Project description:ObjectivesEvaluate the accuracy of the Breast Cancer Risk Assessment Tool (BCRAT), International Breast Cancer Intervention Study risk evaluation tool (IBIS), Polygenic Risk Scores (PRS) and combined scores (BCRAT+PRS and IBIS +PRS) to predict the occurrence of invasive breast cancers at 5 years in a French-Canadian population.DesignPopulation-based cohort study.SettingWe used the population-based cohort CARTaGENE, composed of 43 037 Quebec residents aged between 40 and 69 years and broadly representative of the population recorded on the Quebec administrative health insurance registries.Participants10 200 women recruited in 2009-2010 were included for validating BCRAT and IBIS and 4555 with genetic information for validating the PRS and combined scores.Outcome measuresWe computed the absolute risks of breast cancer at 5 years using BCRAT, IBIS, four published PRS and combined models. We reported the overall calibration performance, goodness-of-fit test and discriminatory accuracy.Results131 (1.28%) women developed a breast cancer at 5 years for validating BCRAT and IBIS and 58 (1.27%) for validating PRS and combined scores. Median follow-up was 5 years. BCRAT and IBIS had an overall expected-to-observed ratio of 1.01 (0.85-1.19) and 1.02 (0.86-1.21) but with significant differences when partitioning by risk groups (p<0.05). IBIS' c-index was significantly higher than BCRAT (63.42 (59.35-67.49) vs 58.63 (54.05-63.21), p=0.013). PRS scores had a global calibration around 0.82, with a CI including one, and non-significant goodness-of-fit tests. PRS' c-indexes were non-significantly higher than BCRAT and IBIS, the highest being 64.43 (58.23-70.63). Combined models did not improve the results.ConclusionsIn this French-Canadian population-based cohort, BCRAT and IBIS have good mean calibration that could be improved for risk subgroups, and modest discriminatory accuracy. Despite this modest discriminatory power, these tools can be of interest for primary care physicians for delivering a personalised message to their high-risk patients, regarding screening and lifestyle counselling.

Project description:Burnout in kindergarten teachers is influenced by individual factors, social factors, and organizational factors. Kindergarten organizational climate as an external work resource may cause teacher burnout when it cannot meet their work demands. To explore the mechanisms that underlie the effects of kindergarten organizational climate on teacher burnout, we investigated the mediating effect of work-family conflict (i.e., work interfering with family and family interfering with work) on the relationship between kindergarten organizational climate and teacher burnout. The study sample included 436 kindergarten teachers in Henan, China. The Chinese versions of the Kindergarten Organizational Climate Scale, Kindergarten Teachers Work-Family Conflict Scale, and Kindergarten Teachers Burnout Scale were applied. The results showed that kindergarten organizational climate was positively correlated with work-family conflict and teacher burnout. Work-family conflict was positively correlated with teacher burnout. Work-family conflict partially mediated the effects of kindergarten organizational climate on teacher burnout. The mediating effect of family interfering with work was significantly stronger than the mediating effect of work interfering with family. The results are discussed with respect to the general literature on the correlation between organizational climate, WFC, and burnout.

