Introduction: Lifestyle and gaming habits may influence chess players' adhesion to healthy dietary patterns. This study aims to characterize Portuguese chess players sociodemographics, playing traits, adherence to the Mediterranean diet (MD), dietary supplement (DS) consumption, physical activity level, degree of internet gaming disorder (IGD) and to study predictors of adherence to the MD. Methods: Data was gathered using an online survey disseminated through social networks, which included questions regarding sociodemographics, chess playing habits, the PREDIMED questionnaire, DS consumption, the International Physical Activity Questionnaire, and the Internet Gaming Disorder Scale. Results: The 192 respondents (93.8 % males) had a mean of 41 years (SD = 14), high education (mean = 15.1 y, SD = 1.7), and played chess for 6.3 hours (SD = 9.7) a week. Most (58.9 %, n = 113) reported moderate adherence to the MD, 30.2 % (n = 58) ingested DS, 64.1 % (n = 123) adhered to the WHO Physical Activity Recommendations, and no subject was classified with IGD. Higher Elo scores correlated with higher red/processed meat consumption (OR = 4.935, p = 0.005). A greater volume of chess play related to higher consumption of pastries and sweets (OR = 3.127, p = 0.007). Higher IGD scores were associated with lower adhesion to the MD (OR = 1.067, p = 0.019). Conclusions: The most dedicated chess players may be less concerned with maintaining a balanced diet and may require supervision from health professionals. Funding: None to disclose.

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).

Background: The role of mindful eating (ME) and intuitive eating (IE) in improving eating behavior, diet quality, and health is an area of increasing interest. Objective: The objective of this review was to identify the instruments used to assess ME and IE among higher education students and outcomes related to these dimensions. Methods: This review was carried out according to the PRISMA statement, through systematic searches in PubMed, Web of Science, PsycInfo, and Scopus. The inclusion criteria selected for higher education students, levels of ME and/or IE reported, and observational and clinical studies. The exclusion criteria selected against reviews, qualitative studies, and case studies. Quality was assessed using the Academy of Nutrition and Dietetics Quality Criteria Checklist. Results: A total of 516 initial records were identified, from which 75 were included. Cross-sectional studies were the most common research design (86.7%). Most studies were conducted with samples that were predominantly female (90.7%), White (76.0%), aged 18 to 22 years (88.4%), with BMI < 25 kg/m2 (83.0%), and in the United States (61.3%). The Intuitive Eating Scale (IES), the Mindful Eating Questionnaire (MEQ), and their different versions were the most used instruments. The outcomes most studies included were eating behavior and disorders (77.3%), anthropometric assessments (47.8%), mental health (42.0%), and body image (40.6%). Regarding the quality of studies, 34.7% of studies were assigned a positive, 1.3% a negative, and 64.0% a neutral rate. Conclusions: IES and MEQ were the most used instruments. RCT and cohort studies are scarce, and future research with a higher level of quality is needed, especially on the topics of food consumption, diet quality, and biochemical markers.

As the esports industry grows, marketing campaigns for fast food, soft drinks, alcoholic and energy drinks, and dietary supplements at related events intensify. Portuguese and Brazilian esports players’ dietary patterns remain unexplored. This study aimed to characterize the dietary and gaming habits of esports players. We applied an anonymous, open online survey to a convenience sample of esports players that included the PREDIMED and the Internet Gaming Disorder Scale. The survey was shared through email and social media platforms, including Facebook, Twitter, Instagram, Discord, WhatsApp, and Twitch. The sample (n = 579) was predominantly male (91.4%), averaged 26.1 (SD = 7.0) years, and 25.9 (SD = 5.5) kg/m2. Most reported a weak (53.7%) adherence to the Mediterranean diet. Almost a third (32.3%) consumed dietary supplements. Our sample presented a low adhesion to the Mediterranean dietary pattern, low consumption of fruit and vegetables, and high consumption of fast food, red and processed meat, soft drinks, and dietary supplements, including caffeine-based supplements. Dietary supplement consumption was related to a higher adhesion to the Mediterranean diet, and a higher level of professionalization and internet gaming disorder correlated with a lower adhesion. In conclusion, we infer that Portuguese and Brazilian esports players follow an unbalanced diet.

