The effect of stress and anxiety associated with maternal prenatal diagnosis on feto-maternal attachment

Background

A couple's decision to undergo an invasive test based on a screening test result is a process associated with anxiety. The aim of this study was to determine whether anxiety and prenatal attachment were affected by undergoing an invasive test compared to women in early pregnancy and after a reassuring anomaly scan.

Methods

200 women were recruited at booking, 14 women and 20 partners after an invasive test and 81 women following an anomaly scan. A questionnaire was completed using the Beck Anxiety Inventory and Maternal or Paternal Antenatal Attachment Scales.

Results

Women who have had an invasive test have higher levels of anxiety compared to women at booking (P < 0.01) and after an anomaly scan (P = 0.002). Anxiety declines from booking to the time of an anomaly scan (P = 0.025), whilst attachment increases (P < 0.001). There is a positive correlation between anxiety and attachment in women who have had an invasive test (r = 0.479). Partners of women undergoing an invasive test experience lower levels of anxiety (P < 0.05).

Conclusions

Women undergoing prenatal diagnostic procedures experience more psychological distress, which may be currently underestimated. Establishment of interdisciplinary treatment settings where access to psychological support is facilitated may be beneficial.

Exploring Relationships Among Psychosocial Status, Dietary Quality, and Measures of Placental Development During the First Trimester in Low-Income Women

Purpose: To examine the relationships between maternal psychosocial factors and dietary quality and explore the relationships among dietary quality and selected biomarkers of nutrition and placental development. Method: A cross-sectional design in 18 low-income, pregnant women. Results: Partner support was positively related to vegetable intake (r = .54) and negatively related to intake of iron (r = -.68) and grains (r = -.67). Emotional eating in response to anger was negatively related to intake of iron-(r /it> = -.53) and folate-rich (r = -.75) foods, and emotional eating in response to anxiety was negatively related to intake of folate-rich foods (r = -.51). Depressed women had an increased intake of calcium-rich foods (r = .60). Levels of vascular endothelial growth factor (VEGF) were negatively related to depression (r = -.56) and intake of foods high in calcium (r = -.53) and iron (r = -.34) but positively related to serum calcium levels (r = .60). VEGF was negatively relationship to soluble fms-like tyrosine kinase 1 (sFlt-1; r = -.56). Placental growth factor had a negative relationship with maternal serum levels of albumin (r = -.61) and calcium (r = -.65). Conclusions: Low-income pregnant women who eat to cope with anger and anxiety may have an inadequate intake of nutrients that contribute to positive pregnancy outcomes. Placental development in the early weeks of pregnancy may be influenced by maternal psychosocial and nutritional status. More research is needed to explore the relationship of dietary quality and placental development in the first trimester of pregnancy.

A nurse-driven quality improvement program to improve perinatal outcomes

Preterm birth (PTB) is one of the most acute problems in obstetrics today. It is recommended that quality measures related to the prevention and management of PTB be identified and implemented for systems of clinical care. With its professional commitment to women and families, nursing is positioned to play an important role in this professional issue of quality improvement. A nursing team joined forces with a managed care organization to develop and implement a quality program to improve perinatal outcomes for pregnant women enrolled in the managed care organization. The team integrated a holistic framework, the best evidence, their clinical expertise, and the pregnant member's values and concerns. Using a pre/postprogram implementation design, perinatal outcomes in terms of neonatal intensive care length of stay were improved, with resultant cost savings. The improvement of these proxy measures for the health of the infant is an initial step in the reduction of PTB.

Psychological and physiological stress: impact on preterm birth

Stress increases corticotropin-releasing hormone and may ultimately result in increased uterine contractility. Stress also increases cytokine production, which independently may lead to preterm birth or increase susceptibility to infection, thereby increasing the risk of preterm birth. Finally, stress may change health behaviors that lead to preterm birth. Research findings on the relationship between stress and preterm birth have been contradictory. In this article, the authors propose a model of the relationship between stress and preterm birth, evaluate the research on stress and pregnancy outcomes, and discuss the implications for nursing practice and research.

The relationship between abuse, sexually transmitted diseases, & group B streptococcus in childbearing women

PURPOSE

To examine the relationship between abuse, sexually transmitted diseases (STDs) and group B (GBS) infection among childbearing women using Selye's (1978) stress response theory.

DESIGN AND METHODS

Retrospective chart review (n = 205) from two different clinical sites in Washington State, using the Childbearing Health Questionnaire to guide data collection. The women in the sample had an average age of 26.4 years and represented Anglo (81.4%), Hispanic (12%), Native American (3.9%), and African American (2.5%) ethnic groups. Thirty-eight percent ( = 78) reported experiencing physical and/or sexual abuse during their lifetimes and 31% had been diagnosed with an STD.

RESULTS

Abuse was significantly related to STDs, and ethnicity emerged as a significant variable for the Hispanic women participating in this study. Findings indicated that infection with group B was also related to abuse status ( r=.60, p < or =.002) and to presence of herpes simplex virus-2 (r =.468, p<or =.01). Total prevalence of STDs was positively related to abuse ( r=.78, p <or =.000). Abused Hispanic women were more likely to be positive for STDs than were their nonabused counterparts ( p <or =.03).

CLINICAL IMPLICATIONS

The findings support previously published results that abuse is widespread in the United States and that abused women are at increased risk for STDs. These results highlight the need for regular screenings for abuse during healthcare, for abuse is a critical variable to consider when screening for STDs and GBS. STD screening typically occurs during the first prenatal visit and may need to be repeated for high-risk groups.
