Modulation of Gut Microbiota Through Dietary Intervention in Neuroinflammation and Alzheimer's and Parkinson's Diseases.

PURPOSE OF REVIEW: The gut microbiota plays a crucial role in the pathogenesis of neuroinflammation and Alzheimer's and Parkinson's diseases. One of the main modulators of the gut microbiota is the diet, which directly influences host homeostasis and biological processes. Some dietary patterns can affect neurodegenerative diseases' progression through gut microbiota composition, gut permeability, and the synthesis and secretion of microbial-derived neurotrophic factors and neurotransmitters. This comprehensive review critically assesses existing studies investigating the impact of dietary interventions on the modulation of the microbiota in relation to neurodegenerative diseases and neuroinflammation. RECENT FINDINGS: There are limited studies on the effects of specific diets, such as the ketogenic diet, Mediterranean diet, vegetarian diet, and Western diet, on the progression of neuroinflammation and Alzheimer's and Parkinson's diseases through the gut-brain axis. The ketogenic diet displays promising potential in ameliorating the clinical trajectory of mild cognitive impairment and Alzheimer's disease. However, conflicting outcomes were observed among various studies, highlighting the need to consider diverse types of ketogenic diets and their respective effects on clinical outcomes and gut microbiota composition. Vegetarian and Mediterranean diets, known for their anti-inflammatory properties, can be effective against Parkinson's disease, which is related to inflammation in the gut environment. On the other hand, the westernization of dietary patterns was associated with reduced gut microbial diversity and metabolites, which ultimately contributed to the development of neuroinflammation and cognitive impairment. Various studies examining the impact of dietary interventions on the gut-brain axis with regard to neuroinflammation and Alzheimer's and Parkinson's diseases are thoroughly reviewed in this article. A strong mechanistic explanation is required to fully understand the complex interactions between various dietary patterns, gut microbiota, and microbial metabolites and the effects these interactions have on cognitive function and the progression of these diseases.

Adherence to the Planetary Health Diet and Its Association with Diet Quality in the Young Adult Population of Türkiye: A Large Cross-Sectional Study.

To advance both human health and environmental sustainability, it's crucial to assess the adaptation to new dietary trends emerging in this field. This study aimed to explore the relationship between diet quality and the principles of planetary health diet in young adults studying at university. This cross-sectional study consisted of 945 young adults with a mean age of 20.1 ± 1.34 y (582 females, 363 males). A questionnaire form containing socio-demographic information (age, gender, education level), anthropometric measurements (body weight and height), and a 24 h dietary record form for three consecutive days was applied. The scores of the Planetary Health Diet Index (PHDI) and the Healthy Eating Index-2020 (HEI-2020) were calculated according to the dietary records. The mean total scores of the PHDI and HEI-2020 were 59.9 ± 14.16 and 54.2 ± 10.87, respectively. The association between the HEI-2020 score and the PHDI score was significant (p = 0.003). A one-unit increase in the unadjusted HEI-2020 score caused a 0.429 unit decrease in the PHDI score (95% CI: -0.709; -0.149). The findings underscore the imperative for targeted interventions and educational programs to enhance the PHDI and HEI-2020 scores, promoting individual well-being and environmental sustainability in the university.

An Overview of the Potential Role of Nutrition in Mental Disorders in the Light of Advances in Nutripsychiatry.

PURPOSE OF REVIEW: As research on the potential impact of nutrition on mental disorders, a significant component of global disability continues to grow the concepts of "nutritional psychiatry, psycho-dietetics/nutripsychiatry" have taken their place in the literature. This review is a comprehensive examination of the literature on the the potential mechanisms between common mental disorders and nutrition and evaluates the effectiveness of dietary interventions. RECENT FINDINGS: Inflammation, oxidative stress, intestinal microbiota, mitochondrial dysfunction, and neural plasticity are shown as potential mechanisms in the relationship between mental disorders and nutrition. As a matter of fact, neurotrophic factors, which make important contributions to repair mechanisms throughout life, and neuronal plasticity, which plays a role in mental disorders, are affected by nutritional factors. In metabolism, the antioxidant defense system works with nutritional cofactors and phytochemicals. A balanced, planned diet that provides these components is more likely to provide nutrients that increase resilience against the pathogenesis of mental disorders. Nutrition can be considered a risk factor for mental disorders. Therefore, developing public health strategies focused on improving diet may help reduce the global burden of mental disorders and other related diseases.

