BACKGROUND Adolescents are among the highest consumers of sugar-sweetened beverages (SSBs) in the United States. More research is needed to understand the relationship of multiple levels of influence on adolescent SSB intake across the socioecological model in a nationally representative sample. OBJECTIVE This secondary analysis of cross-sectional data aims to explain variance in adolescent SSB intake by exploring the associations of adolescent demographic (ie, age, race/ethnicity, and parent socioeconomic status), intrapersonal (ie, behavioral intention, self-efficacy, and media perception), interpersonal (ie, social norms and perceived parenting practices), and home availability variables. DESIGN This study included 1,560 adolescents who participated in the 2014 National Cancer Institute-sponsored cross-sectional Family, Life, Activity, Sun, Health, and Eating study. Descriptive statistics, analyses of variance, and stepwise multiple linear regression models were used to explore factors associated with SSB intake. In the stepwise regression, a 4-step model was analyzed with each subsequent step adding variables from different socioecological model levels. RESULTS The final step that included 14 variables individually associated with SSB intake significantly predicted 16.5% of the variance in SSB intake. Four variables were associated with higher SSB intake in the final step when controlling for all other variables: male sex (β=.066), non-Hispanic black vs non-Hispanic white (β=.123), adolescent's report of having parents allow them to have SSBs on a bad day (β=.150), and home SSB availability (β=.263). Race/ethnicity other than Hispanic and/or non-Hispanic black vs non-Hispanic white was associated with lower intake (β= -.092). CONCLUSIONS When considering potential targets for multilevel behavioral interventions aimed at reducing adolescent SSB intake, emphasis on reducing SSB availability at home may be especially important. Furthermore, although adolescence is a period of increasing independence, parent influence on adolescent's health behaviors may also be a key intervention target. Home and parental SSB factors may be more important than targeting intrapersonal factors and social norms among adolescents.

使用社会生态学方法确定与青少年含糖饮料摄入量相关的因素

背景青少年是美国含糖饮料（SSB）的最高消费者之一。需要更多的研究来了解在具有全国代表性的样本中跨社会生态模型对青少年 SSB 摄入的多层次影响的关系。目的 横断面数据的二次分析旨在通过探索青少年人口统计（即年龄、种族/民族和父母社会经济地位）、内在因素（即行为意图、自我效能感、和媒体认知）、人际关系（即社会规范和感知的育儿实践）和家庭可用性变量。设计 本研究包括 1,560 名青少年，他们参加了 2014 年国家癌症研究所赞助的横断面家庭、生活、活动、太阳、健康和饮食研究。描述性统计、方差分析和逐步多元线性回归模型用于探索与 SSB 摄入相关的因素。在逐步回归中，分析了一个 4 步模型，随后的每个步骤都添加了来自不同社会生态模型级别的变量。结果 最后一步包括 14 个单独与 SSB 摄入相关的变量，显着预测了 SSB 摄入变化的 16.5%。在控制所有其他变量时，有四个变量与最后一步中较高的 SSB 摄入量相关：男性 (β=.066)、非西班牙裔黑人与非西班牙裔白人 (β=.123)、青少年关于父母允许的报告他们在糟糕的一天拥有 SSB (β=.150)，以及家庭 SSB 可用性 (β=.263)。西班牙裔和/或非西班牙裔黑人与非西班牙裔白人以外的种族/民族与较低的摄入量有关 (β= -.092)。结论 在考虑旨在减少青少年 SSB 摄入量的多层次行为干预的潜在目标时，强调减少家庭中 SSB 的可用性可能尤为重要。此外，虽然青春期是一个独立性不断增强的时期，但父母对青少年健康行为的影响也可能是一个关键的干预目标。家庭和父母的 SSB 因素可能比针对青少年的内在因素和社会规范更重要。强调减少家里的 SSB 可用性可能尤为重要。此外，虽然青春期是一个独立性不断增强的时期，但父母对青少年健康行为的影响也可能是一个关键的干预目标。家庭和父母的 SSB 因素可能比针对青少年的内在因素和社会规范更重要。强调减少家里的 SSB 可用性可能尤为重要。此外，虽然青春期是一个独立性不断增强的时期，但父母对青少年健康行为的影响也可能是一个关键的干预目标。家庭和父母的 SSB 因素可能比针对青少年的内在因素和社会规范更重要。
