Recent study reveals directional selection on height, age at first birth, and body mass index in males, while stabilizing selection is detected for several traits in older adults. The findings shed light on the ongoing forces shaping human evolution.
Researchers at McMaster University have identified nine genes that contribute to weight gain in individuals with a high body mass index. These genes can amplify weight gain by up to four times, making them a significant factor in the development of extreme forms of obesity.
Research found that using technology before bed is associated with less sleep, poorer sleep quality, and higher body mass indexes (BMIs) in children. Children who used devices before bed averaged an hour less of sleep than those who did not.
A new study analyzed data from 60,000 parents and children to establish the relationship between body mass index (BMI) and mortality risk. The research found that previous studies had underestimated the harmful effects of being overweight, with high BMI linked to increased mortality risk.
A global longitudinal study confirmed that people with high body mass index (BMI) are more likely to develop dementia than those with normal weight. The study analyzed data from over 1.3 million adults in the US and Europe, finding that individuals near dementia onset tend to have lower body weight.
A study published in The Lancet Diabetes & Endocrinology found that diabetes and high BMI were responsible for 544,300 new cancer cases globally in 2012. The authors project a significant increase in the proportion of cancers attributable to these risk factors, particularly in low- and middle-income countries.
A new study found that fat distribution patterns, not just overall weight, are linked to heart attack risk in women and men. Women had higher subcutaneous fat but lower lean mass compared to men, who had more visceral adipose tissue and ectopic fat.
A new study suggests that overweight women with higher body mass index (BMI) may need shorter intervals between mammography screening exams. Women with higher BMI face an increased risk of not detecting their breast tumor until it has become large, leading to a worse prognosis.
A large study found that unhealthy weight before pregnancy is associated with a small increased risk of severe maternal illness or death. Women with underweight, overweight, and obese body mass indexes before pregnancy had higher absolute risks of severe complications.
A recent NIH study found that obese pregnant women are more likely to give birth to large infants, with fetuses experiencing longer bones and higher birth weights. This increased fetal growth may predispose these infants to obesity and cardiovascular disease later in life.
Researchers found that a positive outlook and BMI both contribute to good health among college students. The study showed subjective happiness had the most significant impact on overall health, followed by hope and then BMI. In contrast, gratitude and life satisfaction didn't influence overall health individually.
Research finds that obesity is associated with a higher degree of synovitis in RA patients, leading to worse clinical responses to treatment. Patients who are overweight or obese tend to have higher histological scores and more inflammation in their joints.
A study of Chilean adults aged 65 and older found that maintaining ideal cardiovascular health behaviors, such as regular physical activity, a healthy diet, and not smoking, can reduce the risk of disability. The researchers also discovered that having an ideal body mass index (BMI) can lower disability risk, particularly for those wit...
A high waist-to-hip ratio is associated with a significantly higher rate of complications, longer hospital stays, mortality, and 30-day readmissions after emergency general surgery procedures. The study suggests that measuring waist-to-hip ratio via CT scan may be a reliable predictor of adverse outcomes.
A recent study published in Human Reproduction found that underweight women are at a greater risk of experiencing an early menopause compared to lean or normal weight women. Women who were underweight as teenagers or in their mid-30s had a significant increase in the risk of early menopause, with some women reporting a 50% higher risk.
A new study from UMass Amherst suggests that women who are underweight during adolescence or adulthood may be at increased risk for early menopause. The research, which followed nearly 80,000 women over 25 years, found a significant association between being underweight and an earlier onset of natural menopause.
Researchers found that genetic predisposition increases risk of high triglycerides, but maintaining a healthy body weight or changing diet can help reverse the risk. A specific gene mutation was associated with higher circulating triglycerides, but the correlation was dependent on BMI and dietary intake.
Researchers found that patients with acute kidney injury had higher VTE rates despite prophylaxis, highlighting the need for optimal heparin dosing in these cases. The study also showed that creatinine clearance was not associated with VTE rates when unfractionated or low-molecular-weight heparins were given.
A study presented at the ANESTHESIOLOGY 2017 annual meeting found that women giving birth in winter or spring are less likely to develop postpartum depression. Higher gestational age and not having anesthesia during delivery increased risk, while increased body mass index was associated with a higher risk.

A new study by Imperial College London and the World Health Organization found that childhood and adolescent obesity rates increased tenfold over four decades, from less than 1% in 1975 to nearly 6% in girls and 8% in boys in 2016. The number of obese children and adolescents is expected to surpass those who are underweight by 2022. He...
