Coparenting quality and food parenting practices have been shown to have a strong influence on child outcomes. However, little is known about whether coparenting quality may influence food parenting practices. This study aimed to investigate how coparenting quality is associated with both mothers' and fathers' food parenting practices. A cross-sectional analysis was conducted of 58 mothers and 40 fathers enrolled in the Guelph Family Health Study. The Coparenting Relationship Scale and the Comprehensive Feeding Practices Questionnaire were used to measure coparenting and food parenting practices, respectively. Linear regressions using generalized estimating equations were used to examine associations between coparenting quality and food parenting practices in mothers and fathers. Among mothers, higher coparenting quality was associated with lower use of food for emotional regulation, restriction of food for health, and child control of food intake and with higher encouragement of a balanced and varied diet, provision of a healthy home environment, and modeling of healthy eating behaviors. Among fathers, higher coparenting quality was associated with lower pressure to eat and with higher encouragement of a balanced and varied diet and provision of a healthy home environment. Coparenting quality is associated with food parenting practices among both mothers and fathers. Interventions aiming to improve food parenting practices should include fathers and should consider targeting parents' coparenting relationship.
