|Pregnancy Stress Coping Health Behaviors|
Health behaviors are important modifiable factors for promoting maternal-infant health during pregnancy, and include behaviors such as diet, exercise, and avoidance of harmful substances. During pregnancy, women are often motivated to improve their lifestyle to achieve positive pregnancy outcomes; however, they may struggle to do so because certain behaviors such as excessive eating, smoking and drinking have become a means for coping with stress. Stress prior to and during pregnancy negatively impacts birth outcomes via complex behavioral and physiologic pathways. From a behavioral perspective, stress diminishes women's engagement in positive health behaviors during pregnancy. From a physiologic perspective, stress affects the regulation of cortisol, a hormone involved in fetal development and timing of delivery. Women use various coping styles to manage stress. It is unknown, however, whether certain coping styles attenuate the negative behavioral and physiologic effects of stress on birth outcomes. Therefore, the purpose of this descriptive, cross-sectional study is to examine the influence of coping styles on stress, physiologic cortisol regulation and health behaviors in a diverse sample of pregnant women (N=55) during 24-28 weeks gestation.
A quantitative design with a qualitative arm will be used to:
- explain the relationship between cortisol regulation and lifetime stress,
- determine whether coping styles (active vs. disengaged) moderate the effect of stress on cortisol, health behaviors, and birth outcomes, and
- describe women's qualitative experience of stress and coping and determine the extent to which the qualitative findings converge with the quantitative findings.
Data will be collected over three prenatal visits during the second half of pregnancy, and will include self-report questionnaires, multiple salivary cortisol sampling, medical record data, a structured stress interview and a semi-structured qualitative interview in a subset of participants (n=12). This study will use an interview-based stress assessment in tandem with physiologic (i.e. cortisol) stress measures in pregnancy. Additionally, the qualitative data will provide a contextual understanding of pregnant women's stress and coping experiences. The research findings will inform the future development and testing of a psychosocial, coping-based intervention to promote positive health behaviors in pregnancy and birth outcomes. Furthermore, this training will provide a solid scientific foundation for the applicant to develop a career as an independent nurse-scientist in maternal-infant health promotion research, under the guidance of an experienced interdisciplinary team of mentors with complementary expertise in stress, coping health behavior, and pregnancy related research. The proposal is consistent with the National Institute of Nursing Research's (NINR) mission to support research that promotes health and prevents disease across the lifespan, builds the scientific foundation for clinical practice, and invests in the training of the next generation of nurse-scientists.
