Mobile Health and Exposures to Health and Risk Messages
People who communicate health and risk information are often trying to determine new and innovative ways to reach members of their target audience. Because of the nearly ubiquitous use of mobile phones among individuals in the United States and the continued proliferation of such devices around the world, communicators have turned to mobile as a possible channel for disseminating health information. Mobile health, often referred to as mHealth, uses mobile and portable devices to communicate information about health and to monitor health issues. Cell phones are one primary form of mHealth, with the use of cell phone features such as text messaging and mobile applications (apps) often used as a way to provide health information and motivation to target audience members. Text messaging, or short message service (SMS), is a convenient form for conveying health information, as most cell phone owners regularly send and receive text messages. mHealth offers benefits over other channels for communicating health information, such as convenience, portability, interactivity, and the ability to personalize or tailor messages. Additionally, mHealth has been found to be effective at changing attitudes and behaviors related to health. Research has found mobile to be a tool useful for promoting healthy attitudes and behaviors related to a number of topic areas, from increased sexual health to decreased alcohol consumption. Literature from health communication and research into mHealth can provide guidance for health communicators looking to develop an effective mHealth intervention or program, but possible concerns related to the use of mobile need to be considered, such as concerns about data security and participant privacy.