Rise and shine for eating right: the link between healthy nutrition and chronotype among young adults.

Aim: Many studies have examined the relationship between chronotype and general health. Because healthy eating is the basis of health aim of this study is to evaluate the relationship between healthy nutrition attitudes and chronotype in young adults. Methods: This cross-sectional study was conducted with 1,400 young adults (936 females and 464 males). Chronotype was assessed by the Turkish version of the Morningness-Eveningness Questionnaire (MEQ) and the Attitude Scale for Healthy Nutrition (ASHN) was applied by face-to-face interview. Furthermore, 24-h dietary recall was collected. The scores of nutrient adequacy ratio (NAR) and mean adequacy ratio (MAR) were calculated. The anthropometric measurements including body weight and height were taken. Results: The chronotype distribution of participants according to the MEQ score and MAR score were not significantly different between females and males (p > 0.05). The percentage of participants with high healthy eating attitude was lowest in the evening chronotype and highest in the morning chronotype (49.7, 37.7 and 25.4% in morning-, intermediate-, evening-types, respectively; p = 0.000 for all groups according to the reciprocal comparisons). There was a positive correlation of the MEQ scores with the scores of ASHN (r = 0.282, p < 0.01). ASHN score was shown to be a predictor for MEQ score (ß = 0.280, p = 0.000). Moreover, the score of "poor eating habits" was shown to be highest in the evening chronotype and lowest in the morning chronotype (14.9 ± 3.0 and 13.1 ± 3.0, respectively; p < 0.01). Conclusion: The results of this study indicate that individuals with the evening chronotype are more deficient in terms of healthy nutrition attitudes. Further studies with larger populations will potentially guide the development of health promotion strategies to prevent and treat chronic diseases based on an individual's chronotype.

Determinants of disordered eating behaviors: Body mass index, emotional eating, dietary restriction, and motives for eating palatable foods / Determinantes de comportamentos alimentares desordenados: índice de massa corporal, alimentação emocional, restrição alimentar e motivos para comer alimentos palatáveis

ABSTRACT Objective: The study aimed to investigate the relationships between body mass index, reasons for consuming palatable foods, emotional eating, cognitive dietary restraint, and disordered eating behaviors in young adults. Methods: This study was conducted with 800 young adults, in Ankara, Türkiye. A questionnaire consisting of questions about socio-demographic characteristics, health status, and instruments including Eating Attitudes Test-26, Emotional Appetite Questionnaire, Palatable Eating Motives Scale, and The Three-Factor Eating Questionnaire were applied through face-to-face interviews. Results: According to the Eating Attitudes Test-26, 17.2% of males and 27.7% of females were at risk for disordered eating behaviors (χ2=9.750, p=0.002). The mean scores of the Three-Factor Eating Questionnaire-emotional eating, cognitive restraint subscales, and the positive and negative scores of the Emotional Appetite Questionnaire were higher in males than in females (p<0.05). The mean scores of the Palatable Eating Motives Scale-coping and reward enhancement motives were higher in females, while the mean score for the conformity motives was significantly higher in males. Body mass index, Three-Factor Eating Questionnaire-cognitive restraint subscale, Emotional Appetite Questionnaire-negative, and PEMS-conformity motives were found for predictors for Eating Attitudes Test-26 (all p<0.05). Conclusion: The results showed a high tendency for emotional eating, consumption of palatable foods, and cognitive dietary restraint in young adults, and these factors were considered determinants for eating disorders.

