What is BMI and Global Health Observatory (GHO) data?

The BMI or Body Mass Index is a statistic that developed by Adolphe Quetelet in the first half of the 19th century for determining body fat. It uses the same bmi equation for male as female and kids.

By simple definition of bmi, a BMI or Body Mass Index is an essential measurement that helps you to monitor whether you are healthy, normal, overweight or obese. According to National Institutes of Health (NIH), Body Mass Index is a prestigious indicator that assists you to track body fat, and these fats are highly related to the risk of death and disease. You can calculate BMI with the ease of body mass index calculator online, and the entire calculation is based on your height and weight.

Global Health Observatory (GHO) data & BMI:

Situation and BMI Trends:

Minimum 2.8 million people estimated die each year worldwide who are prone to overweight or obese, and also it is estimated that 35.8 million (2.3%) of global DALYs (disability-adjusted life years) are caused by overweight or obesity. Study found that overweight and obesity lead to adverse metabolic effects on blood pressure, cholesterol, triglycerides and insulin resistance. Also, experts depict that risks of coronary heart disease, ischemic stroke, and type 2 diabetes mellitus increase steadily with increasing BMI. Remember that increased body mass index also raises the risk of cancer of the colon, breast, prostate, endometrium, kidney, and gall bladder. The GHO data depicts that mortality rate increase with increasing degrees of overweight, as determined by BMI.

If an individual want to achieve optimum health, then it is suggested that the median body mass index for an adult population should be within the range of 21 to 23 kg/m2, while the aim for individuals must have to be maintain healthy or normal bmi range 18.5 to 24.9 kg/m2. There BMI range 25.0 to 29.9 is associate with the risk co-morbidities and even moderate to severe risk of co-morbidities for BMI greater than 30 BMI range. So, try bmi calculator for adult (male and female).

Prevalence of obesity (Doubled):

In 2008, 35 percent of adults aged 20+ were overweight (BMI ≥ 25 kg/m2) (34% of men & 35% of women). Between 1980 and 2008, prveleance of obesity becomes doubled worldwide. In 2008, 10% of men (adult) and 14% of adult women around the globe were obese (BMI ≥30 kg/m2), compared with 5 percent of adult men and only 8 percent for adult women in 1980’s.The estimations found that around 205 million men and 297 million women over the age of 20 were obese – even a total of more than half a billion adults around all over the globe.

Prevalence of Overweight and Obesity (WHO Regions):

Yes, in the WHO regions of the Americas, the prevalence of overweight & obesity were highest, it is (62% are overweight in both male and female, and 26% for obesity) and the lowest in the WHO Region for South East Asia (14% overweight for both male & female and 3% for obesity). In the World Health Organization Regions including Eastern Mediterranean, Europe, and the Americas over 50 percent of women were overweight. For these three Regions of WHO (World Health Organization), roughly estimations are indicated as the half of overweight women is obese (23% in Europe, 24% in the Eastern Mediterranean, 29% in the Americas). In all World Health Organization Regions women were more likely to be obese than men. Women had roughly double the obesity prevalence of men in all the WHO regions for Africa, Eastern Mediterranean and South East Asia.

bmi overweight percentage

Studies depicted that the prevalence of increased BMI raises with income level of countries up to upper middle income levels. Also, the prevalence of overweight is double in the countries in which the high income and upper middle income than the countries in which low and lower middle income. When it comes to obesity, the difference becomes more than triples from 7 percent obesity in both men & women in lower middle income countries to 24 percent in upper middle income countries. The epidemic of obesity was significantly higher in women’s than men’s, with the exception of countries with high income where it has been similar. When it comes to low & lower middle income countries, approximately the obesity among women was double that among men.

Now, let’s take a look at the bmi formula for (adults) men and (adults) women.

What is BMI Formula and How to calculate it?

Here is the bmi calculation formula that helps you in calculating bmi, swipe down!

English BMI Formula:

For Pounds & Inches:

BMI = Weight (lb) / (Height (in))² x 703

When you considering English measurements or the above bmi equation, pounds should be divided by inches squared. And then, this should be multiplied by 703 to convert from lbs/inches² kg/m²

Metric BMI Formula:

For Kilograms and Meters (or Centimeters):

BMI = Weight (kg) / [Height (m)]²

The above bmi equation is demonstrated weight in kg divided by height in meters squared. If your height has been measured in centimeters, then you ought to divide it by 100 to convert this to meters.

