Identifying children's environmental health risks, needs, misconceptions, and opportunities for research translation using social media.

As part of the Advancing Science, Practice, Programming, and Policy in Research Translation for Children's Environmental Health (ASPIRE) center, machine learning, geographic information systems (GIS), and natural language processing to analyze more than 650 million posts related to children's environmental health are being used. Using preliminary analyses as examples, this commentary discusses the potential opportunities, benefits, challenges, and limitations of children's health social media analytics. Social media contains large volumes of contextually rich data that describe children's health risks and needs, characteristics of homes and childcare locations important to environmental exposures, and parent and childcare provider perceptions, awareness of, and misconceptions about children's environmental health. Twenty five million unique conversations mentioning children, with likes, views, and replies from more than 33 million X (formerly Twitter) users were identified. Many of these posts can be linked to traditional environmental and health data. However, social media analytics have several challenges and limitations. Challenges include a need for interdisciplinary collaborations, selectivity and sensitivity of analytical methods, the dynamic, evolving communication methods and platform preferences of social media users, and operational policies. Limitations include data availability, generalizability, and self-report bias. Social media analytics has significant potential to contribute to children's environmental health research and translation.
