Population-Based Placental Weight Ratio Distributions And Determinants Of Placental Weight Ratios, Erin M. Macdonald
Population-Based Placental Weight Ratio Distributions And Determinants Of Placental Weight Ratios, Erin M. Macdonald
Electronic Thesis and Dissertation Repository
The placental weight ratio (PWR) is a common proxy for the balance between fetal and placental growth, and is defined as the placental weight over the birth weight. The objectives were (1a) to establish PWR distributions by gestational age for the overall population and (1b) for small, average and large for gestational age infants (SGA, AGA, LGA) and (2) to determine what pregnancy related conditions were associated with the PWR. The data were obtained using a hospital based retrospective cohort. Nonparametric quantile regression was used for the first and multinomial logistic regression for the second objective. The results show how …
Physical Activity Among Latino Children In London, Ontario: An Assessment Of Physical Activity Levels, Sedentary Behaviours, And Physical Activity-Related Barriers And Facilitators, Gillian E. Mandich
Physical Activity Among Latino Children In London, Ontario: An Assessment Of Physical Activity Levels, Sedentary Behaviours, And Physical Activity-Related Barriers And Facilitators, Gillian E. Mandich
Electronic Thesis and Dissertation Repository
The purpose of the study was to assess the physical activity (PA) levels, sedentary behaviours, and PA-related barriers and facilitators of a sample of Latino children in London, Canada. Forty boys and 34 girls (mean age = 11.4 years) completed questionnaires related to PA levels, sedentary behaviours, and PA-related barriers and facilitators, and 64 of these children wore an accelerometer for 4 consecutive days. Children spent an average of 53 minutes per day in moderate-to-vigorous PA. The average daily sedentary time for participants was 8.6 hours, and subjective measures revealed that participants spent 3.8 hours per day in front of …
Fetal Growth Restriction: Molecular Mechanisms And Long-Term Outcomes, Caroline D. Albion
Fetal Growth Restriction: Molecular Mechanisms And Long-Term Outcomes, Caroline D. Albion
Electronic Thesis and Dissertation Repository
Fetal undernutrition is a major factor in the pathophysiology of fetal growth restriction (FGR) in many species, including humans. Our hypothesis is that mild maternal nutrient restriction (MNR) in a mouse provides a clinically relevant model to study FGR mechanisms and long-term effects similar to humans and the developmental origins of health and disease (DOHaD) predisposition. A MNR mouse model of FGR was developed by feeding mothers 70% normal daily caloric intake during E6.5 to E18.5 gestation. Significant reduction in fetal weight and fetal liver and lung weights with less impact on brain weight resulted, similar to asymmetric human FGR. …
Depressive Symptoms In Mothers Of Children With New-Onset Epilepsy: A Prospective Study, Mark Anthony Ferro
Depressive Symptoms In Mothers Of Children With New-Onset Epilepsy: A Prospective Study, Mark Anthony Ferro
Electronic Thesis and Dissertation Repository
Having a child diagnosed with a chronic illness such as epilepsy is a major source of stress for caregivers. Up to half of mothers of children with epilepsy are at increased risk for clinical depression and symptoms of maternal depression are associated with poorer health outcomes in these children. The purpose of this study was to: 1) estimate the prevalence and course of depressive symptoms over 24 months among mothers of children with new-onset epilepsy; 2) identify subgroups of mothers that share similar trajectories of depressive symptoms; and, 3) assess the family factors involved in the causal pathway between maternal …
