Insights
Preschoolers
Area of Science:
- Child Development
- Pediatric Nutrition
- Physical Activity in Early Childhood
Background:
- Children often imitate behaviors of similar individuals, making peers potential role models.
- Peer influence is significant in shaping children's habits within social environments like childcare centers.
Purpose of the Study:
- To investigate if peer behaviors predict changes in preschoolers' dietary intake and physical activity.
- To understand the longitudinal impact of peer influence on young children's health behaviors over nine months.
Main Methods:
- A longitudinal study involving 238 preschoolers (aged 3-5) across 23 childcare centers.
- Dietary intake assessed via weighed plate waste and digital photography; physical activity measured using accelerometers over five days.
- Multilevel linear regressions analyzed the influence of peer behaviors on individual changes in diet and activity.
Main Results:
- Preschoolers with dietary intake or physical activity levels most different from their peers showed the greatest change towards similarity.
- Observed changes indicate a convergence towards peer norms in both eating and activity behaviors over the nine-month period.
Conclusions:
- Peer behaviors significantly influence preschoolers' dietary intake and physical activity in childcare settings.
- Children's peer groups can be leveraged to promote healthy eating and physical activity through positive role modeling interventions.
Abstract:
Preschoolers observe and imitate the behaviors of those who are similar to them. Therefore, peers may be role models for preschoolers' dietary intake and physical activity in childcare centers. This study examined whether peers' behaviors predict change in preschoolers' dietary intake and physical activity in childcare centers over 9months. A total of 238 preschoolers (3 to 5years old) from 23 childcare centers in two Canadian provinces provided data at the beginning (October 2013 and 2014) and the end (June 2014 and 2015) of a 9-month period for this longitudinal study. Dietary intake was collected at lunch using weighed plate waste and digital photography on two consecutive weekdays. Physical activity was assessed using accelerometers over five days. Multilevel linear regressions were used to estimate the influence of peers' behaviors on preschoolers' change in dietary intake and physical activity over 9months. Results showed that preschoolers whose dietary intake or physical activity level deviated the most from those of their peers at the beginning of the year demonstrated greater change in their intakes and activity levels over 9months, which enabled them to become more similar to their peers (all β 95% CI ranged from -0.835 to -0.074). This study suggests that preschoolers' dietary intake and physical activity may be influenced by the behaviors of their peers in childcare centers. Since peers could play an important role in promoting healthy eating behaviors and physical activity in childcare centers, future studies should test interventions based on positive role modeling by children.
