Temporal and Thematic Analysis of Promotional Waterpipe-Related Posts on Twitter/X in the US.

Abstract

Waterpipe tobacco smoking (WTS), also known as hookah, shisha, or narghile, is particularly popular among young people in the United States (US). WTS poses serious health risks similar to those of cigarette smoking. Using the Twitter/X streaming API (Application Programming Interface), we collected 4,853,562 tweets between March 9, 2021, and March 14, 2023, using waterpipe-related keywords, such as "hookah" and "waterpipe". After geographical filtering to identify tweets from the US and keyword filtering for the promotional content, we identified 23,803 promotional waterpipe-related tweets. We examined trends in the posting time of these promotional waterpipe-related tweets and identified prevalent topics from these tweets using the BERTopic (Bidirectional Encoder Representations from Transformers) modeling. The number of promotional waterpipe-related tweets showed an overall decreasing trend during the study period. The posting of promotional waterpipe-related tweets was more active later in the day. Major topics in the promotional tweets included "Promotion from hookah lounges and online hookah business" (63.97%, 15,227/23,803), "promoting hookah parties and events" (32.26%, 7,679/23,803), and "promoting engineered and durable hookah products" (3.77%, 897/23,803). Twitter/X accounts posting waterpipe-related promotional content have substantial variations in the number of relevant tweets (mean = 2.28, SD = 12.22) and followers (mean = 5,937, SD = 76,770). This study demonstrates a significant social media activity in promoting waterpipe tobacco smoking. Our findings underscore the urgent need to regulate the promotional content of WTS on social media and promote public health education messages on social media to counteract the promotion of WTS.