Project description:BackgroundFew epidemiological studies of air pollution have used residential histories to develop long-term retrospective exposure estimates for multiple ambient air pollutants and vehicle and industrial emissions. We present such an exposure assessment for a Canadian population-based lung cancer case-control study of 8353 individuals using self-reported residential histories from 1975 to 1994. We also examine the implications of disregarding and/or improperly accounting for residential mobility in long-term exposure assessments.MethodsNational spatial surfaces of ambient air pollution were compiled from recent satellite-based estimates (for PM2.5 and NO2) and a chemical transport model (for O3). The surfaces were adjusted with historical annual air pollution monitoring data, using either spatiotemporal interpolation or linear regression. Model evaluation was conducted using an independent ten percent subset of monitoring data per year. Proximity to major roads, incorporating a temporal weighting factor based on Canadian mobile-source emission estimates, was used to estimate exposure to vehicle emissions. A comprehensive inventory of geocoded industries was used to estimate proximity to major and minor industrial emissions.ResultsCalibration of the national PM2.5 surface using annual spatiotemporal interpolation predicted historical PM2.5 measurement data best (R2 = 0.51), while linear regression incorporating the national surfaces, a time-trend and population density best predicted historical concentrations of NO2 (R2 = 0.38) and O3 (R2 = 0.56). Applying the models to study participants residential histories between 1975 and 1994 resulted in mean PM2.5, NO2 and O3 exposures of 11.3 ?g/m3 (SD = 2.6), 17.7 ppb (4.1), and 26.4 ppb (3.4) respectively. On average, individuals lived within 300 m of a highway for 2.9 years (15% of exposure-years) and within 3 km of a major industrial emitter for 6.4 years (32% of exposure-years). Approximately 50% of individuals were classified into a different PM2.5, NO2 and O3 exposure quintile when using study entry postal codes and spatial pollution surfaces, in comparison to exposures derived from residential histories and spatiotemporal air pollution models. Recall bias was also present for self-reported residential histories prior to 1975, with cases recalling older residences more often than controls.ConclusionsWe demonstrate a flexible exposure assessment approach for estimating historical air pollution concentrations over large geographical areas and time-periods. In addition, we highlight the importance of including residential histories in long-term exposure assessments. For submission to: Environmental Health.

Project description:PURPOSE:Reactive depression and anxiety are common after major life changes such as brachial plexus injuries (BPI). The purpose of this study was to evaluate the incidence and risk factors for coded depression and coded anxiety among patients with BPI using a national database of commercial insurance claims. METHODS:We used the Truven MarketScan database from 2007 to 2013 to identify commercially insured patients aged 18 to 64 years who underwent BPI surgery. For comparison, a control group without BPI was frequency-matched 10:1 by age group, sex, number of provider visits, and length of insurance enrollment. Using International Classification of Diseases, Ninth Revision diagnosis codes and pharmacy claims, we identified coded depression and coded anxiety in the 12 months before and 12 months after BPI surgery. Multivariable Cox regression models were used to determine risk factors for coded depression or coded anxiety, adjusting for known risk factors for depression or anxiety (eg, alcohol, substance abuse). RESULTS:We identified 1,843 patients with BPI and 18,430 controls. Within the 12 months preceding surgery, coded depression and coded anxiety were present in 38% and 42%, respectively, of the BPI group; both were present in 25% and either was present in 54%. The rate of new-onset/postoperatively coded depression among patients with BPI was 142.1/1,000 person-years (12%) and of new-onset/postoperatively coded anxiety was 273.6/1,000 person-years (20%). Patients with BPI were significantly more likely than controls to develop new-onset/postoperatively coded depression (hazard ratio = 1.3; confidence interval [CI], 1.1-1.5) and new-onset/postoperatively coded anxiety (HR = 2.1 [CI, 1.8-2.4]). CONCLUSIONS:Patients undergoing BPI surgery have a high prevalence of coded depression and coded anxiety in the 12 months before surgery and are at higher risk for developing new-onset/postoperatively coded depression and coded anxiety within 1 year after surgery. These findings can be used by BPI surgeons to inform perioperative counseling, guide emotional recovery from injury, and facilitate coordinated or colocated care with mental health professionals. TYPE OF STUDY/LEVEL OF EVIDENCE:Prognostic II.

Project description:Elementary school teachers' math anxiety has been found to play a role in their students' math achievement. The current study addresses the role of teacher math anxiety on ninth-grade students' math achievement and the mediating factors underlying this relationship. Using data from the National Mindset Study, we find that higher teacher math anxiety is associated with lower math achievement. This relationship is partially mediated by the students' perception that their teacher believes not everyone can be good at math and is not explainable by teachers' usable knowledge to teach mathematics. In subsequent analyses, we find that higher teacher math anxiety relates to a reduction in process-oriented (as opposed to ability-oriented) teaching practices, which in turn predict students' perception of teacher mindset. We argue that math anxious teachers and their use of particular teaching strategies have the potential to shape students' math achievement and their perceptions of what their teacher believes about math.

