Objective In order to understand the situations of HBsAg positive rate and ALT disorder among new college students and provide evidence for prevention of HBV infection. Method The situations of HBsAg positive rate and ALT disorder among new college students are statistically analyzed by year

area

urban and rural. Results The HBsAg positive rate among all the new students is 5.54 %.The ALT disorder rate among them is 0.85 %.The HBsAg positive rate among the new students is 6.65 % for 2002

6.35 % for 2003 and 3.95 % for 2004 respectively.The HBsAg positive rate among the students from the southern part of Jiangsu is 6.05 % and that for the northern Jiangsu students is 5.04 %.The HBsAg positive rate among the new students from urban areas is 4.63 %

and that for the rural students is 6.27 %.The HBsAg positive rate in the male students is 8.53 %

and that for the female students is 4.45 %.The HbsAg positive rate for male is higher than that for female （χ2=8.75

p<0.05）. Conclusion The HBsAg positive rate had declined by year. The HBV infectious rate among male students is higher than that for female.The difference of HBV infectious rate between the different areas is not significant.
