Height and Growth Velocity in Children and Adolescents Undergoing Obesity Treatment: A Prospective Cohort Study
Authors' conclusion
Obesity severity is positively associated with height and growth velocity in childhood. A hampered growth spurt during puberty should be anticipated, particularly in adolescents with severe obesity. Therefore no difference in final height between class I and class II obesity is expected. Successful obesity treatment does not harm, but rather normalizes, the growth velocity pattern.
Study context
- Population
- Children aged 3–18 years enrolled in BORIS (1998–2020); mean age 10.2 ± 3.6 years
- Participants
- 27,997 children
- Exposure
- Class II vs class I obesity; good vs poor obesity treatment outcome
- Outcome
- Height for age z score, final height and growth velocity by obesity class; growth velocity by obesity treatment outcome
- Follow-up
- 2-year follow-up
Methodological detailsregistry-based (Swedish Childhood Obesity Treatment Register, BORIS)

Main finding
As reported in the abstract
- Class II obesity on average taller than class I obesity during childhood
- Males: reduced growth spurt in class I obesity, absent in class II obesity
- Females: similar but less pronounced pattern
Observational data: associations, not effects.
Further findings
Growth velocity by obesity treatment outcome · 2-year follow-up
- Good vs poor treatment outcome: lower growth velocity at ages 3 to 9 years but higher at ages 10 to 13 years
