This study aimed to investigate the role of the psychological impact of environments rich in palatable foods on three aspects of eating behavior: cognitive restraint (CR), uncontrolled eating (UE), and emotional eating (EE). The hypotheses were as follows: (a) The psychological impact (i.e., motivation to eat) of an environment rich in palatable fo...
Obesity is associated with inflammation and an increased risk of cardiovascular disease and premature mortality, as well as a range of other conditions. Obesity is a growing global problem, not only in adults, but also in children and adolescents. Therefore, the present study aimed to assess the effects of a one-year interdisciplinary intervention...
Purpose: This study investigated the acute effect of anodal transcranial direct current stimulation (a-tDCS) over the left dorsolateral prefrontal cortex (DLPFC) on appetite, energy intake, food preferences, and mood states in the luteal and follicular phases of the menstrual cycle in women presenting premenstrual syndrome. Methods: Sixteen women (...
This work aims to provide a comprehensive overview of the use of front‐of‐package nutritional labeling (FOPL), identify and characterize the major existing FOPL systems, examine the impact of FOPL systems on consumer behavior, and discuss future perspectives. The searched databases were PubMed, Scopus, and Web of Science, and papers in English, Por...
The present study has three main objectives: a) to analyse, for the first time, the factor structure of the Control of Eating Questionnaire (CoEQ) in a Brazilian sample; b) to explore, through in-depth interviews, motivators and consequences of food cravings among participants with high scores on the CoEQ; and c) to analyse whether and how the powe...
The Power of Food Scale (PFS) is a questionnaire for self-assessing the motivation to consume palatable foods, especially in environments where food is abundant and constantly available. This study aimed to a) assess the factorial structure of the PFS in a Brazilian sample and b) examine the relationship between the power of food and body image dis...
The aim of this study was to understand how dietitians' body size influences perceived competence and warmth, based on the Stereotype Content Model (SCM). Online data were collected from 1,039 Brazilians, who were either laypeople, registered dietitians, or nutrition students. Participants rated the competence and warmth dimensions of three dietiti...
The Food Choice Questionnaire (FCQ) was applied to assess the motivations for daily food choices and associated factors in a Brazilian sample. Data were collected from January to July 2019 from 525 individuals over 18 years old recruited face-to-face in different places (e.g., university, public squares, health posts), using a convenient, intention...
(1) Background: Obesity is associated with significant social consequences, and individuals with obesity are regularly affected by weight-related stigmatization experiences. This study compares antifat attitudes among registered dietitians (RD), nutrition students, and laypeople and assesses which factors related to the perceived causes of obesity...
This study aimed to assess consumers’ perceptions about the impact of consumption of different foods on health and body weight, as well as to identify risk perceptions about food-related chronic diseases. Face-to-face questionnaires were conducted with 525 Brazilians. Individuals were asked about their perception of risks associated with the consum...
This study aimed to evaluate the food choice motives in a sample in Brazil and to identify how socioeconomic characteristics and risk perceptions about chronic diseases and weight gain affect these motives. The Food Choice Questionnaire (FCQ) is an instrument to analyze the motivations for food choice. The FCQ was completed by 525 adult individuals...
Background
The perception that a food is ‘healthy’ or ‘low fat’ has been proposed as an important issue influencing eating behaviour. This study had two aims: a) to test the perceived health value of two popular foods in Brazil and, b) to investigate the impact of consuming these foods on subsequent food reward. Individual differences in adiposity...
O objetivo do estudo foi avaliar a confiança e o calor de modelos de nutricionistas de diferentes características e relacionar essa avaliação com a percepção da autoimagem e satisfação corporal. Os 152 participantes avaliaram seis modelos de nutricionistas (variando em gênero, idade e perfil corporal), na perspectiva da teoria Social Content Stereo...
The Leeds Food Preference Questionnaire (LFPQ) measures separable psychological components of food reward (Liking and Wanting). In this study a cultural adaptation of the LFPQ for a Brazilian population (LFPQ-BR) was examined by comparing liking and wanting scores in fasted and fed states and their association with adiposity and disturbed eating. A...
Objectives:
Obesity is a multifactorial disease characterized by the presence of the pro-inflammatory state associated with the development of many comorbidities, including bone turnover marker alterations. This study aimed to investigate the role of the inflammatory state on bone turnover markers in obese adolescents undergoing interdisciplinary...
Objective:
Leptin is an adipokine released mainly by adipose tissue, with many functions including regulation of energy balance. However, little is known about the effect of LEPR polymorphism on orexigenic and anorexigenic neuropeptides. Thus, the aim of the present study is to verify the influence of LEPR polymorphism (rs2767485) on serum orexige...
Avaliar a associação entre o grau de circunferência da cintura (CC) e doença hepática gordurosa não alcoólica (DHGNA) em adolescentes obesos de ambos os sexos, avaliados de acordo com quartis de CC.
Objective:
To assess the relationship between the degree of waist circumference (WC) and nonalcoholic fatty liver disease (NAFLD) in obese adolescents of both genders, analyzed according to quartiles of WC.
Methods:
Cross-sectional study that involved 247 obese adolescents aged 12-19 years. Mean values of the nutritional parameters and serum ana...
Obesity is characterised by low-grade inflammation, which increases the metabolic syndrome (MetS) and cardiovascular risks. The aim of the present study was to verify the role of multicomponent therapy in controlling the MetS, inflammation and carotid intima-media thickness (cIMT) in obese adolescents. The second aim was to investigate the relation...
Objectives. This study aimed to investigate the effect of vitamin D on cardiovascular risk in obese adolescents.Methods. Thirty (16 females/14 males) post-puberty obese adolescents (15-19 years) were involved and measurements of inflammatory biomarkers, body composition, visceral fat, and vitamin D (serum and intake) were performed. The adolescents...
Several studies have sought to clarify the association between adolescent obesity and psychological distress. Recently a biological link between leptin resistance and depression has been proposed. The aim of the present study was to examine changes in leptin concentrations as a potential predictor of reduced depression symptoms in obese adolescents...
Background:
The low-grade inflammatory state in obesity leads to insulin resistance and endothelial dysfunction, which promote cardiovascular diseases in individuals with obesity. The purpose of this study was to evaluate the early effects of weight loss achieved through bariatric surgery on the inflammatory and prothrombotic states. This study al...
Background/Objectives
Obesity is related to inflammation and cardiovascular disease. The increase in saturated fatty acid intake (SFA) can potentiate cardiovascular risks. The aim of this study was to assess the influence of change in SFA on carotid intima-media thickness (cIMT), metabolic profile and anti/pro-inflammatory adipokines in obese adole...
