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

introductionIn the U.S., there is no consensus of how to define junk food. Strict regulations on what constitutes junk food denoted by front-of-package labels can serve as the basis for statutory actions. Chile was the first country to adopt this approach, and several countries have followed suit. This study examined the proportion of calories and nutrients of concern consumed by U.S. children and adolescents defined as junk food using the Chilean label criteria and the changes between 2003 and 2016.

methodsData were obtained from 4 nationally representative food intake surveys in 13,016 U.S. children and adolescents: National Health and Nutrition Examination Survey 2003-2004, 2005-2006, 2013-2014, and 2015-2016, with analysis performed in 2019. Nutritional content of each consumed food was compared with nutrient thresholds from the Chilean regulation for energy, saturated fat, total sugars, and sodium per 100 g.

resultsBetween 2003 and 2016, there was a 10 percentage point decrease (71.1%-61.3%, p<0.01) in the proportion of foods consumed that were classified as junk food. A significant decrease was seen in mean intake of calories (1,610-1,367 kcal/day, p<0.01), total sugar (88.8-64.2 g/day, p<0.01), saturated fat (22.6-20.5 g/day, p<0.01), and sodium (2,306-2,044 mg/day, p<0.01).

conclusionsAlthough junk food intake has decreased since 2003-2006, diets of U.S. children and adolescents remain dominated by less-healthy foods. These results can help guide policy regulations regarding foods and beverages accessible in schools and marketed to children, adolescents, and their caregivers.