Our bmi calculator for women and men also uses these above formulas to evaluating your bmi or body mass index. Account any one of the above formula to evaluate whether you have a healthy bmi or overweight, underweight, or obese.

How to Calculate BMI?

BMI Examples:

Calculate BMI With English BMI Measurement:

An example of calculating bmi by using the English system for the equation is:

What is my bmi, if:

  • My Weight is 150 lbs
  • My Height is 5’5” (65 inches)

Let’s put the value into the English formula for bmi:

BMI = 150 / (65)² x 703

So, your BMI is 24.96.

Calculate BMI With Metric BMI Measurement:

An example of calculating BMI using the metric measurement for the formula is:

Let’s take a look at an example of calculating body mass index by using the metric measurement for the formula:

Whats my bmi, if:

  • My Height is 165 cm (1.65m)
  • My Weight is 68 kg

Now, you ought to plug-in the values into the metric formula for body mass index:

BMI = 68 / (1.65)²

So, your bmi is 24.98

In general, once you determined your Body Mass Index measurement, you can easily find out if you’re at the risk for BMI Related Disease. Our bmi calculator female and male also uses the same body mass index formula to calculate body mass index for men and women.

Risks of being (high BMI) Overweight & Physically Inactive:

  • Respiratory disease
  • Digestive disease
  • Digestive diseases
  • Cancer
  • Osteoporosis
  • Compromised immune function

BMI for Children And Teenagers:

Body Mass Index or BMI for children and teens is said to be as age-and sex specific and typically indicated as BMI for age. You can find bmi for kids and teens by using the above bmi calculator with age and other parameters. For children, a high amount of body fat can leads can leads to certain helath-issues and weight-related diseases. Being underweight can also put your kids at risk for health problems.

Remember that the BMI ranges will remain the same for adults (women and men) throughout their life, but these figures are varying in children as kids are still at growing stage & do so at different rates. As an outcome, Body Mass Index or BMI is said to be a measure of weight for height as compared to the children of the same age. This entire bmi calculation results in BMI percentile. Our bmi percentile calculator works efficiently in determining child’s and teen’s bmi according to CDC growth charts.

For example:

If a kid is 14th year old (boy), his height is 5ft 3 inches tall and weighs 120 pounds, for instance, his body mass index or bmi is 21.3, mean this put him in the 75th percentile (take a look at the above table). This body mass index or bmi is said to be he has healthy weight as the proper range is between 90 and 120 pounds.

You can try our bmi percentile calculator that shows you proper bmi percentile for age chart and tells in which percentile category your teens and children falls.

Let’s take a look at this bmi graph to get a proper idea about BMI percentiles:

BMI Charts:

BMI charts play a crucial role in visualizing the ranges that are associated with each BMI category. Also, you can account them to locate your weight and height to calculate your bmi score and as well as the associated BMI category you fall within. Well, let’s first take a look at the bmi chart for men and women.

What is a BMI percentile and how is it interpreted?

Once bmi is calculated corresponding to teens and child age, it is expressed as “Percentile”, it does not matter either it is obtained from bmi percentile graph or bmi percentile calculator for kids and teens. These percentiles are measure that is expressed a kid’s bmi or body mass index relative to U.S children; they are participated in the national surveys from 1963-65 to 1988-94. Optimistic studies depict that height and weight change during the growth and development as they both are related to body fatness. Consequently, a child’s body mass index (BMI) should be interpreted relative to the other children of the same age and gender.

In the United States (U.S), the bmi for age percentile growth charts is said to be the most typical used indicator to determine the size and growth patterns of children and teens. Our bmi calculator for children also measure kids and teenagers bmi corresponding to the bmi for age percentile growth charts.

Let’s take a look at the bmi-for-age percentile growth chart:

Weight Status Category Percentile Range
Underweight Less than the 5th percentile
Normal or Healthy Weight 5th percentile to less than the 85th percentile
Overweight 85th to less than the 95th percentile
Obese Equal to or greater than the 95th percentile

Is BMI interpreted the same way for children and teens as it is for adults?

