Do Psychological and Behavioural Factors Change Over Pregnancy?

Objectives: To investigate how psychological and behavioural factors change from the first to the last half of pregnancy.

Methods: In this prospective cohort study, we assessed the changes in psychological and behavioural factors across 10 domains among 445 women (mean age = 30.9 years) in Ontario, Canada.

The mental health experience of treatment-seeking military members and public safety personnel: a qualitative investigation of trauma and non-trauma-related concerns.

Introduction: Paramedics, firefighters, police officers and other public safety personnel (PSP) as well as Canadian Armed Forces (CAF) members are frequently exposed to stressors and demanding work environments. Although their specific work-related tasks may vary, a commonality between these occupations is the significant likelihood of repeated exposure to potentially psychologically traumatic events (PPTE) over the course of their careers. Due in part to these repeated exposures, CAF members and PSP are at an elevated risk of mental health concerns including posttraumatic stress disorder.

A goal set too high: factors associated with planning excess gestational weight gain in a prospective cohort study.

Objective: This study aimed to understand physical, knowledge, psychological, and lifestyle factors associated with planned excess gestational weight gain (GWG), a strong and potentially modifiable predictor of actual excess GWG, which contributes to maternal and child obesity along with other adverse maternal and fetal outcomes.

Methods: This is a secondary analysis of data from a prospective cohort study where women completed a questionnaire in early pregnancy. Women were asked to report their planned GWG, which was then categorized as above, within, or below the Institute of Medicine (IOM) guidelines.

Gestational weight gain outside the 2009 Institute of Medicine recommendations: novel psychological and behavioural factors associated with inadequate or excess weight gain in a prospective cohort study.

Background: Previous studies have noted traditional physical, demographic, and obstetrical predictors of inadequate or excess gestational weight gain, but the roles of psychological and behavioral factors are not well established. Few interventions targeting traditional factors of gestational weight gain have been successful, necessitating exploration of new domains. The objective of this study was to identify novel psychological and behavioral factors, along with physical, demographic, and obstetrical factors, associated with gestational weight gain that is discordant with the 2009 Institute of Medicine guidelines (inadequate or excess gain).

Predictors of Gestational Weight Gain Examined As a Continuous Outcome: A Prospective Analysis.

Excess gestational weight gain (GWG) is common and adversely affects both mothers and offspring, including increasing the risk of maternal and childhood obesity. GWG is typically examined categorically, with women grouped into categories of those who gain above, within, and below guideline recommendations. Examining GWG as a continuous variable, rather than categorically, allows for a consideration of GWG at a finer level of detail, increasing precision.

Does Excess First- or Second-Trimester Weight Gain Predict Excess Total Gestational Weight Gain? A Multicentre Prospective Cohort Study.

Objectives: Early excess gestational weight gain (GWG) has been examined as a predictor of total excess GWG in a few international studies; however, Canadian data are lacking. We sought to determine whether early (first- and second-trimester) excess GWG predicted total excess GWG.

Methods: We conducted an a priori planned secondary analysis of a multicentre prospective study of English-speaking Ontario women with a singleton pregnancy between 8 and 20 weeks gestation.

Competing priorities: a qualitative study of how women make and enact decisions about weight gain in pregnancy.

Background: Despite ample clinical evidence that gaining excess weight in pregnancy results in negative health outcomes for women and infants, more than half of women in Western industrialized nations gain in excess of national guidelines. The influence of socio-demographic factors and weight gain is well-established but not causal; the influence of psychological factors may explain some of this variation.

Methods: This is the qualitative portion of an explanatory sequential mixed-methods study designed to identify predictive psychological factors of excess gestational weight gain (QUAN) and then explain the relevance of those factors (qual).

Prediction of excess pregnancy weight gain using psychological, physical, and social predictors: A validated model in a prospective cohort study.

Objective: To develop and validate a prediction model for excess pregnancy weight gain using early pregnancy factors.