RESUMO Objetivo: O objetivo do estudo foi investigar as relações entre o índice de massa corporal, as razões para consumir alimentos palatáveis, o comer emocional, a restrição alimentar cognitiva e os comportamentos de desordem alimentar em jovens adultos. Métodos: Este estudo foi realizado com 800 jovens adultos, em Ancara, na Turquia. Foi aplicado um questionário composto por perguntas sobre características sociodemográficas, estado de saúde e instrumentos, incluindo o Eating Attitudes Test-26, o Emotional Appetite Questionnaire, a Palatable Eating Motives Scale e o The Three-Fator Eating Questionnaire, através de entrevistas presenciais. Resultados: De acordo com o Eating Attitudes Test-26, 17,2% dos homens e 27,7% das mulheres estavam em risco de desenvolver comportamentos alimentares desordenados (χ2=9,750, p=0,002). As pontuações médias do Three-Fator Eating Questionnaire-emotional eating, as subescalas de restrição cognitiva e as pontuações positivas e negativas do Emotional Appetite Questionnaire foram mais elevadas no sexo masculino do que no feminino (p<0,05). As pontuações médias da Palatable Eating Motives Scale - motivos de coping e de aumento da recompensa - foram mais elevadas no sexo feminino, enquanto a pontuação média para os motivos de conformidade foi significativamente mais elevada no sexo masculino. O índice de massa corporal, o Three-Fator Eating Questionnaire-subescala de contenção cognitiva, o Emotional Appetite Questionnaire-negativo e o PEMS-motores de conformidade foram encontrados como preditores do Eating Attitudes Test-26 (todos p<0,05). Conclusão: Os resultados mostraram uma elevada tendência para a alimentação emocional, o consumo de alimentos palatáveis e a restrição alimentar cognitiva em adultos jovens, sendo estes factores considerados determinantes para as perturbações alimentares.

Validity and Reliability of the Turkish Version of the Sustainable and Healthy Eating Behaviors Scale.

This study was conducted to determine the validity and reliability of the Turkish version of the Sustainable and Healthy Eating (SHE) Behaviors Scale. The original scale included 8 factors and 34 items related to the SHE behaviors of adults. The research was carried out in three stages with a total of 586 participants aged 19 to 50 years. The Cronbach alpha coefficient was used to evaluate internal consistency reliability and the test-retest method was applied. Exploratory factor analysis (EFA) was performed to determine the factor structure. The model obtained with EFA was evaluated with confirmatory factor analysis (CFA). The Cronbach alpha coefficient of the scale was found to be excellent at 0.912, and the intra-class correlation coefficient was found to be good at 0.832 using the test-retest method. Considering the suitability of the data for factor analysis, the KMO coefficient was 0.859, and the significance level of the Bartlett test of sphericity was less than 0.05 (χ2=3.803,25; p<0.05). As a result of EFA, the items of the scale were found to be distributed in 7 factor dimensions. The factor loadings of the items were between 0.516 and 0.890, and the factors explained 67% of the variance. Considering the fit indices obtained as a result of the analysis of this model with CFA, it was seen that the model had an acceptable fit (χ2/sd=2.593, CFI=0.915, Tucker-Lewis index=0.902, SRMR=0.0754, and RMSEA=0.067). In conclusion, the Turkish version of the SHE Behaviors Scale has credible reliability and construct validity to assess the sustainable and healthy eating behaviors of the Turkish adult population.

Organic pollutant exposure and health effects of cooking emissions on kitchen staff in food services.

