Language Analysis of Myspace Profiles

Abstracts / 46 (2010) S17–S81
this study would empower adolescents to take on responsibility for their own health which they can build on and develop as future purveyors on health services. The internet as a source of health information is a powerful tool; we now need to ensure the tool is developed in line with adolescent wants. The internet provides a means to bring health professionals and adolescents together in a way that perhaps best meets the needs of the adolescents. The development of accurate and adolescent-friendly websites can best be achieved by directly involving them in creating resources - as they do appear to know what they want.

60. TELEHEALTH SUPPORT TO DECREASE INSULIN RESISTANCE IN OVERWEIGHT AND OBESE ADOLESENTS: A PILOT STUDY Alberta S. Kong, MD, MPH, Keri Bolton Oetzel, PhD, MPH, Rosemary S. Wold, MS, RD, LD, Carol Hartenberger, RN, MPH, Betty J. Skipper, PhD, Mark R. Burge, MD, Jane McGrath, MD, Sally Davis, PhD. University of New Mexico Purpose: Telehealth was tested to support providers working in a rural school-based health center (SBHC) with reducing insulin resistance in overweight and obese adolescents who were identified as being at risk for type 2 diabetes by the American Diabetes Association guidelines. We hypothesized that insulin resistance would decrease in students seen in the rural SBHC similarly to students seen in an urban SBHC where providers did not receive telehealth support but had access to usual consult services. Methods: A quasi-experimental design was used. The rural SBHC provider received medical and behavioral specialty consultations through telehealth bimonthly. The urban SBHC provider received no telehealth support but had access to usual phone consult services. A convenience sample of 54 non-diabetic overweight/ obese adolescents was enrolled for six clinical visits within a school year. Measures included insulin resistance by homeostasis model assessment (HOMA-IR), BMI z-score, self-reported sweetened beverages intake, self-reported fruits and vegetables intake, self-reported time in moderate or vigorous physical activity, and quality of life (QOL with PedsQL). Pre-post changes for participants were compared between groups using two-sample t-tests for normally distributed data and Wilcoxon rank sum tests for skewed distributions. Results: Forty-eight students (mean age 15 years, 73% female, 87% Hispanic) completed all visits. HOMA-IR and sweetened beverages consumption decreased significantly from baseline to postintervention in both rural (p ¼ .05 and p < .01 respectively) and urban students (p ¼ .04 and p < .001, respectively). Compared to urban students, rural students increased median time in moderate and vigorous physical activity (-60 vs. 158 minutes/week respectively, p ¼ .08) and achieved significantly greater increases in QOL scores (.7 6 1.8 vs. 6.4 6 2.1 respectively, p ¼ .05). Significant increase in fruits and vegetables intake was seen only in urban students (p ¼ .02). There were no significant changes in BMI z-scores in either group. Conclusions: Telehealth support was feasibly delivered to the rural SBHC. Promising health improvements of rural students comanaged with academic medical and behavioral specialists through telehealth deserves further investigation as a strategy to help rural providers work with teens on reducing insulin resistance.

LANGUAGE ANALYSIS OF MYSPACE PROFILES Brian Jenssen, BA6, Nicola Gray, RPh, PhD3, Kevin Harvey, PhD4, Nichole Daluga-Guenther, MPH2, Laura Salazar, PhD1, Jonathan Klein, MD, MPH5, Ralph DiClemente, PhD1. 1Emory University, Rollins School of Public Health; 2Rollins School of Public Health; 3University of Nottingham; 4University of Nottingham, Division of Social Research in Medicines and Health; 5University of Rochester and the AAP Julius B. Richmond Center; 6University of Rochester School of Medicine and Dentistry Purpose: 65% of online teenagers have a profile on MySpace, Facebook, or other social networking sites. Concern has been raised over the information shared and language used by adolescents in online communities, including the display of health risk behaviors through publicly accessible information. We performed an analysis of MySpace pages viewed by a random sample of adolescents to describe the language used in public and privately accessible profile pages. Methods: Adolescents age 14-17 with home Internet access were recruited using list-assisted random digit dialing methods. Webtracking software was installed on the home computer of each eligible, consenting participant. All web pages viewed by participants during a 30-day period between December 2004 and February 2005 were captured and stored on secured servers, where they could be viewed as originally displayed. A text corpus was created from the profile sections from all MySpace pages viewed by the participants. The corpus, with identifiers removed, was loaded into Antconc 3.2.0. for MAC concordance software. The Adolescent Health Corpus (AHC) (a million-word text corpus of email health questions from adolescents to the UK ‘‘Teenage Health Freak’’ website) was the reference corpus for keyword comparisons. A word frequency list was generated from the MySpace profile corpus (MSPC), followed by exploration of concordances and collocates of words of interest. This analysis combination provided a multifaceted description of the linguistic features of the profiles. Results: The 346 participants viewed 1.2 million web pages, including approximately 28,000 from MySpace. 1309 unique profile sections were identified, yielding a 177,584 word corpus. The top ten MSPC words included the personal pronouns ‘‘I’’ (#1) and ‘‘me’’ (#6), the possessive pronoun ‘‘my’’ (#9), and the second person pronoun ‘‘you’’ (#8). Concordance analysis showed the context of these words was often an attempt to engage the profile reader in a conversation. The language used reflected the profile owner offering personal demographic information, such as name, age, hometown, school, interests, and the type of people they would like to meet. Information detailing high risk behavior was rare. No words identifying sexual acts, drinking alcohol, and/or smoking cigarettes or marijuana featured in the top 250 words: the word ‘‘smoke’’ or ‘‘smoking’’ appeared only 66 times (in 3.7% of 1309 profiles). The top self-generated MSPC content word was ‘‘love’’ (#16), with profile owners professing love for family, friends, significant others, or activities such as writing, listening to music, or playing sports. In keyword analysis it was notable that the top MSPC content word ‘‘love’’ was significantly more likely to occur in the MSPC, and the top AHC content word ‘‘sex’’ significantly more likely to occur in the AHC (#374 in MSPC). Conclusions: MySpace profiles viewed by adolescents infrequently contain references to high risk behaviors. Instead, these pages offer first person narrative accounts of the profile owners’ demographics, personal interests, and everyday experiences. Social network sites rarely contain provocative details about their high risk behavior and more often share innocuous information about teens’ personal lives.
