Measuring the Weight Status, Primary Care Usage and Dietary Intake in the Pediatric Emergency Department
Measuring the Weight Status, Primary Care Usage and Dietary Intake in the Pediatric Emergency Department
Childhood obesity is a major area of concern for health care and public health. Overweight
 children are more likely overweight and obese adults. Chronic health problems associated with
 adult obesity are now occurring more frequently in children. Because of the associated health
 problems and potential for long term struggles with obesity, intervention early in life is
 essential for addressing the obesity epidemic. Some intervention work in this area has
 focused on the pediatric primary care setting in order to utilize the influence and
 credibility of medical providers. Unfortunately, primary care visits are often too short to
 spend a significant amount of time on issues of diet, weight and nutrition.

 There has been very little work exploring the potential of alternative care settings, such as
 the pediatric Emergency Department (ED) in addressing childhood obesity. While provider time
 is also limited in the ED, there is often a considerable amount of downtime during emergency
 department visits that could be valuable time for patient and parent education. There may
 also be an opportunity to reach parents and children in the ED who do not regularly utilize
 primary care. In order to explore the possibility of pediatric obesity interventions in
 Children's Pediatric Emergency Department, we will need to measure the prevalence of obesity
 in the population that utilizes the Children's ED. The height of patients seen in the ED is
 not routinely measured, which makes calculating BMI to determine obesity impossible. This
 study, establishing the prevalence of obesity in Children's Emergency Department will lay the
 groundwork for future work addressing obesity in the ED.
Background/Significance Childhood obesity is a well-documented public health crisis. Data
 from the most recent National Health and Nutrition Examination survey (NHANES) indicate that
 the prevalence of obesity is 8.4% in 2 to 5-year-olds, 17.7% in 6 to 11-year-olds, and 20.5%
 in 12 to 19-year-olds (1). Large racial/ethnic disparities in risk for obesity are already
 present by the preschool years (2). In 2 to 5-year-olds, 3.5% of non-Hispanic white children
 are obese, compared to 11.3% of non-Hispanic black and 16.7% of Hispanic children (1). Many
 health problems that were previously associated only with adult obesity are now being seen in
 youth, including the metabolic syndrome, type 2 diabetes, and cardiovascular abnormalities
 (3). Obesity tracks into adulthood, highlighting the need for early intervention (4).
 Overweight children have more chronic conditions, a greater risk of emergency department
 visits, and significantly higher costs for common pediatric hospitalizations (5-7).
 Successfully addressing the childhood obesity epidemic will require coordinated and
 collective efforts across many settings including multiple healthcare settings (8). Obesity
 interventions are increasingly being developed that utilize the influential role and
 credibility of pediatric primary care providers by integrating interventions into healthcare
 settings (9). Unfortunately, primary care visits are often short (average primary visit is
 16.4 minutes) and leave little time for addressing obesity in detail, highlighting the need
 to also incorporate assessment and treatment in alternative care settings (i.e., emergency
 care) (10, 11).

 There is little research on what role alternative healthcare setting could play in addressing
 childhood obesity. The pediatric ED is currently untapped as a setting for obesity screening,
 treatment and prevention (12). Yet, childhood obesity has important implications for
 emergency medicine and trauma care, and the pediatric ED may be shouldering a
 disproportionate burden of this disease compared to other healthcare settings (13, 14). Not
 addressing a patient's obesity in the ED setting is a missed opportunity, especially when
 many visits are obesity- related (e.g., asthma, type 2 diabetes, fractures), and weight
 reduction in specific subgroups could lead to a decrease in future ED utilization. The
 pediatric ED may not seem like an ideal location for addressing childhood obesity but many
 visits are for non-emergent/urgent conditions and these types of visits provide a window for
 screening and intervention (12,15). Families spend a substantial amount of time in the ED
 waiting for laboratory/radiology results and disposition. In 2013, the average length of stay
 in the Children's EDs was 155 minutes in Minneapolis and 143 minutes in St. Paul, valuable
 time that could be used for obesity screening, education, and connection to external
 resources. The pediatric ED has the potential to be an important additional healthcare
 setting for obesity screening, education, and linkage to external resources, but much more
 research is needed (12,13,16).

 Three previous studies have examined obesity rates in the pediatric ED, each finding a higher
 prevalence of obesity compared to the general population (12,13,16). Prendergast et al.
 conducted a retrospective chart review and found a prevalence of obesity of 29% in a Chicago
 pediatric ED, nearly double the national average of 17% (12). The other two studies collected
 cross-sectional data from small samples in urban pediatric EDs and found a prevalence of
 obesity of 24% (13) and 21.6% (16). Only one study has tested obesity screening in the
 pediatric ED (16). Vaughn et al. found that all parents were receptive to obesity screening
 and prevention in the ED, regardless of race (16). They also found that only 7.6% of parents
 reported that their child's regular physician had counseled them regarding their child's
 weight, highlighting the need for obesity screening in additional healthcare settings (16).
 These studies indicate that pediatric EDs are seeing a population of patients at high risk
 for obesity, many of whom may not be receiving screening or counseling from their regular
 physician. Other topics in emergency medicine have received far greater coverage in the
 literature, including smoking cessation, injury prevention and substance abuse (13). With the
 dramatic increase in pediatric obesity, research on obesity in the pediatric ED is especially
 warranted as innovative strategies and collaboration across healthcare settings will be
 needed to successfully address this epidemic.

 Currently, the prevalence of obesity in patients who utilize the pediatric ED at Children's
 Hospitals and Clinics of Minnesota is unknown. Because of time constraints, the height of
 patients seen in the pediatric ED are not routinely measured or recorded in the Electronic
 Medical Record (EMR). Establishing prevalence of obesity in this population is not possible
 without measuring the height of PED patients to determine BMI. Establishing the prevalence in
 the population of patients who utilize the pediatric ED will lay the groundwork for future
 grant proposals and research in this area.

 Research Questions:

 1. What is the prevalence of obesity in the Children's ED patient population?

 2. What is the association between weight status and ED utilization for injury, asthma and
 mental health?

 Study Design We will conduct a cross-sectional cohort study of patients aged 2-10 in
 Children's ED.

 Methods ED research assistants will screen the ED log for patients in the 2-10 age range
 triaged level 3-5. Research assistants will randomly determine 1 out of 5 patients to
 approach for study enrollment. After the consent process is completed, the research assistant
 will measure and record the child's height, and ask the parent to complete a short
 questionnaire.
Inclusion Criteria:

 1. Emergency Severity Index (ESI) Triage levels 3-5

 2. Patient between 2 and 10 years of age (inclusive)

 3. Parent able to consent

 Exclusion Criteria:

 1. Transferred patients
