Purpose

Secretive eating, characterized by eating privately to conceal being seen, may reflect eating- and/or body-related shame, be associated with depression, and correlate with binge eating, which predicts weight gain and eating disorder onset. Increasing understanding of secretive eating in youth may improve weight status and reduce eating disorder risk. This study evaluated the prevalence and correlates of secretive eating in youth with overweight or obesity.

Methods

Youth (N = 577) presented to five research/clinical institutions. Using a cross-sectional design, secretive eating was evaluated in relation to eating-related and general psychopathology via linear and logistic regression analyses.

Results

Secretive eating was endorsed by 111 youth, who were, on average, older than youth who denied secretive eating (mean age = 12.07 ± 2.83 versus 10.97 ± 2.31). Controlling for study site and age, youth who endorsed secretive eating had higher eating-related psychopathology and were more likely to endorse loss of control eating and purging than their counterparts who did not endorse secretive eating. Groups did not differ in excessive exercise or behavioral problems. Dietary restraint and purging were elevated among adolescents (≥13y) but not children (<13y) who endorsed secretive eating; depression was elevated among children, but not adolescents, who endorsed secretive eating.

Conclusions

Secretive eating may portend heightened risk for eating disorders, and correlates of secretive eating may differ across pediatric development. Screening for secretive eating may inform identification of problematic eating behaviors, and understanding factors motivating secretive eating may improve intervention tailoring.

Objective

This pilot study aimed to refine and test an adaption of family-based treatment (FBT) for eating disorders that addressed the distinct clinical needs of adolescents with overweight or obesity in the absence of eating disorder pathology. Our hypothesis was that FBT for paediatric obesity (FBT-PO) would be feasible to implement and superior to a nutrition education counselling (NEC) condition delivered to both parents and patients, thereby controlling for key information dissemination across groups while manipulating active therapeutic content and strategy.

Method

Seventy-seven adolescents were randomized to FBT-PO or NEC across two sites.

Results

Results supported our core prediction, in that weight status among adolescent study participants receiving FBT-PO remained stable while increasing among participants randomized to NEC. Attrition was high in both conditions.

Conclusions

FBT-PO, while not seeming to yield a marked decrease in body mass index z-score, may arrest an otherwise-occurring weight-gain trajectory for these adolescents. This efficacy finding is consistent with the overall PO literature supporting parental involvement in the treatment of PO. Future research efforts should address retention in FBT-PO.
