To test for significant differences between groups, we used two-sided t-tests (continuous variables) or chi-square tests (categorical variables), as appropriate. We performed a logistic regression analysis to evaluate the association between demographic factors [age (continuous), gender (male or LGK-974 female), country of birth (foreign-born or US-born), fellow travelers (traveling alone or not), duration of travel (>14 days or ≤14 days), and purpose of travel]

and the likelihood of pursuing health information among travelers to LLMI countries. The Partners Healthcare Human Research Committee approved this study. No personally identifiable information was collected from study respondents. A total of 1,254 travelers, all of whom resided permanently in the United States, completed the survey. A total of 476 survey respondents (38%) were traveling to LLMI countries and 778 survey respondents (62%) were traveling to UMHI countries. The four most common LLMI country destinations among survey respondents were the Dominican Republic (n = 129), India (n = 55), China (n = 47), and Turks and Caicos (n = 43). A total of 61 survey respondents were visiting countries in Africa, including 45 visiting sub-Saharan Africa. Table 1 compares demographic Ibrutinib purchase characteristics of survey respondents traveling to LLMI countries and UMHI countries. Travelers to LLMI countries differed significantly from travelers to UMHI countries in a number of attributes. In particular,

travelers to LLMI countries were younger and more likely to be foreign-born. The four most common foreign birthplaces among survey respondents were India (n = Glutathione peroxidase 42), the Dominican Republic (n = 41), China (n = 16), and Haiti (n = 15). Travelers to LLMI countries pursued trips of longer duration; visiting family and performing volunteer work were more frequently reported as the purpose of travel to LLMI countries (Table 1). Of note, 98 (21%) travelers to LLMI countries fit the CDC criteria for VFR.4 Travelers

to LLMI traveled more frequently with children under the age of 5 (17% of respondents to LLMI countries vs 8% of respondents to UMHI countries, p = 0.02). Overall, 54% of survey respondents traveling to LLMI countries pursued any health information prior to departure. Among travelers to LLMI countries, 21% reported verifying that their immunizations were up to date prior to departure, and 36% reported carrying a prescription medication for travelers’ diarrhea. A total of 364 travelers to LLMI countries were visiting countries that included areas endemic for malaria; 20% of these individuals reported carrying a prescription antimalarial drug with them. By multivariate analysis, several factors were associated with failing to pursue health information among travelers to LLMI countries (Table 2). Being foreign-born, traveling alone, traveling for less than 14 days, and traveling for vacation each predicted higher odds of not pursuing health information, after controlling for other variables.
