Insights
Most parents underestimate their children's weight status, failing to recognize overweight or obesity. This underestimation may hinder parental motivation for weight management interventions.
Area of Science:
- Pediatric health
- Obesity research
- Public health
Background:
- Childhood obesity is a growing public health concern.
- Accurate perception of weight status by parents is crucial for timely intervention.
- Studies indicate a potential disconnect between actual and perceived child weight status.
Purpose of the Study:
- To assess parents' accuracy in identifying their children's weight categories.
- To compare parental perception with measured weight status using standardized criteria.
- To explore factors influencing misclassification of children's weight.
Main Methods:
- Cross-sectional study involving 5- and 11-year-old children and their parents.
- Objective measurements of height, weight, and waist circumference to calculate Body Mass Index (BMI).
- Parental questionnaires on perceived child weight status; analysis using Cohen's Kappa for agreement.
Main Results:
- Prevalence of overweight/obesity was 17.4% (5-year-olds) and 21.6% (11-year-olds).
- A majority of parents underestimated their children's weight, misclassifying overweight/obese children as normal weight.
- Waist circumference measurements did not improve parental classification accuracy.
Conclusions:
- Most parents fail to recognize overweight or obesity in their young children.
- Underestimation of childhood overweight may reduce parental motivation for weight control.
- Interventions are needed to improve parental awareness of children's weight status.
Aim:
The aim of this study was to evaluate parents' ability to perceive the weight status of their children.
Methods:
This cross-sectional study was performed on 5 (n = 310) and 11-year-old (n = 296) children. The height, weight and waist circumference were measured. Body mass index (BMI, kg/m²) was calculated. The International Obesity Task Force criteria and the British cut-off points were used to classify BMI and waist circumference. Parents filled out a questionnaire concerning their perception of the weight class of their child. The parents and the 11-year-old children estimated their own weight class. For analysis, the measured and perceived weight classes were divided into two categories; normal weight (including underweight) and overweight or obese. To measure the agreement cross-tabulation with Cohen's Kappa was used. Explanatory variables associated with misclassification of overweight children as normal weight were examined by logistic regression modelling.
Results:
The prevalence of overweight (including obese) was 17.4% and 21.6% in 5- and 11-year-old children in this study. Only a few parents misclassified their normal weight children as overweight. By contrast, a majority of parents to the 5-year-old children and about half of the parents to the 11-year-old children misclassified them as normal weight. Using waist circumference for body size classification did not improve parents' performance. Mothers performed best when estimating own weight class.
Conclusion:
A majority of parents fail to recognize overweight or obesity in their 5- and 11-year-old children. The underestimation of overweight may impair the motivation of the parents to adopt weight control.
