Why Childhood Obesity Can Be a Long-Term Concern – Health Essentials

Obesity doesnt just bring immediate health concerns for children with excess body fat. It brings worries for the future, too.

Early obesity establishes a pattern that can lead to a lifetime of weight and health challenges. Kids who carry extra pounds are more at risk of developing chronic, life-altering medical conditions as they grow up.

At the moment, thats a stark reality of whats ahead for more than 160 million young people around the world living with obesity. That figure includes more than 14.7 million children in the United States.

These numbers continue to grow, too, fueling talk of an obesity epidemic among our youngest generation. Childhood obesity now qualifies as the most common chronic disease affecting youths.

To learn more about the long-term consequences of this trend, we turn to Lina Alkhaled, MD, a specialist in pediatric obesity.

So, when is a kid considered to have obesity or overweight? Thats an assessment made using body mass index (BMI) plus a BMI-for-age-and-sex growth chart, according to Dr. Alkhaled. (BMI uses a ratio of height and weight measurements to estimate body fat.)

Children whose BMI places them in the 95th percentile or above on the growth chart are considered to have obesity. Placement in the 85th to less than the 95th percentile qualifies as experiencing overweight.

Using the chart makes the determination process different from the BMI-only method used for adults without regard to age or sex.

There is not an absolute BMI number that defines obesity in children, clarifies Dr. Alkhaled. Instead, we plot the BMI value on certain curves for males and females. Based on where that point lands, we can define obesity or overweight.

It should be noted, too, that obesity is a complex chronic disease. Many factors including genetics and socioeconomic status contribute to why some children gain more weight than others. Its often not as simple as just food intake and activity levels.

No matter the cause or reason behind an obesity diagnosis, excess fat can bring associated health complications. Those extra pounds strain a body while forcing it to work harder to function.

As one group of researchers eloquently put it, obesity serves as the soil for the development of other diseases. Here are a few of those potential health risks.

Excess weight can take a toll on the heart, forcing it to work harder to circulate blood around a larger body. Obesity can also fuel heart disease risk factors such as high blood pressure (hypertension) and high cholesterol.

Early obesity increases the risk of heart issues later in life. A 2023 study found that kids with higher BMI are 40% more likely to experience cardiovascular disease in adulthood.

Those same researchers reported that children with multiple obesity-related risk factors such as high BMI, high blood pressure or high cholesterol could have up to a nine-times greater risk of a heart attack or stroke.

When you tie all of these factors and complications together, they can lead to heart diseases in the future, says Dr. Alkhaled. Theyre very closely linked.

Your body breaks down the food you eat into glucose (sugar) to provide the energy you need to power through the day. Insulin, a hormone made in your pancreas, plays a key role in regulating this process.

Obesity can lead to insulin resistance, meaning your body doesnt respond as it should. This can lead to high blood sugar levels (hyperglycemia) and the development of diabetes.

Increases in diagnoses of childhood diabetes have mirrored the rise in obesity, notes Dr. Ahlkaled. Research shows that children with obesity are more likely to develop lifelong diabetes than those with lower BMIs.

Early-onset diabetes also increases the risk of heart disease, as well as complications like kidney disease, eye disease and nerve damage.

Obesity at an early age creates an inflammatory environment that appears to suppress a bodys ability to ward off cancer later in life. Studies show that higher BMI during childhood may increase the risk of:

Overall, theres a strong connection between obesity and cancer. The U.S. Centers for Disease Control and Prevention (CDC) reports that obesity and being overweight elevate the risk for 13 different kinds of cancer.

Carrying extra weight doesnt just take a physical toll on a person. Theres a mental one, too.

Research shows that children with obesity are 32% more likely to have depression than children at a healthier weight. This elevated risk of depression carries over into adulthood, too, says Dr. Alkhaled.

Excess weight can also lead to low self-esteem, eating disorders and social anxiety in children, which can become lifelong issues.

It has been found that children with obesity may have a very poor quality of life, even poorer than kids with cancer, shares Dr. Alkhaled. It can have a very negative impact on mental health.

Many of the health issues noted here arent just because of early-in-life obesity. Often, theyre a byproduct of continued obesity into adulthood.

Consider these study findings:

But its important to note that these statistics arent destiny: Children who attain a healthier weight before adulthood usually have similar health outcomes to those who never had obesity, says Dr. Alkhaled. Managing obesity early can help prevent future complications.

Guiding children with obesity toward a healthier weight begins with encouraging lifestyle changes, says Dr. Alkhaled. Positive steps include:

If lifestyle adjustments dont bring changes, talk to your childs healthcare provider about options such as medications that can help manage obesity.

Talk to your child openly about obesity, too, and explain how making changes is about being healthier in the present and future. Avoid blaming or shaming language or focusing too hard on weight numbers.

Address obesity from a health standpoint, advises Dr. Alkhaled. Explain to your child what they can do to feel more energized during the day, sleep better at night and live a healthier and hopefully longer life.
