To determine if an anxiety dimension in the Edinburgh Postnatal Depression Scale (EPDS) could be identified in a sample of pregnant women with high social risk factors.
Four hundred women attending prenatal outreach programs, most of whom were single, low-income, and Aboriginal, participated in a study of feelings in pregnancy. The primary outcome measure was the EPDS. Data were also collected on sociodemographic, obstetrical-biological, psychological, and behavioural variables.
Factor analysis of the EPDS revealed 3 factors: anxiety, depression, and self-harm. The anxiety factor accounted for the greatest variance in the overall EPDS score. Comparisons of different groups of women revealed significantly more anxiety in the women aged under 19 years, compared with those over 25 years (P < 0.01). Linear regression analysis showed anxiety was associated with age, stressors (that is, pregnancy, health of the baby, birth of the baby, money, and other), history of depression, and fluctuating moods.
Anxiety symptoms were predominant in the emotional distress identified by the EPDS in this sample of socially high-risk pregnant women. Younger women appear to experience the highest levels of anxiety. Anxiety in pregnancy in socially high-risk women should not be normalized.
确定在具有高社会风险因素的孕妇样本中，能否识别出爱丁堡产后抑郁量表（EPDS）中的焦虑维度。
400名参加产前外展项目的女性参与了一项关于孕期感受的研究，其中大多数为单身、低收入的原住民女性。主要结局指标是EPDS。还收集了社会人口学、产科生物学、心理和行为变量的数据。
对EPDS进行因子分析发现了3个因子：焦虑、抑郁和自我伤害。焦虑因子在EPDS总分中占最大方差。不同组女性的比较显示，19岁以下女性的焦虑明显多于25岁以上女性（P<0.01）。线性回归分析表明，焦虑与年龄、压力源（即怀孕、婴儿健康、婴儿出生、金钱及其他）、抑郁史和情绪波动有关。
在这个社会高风险孕妇样本中，EPDS识别出的情绪困扰中，焦虑症状最为突出。年轻女性似乎焦虑水平最高。社会高风险女性孕期的焦虑不应被视为正常现象。
