Relation of self-weighing to future weight gain and onset of disordered eating symptoms.

ABSTRACT: OBJECTIVE:Frequent self-weighing is recommended in weight loss interventions and may prevent weight gain. However, concerns regarding the associations between self-weighing and eating disorders have been expressed and the relations between self-weighing and weight gain/eating pathology have not been examined prospectively. We tested whether (a) frequency of baseline self-weighing in college students with weight concerns predicted weight change over 2-year follow-up, (b) this relation was moderated by eating disorder symptoms, and (c) self-weighing predicted future eating disorder symptoms. METHOD:Data were merged from two trials evaluating obesity/eating disorder prevention programs in 762 students (Mage = 18.7; 86% women). Participants reported how often they weighed themselves at baseline; body mass index (BMI) and eating disorder symptoms were assessed over 2-year follow-up. RESULTS:Baseline self-weighing predicted weight gain, with more frequent weighers experiencing greater gains (i.e., +0.8 of BMI) over follow-up. This relation was moderated by the frequency of binge eating but not weight/shape concerns or compensatory behaviors; the combination of more frequent self-weighing and binge eating was associated with greatest weight gain (+1.6 of BMI). More frequent weighers also reported higher onset of compensatory behaviors, relative to non-self-weighers (odds ratio = 3.90, 95% confidence interval [1.76, 8.75]). CONCLUSIONS:Young adults who weighed themselves more frequently had greater weight gain than those who self-weighed less frequently, especially those who engaged in binge eating, and were at risk for future unhealthy compensatory behaviors. Findings suggest that frequent self-weighing may have negative effects for some young adults, and that relations between self-weighing and weight control outcomes require further investigation.

Project description:ObjectivePreadolescent loss-of-control-eating (LOC-eating) is a risk factor for excess weight gain and binge-eating-disorder. We evaluated feasibility and acceptability of a preventive family-based interpersonal psychotherapy (FB-IPT) program. FB-IPT was compared to family-based health education (FB-HE) to evaluate changes in children's psychosocial functioning, LOC-eating, and body mass.MethodA randomized, controlled pilot trial was conducted with 29 children, 8 to 13 years who had overweight/obesity and LOC-eating. Youth-parent dyads were randomized to 12-week FB-IPT (n = 15) or FB-HE (n = 14) and evaluated at post-treatment, six-months, and one-year. Changes in child psychosocial functioning, LOC-eating, BMI, and adiposity by dual-energy-X-ray-absorptiometry were assessed. Missing follow-up data were multiply imputed.ResultsFB-IPT feasibility and acceptability were indicated by good attendance (83%) and perceived benefits to social interactions and eating. Follow-up assessments were completed by 73% FB-IPT and 86% FB-HE at post-treatment, 60% and 64% at six-months, and 47% and 57% at one-year. At post-treatment, children in FB-IPT reported greater decreases in depression (95% CI -7.23, -2.01, Cohen's d = 1.23) and anxiety (95% CI -6.08, -0.70, Cohen's d = .79) and less odds of LOC-eating (95% CI -3.93, -0.03, Cohen's d = .38) than FB-HE. At six-months, children in FB-IPT had greater reductions in disordered-eating attitudes (95% CI -0.72, -0.05, Cohen's d = .66) and at one-year, tended to have greater decreases in depressive symptoms (95% CI -8.82, 0.44, Cohen's d = .69) than FB-HE. There was no difference in BMI gain between the groups.DiscussionFamily-based approaches that address interpersonal and emotional underpinnings of LOC-eating in preadolescents with overweight/obesity show preliminary promise, particularly for reducing internalizing symptoms. Whether observed psychological benefits translate into sustained prevention of disordered-eating or excess weight gain requires further study.
