Relationship between Parental Beverage Knowledge, Intake and Home Availability and Early Adolescent Beverage Intake

Nutrition‐ and health‐related knowledge has been associated with sugar‐sweetened beverage intake among adults. The purpose of this study was to determine whether parent beverage knowledge, role modeling and home availability were related to beverage intake of early adolescents (9‐12 years). Items were constructed to test knowledge of beverage calorie and sugar content, intake recommendations, and label reading and tested with undergraduate nutrition students to adjust level of difficulty. A survey was administered to 194 parents at the Minnesota State Fair to assess usual beverage intake, home beverage availability and beverage knowledge. Early adolescents completed a survey to assess usual beverage intake. The majority of parents were white (92%), had some college/蠅 4 year degree (94%), women (81%) and employed full/part time (82%); mean age and BMI were 42.7 years and 26.2, respectively. Mean child (SD) age was 10.6 (1.1), 49% were boys. Mean parent beverage knowledge score was 6.1/9.0. Mean child and parent sweetened beverage intakes (soft drink plus fruit drink) were 3.8 and 4.8 oz/day, respectively. Parent and child sweetened beverage intakes were negatively correlated with parent‐reported home availability of soft drinks (r=‐.318, p<0.0001) and fruit drinks (r=‐0.395, p <0.0001). Child sweetened beverage intake was positively correlated with parent sweetened beverage intake (r=0.178, p=0.013). Parent beverage knowledge was not related to parent or child sweetened beverage intakes or home availability of soft drinks/fruit drinks. Results indicate that in a well‐educated sample, home availability and role modeling may influence child sweetened beverage intake, while parent beverage knowledge may not be a strategic target for educational intervention.