BMI is interpreted differently for the children and teens as it is for adults. In fact, BMI for children and teens need to be age and sex-specific as the amount of body fat changes with age and the amount of body fat differs between boys and girls. The CDC or Centers for Disease Control and Prevention BMI-for-age growth charts take into account these all difference & visually demonstrate BMI as a percentile ranking.

What is the Body Mass Index Used for?

Yes, the BMI is something that was over 150 years old, some major health authorities like the CDC (Centers for Disease Control and Prevention) and National Institutes of Health (NIH) in the U.S still believe that “BMI is reliable indicator of body fatness for most people.” So, the above calculator for body mass index is taken into account to determine bmi for female and male, kids and teens.

Public Health Statistics:

Even current days, Body mass index is used as the official measure of national obesity rates. For instance, for the obesity epidemic, the Union European Union continues to use BMI as a yardstick and even suggests that individuals with higher bmi are a greater risk of diseases that includes hypertension, cancer, and cardiovascular disease.

The Harvard T.H. Chan School of Public Health depicted that your risk of developing conditions like type-2-diabetes increases progressively as your Body Mass Index rises above the range 21. The ranges of bmi kids and teens are varying, to get body mass index chart for kids and teens, simply plug-in the values into the above smart bmi tool and get the results within couple of seconds.

Weight Range Analysis:

Also, the bmi range considered to be an accurate measure of an individual weight range. Thus, if an individual have a bmi of 27, then he/she said to be overweight regardless of what he/she actually weigh and his/her body composition or gender is not taken into account.

Screening Tool for Weight Problems:

If your health care provider calculate a higher than normal BMI, then the very next step is to see if you’re at risk of certain health-related problems. In fact, the basic role of Body Mass Index or BMI is to evaluate whether you’re likely to develop a serious medical problem later in your life.

For instance, in France, BMI is work as a screening tool for child malnutrition. The CDC bmi chart for kids and teen and the BMI scale is said to be an effective means of determining whether the teenagers and children are healthy weight, underweight, overweight, or obese.

Fashion Industry:

When it comes to fashion’s industry, there obsession with exceedingly thin models has ensured that the Body Mass Index calculator for women is the tool that has a permanent home there. The fashion industry is continually under fire for forcing females, typically, to achieve what the UK Women’s Equality party calls “yes, an unattainable level of thinness in females” The party has invited on all the models with a Body Mass Index below 18.5 to be seen by a medical PRO from an accredited list who will decide if than female is enough health to work!

Additionally, there is a law to that has impact in Israel where man and woman models with a BMI below the 18.5 much get a medical certificate of confirming a ‘normal’ BMI reading. For instance, you can take a look at the Kate Moss (one of the most famous models ever), she only had a BMI of just 15 at the height of her fame. By any evaluation, including Body Mass Index, Kate was severely thin!

Global BMI Statistics vs. USA:

No doubt, Body Mass Index or bmi measurements are varying around the world and only few nations have greater ‘obesity’ problems than others according to the bmi scales. Let’s take a look at the global bmi scores, here we are going to complied statistics from 6 regions globally. First of all, here you come to know about the average body mass of individuals in different continents expressed in KGs or kilograms:

Region Average Body Mass (KGs)
Asia 57.7 kg
Africa 60.7 kg
Latin America / Caribbean 67.9 kg
Europe 70.8 kg
Oceania 74.1 kg
North America 80.7 kg
Global Average 62.0 kg

From the above-average body mass KGs Asians people are significantly lighter than Americans while they’re tool shorter on average; it is evident that individuals in North America have a higher BMI figure! Also, try this bmi calculator kg to attain average body mass KGs measurements!

BMI Statistics in USA:

The United States (U.S) has the highest Body Mass Index average around the globe behind Kuwait. America’s 28.8 averages is just behind Kuwait’s 29.5 and even said to be a major problem in the American society.

Average BMI of American Males:

Studies depict that American males have the second highest average Body Mass Index around the globe with 28.5, slightly behind the “Argentina” which is number 1 at 28.7.

