Postpartum Symptoms of Depression are Related to Infant Feeding Practices in a National WIC Sample

The role of perinatal maternal symptoms of depression, anxiety and pregnancy-specific anxiety for infant's self-regulation: A prospective longitudinal study

BACKGROUND

Maternal symptoms of anxiety and depression are highly prevalent during pregnancy and postpartum and have the potential to impact fetal development and offspring behavior. However, research on the effects of fetal exposure to maternal subclinical affective symptoms on infant self-regulation is still lacking. Self-regulation provides a fundamental precondition for healthy development and overall life success whereas dysfunctional self-regulation can lead to behavioral problems, poor academic achievement, social rejection, and physical/mental disorders. During pregnancy and infancy, children largely depend upon their mothers in order to successfully regulate their internal states. Given the high prevalence of mothers suffering from anxiety and depressive symptoms during pregnancy and after childbirth, the aim of the present study is to explore how maternal affective symptoms change during the pre- and postnatal period, and how measures obtained in pregnancy and beyond impact self-regulation in infants, as indicated by crying-, sleeping-, and/or feeding problems.

METHODS

This prospective longitudinal study investigates the effects of maternal symptoms of depression, anxiety, and pregnancy-specific anxiety on infant's self-regulation in N = 225 mother-infant dyads. Maternal affective symptoms were examined at five prenatal and three postnatal time-points using the Edinburgh Postnatal Depression Scale (EPDS), the State-Trait Anxiety Inventory (STAI) and the Pregnancy Related Anxiety Questionnaire Revised (PRAQ-R2). Infant's self-regulation was assessed twice - at the age of three and six months - using the Crying Feeding Sleeping Scale (SFS).

RESULTS

Maternal pregnancy-specific anxiety was the most significant predictor for infant self-regulatory problems. It predicted crying-, sleeping, and feeding problems and explained up to 18 % of the variance. Even when controlling for maternal postpartum affective symptoms, pregnancy-specific anxiety remained a significant predictor for infant self-regulation problems.

LIMITATIONS

Rather homogenous sample (high socioeconomic status). Data based on maternal reports of infant behavior.

CONCLUSIONS

Our results suggest that fetal exposure to maternal affective symptoms - specifically pregnancy-related anxiety - plays a substantial role in the development of infant self-regulation problems, potentially mediated by epigenetic modifications. Importantly, even though maternal symptoms of depression and anxiety only reached subclinical levels, they were predictive for infant crying-, sleeping-, and feeding problems. Our findings underline the importance of early prevention and clearly tailored interventions during pregnancy and postpartum to prevent adverse outcome for mother, child and family.

Levels and Determinants of Antenatal Breastfeeding Attitudes among Pregnant Women: A Cross-Sectional Study

Breastfeeding attitudes are strong predictors of breastfeeding behavior. Gaining a deeper understanding on the levels and determinants of antenatal breastfeeding attitudes is crucial. This cross-sectional study involved 124 pregnant women at a tertiary hospital in Hunan, China. A self-administered questionnaire, the Iowa Infant Feeding Attitude Scale, the Edinburgh Postnatal Depression Scale, the Pregnancy Stress Rating Scale, the Childbirth Attitude Questionnaire, the Perceived Social Support Scale, and the Breastfeeding Knowledge Questionnaire were assessed during their first-trimester, second-trimester, and third-trimester hospital visit. Multiple linear regression was conducted to identify the determinants of breastfeeding attitudes. The participants reported neutral (56.39 ± 5.69) levels of breastfeeding attitudes. The determinants of antenatal breastfeeding attitudes were other family members' support for exclusive breastfeeding: moderate (β = 0.278, p < 0.05), depressive symptoms (β = -0.191, p < 0.05), and breastfeeding knowledge (β = 0.434, p < 0.001). The variables explained 33.9% (adjusted R²) of the total variation in breastfeeding attitudes scores (F = 4.507, p < 0.001). Namely, other family members' support for EBF was a negative influence on positive breastfeeding attitudes. The women whose other family members were moderate of EBF had more positive attitudes toward breastfeeding compared to those whose other family members were very supportive of EBF. The depressive symptoms were negatively associated with positive breastfeeding attitudes, and lower levels of depressive symptoms were associated with higher levels of positive breastfeeding attitudes among pregnant women. Additionally, breastfeeding knowledge was positively associated with positive breastfeeding attitudes. The more knowledgeable about breastfeeding, the more positive the attitude towards breastfeeding. Health professionals should identify these modifiable factors that may contribute to poorer breastfeeding attitudes, which is useful in targeting promotions of breastfeeding.
