1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundExposure of children and adolescents to unhealthy food through marketing and advertising on television (TV) is associated with increased consumption of unhealthy foods and subsequently, overweight/obesity and diet-related non-communicable diseases (NCDs). This study assessed the nature, frequency, and exposure of children to food and beverage advertisements on TV and the perspectives of children/adolescents and parents on food marketing on TV.

methodsMixed methods, nationally representative study, guided by the International Network for Food and Obesity/NCDs Research, Monitoring and Action Support (INFORMAS) protocol for monitoring food promotion. This entailed simultaneous recording of the three most popular national TV channels in Kenya for eight randomly selected days, 18 h/day, over a 3-month period in 2021-2022. The NOVA classification was used to categorize food based on level of processing. Differences in advertisements by food groups, recording days (weekday/weekend) and seasons (holiday/non-holiday) were assessed. Focus group discussions (n = 14) and in-depth interviews (n = 29) were conducted with school children/adolescents (~ 9-18 years) and parents respectively in three counties, to explore their experiences and perspectives of food advertisements. Data were coded in NVIVO and analyzed thematically.

resultsOf the 3700 advertisements recorded, about a third (36%, n = 1316) comprised of food and beverages; 94.7% (n = 1213) were ultra-processed foods (UPFs), with a mean rate of 2.8 ads/channel per hour, the majority (95.9%, n = 557) of which were broadcast during peak hours. Some of the children interviewed vividly remembered some of the advertised food brands, mainly those related to UPFs. Most parents acknowledged that their children paid attention to food advertisements and sometimes requested and expressed preference for the advertised foods or brands. Parents generally considered food advertising to be safe, with no concerns about unhealthy food exposure to children.

conclusionsExposure of Kenyan children and adolescents to unhealthy foods through advertisements on national TV is higher than healthier food options. These advertisements enhance recognition and recall of the food brands, while parental concern about unhealthy food advertising is limited. Policies restricting advertising of unhealthy foods accompanied by nutrition education are urgently needed to limit unhealthy food exposure and consumption by children and adolescents, to address the increasing burden of overweight/obesity and NCDs.
