Stress and psychological constructs related to eating behavior are associated with anthropometry and body composition in young adults.

ABSTRACT: BACKGROUND:The transition to college is associated with weight gain, but the relation between eating behavior indicators and anthropometric outcomes during this period remains unclear. OBJECTIVE:We aimed to evaluate sex differences in stress, emotional eating, tendency to overeat, and restrained eating behavior, and determine whether the psycho-behavioral constructs assessed immediately prior to starting college are associated with anthropometry and adiposity at the start of college, and with first-semester weight gain. METHODS:A prospective study administered the Three Factor Eating Questionnaire (TFEQ), Satter Eating Competence Inventory, and Perceived Stress Scale (PSS) to 264 participants one month before college. Body composition was assessed via dual energy X-ray absorptiometry (DXA) at the start of college, and anthropometry (weight, height, waist circumference [WC]) was collected at the beginning and end of the first semester. Ordinary least squares regression tested the cross-sectional association of baseline psychological and behavioral scales with baseline DXA and anthropometry, and the longitudinal association with change in anthropometry. RESULTS:Among 264 participants, 91% (241) had baseline data, and 66% (173) completed follow-up. In sex-adjusted linear regression models, baseline TFEQ disinhibited and emotional (DE; EE) eating sub-scales were positively associated with baseline weight (P?=?0.003; DE, P?= 0.014; EE), body mass index (BMI, P?=?0.002; DE, P?=?0.001; EE), WC (P?= 0.004; DE, P?=?0.006; EE) and DXA fat mass index (P?=?0.023; DE, P?=?0.014; EE). Baseline PSS was positively associated with subsequent changes in weight and WC among males only (Pinteraction?=?0.0268 and 0.0017 for weight and WC, respectively). CONCLUSION:College freshmen with questionnaire scores indicating a greater tendency to overeat in response to external cues and emotions tended to have greater weight, BMI, and WC at the start of college. Males with higher perceived stress at college entrance subsequently gained significantly more weight in the first semester, but no such relation was evident in females.

Project description:BackgroundMany people aim to eat healthily. Yet, affluent food environments encourage consumption of energy dense and nutrient-poor foods, making it difficult to accomplish individual goals such as maintaining a healthy diet and weight. Moreover, goal-congruent eating might be influenced by affects, stress and intense food cravings and might also impinge on these in turn. Directionality and interrelations of these variables are currently unclear, which impedes targeted intervention. Psychological network models offer an exploratory approach that might be helpful to identify unique associations between numerous variables as well as their directionality when based on longitudinal time-series data.MethodsAcross 14 days, 84 diet-interested participants (age range: 18-38 years, 85.7% female, mostly recruited via universities) reported their momentary states as well as retrospective eating episodes four times a day. We used multilevel vector autoregressive network models based on ecological momentary assessment data of momentary affects, perceived stress and stress coping, hunger, food craving as well as goal-congruent eating behaviour.ResultsNeither of the momentary measures of stress (experience of stress or stress coping), momentary affects or craving uniquely predicted goal-congruent eating. Yet, temporal effects indicated that higher anticipated stress coping predicted subsequent goal-congruent eating. Thus, the more confident participants were in their coping with upcoming challenges, the more they ate in line with their goals.ConclusionMost eating behaviour interventions focus on hunger and craving alongside negative and positive affect, thereby overlooking additional important variables like stress coping. Furthermore, self-regulation of eating behaviours seems to be represented by how much someone perceives a particular eating episode as matching their individual eating goal. To conclude, stress coping might be a potential novel intervention target for eating related Just-In-Time Adaptive Interventions in the context of intensive longitudinal assessment.

