When do mothers think their child is overweight?

Area of Science:

• Pediatric Endocrinology
• Public Health Nutrition
• Childhood Obesity Research

Background:

• Parental perception of child weight status is crucial for early intervention in childhood obesity.
• Understanding maternal recognition of overweight and concern for future adiposity is vital for public health strategies.

Purpose of the Study:

• To determine the body mass index (BMI) thresholds at which mothers perceive their children as overweight.
• To identify the BMI level associated with maternal concern about a child's future overweight status.
• To investigate specific adiposity cues that influence mothers' perceptions of their child's weight.

Main Methods:

• Cross-sectional study involving 531 children aged 6-8 years and their mothers.
• Maternal data included perceptions of child adiposity, demographics, and socioeconomic status.
• Child measurements comprised height, weight, waist circumference, skinfolds, bioelectrical impedance, and bone frame.

Main Results:

• Half of mothers classified children as overweight at a body mass index (BMI) of 21.3, an obese range for this age.
• Maternal concern for future overweight emerged at a BMI of 17.1, below the overweight threshold.
• Waist circumference and skinfold thickness were the most significant predictors of maternal perception, overshadowing BMI alone.

Conclusions:

• Health promotion targeting parents should leverage concerns about future overweight rather than current weight status.
• Interventions should focus on visible adiposity cues that mothers respond to, rather than solely on BMI.
• Maternal perception of childhood overweight is influenced by visible body characteristics and maternal own BMI.
