Researchers found that people who lost about 6.5% of their body weight -- without using weight loss drugs or surgery -- reaped big health benefits later in life, CNN reported. For someone who weighs 180 pounds, that's just shy of a 12-pound weight loss. "Although correcting midlife overweight without surgical or pharmacological treatment is challenging, our results suggest that it is feasible and may be associated with decreased long-term risk of cardiovascular diseases, other chronic conditions, and mortality outcomes associated with overweight," the study, led by Dr. Timo Strandberg, a professor of geriatric medicine at the University of Helsinki in Finland, concluded. Published Tuesday in JAMA Network Open, it looked at data from nearly 23,000 adults across three time periods, going back to the 1960s. Researchers grouped folks based on their body mass index (BMI) at the start and whether they gained, lost or maintained weight. (BMI is an estimate of body fat based on height and weight.) Then, they checked hospital and death records. People who lost weight were less likely to suffer from heart attacks, strokes, cancer, asthma and lung diseases like COPD, the study found. They were also less likely to die from any cause over the next 35 years. It's worth noting that this weight loss happened before popular weight loss medications and surgeries were available. That means most of the health improvements likely came from diet and exercise changes. "The study is important because it provides evidence of the relationship between weight loss and both cardiovascular disease and mortality, which hasn't been studied enough," Dr. Aayush Visari, a clinical researcher at Rutgers Robert Wood Johnson Medical School in New Jersey, told CNN. But both Visaria and Strandberg noted that BMI, used in the study to track people's weight, is an imperfect measure. BMI doesn't show where fat is stored or how much muscle someone has, which can affect health risks. Other research has shown that belly fat and fat around organs may matter more than overall weight. "There's so many variables that might play into how someone's body composition changes, even though maybe their weight might not change as much," Visaria said. While this study couldn't prove that weight loss alone caused the health benefits, the lifestyle changes that led to it -- like healthier eating and more exercise -- also likely played a big role. Experts recommend aiming for 150 minutes of moderate exercise (like walking or biking) each week, plus two days of muscle-strengthening activities. Eating a Mediterranean-style diet rich in fruits, veggies, nuts and olive oil can also help, CNN reported. Lifestyle is always important when it comes to good health, meaning that you should strive to eat nutritious foods and be active even if you are using weight loss medications, Visaria added. Strandberg said society also needs to make it easier for people to access healthy food and places to be active. More information The Mayo Clinic has more on the benefits of regular physical activity.

Climate change could be fueling cancer deaths in women
Higher temperatures spurred by climate change could be increasing women's risk of cancer, a new study says. Photo by Adobe Stock/HealthDay News Higher temperatures spurred by climate change could be increasing women's risk of cancer, a new study says. Increasing heat in the Middle East and North Africa has made breast, ovarian, uterine and cervical cancers more common and more deadly, researchers reported Monday in the journal Frontiers in Public Health. For each additional degree Celsius, cases and deaths of female cancers increased, researchers found. "As temperatures rise, cancer mortality among women also rises -- particularly for ovarian and breast cancers," lead investigator Wafa Abu El Kheir-Mataria said in a news release. She's a global health governance and health equity researcher at the American University in Cairo. Increased cancer in these countries could serve as a bellwether for what might happen in nations like the United States with currently cooler climes, researchers said. "Although the increases per degree of temperature rise are modest, their cumulative public health impact is substantial," Mataria added. For the study, researchers tracked cancers occurring in 17 Middle Eastern and North African countries, including Algeria, Bahrain, Egypt, Iran, Iraq, Jordan, Kuwait, Lebanon, Libya, Morocco, Oman, Qatar, Saudia Arabia, Syria, Tunisia, United Arab Emirates and the Palestinian territories. These countries are already experiencing striking temperature increases tied to climate change, researchers noted. "Women are physiologically more vulnerable to climate-related health risks, particularly during pregnancy," senior researcher Sungsoo Chun said in a news release. He's associate chair of the Institute of Global Health and Human Ecology at the American University in Cairo. Researchers compared each nation's temperatures to its cancer statistics between 1998 and 2019, and found that rising heat was associated with more cancer cases and deaths. Cancers increased by 173 to 280 cases per 100,000 people for every additional degree Celsius, results show. Ovarian cancers cases rose the most, and breast cancers the least. Likewise, cancer deaths rose by 171 to 332 deaths per 100,000 for each degree of temperature rise, with the greatest increase in ovarian cancer and the smallest in cervical cancer. Six countries experienced the brunt of this increase in cases and deaths -- Qatar, Bahrain, Jordan, Saudi Arabia, the United Arab Emirates and Syria. Although hotter temps are a probable risk factor, the heat might also increase other cancer risk factors like air pollution, researchers said. "Temperature rise likely acts through multiple pathways," Chun said. "It increases exposure to known carcinogens, disrupts healthcare delivery, and may even influence biological processes at the cellular level. Together, these mechanisms could elevate cancer risk over time." However, researchers noted that the study can't draw a direct cause-and-effect link between climate change and cancers. More research is needed to better understand how higher temperatures might influence cancer risk. In the meantime, researchers said public health officials should consider climate-related risks in their planning. "Strengthening cancer screening programs, building climate-resilient health systems, and reducing exposure to environmental carcinogens are key steps," Chun said. "Without addressing these underlying vulnerabilities, the cancer burden linked to climate change will continue to grow."

