Academic researchers who study child and adolescent health have a responsibility to disseminate their research to parents in ways that can facilitate behavior change. Research on the most effective way to communicate health information to parents, especially among low-income parents, is limited (1-4). The Internet and its related information-sharing applications, specifically Web 2.0 social media, are innovative methods for communicating child health information to parents. Our primary objective was to collect and analyze qualitative data to determine whether social media is a valuable (ie, worthy investment of health promotion resources) and effective way to communicate health information to low-income parents in an effort to promote children's health.

We selected participants through homogenous, purposeful sampling by using standard recruitment guidelines (5). Inclusion criteria were 1) being a parent of a child who attends a school in a designated central Texas school district and 2) being English-speaking. Students who attended these schools were predominantly Hispanic (79%) and economically disadvantaged (81%), as determined by eligibility for public assistance (6-7). We distributed flyers with information about focus groups at a school-based children’s health clinic, which is the only source of pediatric care in the area and which serves primarily low-income, Hispanic families (8).

Study approval was obtained from the University of Texas Health Science Center at Houston institutional review board, and voluntary informed consent was obtained. We conducted 4 focus groups (N = 19; mean no. of participants, 4.75; range, 2-6 participants) at public libraries in October 2010. The groups lasted 45 to 60 minutes and included a discussion, prompted by questions (Box) on the use of social media and willingness to use social media as a health information resource. Participants each attended only 1 group and were provided an incentive for their time.

We collected demographic information and administered the English version of Newest Vital Sign, which determines the likelihood of low health literacy. The test is reliable and correlates with the Test of Functional Health Literacy in Adults (TOFHLA) (9). We recorded and transcribed each group's comments for analysis with the classic analysis strategy described by Krueger and Casey (5). Emerging themes and areas of agreement in and across groups were identified, as were trends in the number of participants who made the same comment and the intensity or personal context associated with each.

Most participants were female, used some form of government assistance, and had access to the Internet (Table). Social networking sites (eg, Facebook) were the most commonly used application among participants, mainly as a method of staying in contact with friends and family. Regular use of these sites was reported to be low, which was not due to lack of access but rather lack of time, given participants' busy schedules or other priorities while online. One participant stated, "[I have an account] on Facebook, and I really don't have time to go to it." Some participants had access only in the community (eg, at the public library), where time limits were placed on users.

The results were mixed on whether participants would use social media as a way to obtain information about their children's health. Although some participants were open to exploring a new option, many more objected, citing lack of credibility most often. Participants preferred to obtain health information face-to-face from someone they trusted, particularly when the information concerned the health of their children. According to a participant,

I'm not sure I would use [social media], because I would have to trust [the] person. If they are talking about my kids' health, I don't want some stranger on the computer telling me they need this, and this, and this.

Several participants stressed the desire to consult their doctors, because of their difficulty in trusting online information. However, when participants were asked how they would feel if the social media sites were run by university, government, or nonprofit organizations, they were more amenable to the idea. One participant stated, "It might be a bit more trustworthy than taking someone's information that is just kind of out there."

Although their frequent use of it was low, participants did use social media; therefore, it has value as part of an overall communication strategy that includes more traditional channels. Our results correspond with current trends in social media use, which have shown an increasing trend in the number of people who use social media applications (10-11). Nevertheless, to employ this new channel for information dissemination, barriers (ie, lack of time to use social media and perceived lack of integrity of health information found there) must be overcome.

Our study had several limitations. The sample size was small, so the results are less generalizable to the overall population. Nonetheless, we found several clear themes that can be applied in the context of other research. Another limitation is that participants were selected from a convenience sample from 1 region in Texas; however, our sample was comparable to others that may have been selected from other low-income, minority communities (12-14). Finally, although Hispanic representation in the sample was good, focus groups were conducted in English; therefore, our findings may not apply to Spanish-speaking low-income parents. Further research is needed in this population.

Health messages delivered to low-income parents must come from perceived experts and should be personalized, which may help establish a relationship between information provider and seeker and overcome the barrier of lack of credibility and trust. Parental time is a valuable resource, and social media outlets are most often used by parents as a means for maintaining personal relationships rather than as sources of information. More effort, investment, and creativity are needed to draw this audience to social media sites that contain health information. Future research should focus on ways to most effectively use this new channel of communication in low-income populations, which will require larger-scale quantitative investigation of the trends identified in this exploratory investigation.