Project description:The prevalence of Fetal Alcohol Spectrum Disorder (FASD) may be underestimated as it can be difficult to diagnose in early childhood possibly reflecting unique developmental trajectories relative to other Neurodevelopmental Disabilities (NDDs). Using data collected via the Early Development Instrument (EDI) between 2010 and 2015, we examined the prevalence of kindergarten children with FASD and their concurrent developmental outcomes. We found that the prevalence of FASD ranged from 0.01 to 0.31%. A greater percentage of children with FASD had teacher-reported home problems that interfered with their classroom functioning. Overall children with FASD had higher mean scores on the developmental domains compared to children with NDDs. Results of the current study can inform strategies and policies for early identification and intervention.

Project description:The fetal environment has been increasingly implicated in later psychological health, but the role of lipids is unknown. Drawing on the ethnically diverse Born in Bradford (BiB) birth cohort, the current study related levels of high-density lipoprotein (HDL), very-low-density lipoprotein (VLDL), and triglycerides in umbilical cord blood to 1,369 children's teacher-rated psychosocial competence approximately 5 years later. Results of ordinal logistic regressions indicated that low levels of HDL, high levels of VLDL, and high levels of triglycerides predicted greater likelihood of being rated as less competent in domains of emotion regulation, self-awareness, and interpersonal functioning. Furthermore, these results generalized across ethnic background and children's sex and were not accounted for by variables reflecting mothers' psychological or physical health, children's physical health, or children's special education status. Together, these results identify fetal exposure to anomalous lipid levels as a possible contributor to subsequent psychological health and social functioning.

Project description:BackgroundConcerns have been raised that the COVID-19 pandemic could increase risk for adverse mental health outcomes, especially in young adults, a vulnerable age group. We investigated changes in depression and anxiety symptoms (overall and severe) from before to during the pandemic, as well as whether these changes are linked to COVID-19-related stressors and pre-existing vulnerabilities in young adults followed in the context of a population-based cohort.MethodParticipants (n = 1039) from the Quebec Longitudinal Study of Child Development reported on their depression (Centre for Epidemiological Studies Depression Scale, short form) and anxiety (General Anxiety Disorder-7 Scale) symptoms and completed a COVID-19 questionnaire during the first wave of the COVID-19 pandemic in the summer of 2020 (age 22 years). Assessments at age 20 (2018) were used to estimate pre-pandemic depression and anxiety symptom severity.ResultsWhile mean levels of depression and anxiety symptoms did not change from before to during the first wave of the COVID-19 pandemic (e.g., the mean of depressive symptoms was 9.30 in 2018 and 9.59 in 2020), we observed a slight increase in rates of severe depression (scores ≥ 21) from before (6.1%) to during (8.2%) the pandemic. Most COVID-19-related variables (e.g., loss of education/occupation, frequent news-seeking) - except living alone - and most pre-existing vulnerabilities (e.g., low SES, low social support) were not associated with changes in depression or anxiety symptoms. However, results varied as a function of pre-pandemic levels of depression and anxiety: depression and anxiety symptoms increased among adults with the lowest levels of symptoms before the pandemic, while they decreased among those with the highest levels of symptoms, possibly reflecting a regression to the mean.ConclusionsDepression and anxiety symptoms in young adults from Québec in Summer 2020 were mostly comparable to symptoms reported in 2018. Most COVID-19-related stressors and pre-existing vulnerabilities were not associated with changes in symptoms, except living alone and pre-existing symptoms of depression and anxiety. However, the increased rate of severe depression warrants further investigation.