Background: It is well established that older adults are at risk for malnutrition due to several social and non-social determinants, namely physiological, psychosocial, dietary and environmental determinants. The progression to malnutrition is often insidious and undetected. Thus, nutritional assessment should consider a complex web of factors that can impact nutritional status (NS). The primary objective of this study was to assess the NS of older adults attending senior centres (SCs) and to identify its predictors. Methods: This cross-sectional study enrolled a sample of community-dwelling older adults in Lisbon. NS was assessed using Mini Nutritional Assessment (MNA®). Malnutrition or malnutrition risk (recategorised into a single group) was predicted using binary logistic regression models, considering those participants classified as having a normal NS as the reference group. Data were collected through face-to-face interviews and anthropometric indices were measured according to Isak procedures. Results: A sample of 337 older adults, with an average age of 78.4 years old (range 66–99), mostly women (n = 210; 62.3%), were enrolled. Older adults at risk of malnutrition accounted for 40.7% of the sample. Being older (OR = 1.045, CI 95% [1.003–1.089], p = 0.037), having a worse perception of health status (OR = 3.395, CI 95% [1.182–9.746], p = 0.023), having or having had depression (OR = 5.138, CI 95% [2.869–9.201], p < 0.001), and not having or having had respiratory tract problems (OR = 0.477, CI 95% [0.246–0.925], p = 0.028) were independent predictors of malnutrition or malnutrition risk. An intermediate time of SC attendance was associated with a lower probability of malnutrition or risk (OR = 0.367, CI 95% [0.191–0.705], p = 0.003). Conclusions: NS among older adults has a multifactorial aetiology, with a strongly social component and is related to health circumstances. Further research is needed to timely identify and understand nutritional risk among this population.

Eating behavior adopted during adolescence may persist into adulthood. The aims of this study were to identify eating behavior patterns among Portuguese adolescents and to explore whether groups differ in terms of early life and family characteristics, severity of depressive symptoms, and body mass index (BMI) z-score. Participants were 3601 13-year-olds enrolled in the birth cohort Generation XXI. Eating behavior was assessed using the self-reported Adult Eating Behavior Questionnaire (AEBQ), validated in this sample. The severity of depressive symptoms was measured through the Beck Depression Inventory (BDI-II), and data on sociodemographic and anthropometrics were collected at birth and 13-years-old. Latent class analysis was conducted, and associations were estimated using multinomial logistic regression models. Five patterns of individuals were identified: “Picky eating”, “Disinterest towards food”, “Food neophilia”, “Emotional eating”, and “Food attractiveness”. The adolescents’ sex, maternal education, BMI z-score, and severity of depressive symptoms were significantly associated with the identified patterns. In particular, adolescents with a higher BMI z-score were more likely in “Food neophilia” while individuals with more severe depressive symptoms were in the “Picky eating”, “Emotional eating”, and “Food attractiveness” patterns. These findings suggest a starting point for the development and planning of targeted public health interventions.

Malnutrition is widespread among older adults, and its determinants may differ between countries. We compared Portuguese and Turkish non-institutionalized older adults regarding nutritional status, sociodemographic, health and anthropometric characteristics and studied the relationships between nutritional status and those characteristics. This cross-sectional study analyzed data from 430 Portuguese and 162 Turkish non-institutionalized older adults regarding sociodemographics, health conditions, the Mini-Nutritional Assessment (MNA-FF) and anthropometry. Turkish older adults were more likely to be malnourished or at risk of malnutrition and had lower average BMI but a higher calf circumference. A higher proportion of the Portuguese sample had tooth loss, diabetes, hypertension, oncologic diseases, kidney diseases, osteoarticular problems or eye problems, while less had anemia. A better nutritional status (higher MNA-FF score) was found among the Portuguese, males, people using dentures, those without tooth loss, hypertension, cardiovascular diseases, anemia or oncological diseases and was related to younger age, higher BMI and a higher calf circumference. Malnutrition and its risk were higher among older adults from Turkey, despite Portuguese older adults presenting a higher prevalence of chronic diseases. Being female, older age, tooth loss, hypertension, anemia, CVD or oncological disorders and having a lower BMI or CC were associated with higher rates of malnutrition among older adults from Portugal and Turkey.

