Descriptive analysis of eating regulation in obese and nonobese children
Insights
This study reduced children's eating bite rate, leading to less food consumed. Obese and nonobese children showed distinct eating behaviors, particularly with breadstuffs and milk.
Area of Science:
- Behavioral Psychology
- Pediatric Nutrition
- Childhood Obesity Research
Background:
- Understanding children's eating behaviors is crucial for addressing pediatric obesity.
- Identifying factors influencing food intake can inform dietary interventions.
- Previous research suggests behavioral strategies can modify eating habits.
Purpose of the Study:
- To investigate the impact of a behavioral intervention on children's bite rate and food consumption.
- To examine behavioral covariations during mealtimes, including sip rate and concurrent activities.
- To explore differences in eating behaviors between obese and nonobese children.
Main Methods:
- Observation of bite rate, sip rate, and concurrent activities in six 7-year-old children (3 obese, 3 nonobese) over six months.
- Implementation of a behavioral procedure to decrease bite rate (placing utensils down between bites) using a multiple-baseline across-subjects design.
- Analysis of food preferences across six food categories and correlations between different behavioral responses.
Main Results:
- The intervention successfully controlled bite rate across all subjects, resulting in a significant reduction in the amount of food consumed.
- Correlations indicated that sip rate and concurrent activities were at least partially independent of bite rate.
- Obese and nonobese children exhibited notable differences in eating behaviors related to breadstuffs and milk consumption.
Conclusions:
- A behavioral intervention targeting bite rate is effective in reducing food intake in children.
- Eating behaviors like sip rate and concurrent activities may not be directly linked to bite rate.
- Distinct eating patterns exist between obese and nonobese children, particularly concerning specific food types.
Abstract:
Bite rate, sip rate, and concurrent activities of six 7-yr-old children, three obese and three nonobese, were observed at lunchtime over a six-month period. A procedure for decreasing bite rate, putting eating utensils down between bites, was implemented in a multiple-baseline across-subjects design. Sip rates and concurrent activities were observed to assess behavioral covariations. In addition, bite rate and amount of food completed were computed over six food categories to analyze food preferences. Results indicated the control of bite rate acorss all subjects, with a significant reduction in amount of food consumed. Correlations between the response classes indicated they were at least partially independent. Differences in eating behavior of obese and nonobese subjects were observed for breadstuffs and milk drinking.
