[Research on the smoking status and influence factors among female sex workers and general migrant women in Shanghai City]

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.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.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, P0. 001, psychi-domain F =59. 07, P0. 001, social relationship domain F = 157. 46, P0. 001 and environmental domain F = 65. 08, P0. 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.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.
