Risk factors: a normal relationship with her mother-in-law (OR=5.309; 95% CI 1.122–4.184), artificial insemination (OR=4.339; 95% CI 1.492–12.623), no exercise during pregnancy (OR=2.666; 95% CI 1.177–6.039), low self-efficacy (OR=4.253; 95% CI 1.518–11.916), low social support (OR=2.371; 95% CI 1.206–4.661), poor sleep quality (OR=2.134; 95% CI 1.131–4.027), existence of anxiety symptoms (OR=17.654; 95% CI 8.494–36.689).Conclusion The prevalence of depression symptoms is lower than that in developing countries, but due to the large population base of China, the problem should still be taken seriously.