This study was conducted to determine the exposure and health risk to cooking fumes of a total of 88 volunteer kitchen staff aged between 18 and 65 years working in five different kitchens in Ankara. Gas- and particle-phase polycyclic aromatic hydrocarbons (PAHs), and volatile organic compound (VOCs) concentrations were evaluated in the indoor air of 5 kitchens. Serum malondialdehyde (MDA) and superoxide dismutase (SOD) levels were analyzed to determine the oxidative damage as a result of the exposure to cooking fumes among the cooks and waiters. Significant positive relationships were found between serum MDA levels of the hot kitchen workers and indoor chrysene (Chr), indeno(1,2,3-c,d)pyrene (Ind), and total VOC levels. Although the carcinogenic risks estimated for the exposed population were between the acceptable/tolerable levels, the hazard quotient (HQ) estimated for the exposure to indoor benzene exceeded the safe level. The results of the study revealed that exposure to organic pollutants in indoor air may be a risk factor for the development of oxidative stress, especially in hot kitchen workers. The importance of efficient ventilation in the kitchen has been pointed out to reduce health risks caused by cooking fumes.

Changes in intestinal parameters and their association with dietary patterns in rotational shift workers.

Circadian rhythm disturbances induced by rotating shift work contribute to development of metabolic disorders. However, their effects on intestinal parameters such as epithelial permeability and fecal short chain fatty acid (SCFA) levels have not been established yet. This study was planned to investigate the changes in intestinal integrity, fecal SCFA levels, gut microbiota and nutritional intake of rotational shift workers. The study was conducted on ten male rotational shift workers, 25-40 years old. Circadian rhythm disruption was assumed to have occurred after 14 days in the night shift. Dietary data which was obtained by using 24 h record for 7 days, physical activity data, anthropometric measurements, fecal and blood samples were collected during day and night shift. Changes in dietary consumption, anthropometric measurements, blood chemistry and intestinal epithelial permeability indicator according to day and night shifts were not significant (p > .05). Additionally, acetic, propionic and total SCFA were associated with the intestinal permeability biomarker in night shift, but not in day shift (p < .05). Consumption of dark green vegetables and beans and peas was positively associated with fecal isobutyric acid and fecal total SCFA concentration (r = 0.685, p = .029; r = 0.695, p = .026, respectively). The proportions of the genus including Blautia, Bifidobacterium, Dialister, and Ruminococcus gnavus group increased when individuals shifted to the night shift. Gut microbiota changes responding to circadian rhythm disruption became more prominent when consumed high sugar diet. So, changes have been observed in the gut microbiota of rotational shift workers, especially in individuals with certain dietary pattern. Moreover, in individuals with the circadian rhythm disruption SCFAs levels have been demonstrated to be associated with intestinal barrier integrity. A better understanding of the relation among fecal SCFAs, gut microbiota, intestinal epithelial permeability and circadian rhythm disruption is necessary for the development of new dietary strategies for gut health.

The relationship between the risk of eating disorder and meal patterns in University students.

PURPOSE: This study was carried out to evaluate the relation between meal patterns and the risk of eating disorders in university students. METHODS: The study was conducted on a total of 331 volunteer students with a mean age of 22.08 ± 1.80 years, 56.5% female. Participants' sociodemographic characteristics, health information and eating habits like meal skipping and dieting were questioned. Sick, Control, One stone, Fat, Food (SCOFF) Eating Disorders Scale and Eating Disorder Examination Questionnaire (EDE-Q) were used to determine eating behavior disorders, with face to face interviews by the researches. RESULTS: A significant correlation was found between dieting and skipping meals and the risk of eating disorders in both genders (p < 0.05). In addition, when the reasons for skipping meals were questioned, a significant relationship was detected between skipping meals and eating behaviour disorders by 3.285 times (p = 0.000). Also, every unit of increase in body mass index (BMI) values of individuals who participated to the study led to an increase in eating disorders by a factor of 1.262 (p = 0.000). CONCLUSIONS: Our findings support concerns about the negative health effects of increasing overweight among university students in accordance with the data that the increase in BMI values led to an increase in eating disorders. Notably a significant correlation was found between dieting, skipping meals and the risk of eating disorders in both genders it is highlighting the need for monitoring and early diagnosis of eating disorders in youth with simple scales like SCOFF. LEVEL OF EVIDENCE: Level V, cross-sectional descriptive study.

