Prevalence and Associated Factors of Antenatal Depressive Symptoms in Pregnant Women Living in an Urban Area of Thailand

BACKGROUND: Depression is a major public health problem in middle- and low-income countries. Depression in pregnancy has adverse effects on obstetric outcomes. Maternal depression remains under-recognized, under-diagnosed and undertreated in Thailand. Antenatal screening of depression is an important strategy to improve maternal and neonatal outcomes. This problem has rarely been investigated in Thailand, especially in urban areas. OBJECTIVE: To discover the prevalence, associated factors, and predictive factors of depression in pregnant women living in an urban area. MATERIALS AND METHODS: This cross-sectional study of 402 pregnant women was conducted during antenatal care at the Department of Obstetrics and Gynecology, Faculty of Medicine Vajira Hospital, Navamindradhiraj University, Bangkok, Thailand, from 10 September to 31 November 2019. The participants were interviewed using a structured questionnaire that included a demographic profile, obstetric conditions, socio-cultural characteristics, and a Thai language version of the Center for Epidemiologic Studies-Depression Scale to assess depressive symptoms. RESULTS: Among a total 402 pregnant women, the prevalence of depressive symptoms in pregnant women in an urban area was 18.9%. Depressive symptoms in pregnant women were significantly associated with divorce (p < 0.001), low family income (p < 0.03), financial insufficiency (p < 0.001), extended family (p < 0.001), history of previous abortion (p = 0.033), history of previous pregnancy complications (p = 0.044), current alcohol use (p = 0.03), current tobacco use (p = 0.009), current substance abuse (p = 0.002), marital conflict (p < 0.001), and family conflict (p < 0.001). The significant factors predicting depression in pregnant women were extended family (AOR 3.0, 95% CI 1.59–5.51, p=0.001) and marital conflict (AOR 4.7, 95% CI 2.37–9.11, p<0.001). CONCLUSION: This study revealed that the prevalence of depressive symptoms in pregnant women living in an urban area in Thailand was 18.9%. The significant associated factors of depressive symptoms were divorce, low family income, financial insufficiency, extended family, previous abortion, previous pregnancy complications, current alcohol use, current tobacco use, current substance abuse, marital conflict, and family conflict. Extended family and marital conflict were significant predictive factors for antenatal depressive symptoms.
