OBJECTIVE To analyze the association of television food advertisements with eating habits in Brazilian adolescents. METHODS The sample was composed of 1,011 adolescents, aged from 10-17 years. The influence of television food advertisements on eating habits, as well as food consumption and socioeconomic variables were assessed through questionnaires. A binary logistic regression was performed to assess the magnitude of the associations, adjusted for gender, age, socioeconomic status, and parental schooling. RESULTS Of the sample, 83.3% (n = 843) reported food consumption while watching TV. Adolescents who do not consume food while watching TV had a higher weekly consumption of fruits (3.98, SD = 2.0 versus 3.39, SD = 2.1) and vegetables (4.1, SD = 2.2 versus 3.4, SD = 2.3). Adolescents that consume food while watching TV had higher weekly consumption of fried foods (3.1, SD = 2.0 versus 2.3, SD = 1.7), sweets (4.1, SD = 2.1 versus 3.3, SD = 2.1), soft drinks (3.2, SD = 2.1 versus 2.2, SD = 1.9), and snacks (2.3, SD = 2.0 versus 1.6, SD = 1.7). For 73,8% of the sample, food advertisements induce product consumerism, most commonly sweets and fast foods. Buying or asking to buy food after seeing it on the television was associated with fried foods (OR = 1.36, 95%CI = 1.03- 1.79), sweets (OR = 1.69, 95%CI = 1.30-2.18), and snacks (OR = 1.57, 95%CI = 1.12-2.22). CONCLUSION Food advertisements were associated with greater consumption of fried foods, sweets, and snacks in adolescents, even after adjusting for confounding factors.
分析巴西青少年的电视食品广告与饮食习惯之间的关联。
该样本由 1011 名年龄在 10-17 岁的青少年组成。通过问卷调查评估电视食品广告对饮食习惯、食物消费和社会经济变量的影响。采用二元逻辑回归评估关联程度，并调整性别、年龄、社会经济地位和父母教育程度等因素。
在该样本中，83.3%（n=843）报告称在看电视时会进食。不边看电视边进食的青少年每周水果摄入量更高（3.98，SD=2.0 与 3.39，SD=2.1）和蔬菜摄入量（4.1，SD=2.2 与 3.4，SD=2.3）。边看电视边进食的青少年每周摄入更多的油炸食品（3.1，SD=2.0 与 2.3，SD=1.7）、甜食（4.1，SD=2.1 与 3.3，SD=2.1）、软饮料（3.2，SD=2.1 与 2.2，SD=1.9）和零食（2.3，SD=2.0 与 1.6，SD=1.7）。在样本中，73.8%的青少年认为食品广告会诱导产品消费主义，最常见的是甜食和快餐。看到电视上的食品广告后购买或要求购买该食品与油炸食品（OR=1.36，95%CI=1.03-1.79）、甜食（OR=1.69，95%CI=1.30-2.18）和零食（OR=1.57，95%CI=1.12-2.22）相关。
即使在调整了混杂因素后，食品广告仍与青少年食用更多的油炸食品、甜食和零食有关。
