Not Even America's Richest Live as Long as Some of Europe's Poorest
New research shows a significant gap in mortality rates between the US and Europe, with even the wealthiest Americans more likely to meet an early death than the wealthiest Europeans – and in some cases, more likely than the poorest in some European countries too.
While having more money was unsurprisingly associated with lower mortality risk (and therefore longer life) in both the US and Europe, according to the stats, the disparity in survival rates between the richest and poorest populations was much stronger in the US.
These results could be explained by Europeans having greater access to healthcare and social welfare, and having stronger social structures than those in the United States, according to the international team of researchers behind the study.
"The findings are a stark reminder that even the wealthiest Americans are not shielded from the systemic issues in the US contributing to lower life expectancy, such as economic inequality or risk factors like stress, diet or environmental hazards," says health economist Irene Papanicolas, from Brown University in Rhode Island.
The researchers crunched the numbers on health and retirement records for 73,838 adults, aged between 50 and 85, across the years 2010 to 2022. For both the US and Europe, the participants were split into four groups (quartiles), from the most to the least wealthy.
The team looked at the chances of each group dying over the study period, which gives us a strong indication of the health and life expectancy of the participants. For each quartile, matching the US against Europe, Americans fared worse.
Mortality rates varied across European regions, but in Germany, France, and the Netherlands, even the poorest groups were shown to be doing better than the richest Americans in terms of how many people died during the study period.
Overall, across both regions, the wealthiest individuals were 40 percent less likely to die than the poorest. For all four wealth quartiles combined, rates of death were 40 percent lower in northern and western Europe than in the US.
"We found that where you stand in your country's wealth distribution matters for your longevity, and where you stand in your country compared to where others stand in theirs matters, too," says health economist Sara Machado, from Brown University.
"Fixing health outcomes is not just a challenge for the most vulnerable – even those in the top quartile of wealth are affected."
The benefits that wealth has on health are well documented – a higher income gives you access to everything from better food to better living conditions to better healthcare – but these findings show the disparities between regions as well as between income levels.
"If we want to improve health in the US, we need to better understand the underlying factors that contribute to these differences – particularly amongst similar socioeconomic groups – and why they translate to different health outcomes across nations," says Papanicolas.
The research has been published in the New England Journal of Medicine.

The 1 Thing That Food Experts Never Eat Or Drink While Traveling Abroad
When you're traveling abroad, you probably have a long list of must-sees and must-dos. Diarrhea, vomiting, and stomach cramps most definitely aren't on that list, but these digestive problems can be all too common. The Centers for Disease Control and Prevention estimates that 30% to 70% of vacationers get traveler's diarrhea, depending on where and when they go. The illness can often (but not always) be prevented by paying close attention to what you eat or drink, and by following the 'boil it, cook it, peel it or forget it' rule. 'Foodborne infections can strike at any time,' Leah Silberman, a registered dietitian with Medical Offices of Manhattan, told HuffPost. 'Traveling exposes you to new food sources, local food handling procedures, and different cleanliness standards. This raises your chances of coming into contact with infections or pollutants, against which your body may not have built protection.' Foods may also be contaminated with unsafe drinking water, or when handwashing isn't the norm or isn't done properly, said Mitzi Baum, CEO of the nonprofit Stop Foodborne Illness. Before traveling, it's a good idea to check the CDC's list of destinations, which highlights food or water safety issues, Baum said. Keep in mind, though, that you can get sick anywhere, including the US. About one in six Americans contract foodborne illness each year, which results in 3,000 deaths and 128,000 hospitalizations, according to the CDC. Travel enhances your risk of getting digestive issues, however. Along with not being acclimated to the foods or encountering different food-handling processes, jet lag and changes in climate can weaken your immune system, Silberman explained. Next time you travel, follow these tips for protecting yourself from traveler's diarrhea. Dietitians and food safety experts explain which foods are more likely to put you at risk for foodborne illness. What Is Traveler's Sickness? Traveler's diarrhea is the most common travel-related illness, and you get it by consuming tainted foods or drinks, according to the CDC. E. coli bacteria is the main culprit, Baum said, but travelers can also get sick from salmonella, shigella, or campylobacter. Viruses, like astrovirus, norovirus, and rotavirus, can also be to blame, as well as the parasite giardia. It often happens in instances of poor food handling, a lack of sanitation, or contaminated drinking water, Silberman said. Diarrhea, abdominal pain, cramping, nausea, vomiting, and fever are the most common symptoms of traveler's diarrhea, according to the Cleveland Clinic. Symptoms of viral or bacterial infections typically show up within six to 24 hours, but parasites can take a few weeks to show signs. The highest-risk destinations are Asia (except for Japan and South Korea), the Middle East, Africa, Mexico, and Central and South America, according to the CDC. Washing your hands frequently with soap and water, especially after using the bathroom and before eating, can reduce your risk, Baum said. Foods And Drinks To Avoid When Traveling Abroad You can actually get foodborne illness from any food or beverage. But some might be riskier than others, depending on where you travel. Food safety measures, sanitary standards, and culinary habits vary in different parts of the world, Silberman said. Your best bet is to research food safety and health risks for your destination. But here are some foods and drinks to consider avoiding. Raw fish and meat Raw meat and seafood are a 'big no-no,' according to Vanessa Rissetto, a registered dietitian and co-founder and CEO of Culina Health. 