The global prevalence of child and adolescent obesity has increased significantly over the past four decades, from 0.7% to 5.6% for girls and 0.9% to 7.8% for boys. Despite this rise, more children remain moderately or severely underweight than obese globally, highlighting the need to improve food security.
A new study suggests that weight loss in adults leads to significant cost savings, peaking at age 50. The research found that an adult who goes from obese to overweight can save $17,655 in direct medical costs and productivity losses over their lifetime, while losing weight from obese to healthy results in a savings of $28,020.
A 45-year-old woman developed a rare but life-threatening condition called fat embolism syndrome (FES) after undergoing liposuction. FES is notoriously difficult to diagnose due to a lack of standardized diagnostic criteria, emphasizing the need for clinicians to think outside the box and consider alternative diagnoses.
A Chinese study found that women with visceral fat (around internal organs) are at higher risk for developing ER- breast cancer, while those with subcutaneous fat are more likely to develop ER+ breast cancer. The study's findings suggest a complex link between breast cancer and obesity.
Chinese children who go to bed later and sleep less are more likely to be overweight, with each hour later bedtime increasing BMI scores. The study suggests cultural factors, such as emphasis on studying and academic achievement, contribute to shorter sleep durations.
A nationwide study found that women with PCOS have a four times greater risk of developing type 2 diabetes and are diagnosed at an average age of 31, compared to those without PCOS.
Underweight patients undergoing cardiac catheterisation are more likely to die, experience longer hospital stays, and incur higher costs compared to normal weight or obese patients. Morbidly obese patients, on the other hand, have better outcomes despite having a lower BMI.
A study found associations between parental BMIs and offspring metabolic traits, but the link was not significantly stronger for maternal BMI, arguing against an intra-uterine mechanism. After accounting for offspring BMI, the data suggested that familial factors rather than intra-uterine overnutrition explain the relationship.
A new study at Drexel University found that female college students who weighed themselves daily lost body fat and experienced modest BMI changes, while those who did not saw little change. The researchers suggest that daily self-weighing can motivate healthy eating and exercise behaviors.
New Indiana University research suggests that limiting access to fast-food restaurants will not reduce obesity. Instead, the study found that changes in the availability of healthy food options, such as supermarkets and nutritious food outlets, may make it easier for people to access healthy foods.
A Norwegian study found that increasing Body Mass Index above one unit from first to second pregnancy drastically increases the risk of developing gestational diabetes mellitus (GDM). Women with BMI less than 25 in first pregnancy showed a strongest risk associated with weight gain, while overweight women who reduced their BMI by more ...
Research finds that black women who gain fat around their midsection are more likely to accumulate heart fat, while white women's risk increases when they gain weight overall. The study, which analyzed data from over 500 women, suggests that excess abdominal fat is a greater threat for both black men and women.
A new study published in PLOS Medicine found that women who gained more than one BMI unit between pregnancies had a doubled risk of developing gestational diabetes. The increased risks were strongest in women with a low BMI, and evidence suggested that reducing weight between pregnancies can help prevent GDM.
Patients who undergo bariatric surgery are more likely to achieve a BMI of less than 30 if they have a preoperative BMI of less than 40. However, delaying surgery until higher weights can result in inferior outcomes.
A large new study shows that only one in three patients who have bariatric surgery succeed in getting their body-mass index below 30 in the first year. Patients with lower BMIs before surgery had higher odds of achieving this goal and better health outcomes, including stopping medication for high blood pressure and cholesterol.
Loma Linda University researchers found four factors associated with decreased body mass index: single or dual meals, overnight fasting up to 18 hours, breakfast instead of skipping it, and making breakfast the largest meal of the day. Making breakfast the largest meal resulted in a more significant decrease in BMI compared to lunch.
A study published by The BMJ finds that healthy eating and physical activity during pregnancy limits weight gain and lowers the odds of having a caesarean section. The benefits are consistent regardless of age, ethnicity, BMI, or underlying medical conditions.
A new study found that children born prematurely to mothers who were overweight or obese before pregnancy are at higher risk for low cognitive scores and difficulties with self-regulation. The study suggests that behavioral interventions to reduce pre-pregnancy weight may help mitigate these impairments.
A large-scale study found that higher body mass index (BMI) is associated with an increased risk of coronary heart disease, hypertension, and type 2 diabetes. The study, which included over 119,000 participants, also showed that higher BMI was linked to higher systolic and diastolic blood pressure.
Researchers propose guidelines for semi-autonomous systems, including veto control and data protection. The possibility of 'brainjacking' also raises concerns about security solutions.

