[Air-l] Adolescents on the Web

Greetings, I was wondering if anyone knew of any statistics on the most popular search engines used by teenagers, and/or a listing of the most popular sites visited by teen girls? I am beginning my dissertation which will examine the impact of online health information on the health behaviors of adolescent girls (specifically diet and fitness). I am familiar with the work of Dina Borzekowski, but if any of you are aware of other major studies in this area or are interested in this topic I am eager to hear from you. You may respond directly to me. Thanks in advance, Julie T. Marks Doctoral Candidate The University of North Carolina at Chapel Hill School of Public Health
