Evaluating health warning messages specific to waterpipe smoking among university students in Jordan

Health warning messages specific to waterpipe smoking (WPS) have not been tested enough in literature. This study evaluated university students' response to such messages. Specifically, this study (1) assessed the extent to which certain warning messages and pictorial signs motivate participants to quit WPS smoking; (2) identified the best location to place the warning signs of waterpipe as perceived by participants; and (3) assessed participants' intention to quit WPS.

A descriptive, cross-sectional design was used to collect data from 397 university students in Jordan using an Internet-based survey. The following data were collected: intentions regarding WPS, response to nine warning messages, and responses to four pictorial signs.

The message that had the highest motivation to quit smoking was " WPS during pregnancy can harm your baby" (79.3%), whereas the highest pictorial sign was regarding "Protect your children" (64.2%). Most (69.5%) participants believed that WPS products and accessories should contain warnings, and the best suggested location was the pipe handle (52.4%). Participants who reported quitting WPS and those who had an intention to quit had significantly higher responses to both types of health warning labels (HWLs).

Both text-only and pictorial HWLs were found to encourage quitting WPS among university students. Knowing that participants are having an intention to quit mandates extra efforts to make WPS experience less appealing through reminding them regarding its harms.

Support is needed by health care providers to put those effective health warning messages in action. Furthermore, providers can use such health warnings in motivating their patients to quit WPS.
