Incidence and influencing factors of postpartum depression and anxiety among 2 490 puerpera in Urumqi in 2020

Objective To investigate the incidence and influencing factors of postpartum depression and anxiety in Urumqi during the coronavirus disease （COVID-19） epidemic period in 2020.

Methods Research subjects were the parturients who underwent postpartum health checkups in a third class hospital in Urumqi from January 2020 to December 2020. The maternal socio demographic and obstetric information were collected， and PHQ-9 and GAD-7 scales were used for screening of PPD and PPA. Calcaneal bone mineral density of the parturients was measured by French Pegasus ultrasonic bone densitometer. After univariate analysis of the related influencing factors of PPD and PPA， multivariate binary logistic regression analysis was used to explore the relationship between mental disorders and various influencing factors.

Results A total of 2 490 puerpera participated in the survey. The incidences of PPD and PPA in 2020 were 13.4 % and 10.8 %， respectively. Six factors with statistical differences after univariate analysis were included in multivariate binary logistic regression analysis. The final results suggested that age over 35 （OR=1.707，95%CI：1.142‒2.551）， unemployment （OR=1.478，95%CI：1.003‒2.205）， multipara （OR=1.340，95%CI：1.037‒1.733）， bone loss and osteoporosis （OR=1.434，95%CI： 1.076‒1.910） were the risk factors of PPD， while breastfeeding （OR=0.466，95%CI： 0.301‒0.721） was a protective factor. Ages between 18‒24 （OR=1.559，95%CI：1.282‒3.097） and cesarean section （OR=1.433，95%CI： 1.105‒1.859） were the risk factors of PPA， while ages between 30‒34 years old （OR=0.524，95%CI： 0.332‒0.827）， occupation as medical staff （OR=0.282，95%CI： 0.807‒0.919）， breastfeeding （OR=0.530，95%CI： 0.330‒0.850） were protective factors.

Conclusion Incidences of PPD and PPA are in middle-low levels during COVID-19 epidemic period. Age， occupation， delivery mode， delivery times， feeding pattern and bone mineral density are the influencing factors. Screen coverage of PPD and PPA in special period should be strengthened， and measures should be taken to reduce the risk.
