We examined the frequency of adolescents' use of electronic media (ie, television/movie watching, text messaging, talking on the telephone, listening to music with headphones, and playing with hand-held games) at family meals and examined associations with demographic characteristics, rules about media use, family characteristics, and the types of foods served at meals using an observational, cross-sectional design. Data were drawn from two coordinated, population-based studies of adolescents (Project Eating Among Teens 2010) and their parents (Project Families and Eating Among Teens). Surveys were completed during 2009-2010. Frequent television/movie watching during family meals by youth was reported by 25.5% of parents. Multivariate logistic regression analyses indicated significantly higher odds of mealtime media use (P<0.05) for girls and older teens. In addition, higher odds of mealtime media use (P<0.05) were also seen among those whose parents had low education levels or were black or Asian; having parental rules about media use significantly reduced these odds. Frequent mealtime media use was significantly associated with lower scores on family communication (P<0.05) and scores indicating less importance placed on mealtimes (P<0.001). Furthermore, frequent mealtime media use was associated with lower odds of serving green salad, fruit, vegetables, 100% juice, and milk at meals, whereas higher odds were seen for serving sugar-sweetened beverages (P<0.05). The ubiquitous use of mealtime media by adolescents and differences by sex, race/ethnicity, age, and parental rules suggest that supporting parents in their efforts to initiate and follow-through on setting mealtime media use rules may be an important public health strategy.
我们考察了青少年在家庭聚餐时使用电子媒体(例如,看电视/电影、发短信、打电话、戴耳机听音乐以及玩手持游戏)的频率,并使用观察性、横断面设计,考察了与人口统计学特征、媒体使用规则、家庭特征以及用餐时供应的食物类型的关联。数据来自于对青少年(青少年饮食研究 2010 项目)及其父母(家庭和青少年饮食研究)的两项协调、基于人群的研究。调查于 2009-2010 年进行。25.5%的家长报告青少年在家庭聚餐时常看电视/电影。多变量逻辑回归分析表明,女性和年龄较大的青少年在进餐时使用媒体的几率更高(P<0.05)。此外,父母教育程度较低或为黑人和亚裔的青少年在进餐时使用媒体的几率更高(P<0.05);父母制定媒体使用规则可显著降低这种几率。频繁在进餐时使用媒体与家庭沟通评分较低(P<0.05)和表示对进餐时间重视程度较低的评分呈显著负相关(P<0.001)。此外,频繁在进餐时使用媒体与供应绿叶沙拉、水果、蔬菜、100%果汁和牛奶的几率较低有关,而供应含糖饮料的几率较高(P<0.05)。青少年在进餐时普遍使用媒体,且在性别、种族/民族、年龄和父母规则方面存在差异,这表明支持父母努力制定和执行进餐时使用媒体的规则可能是一项重要的公共卫生策略。