Introduction: Functional foods are those that promote health and well-being and/or decrease the risk of certain chronic diseases. It is known that young people’ knowledge about functional foods is low. The aim of this study is to assess the psychometric proprieties of the “Attitudes towards Functional Foods Scale” in a sample of adolescents and, based on that analysis, adapting the scale for its use among this population group. Material and Methods: After a pre-test, the scale was applied to 340 students attending the 3rd cycle of basic education in Terceira island (Azores, Portugal), whose ages ranged between 11 and 19 years (mean = 14.0, standard deviation = 1.2). We analyzed the scale’s internal consistency and construct validity. Results: The study of the psychometric proprieties led to the exclusion of one item. Cronbach’s alpha (α = 0.876) showed a good internal consistency of the scale, and factor analysis revealed that, as the original (adults) version, it presents an unifactorial structure. Discussion: The scale showed to be an instrument easy and quick to apply among adolescents. We emphasize that its application should be preceded by the clarification on the concept of functional foods in order to ensure the adequacy of the answers. Conclusion: This study has demonstrated the adequacy of the Attitudes Towards Functional Foods Scale to assess Portuguese adolescents’ perception regarding functional foods, highlighting the need of using its adapted version.

Eating behaviour is of particular interest for research focusing on body weight status. However, little is known about the relationships of certain factors, especially social desirability, with self-reported eating behaviour such as cognitive restraint, uncontrolled eating, and emotional eating among young adult males and females. This study aimed to evaluate the relationships between eating behaviour and age, socioeconomic status (SES), physical activity (PA), body mass index (BMI), waist-to-height ratio (WHtR), and social desirability among university students. A cross-sectional study was conducted among 353 university students (59.2% females). Eating behaviour was assessed using the 13-item Three-Factor Eating Questionnaire (TFEQ-13). SES and PA were determined using self-reporting, and the Marlowe–Crowne Social Desirability Scale assessed social desirability. BMI and WHtR were calculated based on measured parameters. Associations between self-reported eating behaviour and other variables were assessed using Pearson’s correlation coefficient and multivariate general linear models. Cognitive restraint was positively correlated with BMI and WHtR in both males (r = 0.174, P = 0.036 and r = 0.194, P = 0.020, respectively) and females (r = 0.239, P < 0.001 and r = 0.165, P = 0.017, respectively), and emotional eating was positively correlated with BMI among females (r = 0.184, P = 0.008). Social desirability was negatively correlated with uncontrolled eating (r = −0.287, P < 0.001) and emotional eating (r = −0.301, P < 0.001) among females. There were no significant correlations between eating behaviour and age or socioeconomic status (P > 0.05). Multivariate analysis showed that, among males, PA had a main effect on emotional eating (ηp2 = 0.044, F = 6.276, P = 0.013). Among females, cognitive restraint was positively associated with PA (ηp2 = 0.034, F = 7.127, P = 0.008) and BMI (ηp2 = 0.038, F = 7.959, P = 0.005), and emotional eating with BMI (ηp2 = 0.032, F = 6.638, P = 0.011). Social desirability had the highest main effect on eating behaviour among females, being negatively associated with uncontrolled eating (ηp2 = 0.077, F = 16.754, P < 0.001) and emotional eating (ηp2 = 0.082, F = 18.046, P < 0.001). This study showed that PA, BMI, WHtR, and social desirability were associated with self-reported eating behaviour among university students. Social desirability bias should be considered when evaluating uncontrolled eating and emotional eating among females.

To develop a model of the psychological factors which predict people's intention to adopt personalised nutrition. Potential determinants of adoption included perceived risk and benefit, perceived self-efficacy, internal locus of control and health commitment.A questionnaire, developed from exploratory study data and the existing theoretical literature, and including validated psychological scales was administered to N=9381 participants from 9 European countries (Germany, Greece, Ireland, Poland, Portugal, Spain, the Netherlands, the UK, and Norway).Structural equation modelling indicated that the greater participants' perceived benefits to be associated with personalised nutrition, the more positive their attitudes were towards personalised nutrition, and the greater their intention to adopt it. Higher levels of nutrition self-efficacy were related to more positive attitudes towards, and a greater expressed intention to adopt, personalised nutrition. Other constructs positively impacting attitudes towards personalised nutrition included more positive perceptions of the efficacy of regulatory control to protect consumers (e.g. in relation to personal data protection), higher self-reported internal health locus of control, and health commitment. Although higher perceived risk had a negative relationship with attitude and an inverse relationship with perceived benefit, its effects on attitude and intention to adopt personalised nutrition was less influential than perceived benefit. The model was stable across the different European countries, suggesting that psychological factors determining adoption of personalised nutrition have generic applicability across different European countries.The results suggest that transparent provision of information about potential benefits, and protection of consumers' personal data is important for adoption, delivery of public health benefits, and commercialisation of personalised nutrition.

