Interventions to Counter Health Misinformation Among Older People: Protocol for a Scoping Review

Misinformation and disinformation in health are significant issues because they undermine trust in public health authorities, scientists, and governments [1-4].

Conversely, disinformation involves the intentional spread of inaccurate information with the aim of misleading or causing harm, while misinformation, although still incorrect, is shared without malicious intent [6].

These falsehoods can take various forms, such as promoting untested remedies or treatments, voicing inaccurate health claims, and propagating conspiracy theories about illnesses, climate change, and vaccines [6].

Based on our content analysis, most videos did not explicitly disclose specific ingredients in the breast enhancement products they promoted.
