Last modified: Oct 12, 2022

Insurers may charge higher premiums when providing health insurance to obese people.  In some cases, health insurance for obese people may cost 25% to 50% more than coverage for those with a BMI below 30. Some insurers may even deny coverage for obese people. 

So we curated obesity statistics worldwide and in the United States. We will also cover obesity statistics by age, gender, and socio-economic status. 

Obesity Statistics —Top Picks 

Here are our top picks for obesity statistics around the world and in the United States. 

What Is BMI? 

The most common metric used for assessing obesity in an individual is the body mass index (BMI) scale. The World Health Organization defines BMI as “a simple index of weight-for-height that is commonly used to classify underweight, overweight, and obesity in adults.

It is defined as the weight in kilograms divided by the square of the height in meters (kg/m²).

For example, an adult who weighs 70 kg and whose height is 1.75 m will have a BMI of 22.9.” The measured BMI values determine whether an individual is underweight, healthy, overweight, or obese. These categories are defined by WHO using the cut-off points, which we will share in the table below. 

Classification BMI (kg/m2)
  Principal Cut-Off Points Additional Cut-Off Points
Underweight <18.50 <18.50
Severe Thinness <16.00 <16.00

How Much Does Obesity Cost the American Healthcare System? 

That is a staggering amount, and if obesity isn’t curbed, it will put a strain on the healthcare system. 

Obesity in America also impacts other costs that are harder to measure. Obese workers tend to miss more working days than healthy workers due to frequent health problems. Employers are also likely to pay higher worker’s compensation and insurance premiums for obese workers. Some studies have revealed that the wages of obese workers are lower than those of healthy workers. 

What Percentage of Children Are Overweight and/or Obese?

Childhood obesity is a pressing issue in the United States, which puts adolescents and children at risk of poor health later in life. Despite the threat, the prevalence of obesity among adolescents and children remains high all around the world. 

The only good news here is that obesity rates among preschoolers have been dropping recently.

That increases their risks of suffering from health complications and numerous other chronic diseases. 

The percentage of obese children has risen over the years, and if no steps are taken, it could spell disaster for the next generation of adults. 

There are currently more obese children and adolescents between 5 and 10 than ever. That’s why measures must be taken to reduce these numbers and improve children’s quality of life.  Breaking the age groups down further:

Age Group Obesity Prevalence
2–5 year-olds: 13.4%
6–11-year-olds: 20.3%
12–19-year-olds: 21.2%

Most parents think that their children look adorable when they put on a little weight, but there is a real risk of letting that get out of control. As a parent, you must inculcate healthy eating habits in your kids and ensure they get enough physical exercise

Childhood Obesity Prevalence by Race, According to Data Published by the CDC in 2017–2018:

Age Group Obesity Prevalence
Hispanic Children 25.6%
Non-Hispanic Black Children 24.2%
Non-Hispanic White Children 16.1%
Non-Hispanic Asian Children 8.7%

Obesity and COVID-19 

Obesity-related conditions worsen the effects of COVID-19, and it is harder to intubate patients with obesity. Ever since the start of the pandemic, numerous studies have reported that most of the sickest COVID-19 patients are obese or overweight. 

What Are the Common Health Effects of Obesity?

Being obese can hinder a person’s quality of life and lead to serious health problems like heart disease, sleep apnea, stroke, Type 2 diabetes, high cholesterol, cancer, and joint problems. Even though obesity isn’t a direct cause for any of these conditions, it increases the chances of suffering from health-related complications. 

This statistic points to the rising number of hospitalization cases in the United States when obese patients were admitted with serious health complications. 

There is a serious threat to your life if you suffer from obesity. The chances of obese individuals dying due to health complications are higher than those of healthy individuals. 

There are times when your lifestyle choices are not to be blamed for your obesity. Some diseases may cause obesity, including Cushing’s disease, hypothyroidism, polycystic ovary syndrome (PCOS), and insulin resistance. 

Around the world, obesity is one of the top five leading causes of death, contributing to nearly 3 million obesity deaths annually. The other leading causes are high blood glucose, tobacco use, physical inactivity, and high blood pressure. 

Researchers have found that men with waist circumferences in the highest 10% of measurements were 20 times more likely to develop Type 2 diabetes than others. Waist measurements can also help predict which people with low or normal weight may develop diabetes. 

It shouldn’t come as a surprise now, but being obese or overweight increases your risk of suffering from dozens of health complications and diseases. These diseases include cancer, heart disease, Type 2 diabetes, and stroke.
