A study by Michigan State University found that BMI does not accurately reflect body fat percentage in most cases, particularly among athletes and younger individuals. Researchers suggest reevaluating BMI cutoff points for different age groups and fitness levels to improve its accuracy as a fat indicator.
A new study published in Pediatrics found that higher body mass index scores in girls as young as age 3 and large increases in BMI between ages 3 and first grade are associated with earlier puberty. The study suggests that childhood obesity may contribute to an earlier onset of puberty in girls.
A nationwide study found that obese children benefited from attending school, with their rate of BMI gain reduced the most. Schools seem to help limit the spread of obesity due to their structured environment, restricting access to food and promoting healthier choices.
Scientists identified a variant of apolipoprotein C1 protein associated with higher body mass index, obesity, and Type 2 diabetes in American Indians and Mexicans. This discovery can help identify risk factors for diabetes and inform diet and lifestyle choices.
A study by Columbia University's Mailman School of Public Health found that living in densely populated, pedestrian-friendly areas is associated with lower body mass index levels. Researchers discovered that access to public transit, proximity to commercial goods and services, and population density are inversely related to BMI levels.
Researchers found graded associations between psychosocial factors and inflammatory markers, with cynical distrust strongly linked to increased inflammation. The study suggests that behaviors such as smoking may mediate the link between psychosocial factors and cardiovascular disease risk.
A new study has found that excess weight and adult weight gain increase the risk of death from prostate cancer. Higher BMI and weight gain since age 18 were associated with a significantly higher risk of fatal outcomes.
A study of over 100,000 acute heart failure patient episodes found that obese patients had a substantially lower in-hospital mortality rate compared to lean patients. The findings suggest that nutritional/metabolic support may have therapeutic benefit in specific patients hospitalized with heart failure.
A study of 8,404 children found that those with obesity used more healthcare resources and had higher charges than their healthy-weight counterparts. The average adjusted difference in charges was $172 for children with diagnosed obesity.
Women with higher physical activity levels have a lower risk of developing breast cancer, especially for estrogen receptor-positive/progesterone receptor-negative tumors. Physical activity reduces body fat, leading to lower estrogen levels and potentially decreasing ER+/PR+ tumors.
Research suggests that higher body mass index (BMI) in early adulthood is associated with a reduced risk of breast cancer before menopause. This protective effect is not linked to ovulation problems, and the association persists even when adjusting for other factors such as family history and lifestyle habits.
Researchers found that Minnesotans in the Twin Cities metro area are expending a significantly greater amount of energy participating in moderately intense physical activities than they were five years ago. The majority of this energy expenditure came from leisure-time physical activities such as walking, running, or biking.
A 3-year study shows significant improvements in self-esteem, nutrition, physical activity, and low-density lipoprotein (LDL) levels among teen girls participating in the Teen Esteem program. The program aims to address obesity and other health issues in high-risk teen girls.
A study published in Pediatrics reveals a significant increase in children's abdominal obesity, with boys experiencing a 65% rise and girls a 70% increase between 1988 and 2004. This growing trend poses serious health risks, including cardiovascular disease and metabolic syndrome.
Research shows that regular exercise can help obese children shrink their waistlines and reduce their risk of developing cardiovascular disease. After six months, exercising regularly resulted in improved artery flexibility, reduced BMI, and lower cholesterol levels.
A study estimated 25% of Pakistan's population is overweight or obese, with 10% classified as obese. Lower BMI cutoff values may be needed to accurately identify conditions and healthy targets due to associated risks of hypertension and diabetes.
A study of 3,130 adults found that patients with more severe sleep apnea, a high body mass index, or other medical conditions were at a higher risk for serious complications after surgery. Concurrent retrolingual procedures also increased the risk of complications.
A study of 2,223 healthy men and women found that those with high body mass index (BMI) scores performed worse on cognitive tests than those with low BMI scores. The study suggests a possible link between obesity and cognitive decline in middle-aged adults.
A new study found that obese men have lower levels of prostate-specific antigen (PSA) and free PSA, suggesting they may be at higher risk for prostate cancer. The researchers also discovered an inverse relationship between BMI and PSA levels, which was strongest in men under 60.
A new study found that postmenopausal women who exercise regularly and maintain a healthy weight have lower levels of circulating estrogens, which can fuel breast cancer growth. The research suggests that combining weight control with high physical activity is necessary for keeping estrogen levels at a healthy range.
A new study published in Pediatrics found that consuming 100 percent fruit juices is not associated with overweight status among preschool children. The analysis of the largest government database on food consumption suggests that preschoolers are consuming appropriate amounts of juice, averaging 4.7 ounces per day.
A study published in Critical Care reveals that diabetes triples the risk of developing critical illness and dying young compared to non-diabetic individuals. Obesity without diabetes does not significantly increase the risk of critical illness or mortality.
A study published in Annals of Surgery found that duodenal switch surgery produced greater weight loss than gastric bypass in super-obese patients, resulting in higher success rates at one and three years post-surgery. The procedure also had fewer complications and improved nutritional outcomes.
Children who were overweight as toddlers are 5 times more likely to be overweight at age 12. BMI measurements collected over an extended period show a strong correlation between childhood and adolescent obesity. The study suggests that early intervention is crucial in preventing the progression of abnormal weight gain.
A recent study published in Pediatrics has found that children who are overweight at any stage of their growth before age 12 are more likely to be overweight by the time they are 12. The study examined over 1,000 children and discovered that preschool-age children who were medically determined to be overweight at one of three points of...
