Summary
Objective
Parent's use of restrictive feeding practices is associated with child weight. Similarly, the literature shows that children's eating behaviours are also associated with child weight. Given this interrelationship between children's eating behaviours, restrictive feeding practices and child weight, examination of possible mediator relationships is warranted. This study aimed to examine the relationships between overt restriction and covert restriction with child body mass index
z
‐scores (BMIz) and determine if children's eating behaviours (satiety responsiveness and food responsiveness) act as mediators.
Method
Parents of Australian children (
n
= 977) 2.0–5.0 years of age (49.4% male) provided data in an online survey on child eating behaviours, parent's restrictive feeding practices and child anthropometrics (modified
z
‐scores were created to screen for biologically implausible values). Correlation analysis was used to determine variables to include in mediation models. Hayes' PROCESS macros in
spss
was used to examine mediation, controlling for covariates of child BMIz.
Results
Overt restriction was the only parent feeding practice related to child BMIz (
B
= 0.132,
P
= 0.04). Mediation analysis showed that the indirect effect of overt restriction on child BMIz (controlling for child age, gender, parent BMI and income) became non‐significant when controlling for food responsiveness, thus suggesting full mediation, explaining 5.75% of the relation.
Conclusion
Overt restriction and covert restriction have distinctly different relationships with children's eating behaviours. Food responsiveness appears an important intermediary in the relationship between overt restriction and child BMIz.
