Body Mass Index

For people giving birth to twins, the gestational weight gain range with the lowest risk for adverse perinatal outcomes was similar among those with a pre-pregnancy BMI of underweight or normal weight.

The Women’s Preventive Services Initiative — or WPSI — issued new guidelines for preventing weight gain in women aged 40 to 60 years.

Children conceived through assisted reproductive technology — or ART — were “shorter, lighter and thinner” compared with naturally conceived children at birth through early adolescence, data published in JAMA Network Open showed.

Obesity is a dysregulation of the energy balance pathways in the human body. People with obesity are defending an abnormal body weight set point, and we can recognize and start to address that with the easiest tool we have, BMI. You just need height and weight, and you can calculate it. However, in certain populations, the standard cutoff values do not accurately correspond to risks. Someone who is Asian and has a BMI of 23 kg/m2 or 24 kg/m2, may have a “normal” BMI, but in reality, patients of Asian descent have a higher risk at a lower BMI. It’s the same thing for African Americans at higher BMI cutoff values.

Obesity prevalence is on the rise across the U.S., but some groups are at a greater risk for the disease than others.

In patients with CHD, circuit resistance training is effective in improving BMI and body fat percentage and may help delay disease progression, according to data from a meta-analysis of exercise studies.

COVID-19 vaccines are effective in reducing the risk for hospitalization and death in all BMI Groups, though the odds for adverse outcomes were higher for vaccinated people with very high or very low BMI compared with normal weight.

Increases in BMI and abdominal obesity appeared associated with higher risk for male breast cancer, according to study results published in Cancer Epidemiology.

Lower BMI at the time of surgery was associated with increased functional improvements for patients undergoing total joint arthroplasty, thus patients should focus on optimizing preoperative BMI, according to published results.

Published results found no association between BMI and functional outcomes, survivorship, or all-cause and aseptic revisions in patients undergoing modern cementless total knee arthroplasty.
