A study found that exposure to traffic-related air pollution in childhood is associated with increased body mass index (BMI) and insulin resistance later in life. Higher BMI growth from early adolescence into young adulthood may partially explain this link.
A new study identifies that the internationally recognized body mass index (BMI) cut-off points overestimate overweight and obesity in male athletes. The researchers propose new cut-off points of 28.2 kg/m² for overweight and 33.7 kg/m² for obesity, taking into account lower body fat percentages typical of athletes.
Among US adults aged 20-59, obesity prevalence by BMI was nearly identical to the confirmed excess adiposity rate. Approximately 98% of obese individuals had excess adiposity, suggesting a strong correlation between the two measures.
Research found a significant increase in the prevalence of overweight and obesity among English adolescents, from 22% to 33% between 2008-2010 and 2021-2023. Adolescents living with these conditions are at higher risk for developing comorbidities, including mental health issues, physical problems, and cardiometabolic diseases.
A new study found that tirzepatide can produce sustained weight loss of up to 31% in adults with overweight or obesity without diabetes, regardless of age or BMI. The study also identified patterns of weight loss trajectories and found that females and those without obesity-related complications may be more responsive to the medication.
A new analysis of the SURMOUNT-1 trial found that around two-thirds of participants regained only 5% or less of their lowest weight over three years. The study suggests that most patients receiving tirzepatide had a relatively stable weight journey, with limited weight regain after reaching their nadir weight.
A large majority of older Americans believe health insurance – including Medicare – should cover anti-obesity medications. Nearly 37% of respondents met the criteria for overweight and 36% for obesity. Medicare currently covers a drug used for weight management but only in people with diabetes or a history of heart attack or stroke.
Most older U.S. adults support Medicare covering weight management medications, particularly those with a BMI of 30 or greater. The survey also found that more than half of participants were interested in using these medications to manage their weight.
New research suggests that maintaining a healthy weight throughout life and losing weight later in life may reduce the risk of kidney cancer. Higher BMI at various ages across adulthood was associated with increased risks of developing different types of kidney cancer, including renal cell carcinoma, papillary RCC, and chromophobe RCC.
A study published in The Journal of the National Cancer Institute found that waist circumference is a stronger risk marker than body mass index (BMI) for obesity-related cancers in men. However, this association was not observed in women.
A new study found that new-onset type 2 diabetes is associated with an increased risk of certain obesity-related cancers, such as bowel and pancreatic cancer.

Research suggests that having an overweight or obesity trajectory during childhood is associated with a higher risk of chronic obstructive pulmonary disease (COPD) in adulthood. The study found that women with above-average childhood BMI trajectories had a 26% higher risk, while those with an obesity BMI trajectory had a 65% higher risk.
Research suggests that people with obesity experience a redistribution of their body compartments, such as increased fat trunk accumulation and lower muscle mass, particularly in extremities, as they age. This shift occurs without significant changes in BMI, making it a less useful tool for assessing weight status.
A recent study published in Heart journal found that extreme weight fluctuations significantly increase the risk of death among obese individuals with cardiovascular disease. Both weight loss and gain above 10kg raise mortality risk, highlighting the importance of maintaining a stable weight even within the obese range.
A new study found that waist-to-height ratio is more accurate than BMI in estimating body fat in children. The study included 7,600 children and found that 64% of those classified as BMI-overweight had normal fat according to waist-to-height ratio.
A responsive parenting intervention demonstrated a significant reduction in child weight outcomes from age 3 to 9 compared to a control group. The intervention's benefits were most pronounced among female participants, and its long-term effects may be sustained with a life-course approach.
A new study found that the proportion of visceral fat, rather than the absolute amount, is a stronger predictor of high triglyceride levels and inflammation. Lowering visceral fat proportion during weight loss can lead to better metabolic health outcomes.
A third of children and adolescents will be overweight or obese within the next 25 years, according to a new study. The global obesity rate for those between 5-24 years old tripled from 1990 to 2021, rising by 244 per cent to 174 million.
