As many as 80% of adolescents with obesity will continue to have obesity as adults.1* Adolescent obesity may increase the risk of developing certain weight-related conditions.3
*Based on a meta-analysis of 15 prospective cohort trials, including individuals aged 7-18 years in which BMI values were recorded from childhood into adolescence or adulthood.1
BMI, body mass index.
Adolescent obesity
Adolescent obesity may increase the risk of developing certain weight-related conditions3
Among youth in the US4†:
Since 1970s
†Data of individuals aged 2-19 years from the National Health and Nutrition Examination Survey (NHANES).4
Weight-related conditions typically observed in adults are being seen in adolescents with obesity, including3,5:
While usually developing in people older than 45 years, type 2 diabetes is increasingly developing in adolescents and young adults.6
A large epidemiologic cohort study encompassing over 12,000 participants aged 10-18 years in the US prospectively assessed the risk of adult obesity using childhood BMI, finding that adolescents with BMIs above the 85th percentile are more likely to have obesity in adulthood compared to their normal weight counterparts.2
There is an adolescent obesity epidemic in the US3
The obesity prevalence among adolescents aged 12-19 years in the US is 22.2%.7 Severe obesity is defined as having a BMI that is 120% of the 95th percentile or greater, or a BMI of 35 kg/m2 or greater.8 Obesity in adolescence is classified as having a BMI value at the 95th percentile or higher for age and sex, and overweight in adolescence is classified as being at or above the 85th percentile for age and sex.8 Since many adolescents with obesity go on to become adults with obesity, adolescence may be a critical time to address their excess weight.3
Because obesity is a chronic disease that often has associated comorbidities, long-term strategies, ongoing monitoring, and treatment may be required. Obesity management—including health-behavior coaching, lifestyle-modification plans, pharmacotherapy when indicated, and, for those patients aged 13 years and older with severe obesity, bariatric surgery evaluation—should be considered.3
Elevated risk for some adolescents
Certain adolescents may be at higher risk for obesity3
Factors that are associated with increased prevalence of obesity among adolescents include:
Having parents with obesity3
Certain ethnic backgrounds—eg, Hispanic, or non-Hispanic Black3,9
Lower-income households3
Lower head-of-household education level9
Finally, obesity rates may be affected by the types of food adolescents eat. Fast-food consumption, lack of access to fresh food, and sugar-sweetened beverages have been associated with obesity in children.3
Social impact
Obesity can have a negative social impact on adolescents3
Adolescents—whether living with obesity or not—are constantly navigating challenging social circumstances. In simple terms: being a teenager isn't easy.
Part of assessing the overall health of adolescents with obesity is to determine if their weight challenges are affecting their emotional health. Adolescents with obesity may experience weight stigma, teasing, and bullying. They may feel social isolation, have reduced physical activity, or even avoid seeking help from a health care professional for their weight.3
When speaking with your adolescent patients, keep in mind the weight stigma and bias they may have experienced in previous health care interactions. Acknowledging their experiences and speaking to them and their caregivers from a place of understanding can help improve relations between the patient, family, and health care team.3
Don't hesitate to ask your adolescent patients if they have experienced teasing or bullying based on their weight, and remember to suggest available resources at stopbullying.gov or refer them to counseling.3

There may be a disconnect between HCPs and adolescents with obesity and their families
In a global study of 5,275 adolescents with obesity who completed an online survey about their weight10†:
Percentage of adolescents getting their information about weight management from YouTube.10
Percentage of adolescents getting their information about weight management from other social media.10
Percentage of adolescents getting their information about weight management from their HCPs.10
Acknowledge how complex obesity is and the difficulty that may be encountered in trying to maintain a healthy weight. Also, it is helpful to utilize people-first language, such as saying “adolescents with obesity” instead of “obese adolescents.”3
It is imperative to also evaluate your adolescent patients for potential disordered eating or unhealthy weight-control behaviors and to use the clinical measures taken at annual health visits to see if any of them signal the presence of an eating disorder.3
†Based on data from a cross-sectional, survey-based global study aimed to identify perceptions, attitudes, behaviors, and barriers to effective obesity care among adolescents with obesity (n=5,275), their caregivers (n=5,389), and their HCPs (n=2,323). Participants were residents of the following 10 countries: Australia, Colombia, Italy, Mexico, Saudi Arabia, South Korea, Spain, Taiwan, Turkey, and the United Kingdom.10
HCP, health care professional.
Caregiver conversations
How caregivers approach the subject of weight is important3
The subject of weight and body image can be sensitive for adolescents.3 An important first step for health care professionals like you is to help caregivers understand and accept that their child has obesity and recognize the potential implications.11 In fact, when caregivers talk to children about weight, it is important to emphasize healthful eating.9
In a global survey of 5,389 caregivers of adolescents with obesity, 34% believed their child’s weight to be normal or below normal.10† Educating them about how increased BMI in younger patients relates to obesity in adulthood might help caregivers understand the potential risks of adolescent obesity2:
Avoid conversations that increase weight stigma3
Try to talk about the positives of healthful eating and physical activity11
HCPs play a critical role in helping parents and caregivers understand weight management3
It is not only on the shoulders of HCPs to help adolescent patients manage their weight. Studies have shown that medium- to high-intensity involvement within the family was associated with improved weight management. By providing support and being positive role models, parents and caregivers can help adolescents develop healthier behaviors for their weight.
