Insights
Parental presence significantly alters eating behavior in obese children, who eat faster with larger bites when mothers are present. This suggests a learned component to childhood obesity, impacting family-based interventions.
Area of Science:
- Pediatric Nutrition
- Behavioral Science
- Childhood Obesity Research
Background:
- Childhood obesity is a growing public health concern.
- Understanding factors influencing eating behavior is crucial for intervention.
- Parental influence on child eating habits requires further investigation.
Purpose of the Study:
- To investigate the influence of parental presence on the eating behavior of obese and normal-weight children.
- To compare the eating styles of children with and without maternal presence.
- To explore the role of learned behaviors in childhood obesity.
Main Methods:
- Controlled repeated measurement design with 80 children (aged 8-12 years).
- Eating behavior was observed in a laboratory setting with the mother either present or absent.
- Eating style was quantified using a universal eating monitor and cumulative eating curves with yogurt as a standardized meal.
Main Results:
- Obese children's eating behavior significantly differed from normal-weight children only when the mother was present.
- Obese children exhibited faster eating rates and larger bite sizes.
- An acceleration in eating rate was observed towards the end of the meal in obese children.
Conclusions:
- The observed eating style in obese children may contribute to increased calorie intake and positive energy balance.
- Findings support a learning model for childhood obesity.
- The results have implications for family-based treatment strategies for childhood obesity.
Objective:
To determine parental influence on obesity, eating behavior of 80 obese and normal weight children (aged 8-12 y) was investigated in the laboratory.
Design:
A controlled repeated measurement design was used. The mother was either present or absent while the child was eating in the laboratory.
Measurements:
The eating style was measured by recording cumulative eating curves with a universal eating monitor, using yoghurt as a standardized experimental meal.
Results:
The eating behavior of obese children differed significantly from normal weight children only when the mother was present in the laboratory. Overweight children ate faster with larger bites and showed an acceleration of their eating rate towards the end of the meal.
Conclusion:
Such an eating style can be hypothesized to explain an increased calorie intake in obese children, promoting a positive energy balance in the long-term. The data support a learning model of obesity in childhood, which also has implications for family treatment.
