Eating behaviour patterns and BMI in Portuguese higher education students

Risk of Eating Disorders and Social Desirability among Higher Education Students: Comparison of Nutrition Students with Other Courses

The transition to college is a period of higher risk of the development of eating disorders, with nutrition/dietetics students representing a group of particular vulnerability. Hence, it is interesting to assess eating disorders, taking into consideration potential sources of bias, including social desirability. Our aims were to compare the risk of eating disorders between students of nutrition/dietetics and those attending other courses and to study potential social desirability biases. A total of 799 higher education students (81.7% females) aged 18 to 27 years old completed a questionnaire assessing the risk of eating disorders (EAT-26) and social desirability (composite version of the Marlowe-Crowne Social Desirability Scale). The proportion of students with a high risk of eating disorders was higher among females (14.5% vs. 8.2%, p = 0.044). Nutrition/dietetics students did not differ from those attending other courses regarding the risk of eating disorders. The social desirability bias when assessing the risk of eating disorders was overall low (EAT-26 total score: r = -0.080, p = 0.024). Social desirability correlated negatively with the Diet (r = -0.129, p < 0.001) and Bulimia and food preoccupation subscales (r = -0.180, p < 0.001) and positively with Oral self-control (r = 0.139, p < 0.001).

Eating Behaviours of Polish and Portuguese Adults-Cross-Sectional Surveys

Eating behaviours affect energy intake through the types and amounts of foods chosen and decisions about the beginning and ending of the eating process. This study aims to determine and compare the eating behaviours of Polish and Portuguese adults and, in addition, to establish the correlations between daily behaviours, food-approaches and food-avoidance behaviours, and BMI in both populations. The study was conducted between January 2023 and March 2023. Participants from Poland and Portugal responded to the AEBQ questionnaire and questions on eating habits and body-image self-perception. The research tool was a website-based survey questionnaire with single-choice questions. No significant differences related to BMI levels were found between the Polish and Portuguese adults in terms of their eating behaviours. Both groups were characterised by the increased intensity of their food-approach behaviours, which was directly correlated with increases in BMI. Greater snacking intensity and binge drinking were associated with higher BMI. The study revealed an increased prevalence of binge drinking in the Polish sample. The study also confirmed a higher frequency of food-approach behaviours in overweight and/or obese individuals and uncontrolled calorie intake in participants imposing dietary restrictions for weight loss. Nutrition education is needed to improve eating habits and food choices, as well as to prevent overweight and obesity in adults.

Eating Behaviors, Depressive Symptoms and Lifestyle in University Students in Poland

Young adulthood is the period from the late teens through the twenties and is associated with life transitions that could contribute to the development of obesity. Targeting this group will be critical to reversing the obesity epidemic. The aim of the study was to investigate the eating behaviors and lifestyle of healthcare students in Poland. We enrolled 227 students in the study. Convenience sampling was employed. Diet (Food Frequency Questionnaire), physical activity (International Physical Activity Questionnaire), depressive symptoms (Beck Depression Inventory), impulsivity (Barratt Impulsivity Scale), and eating behaviors (Three-Factor Eating Questionnaire) were assessed. One in three students exhibited depressive symptoms, one in four showed low levels of physical activity. More than 40% of the students did not consume vegetables at least once a day, and more than half did not consume fruit. Only approximately 50% of the students ate fish several times a month. There was an association between high scores of specific eating behaviors and body weight, adherence to the Mediterranean diet, and consumption of specific product groups (sweets, alcohol). The results of our study are expected to contribute to a better understanding of dietary habits and overweight/obesity in university students, and support the development of programs to promote healthy lifestyles in that population.

Association between impulsivity and orthorexia nervosa / healthy orthorexia: any mediating effect of depression, anxiety, and stress?

