Objective To evaluate the life quality in front and at the back of the cure of the floating population tuberculosis patients.Methods The SF-36 scale was applied to the new smear-positive pulmonary tuberculosis patient in floating population using face to face interview in Shenzhen 6 districts.The contrast was tuberculosis patient in the population of the household register,the people stayed temporarily in the same term.Results The score of general health(43.36 ± 15.67),vitality(57.96 ± 16.54) and mental health(61.46 ± 14.26) in the floating population was lower than the appraisal result with the population of the household register(49.28 ± 17.85,66.38 ± 17.03 and 66.70 ± 15.12),the people stayed temporarily(45.00 ± 17.22,60.99 ± 16.59 and 63.13 ±13.71 ) (P ＜ 0.05 ).It was still lower than the other two groups after 2 (3) months and 6 (7) months (P ＜ 0.05 ).But the score of social functioning in floating population ( 88.92 ± 14.88 ) was higher than the other two groups (82.62 ± 14.44,68.02 ± 27.30).The change rate of general health ( (76.05 ± 132.82) ％,(69.32 ± 111.98 ) ％and (48.36 ± 101.31 ) ％ ) and social functioning scores( (46.49 ± 85.18 ) ％,( 26.33 ± 50.25 ) ％ and ( 51.09±73.44)％ ) were significant difference in the three groups(x2 =12.088,P=0.002;x2 =11.611,P=0.003).The change rate of the general health score in floating population was higher than the household register population and people stayed temporarily.Conclusion It is necessary to implement the management in whole course to the floating population tuberculosis patients.
