Depression and its risk factors among pregnant women in 2008 Sichuan earthquake area and non-earthquake struck area in China

Abstract

BackgroundOn May 12, 2008, a powerful 8.0 magnitude earthquake struck China's Sichuan province. While some studies have assessed the mental and physical wellbeing of disaster victims, few have examined the long-term impact of natural disasters on pregnant women's mental health. As such, this study aims to assess whether the Sichuan earthquake continues to negatively affect women's mental health, 4 years since its occurrence. In addition, predictive and protective risk factors of depressive symptoms among pregnant women were also identified. MethodsFrom June 2012 to October 2012, 520 pregnant women were interviewed, of whom 253 were from an earthquake struck area and 267 were from a non-earthquake struck area. Symptoms of antenatal depression were measured using the Edinburgh Postnatal Depression Scale (EPDS) with a cutoff of≥10. ResultsThe prevalence rate of depression among pregnant women in the earthquake area was 34.5% (95% CI, 28.9–40.6), while the rate in the non-earthquake area was 39.6% (95% CI, 33.9–45.5). The perceived stresses associated with pregnancy and social support from husbands are significantly correlated with antenatal depression. Limitations: Lack of diagnosis for antenatal depression and it is a self-report evaluation. ConclusionsThis study found that the Sichuan earthquake does not necessarily have a long-lasting effect on pregnant women who were once victims of the disaster. It was found that pregnant women who experience high levels of pressures from the pregnancy and receive medium support from husbands are more susceptible to experience antenatal depression than pregnant women who perceive higher levels of support from husbands.
