Summary of maternal and fetal participant characteristics, correlations between BMI and potential confound variables. Maternal physical and mental health were measured using self-report rating scales. The adapted Health Practices Scale consists of 53 items on which participants rank from 1 = never to 6 = always the frequency of engaging in health behaviors (e.g., Have blood pressure checked regularly). The State-Trait Anxiety Inventory (STAI) consists of two 20-item subscales measuring current and longstanding anxiety. Per subscale, scores indicate ‘no or low anxiety’ (20–37), ‘moderate anxiety’ (37–44), and ‘high anxiety’ (45–80). The Center for Epidemiological Studies-Depression scale (CES-D) consists of 20 items on which participants rank their experience of depression symptoms during the past week. Scores above 16 indicate clinically significant depression symptoms.