Gut-Brain-Microbiota Axis: Antibiotics and Functional Gastrointestinal Disorders.

Gut microbiota composition and function are major areas of research for functional gastrointestinal disorders. There is a connection between gastrointestinal tract and central nervous system and this is mediated by neurotransmitters, inflammatory cytokines, the vagus nerve and the hypothalamic-pituitary-adrenal axis. Functional gastrointestinal disorders are prevalent diseases affecting more than one third of the population. The etiology of these disorders is not clarified. Visceral hyperalgesia is the main hypothesis for explaining clinical symptoms, however gut-brain axis disorder is a new terminology for functional disorders. In this review, microbiota-gut-brain axis connection pathways and related disorders are discussed. Antibiotics are widely used in developed countries and recent evidence indicates antibiotic-induced dysbiosis as an important factor for functional disorders. Antibiotics exert negative effects on gut microbiota composition and functions. Antibiotic-induced dysbiosis is a major factor for occurrence of post-infectious irritable bowel syndrome. Cognitive and mood disorders are also frequent in functional gastrointestinal disorders. Animal and human trials show strong evidence for the causal relationship between gut microbiota and brain functions. Therapeutic implications of these newly defined pathogenic pathways are also discussed.

Are anthropometric measurements an indicator of intuitive and mindful eating?

PURPOSE: Intuitive eating and mindful eating are new approach eating behaviors. Assessing the relationship of some anthropometric measurements to intuitive eating and mindful eating. METHODS: Cross-sectional descriptive study. Adults aged 19-45 living in the center of Ankara the capital of Turkey. 250 volunteers (68 men and 182 women) aged 19-45 years. Data were collected through face-to-face interviews using a questionnaire contained the Intuitive Eating Scale (IES-2), Mindful Eating Questionnaire (MEQ-30) and Eating Attitudes Test (EAT-26). Anthropometric measurements were performed by the researchers themselves. Between-group analyses were performed to test statistical differences and relationships. RESULTS: There was a positive correlation between IES-2 and MEQ-30 scores (r = 0.477; p = 0.000), indicating that the higher the IES-2 scores, the higher the MEQ-30 scores. IES-2 scores and BMI were negatively correlated (p < 0.05) and also MEQ-30 scores were negatively correlated with waist-to-height ratio and BMI (r = - 0.143; p = 0.024, r = - 0.159; p = 0.012). The higher the "disinhibition" and "control of eating," the lower the body weight, waist circumference, waist-to-height ratio and BMI was found. CONCLUSIONS: It was concluded that the more the intuitive eating, the more the mindful eating. And also it is suggested that anthropometric measurements might be an indicator of intuitive eating and mindful eating. LEVEL OF EVIDENCE: Level V, cross-sectional descriptive study.

The circadian disruption of night work alters gut microbiota consistent with elevated risk for future metabolic and gastrointestinal pathology.

Day and night cycles are the most important cue for the central clock of human beings, and they are also important for the gut clock. The aim of the study is to determine the differences in the gut microbiota of rotational shift workers when working the day versus night shift. Fecal samples and other data were collected from 10 volunteer male security officers after 4 weeks of day shift work (07:00-15:00 h) and also after 2 weeks of night shift work (23:00-07:00 h). In total, 20 stool samples were collected for analysis of gut microbiota (10 subjects x 2 work shifts) and stored at -80°C until analysis by 16 S rRNA sequencing. The relative abundances of Bacteroidetes were reduced and those of Actinobacteria and Firmicutes increased when working the night compared to day shift. Faecalibacterium abundance was found to be a biomarker of the day shift work. Dorea longicatena and Dorea formicigenerans were significantly more abundant in individuals when working the night shift. Rotational day and night shift work causes circadian rhythm disturbance with an associated alteration in the abundances of gut microbiota, leading to the concern that such induced alteration of gut microbiota may at least partially contribute to an increased risk of future metabolic syndrome and gastrointestinal pathology.

Factors affecting emotional eating and eating palatable food in adults.