Researchers analyzed data from over 2 million adolescents, showing a significant association between adolescent obesity and mid-life cardiovascular mortality.
A Swedish study published in Neurology found that teenage weight gain is associated with a higher risk of stroke in adulthood. The study followed 37,669 men and found that those who experienced a significant increase in BMI from childhood to age 20 were more likely to develop high blood pressure and stroke.
A National Institutes of Health-funded study found that moderate-intensity exercise reduced the risk of major mobility disability by 31% in older adults with extreme obesity. The structured physical activity program improved participants' ability to perform common daily activities, such as walking a block around the neighborhood.
A new study from the University of Bath's School of Management shows that marriage is associated with weight gain in men, adding approximately three pounds to their BMI. The early days of fatherhood also contribute to this effect, while a decrease in male BMI is observed during the period just before and after divorce.
The USPSTF recommends screening for obesity in children and adolescents 6 years old and older, offering comprehensive behavioral interventions to promote weight improvements. This recommendation is based on moderate certainty, as screening can lead to small harms but also improve weight status with moderate net benefits.
A University of Alberta research team found that patients with obesity have a higher risk of infection within 30 days after heart bypass surgery, and 88% of these patients received non-surgical PCI. This increased risk may be due to the fact that patients with obesity are more likely to receive PCI.
A population study found that being overweight or obese, as defined by body mass index, abdominal obesity, and higher body fat percentage, is associated with a higher risk of developing rheumatoid arthritis in women. In contrast, no clear association was found between RA risk and BMI criteria for men.
A recent study published in PLOS Medicine suggests that genetic variants associated with higher body mass index (BMI) are linked to lower risk of Parkinson disease. The researchers used a Mendelian randomization approach to examine the relationship between BMI and Parkinson disease, and found an 18% lower risk of Parkinson disease amon...
A new study reveals that 30% of the world's population is affected by weight problems, resulting in over 4 million deaths attributed to excess body weight. The study found that nearly 40% of these deaths occurred among people with a BMI below the threshold for obesity, highlighting the risks associated with being overweight or obese.
A new study from The Ohio State University Wexner Medical Center reveals that female runners with a body mass index (BMI) of less than 19 are more likely to develop stress fractures. Lighter women who suffered stress fractures took longer to recover, highlighting the importance of maintaining a healthy BMI through resistance training.
A recent Danish study found that maternal daily consumption of artificially-sweetened beverages during pregnancy was associated with a higher body mass index score and increased risk of overweight/obesity at 7 years. This study suggests that substituting SSBs with artifically sweetened beverages may increase offspring obesity risk.
A study found that obese patients undergoing shoulder joint replacement surgery are at increased risk of complications, including the need for revision surgery and postoperative infections. The risk of revision surgery increases steadily with increasing body mass index (BMI) in obese patients.
A systematic review and meta-analysis found that women who gained more than the recommended weight during pregnancy were at a higher risk of small for gestational age, preterm birth, and cesarean delivery. In contrast, those who gained less than the recommended weight had a lower risk of large for gestational age and macrosomia.
A new study found that two interventions, one providing enhanced primary care and the other coaching, improved BMI and parents' sense of empowerment. Both programs also increased parents' confidence in addressing their child's weight problem.
Researchers found that higher body mass index (BMI) can cause worse cardiovascular health in young adults as young as 17, according to a study using data from the Avon Longitudinal Study of Parents and Children. The study suggests that tackling obesity from an early age may help prevent cardiovascular changes that are precursors to car...
Research published in the British Journal of Cancer found that carrying excess body fat can increase cancer risk, with waistline and hip measurements being key indicators. The study combined data from over 43,000 participants and found that adding just 11cm to the waistline increased obesity-related cancer risk by 13%.
A new study found that smokers without chronic obstructive pulmonary disease (COPD) who experience vascular pruning, or the reduction of distal pulmonary blood vessels, are at a higher risk of death. Vascular pruning was not associated with an increased risk of death in smokers with COPD.
Researchers at Vrije Universiteit Amsterdam identified 52 genes associated with intelligence, including 40 previously unknown discoveries. The study reveals a correlation between genetic influences on intelligence and educational attainment, as well as traits like autism spectrum disorder and schizophrenia.
Achieving moderate-to-vigorous physical activity guidelines, reducing TV viewing time, and ensuring adequate sleep duration are associated with lower BMI and body fat in children. Meeting these guidelines can reduce the risk of obesity and related health problems.
