Is OBESITY Trending Up Or Down?

March 18, 2023 2 min read

Obesity has become a major health concern in many countries, including the United States. According to the Centers for Disease Control and Prevention (CDC), over 42% of American adults are obese, and the number continues to rise. However, in recent years, there has been some debate about whether obesity rates are increasing or decreasing. In this blog post, we will examine the evidence to determine the current trend in obesity in the United States.

First, it is important to understand how obesity is defined. The CDC defines obesity as having a body mass index (BMI) of 30 or higher. BMI is calculated by dividing a person's weight in kilograms by their height in meters squared. While BMI is not a perfect measure of body fat, it is widely used as a screening tool for obesity.

Now, let's look at the evidence. In the early 2000s, obesity rates in the United States were on the rise. From 1999 to 2010, the prevalence of obesity among adults increased from 30.5% to 36.1%. However, since then, there has been some evidence to suggest that obesity rates may be leveling off or even decreasing.

A 2016 study published in the Journal of the American Medical Association found that overall obesity rates among adults in the United States had not significantly increased since 2003-2004. However, the study did find that there were significant increases in obesity rates among certain populations, including women, African Americans, and those with lower income and education levels.

Another study published in JAMA in 2018 found that obesity rates among children and adolescents in the United States had remained stable in recent years. However, the study did find that severe obesity rates (defined as a BMI of 40 or higher) had continued to increase among children and adolescents.

While there is some evidence to suggest that obesity rates may be leveling off or decreasing in certain populations, it is important to note that obesity remains a significant public health issue in the United States. Obesity increases the risk of many chronic diseases, including type 2 diabetes, heart disease, and certain types of cancer. Therefore, it is important for individuals to maintain a healthy weight through diet and exercise, and for public health officials to continue to implement policies and programs aimed at preventing and reducing obesity.
