The COVID-19 pandemic affected daily life routines and lifestyles of pregnant and postpartum women and increased their stress and risk of suffering from mental health problems. The aim of this study was to analyse which sociodemographic variables, COVID-19 exposure variables and lifestyles to cope with stress variables predicted anxiety, depression, and PTSD symptoms in pregnant and postpartum women during the COVID-19 pandemic. A cross-sectional design was performed with a sample of 3356 Spanish women participating in the Riseup-PPD-COVID-19 study. These participants completed an online survey composed of measures of anxiety (GAD-7), depression (EPDS), and PTSD related to COVID-19 (Checklist DSM-5), as well as demographics, exposure to COVID-19, and lifestyles to cope with stress. Regarding results, 47.2% showed depression and a third reported anxiety, whereas moderate scores were observed in PTSD symptoms. The most commonly used strategies to cope with stress in the COVID-19 pandemic were talking with friends and family and increasing time with social networks. Better results in mental health were associated with coping strategies such as talking with family and friends or participating in family activities, physical activity, sleeping well at night, eating healthier, and increasing personal care. Furthermore, poor results in mental health were observed in those participants who increased time with screens, ate fast food, reported substance use, and talked more frequently with health professionals. More symptoms were also observed in younger women, primiparous women, and those who reported more exposure to COVID-19. The results underline the need to strengthen the mental health of pregnant and postpartum women. Trial registration: ClinicalTrials.gov Identifier: NCT04595123.

COVID-19 大流行影响了孕妇和产后妇女的日常生活和生活方式，增加了她们的压力和患心理健康问题的风险。本研究的目的是分析哪些社会人口统计学变量、COVID-19 暴露变量和应对压力变量的生活方式可以预测 COVID-19 大流行期间孕妇和产后妇女的焦虑、抑郁和 PTSD 症状。对参与 Riseup-PPD-COVID-19 研究的 3356 名西班牙女性样本进行了横断面设计。这些参与者完成了一项在线调查，其中包括与 COVID-19 相关的焦虑 (GAD-7)、抑郁 (EPDS) 和 PTSD（清单 DSM-5），以及人口统计数据、与 COVID-19 的接触情况以及生活方式。应对压力。关于结果，47.2% 的人表现出抑郁，三分之一的人报告焦虑，而 PTSD 症状的得分中等。在 COVID-19 大流行期间，应对压力最常用的策略是与朋友和家人交谈以及增加使用社交网络的时间。心理健康的更好结果与应对策略有关，例如与家人和朋友交谈或参加家庭活动、体育活动、晚上睡得好、饮食更健康以及加强个人护理。此外，那些增加看屏幕时间、吃快餐、报告药物使用情况以及更频繁地与健康专业人员交谈的参与者的心理健康结果也很差。在年轻女性、初产女性和报告更多接触 COVID-19 的女性中也观察到了更多症状。研究结果强调需要加强孕妇和产后妇女的心理健康。试验注册：临床试验。政府标识符：NCT04595123。
