[Parent-child parallel nutritional status assessment using silhouette rating scales]

Area of Science:

• Pediatric Nutrition
• Anthropometry
• Genetics of Obesity

Context:

• Assessing nutritional status in school-aged children is crucial for early intervention.
• Understanding the genetic component of obesity requires reliable assessment tools.
• Silhouette rating scales offer a visual method for evaluating body image and nutritional status.

Purpose:

• To validate the use of silhouette rating scales for assessing nutritional status in 12-14-year-old children.
• To explore the relationship between children's body mass index (BMI) and their perception of their own and their parents' body size.
• To investigate potential genetic influences on obesity through parallel assessment of children and parents.

Summary:

• A study involving 290 schoolchildren (ages 12-14) used silhouette scales to assess nutritional status alongside BMI measurements.
• Significant differences in BMI were observed between children of parents rated as 'normal' versus 'problematic'.
• Children with normal BMI selected lower silhouette numbers, while those with problematic BMI chose higher numbers, indicating perceived body size differences. Gender and BMI status significantly influenced assessments, with girls perceiving larger body sizes for mothers and boys perceiving larger father sizes within normal BMI categories.

Impact:

• Silhouette rating scales demonstrate reliability in the parallel assessment of children's and parents' nutritional status.
• Findings suggest silhouette scales can be a valuable tool in identifying potential genetic predispositions to obesity.
• Further research incorporating parental height and body mass data could enhance understanding of obesity genetics.
