OBJECTIVE: To explore the smoking status and related influence factors among female sex workers (FSW) and general migrant women (GMW) in Shanghai City, and provide references for health intervention.METHODS: A total of 721 FSW and 675 GMW, recruited by a multiple stage cluster sampling method from Minhang District, Shanghai city, were interviewed. Socio-demographic characteristics and the smoking status were collected by questionnaire interview, while the quality of life (QOL) among participants were evaluated by WHOQOL-BREF.RESULTS: The smoking rate within FSW (39. 1%) was significantly higher than GMW (2.7%). When compared with GMW, QOL scores among FSW were signifiantly lower in four domains ( physio-domain F = 55. 50, P <0. 001, psychi-domain F =59. 07, P <0. 001, social relationship domain F = 157. 46, P < 0. 001 and environmental domain F = 65. 08, P < 0. 001). The multivariate analysis showed that higher score of psychi-domain (OR = 0. 893, 95% CI 0. 839 - 0. 950), married (OR =0. 590, 95% CI 0. 395 - 0. 880), older age group (OR =0. 590, 95% CI 0. 395 - 0. 880) and GMW (OR = 0. 077, 95% CI 0. 043 - 0. 141.) were protecting factors for smoking, whereas not having a permant partner (OR = 1. 610, 95% CI 1. 114 - 2. 328), staying in Shanghai ≤ 1 year (OR = 1. 537, 95% CI 1. 109 - 2. 132) and low income group (OR = 1. 956, 95% CI 1. 445 - 2. 650) were risk factors for smoking.CONCLUSION: The rate of smoking is significantly higher in FSW, when compared: with GMW. The effective preventive strategies which concentrate on the influence factors should be taken to reduce smoking in the target population.
