To determine the frequency and content of food-related television (TV) advertisements shown on South African TV.
Four national TV channels were recorded between 15.00 and 21.00 hours (6 h each day, for seven consecutive days, over a 4-week period) to: (i) determine the number of food-related TV advertisements; and (ii) evaluate the content and approach used by advertisers to market their products. The data were viewed by two of the researchers and coded according to time slots, food categories, food products, health claims and presentation.
Of the 1512 recorded TV advertisements, 665 (44 %) were related to food. Of these, 63 % were for food products, 21 % for alcohol, 2 % for multivitamins, 1 % for slimming products and 13 % for supermarket and pharmacy promotions. Nearly 50 % of food advertisements appeared during family viewing time. During this time the most frequent advertisements were for desserts and sweets, fast foods, hot beverages, starchy foods and sweetened drinks. The majority of the alcohol advertisements (ninety-three advertisements, 67 %) fell within the children and family viewing periods and were endorsed by celebrities. Health claims were made in 11 % of the advertisements. The most frequently used benefits claimed were ‘enhances well-being’, ‘improves performance’, ‘boosts energy’, ‘strengthens the immune system’ and ‘is nutritionally balanced’.
The majority of food advertisements shown to both children and adults do not foster good health despite the health claims made. The fact that alcohol advertisements are shown during times when children watch TV needs to be addressed.
确定南非电视上播放的与食品相关的电视(TV)广告的频率和内容。
在 15.00 至 21.00 小时(每天 6 小时,连续 7 天,共 4 周)之间记录四个国家电视频道,以:(i)确定与食品相关的电视广告数量;(ii)评估广告商推销其产品的内容和方法。两位研究人员观看了这些数据,并根据时间段、食品类别、食品产品、健康声明和展示方式进行了编码。
在记录的 1512 个电视广告中,有 665 个(44%)与食品相关。其中,63%是食品产品广告,21%是酒精广告,2%是多种维生素广告,1%是减肥产品广告,13%是超市和药店促销广告。近 50%的食品广告出现在家庭观看时间。在此期间,最常见的广告是甜点和糖果、快餐、热饮、淀粉类食品和加糖饮料。大多数酒精广告(93 个广告,67%)都在儿童和家庭观看时段播出,并由名人代言。广告中声称有 11%的健康声明。声称的最常见的好处是“增强幸福感”、“提高表现”、“增强能量”、“增强免疫系统”和“营养均衡”。
尽管声称有健康声明,但向儿童和成年人展示的大多数食品广告并没有促进健康。在儿童看电视的时间播出酒精广告的事实需要加以解决。
