Background: Access to traditional mental health services in Canada remains limited, prompting exploration into digital alternatives. The Government of Ontario initiated access to two internet-based cognitive behavioral therapy (iCBT) programs, LifeWorks AbilitiCBT and MindBeacon TAiCBT, for adults with mental health issues.

Methods: An uncontrolled observational study utilizing secondary retrospective program data was conducted to evaluate the reach, uptake, and psychological symptom changes among participants engaging with either iCBT program.

Background: Federated digital identifiers (FDIs) have been cited to improve the interoperability of data and information management while enhancing the privacy of individuals verifying their identity on the web. Many countries around the world have implemented FDIs in various sectors, such as banking and government. Similarly, FDIs could improve the experience for those wanting to access their health care information; however, they have only been introduced in a few jurisdictions around the world, and their impact remains unclear.

Background: Digital health interventions (DHIs) are a central focus of health care transformation efforts, yet their uptake in practice continues to fall short of their potential. In order to achieve their desired outcomes and impact, DHIs need to reach their target population and need to be used. Many factors can rapidly intersect between this dynamic of users and interventions.

Background: Recent research has shown that pregnant individuals experience weight stigma throughout gestation, including negative comments and judgement associated with gestational weight gain (GWG). Weight bias internalization (WBI) is often a result of exposure to weight stigma and is detrimental to biopsychological health outcomes. The purpose of this study was to explore WBI in pregnancy and compare scores based on maternal weight-related factors including pre-pregnancy body mass index (BMI), obesity diagnosis and excessive GWG.

The purpose of this scoping review was to map the challenges, strategies, and lessons learned from high-income countries that can be mobilized to inform decision-makers on how to best implement virtual primary care services during and after the COVID-19 pandemic. Findings of our scoping review identified the barriers and strategies within the Quadruple Aim components, which may prove to be an effective implementation strategy for virtual care adoption in primary care settings. virtual care COVID-19 were searched in MEDLINE, EMBASE, and CINAHL on August 10, 2020, and Scopus was searched on August 15, 2020.

International guidelines recommend women with an overweight or obese body mass index (BMI) aim to reduce their body weight prior to conception to minimize the risk of adverse perinatal outcomes. Recent systematic reviews have demonstrated that interpregnancy weight gain increases women's risk of developing adverse pregnancy outcomes in their subsequent pregnancy. Interpregnancy weight change studies exclude nulliparous women.

Purpose: Limited research has measured the effect of physical activity (PA) interventions on health-related quality of life (HRQoL) among pre-school-aged children. This study evaluates the effect of the Activity Begins in Childhood (ABC) cluster-randomized controlled trial designed to increase PA in the ages 3-5 years on HRQoL.

Methods: This was a cluster-randomized controlled trial where the intervention group included PA education delivered to daycare providers only, or daycare providers and parents.

Considering the coronavirus disease 2019 (COVID-19) pandemic, scholars were encouraged to cease collocated meetings. Many researchers have turned to remote collaboration to continue group-based projects. This paper focuses on the structure, processes, and outcomes that a group of physically distanced, embedded researchers used to collaborate across Canada to produce research outputs prior to the pandemic.

Objective: As the prevalence of obesity increases, more women are at risk of potentially experiencing weight stigma in prenatal health care settings. The objective of this scoping review was to summarize the primary literature assessing potential causes of weight stigma in prenatal health care settings and synthesize recommendations for health care providers to improve clinical practice.

Methods: A search strategy was developed combining the terms pregnancy, weight stigma, obesity, and prenatal care.

Objective: Fetal exposure to an intrauterine environment affected by maternal obesity and excessive gestational weight gain increases the likelihood of infants born large for gestational age and childhood obesity. This study examined behavioural factors and lifestyle practices associated with women's perceived attainability of meeting the 2009 Institute of Medicine (IOM) weight gain guidelines.

Methods: Cross-sectional data were collected from pregnant (n = 320) and postpartum (n = 1179) women who responded to the validated Canadian Electronic Maternal (EMat) health survey.

Context: The Health System Impact (HSI) Fellowship, an innovative training program developed by the Canadian Institutes of Health Research's Institute of Health Services and Policy Research, provides PhD-trained health researchers with an embedded, experiential learning opportunity within a health system organization.

Methods/design: An electronic Delphi (eDelphi) study was conducted to: (1) identify the criteria used to define success in the program and (2) elucidate the main contributions fellows made to their organizations. Through an iterative, two-round eDelphi process, perspectives were elicited from three stakeholder groups in the inaugural cohort of the HSI Fellowship: HSI fellows, host supervisors and academic supervisors.

Background: Self-diagnosis is the process of diagnosing or identifying a medical condition in oneself. Artificially intelligent digital platforms for self-diagnosis are becoming widely available and are used by the general public; however, little is known about the body of knowledge surrounding this technology.

Objective: The objectives of this scoping review were to (1) systematically map the extent and nature of the literature and topic areas pertaining to digital platforms that use computerized algorithms to provide users with a list of potential diagnoses and (2) identify key knowledge gaps.

Problem: Too much or too little gestational weight gain (GWG) can negatively impact maternal and fetal health, according to Institute of Medicine Guidelines.

Background: Health care providers are key players in providing reliable evidence-informed prenatal advice related to appropriate GWG. However, there appears to be inconsistent GWG communication among healthcare providers during prenatal care.

Importance: Gestational weight gain (GWG) is an independent and modifiable factor for a healthy pregnancy. Gestational weight gain above or below the Institute of Medicine Guidelines has been shown to impact both maternal and fetal health (eg, gestational diabetes, hypertension, downstream obesity). Healthcare providers (HCPs) have the potential to be reliable sources of evidence-based weight information and advice during pregnancy.

Background: In Canada, one year after bariatric surgery follow-up appointments become less frequent and surgical recipients must cope with weight management more independently. Up to 50% of patients experience weight regain by two years post-surgery. Understanding the lived experiences of those who have gone through the bariatric process may shed light on what is needed to support others moving forward.
