To examine children's exposure to food and beverage advertising across a year of Colombian television based on whether products exceed Pan-American Health Organization (PAHO)-defined nutrient thresholds.
Nutritional information was obtained for all foods and beverages advertised and used to categorise each product according to the product category (e.g. beverage, snack food) and nutritional quality based on the PAHO model for identifying products in excess of free sugars, Na or saturated fat or containing non-caloric sweeteners or trans-fat. Television audience ratings data were used to derive the average child audience (unique child viewers) per ad and the number of times ads were seen by children in a single week (weekly impressions) based on product category and nutritional quality.
All food and beverage ads on cable and over-the-air TV in Colombia in 2017.
N/A.
Of all instances of TV ads, 89·3 % were of unhealthy products. A larger proportion of male and female children, as well as children from low (88·01 %), mid (89·10 %) and high (89·10 %) socio-economic status, are exposed to advertising of unhealthy products, but no significant difference was found between these proportions.
The majority of foods and beverages advertised to Colombian children are unhealthy. These findings highlight a need to implement statutory measures to reduce children's exposure to unhealthy food advertising in Colombia, as obesity and overweight have been increasing among school-age children in Colombia, and exposure to television advertising of unhealthy foods is a known contributor to children's food intake and obesity.
根据产品是否超过泛美卫生组织(PAHO)定义的营养阈值,调查哥伦比亚儿童在一整年电视节目中接触食品和饮料广告的情况。
获取所有广告食品和饮料的营养信息,并根据产品类别(如饮料、休闲食品)以及基于PAHO模型的营养质量对每个产品进行分类,该模型用于识别游离糖、钠或饱和脂肪含量超标或含有非热量甜味剂或反式脂肪的产品。电视观众收视率数据用于根据产品类别和营养质量得出每个广告的平均儿童观众数量(独特儿童观众)以及儿童在一周内观看广告的次数(每周曝光量)。
2017年哥伦比亚有线电视和无线电视上的所有食品和饮料广告。
无。
在所有电视广告中,89.3%是不健康产品的广告。较大比例的男童和女童,以及来自低(88.01%)、中(89.10%)和高(89.10%)社会经济地位的儿童接触到不健康产品的广告,但这些比例之间未发现显著差异。
向哥伦比亚儿童做广告的大多数食品和饮料都不健康。这些发现凸显了在哥伦比亚实施法定措施以减少儿童接触不健康食品广告的必要性,因为哥伦比亚学龄儿童的肥胖和超重问题一直在增加,而接触不健康食品的电视广告是导致儿童食物摄入量和肥胖的一个已知因素。
