Snacking is a complex behavior that may be influenced by entertainment media. Research suggests that snacking and unhealthy foods are commonly shown in programming that targets young audiences, but shows selected for study have been limited. We conducted a content analysis on shows that were named as favorites by adolescents to characterize portrayals of snacking on popular television.
A diverse sample of 2,130 adolescents (mean age, 14.3 y) listed 3 favorite television shows in a 2010 school-based survey. Three episodes each of the 25 most popular shows were coded for food-related content, including healthfulness, portion size, screen time use, setting, and social context. We also analyzed the characteristics of characters involved in eating incidents, the show type, and the show rating. We used χ(2) tests, binomial tests, and multilevel regression models to compare incidence of snacks versus meals, the characteristics of those involved, and snacking across show characteristics.
Almost half of food incidents on television shows were snacks. Snacks were significantly more likely than meals to be "mostly unhealthy" (69.3% vs 22.6%, P < .001) and were more likely to include screen time use (25.0% of snacking incidents vs 4.0% of meals, P < .001). Young characters and those coded as being of low socioeconomic status or overweight were overrepresented in snacking incidents. Sitcoms and shows rated for a youth audience were significantly more likely to portray snacking than were shows for adult audiences.
Media awareness and literacy programs should include foods and snacking behaviors among the issues they address. More healthful portrayals of food and dietary intake in entertainment shows' content would create a healthier media environment for youth.
吃零食是一种复杂的行为,可能会受到娱乐媒体的影响。研究表明,针对年轻观众的节目中普遍出现吃零食和不健康食品的画面,但此前用于研究的节目有限。我们对青少年列为最喜爱的节目进行了内容分析,以描述流行电视节目中吃零食的画面特征。
在2010年的一项校内调查中,2130名不同背景的青少年(平均年龄14.3岁)列出了他们最喜欢的3部电视节目。对25部最受欢迎节目中的每部各3集进行与食物相关内容的编码,包括健康程度、份量大小、屏幕时间使用情况、场景和社会背景。我们还分析了饮食情节中角色的特征、节目类型和节目评级。我们使用卡方检验、二项式检验和多水平回归模型来比较零食与正餐的出现频率、相关人物的特征以及不同节目特征下的吃零食情况。
电视节目中近一半的饮食情节是吃零食。零食比正餐更有可能“大多不健康”(69.3%对22.6%,P < .001),并且更有可能涉及屏幕时间使用(25.0%的零食情节对4.0%的正餐情节,P < .001)。年轻角色以及被编码为社会经济地位低或超重的角色在吃零食情节中占比过高。情景喜剧和面向青少年观众评级的节目比面向成人观众的节目更有可能描绘吃零食的场景。
媒体意识和素养项目应将食品和吃零食行为纳入其涉及的问题之中。在娱乐节目内容中更健康地描绘食物和饮食摄入情况,将为青少年创造一个更健康的媒体环境。