BACKGROUND

There is a lack of studies investigating the possible mediating role of psychological factors, such as depression, anxiety and stress on orthorexic eating behaviors. Given that personality attributes might affect the manifestation of psychological disorders, it was hypothesized that depression, anxiety and stress mediate the relationship between impulsivity-related traits and orthorexic eating, noting that previous research had evaluated the role of depression as a mediator between impulsivity and other pathological eating behaviors. The study objectives were to explore the mediating effect of depression, anxiety, and stress, on impulsivity and orthorexia nervosa, and healthy orthorexia.

METHODS

This cross-sectional study conducted between July and December 2019 recruited 519 Lebanese adults from seven community pharmacies randomly selected from a list provided by the Lebanese Order of Pharmacists.

RESULTS

Our results showed that depression and anxiety were positively correlated with ON. We also found a notable gender difference in findings: higher anxiety and female gender were significantly associated with higher TOS healthy orthorexia, while higher stress was associated with lower TOS healthy orthorexia. Finally, higher urgency was associated with lower TOS healthy orthorexia, while higher perseverance was significantly associated with higher TOS healthy orthorexia. Depression and anxiety partially mediated the association between perseverance and ON while anxiety and stress partially mediated the association between urgency and healthy orthorexia.

CONCLUSION

Our study suggests that depression, anxiety and stress play a mediating role between impulsivity and orthorexia nervosa/healthy orthorexia. Our findings provide a ground for future investigations of impulsive behaviors, psychopathology, and orthorexia in different populations.

Restrained Eating Is Associated with Lower Cortical Thickness in the Inferior Frontal Gyrus in Adolescents

Some eating patterns, such as restrained eating and uncontrolled eating, are risk factors for eating disorders. However, it is not yet clear whether they are associated with neurocognitive differences. In the current study, we analyzed whether eating patterns can be used to classify participants into meaningful clusters, and we examined whether there are neurocognitive differences between the clusters. Adolescents (n = 108; 12 to 17 years old) and adults (n = 175, 18 to 40 years old) completed the Three Factor Eating Questionnaire, which was used to classify participants according to their eating profile using k means clustering. Participants also completed personality questionnaires and a neuropsychological examination. A subsample of participants underwent a brain MRI acquisition. In both samples, we obtained a cluster characterized by high uncontrolled eating patterns, a cluster with high scores in restrictive eating, and a cluster with low scores in problematic eating behaviors. The clusters were equivalent with regards to personality and performance in executive functions. In adolescents, the cluster with high restrictive eating showed lower cortical thickness in the inferior frontal gyrus compared to the other two clusters. We hypothesize that this difference in cortical thickness represents an adaptive neural mechanism that facilitates inhibition processes.

Dysfunctional Patterns of Food Intake by Anxiety during Isolation by COVID-19 in Chile, Colombia and Mexico

The aim of this research was to compare food intake dysfunctional patterns score with the subjective perception of anxiety and sociodemographic characteristics of the participants in isolation by COVID-19 from Chile, Colombia, and Mexico. A cross-sectional research was carried out, with a virtual questionnaire of subjective perception of anxiety and the questionnaire of three 18-item feeding factors. 958 people of both sexes participated (F = 83%, M = 17%), mainly in the 18 to 35 age range. Dysfunctional eating patterns presented high scores in people who perceived anxiety, as well as in participants from Chile. Additionally, it was found that women present greater cognitive restriction and emotional intake, and college students showed greater disinhibition. In conclusion, the scores of the three dysfunctional eating patterns were higher in people with subjective perception of anxiety during social isolation due to COVID-19, and there were also differences according to country, sex, and educational level.

Percepción subjetiva de manejo emocional, ansiedad y patrones de ingesta relacionados con aislamiento por COVID-19

