Furthermore, this association was not significant in the small (n = 82) group of high frequency, high duration (>6 trips per year and >5 d per trip) travelers. All groups of travelers, except for the high frequency, high duration group, had lower blood pressure than those who did not travel

at all. There was a considerable dose-response trend with frequent (>6 times/y) international travelers having an OR for hypertension of 0.34 (95% CI = 0.17–0.61). Self-reported systolic and diastolic blood pressure was quantified and if either (systolic or diastolic) met these criteria, the subject was classified as hypertensive. Several negative associations were observed between frequency and duration of travel and self-reported measures

INK 128 in vitro of health status and lifestyle choices. Although there was one exception, the high frequency, high duration LDK378 manufacturer cohort did not show any significance for any of the health measures because this group contained a small number of business travelers (n = 82); statistically, it may not have been a large enough sample size to offset the zero travel group it was compared to. All other groups of international business travelers had a higher OR of alcohol consumption over the recommended limit4 (1–2 drink equivalents per day for men and 1 per day for women), with the high frequency, low duration travel group having the highest OR of 1.63 (95% CI = 1.06–2.05). Those who traveled less frequently and had low travel duration had an OR 1.24 (95% CI = 1.09–1.41) of failing to get the recommended amount of sleep (8 h per night; average of 7–9 h for adults),5 as

compared to their non-traveling peers; the high frequency travel group with the same duration showed an even greater only OR of 1.56 (95% CI = 1.04–2.43) having a sleep deficit. International business travelers also reported a lack of confidence in their continued ability to keep up with the pace of work; there was also a notable dose response observed with the highest odds observed among the high frequency, short duration group OR 2.32 (95% CI = 1.45–3.55). Again, frequency of travel, as opposed to duration of travel, was the most significant driver associated with these adverse health effects. A wide variety of health outcomes and healthy behaviors were similar between all traveler subgroups and the control group. Self-reported overall health status and specific conditions such as back pain and migraine headaches were no different between groups. Healthy behaviors such as adequate physical activity (3–5X/wk 30 min sessions) and adherence to a low-fat diet were similar between groups. Satisfaction with life, work, and physical health status (eg, inconsistent physical activity and high total cholesterol levels) did not differ significantly between groups (Travelers vs non-travelers). Little is known about the impact of frequent or prolonged travel on the perceived health status, lifestyle choices, and personal risks of travelers.
