A recent study published in the International Journal of Food Sciences and Nutrition found no evidence that soft drinks alone contribute to children's weight gain. Instead, researchers discovered that overweight children consumed more food overall and had a greater tendency towards savory rather than sweet foods.
A recent heart attack increases the risk of developing new-onset diabetes and pre-diabetes by up to four-and-a-half times. Lifestyle factors such as smoking cessation, weight loss, and adherence to a Mediterranean diet can substantially lower this risk.
Researchers at UT Southwestern Medical Center found that waist-to-hip ratio is a stronger indicator of cardiovascular risk than body mass index. The study suggests that measuring this ratio can help identify individuals with an increased risk of heart disease and guide more effective treatment strategies.
A new study shows that a moderate bulge at the waist significantly increases the risk of unhealthy plaque build-up in the arteries. Researchers found that adding several inches to the waist measurement markedly increases the risk, even if body weight remains within a normal range.
A family-based weight management program improved outcomes for overweight children compared to traditional weight counseling, reducing body fat and increasing insulin sensitivity. The study found significant differences in BMI, body weight, and cholesterol levels between the two groups after 12 months.
A Yale-developed weight management program cut diabetes risk and improved BMI in overweight children by increasing insulin sensitivity and reducing body fat. The Bright Bodies program, which combined nutrition education, behavior modification, and exercise, was more effective than traditional clinic-based counseling.
A study of over 42,000 individuals aged 65 and older in Hong Kong found that obese or overweight participants had a significantly lower risk of developing active tuberculosis compared to those at a normal weight. The researchers suggest that obesity may be associated with a lower risk of pulmonary tuberculosis in the elderly population.
Researchers found a link between obesity and left ventricular hypertrophy (LVH), a thickening of the heart muscle, in obese patients with a BMI of 30 or greater. The study analyzed 17,261 heart ultrasounds and identified narrowing of the aortic valve as a strong predictor of LVH.
A new protocol developed by Swedish researchers can identify preschool children at risk for obesity with high precision, using only weight and height data. The protocol has the potential to save significant societal costs and reduce suffering among affected individuals and their families.
Research published in the European Heart Journal reveals obese and very obese patients have a lower risk of dying after treated for heart attacks compared to normal-weight patients. After three years of follow-up, obese patients had less than half the long-term mortality rate as normal BMI patients.
A study comparing patients aged 60 and younger found similar postoperative complication rates, with no age-related mortality differences. Bariatric surgery is also deemed acceptable for Medicare recipients, with expert management leading to low morbidity and mortality rates.
Middle-aged African-American women are more likely to experience obstructive sleep apnea (OSA) symptoms than their Caucasian counterparts, according to a study. Menopausal status was not a significant predictor of OSA symptoms, but race remained a significant factor after adjusting for BMI and menopausal status.
Researchers found that older adults with a history of excess weight in midlife or earlier had worse physical performance than those who were normal weight throughout adulthood. Maintaining healthy weight may prevent or delay physical disability as we age.
A study by Johns Hopkins Bloomberg School of Public Health found that workers with a high body mass index (BMI) are at increased risk of workplace injury. The research suggests that obesity prevention policies and programs in the workplace can also lead to improved injury rates and reduced lost work time.
The Shape Up Somerville program, a community-based environmental change intervention, reduced weight gain among elementary school-aged children by approximately one pound over eight months. The multi-faceted program included initiatives to promote healthy eating options and physical activity in schools, homes, and communities.
The study found significant improvements in insulin resistance, with a 60% reduction in HOMA scores after six months. Additionally, the group experienced substantial reductions in body weight, BMI, waist circumference, and total visceral adipose tissue.

The study recommends choosing lowfat and fat-free milk over sweetened beverages for improved diet quality.
A recent study published in Preventive Medicine found that frequent self-weighing is not associated with depression in women. The research suggests that daily weight monitoring can lead to lower BMI levels and less weight gain, making it a potentially beneficial practice for adults.
Workers with obesity filed twice the number of workers' compensation claims, had seven times higher medical costs, and lost 13 times more days of work compared to non-obese workers. Obesity was also linked to higher risk jobs and more severe injuries.
Studies show obese workers are more likely to file workers' compensation claims for injuries on the job. Older Americans with a BMI of 25-30 have a higher risk of disability but lower risk of death compared to those within the recommended weight range.
A RAND study found that girls living near locked schools tended to be heavier and neighborhoods with locked schools were disproportionately poor and had larger minority populations. Public schools had more active amenities, including baseball fields and paved playing surfaces.
A 20-year study reveals a significant rise in childhood obesity, especially among girls, with four-year-olds being six times more likely to have a BMI over 30 than their counterparts 20 years ago. Young girls are also more likely to be overweight or obese than boys, with nearly a third of ten-year-old girls having a BMI over 25.
