Logistic regression was used in statistic analysis. Results The hepatitis B vaccination rate was 59. 8%（ 95% confidence interval95% CI:57. 3%- 62. 4%）. The vaccination rate was associated with age,marriage status,educational level,living condition,and whether with health education（ P ＜ 0. 05 for all）.
