Personal History:

I was born and raised in Baltimore. After graduating from Loyola College in MD with a B.S. in biology and working for several years in a breast cancer laboratory, I enrolled in the doctoral program in Human Nutrition at the Johns Hopkins Bloomberg School of Public Health. In my graduate studies, I examined familial factors influencing obesity and physical activity among adolescents in Baltimore City.

I received my first faculty appointment (Assistant Professor, Department of Pediatrics) in 2009 followed by a secondary appointment in the Department of Epidemiology and Public Health in 2011. Since becoming an Assistant Professor, I have been competitively selected to attend two national leadership trainings: the Dannon Nutrition Leadership Institute (2009) and Association of American Medical Colleges Early Women in Medicine and Science Leadership Training (2011); and have been selected to attend New Connections Symposia/ Research & Coaching Clinics (sponsored by the Robert Wood Johnson Foundation for junior faculty from disadvantaged backgrounds, 2009-2011). These opportunities provided mentorship from nationally recognized scholars, connected me to a powerful group of peer leaders, and helped build leadership skills that I have implemented in my current role.

I am currently building three areas of research expertise:

  1. Measures Development. Much of my research has focused on developing and validating measures of obesity-related constructs. For example, we developed and validated a Toddler Silhouette Scale (Hager et al, Obesity, 2010) to determine maternal accuracy and satisfaction with the body size of her toddler. We applied this scale to low-income mothers, finding that mothers of overweight toddlers were inaccurate yet satisfied with their toddler’s body size, with opposite findings for mothers of underweight toddlers (accurate and dissatisfied; Hager et al, Arch Ped Adol Med, 2012). We also validated a 2-item Food Insecurity Screen (Hager et al, Pediatrics, 2010) that is being used in multiple national studies. I received funding from the Robert Wood Johnson Foundation through an Active Living Research/New Connections grant to develop and validate an instrument to measure the perceptions of the physical activity environment within schools (2009-2011) that we are currently using in a school-based study.

  2. Assessment of Physical Activity As a graduate student, I received training in physical activity assessment from my mentor, Margarita Treuth, PhD, an exercise physiologist. Because of this skill, I have been invited to serve as co-investigator on 2 obesity prevention randomized trials. I have also received two grants to validate ankle accelerometry, one with adolescent girls (NORC P&F, 2009-2010) and one with toddlers (NORC P&F, 2010-2011).

  3. Pediatric Obesity Prevention My research perspective in this area has evolved due to my experience working with Active Living Research and to an overall shift in the field. I have outlined below my pediatric obesity prevention work and the evolution of my focus moving from micro-level influences (individual/family) to macro-level influences (policy):

    1. Individual/ Family. As a graduate student, I worked with Challenge!, an obesity prevention trial based in Social Cognitive Theory targeting low-income urban African American adolescents (Black, Hager et al, Pediatrics, 2010). My dissertation was titled “Familial Determinants of Overweight and Physical Activity Behavior Change Among Urban African American Adolescents”. I also served as co-investigator for the family-based Toddler Overweight Prevention Study (USDA/NICHD, 2005-2011).
    2. Schools. I then extended my research focus to schools and the school environment to expand the reach of interventions. I became a co-investigator for Challenge! in Schools (NICHD, 2008-2013) and was the principal investigator on a small grant that sought to develop a program to promote a healthy school environment (Wilson Foundation, 2009-2010).
    3. Built Environment. I am currently shifting my focus beyond the school and into the neighborhood, by seeking out opportunities to gain skills evaluating the built environment. I was competitively selected to attend the week-long Built Environment Assessment Training Institute (2012) that provided a detailed introduction to methods for assessing the built environment. I recently received a career development award from the University of Maryland BIRCWH K12 Scholar Program which provides funding and protected time to gain skills in GIS mapping and multi-level modeling. I recently had a manuscript published that examines the characteristics of the neighborhood surrounding schools that are associated with physical activity among adolescent girls (Hager et al, Ann Beh Med, 2013). I will also begin work on an R03 grant (NICHD) to examine environmental influences on toddler diet and physical activity.
    4. Policy. Over the past year, I have built a collaborative partnership with local and state policy makers, including the Maryland Department of Health and Mental Hygiene (DHMH), the Maryland State Department of Education (MSDE) and the Institute for a Healthiest Maryland (a collaboration between the University of Maryland, Baltimore and DHMH to bring together academic institutions with local public health departments and community leaders to provide evidence-based resources that promote health and reduce disparities). I am a co-investigator on a CDC community transformation grant subcontract from DHMH to promote healthy eating and active living in schools throughout the state of Maryland through wellness policy implementation, partnering with the MSDE (2011-2014). This partnership has been expanded through a CDC Special Interest Program grant to evaluate barriers/enablers to wellness policy implementation in low-income, urban schools in Maryland (2012-2014).

My ultimate goal is to reduce obesity-related health disparities among low-income, African American girls and women through programs, policies, and environmental change. Although my career has begun to take on a policy/built environment focus, I believe that the most effective way to change behavior is through a multi-level approach (i.e.: environment/policy change + individual behavior change).