Average BMI of American Females:

In the United States, the average bmi of females is even higher than in makes at 29.0 although disturbingly, there are different nations those with higher averages that including Kuwait, Trinidad and Tobago, and Egypt.

Obesity Rates in the USA:

In the USA, estimates for obesity varies but according to the World Obesity Federation (the platform from where we have gleaned obesity statistics from every country on the list), around 41.5 percent of women aged 20 plus were obese, and only 37.9 percent adult males.

Possible Limitations of the BMI:

BMI is said to be a useful tool for determining healthful weight, but experts have depicted uncertainty about BMI’s reliability. Remember that when it comes to analyze body fat, BMI is not an accurate measure!

  • Body Mass Index measures overall nutritional status corresponding to relation of height and weight. However, no mention of body fat percentage or muscle mass
  • Also, BMI is not something that distinguish water weight, bone mass etc
  • BMI is not specific to sex of an individual. For instance, Body Mass Index of female and male is same whereas male contains more muscle mass & female has more fat mass which is not mention in Body Mass Index or BMI Chart

Other Body Fat Measurement Methods:

You can find different methods of assessing the percent of fat and lean mass of a person. These are the methods that said to be as a body composition analysis. Well, some of the most common measurements are mentioned below:

  • Underwater weighing: This procedure is also referred to as hydrodensitometry, no doubt, this method is complex and enough complicated, so it is rarely used
  • Skinfold thickness measurements: This is the method that is taken into account by many experts as this is the simplest method to determine body composition
  • Bioelectrical impedance: The one of the most common methods of assessing body fat percentage that assists to determine total body weight, muscle mass, the percent and amount of body fat, water, and even bone mass. Remember that the readings can be affected by hydration level and different other factors, they fairly provide accurate results over time.

BMI Stages of Development:

Remember that regular BMI cannot accurately indicate the state of an individual’s health at some stages in life.
These are:

  • Pregnancy and Breastfeeding
  • Childhood and Adolescence, (while an individual is still growing)

That’s the reason why bmi calculations are varying for children and teens. These are the measurements that take age and gender into account to calculating bmi. Our bmi percentile calculator also shows the results in percentile CDC growth charts according to age and gender of your child’s or teens.

Also, norm can vary among individuals of certain races and ethnicities.

Making BMI Accurate:

The (NHLBI) or National Heart, Lung, and Blood Institute depicts that an assessment of weight and health risks should incorporate three key measures, these are:

  • BMI
  • Waist Circumference
  • Risk factors for diseases and conditions associated with obesity (Class 1, 2, 3)

Waist circumference:

If fat accumulates around the waist rather than the hips, an individual may have a higher risk of heart disease & type-2 diabetes.

The Centers for Disease Control and Prevention (CDC) reveals that this risk increases with a waist size greater than 35 inches for non-pregnant females or greater than 40 inches for men!

To measure the waist:

  • You ought to place a tape measure around the middle, or just above the hip bones and the navel
  • You have to take the measurements just after breathing out

Weight, obesity, and health risks:

The given information are adapted from the (NHLBI) or National Heart, Lung, and Blood Institute, which may assists indicate the risks associated with Body Mass Index or BMI and waist circumference.

The given chart provides you with the weight categories that are corresponding to BMI, and the along with the effects of higher waist circumference on the risks of cardiovascular disease, hypertension, and type 2 diabetes.

Classification BMI (kg/m2) Obesity class

Waist

Waist

     

Men 40 inches or less

Women 35 inches or less

Men: 40 inches or more

Women: 35 inches or more

Underweight 18.4 or less      
Healthful weight 18.5–24.9      
Overweight 25.0–29.9   Increased risk High risk
Obesity 30.0–34.9 I High risk Very high risk
  35.0–39.9 II Very high risk Very high risk
Extreme obesity 40.0+ III Extremely high risk Extremely high risk

Also, the following issues can increase the risk of developing heart disease, for instance:

  • High Blood Pressure (Hypertension)
  • High Levels of low-density lipoprotein (“bad”) cholesterol
  • low levels of high-density lipoprotein (“good”) cholesterol
  • high levels of triglycerides
  • high blood sugar levels
  • A family history of early heart (cardiovascular )disease
  • physical inactivity
  • cigarette smoking
  • a high consumption of alcohol
