Predictors related to condom use behaviors based on the theory of planned behavior among female sex workers / 中华疾病控制杂志

ABSTRACT

Objective To identify predictors related to condom use in different tiered female sex workers (FSWs) in Hubei Province. Methods A cross-sectional study was conducted in Hubei Province in 2015 to investigate 816 eligible FSWs by using a multistage sampling method. All data were collected by using a structured questionnaire with scales on condom use, which was designed based on the theory of planned behavior (TPB). A structural equation model (SEM) was used to identify predictors of condom use in the different tiered FSWs. Results It showed that low-tier FSWs used less condom than higher-tier FSWs in commercial sexual behaviors of the last time and during the last month(P<0.001). The TPB scores were significantly different in different tiered FSWs. The scores of PBC in low-tier FSWs were lower than those in higher-tier FSWs (11.43±2.86 vs 12.06±2.87, respectively, P=0.002); But the scores of behavioral intentions were higher than those in higher-tier FSWs (5.47±1.11 vs 5.20±1.15, respectively, P=0.001). The PBC was the major factor related to condom use in low-tier FSWs (effect coefficient=0.55, P<0.001), while the behavioral intention was the major factor related to condom use in higher-tier FSWs (effect coefficient=0.33, P<0.001). Behavioral attitude was the major factor of intention to use condoms for both low-tier (effect coefficient=0.49, P<0.001) and higher-tier FSWs (effect coefficient=0.42, P<0.001). Conclusions Changing the attitude to condom use in FSWs is an important measure to promote the behavior intention. Condom promotion interventions should focus on the perceived behavioral control in low-tier FSWs, and promote the behavior intention in higher-tier FSWs.
