Quality of life in China rural-to-urban female migrant factory workers: a before-and-after study

Background: Rural-to-urban female migrant workers have a lower quality of life compared to the general population. Improving these conditions remains highly challenging. This paper reports the health-related quality of life (HRQoL) of the female migrant workers in an educational project. Methods: In this before-and-after study, a community-based health education intervention was developed to improve female migrant workers' HRQoL and job satisfaction. A factory was selected as the location to implement the trial, using a before-and-after design. The education intervention included distribution and free access to study materials, monthly lectures, and counseling. The primary endpoint was HRQoL, and gynecological disease and job satisfaction were secondary endpoints. We assessed HRQoL at baseline and at 6-month follow-up using the Health Survey Short Form (SF-36). Results: Compared to the baseline assessment, the participants at the 6-month survey reported higher General Health scores (standardized-beta coefficients (Betas) of beta = 0.056; P <0.001), Vitality scores (beta = 0.066; P <0.001), Mental Health scores (beta = 0.062; P <0.001), mental component summary scores (beta = 0.040; P <0.001), and job satisfaction (Odds Ratio [OR] 2.104, 95% confidence interval [CI] 1.837-2.408; P <0.01). Conclusions: A community-based educational intervention, targeted at female migrant workers, appears effective in improving HRQoL and job satisfaction.
