A large proportion of adolescents eats too many energy-dense snacks, which is detrimental for their current and future health. To understand how to promote healthy dietary behaviors in adolescents, we need to identify factors that affect their snacking. While previous cross-sectional work has shown mother-child similarities in eating behavior, longitudinal studies are lacking. Hence, the first aim of this study was to examine whether maternal snacking predicted changes in adolescents' snacking over time. A second aim was to examine whether adolescents' television viewing magnified the strength of this longitudinal association. Television viewing may increase the motivation to eat the snacks consumed by mothers later on, for example through food advertisement exposure and mindless eating. To address both aims, 2051 adolescents (M baseline = 13.81; 51.5% boys) were asked to report on their snacking and television viewing three times, with intervals of one year. Moreover, a subsample of mothers of adolescents (N = 1080) reported on their snacking at baseline as well. The results indicate that maternal snacking indeed predicts adolescents' snacking over time and that this effect is more pronounced among adolescents who watch a great amount of television. These findings attest to the importance of mothers in forming adolescents' snacking, not only concurrently but also prospectively. Additionally, this study highlights the relevance of assessing other home environmental factors that may influence maternal effects on their children's snacking.
很大一部分青少年吃太多高能量的零食，这对他们现在和未来的健康都不利。为了了解如何促进青少年的健康饮食行为，我们需要确定影响他们吃零食的因素。虽然之前的横断面研究表明，母亲和孩子的饮食行为存在相似性，但缺乏纵向研究。因此，这项研究的第一个目的是检验母亲的零食摄入量是否能预测青少年随时间的变化而改变。第二个目的是检验青少年看电视的习惯是否会放大这种纵向关联的强度。看电视可能会通过食品广告的影响和无意识的进食等方式，增加青少年之后吃母亲吃的零食的动机。为了达到这两个目的，2051 名青少年（M 基线= 13.81；51.5%为男性）被要求在一年的时间内三次报告他们的零食摄入量和看电视习惯。此外，青少年的一部分母亲（N=1080）在基线时也报告了她们的零食摄入量。结果表明，母亲的零食摄入量确实能预测青少年随时间的变化而变化，而且这种影响在看电视较多的青少年中更为明显。这些发现证明了母亲在形成青少年的零食摄入量方面的重要性，不仅是同时，而且是前瞻性的。此外，这项研究还强调了评估其他家庭环境因素的重要性，这些因素可能会影响母亲对孩子零食摄入量的影响。
