目的：研究家长报告家庭食物供应和家长水果，蔬菜和乳制品的摄入量与青少年摄入相同食物的纵向关联。本研究扩展了有限的纵向研究，探讨父母和家庭食物供应在青少年膳食摄入中的作用。设计：纵向研究。EAT-II项目从1999年（时间1）至2004年（时间2）对不同种族和社会经济背景的青少年进行了抽样调查。除了EAT项目调查外，青少年在两个时间段内完成了青少年食物频率问卷，青少年的父母在时间1完成了电话调查。一般线性模型被用来检查父母摄入量和家庭可用性和青少年摄入量之间的关系，调整时间1青少年摄入量。分别对高中和年轻成人队列以及合并队列中的男性和女性进行了关联性检查。主题/设置：样本包括509对父母/监护人和青少年。晚餐供应的蔬菜显著预测了男性青少年的蔬菜摄入量5年随访时，女性（P = 0.009）、高中生（P = 0.033）和年轻人（P = 0.05）。在年轻人中，晚餐时提供牛奶可以预测乳制品摄入量（P = 0.002）。时间I父母摄入量显着预测摄入量的年轻成年人的水果（P = 0.044），蔬菜（P = 0.041）和乳制品（P = 0.008）。父母的摄入量预测摄入量的乳制品的女性（P = 0.02）。结论：研究结果表明，为青少年的父母提供的知识和技能，以提高家庭食品环境，改善自己的饮食行为的重要性。
Objective: To examine longitudinal associations of parental report of household food availability and parent intakes of fruits, vegetables and dairy foods with adolescent intakes of the same foods. This study expands upon the limited research of longitudinal studies examining the role of parents and household food availability in adolescent dietary intakes.Design: Longitudinal study. Project EAT-II followed an ethnically and socio-economically diverse sample of adolescents from 1999 (time 1) to 2004 (time 2). In addition to the Project EAT survey, adolescents completed the Youth Adolescent Food-Frequency Questionnaire in both time periods, and parents of adolescents completed a telephone survey at time 1. General linear modelling was used to examine the relationship between parent intake and home availability and adolescent intake, adjusting for time 1 adolescent intakes. Associations were examined separately for the high school and young adult cohorts and separately for males and females in combined cohorts.Subjects/setting: The sample included 509 pairs of parents/guardians and adolescents.Results: Vegetables served at dinner significantly predicted adolescent intakes of vegetables for males (P = 0.037), females (P = 0.009), high school (P = 0.033) and young adults (P = 0.05) at 5-year follow-up. Among young adults, serving milk at dinner predicted dairy intake (P = 0.002). Time I parental intakes significantly predicted intakes of young adults for fruit (P = 0.044), vegetables (P = 0.041) and dairy foods (P = 0.008). Parental intake predicted intake of dairy for females (P = 0.02).Conclusions: The findings suggest the importance of providing parents of adolescents with knowledge and skills to enhance the home food environment and improve their own eating behaviours.
