  This study introduces and examines the potential of an AI system to generate
health awareness messages. The topic of folic acid, a vitamin that is critical
during pregnancy, served as a test case. Using prompt engineering, we generated
messages that could be used to raise awareness and compared them to retweeted
human-generated messages via computational and human evaluation methods. The
system was easy to use and prolific, and computational analyses revealed that
the AI-generated messages were on par with human-generated ones in terms of
sentiment, reading ease, and semantic content. Also, the human evaluation study
showed that AI-generated messages ranked higher in message quality and clarity.
We discuss the theoretical, practical, and ethical implications of these
results.
