Health risks during travel: A population-based study amongst the Hong Kong Chinese

Abstract

Between June 1998 and October 1998, a cross-sectional survey was carried out in Hong Kong on 369 Chinese residents who had travelled to mainland China or elsewhere overseas in the previous 12 months. The aim was to collect data on which intervention strategies to minimise travel-related illness among the public might be based. In interviews by telephone, information on travel-related health problems, factors related to such problems, and barriers in the acquisition of travel-health advice was gathered using a structured, pre-tested questionnaire. Most of the subjects had travelled to countries in the Asia-Pacific region, with mainland China as the most popular destination (44%), followed by Thailand (14%). Overall, 16% of the respondents had developed health (mainly alimentary and respiratory) problems during or after their travel, 8% had received pre-travel health advice but 59% reported taking some form of precaution against travel-related illness. Although only 12% had lost at least a day of work or travel because of their travel-related health problems, 40% perceived themselves at risk of future travel-related illness, and 68% said they were willing to pay for the prevention of travel-health problems. Younger travellers and those who perceived relatively few health risks in future travel were relatively more likely to have developed health problems. There appears to be a clear need to develop appropriate health-promotion strategies to reduce travel-health risks among the residents of Hong Kong and the rest of the Asia-Pacific region.