'We can't source where they came from, how long they've been out, and how they've been handled.' Rare steaks, tartare, sushi, ceviche or raw seafood, or inadequately prepared meat, fish, or seafood can increase your risk for consuming bacteria, parasites, or viruses, Silberman said. Fresh fruits and vegetables Fresh fruits and vegetables that seem to have been sitting out for a while could attract germs that might make you sick, Rissetto said. Opt for cooked produce when you can, which will ensure that it reaches temperatures high enough to kill pathogens. 'If you're going to eat fresh fruits and vegetables, they are safest when washed with potable water and peeled by the person who eats them,' Baum added. Also, choose fruits and vegetables with thick skins — like bananas, oranges or avocados — that can be peeled, Silberman said. 'Peel them yourself to reduce the possibility of eating pathogens.' Dairy Pasteurized milk and dairy products from sealed containers are usually safe to consume, according to the CDC. But unpasteurized items, including cheese, yogurt, or ice cream, are more likely to contain hazardous germs, like listeria, salmonella, or E. coli, Silberman said. It's also a good idea to avoid dairy that's been stored at room temperature or left out, such as cream for coffee. Tap water Alberto Masnovo / Getty Images Contaminated water is a big cause of traveler's diarrhea. 'Since pathogens aren't visible to the naked eye, it's hard to tell if the water is safe to drink,' Baum said. To learn about the safety of tap water in your destination, visit the CDC's travelers' health website, where you can search by country. Whenever you're not sure about the safety of water, drink factory-sealed bottled water and remove ice from your drinks, Baum said. You can also boil water for at least a minute. Be careful not to swallow any water in the shower if you're visiting a place where the water isn't safe to drink, and use bottled water to brush your teeth, Rissetto said. Certain types of street food DigiPub / Getty Images Sampling food from street vendors is a fun way to sample local cuisine, but the CDC warns that some may not adhere to the same safety practices — like hand-washing and checking food temperatures — as restaurants. It's always best to avoid foods and drinks that seem to be sitting around for a while. Items that come straight off a grill, for instance, that are piping hot and cooked are likely safer. What If You Get Sick While Traveling? If, despite your best efforts, you do get a case of traveler's diarrhea, it's usually not serious. But it can persist for a few days or a week (longer if it's caused by a parasite), ruining your trip. Silberman offered these tips for taking care of yourself if that happens: Stay hydrated. Diarrhea and vomiting can be dehydrating, so drink lots of bottled water or other safe fluids. Take an over-the-counter medication. Antidiarrheals, like loperamide (Imodium), or anti-nausea drugs, like dimenhydrinate (Dramamine), help relieve symptoms. Talk to a healthcare expert first, though, especially if you're taking other medications. See a doctor. If your symptoms aren't going away, they're severe, or you also have a fever, bloody stool, or dehydration, seek medical attention. Call your doctor when you get home if you still have symptoms or if you have an underlying medical condition. No one wants to get sick while traveling, of course. But remember that foodborne illness can happen anywhere, Rissetto noted. 'If we go on vacation overly worried about every single thing we're eating, we might not be able to truly enjoy the experience,' she said. 'You can determine what's right for you in the moment.'

Dementia Risk Declining With Each Generation, Says Promising New Study
Dementia cases are on the rise around the world. In 2021, 57 million people were living with one of the neurodegenerative diseases under the dementia umbrella, and by 2050, that number is expected to reach 153 million. But a new study suggests the tides may be turning, with younger generations facing lower risks for the disease as they age. The research team, led by economist Xiaoxue Dou from the University of Queensland in Australia, ran a cross-sectional observational study using health survey data from the US, Europe and England: one that's representative of cross-sections of the populations involved at a single point in time, and based on observational data. The researchers only used variables that were available across all the survey data to estimate participants' dementia status, to compensate for any missing observations. "Birth cohorts born more recently were less likely to develop dementia in all three regions, albeit at different rates," the authors state in a journal article. "This decreasing trend was more pronounced among women than men." They particularly focused on people aged 71 years or older, with the data sorted into age groups spanning four years. Compared with the older groups, younger cohorts had lower age-specific dementia prevalence rates: 21.2 percent for those in the US study; 38.9 percent in the European study; and 28.3 percent in England. "For example, in the US, among people aged 81 to 85, 25.1 percent of those born between 1890-1913 had dementia, compared to 15.5 percent of those born between 1939-1943," economist and co-author Sabrina Lenzen of the University of Queensland told Nicola Davis at The Guardian. The team cautions their data may not accurately reflect what is happening in minority groups. But the findings suggest that, while aging populations globally will probably mean greater numbers of people living with dementia, the percentage of people affected may actually be decreasing, at least among the groups studied. This generational decrease in dementia risk, the study's authors write, "has important implications for health care planning, long-term care policies, and workforce requirements in aging populations."
