Abstract: Objective  To explore the feasibility of carrying out tuberculosis(TB) health education activities and determine the effective way of educating passengers on the train, and then provide recommendations on designing large-scale TB health education activities on the train. Methods  A small-scale TB publicity was carried out through posters and broadcast on 4 trains with the duration of 3 months. During the publicity，207 passengers were inquired about the exposure of the publicity and knowledge, attitude related to TB along with the preferred channel to obtain TB knowledge on the rain by a uniform questionnaire, who were in one hard-seat compartment and one hard-sleeper compartment, randomly selected in one of the four trains according to the random number table  (207 questionnaires were returned among the 211 issued and all the 207 questionnaires were valid). Twenty passengers and 12 train conductors were interviewed about the willingness and suggestion on publicity about TB on the train. Results  64.0%（121/189）of the passengers either exposed to the broadcast or the posters. The general awareness rate of key TB massage among the train passengers was 52.4%(525/1002) with the average score of （2.48±1.21）(full score is 5). 41.9%(83/198) of the passengers selected showing more concern when their neighbors got TB. The top four preferred channel for the passengers were broadcast, television, posters, and pamphlets with selecting rates respectively 64.3%(133/207), 36.7%(76/207), 30.0%(62/207) and 24.6%(51/207). The passengers were divided into four groups to compare the possibility of obtaining high score (≥3) of TB knowledge according to the exposure of broadcast and poster: those exposed to both poster and broadcast (group 1), those exposed to broadcast only (group 2), those exposed to poster only (group 3),and those exposed to neither poster nor broadcast (group 4). The results of logistic regression analysis show that compared to group 4,group 1 and 2 were more likely to have high scores with possibility of 2.167 times（β=0.773；Wald χ²=4.369；P=0.037；OR=2.167,95%CI=1.049-4.475）and 3.374 times （β=1.216；Wald χ²=5.177；P=0.023；OR=3.374,95%CI=1.184-9.618）respectively,while the group 3 shows no difference（β=0.066；Wald χ²=0.023；P=0.88；OR=1.068,95%CI=0.454-2.512）.Based on the result, broadcast was more effective than poster in publicity on the train. Among the interviewees, 18 passengers were willing to learn TB knowledge and all the 12 conductors were willing to offer the help; while 17 passengers and 10 conductors regarded broadcast as the most effective way to convey TB messages to them when on board a train. Conclusion  It is feasible to carry out health education activities about TB knowledge on the train; broadcast should be given the priority when concerning the ways of publicity about TB on the train, however, entertaining programs related to TB message and increased playback frequency is a must to improve its effectiveness of publicity.
