Later puberty is linked to greater body dissatisfaction in boys, while earlier puberty is associated with lower body dissatisfaction in girls. These findings suggest a need for interventions addressing adolescent body image concerns.
Area of Science:
- Adolescent health
- Developmental psychology
- Public health
Background:
- Early puberty is associated with body dissatisfaction, but research is limited.
- Previous studies lacked objective measures and focused on girls.
Purpose of the Study:
- To investigate the association between pubertal timing and body dissatisfaction in mid-adolescence.
- To examine objective measures of pubertal timing: age at peak height velocity (aPHV) and age at menarche (AAM).
Main Methods:
- Prospective cohort study of 6644 UK adolescents (41% male).
- Measured body dissatisfaction and self-image at age 14 using validated scales.
- Used multivariable regression, adjusting for socioeconomic status and prepubertal BMI.
Main Results:
- Later aPHV in boys correlated with higher body dissatisfaction.
- Earlier age at menarche (AAM) in girls correlated with lower body dissatisfaction.
- Later aPHV in girls was linked to better self-image, but this effect was moderated by BMI.
Conclusions:
- Pubertal timing significantly influences adolescent body image.
- Findings underscore the need for tailored interventions for body dissatisfaction.
- Further research should explore BMI's role in mediating these associations.
