The purpose of this study was to examine the stage of secondhand smoke avoidance behavior of adolescents in rural areas of Vietnam and the related factors affecting such behavior. The participants were recruited from two middle schools located in Hai Thuong and Trieu Trach commune, Vietnam. Data were collected in January 2016 by distributing and collecting a self-administrated questionnaire. The collected data were analyzed (n = 166) using SPSS 21.0 for frequency, percentage, and ordinal logistic regression. The largest proportion of secondhand smoke avoidance behavior was classified in maintenance (41.6%), followed by action (19.9%), preparation (15.1%), pre-contemplation (13.3%), and contemplation (10.2%) stages. The factors related to higher secondhand smoke avoidance behavior were higher self-efficacy (p = 0.003) and more frequent discussion with parents about dangers of smoking (p = 0.001). The findings indicated that self-efficacy of avoiding secondhand smoke and discussion with parents were associated with secondhand smoke avoidance behavior of adolescents. These findings can be used for developing education programs to prevent secondhand smoke for adolescents in Vietnam.
