Public Health, Martin Luther King and Cell Phones in Kentucky
At the opening of the 2011 American Public Health Association (APHA) Conference in Washington, D.C., last week, a collection of very provocative opening presentations challenged all 12,000-plus attendees to work harder for the health of those most in need. To view a few of the presentations, including one from former Senate Majority Leader Tom Daschle, visit APHA's YouTube Page .
During that same opening session, attendees were encouraged to visit the new Martin Luther King, Jr. Memorial. I did that and found the monument very thought-provoking. Below is a quote and picture from the memorial. If you've been there, what did you think?
The ultimate measure of a man is not where he stands in moments of comfort and convenience, but where he stands at times of challenge and controversy. - Martin Luther King
The APHA Conference featured more than 1,000 scientific presentations, including one based on our work with the Foundation for a Healthy Kentucky on the Kentucky Health Issues Poll (KHIP). Take a quick look at our slides:
This presentation reviewed how the addition of surveys with the cell phone-only population can affect the results of traditional landline surveys, and considered the costs and benefits of adding this hard-to-reach, but growing, population of telephone users.
KHIP is a random-digit-dialing telephone health opinion survey of more than 1,500 adults that has been conducted annually since 2008. Landline-only samples fell short of U.S. Census estimates of young and non-white people living in Kentucky. Therefore, a sample of more than 200 cell phone-only households was included in the 2009 and 2010 KHIP. In both years, the unweighted cell phone-only sample was significantly more likely than the unweighted landline sample to be non-white and to be younger than 35 years old.
Combining landline-only and cell phone-only surveys resulted in improved sample coverage, but did this improved coverage affect results? The answer is yes. The cell-phone sample included considerably more uninsured Kentuckians than would have otherwise been possible with a landline-only sample.
