SES ladder, and restricts access to education, employment, and social services. Each of these barriers can have lasting effects on physical and mental health.
Cultural patterns may further widen international differences. Americans are more likely than people in other countries to move frequently and live far from extended family. These patterns can make it harder to maintain long-term social ties and dependable caregiving support.
At the same time, people from later U.S. birth cohorts have built less wealth and face greater financial insecurity than earlier generations. Wage stagnation and the lasting impact of the Great Recession have contributed to these vulnerabilities. In many European nations, stronger social safety nets appear to have helped protect middle-aged adults from similar health declines.
One of the most striking findings involves cognitive health. Despite rising levels of educational attainment, U.S. middle-aged adults showed declines in episodic memory -- a pattern not observed in most comparable countries.
"Education is becoming less protective against loneliness, memory decline, and depressive symptoms," Infurna said.
The researchers suggest that chronic stress, financial insecurity, and higher rates of cardiovascular risk factors may weaken the cognitive benefits that education once provided.
The authors emphasize that poorer midlife outcomes in the United States are not inevitable. Personal resources such as strong social support, a sense of control, and positive attitudes toward aging can help reduce stress and protect well-being. However, they argue that individual efforts alone are not enough.
"At the individual level, social engagement is crucial. Finding community -- through work, hobbies, or caregiving networks -- can buffer stress and improve well-being," Infurna said. "At the policy level, countries with stronger safety nets -- paid leave, childcare support, healthcare -- tend to have better outcomes."
