The Female Athlete Body project study: 18-month outcomes in eating disorder symptoms and risk factors.

ABSTRACT: OBJECTIVE:To evaluate the efficacy of the Female Athlete Body project (FAB) in reducing eating disorder (ED) symptoms and risk factors. METHOD:This study was a community participatory three-site, two-arm, cluster randomized controlled trial (RCT). Female collegiate athletes (N = 481) were randomly assigned by team to the FAB intervention, a behavioral ED risk factor reduction program, or a waitlist control condition. Primary analyses examined 18-month effects for ED pathology. Secondary analyses examined risk factors and correlates (e.g., thin-ideal internalization, negative mood, Female Athlete Triad knowledge, and body mass index [BMI]). RESULTS:Linear mixed effects models with team as a cluster level variable and study condition as a between-subjects variable revealed significantly reduced dietary restraint in FAB teams relative to control teams. FAB teams also reported significantly fewer objective and subjective binge episodes than control teams. Finally, FAB teams showed significantly lower thin-ideal internalization and increased BMI at 18-months. No other significant differences were found. DISCUSSION:This RCT examined the effects of a short intervention on ED pathology and risk factors in female collegiate athletes through 18-month follow-up. This trial is one of only three trials with female athletes that have shown long-term reductions in any ED symptoms or produced positive effects on ED risk factors. The present study is the first to find such effects with athletes using a brief (i.e., 4?hr) intervention at 18-month follow-up. Although small effects were found, the current trial provides valuable lessons about future design and implementation of similar trials with athletes. TRIAL REGISTRATION:Clinical trials NCT01735994.

Project description:ObjectiveNeurotensin and xenin are two closely related anorexigenic neuropeptides synthesized in the small intestine that exert diverse peripheral and central functions. Both act via the neurotensin-1-receptor. In animal models of obesity reduced central concentrations of these peptides have been found. Dysregulations of the acute and chronic stress response are associated with development and maintenance of obesity. Until now, associations of both peptides with stress, anxiety, depressiveness, and eating disorder symptoms have not been investigated. The aim of the present study was to examine associations of neurotensin and xenin with these psychological characteristics under conditions of obesity.Materials and methodsFrom 2010 to 2016 we consecutively enrolled 160 inpatients (63 men and 97 women), admitted due to obesity and its mental and somatic comorbidities. Blood withdrawal und psychometric tests (PSQ-20, GAD-7, PHQ-9, and EDI-2) occurred within one week after admission. We measured levels of neurotensin and xenin in plasma by ELISA.ResultsMean body mass index was 47.2 ± 9.5 kg/m2. Concentrations of neurotensin and xenin positively correlated with each other (women: r = 0.788, p < 0.001; men: r = 0.731, p < 0.001) and did not significantly differ between sexes (p > 0.05). Women generally displayed higher psychometric values than men (PSQ-20: 58.2 ± 21.7 vs. 47.0 ± 20.8, p = 0.002; GAD-7: 9.7 ± 5.8 vs. 7.1 ± 5.3, p = 0.004; PHQ-9: 11.6 ± 6.6 vs. 8.8 ± 5.9, p = 0.008; EDI-2: 50.5 ± 12.8 vs. 39.7 ± 11.9, p < 0.001). Only women showed positive correlations of both neuropeptides with stress (neurotensin: r = 0.231, p = 0.023; xenin: r = 0.254, p = 0.013), anxiety (neurotensin: r = 0.265, p = 0.009; xenin: r = 0.257, p = 0.012), depressiveness (neurotensin: r = 0.281, p = 0.006; xenin: r = 0.241, p = 0.019) and eating disorder symptoms (neurotensin: r = 0.276, p = 0.007; xenin: r = 0.26, p = 0.011), whereas, men did not (p > 0.05).ConclusionNeurotensin and xenin plasma levels of female obese patients are positively correlated with perceived stress, anxiety, depressiveness, and eating disorder symptoms. These associations could be influenced by higher prevalence of mental disorders in women and by sex hormones. In men, no correlations were observed, which points toward a sex-dependent regulation.
