Prevalence of depressive symptoms and correlated factors among pregnant women during their second and third trimesters in northwest rural China: a cross-sectional study

Abstract

Abstract Background The depression mood during their second and third trimesters has a negative impact on both the mother and her child. Compared with pregnant women in urban areas, rural pregnant women who are in more disadvantaged situation may have more serious psychological problems. Particular, many rural pregnant women had internal migrant work experience during pregnancy in rural China. It is thus necessary to study the prevalence of depressive symptoms and correlated factors among Chinese northwest rural pregnant women. Methods This study was conducted from October 2017 to April 2018 and surveyed 1053 pregnant women in the middle and late stages of pregnancy who were registered in rural areas, gave informed consent and did not suffer from cognitive impairment or severe mental illness. Depressive symptoms were evaluated by the Chinese Version of the Short Depression Anxiety and Stress Scale (DASS-C21). Demographic characteristics, pregnancy characteristics and family factors were obtained through structured questionnaires. This study employed multiple factor logistic regression to analyze the relationship between depressive symptoms and their correlates. Results The prevalence of depressive symptoms among pregnant women during their second and third trimesters was 16.14% (95%CI 13.92%-18.36%). Higher education levels (OR = 0.50; 95%CI 0.29–0.85) and taking folic acid (OR = 0.59; 95%CI 0.39–0.89) reduced the risk of depression symptoms. The family receiving rural welfare (OR = 1.69; 95%CI 1.04–2.75), migration for work (OR = 1.95; 95%CI 1.03–3.71) and living with both parents and parents-in-law (OR = 2.55; 95%CI 1.09–5.96) increased the risk of depressive symptoms. Conclusions The prevalence of depressive symptoms among pregnant women during their second and third trimesters in Northwest rural China was 16.14% that was nearly 4 percentage points higher than the average survey result of the pregnant women in developed countries and was higher than the findings in Chinese urban areas. To prevent depression symptoms, it’s essential to early screen and provide folic acid for free when antenatal examination. Moreover, maternal examination files should be established so that wo pay attention to the psychological status of pregnant women who were with low education levels, poor family economic situations, excessive parental burden and who had been migrant workers.
