Researchers found that only one formula was accurate more than 49% of the time, highlighting a need for caution when using these metrics.
Fibromyalgia symptoms worsen with age, according to a Mayo Clinic study. Young and middle-aged patients experience more severe physical health problems and lower quality of life compared to their older counterparts.
A new study found that middle-aged men are at a greater risk for having a first heart attack due to high cholesterol levels, unlike women who are also at risk but to a lesser extent. The study suggests that men with high cholesterol should be treated more aggressively to prevent infarctions and save lives.
Smokeless tobacco prevalence among US youths remained stable from 2000 to 2011, with declines observed in younger age groups. The prevalence increased in the 15-17 year age group. Evidence-based interventions are needed to reduce smokeless tobacco use.

Research at Queen's University Belfast found that children who grew up during the worst years of violence have the highest suicide rates and most rapidly increasing rates. The study attributes this to a range of factors including social isolation, poor mental health, and increased political stability.
Preventive mammography rates in women aged 40-49 have dropped nearly 6 percent nationwide since the USPSTF recommended against routine mammograms. The decline is consistent with public resistance to the guidelines change and a modest effect seen in the first year after publication.
A proactive solution could help prevent injuries by restricting driving privileges under favourable conditions. Exemptions would be granted for certified healthy seniors, shifting the onus from others to seek exemptions.

A new analysis of census data estimates that 750,000 soldiers died in the American Civil War, a 20% increase from the commonly cited figure of 620,000. This reevaluation is based on a more detailed comparison of male and female survival rates using historical census data.
Researchers at the University of North Carolina discovered that the pelvis continues to widen as people age from 20-79, leading to an estimated three-inch increase in waist size. This finding suggests that pelvic growth contributes to increased body weight and body fat accumulation over time.
Two new studies show a significant drop in mammograms performed in women aged 40-49, leading to decreased benefits of early detection. Researchers found that cancers detected earlier through screening mammography presented at an earlier stage than those not screened, resulting in lower survival rates if guidelines are followed.
A study published in Blood reveals that imatinib treatment has no significant impact on the outcome of chronic myeloid leukemia (CML) patients aged 65 and older. The research found that complete hematologic response rates, cytogenetic response rates, and overall survival rates were similar between younger and older patients treated wit...

Women with severe angina are three times more likely to develop severe coronary artery disease than men. The study found that even younger women face a higher risk of developing CAD than men in the same age group. Diabetes and high blood pressure also play a significant role in increasing the risk, particularly among young women.

A study analyzing 8,970 ICSI cycles found that younger women (35 and under) achieved a pregnancy in 50.8% of their first attempts, decreasing to 18.2% by the fifth attempt. In contrast, women over 40 had a lower pregnancy rate of about 20%, consistent throughout four attempts.
Researchers at Columbia University's Mailman School of Public Health discovered that the prevalence of pre-cancerous masses in the colon is similar between patients aged 40-49 and 50-59. The study suggests that starting colon cancer screening at age 40 may help decrease its prevalence and save more people from the disease.
A new study found that the prevalence of pre-cancerous masses in the colon is similar between average-risk patients aged 40-49 and 50-59. This suggests that colon cancer screening may be feasible at an earlier age, potentially reducing incidence and saving lives.
The proposed global goal aims to reduce chronic disease mortality by 2% yearly, averting millions of deaths and saving billions of dollars. In 23 studied countries, this reduction could extend life expectancy by up to 18 years.

The hedonic treadmill hypothesis suggests that continued income growth can lead to an ongoing consumption race where individuals consume more to maintain a constant level of happiness.
High rates of uninsured Hispanics and unstable coverage put them at risk for preventable health problems. One quarter of Hispanics aged 50-64 went without needed care due to costs.
Male injecting-drug users are at greater risk of drug-related death than females. Older users (over 34 years) are two to six times more likely to die than younger users.
The study estimates that the national prevalence of Alzheimer's disease will increase significantly by 2050, with 60% of cases projected to affect people 85 and older. This is due to declining death rates after age 65, allowing more people to survive to older ages where the risk of AD is highest.
Younger women with Hodgkin's Disease are at a higher risk of developing breast cancer after radiotherapy, particularly if they have a family history or underwent splenectomy. Modern treatment methods aim to lower this increased risk.