Design: Prospective cohort study.

Setting: We recruited from 12 obstetrical, family medicine, and midwifery centers in Ontario, Canada.

Personality differences in the susceptibility to stress-eating: The influence of emotional control and impulsivity.

Purpose: Stress has been associated with deviations from typical eating patterns, with respect to both food choice and overall caloric intake. Both increases and decreases in dietary intake have been previously noted in response to stress. The purpose of the present study was to determine whether the affect regulation strategies of emotional control and impulsivity predict susceptibility to eating in response to stress.

The effect of academic stress and attachment stress on stress-eaters and stress-undereaters.

It is well established that stress is related to changes in eating patterns. Some individuals are more likely to increase their overall food intake under conditions of stress, whereas others are more likely to consume less food when stressed. Attachment style has been linked to disordered eating and eating disorders; however, comparisons of eating behaviors under attachment versus other types of stress have yet to be explored.

Binge Eating Predicts Excess Gestational Weight Gain: A Pilot Prospective Cohort Study.

Objective: One half of women's gestational weight gain (GWG) exceeds the recommended amount. In attempting to prevent this, randomized trials targeting diet and/or exercise have been generally unsuccessful. In response, study of psychological factors has been called for.

Psychological antecedents of excess gestational weight gain: a systematic review.

Background: Excess gestational weight gain (GWG), which has reached epidemic proportions, is associated with adverse outcomes during pregnancy and postpartum obesity in women and children. Psychological variables represent potentially modifiable factors. Moreover, previous systematic reviews on GWG interventions have called for the need for a clearer understanding of psychological factors affecting GWG.

Psychological factors and trimester-specific gestational weight gain: a systematic review.

Excess gestational weight gain (GWG), which has reached epidemic proportions, is associated with numerous adverse pregnancy outcomes. Early pregnancy provides a unique opportunity for counseling pregnant women since many women are motivated to engage in healthy behaviors. A systematic review was conducted to summarize the relation between psychological factors and trimester-specific GWG, i.

Using a knowledge transfer framework to identify factors facilitating implementation of family-based treatment.

Objective: To conduct a qualitative study to identify factors that would facilitate the transfer of the research evidence on Family-Based Treatment (FBT) into clinical practice.

Method: Fundamental qualitative description guided sampling, data collection, and analytic decisions for this study. Forty therapists who treat children and adolescents under the age of 18 with Anorexia Nervosa (AN) and belong to Ontario's provincial network of specialized eating disorder services completed an in-depth interview focusing on elements proposed by the Lavis knowledge transfer framework.

Decision-making processes for the uptake and implementation of family-based therapy by eating disorder treatment teams: a qualitative study.

Objective: To explore the decision-making processes involved in the uptake and implementation of evidence-based treatments (EBTs), namely, family-based treatment (FBT), among therapists and their administrators within publically funded eating disorder treatment programs in Ontario, Canada.

Method: Fundamental qualitative description guided sampling, data collection, and analytic decisions. Forty therapists and 11 administrators belonging to a network of clinicians treating eating disorders completed an in-depth interview regarding the decision-making processes involved in EBT uptake and implementation within their organizations.

The integration of a specialized eating disorders nurse on a general inpatient pediatric unit.

Eating disorders (EDs) affect approximately 5% of Canadian adolescents. Patients experiencing acute medical complications of their illness are often treated on a general pediatric ward with mixed populations. Twenty-one health care providers shared their experiences caring for youth with EDs and provided feedback regarding the integration of a specialized ED nurse (ED-RN).

Understanding the uptake of family-based treatment for adolescents with anorexia nervosa: therapist perspectives.

Objective: To explore and describe therapists' perceptions of the factors affecting their uptake of family-based treatment (FBT) for adolescents with anorexia nervosa (AN).

Method: Fundamental qualitative description guided the sampling and data collection in this study. A purposeful sample of 40 therapists providing treatment to youth with AN, completed an in-depth interview.
