[An investigation of mental health in migrant workers in an enterprise].

Objective: To investigate the mental health status in migrant workers in a labor-intensive enterprise and related influencing factors. Methods: Typical sampling was used to perform an investigation in 910 migrant workers in a large foreign-funded labor-intensive enterprise in Shenzhen, China. All the respondents gave informed consent and completed the questionnaire independently and anonymously. The self-reported mental health status was evaluated using the Beck Anxiety Inventory, Beck Depression Inventory, and General Health Questionnaire. Results: Of all the migrant workers in this enterprise, 7.2% had a positive self-reported anxiety symptom, 25.4% had a moderate or severe self-reported depression symptom, and 76.4% had a poor self-reported general health status. Age had significant influence on the self-reported depression symptom (χ(2)=21.968, P<0.05) ; age did not have significant influence on the self-reported anxiety and general health status (χ(2)=6.616、12.498, both P>0.05) . The knowledge of occupational hazards had significant influence on mental health status (χ(2)Depression=47.289, χ(2)General health=21.087, both P<0.05) . The feeling of work had significant influence on self-reported depression and general health status (χ(2)Depression=52.406, χ(2)General health=17.327, both P<0.05) . Attention to self mental health had significant influence on self-reported depression (χ(2)=17.714, P<0.05) , and whether the person wanted to learn the knowledge of mental health had significant influence on self-reported anxiety (χ(2)= 6.145, P<0.05) . Conclusion: The self-reported mental health status in migrant workers is poor and is associated with age, worry about exposure to occupational hazard factors, emphasis on mental health knowledge, and a focus on personal mental health. Therefore, targeted occupational health education and occupational mental health education should be strengthened.
