Background: Obesity is associated with serious medical conditions including diabetes, hypertension, and heart disease. It also contributes to decreased productivity at work and school, financial strain, and reduced quality of life.

Purpose of Project: To address this problem, a nurse practitioner-led screening and intervention program was piloted at a primary care clinic in southern San Diego. The tool provides a standardized method for screening individuals and their families for nutrition and physical activity deficits associated with obesity, as well as appropriate and effective interventions to prevent and manage obesity.

Methods: The Family Nutrition and Physical Activity (FNPA) screening tool is a behaviorally based assessment which evaluates multiple constructs of health. It has demonstrated consistent utility for predicting children’s risk of becoming overweight or developing obesity. Both the screening evaluation and interventions can be applied to the entire family.

Results: Across the participants, preintervention data revealed an average BMI of 34.3, and initial FNPA scores averaged 57 out of 80 possible points. After the prescription of interventions, average BMI dropped to 32.5 and average FNPA scores increased to 61 points. All participants reported comfortability discussing the results of the survey and agreed that the interventions were realistic for them.

Evaluation: The FNPA is a standardized screening tool which identifies obesogenic behaviors and assists providers as they identify interventions designed to optimize nutrition, exercise, and lifestyle habits. These interventions may help prevent and reduce obesity prevalence rates among primary care patients. Additional research is needed to further explore the use of the FNPA tool in the primary care setting.
