The objective of this study was to qualitatively explore the components of social networks and their influence on condom use among older female sex workers (FSWs) aged 35 years and older in China. In-depth interviews with 63 older FSWs and 6 focus groups interviews with pimps and owners of roadside salons and hotels were conducted in three Chinese cities. The mean age of participants was 42.6 years old ( SD = 6.9 years) and the mean age of starting sex work was 38.6 years old ( SD = 6.6 years). Two types of networks that influenced condom use were identified: family networks (relationship with children and husbands) and workplace networks (relationship with peers, clients, pimps and owners). Relationships between older FSWs and their children negatively influenced condom use. Low levels of network support and norms regarding condom use were observed in the relationship between older FSWs and their clients, whereas positive social support and norms were prevalent among older FSWs who had frequent contact with peers. Norms for condom use existed among pimps and owners, but were counterbalanced by monetary gains. Future HIV interventions for older FSWs should take the different features of social network components into consideration.
