Childhood and Teenage Obesity: Partnering with Your Pediatrician

Reviewed By:

You want the best for your child, including a healthy body and strong self-esteem. If you think your child might be overweight, it’s important to discuss the matter with your pediatrician.

Sheila Ravendhran, M.D., M.P.H., a pediatrician with Johns Hopkins Community Physicians, has special certification in addressing obesity. Ravendhran regards parents as partners working with her to support their child’s well-being.

She works to help parents understand the implications of weight in their child’s health, noting, “The doctor and the parents need to be united in wanting what’s best for kids.”

Obesity: A Real Health Risk for Children and Teens

In the United States, over 18% of children age 2 to 19 are living with obesity, including 13.9% of children under 6. Obesity is more common in certain populations, including Hispanic and black children, children from middle income families, and those growing up in homes headed by adults with lower education levels.

Health care professionals are seeing earlier onset of type 2 diabetes, heart and blood vessel disease, and obesity-related depression and social isolation in children and teens. The longer a person suffers with obesity, the more significant obesity-related risk factors become.

Is my child obese?

How easy is it to diagnose the condition in children? “Actually, it’s really hard,” Ravendhran says. “Studies show that parents, physicians and nurses have trouble looking at a child and predicting their body mass index.”

Body mass index, or BMI, is a number based on the ratio between a person’s weight and height. For adults, a BMI above 25 means the person is overweight.

But, Ravendhran says, BMI doesn’t necessarily define obesity in children the same way it does in adults. Looking beyond the number itself, she says that if a child’s BMI is higher than 95% of other kids who are the same age and sex, that gets her attention.

“There are lots of different ways to define and diagnose obesity, and what works for adults may not be applicable to kids, since their body composition changes,” Ravendhran says.

“For instance, measuring fat on the upper arm doesn’t work for very young children: Babies and toddlers are supposed to be fat. On the other hand, I’ve learned that it is pretty normal to be able to see ribs on kids aged around 4 to around 7. If a parent is noticing an expanding waist circumference or creases or rolls in the belly, chest or back in a child over 4, then I’d be concerned.”

“I counsel parents the same way, no matter where the kids are on the chart. I look at the current diet, genetics and other factors. If a child’s numbers show they’re at risk, I make it clear to the parents that there’s not anything wrong with the child, but we might discuss some interventions to head off health issues later on.”

Treatment for overweight kids: What can parents expect?

If your child’s BMI meets the criterion for obesity, do they have to go on a weight loss diet? Not necessarily, Ravendhran says. She explains there are reasons to proceed cautiously when helping children and teens lose weight.

And underlying mental health issues can spark an eating disorder in vulnerable kids. “Sometimes it’s a slippery slope,” she says. There aren’t a lot of evidence-based data on teenage weight loss regimens, since people under age 18 are not allowed in most studies.

“Treatment goals are different for kids at different ages,” she says. “For instance, for younger kids, the goal is weight maintenance, not loss, since they’re getting taller.” Rapid weight loss can effect changes in metabolism, with an impact on a child’s growth and learning ability.

For teenagers, Ravendhran may prescribe a gradual weight-loss regimen aiming for loss of about 2 pounds a month. However, in severe situations, some kids may need more urgent help. If there are co-existing problems — such as asthma, type 2 diabetes or cardiac findings, Ravendhran says, she will consider bariatric (obesity-addressing) surgery, such as a gastric sleeve procedure

How can parents support their kids’ healthy weight?

“It’s hard for parents to know what to do when there’s so much disinformation out there,” Ravendhran says. “Snacks and foods marketed for kids are high in refined and processed carbohydrates and sugar, which, over time, can take a toll on the body’s sensitivity to insulin. These foods act on the brain’s pleasure centers while suppressing the sensation of fullness,” she says.

Ravendhran suggests that parents bring their child in for well- child checks as often as the pediatrician recommends. At these visits, parents can ask about their child’s health and nutrition.

Kids, Screen Time and Exercise

Staying active is key to maintaining a healthy weight, and the sedentary time kids spend on computers, tablets and phones should be limited. Ravendhran says, “We recommend less than two hours a day of screen time for children over 5. Two- to 5-year-olds should get less than one hour a day, and if they’re under 2, there should be no screen time at all.”

As far as exercise, Ravendhran says that mild to moderate activity is essential for all children, regardless of weight. Children diagnosed with obesity can and should exercise, she adds, but for vigorous activities she advises getting physician clearance first to ensure their safety.

“At least an hour a day is recommended,” she says, “and obese children may actually need more. It takes 40 minutes of fast walking for a child to burn off the calories in one juice box,” she notes. 

One Simple Step for Tackling Obesity

Speaking of juice boxes, according to Ravendhran, one simple and effective measure in helping kids control their weight is to cut out sugary drinks. Sodas, power drinks and smoothies are very high in sugar, which can add hundreds of calories to a child’s daily intake.

Fruit juice is also a no-no. “Parents look surprised when I say ‘No juice,’ but a glass of orange juice, store-bought or fresh squeezed, has the sugar of six to eight oranges. The processed kind may not have any fiber.” She recommends kids eat a piece of whole fruit instead.

“In the past 10 years we’ve seen a decline in obesity among young kids,” Ravendhran notes. “Limiting sugar-sweetened beverages, taking the vending machines out of schools and not promoting fruit juice is having an impact.”

Supporting Kids’ Mental Health When Discussing Obesity

Ravendhran says she’s especially careful with language and encourages parents to watch their words as well.

“According to research, kids living with the stigma of being ‘overweight’ or ‘obese’ have a quality of life score that’s equivalent to that of kids living with cancer,” she notes.

Mental health is an important part of the treatment plan. She works with parents to promote children’s relaxation and stress reduction, which she says has a positive effect on the child’s well-being and a physiological benefit on their insulin levels. “Positive self-care and feeling good are great interventions for children’s general health and weight control.”

With that in mind, Ravendhran is excited about the impact of yoga, which she teaches at her kids’ school. Not only is yoga good for stress, but it’s also a way for kids to exercise.

“I’m looking at yoga and mindfulness training to break down some of the barriers that keep kids from being physically active,” she says. “I like yoga because it’s not competitive. There’s no judging or expectation.”

“It’s about what feels good in the moment and being thankful for the body you have.”