United States had 1.5 million excess deaths following COVID-19 pandemic
Excess deaths in the United States have continued to mount following the COVID-19 pandemic. Photo by Adobe Stock/HealthDay News Excess deaths in the United States have continued to mount following the COVID-19 pandemic, leading to an early demise for hundreds of thousands, a new study says. More than 1.5 million "missing Americans" died in 2022 and 2023, deaths that would have been averted if U.S. death rates matched those of other wealthy nations, researchers reported Friday in JAMA Health Forum. In fact, nearly 1 of every 2 deaths among people younger than 65 (46%) in 2023 would not have occurred if U.S. death rates mirrored those of peer nations, researchers found. "The U.S. has been in a protracted health crisis for decades, with health outcomes far worse than other high-income countries," lead researcher Jacob Bor, an associate professor of global health and epidemiology at the Boston University School of Public Health, said in a news release. "Imagine the lives saved, the grief and trauma averted, if the U.S. simply performed at the average of our peers," Bor added. "One out of every 2 U.S. deaths under 65 years is likely avoidable. Our failure to address this is a national scandal." For the study, researchers tracked death record data from the United States and 21 other high-income nations from 1980 to 2023, including more than 107 million U.S. deaths and 230 million deaths among the peer nations. The other wealthy nations included Australia, Canada, France, Japan and Britain, researchers said. Overall, the United States had nearly 15 million excess deaths during the four decades in question, when stacking its death rate against that of other wealthy countries, results show. In 1980, the United States actually outperformed other nations, with 42,000 fewer deaths than might be expected compared to the death rates of peer nations. But in 1990, the United States had more than 89,000 excess deaths, leaping to nearly 355,000 in 2000 and 409,000 in 2010, results show. Excess deaths peaked in the United States during the COVID-19 pandemic, with more than 1 million dead in 2020 and nearly 1.1 million in 2021, researchers said. But excess deaths remained high even after scientists conquered COVID, with more than 820,000 in 2022 and 705,000 in 2023, the study says. "The 700,000 excess American deaths in 2023 is exactly what you'd predict based on prior rising trends, even if there had never been a pandemic," said researcher Elizabeth Wrigley-Field, an associate professor of sociology at the University of Minnesota. "These deaths are driven by long-running crises in drug overdose, gun violence, car collisions, and preventable cardiometabolic deaths," she added in a news release. In 2023, needless excess deaths accounted for nearly 23% of all deaths in America, researchers report. These excess deaths show how the policies of other peer nations better protect the health of their citizens, senior researcher Andrew Stokes said in a news release. "Other countries show that investing in universal healthcare, strong safety nets, and evidence-based public health policies leads to longer, healthier lives," said Stokes, an associate professor of global health and epidemiology at the Boston University School of Public Health. "Unfortunately, the U.S. faces unique challenges; public distrust of government and growing political polarization have made it harder to implement policies that have proven successful elsewhere," he added. The executive actions and policies enacted under the second Trump administration threaten to drive excess deaths even higher, Bor said. For example, the U.S. House of Representatives' approved version of legislation containing President Donald Trump's second-term agenda includes potential cuts to Medicare and Medicaid that would make excess deaths even more likely. "Deep cuts to public health, scientific research, safety net programs, environmental regulations, and federal health data could lead to a further widening of health disparities between the US and other wealthy nations, and growing numbers of excess -- and utterly preventable -- deaths to Americans," Bor said.

Reducing Dietary Fat May Ease Symptoms of Depression, Study Finds - Jordan News
A new study suggests that cutting calories or following a low-fat diet may lead to a slight reduction in depression symptoms. Researchers from Bond University in Queensland, Australia, analyzed 25 clinical trials involving over 57,000 participants who either received nutritional guidance as part of their treatment plans or continued with their regular eating habits. اضافة اعلان Key Findings: Calorie restriction and low-fat diets were associated with modest improvements in depression, especially in adults at risk of cardiovascular disease—such as those with obesity, high blood pressure, high cholesterol, elevated blood sugar, smoking habits, or low physical activity. The impact on anxiety was less clear. The Mediterranean diet showed uncertain effects on depression, anxiety, and overall quality of life. Despite the small effect size, the researchers believe that long-term dietary changes might still offer notable mental health benefits over time. Important Note: The team recommends that individuals consult healthcare professionals before making any major dietary adjustments, especially if they have underlying health conditions or are undergoing treatment for mental health issues.
