All Our Babies Cohort Study: recruitment of a cohort to predict women at risk of preterm birth through the examination of gene expression profiles and the environment
<p>Abstract</p> <p>Background</p> <p>Preterm birth is the leading cause of perinatal morbidity and mortality. Risk factors for preterm birth include a personal or familial history of preterm delivery, ethnicity and low socioeconomic status yet the ability to predict preterm delivery before the onset of preterm labour evades clinical practice. Evidence suggests that genetics may play a role in the multi-factorial pathophysiology of preterm birth. The All Our Babies Study is an on-going community based longitudinal cohort study that was designed to establish a cohort of women to investigate how a women's genetics and environment contribute to the pathophysiology of preterm birth. Specifically this study will examine the predictive potential of maternal leukocytes for predicting preterm birth in non-labouring women through the examination of gene expression profiles and gene-environment interactions.</p> <p>Methods/Design</p> <p>Collaborations have been established between clinical lab services, the provincial health service provider and researchers to create an interdisciplinary study design for the All Our Babies Study. A birth cohort of 2000 women has been established to address this research question. Women provide informed consent for blood sample collection, linkage to medical records and complete questionnaires related to prenatal health, service utilization, social support, emotional and physical health, demographics, and breast and infant feeding. Maternal blood samples are collected in PAXgeneâą RNA tubes between 18-22 and 28-32 weeks gestation for transcriptomic analyses.</p> <p>Discussion</p> <p>The All Our Babies Study is an example of how investment in clinical-academic-community partnerships can improve research efficiency and accelerate the recruitment and data collection phases of a study. Establishing these partnerships during the study design phase and maintaining these relationships through the duration of the study provides the unique opportunity to investigate the multi-causal factors of preterm birth. The overall All Our Babies Study results can potentially lead to healthier pregnancies, mothers, infants and children.</p
Cohort Profile: The All Our Babies pregnancy cohort (AOB)
Cohort ProfileWhy was the cohort set up? All Our Babies (AOB) is a community-based, longitudinal pregnancy cohort developed to investigate the relationships between the prenatal and early life periods and outcomes for infants, children and mothers. The design of AOB follows a life course perspective, whereby the influence of early events on long-term health and development of both mothers and children are investigated through examining factors across life stages. AOB spans pregnancy, birth and early postpartum through childhood, and therefore provides the unique opportunity to describe the relations between prenatal events and early life development and to examine key factors that influence child and mother well-being over time. AOB was originally designed to measure maternal and infant outcomes during the perinatal period, with a particular emphasis on barriers and facilitators to accessing health care services in Calgary, Alberta. Approximately 1 year after recruitment had started, an additional objective,to examine biological and environmental determinants of adverse birth outcomes, specifically spontaneous pre-term birth, was added. Recognition of the opportunity to continue to collect relevant life course information on the AOB families, collaborations with content experts and securing additional funding has enabled ongoing follow-up of AOB mother-child dyads. The overall objective was to further investigate risk and protective factors for optimal child development, and to understand the trajectory and impact of poor maternal mental health over time. Mothers have completed questionnaires from pregnancy to 3 years postpartum, and consented to providing the research team with access to their obstetric medical records. Data collection for a 5-year follow-up questionnaire is ongoing. A subgroup within the cohort participated in the âprediction of preterm birthâ component and provided blood samples during pregnancy and an umbilical cord blood sample. The continuation of follow-up to 8 years is under way.Alberta Innovates - Research Gran
Gauging knowledge of developmental milestones among Albertan adults: a cross-sectional survey
<p>Abstract</p> <p>Background</p> <p>Parental knowledge of child development has been associated with more effective parenting strategies and better child outcomes. However, little is known about what adults who interact with children under the age of 14 years know about child development.</p> <p>Methods</p> <p>Between September 2007 and March 2008, computer assisted telephone interviews were completed with 1443 randomly selected adults. Adults were eligible if they had interacted with a child less than 14 years of age in the past six months and lived in Alberta, Canada.</p> <p>Results</p> <p>Sixty three percent of respondents answered two (or more) out of four questions on physical development correctly. Fifteen percent of respondents answered two (or more) out of three questions on cognitive development correctly. Seven percent of respondents answered three (or more) out of five questions on social development correctly. Two percent of respondents answered three (or more) out of five questions on emotional development correctly. Parents and females were better able to identify physical developmental milestones compared to non-parents and males. 81% of adults correctly responded that a child's experience in the first year of life has an important impact on later school performance, 70% correctly responded that a child's ability to learn is not set from birth, 50% of adults correctly responded that children learn more from hearing someone speak than from television, and 45% recognized that parents' emotional closeness with a baby influences later achievement. Parents were most likely to use doctors/paediatricians, books, and nurses as resources. Among parents, there was no relationship between knowledge and parenting morale.</p> <p>Conclusions</p> <p>The majority of adults were unable to correctly answer questions related to when children under six years of age typically achieve developmental milestones. Knowledge of physical development exceeded knowledge about cognitive, emotional and social development. Adults were aware of the importance of positive experiences in influencing children's development. Strategies to improve awareness of developmental milestones combined with information on how to support optimal development may improve child development outcomes. Given that parents seek information about child development from health care providers there is an opportunity to ensure that providers are well informed about child development.</p