El periodo de aislamiento social se considera un detonante de ansiedad, y genera alteraciones en la forma de alimentarse. El objetivo de esta investigación fue determinar la relación entre la percepción subjetiva del manejo de las emociones y la ansiedad con los patrones disfuncionales de la ingesta en el periodo de aislamiento social por COVID-19, en participantes colombianos. La investigación es exploratoria de tipo transversal analítico. Un total de 450 colombianos mayores de 18 años (sexo: 82 % femenino y 18 % masculino) respondieron un cuestionario virtual sobre la percepción subjetiva del manejo de las emociones y la ansiedad; también, se aplicó el cuestionario de tres factores de alimentación para identificar patrones disfuncionales de la ingesta. Se reportó un riesgo 3 veces mayor de presentar ansiedad en las personas que manifestaron un manejo inadecuado de sus emociones. Asimismo, aquellos cuya percepción fue un inadecuado manejo de emociones y ansiedad presentaron mayor nivel de patrones disfuncionales de ingesta como la desinhibición (p < 0.0001) e ingesta emocional (p < 0.0001). Se concluyó que la percepción subjetiva del manejo inadecuado de las emociones y de ansiedad, incrementan la ingesta emocional y la desinhibición, en colombianos en aislamiento social.

Impact of inherent aspects of body image, eating behavior and perceived health competence on quality of life of university students

The aim of this study was to assess the impact of inherent aspects of body image, eating behavior and perceived health competence on quality of life of university students. Participants completed the instruments Body Shape Questionnaire (reduced version, BSQ-8B), Male Body Dissatisfaction Scale (reduced version, MBDS-R), Three-Factor Eating Questionnaire (reduced version, TFEQ-18), Perceived Health Competence Scale (bifactorial version, PHCS-B), World Health Organization Quality of Life Questionnaire-Short Form (WHOQoL-bref) and a questionnaire for characterization of sample. Psychometric properties of instruments were previously evaluated by confirmatory factor analysis. A hypothetical model for each sex was developed and tested. In both model surveys the aspects of the body image (BSQ-8B: body shape concern; MBDS-R: musculature and general body appearance), of eating behavior (TFEQ-18: cognitive restriction, emotional eating, and uncontrolled eating) and of the perceived health competence (PHCS-B: expectations of achieving the desired health results and competence in health behaviors) were used as direct predictors on quality of life (WHOQoL-bref). The variables age, medication use for body change, food supplement use for body change, and body mass index (BMI) were inserted in the aspects of the body image. The variables course shift, initial expectation regarding the course, self-reported performance in the course, concomitant work activities to studies, and economic class were inserted into the quality of life. The model surveys were evaluated using structural equation modeling. A level of significance of 5% was used. A total of 2,198 university students (female = 63.5%), including 1,151 Brazilians and 1,047 Portuguese, participated of study (locally representative samples). The average age of women was 20.8 ± 2.4 years and of men was 21.3 ± 3.3 years. The psychometric properties of the instruments were adequate, except for the PHCS, which was adjusted for each sex. The models presented variance explained of 54% and 49% for women and men, respectively. In both sexes, the students' perceived health competence and academic variables contributed significantly to their quality of life, and age, BMI, and medication and supplement use were significant factors relating to how a student views his or her body image. Women's quality of life was associated with body shape concern and emotional eating aspects. Men's quality of life was associated with general body appearance and cognitive restriction aspects. These results can be used to create and implement educational programs to improve quality of life of university students.

Psychopathological correlates of eating behavior among Portuguese undergraduate students

OBJECTIVES

The aim of this study was to explore the relationships between eating behavior dimensions and psychopathological symptoms among Portuguese undergraduate students.

METHODS

We studied 258 participants (62.4% women) regarding eating behavior dimensions (emotional, external and binge eating, flexible and rigid control of eating behavior, and eating self-efficacy), psychopathological distress (as assessed by the Brief Symptom Inventory), and body mass index. In addition to studying bivariate associations between eating behavior dimensions and psychopathological subscales and indexes, what we believe to be a novel analytical approach, considering simultaneously the effects of the overall level of psychopathological distress and the relevance of specific symptoms on the eating behavior dimensions.

RESULTS

Emotional, external, and binge eating had positive correlations with psychopathological symptomatology, whereas eating self-efficacy was negatively associated.

CONCLUSIONS

Multivariate analysis showed that the overall level of psychopathological distress (combined with body mass index, among women) had a larger effect on eating behavior than the relevance of specific symptoms.