BACKGROUND/OBJECTIVES: The aim of this study was to determine the relationship among emotional eating behavior, tendency to eat palatable foods, and several risk factors. SUBJECTS/METHODS: This study was carried out on 2,434 persons (1,736 women and 698 men) aged between 19 and 64 years. A questionnaire form was used as a data collection tool, which consisted of items for the socio-demographic characteristics, anthropometric measurements, Emotional Appetite Questionnaire (EMAQ), and the Palatable Eating Motives Scale (PEMS). RESULTS: A positive significant correlation was observed between the BMI groups and the negative emotions, negative situations, and negative total scores of EMAQ (P < 0.01). The regression results on negative subscales showed that a one unit increase in BMI resulted in a 0.293 unit increase in negative situations scores, a 0.626 unit increase in negative emotions scores, and a 0.919 unit increase in negative total EMAQ scores. When the BMI groups and PEMS subscale scores were examined, a significant relationship was found in the social motives, rewarding, and conformity subscales (P < 0.01). A one unit increase in BMI increased the coping motives scores by 0.077 units. CONCLUSIONS: The emotional states have a significant effect on the eating behavior. On the other hand, an increase in eating attacks was observed, particularly in people who were under the effect of a negative emotion or situation. Nevertheless, there were some limitations of the study in terms of quantitative determination of the effects of this eating behavior depending on the BMI.

Intuitive eating in youth: Its relationship with nutritional status / Alimentação intuitiva na juventude: sua relação com o estado nutricional

ABSTRACT Objective To determine intuitive eating in young adults and the effects of factors such as gender, Body Mass Index and dietary intake, and dietary adequacy on intuitive eating. Methods This cross-sectional study was conducted with students at Gazi University in Ankara (N=665; 17.6% men; 82.4% women). The questionnaire, including the general characteristics, anthropometric measurements, Intuitive Eating Scale-2, and 24-H Dietary Recall sections, were applied to all participants. For the evaluation of the diet, Nutrient Adequacy Ratio and Mean Adequacy Ratio were used. Results The mean Intuitive Eating Scale-2 score was 3.2±0.33; men's and women's scores were 3.3±0.37 and 3.2±0.32, respectively (p<0.05). According to linear regression analysis, gender, age and mean adequacy ratio had an effect on the model for the score (p<0.05). In addition, there was a negative correlation between Intuitive Eating Scale-2 scores and Body Mass Index values in women (rp=-0.095, p=0.026). Conclusion The intuitive eating scores varied according to gender, dietary adequacy and age. Intuitive eating may be effective in the formation of long-term behavioral changes, which is beneficial for the treatment of obesity. The result of this study may encourage the development of this behavior in groups (may vary according to gender), that is thought to be effective by considering the changes of intuitive eating behavior.

RESUMO Objetivo Determinar a alimentação intuitiva em adultos jovens e os efeitos de fatores como sexo, índice de massa corporal, ingestão alimentar e adequação da dieta na alimentação intuitiva. Métodos Este estudo transversal foi realizado em estudantes da Universidade de Gazi, em Ancara (N=665; 17,6% homens; 82,4% mulheres). O questionário, incluindo as características gerais, medidas antropométricas, Escala de Alimentação Intuitiva 2 e recordatório alimentar de 24 horas foi aplicado aos participantes. Para a avaliação da dieta, foram utilizados o Índice de Adequação de Nutrientes e a Razão de Adequação Média. Resultados A Escala Média de Escala de Comportamento Intuitivo-2 foi de 3,2±0,33, dos homens e das mulheres, foi de 3,3±0,37 e 3,2±0,32, respectivamente (p<0,05). De acordo com a análise de regressão linear, sexo, idade a Razão de Adequação Média tiveram efeito no modelo formado pelo escore (p<0,05). Além disso, houve uma correlação negativa entre os escores da Escala de Alimentação Intuitiva-2 e os valores do índice de massa corporal nas mulheres (rp=-0,095, p=0,026). Conclusão Os escores alimentares intuitivos variaram de acordo com o gênero, com adequação da dieta e com a idade. A alimentação intuitiva pode ser eficaz na formação de mudanças a longo prazo no comportamento, o que é benéfico para o tratamento da obesidade. O resultado deste estudo pode encorajar o desenvolvimento deste comportamento em grupos (talvez variar de acordo com o gênero) que é considerado efetivo considerando-se as mudanças do comportamento alimentar intuitivo.

