Abstract:
Objective To evaluate the middle-stage effect of health literacy intervention in occupational groups of Minhang District in Shanghai and provide suggestions for the later intervention.
Methods Quasi-experimental method was used to randomly select 200 employees respectively in the two enterprises in Minhang District of Shanghai as participants, randomly setting one enterprise as the intervention group, the other as the control group. The intervention was conducted through participatory health education activities such as prized quiz about health literacy knowledge, posters collection, health consultation, etc. The middle-stage effect of the intervention was evaluated through comparing pre-and middle-stage results of health literacy of occupational groups.
Results In this survey, the literacy level of participants' healthy lifestyle and behavior as well as chronic diseases prevention in the intervention group improved after the middle-stage intervention, but their literacy levels were respectively the lowest among the three aspects of health literacy content and the five kinds of major health problem related literacy. After considering the demographics, the overall health literacy level of participants in the intervention group improved a lot after the intervention(OR=5.154, P< 0.001), while such improvement was not reflected in the control group(OR=0.747, P> 0.05). The overall health literacy level of participants in the intervention group was not associated with age, gender, education background, and average family monthly income(P> 0.05), while in the control group, the male and low-income participants' overall health literacy levels were lower than female and high-income workers'.
Conclusion The middle-stage effect shows that the participatory health intervention could improve the level of health literacy of occupational groups. The later intervention should take male, lowincome workers as key intervention groups, and make healthy lifestyle and behavior as well as chronic diseases prevention literacy as major intervention dimensions.
