Extremely obese teens take risks as peers do

A new study in the journal Pediatrics says high school students who are extremely obese engage in high-risk behaviors at rates similar to peers who maintain a healthy weight.

"Not only are they at health risk, but they also are typical teens and they're struggling with the same things that potentially other teens are struggling with," said senior study author Meg Zeller, from the Cincinnati Children's Hospital Medical Center, who also is an associate professor of pediatrics at the University of Cincinnati College of Medicine.

"We need to be talking about safe sex, drugs and alcohol with every teen and not assuming that this population is somehow not engaging in those behaviors," she said.

Researchers looked at data from a nationwide survey conducted in 2007 by the Centers of Disease Control and Prevention.  They compared 410 extremely obese high school students with 8,669 of their peers who had a healthy weight.  The measurement was the student's Body Mass Index, or BMI- a measurement which takes into account height, weight and gender.

An adolescent who had a BMI greater than or equal to the 99th percentile was considered extremely obese; those who had a BMI in the fifth to 84th percentile had a healthy weight.

The survey included specific questions about smoking cigarettes, the use of drugs or alcohol, sexual behaviors and thoughts of suicide.

The results showed the two groups had similar experiences, with few exceptions.

Zeller said the most surprising results involved sexual behavior.

"Our findings would suggest that teen girls who are extremely obese are less likely to have had sex- (that) was not surprising, but what was concerning was the fact that if they were sexually active, or had been sexually active, that it was more likely to be under the influences of substances," she said. "So it really paints this picture of vulnerability for this sub-population of teen girls and it really makes us question what their social interactions are really like."

In addition, both males and females in the extremely obese group were more likely to report having tried cigarettes. Extremely obese females were more likely to currently smoke and use smokeless tobacco.

Zeller noted that the study is part of research on bariatric surgery among these young people.

"We really need to understand the spectrum of health and mental health issues that these teens present with and how those things may change over time following a significant weight loss," she said.

"It's sort of adding another layer to the health and psychosocial risk for this sub-population of youth. They have type 2 diabetes, they have hypertension, they have sleep apnea, they have poor quality of life. These kids are suffering medically and psychosocially, and now we know that they're also engaging in high-risk behaviors. That could be a lethal combination."

    >14% of teens are at risk for heart disease, high cholesterol, and high blood pressure!
    >Obese Teens deal with social discrimination that's why they have low self esteem!

    Roca Labs Formula can help teens lose weight in a natural way. It has a gastric bypass effect that would occupy the stomach and leave a small space for food intake. Roca Labs Formula is rich in healthy fiber so it it safe for teens ages 12-18 years old to use.

    We are high risk for any disease when you are obese and teens aging 12-18 are at high risks. So what do we need to do to prevent this?We have to imply a specific diet plan for our kids that can help their eating and portion control. This roca labs formula is indeed a good source to help portion control to kids who are obese. I have several patients who have obese children and I am recommending this to them. This will cost them less and will have good results too.

    Obesity is really a big problem in our society today and all around the globe obesity is a major issue. My daughter is 16 years old and she is 200 lbs overweight. We went to our doctor and provided her a diet plan that can help her eating pattern and control her portions. Obesity can also lead to future complications like diabetes mellitus and hypertension. I am afraid she might suffer this in the future. I researched some weight loss programs in the past and this time I came across this Roca Labs Formula that helps you to feel full because of the fiber ingredients included. I bought one kit for my daughter and she is now on her 3rd month of using the formula. She lost a total of 20 lbs, though its not what I expected much from the product but I can see the difference and she loves her look. Her old clothes are now on her cabinet not being used much. We have to purchase new clothes for her. I recommend it to other mothers who has the same issue as mine.
