Weight gain since infancy and prepubertal body dissatisfaction

Area of Science:

• Pediatric Health
• Developmental Psychology
• Body Image Research

Background:

• Understanding the origins of body dissatisfaction is crucial for early intervention.
• Prepubertal body image development is influenced by various factors, including physical changes.
• Longitudinal studies provide valuable insights into developmental trajectories.

Purpose of the Study:

• To examine the association between body dissatisfaction in prepuberty and changes in relative weight since infancy.
• To determine if weight gain patterns precede the development of body dissatisfaction.
• To investigate gender differences in this association.

Main Methods:

• Longitudinal cohort study tracking weight and height from 7 months to 8 years.
• Body dissatisfaction assessed at age 8 years using a pictorial instrument comparing current and desired body sizes.
• Participants included 205 girls and 230 boys in a Finnish prospective trial.

Main Results:

• Children, particularly girls, desiring a thinner body at age 8 showed a faster increase in relative weight between ages 3 and 8.
• Significant differences in weight change trends were observed among children with varying body size satisfaction (P = .002 for girls; P = .02 for boys).
• These findings suggest a link between weight change trajectory and body dissatisfaction.

Conclusions:

• Body dissatisfaction emerging in prepuberty may be a reflection of weight changes over preceding years.
• Early weight gain patterns could be an indicator for potential body image concerns.
• Further research can explore targeted interventions based on weight trajectory and body dissatisfaction.