The Brazilian version of the three-factor eating questionnaire-R21: psychometric evaluation and scoring pattern

PURPOSE

This study aimed to evaluate the psychometric properties and scoring pattern of the Brazilian version of the three-factor eating questionnaire-r21 (TFEQ-R21).

METHODS

Data were collected from 410 undergraduate students. Confirmatory factor analysis was conducted to examine the factor structure of the TFEQ-R21. Convergent and discriminant validity also was assessed. Cluster analysis was performed to investigate scoring patterns.

RESULTS

In assessing the quality setting, the model was considered satisfactory (χ ²/gl = 2.24, CFI = 0.97, TLI = 0.96, RMSEA = 0.05). The instrument was also considered appropriate in relation to the discriminant and convergent validity. There was a positive correlation between body mass index and the dimensions of cognitive restraint (r _s  = 0.449, p < 0.001) and emotional eating (r _s  = 0.112, p = 0.023). Using cluster analysis three respondent profiles were identified. The profile "A" was associated with appropriate weight, the "B" was characterized by high scores in cognitive restraint dimension, and the cluster "C" focused individuals who had higher scores on the uncontrolled eating and emotional eating dimensions.

CONCLUSIONS

The Brazilian version of TFEQ-R21 has adequate psychometric properties, and the identified response profiles offer a promising prospect for its use in clinical practice, in weight loss interventions.

Development of relative body mass (BMI) of students from Łódź, depending on the selected environmental, psychological and sociological factors

The human height-to-weight ratio is an important parameter of the body homeostasis. Currently, the most popular measurement determining the relationship between body mass and height is the Quetelet II indicator, called Body Mass Index (BMI). The aim of this study is an evaluation of the differences in the height-to-weight ratios, depending on selected environmental, psychological and sociological factors in people studying at higher education institutions in Łódź. The research was conducted among students of higher education institutions in Łódź, by electronic means or with the use of an anonymous survey. It consisted of 28 closed single or multiple choice questions. Statistical analysis was made of complete results of the research involving 135 people, both males and females, aged between 19-26. It was revealed that the factors related to higher BMI values in students are the following: the presence of a tendency in the students to gain weight themselves, and a tendency to gain weight present in their mothers, an evaluation of their own body mass as excessive, regularly smoking cigarettes and rarely undergoing medical check-ups. Among the factors connected with lower BMI values are: regular coffee consumption, perception of their own body mass as being too low, and also obtaining systolic pressure values below 110 mm Hg. Additionally, a positive correlation between taking up physical activity and higher values of systolic blood pressure (p<0.05) was shown. Among the subjects, it was found that 92% of the underweight women declared that their body mass and figure were normal. In the case of women with optimal BMI values, 40% stated that their body mass was excessive. In the case of men the problem was reverse: 50% of the subjects who were either overweight or obese claimed that their body mass was within the norm. The factors that significantly influence body proportion differences among students include the subject’s and the subject’s mother’s tendency to put on weight, self-evaluation of their own body mass, the values of systolic blood pressure, coffee consumption and cigarette smoking, as well as the frequency of medical check-ups.

Eating behaviour among undergraduate students. Comparing nutrition students with other courses

Our main aim was to compare eating behaviour between Portuguese undergraduate nutrition students and students attending other courses. Several eating behaviour dimensions were compared between 154 nutrition students and 263 students from other areas. Emotional and external eating were assessed by the Dutch Eating Behavior Questionnaire, dietary restraint was measured using the flexible and rigid control of eating behaviour subscales, binge eating was measured using the Binge Eating Scale, and eating self-efficacy using the General Eating Self-Efficacy Scale. Higher levels of flexible and rigid control were found in nutrition students from both sexes when compared to students from other courses. Female nutrition students also presented higher binge eating levels than their colleagues from other courses. To our knowledge no other work has previously assessed all eating behaviour dimensions considered in the current study among nutrition students. Besides the results by themselves, the data obtained from this study provide several clues to further studies to be developed regarding the still rarely approached issue of eating behaviour among nutrition students.