Assessment of the Contribution of Dietary and Beverage Intake Quality to Obesity Development.

OBJECTIVE: Low dietary quality is an important indicator of unhealthy eating patterns that can lead to some consequences such as obesity, so policy is a very powerful tool that can affect the consumption of both healthy and unhealthy foods. Indices that assess whether nutritional policies are applied contribute to the assessment of the quality of the population's diet. This study was conducted to investigate the quality of diets and beverages consumed by Turkish adults, and the factors affecting them. METHOD: This cross-sectional descriptive study was conducted on 352 adults aged between 18 and 58 years. The quality of diet and beverage was measured through the Healthy Eating Index-2010 (HEI) and Healthy Beverage Index (HBI), respectively, using 2-day (weekday and weekend) dietary recall data. RESULTS: The total HBI scores were 79.1 ± 11.8 and 81.0 ± 11.6; total HEI-2010 scores were 45.9 ± 12.3 and 52.3 ± 11.0, of men and women, respectively (p < 0.05). The women had significantly higher scores than that of the men in the HEI-2010 subcomponent of empty calories (p > 0.05). Sugar-sweetened beverage (HBI subcomponent) was significantly correlated with the scores of HEI-2010 and empty calorie (HEI-2010 subcomponent), as expected (p < 0.01). The caloric beverages contributed ∼133.6 kcal/d to the total caloric intake. CONCLUSIONS: The mean contribution of beverages to total daily energy intake of participants was found to be at the suggestion level. This result is rewarding when the relationship of sugar-sweetened beverages scores with the scores of HEI and empty calories is considered.

Os dados do estudo foram coletados com o auxílio de um questionário com um registro alimentar de três dias. Resultados: A ingestão de energia diária média do grupo de estudo foi maior que a mesma ingestão do grupo controle (1756±659 kcal versus 1694±431 kcal, p>0,05). Enquanto que as ingestões de carboidratos (196,3±85,5 g versus 185,9±54,7 g) e lipídeos (79,5±29,5 g versus 77,1±22,6 g) foram maiores no grupo de estudo, a ingestão de proteínas foi maior no grupo controle (59,4±17,6 g versus 57,6±21,6 g). A ingestão média de ferro foi estatisticamente maior no grupo controle (10,6±2,9 mg versus 10,0±4,0 mg, p<0,05). Conclusão: Para melhorar o desempenho e estado nutricional de enfermeiras que trabalham no turno da noite é importante disponibilizar unidades de alimentação e nutrição saudáveis, acessíveis, e de qualidade.

Does the rise in eating disorders lead to increasing risk of orthorexia nervosa? Correlations with gender, education, and body mass index.

Investigating eating disorders and orthorexia nervosa, especially in the young population, is an important step in taking protective precautions and identifying disease. This study was carried out to determine the relationship of eating disorders and orthorexia nervosa to gender, BMI, and field of study in a population of university students in Turkey. In all, 900 university students aged 17-23 years participated in this study. EAT-40 and ORTO-15, which are validated instruments for the screening of participants with anormal eating behaviors and orthorexia nervosa, respectively, were used. There was not a significant difference in EAT-40 scores according to gender and BMI classification. However, EAT-40 scores were high among the students in social science. The number of orthorectic participants among women is higher than that among men, and ORTO-15 scores were not associated with BMI classification and field of study. A significant negative correlation was found between EAT-40 and ORTO-15 scores.

Energy expenditure and nutritional status of coal miners: A cross-sectional study.

