This is an experiment in AI-driven contextualization. The material below was produced using SIFT Toolbox, a human-in-the-loop LLM-based contextualization toolbox designed to accelerate fact-checking and sensemaking. Findings should be considered draft findings, lightly checked at best. This check of the report was done as a test to check the robustness and usefulness of the Toolbox.

Context Report: Youth Physical Activity Statistics

Over 70% of children, and 85% of teens, fail to meet the 2024 federal guideline of 60 minutes of daily moderate-to-vigorous physical activity.

This statement is largely accurate regarding childhood physical inactivity rates, with authoritative 2024 data confirming that 72-80% of American children aged 6-17 fail to meet federal guidelines. However, the statement contains multiple serious problems: it misreferences a "2024 federal guideline" when the standard was established in 2018, citation 58 is completely inappropriate (a historical meta-analysis with no US data after 1992 that measures different outcomes), and contains citation formatting errors plus a non-functional website URL. The statement also lacks important context that this represents a persistent rather than worsening crisis, with grades remaining unchanged since systematic tracking began in 2014.
