dc.description.abstract | Background Worldwide, two million babies are stillborn every year. While the majority of stillbirths occur in low and middle-income countries, stillbirth is still one of the most common adverse pregnancy outcomes in high-income countries. In Ireland, the latest National Perinatal Mortality Clinical Audit report states a stillbirth rate of 4.20 per 1000 births for the year 2020, showing an increase compared to previous years. The belief that reduced stillbirth rates in high-income countries cannot be achieved is refuted by differences in stillbirth rates across different countries. Although not all stillbirths are preventable, there has been a call made in high-income countries to focus on risk factors for stillbirth, in order to reduce stillbirth rates. These risk factors include sociodemographic factors, medical factors, obstetric history-related factors, placental and fetal-related factors as well as behavioural and lifestyle-related factors. Some of these factors are modifiable through medical management or through behaviour change modification. This Thesis focuses on risk factors that have the potential to be modified through maternal behaviour change interventions: substance use (smoking, alcohol, and illicit drug use), high BMI, sleep position, and attendance at antenatal care. Strategies have been successfully implemented internationally to reduce stillbirth rates by designing and implementing care bundles that, amongst other elements, take into consideration the modifiable/behavioural risk factors for stillbirth. However, in Ireland, no such initiatives have been developed, although recommendations have been made that support their development. For behaviour change interventions or public health initiatives to have the best possible success in reducing the rates of stillbirth, they need to be designed with a solid evidence base. Hence, the overall objective of this Thesis was to build the evidence base to enhance the understanding of the modifiable behavioural risk factors for stillbirth and pregnancy. Further, this evidence base is needed to inform the future development of a behaviour change intervention that could be part of a care bundle with the objective of reducing stillbirth rates in Ireland. Methodology To address the Thesis´s aims, both qualitative and quantitative methods were utilised. Applying multiple methods to explore a phenomenon provides flexibility to analyse different aspects of it in the different studies. Initially, a non-systematic review of the literature was conducted to identify the target behavioural risk factors that this project was going to focus on (Chapter 2). A website quantitative content analysis was conducted to assess the availability of information related to stillbirth and behavioural risk factors for stillbirth in Irish and UK websites (Chapter 3). For this study, descriptive and inferential statistics were utilised. Further, three systematic qualitative meta-synthesis were conducted to identify facilitators and barriers to modify identified behavioural risk factors according to the pregnant women’s experience (Chapters 4-6). A meta-ethnographic approach as described by Noblit and Hare was adopted to conduct these qualitative meta-syntheses. Reflexive Thematic Analysis as described by Braun and Clarke, with a constructivist approach, was used to conduct a qualitative semi-structured interview study with postpartum women about their experiences of stillbirth information provision and behaviour change during their antenatal care (Chapter 7). Finally, a systematic review of interventions designed in the context of stillbirth prevention that targeted behavioural risk factors was conducted (Chapter 8). This systematic review had the objective of identifying which behaviour change techniques (BCTs) have been used to date. Results The findings of the literature review (Chapter 2) showed that the modifiable behavioural risk factors with the strongest evidence of associations with stillbirth were substance use, smoking, heavy drinking and illicit drug use, lack of attendance and compliance with antenatal care, weight-related risks, and sleep position. The quantitative content analysis of websites (Chapter 3) revealed that information about stillbirth and behavioural risk factors for stillbirths was scarce on websites directed at the pregnant population, with only one website containing all the information sought. Five main areas of concern were identified across the three meta-synthesis of qualitative research of facilitators and barriers influencing women’s prenatal health behaviours (Chapters 4-6), regardless of the behaviour explored: 1) health literacy, awareness of risks and benefits; 2) insufficient and overwhelming sources of information; 3) lack of opportunities and healthcare professionals attitudes interfering with communication & discussion; 4) social influence of environment, and 5) social judgement, stigmatisation of women and silence around stillbirth. Further, the qualitative study with postpartum women (Chapter 7) revealed that women perceived behaviour change during pregnancy as easy and natural, as they were focused on obtaining the best outcomes for their babies. Although women had high levels of awareness regarding health advice, their awareness about stillbirth was very limited. Women reported a lack of discussion about stillbirth and behavioural risk factors during their antenatal care; however, most women showed a positive disposition towards receiving this information because “knowledge is key”, as long as it is done in a “sensible manner”. The systematic review of interventions designed in the context of stillbirth prevention identified nine relevant interventions. From the BCT coding, it was established that the most common BCT used was “information about health consequences”, followed by “adding objects to the environment” (Chapter 8). Conclusion This research makes a valuable contribution to the understanding of the maternal behaviours associated with an increased risk of stillbirth, and it provides a necessary evidence-base to inform future prevention strategies to reduce rates of stillbirth in Ireland and in similar healthcare settings. This research sought to incorporate women’s voices and use research methods to produce high-quality results that meet the research objectives. The findings from the studies in this Thesis support four overarching topics and highlight issues related to 1) health literacy and sources of information, 2) relationships with healthcare professionals (HCPs), 3) healthcare systems and structural barriers, and 4) interpersonal, social and structural factors. In response to the research findings, several recommendations are made in relation to policy, practice and research which are grounded on women’s experiences during pregnancy. Regarding policy, these recommendations include improving education and information sources for women and HCPs, providing pregnancy-specific supports, utilising community services to support women with behaviour change, and developing a care bundle to tackle the behavioural risk factors for stillbirth. Furthermore, the work practice recommendations made include developing clinical guidelines to support HCPs in providing care to pregnant women, and prioritising health promotion during antenatal care. These priorities might also serve to help funders and researchers to design and conduct policy-relevant research. The key future research areas identified by this Thesis are in relation to the involvement of PPI representatives, the assessment of the quality of the available sources of information and the further exploration of potential facilitators and barriers to modifying pregnant women’s sleeping position from a qualitative perspective. In addition, this Thesis proposes a detailed process to continue building on the work set out in the different studies to develop a pregnancy-specific behaviour change intervention for the modifiable behavioural risk factors for stillbirth in the future. | en |
