To describe depictions of food, alcohol, and exercise and sport in popular films.
Content analysis of the 10 top-grossing films each year from 1991 to 2000 (N = 100 films).
Coding reliabilities were assessed with Cohen's kappa. Research questions were addressed with basic descriptive statistics. Associations among variables were examined through a cross-tabulation procedure that corrects for the clustering of exercise and food depictions within movies.
Food and drink appeared regularly in the films analyzed, typically as a background element or prop. On average, food appeared on the screen once every 4.2 minutes. The foods shown were most likely to be fats, oils, and sweets; fruits, vegetables, and dairy products were rarely seen. More than 20% of the food items shown were alcoholic beverages, which were nearly 2 times more likely to be ingested as nonalcohol food items. Planned exercise and sports appeared at a rate of about 2 incidents per hour. These activities rarely received explicit evaluation by characters.
Films frequently portray foods and exercise. These depictions have the potential to cultivate beliefs about normative eating and exercise behavior, suggesting a need for public health professionals to encourage the media to offer healthier images.
描述流行电影中食物、酒精以及运动和体育的呈现情况。
对1991年至2000年每年票房最高的10部电影（共100部电影）进行内容分析。
使用科恩kappa系数评估编码信度。通过基本描述性统计解决研究问题。通过交叉制表程序检查变量之间的关联，该程序可校正电影中运动和食物呈现的聚类情况。
在分析的电影中，食物和饮料经常出现，通常作为背景元素或道具。平均而言，食物每4.2分钟在屏幕上出现一次。展示的食物最有可能是脂肪、油类和甜食；水果、蔬菜和乳制品很少见。超过20%的展示食物是酒精饮料，其被摄入的可能性几乎是非酒精食物的2倍。有计划的运动和体育活动出现的频率约为每小时2次。这些活动很少得到角色的明确评价。
电影经常描绘食物和运动。这些呈现有可能塑造关于正常饮食和运动行为的观念，这表明公共卫生专业人员需要鼓励媒体提供更健康的形象。
