Online food delivery (OFD) platforms guarantee access to food during the coronavirus disease 2019 (COVID-19) pandemic when commercial food establishments are closed and access to food retail is controlled. The present study aimed to describe the advertisements published in an OFD platform in Brazilian capitals, during the 13th and 14th weeks of the pandemic. Data collection occurred on 1 d of the week and 1 d of the weekend and during lunch and dinner time. A random sample of 25 % of the advertisements (n 1754) published in this period was classified in accordance with the presence of food groups and to the use of marketing strategies. Sandwiches, ultra-processed beverages, traditional meals or pasta were the most common food groups shown in the advertisements. Free delivery prevailed in advertisements of ice cream, candies or salty packages snacks and pizza (P < 0·01). Combos were more frequently shown in the advertising of natural juices or smoothies, ultra-processed beverages, sandwiches and pizzas (P < 0·01). Messages about healthiness were more seen among natural juices or smoothies, vegetables and traditional meals and pasta advertisements (P < 0·01) and less seen in sandwiches (P = 0·02) and pizza advertisements (P < 0·01). Economy messages were rare in advertisements of traditional meals or pasta (P < 0·01) and more common in ultra-processed beverages (P = 0·03) and ice cream, candies or salty packages snacks (P < 0·01) advertisements. The OFD platform promoted unhealthy eating during the COVID-19 pandemic in Brazil due to the expressive presence of unhealthy foods advertising.

在线食品配送 (OFD) 平台可保证在 2019 年冠状病毒病 (COVID-19) 大流行期间商业食品场所关闭且食品零售渠道受到控制时获得食品。本研究旨在描述大流行第 13 周和第 14 周期间巴西首都 OFD 平台上发布的广告。数据收集发生在一周的 1 天和周末的 1 天以及午餐和晚餐时间。根据食品类别的存在和营销策略的使用，对这一时期发布的广告（n 1754）中的 25% 进行了随机抽样。三明治、超加工饮料、传统餐食或面食是广告中最常见的食物类别。免费送货在冰淇淋、糖果或咸味包装零食和披萨的广告中盛行(P < 0·01)。组合更频繁地出现在天然果汁或冰沙、超加工饮料、三明治和披萨的广告中（P < 0·01）。有关健康的信息更多地出现在天然果汁或冰沙、蔬菜和传统膳食以及面食广告中 (P < 0·01)，而较少出现在三明治 (P = 0·02) 和披萨广告 (P < 0·01) 中。经济信息在传统餐食或面食的广告中很少见 (P < 0·01)，而在超加工饮料 (P = 0·03) 和冰淇淋、糖果或咸味包装零食 (P < 0·01) 中更常见）广告。由于不健康食品广告的表现力，OFD 平台在巴西 COVID-19 大流行期间宣传了不健康饮食。
