Family Functioning and Childhood Obesity Treatment: A Family Systems Theory-Informed Approach

Abstract

Childhood obesity recommendations advise providers to use family-based care for the treatment of youth and adolescent obesity. Family-based care, defined as the inclusion of a caregiver and a youth, is commonly conducted through behavioral interventions that target the dietary and physical activity behaviors of the attending parent-youth dyads. However, focusing on behaviors isolated to the parent and youth neglects the rest of the family members, and the larger rules, routines, communication, and dynamics in the family. Family-based interventions grounded in family systems theory (FST) target family dynamics to influence weight-related behaviors through higher-level changes in the family. The utility of using FST in childhood obesity treatment has not been extensively conceptualized or applied. Few outcome studies have reported on variables representative of FST, and even fewer FST interventions have been conducted. Because of the lack of detail on the application of FST to childhood obesity treatment, providers are left with little clarity on how to use FST in clinical encounters. We provide the background and evidence for use of FST, detail how families organize around weight-related behaviors that contribute to obesity, and on the basis of their organization, what type of treatment might be beneficial, FST-informed or family-based behavioral interventions. Finally, a suggested family-based clinical algorithm is provided detailing the use of FST through assessment, intervention, and follow-up that can be refined over time by providers and researchers committed to viewing obesity in the context of the family and family dynamics.
