Wireless substitution: state-level estimates from the National Health Interview Survey, January 2007-June 2010
Blumberg SJ , Luke JV , Ganesh N , Davern ME , Boudreaux MH , Soderberg K . Natl Health Stat Report 2011 (39) 1-26, 28 OBJECTIVES: This report presents state-level estimates of the percentage of adults and children living in households that did not have a landline telephone but did have at least one wireless telephone. National estimates for the 12-month time period from July 2009 through June 2010 indicate that 23.9% of adults and 27.5% of children were living in these wireless-only households. Estimates are also presented for selected U.S. counties and groups of counties, for other household telephone service use categories (e.g., those that had only landlines and those that had landlines yet received all or almost all calls on wireless telephones), and for 12-month time periods since January-December 2007. METHODS: Small-area statistical modeling techniques were used to estimate the prevalence of adults and children living in households with various household telephone service types for 93 disjoint geographic areas that make up the entire United States. This modeling was based on January 2007-June 2010 data from the National Health Interview Survey, 2006-2009 data from the American Community Survey, and auxiliary information on the number of listed telephone lines per capita in 2007-2010. RESULTS: The prevalence of wireless-only adults and children varied substantially across states. State-level estimates for July 2009-June 2010 ranged from 12.8% (Rhode Island and New Jersey) to 35.2% (Arkansas) of adults and from 12.6% (Connecticut and New Jersey) to 46.2% (Arkansas) of children. For adults, the magnitude of the increase from 2007 to 2010 was lowest in New Jersey (7.2 percentage points) and highest in Arkansas (14.5 percentage points). |
Reevaluating the need for concern regarding noncoverage bias in landline surveys
Blumberg SJ , Luke JV . Am J Public Health 2009 99 (10) 1806-10 OBJECTIVES: We used recent data to reexamine whether the exclusion of adults from households with no telephone or only wireless phones may bias estimates derived from health-related telephone surveys. METHODS: We calculated the difference between estimates for the full population of adults and estimates for adults with landline phones; data were from the 2007 National Health Interview Survey. RESULTS: When data from landline telephone surveys were weighted to match demographic characteristics of the full population, bias was generally less than 2 percentage points (range = 0.1-2.4). However, among young adults and low-income adults, we found greater bias (range = 1.7-5.9) for estimates of health insurance, smoking, binge drinking, influenza vaccination, and having a usual place for care. CONCLUSIONS: From 2004 to 2007, the potential for noncoverage bias increased. Bias can be reduced through weighting adjustments. Therefore, telephone surveys limited to landline households may still be appropriate for health surveys of all adults and for surveys of subpopulations regarding health status. However, for some behavioral risk factors and health care service use indicators, caution is warranted when using landline surveys to draw inferences about young or low-income adults. |
