BMI is an estimate of body fat and a good gauge of your risk for diseases that can occur with more body fat. The higher your BMI, the higher your risk for certain diseases such as heart disease, high blood pressure, type 2 diabetes, gallstones, breathing problems, and certain cancers.
Is BMI a good health indicator?
BMI is a useful indicator of health at the population level. However, the distribution of fat on your body is more important that the amount, when assessing your disease risk. For this reason, your waist circumference is thought to be a better predictor of health risk than your BMI.
Is BMI a valid predictor of health risk?
Furthermore, studies have shown that BMI levels correlate with body fat and with future health risks. High BMI predicts future morbidity and death. Therefore, BMI is an appropriate measure for screening for obesity and its health risks.
Is obesity a disease or a risk factor?
Obesity is a complex disease involving an excessive amount of body fat. Obesity isn’t just a cosmetic concern. It is a medical problem that increases your risk of other diseases and health problems, such as heart disease, diabetes, high blood pressure and certain cancers.
Is BMI a good indicator of heart disease?
In the studied population, it is observed that BMI is significantly associated with blood pressure indices and, therefore, is a good indicator of cardiovascular risks.
Is WHR a better indicator than BMI?
WHR is an easy, inexpensive, and accurate way to see how much body fat you have. It can also help predict your risk for heart disease and diabetes. A few studies suggest that WHR is even more accurate than BMI for predicting the risks of cardiovascular disease and premature death .
What is the best BMI for a woman?
A BMI of 18.5–24.9 is considered normal or healthy for most women.
Does BMI actually matter?
As a single measure, BMI is clearly not a perfect measure of health. But it’s still a useful starting point for important conditions that become more likely when a person is overweight or obese.
Why is BMI not a good health indicator?
BMI is not an accurate predictor of health because it does not account for body fat percentage or body fat distribution. In addition, BMI cannot accurately predict the health of different demographics and races because it was created with data from only white Europeans.
Why is BMI not accurate for elderly?
You can’t tell between fat, muscle or fluid mass so using BMI may not be accurate. For the elderly, muscle mass is much lower in comparison to fat mass, and many have medical conditions that can increase fluid mass as well.
Who is most at risk of obesity?
The latest National Health Survey shows that men are more likely to be overweight or obese than women (74.5 % compared with 59.7% respectively). Men and women living in regional and remote areas of Australia are more likely to be overweight or obese than men and women living in major cities.
Why is obesity considered a health risk?
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.
What increases the risk of obesity?
Lack of physical activity, unhealthy eating patterns, not enough sleep, and high amounts of stress can increase your risk for overweight and obesity.
Does waist size go up with height?
Like the waist-hip ratio, a waist-height ratio looks at waist size in relation to — you guessed it! — your height. Ideally, your waist measurement should be less than half of your height. (So if you’re 5 foot 6, or 66 inches, your waist circumference should be less than 33 inches.)
What should a healthy waist size be?
For your best health, your waist should be less than 40 inches around for men, and less than 35 inches for women. If it’s larger than that, you may want to talk with your doctor about what your next steps are, including losing weight. You can’t spot-reduce your waist, or any other part of your body.