Gender bias consists in different practices for men and women. It has been suggested that gender biases in medicine occur at various levels, reflected in the way gender issues are included in medical curricula, equity between sexes in academic course and professional career, research and scientific publications, definition of pathologies, clinical practice and health policies. A review of the literature about gender bias in medicine was carried out, particularly in terms of research and clinical practice. The available evidence on this phenomenon and its effects is discussed, and proposals to its reduction are presented. There is a large body of scientific evidence on the existence of gender biases in medicine, leading mostly to greater inadequacy of clinical care provided to female patients. The proposals of several authors may contribute to the reduction of these effects and, consequently, to greater acuity of research and better adequacy of health care. In addition to the larger study of gender bias, we emphasize social, political and educational measures, the regard of participants' sex in the design of clinical trials and the inclusion of the study of gender theories and discussion of attitudes about gender in academic curricula.

There are several barriers related to the non-accomplishment of the dietary treatment of overweight. Social desirability (SD), defined as the tendency to transmit a culturally accepted image, may bias parameters evaluated in scientific studies.(1) To evaluate SD in overweight women; (2) To evaluate the association between SD and other characteristics; (3) To compare the level of SD between patients evaluated in their first appointment or in subsequent appointments; (4) To evaluate the differences in the level of SD between patients who mention or not each barrier to the accomplishment of the dietary treatment; (5) To evaluate the effect of SD in the frequency of each statement pointed out as a barrier to the accomplishment of the dietary treatment.Sixty-seven women with BMI over 25,0 kg/m2 (mean BMI = 40,0 kg/m2; sd= 5,7) and mean age of 40 years (sd = 11) were evaluated on age, education, height, present and desired weights, perception of heath condition, weight and body image (Likert scale from 1 feels very well to 5 very bad). BMI, weight they desired to loose and corresponding BMI were calculated. The number of previous appointments and the date of the first appointment were registered and the time since the first appointment was calculated. Psychopathologic characteristics were studied with the Psychological General Well-Being Index. Barriers to the accomplishment of the dietary treatment were evaluated by pointing, from a list of 34 sentences mentioning obstacles to its accomplishment, those which patients identified themselves with. SD was evaluated with the Marlowe-Crowne Social Desirability Scale (MC-SDS).Mean score on the MC-SDS was 20,9 (sd = 4,0). Positive and weak correlations were found between SD and the number of previous appointments and time since the first appointment. Patients with previous appointments show significantly higher levels of SD than those who were evaluated in their first appointment (means of 21,7 and 18,8; p = 0,005). There weren't found significant differences on the level of SD of patients who pointed or not each sentence and it wasn't found a significant effect of SD in the frequency of any sentence.The mean score on the MC-SDS was higher than values found in the majority of studies, which may result from the higher age, lower education and the presence of pathology. Previous contact with the patients seems to influence SD and may bias and make difficult the interpretation of parameters measured by self-report. The identification of barriers to the accomplishment of the dietary treatment seems to be independent from SD.

The metabolic syndrome (MS) consists of the conjoint presence of risk factors for coronary. Several study groups have developed diagnostic criteria for MS, standing out those from the "Adult Treatment Panel III" (ATPIII), due to their wide utilization. Recently, the International Diabetes Federation (IDF) developed new diagnostic criteria for MS.To evaluate the prevalence of MS in a group of women with severe obesity. To evaluate the prevalence of each one of the diagnostic criteria for MS. To compare the results obtained with the utilization of the ATPIII and the IDF criteria. To relate the results with the patients' age and Body Mass Index (BMI).We evaluated 128 women (mean age = 38 years, sd = 11) with BMI equal to or higher than 35.0 kg/m2 (mean BMI = 46.5 kg/m2, sd = 6.5) on anthropometric measures (weight, height and waist circumference), analytically (fasting serum levels of triglycerides, HDL cholesterol and glucose), being also registered the values of systolic and diastolic blood pressure and age.The prevalence of MS in our sample following the ATPIII and the IDF criteria was, respectively, of 66.4% e 70.3%. The most frequently filled in criteria are those referring to waist circumference (ATPIII: 99.2%; IDF: 100%), blood pressure (77.3%) and HDL cholesterol (69.5%). Older patients and those with higher BMI fill in more criteria, being the diagnostic of MS associated to higher mean age and BMI.The prevalence of MS in women with severe obesity is high, being similar when the ATPIII or the IDF diagnostic criteria are used.
