In white adults, overweight and obesity (and possibly underweight) are associated with increased all-cause mortality. All-cause mortality is generally lowest with a BMI of 20.0 to 24.9.
How is BMI mortality related?
BMI had J-shaped associations with overall mortality and most specific causes of death; for mental and behavioural, neurological, and external causes, lower BMI was associated with increased mortality risk.
What BMI level is dangerous?
The study finds that obese people — those with a BMI of 30 to 34.9 — have a 44 percent higher risk of death from any cause compared with those in the most-favorable range. Severely obese people (BMI over 35) have an 88 percent higher death risk. And the most obese (BMI over 40) have a 250 percent higher risk.
What is the best BMI for longevity?
Your BMI. Your BMI is [bmi_result] which is in the [bmi_category] category. BMI is a standard way of measuring if people are a healthy weight for their height. For most adults 18.5 to 24.9 is the healthy range.
Which BMI range has the lowest relative risk of death?
A BMI of 24.0 to 28.0 (mean 26.0) among men was associated with the lowest risk of death. Although all-cause mortality was not lowest in the group with a BMI of 24.0 to 28.0 in women, the risk of death was higher than the group with a BMI of 18.5 to 24.0 or ≥28.
How does obesity reduce life expectancy?
Obesity is associated with a reduced life expectancy, largely because obese individuals are at increased risk of so many medical complications. But not all obese individuals are the same, and some do not have the metabolic abnormalities that often accompany obesity.
Does obesity increase mortality?
Overall, obesity is estimated to increase the cardiovascular mortality rate 4-fold and the cancer-related mortality rate 2-fold. As a group, people who are severely obese have a 6- to 12-fold increase in the all-cause mortality rate.
At what BMI do anorexics get hospitalized?
Admission criteria require that patients be less than 70 percent of their ideal body weight, or have a body mass index (BMI) below 15.
Is a BMI of 16 dangerous?
Your body mass index, or BMI, is the relationship between your weight and your height. A BMI of 20-25 is ideal; 25-30 is overweight and over 30 is obese. If your BMI is under 18.5, you’re considered underweight. If your BMI is 18.5-20, you’re a bit underweight and can’t afford to lose more.
What is a good BMI score?

Does your BMI change with age?
For adults ages 20 years and older, BMI incorporates weight and height, but it does not take age or sex into account. A woman tends to have more body fat than a man with the same BMI. Likewise, an older person tends to have more body fat than a younger person with an equal BMI.
What is ideal BMI for female?

Why isn’t the body mass index BMI a perfectly reliable way to estimate your health?
“Because it’s simple,” Ahima said, adding that it’s easy to weigh people and measure their height. For most people, BMI provides a “reasonable measure” of body fat, but is not accurate for athletes (who weigh more because of muscle) or older people who have lost height, he said.
Which condition is associated with obesity?
Obesity is serious because it is associated with poorer mental health outcomes and reduced quality of life. Obesity is also associated with the leading causes of death in the United States and worldwide, including diabetes, heart disease, stroke, and some types of cancer.
Why is body mass index BMI an inaccurate measure of healthy body weight?
BMI (body mass index), which is based on the height and weight of a person, is an inaccurate measure of body fat content and does not take into account muscle mass, bone density, overall body composition, and racial and sex differences, say researchers from the Perelman School of Medicine, University of Pennsylvania.
