The chi-square test investigated association of these Selleckchem SGI-1776 groups with demographic variables (age, gender, nationality, and place of residence) and business trip characteristics: length of trip (1–2, ≤28, and >28 d), time before departure that trip was planned (≤2 or >2 mo), time before departure that travel health advice was sought, if at all (<15 or ≥15 d), and source

of travel health advice (company or external). Results were considered statistically significant at p < 0.05 and all analyses were performed using sas Version 9.2. Surveys were returned by 63% (n = 383) of the 608 self-registered FBT in Rijswijk. Twenty-eight respondents did not meet the inclusion criterion of traveling to a malaria-endemic country in the preceding 2 years, and a further 27 FBT did not finish the questionnaire. Only the 328 completed questionnaires that adhered to our inclusion criteria were used for analysis. Demographic characteristics of the study cohort are described in Table 1. The vast majority of FBT were male (n = 311; 95%) and aged between 46 and 60 years (n = 205; 63%), and the most common nationality was Dutch (n = 146; 45%). No statistical association of demographic characteristics

with knowledge level was found. ALK phosphorylation Most FBT (n = 232; 71%) sought travel health advice before their trip. The most common reason given for not seeking advice among those who did not (n = 47; 49%) was that the Resveratrol FBT “knew what to do.” FBT with a longer duration of stay were more likely to consult health advice (p = 0.01). The vast majority of trips were planned less than 2 months before departure (n = 269; 82%), and almost one third (n = 89; 27%) of business travel was arranged within just 2 weeks of departure (Figure 1). FBT who had sought company travel health advice perceived risk significantly more accurately than those seeking advice from external sources (p = 0.03). However, seeking company travel health advice was also significantly associated with an increased tendency

to overestimate the risk of typhoid (odds ratio = 2.03; 95% confidence interval = 1.23–3.34). Among countries with a sufficient sample size (n ≥ 10), the most common destinations of Nigeria (n = 142) and Malaysia (n = 67) produced mean knowledge scores of 4.2 and 3.7 out of 11, respectively. FBT visiting Gabon (n = 23) scored highest, with an average of 4.7 correct responses out of 11. The accuracy of perceived risk for each disease is presented in Figure 2. Correct responses were those agreeing with the actual disease risk. Incorrect responses were those that either overestimated or underestimated risk. On an average, underestimation of risk was 23% more common than overestimation. The majority of individuals underestimated risk for polio (52%), dengue fever (55%), cholera (57%), and influenza (67%). Just 4% of FBT underestimated risk of HIV.
