title: [Prevalence status for smokers of undergraduates in Huaihua and the influential factors].
abstract: OBJECTIVE
  To investigate the prevalence status and the influential factors for smokers of undergraduates in Huaihua.
  
  
  METHODS
  The undergraduates from different grades and different professions in Huaihua were selected randomly and investigated using a self-developed questionnaire. The influential factors for smokers of students were analyzed using a Chi-square test and a logistic regression.
  
  
  RESULTS
  A total of 1 050 undergraduates were surveyed in our study. Among them, 973 were valid. The rate for students with a habit of smoking was 21.17%. 53.7% of smokers began to smoke at the stage of primary and high schools. The main reason for smoking was due to curious (47.1%) or depressive (45.2%). The male students were more likely to smoke than female students (OR=6.730). The attitudes of parents on smoking, such as no intervention, were important risk factors that affect the children's behavior on smoking (OR=1.866).
  
  
  CONCLUSIONS
  The periods in primary and high school are the most possible time for student to begin smoking. The curiosity and depression are the most risk factors, and the gender and family education are also the important factors that affect the behavior of undergraduates on smoking.