Project description:Abstract Objectives To examine the association between meal habits (i.e., eating breakfast every day, usually ≥80% fullness at breakfast, and not eating snacks at night), body composition and the subsequent changes in mood status in young adults. Methods This is a longitudinal follow-up study based on a randomized trial (ClinicalTrials.gov Identifier: NCT03828812). Young adults were recruited based in a university campus in Taipei City, Taiwan. In total, 125 participants were recruited and 103 completed the follow-ups. Measured body composition (TANITA BC-418) and moods (Depression Anxiety Stress Scale, DASS) were assessed at baseline, the third month and 15th month from baseline. Baseline meal habits were based on the participants’ recall of their diets in the month before interview. We used mixed-effect model to test the association of baseline total body fat percentage and trunk body fat percentage and moods during follow-ups, adjusting for age, sex, baseline body mass index (BMI), food security status. Results After controlling for sex, age, BMI, and food security status at baseline, having breakfast every day at baseline was associated with 2.04 (se = 0.78, P = 0.0098) lower anxiety score and with 2.58 (se = 1.26, P = 0.0409) lower stress score at baseline. Meal habits were not associated with the subsequent changes in mood status. As for body composition, one % of trunk body fat replacing one % of non-trunk body fat at baseline was associated with 1.19 (se = 0.57, P = 0.0381) higher depression score, 1.02 (se = 0.47, P = 0.0327) higher anxiety score, 2.06 (se = 0.76, P = 0.0075) higher anxiety score at baseline. One % of non-trunk body fat percentage was associated with 2.60 (se = 1.02, P = 0.0116) lower anxiety score, as trunk body fat % is controlled. Baseline body fat composition parameters were not associated with the temporal changes in mood scores. The significance patterns were similar after adjusting for baseline physical activity level, assessed by International Physical Activity Questionnaire. Conclusions Breakfast habits and body composition, especially trunk body fat, was associated with university-based young adults’ emotional health status.

Project description:Regular physical activity (PA) is an important part of the treatment of several medical conditions, including overweight and obesity, in which there may be a weakened appetite control. Eating behaviour traits influence weight control and may be different in active and sedentary subjects. This paper reports the relationships between the time spent in sedentary behaviour and physical activity (PA) of different intensity, and eating behaviour traits in young, healthy adults. Additionally, it reports the results of a six-month-long, randomized, controlled trial to examine the effect of an exercise intervention on eating behaviour traits. A total of 139 young (22.06 ± 2.26 years) healthy adults (68.35% women) with a Body Mass Index (BMI) of 24.95 ± 4.57 kg/m2 were enrolled. Baseline assessments of habitual PA were made using wrist-worn triaxial accelerometers; eating behaviour traits were examined via the self-reported questionnaires: Binge Eating, Three-Factor Eating Questionnaire-R18 and Control of Eating Questionnaire. The subjects were then randomly assigned to one of three groups: control (usual lifestyle), moderate-intensity exercise (aerobic and resistance training 3¨C4 days/week at a heart rate equivalent to 60% of the heart rate reserve (HRres) for the aerobic component, and at 50% of the 1 repetition maximum (RM) for the resistance component), or vigorous-intensity exercise (the same training but at 80% HRres for half of the aerobic training, and 70% RM for the resistance training). At baseline, sedentary behaviour was inversely associated with binge eating (r = -0.181, p < 0.05) and with uncontrolled eating (r = -0.286, p = 0.001). Moderate PA (MPA) was inversely associated with craving control (r = -0.188, p < 0.05). Moderate-to-vigorous PA (MVPA) was directly associated with binge eating (r = 0.302, p < 0.001) and uncontrolled eating (r = 0.346, p < 0.001), and inversely associated with craving control (r = -0.170, p < 0.015). Overall, PA was directly associated with binge eating (r = 0.275, p = 0.001), uncontrolled eating (r = 0.321, p < 0.001) and emotional eating (r = 0.204, p < 0.05). Additionally, only emotional eating was modified by the intervention, increasing in the vigorous-intensity exercise group (p < 0.05). In summary, we observed that time spent in sedentary behaviour/PA of different intensity is associated with eating behaviour traits, especially binge eating in young adults. In contrast, the six-month exercise intervention did not lead to appreciable changes in eating behaviour traits.
