The study's objective was to determine patterns of food parenting practices regarding fruit and vegetables (FV) and their associations with demographic characteristics and dietary intake in parents and adolescents (12-17 years). Dyadic survey data from Family Life, Activity, Sun, Health, and Eating, a cross-sectional, Internet-based study, conducted in 2014 were analyzed using latent class analysis. Self-report model covariates included adolescent age and parent and adolescent sex, BMI, FV intake, and FV legitimacy of parental authority (FV-LPA). Based on 1657 parent-adolescent dyads, 5 latent classes were identified representing use of all 6 to use of few FV parenting practices. Parent and adolescent responses agreed in four classes. The high use class was the reference class. Compared with early adolescent dyads, middle adolescent dyads had 58% and 66% lower odds of belonging to moderate and low use classes. Compared with female parent dyads, male parent dyads had over three times greater odds of belonging to low use class. Compared with female adolescent dyads, male adolescent dyads had 44% lower odds of belonging to disagreeing class. The odds of belonging to one of the other four classes were 19%-63% lower for every one cup equivalent increase in parent FV intake. Compared with dyads with high parental or adolescent agreement with FV-LPA, dyads with low agreement had 2.5-7 times the odds of belonging to another class. Distinct patterns of FV parenting practices exist and are associated with parent and adolescent demographic characteristics, dietary intake, and FV-LPA.
本研究旨在确定有关水果和蔬菜（FV）的食物养育实践模式及其与父母和青少年（12-17 岁）人口统计学特征和饮食摄入的关联。使用潜在类别分析对 2014 年进行的基于家庭生活、活动、阳光、健康和饮食的横断面互联网研究的家庭生活、活动、阳光、健康和饮食的对偶调查数据进行了分析。自我报告模型协变量包括青少年年龄以及父母和青少年的性别、BMI、FV 摄入量和父母权威的 FV 合法性（FV-LPA）。基于 1657 对父母-青少年对偶，确定了 5 个潜在类别，代表使用了所有 6 个或很少使用 FV 养育实践。父母和青少年的回答在四个类别中一致。高使用类别为参考类别。与早期青少年对偶相比，中期青少年对偶属于中度和低度使用类别的可能性低 58%和 66%。与女性父母对偶相比，男性父母对偶属于低度使用类别的可能性高出三倍以上。与女性青少年对偶相比，男性青少年对偶属于不同意类别可能性低 44%。与每增加一杯父母 FV 摄入量相当的情况下，属于其他四个类别之一的可能性低 19%-63%。与父母或青少年对 FV-LPA 高度一致的对偶相比，一致性低的对偶属于另一个类别的可能性高 2.5-7 倍。存在不同的 FV 养育实践模式，并且与父母和青少年的人口统计学特征、饮食摄入和 FV-LPA 相关。
