Insights

This study tests an enhanced motivational interviewing (MI) intervention delivered by paediatricians/nurse practitioners (Ped/NPs) and registered dietitians (RDs) to reduce child body mass index (BMI). The enhanced primary care approach aims to improve prevention and management of paediatric overweight and obesity.

Area of Science:

  • Pediatric Health
  • Public Health Interventions
  • Behavioral Science

Background:

  • Primary care settings are underutilized for pediatric overweight and obesity prevention and management.
  • Previous trials showed motivational interviewing (MI) delivered by paediatrician/nurse practitioners (Ped/NPs) and registered dietitians (RDs) significantly impacts child body mass index (BMI).

Purpose of the Study:

  • To test the effectiveness of an enhanced primary care-based MI counseling intervention on child BMI.
  • To evaluate an intervention involving Ped/NPs and RDs using MI for pediatric weight management.

Main Methods:

  • A cluster randomized effectiveness trial involving 24 Ped/NPs across 18 primary care practices.
  • Children aged 3-11 years with BMI at or above the 85th percentile identified via electronic health records (EHRs).
  • Intervention group parents receive approximately 10 MI counseling sessions over 2 years (in-person with Ped/NP and telephonic with RD); usual care group receives standard care.

Main Results:

  • The primary outcome is the change in child BMI percentile over the study period.
  • Data will be collected from EHRs, billing records, surveys, and counseling call notes.
  • The trial is registered under NCT03177148 and is currently in the pre-results phase.

Conclusions:

  • This enhanced MI intervention has the potential to improve pediatric weight management outcomes in primary care.
  • Findings will be disseminated through publications, conferences, and AAP channels.

Obesity

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Drug Dosing: Obese Patients

In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...

Models of Health Promotion and Illness Prevention II

The person's health status fluctuates continually, varying from being in good health to becoming ill and returning to being healthy. To understand the concept of illness prevention, there are two models. First, the health-illness continuum model is a graphic representation of an individual's wellness. It states that a person is considered healthy in the absence of physical disease and the presence of good emotional health.
The agent-host-environment model states that disease results...

Models of Health Promotion and Illness Prevention I

A model is a theoretical way to understand a concept or an idea. Models can overcome barriers to health regardless of diverse economic and cultural backgrounds. In addition, models make the task easier by providing different ways to approach complex issues. There are two major health promotion models: the health belief model and the health promotion model.
The health belief model (HBM) attempts to predict health-related behavior in specific belief patterns. According to the HBM, a person's...