The objectives of this study were to assess the nutritional status, daily energy intake, and daily energy expenditure of coal miners in Turkey. A total of 135 healthy coal miners (aged 19-64 years) were evaluated. Heart rates were measured using Polar watches, and the total energy expenditure was calculated using physical activity level formula and Hiilloskorpi equation. The average body mass index of the participants was 25.7 ± 3.98 kg/m2, and the average energy intake was 3,973.7 ± 420.85 kcal. According to Dietary Reference Intakes, the energy and nutrient intakes of the miners were adequate, except for the intake of vitamin D. The coal miners were found to be at moderate (43.0%), heavy (41.5%), and very heavy (13.3%) activity levels. Calculations of the energy expenditure at work were found to be 2,189.8 ± 376.19 to 2,788.8 ± 359.89 kcal per day. Further studies have to be conducted for developing national standards for each occupation.

Comparison of energy balance-related behaviours and measures of body composition between Turkish adolescents in Turkey and Turkish immigrant adolescents in the Netherlands.

OBJECTIVE: To explore the influences of migration to a Western country on obesity and related risk factors by comparing measures of body composition and energy balance-related behaviours between Turkish adolescents in Turkey (TR-TR) and adolescents from Turkish immigrant ethnicity in the Netherlands (TR-NL). DESIGN: Cross-sectional survey or baseline intervention data from six Dutch school-based studies and one Turkish study. SETTING: Primary and secondary schools. SUBJECTS: A total of 915 (49 % girls; mean age 13·1 (sd 0·8) years) TR-TR adolescents and 433 (51 % girls; mean age 11·7 (sd 1·3) years) TR-NL adolescents were included. Outcome measures were self-reported sugar-containing beverage consumption, fruit and vegetable intake, screen time, physical activity, measured body height and weight, BMI, waist and hip circumferences, and skinfold thicknesses. RESULTS: Our data showed that more TR-NL adolescents were overweight (31 % v. 26 %) and obese (9 % v. 6 %) and had significantly higher mean BMI (21·1 v. 20·0 kg/m2), waist circumference (72·2 v. 71·3 cm) and suprailiac skinfold thickness (19·8 v. 13·1 mm) than TR-TR adolescents. TR-NL adolescents reported significantly higher sugar-containing beverage consumption (1173 v. 115 ml/d), less fruit and vegetable intake (295 v. 647 g/d), less screen time (253 v. 467 min/d) and higher physical activity levels (61 v. 27 min/d) than TR-TR adolescents. CONCLUSIONS: Immigrant adolescents in the Netherlands were more often overweight and had a less favourable dietary pattern than their peers in Turkey, while their physical activity and screen time patterns were more favourable. These results suggest that adolescents from Turkish immigrant ethnicity in the Netherlands have adopted lifestyles towards the host culture.

Relationship between dietary mineral intake and blood pressure (BP) in the elderly in Turkey.

The aim of this study was to determine the relationship between daily dietary mineral (Na, K, Ca and Mg) intake and BP in the elderly. This study was conducted on 390 elderly volunteers (≥ 65 years). Subjects were randomly selected from the general population of Ankara, Turkey. Anthropometric measurements, lipid profiles, and mean systolic and diastolic BP (SBP and DBP) of all the participants were measured. To determine the mineral intake of the participants, food consumption was measured with a 24-h dietary recall. The 49.3% of participants were found to be hypertensive, 25.1% to be pre-hypertensive and 25.6% were normotensive according to the JNC-7 Guidelines, except for daily Mg and Na intake, the energy, macronutrient and micronutrient intake of groups were not significantly different (p>0.05). A significant inverse correlation between daily Ca intake and SBP was found in the pre-hypertensive group when age and gender adjusted regression analyses were performed (B=-0.006, p<0.05). Na intake and Na/K ratio were directly associated with SBP in the hypertensive group. In conclusion, SBP was found to be most related to dietary Na and Ca intake, and Na-to-K ratio in the elderly population.
