Promoting contraceptive use among female rural-to-urban migrants in Qingdao, China: a comparative impact study of worksite-based interventions

Background: We conducted a comparative study in worksites to assess the impact of sexual health promoting interventions on contraceptive use among female rural-to-urban migrants. Study design: In Qingdao ten manufacturing worksites were randomly allocated to a standard package of interventions (SPI) and an intensive package of interventions (IPI). The interventions ran from July 2008 to January 2009. Cross-sectional surveys at baseline and end line assessed the sexual behaviour of young female migrants. To evaluate the impact of the interventions we assessed pre- and post-time trends. Results: From the SPI group 721 (baseline) and 615 (end line) respondents were considered. Out of the IPI group we included 684 and 603 migrants. Among childless migrants, self-reported contraceptive use increased significantly after SPI and IPI (adjusted odds ratio [aOR] = 3.23; 95% confidence interval [CI] = 1.52−6.84; p < 0.01 and aOR = 5.81; 95% CI = 2.63−12.80; p < 0.001, respectively). Childless migrants older than 22 years reported a greater use after IPI than after SPI. Conclusion: Implementing current Chinese sexual health promotion programmes at worksites is likely to have a positive impact on migrant women working in the manufacturing industry of Qingdao. More comprehensive interventions seem to have an added value if they are well targeted to specific groups
