A study supported by the National Institutes of Health found that younger women are nearly twice as likely to be rehospitalized after a heart attack as men. The disparity is largely due to higher rates of risk factors such as obesity and depression among women, which contribute to more adverse outcomes.
New research published in the journal SURGERY found that obesity is associated with increased risk of complications following surgery, including infection, blood clots, and kidney complications. Patients with overweight or obesity had higher risk-adjusted odds of developing these post-operative outcomes compared to those of normal weight.

A comprehensive review of 169 clinical trials found that the effect of fructose-containing sugars on adiposity varies among food sources and energy control. High doses of certain sources, like SSBs, lead to increased body weight, while others, such as fruit and honey, show moderate beneficial effects when consumed in moderation.
A study published in Scientific Reports found that rats exposed to high-fat diets during pregnancy and early life developed a preference for salty taste. This preference was linked to increased levels of AT1 protein in the taste buds, which can lead to higher sodium intake and potentially contribute to obesity and diet-linked diseases.
Researchers found deaths from gallstone disease increased in younger populations and those with Medicaid after Medicaid expansion, highlighting the need for proactive prevention over reactive emergency care. A new healthcare model emphasizing primary care and prevention is proposed to address these inequities.
Researchers found that maternal overweight compromises the placenta's antiviral response, weakening its ability to protect the fetus. The study suggests that adequate antenatal care is crucial in preventing complications from Zika infection.
