Current research

Examining psychological (e.g., anxiety, depression, ADHD, etc.) and physical health co-morbidities associated with pediatric obesity

Pediatric overweight and obesity is associated with significant negative medical and mental health outcomes. Better understanding how psychological and physical health conditions impact children and families, and their potential response to weight management interventions, can help clinicians and researchers provide prevention and treatment strategies that are the most effective.

Development and evaluation of pediatric obesity family-based and technology-based behavioral weight management interventions

Pediatric obesity is a significant public health issue due to its high prevalence and negative impacts on physical and psychological health. My lab has developed group-based clinic interventions for youth and families, as well as technology-based interventions using remote patient monitoring to provide treatment specific to pediatric obesity.

Exploring issues related to diversity, culture, and family factors that intersect with engagement in health behaviors and health disparities

Various cultural factors play health-promoting roles in adults with chronic medical conditions but there has been little focus on cultural factors in pediatric populations. Understanding cultural and parenting factors and associated psychosocial functioning in pediatric medical conditions is important in order to address health disparities and to develop culturally appropriate and sensitive prevention and treatment strategies.

Program evaluation for a multidisciplinary pediatric obesity clinic

It is important for current and future pediatric obesity specialty clinics to implement evidence based practices to improve patient physical health and mental health outcomes. We have examined various sociodemographic factors related to clinic attendance and related outcomes to inform clinical practices and improvements in multidisciplinary services provided.
