To improve health interventions targeted at globally mobile populations, an improved understanding of their health practices is needed. In particular, identifying
sources of health advice and barriers to appropriate pre-travel care is essential. In this study, we surveyed US residents traveling PI3K inhibitors in clinical trials to international destinations who were departing from Boston Logan International Airport in 2009. The purpose was to collect demographic data on travelers, to identify sources of health information, and to understand barriers to the pursuit of health information prior to departure. We surveyed a convenience sample of travelers awaiting departure from Boston Logan International Airport on an international flight or on a domestic flight with an immediate connection to an international flight.
Representatives of the Boston Public Health Commission, the Massachusetts Port Authority, and the Boston Logan Airport Fire Rescue and Police were involved in the development and administration of the Proteasome inhibitor surveys. Surveys were administered from February through August 2009. Survey respondents filled out questionnaires regarding their destination and provided demographic data about themselves and any travel companions. Only one survey was collected per traveling group or family. We questioned individuals as to whether they had pursued health information from specific sources, including check the internet (in particular the CDC Travelers’ Health website), primary care providers, travel medicine specialists, travel agents, employers, and travel publications. We also asked them to indicate whether they were carrying prescription medications related to their trip. The majority of surveys (>90%) were administered in English; surveys were also available in Spanish, Portuguese, French Creole, Chinese, Hindi, and
Arabic. Geographic destinations were classified into income categories according to the 2009 World Bank World Development Report (http://econ.worldbank.org).3 We divided survey respondents into those traveling to countries classified as low and low-middle income (LLMI) or upper-middle and high income (UMHI) by the World Development Report. Travelers were classified as “visiting friends and relatives” (VFR) according to a definition outlined by the US Centers for Disease Control and Prevention (CDC), ie, an immigrant to the United States who returns to his or her homeland, a lower income country, to visit friends or relatives.4 Also included in the VFR category were family members who were born in the United States. Travelers who did not meet the above definition of VFR travel were classified as “visiting family. Survey data were entered and managed in Microsoft Access (Microsoft Corp, Redmond, WA, USA). We performed bivariate and multivariate analyses using SAS 9.2 (SAS, Cary, NC, USA) and SUDAAN 10.
