Dr. Buchholz is a clinical psychologist and lead in outcomes management and research at the Centre for Healthy Active Living (CHAL); she is a clinical investigator with the Ready, Set, GO research team at the Children’s Hospital of Eastern Ontario Research Institute, and an adjunct research professor in the Department of Psychology at Carleton University.
Dr. Buchholz is a co-investigator on the REAL study, ‘Research on Eating and Adolescent Lifestyles’, an Ottawa-based longitudinal study examining shared risk factors between eating disorders and obesity. Dr. Buchholz is involved as a co-investigator in several national multisite studies related to pediatric obesity, including the CANadian Pediatric Weight management Registry (CANPWR). She advocates and is involved in research related to social determinants of health, weight bias and discrimination, Health At Every Size (HAES), mental health, body image, and psychosocial clinical outcomes.

Measuring severe obesity in pediatrics using body mass index‑derived metrics from the Centers for Disease Control and Prevention and World Health Organization: a secondary analysis of CANadian Pediatric Weight management Registry (CANPWR) data.
18/09/2023
To examine the (i) relationships between various body mass index (BMI)-derived metrics for measuring severe obesity (SO) over time based the Centers for Disease Control and Prevention (CDC) and World Health Organization (WHO) references and (ii) ability of these metrics to discriminate children and adolescents based on the presence of cardiometabolic risk factors. In this cohort study completed from 2013 to 2021, we examined data from 3- to 18-year-olds enrolled in the CANadian Pediatric Weight management Registry.

Appearance satisfaction mediates the relationship between recreational screen time and depressive symptoms in adolescents
18/07/2022
Recreational screen time, including activities that involve using a screen for leisure (i.e., computer, videogames, television; U.S. National Library of Medicine, 2018) is a popular and predominantly sedentary pastime. Epidemiological data show that many adolescents exceed the <2-hr daily screen time recommendation based on the Canadian 24-hr Movement Guidelines for Children and Youth (Tremblay et al., 2016) by more than 6 hr each day (Leatherdale & Harvey, 2015). As screen time activities exert increased influence on adolescents' lives, it has spurred researchers to examine the implications of their use. High levels of recreational screen time activities have been associated with a host of physical health issues, such as sleep problems (Cabre-Riera et al., 2019), health risk behaviors, (i.e., illicit drug use; Rücker, Akre, Berchtold,& Suris, 2015) and risk of overweight status and obesity (Fang, Mu, Liu, & He, 2019). Alarmingly, one additional hour of daily screen time has been linked to 172 additional servings of beverages high in sugar and 368 additional servings of ‘unhealthy’ snack foods each year among adolescents (Hicks, Jillcot Pitts, Lazorick, Fang, & Rafferty, 2019).

Examining the Bidirectional Association Between Body Esteem and Body Mass Index During Adolescence

The decreasing trajectory of body esteem over time suggests the need for prevention efforts to improve body esteem throughout adolescence.

Coping in adolescents: A mediator between stress and disordered eating
16/06/2021
Overall, the findings from this study are among the first to demonstrate significant mediation relationships between stress (both negative life events and perceived stress) and ED symptomatology for emotion-oriented coping in both male and female adolescents. These findings suggest that using emotion-oriented coping in response to real or perceived stress increases the risk for ED symptomatology across all adolescents. These findings suggest that intervention or prevention efforts aimed at teaching adolescents how to tackle or cope with a problem by aiming to address the stressor itself (i.e. task-oriented coping) versus trying to escape the emotion that accompanies it may have a protective effect against emerging ED symptomatology, and likely full-blown eating disorders in the face of stress during a vulnerable developmental period.
