Real-time electronic adherence monitoring is feasible, comparable to unannounced pill counts, and acceptable

Haberer JE, Robbins GK, Ybarra M, Monk A, Ragland K, Weiser SD, Johnson MO, Bangsberg DR. Real-time electronic adherence monitoring is feasible, comparable to unannounced pill counts, and acceptable. AIDS Behav. 2012;16(2):375-82. Abstract: Second generation electronic medication adherence monitors provide real-time data on pill bottle opening behavior. Feasibility, validity, and acceptability, however, have not been established. Med-eMonitor is a multi-compartment adherence device with reminder and education capacity that transmits data through a telephone connection. Monthly adherence levels were measured for 52 participants over approximately 3 months using the Med-eMonitor (unadjusted and adjusted for participant confirmed dosing) and unannounced pill counts. HIV RNA was assessed … [Read more...]

Interest in technology-based and traditional smoking cessation programs among adult smokers in Ankara, Turkey

Ybarra ML, Bağci Bosi AT, Bilir N, Holtrop JS, Korchmaros J, Emri S. Interest in technology-based and traditional smoking cessation programs among adult smokers in Ankara, Turkey. Tob Induc Dis. 2011;9:10. doi: 10.1186/1617-9625-9-10 Abstract: BACKGROUND: Little is known about the demand for smoking cessation services in settings with high smoking prevalence rates. Furthermore, acceptability of text messaging and Internet as delivery mechanisms for smoking cessation programs in non-developed countries is under-reported. Given the cost effectiveness of technology-based programs, these may be more feasible to roll out in settings with limited public health resources relative to in-person programs. FINDINGS: 148 adult smokers took part in a community-based survey in Ankara, Turkey. Two … [Read more...]

Reasons, assessments and actions taken: sex and age differences in uses of Internet health information

Ybarra M, Suman M. Reasons, assessments and actions taken: sex and age differences in uses of Internet health information. Health Educ Res. 2008;23(3):512-521. Abstract: The Internet is transforming the way in which consumers approach their health care needs. Sex and age are influential aspects of one’s health as well as disease risk and are thus integral components of the emerging picture of health information seekers. Using data from Surveying the Digital Future, Year 4, a nationally representative, longitudinal telephone survey of Americans 12 years of age and older (n = 2010), we examine the reasons for, assessments of and actions taken as a result of health information found online among men and women and older and younger people. Although we tend to think of the Internet as a … [Read more...]
