More than two-thirds of U.S. adults and almost one-third of children and adolescents are overweight or obese. Obesity is a complex metabolic disease with many contributing factors.

More than two-thirds of U.S. adults and almost one-third of children and adolescents are overweight or obese. There are many factors that contribute to obesity.  Neighborhood design, access to nutritious, affordable foods and beverages, and access to safe and convenient places for physical activity can all impact weight and health.  The racial and ethnic disparities in obesity underscore the need to address social determinants of health such as poverty, education, and housing to improve health equity.

Obesity is a major public health concern in the United States as it is a contributing factor to many diseases including heart disease, stroke, diabetes, and some types of cancer.

Contributors to obesity in adults and children may include:

Childhood Obesity

Childhood obesity is a serious problem in the United States putting children and adolescents at risk for poor health throughout their lives. Obesity is defined as a BMI at or above the 95th percentile for children and teens of the same age and sex. Today, more and more children are being diagnosed with diabetes, hypertension and other co-morbid conditions associated with obesity and severe obesity.

Body Mass Index

Obesity is defined as having excess body fat. Body Mass Index (BMI) can be used to screen for weight categories that may lead to health problems, but it is not diagnostic of the body fatness or health of an individual.  BMI is a person’s weight in kilograms divided by the square of the body height.

To estimate your BMI, see the Adult BMI Calculator or determine BMI by finding your height and weight in this BMI Index Chart.

To estimate a child or teen’s Body Mass Index (BMI), type height and weight into the Child and Teen BMI Calculator

Asthma is a chronic condition that causes wheezing, breathlessness, chest tightness and coughing at night or early in the morning. If people with asthma are exposed to a “trigger” the symptoms can become more severe.

Asthma Triggers include:

Asthma cannot be cured. However, by eliminating asthma triggers and taking asthma medication, you may be able to reduce the frequency of your asthma attacks. Treatment varies from person to person, so it is important to work with your doctor to manage your asthma and create an asthma action plan.

Arthritis is inflammation of one or more of your joints. The main symptoms of arthritis are joint pain and stiffness, which typically worsen with age. People of all ages, sexes and races can get arthritis, but it is most common among women and occurs more frequently as people get older.

There are many types of cancer. While cancers are alike in some ways, they are different in the ways they grow and spread. There are several factors that can put you at an increased risk of developing cancer. These include using tobacco products, sun exposure, being overweight or obese, and drinking too much alcohol.

Knowing the cancer history of your family is also important to understanding your potential risk for cancer so you can take charge of your health.

The signs and symptoms of cancer depend on where the cancer is, how big it is, and how much it affects the organs or tissues. If a cancer has spread (metastasized), signs or symptoms may appear in different parts of the body. Just as the signs and symptoms can vary, the treatment options for everyone will vary as well.
The good news is that you can decrease your risk of preventable cancer by making healthy lifestyle choices like:
