Yılmaz, Hacı Ömer; Meriç, Çağdaş Salih; Yabancı Ayhan, Nurcan
The aim of the study was to compare the effects of acute intake dietary sugars on cognitive performance and reaction time. This study was, randomized, placebo-controlled, double-blind experimental design, conducted with 75 healthy adults. At the beginning of the study, the participants (36 male, 39 female; 21.6 ± 1.3 years of age; body mass index: 21.59 ± 1.94 kg/m2) were randomly divided into equal five groups (n:15) (glucose (10 g), fructose (10 g), sucrose (10 g), saccharin (0.24 g), placebo), and received dietary sugars dissolved in 200 mL of water. Cognitive performance was determined with Cancelation Test, and the Simple Response Time and Ruler Drop Tests were used in order to response and reaction time of participants, respectively. General score of cognitive performance (0.93 ± 0.1), reaction (295 ± 20 ms), and response (204 ms) were highest in glucose and lowest in placebo (0.63 ± 0.1; 368 ± 22 ms; 251 ms, respectively) (p <.001). Saccharin groups had a higher reaction (312 ± 22 ms) and response (216 ms) time score compared to consumed fructose (316 ± 39; 227 ms), sucrose (354 ± 26; 246 ms), and placebo (368 ± 22; 251 ms) groups, respectively (p <.001). These findings show that differences in the absorption pattern and sweetness levels of sugar types may have different effects on cognitive performance and reaction time.

Objective: Obesity may negatively affect the physical health and cognitive functions of individuals and delay their reaction time to stimuli. However, the association among obesity, cognitive functions, and reaction times is yet to be fully elucidated. The aim of this study was to assess the effect of obesity on cognitive functions and visual and auditory reaction times in adults. Methods: Data of 100 participants (50 obese and 50 normal) were analyzed in the study. Anthropometric parameters and 24-h dietary recall data were recorded. The Montreal Cognitive Assessment (MoCA) was used to evaluate the cognitive functions, Simple Reaction Time Task (SRTT)-Visual and SRTT-Auditory were used to assess visual and auditory reaction times of the participants, respectively. Results: The mean MoCA score of the obese was significantly lower than normal (17.46 and 25.22, respectively; p < 0.001). In addition, the mean auditory (p < 0.001) and visual (p < 0.05) reaction times of obese were significantly longer than normal. Similarly, this condition was also observed for the fastest and lowest values of auditory and visual reaction times. Additionally, obesity caused a decrease in the MoCA score (β = -0.762; p < 0.001) and delayed visual (β = 0.423; p < 0.001) and auditory (β = 0.590; p < 0.001) reactions. The negative effect of obesity was maintained after controlling for potential factors (MoCA, β = -0.594; p < 0.001; SRTT-Auditory, β = 0.409; p < 0.01; SRTT-Visual, β = 0.330; p < 0.05). Conclusion: Obese participants showed worse cognitive, auditory and visual performance. Additional research will be necessary in the future to shed light on the fundamental mechanisms involved.

Türkkan, Tuğba; Bülbül, Kenan; Yılmaz, Hacı Ömer; Meriç, Çağdaş Salih
Giriş ve Amaç: İnternet bağımlılığı özellikle fizyolojik, psikolojik ve sosyal gelişimin hızlı olduğu, başta beslenme olmak üzere çoğu alışkanlıkların kazanıldığı çocukluk ve adölesan dönemi etkilemektedir. Bu araştırma, adölesanlarda internet bağımlılığının beslenme alışkanlıkları ve vücut ağırlığı-obezite (BKİ/Z-Skor) ile ilişkisini değerlendirmek amacıyla planlanmış ve yürütülmüştür. Gereç ve Yöntemler: Tanımlayıcı-kesitsel tipte olan bu araştırmaya basit rastgele örneklem metodu ve yüz yüze görüşme tekniği kullanılarak 679 adölesan dahil edilmiştir. Araştırmacılar tarafından güncel literatürün taranmasıyla hazırlanan anket formu adölesanların sosyo demografik özelliklerini, beslenme alışkanlıklarını, Türkiye Beslenme Rehberi’ne (TÜBER) göre günlük tüketilmesi gereken besin gruplarını, adölesanların fiziksel aktivite düzeylerini, internet ve akıllı telefon kullanım durumları ile “Young İnternet Bağımlılığı Ölçeği–Kısa Form (YİBÖ-KF)”unu içermektedir. Bulgular: Yaş ortalaması 14,06±2,06 yıl olan adölesanların BKİ ve Z-skor ortalamaları sırasıyla 20,67±3,7kg/m2 ve 1,24±1,10’dur. Z-skor’a göre adölesanların %77,0’ı zayıf/normal, %23,0’ı şişman/obez olarak kategorize edilmiştir. Şişman/obez adölesanların zayıf/normal olanlara kıyasla internet ve akıllı telefon kullanım sürelerinin anlamlı olarak yüksektir. Adölesanların YİBÖ-KF puanları 26,2±7,6 olup şişman/obez adölesanların puanları (27,8±7,0) zayıf/normal olanlara kıyasla (25,7±7,7) anlamlı olarak yüksektir. TÜBER’in günlük önerdiği düzeyde süt ve süt ürünleri, ekmek ve tahıl ürünleri ile sebze tüketen adölesanların internet bağımlılık düzeyleri bazen tüketen veya hiç tüketmeyenlere kıyasla anlamlı olarak düşüktür. Adölesanların Z-skorları ile internet bağımlılıkları arasında kuvvetli pozitif korelasyon belirlenmiş olup adölesanların internet bağımlılıkları arttıkça Z-skorları ve obezite riskleri de artmaktadır. Sonuç: Araştırma bulguları adölesanların önemli ölçüde sağlıksız beslenme alışkanlıklarına sahip olduklarını, sağlıklı besin gruplarını günlük önerilen düzeyde tüketmediklerini ve bu durumun internet bağımlılığı ile ilişkili olduğunu göstermiştir. İnternet bağımlılığı ve beslenme alışkanlıkları ile anormal vücut ağırlığı arasındaki ilişkinin objektif ölçümler ile detaylıca irdeleneceği, geniş ölçekli ileriye dönük çalışmalara ihtiyaç vardır.
- MakaleYalnız künye2024Is environment destiny? Spatial analysis of the relationship between geographic factors and obesity in Türkiye
Yılmaz, Hacı Ömer; Günen, Mehmet Akif
This study aims to evaluate the relationship of geographical factors, including precipitation, slope, air pollution and elevation with adult obesity prevalence in Türkiye (TR) using a cross-regional study design. Ordinary least squares (OLS) and geographically weighted regression (GWR) were performed to evaluate the spatial variation in the relationship between all geographic factors and obesity prevalence. In the model, a positive relationship was found between obesity prevalence and slope, whereas a negative significant relationship was determined between obesity prevalence and elevation (p < 0.05). These results, revealing spatially varying associations, were very useful in refining the interpretations of the statistical results on adult obesity. This research suggests that geographical factors should be considered as one of the components of the obesogenic environment. In addition, it is recommended that national and international strategies to overcome obesity should be restructured by taking into account the geographical characteristics of the region.

Bu araştırma, spor salonuna giden bireylerin beslenme alışkanlıkları, beslenme bilgi düzeyi ve besin desteği kullanım durumlarını belirlemek amacıyla planlanmış ve yürütülmüştür. Tanımlayıcı-kesitsel tipte olan araştırmanın verileri anket aracılığıyla elde edilmiştir. Anket formu demografik bilgiler, beslenme alışkanlıkları, Yetişkinler İçin Beslenme Bilgi Düzeyi Ölçeği ve besin desteği kullanımına yönelik sorulardan oluşmaktadır. Araştırmada 360 spor salonuna giden bireye (242 erkek, 118 kadın, ortalama yaş=22,1±5,6 yıl) ait veriler değerlendirilmiştir. Katılımcıların beslenme alışkanlıklarının önerilen düzende olmadığı, %19,4’ünün kötü düzeyde temel beslenme ve %17,5’inin kötü düzeyde besin tercih bilgisi olduğu ve %30,0’ının ise besin desteği kullandığı belirlenmiştir. Spor salonuna giden bireylerin sağlıklı beslenme alışkanlıkları kazanımı ve yüksek beslenme bilgisi edinimine bağlı olarak, daha bilinçli ve doğru şekilde besin desteği kullanım tercihinin olabileceği düşünülmektedir. Bu konuda, özellikle spor ve sporcu beslenmesi alanında uzmanlaşmış diyetisyenler bilgi edinim kaynağı olarak tercih edilebilir. Ayrıca, spor salonuna giden bireylerin beslenme konusunda sıklıkla bilgisine başvurduğu salon antrönerlerinin de besinler, besin destekleri ve sporcu beslenmesi ile ilgili bilimsel kaynakları tercih etmesi ve bireyleri daha doğru ve sağlıklı bir şekilde yönlendirmesi önerilmektedir.

Yılmaz, Hacı Ömer; Meriç, Çağdaş Salih
Buckwheat (Fagopyrum esculentum Moench and Fagopyrum tataricum (L.) Gaertn.) is believed to have originated in central Asia. Chiefly cultivated in India, Nepal, China, North Korea, Russia, and Japan, it is a pseudocereal containing high protein, dietary fiber, vitamins and minerals, polyunsaturated fatty acids, and important antioxidants and phenolic compounds. In addition to its high protein bioavailability and economic value, it is an important alternative food with high nutritional value, suitable for the diet of celiac patients because it does not contain gluten. Buckwheat has gained worldwide importance because of the presence of some important bioactive constituents such as rutin, orientin, vitexin, quercetin, isovitexin, and isoorientin; other essential components like fagopyritols find vast potential for glycemic control in type 2 diabetics, positive cardiovascular effects, treatment of celiac disease, prevention of gallstones, and several hormone-dependent tumors. Currently, various products of buckwheat like flour, bread, biscuits, cookies, muffins, cakes, pasta, noodles, crackers, chips, and various fermented products and desserts are available in the market. Buckwheat has attracted worldwide attention, especially from food scientists, for its healing effects over chronic diseases. This chapter focuses on buckwheat in diets of the Middle East and its important effects on health.

Objectives: This study was carried out in order to determine the prevalence of obesity among the students of the Faculty of Health Sciences and to evaluate the anthropometric measurements of the students. Materials and methods: The population of the study was in total 984 volunteering undergraduate students from Ankara University Faculty of Health Sciences, Child Development, Midwifery, Nursing, Health Management and Social Work departments. The sociodemographic characteristics of the students were obtained with the help of the questionnaire and the anthropometric measurements by the researchers. SPSS package program was used for descriptive statistics, chi-square test and multiple logistic regression analysis for assessment of data. Results: 16.5% of the students participating in the study were overweight and 4.5% were obese. Approximately half of the students who are overweight and obese reported staying in the dormitory. Average BMI value in males is 23.1 kg/m2 and 22.3 kg/m2 in females. 29.1% of females are at risk in terms of abdominal obesity and 30.6% of males in terms of waist/height ratio. Male gender and presence of an obese person in the family increases the risk of being overweight or obese. Conclusions: Risky health behaviors are observed among university students and in order to avoid such behaviors, it is necessary to provide training especially on subjects such as nutrition and physical activity. Adopting the right nutritional habits and healthy lifestyle is important in individuals who will be the future healthcare professionals, for both their and future generations' health.
- MakaleYalnız künye2021The Relationship between Body Mass Index and Eating Disorder Risk and Intuitive Eating among Young Adults
Yılmaz, Hacı Ömer; Zemzemoglu, Tuba Eda Arpa
Background: Obesity is a serious health problem that threatens public health. There are limited researches exploring the relationship between obesity and eating disorder risk and intuitive eating. The purpose of this study was to determine the rate of eating disorder risk and obesity, and identify the relationship between body mass index (BMI) and eating disorder risk and intuitive eating among young adults. Methods: This cross-sectional study enrolled 1216 young adults. The data were obtained through a questionnaire consisted of three sections of socio-demographic information in the first part, Intuitive Eating Scale-2 (IES-2) in second part and Eating Attitudes Test-26 (EAT-26) in third part. Weight, height, and BMI of participants were also measured by researchers. Results: The overall overweight/obesity rate of the participants was 16% (male=25.9%; female=10.9%). The rate of eating disorders risk was 24.3% in general (male=21.5%; female=25.4%). Overweight/obese had higher eating disorders risk than normal and underweight (26.7%, 23.8%, 21.6%, respectively). IES-2 score of underweight was significantly higher than overweight/obese (3.33±0.35, 3.20±0.37, respectively). Conclusion: This is the first study to examine the relationship between BMI and EAT-26 subscale showing that BMI was positively correlated with EAT-26 and negatively was correlated with IES-2 score. Therefore, BMI may be affected by eating behaviors and intuitive eating. Also, intuitive eating can be a new method of eating, and weight control and management.

COVID-19 disease, which has spread rapidly all over the world since the first case was detected in December 2019, has become the primary focus in every country. Radical measures have been taken by governments to prevent the spread of the disease. Precautions and social rules have required drastic changes to daily life activities everywhere. University students who have had to interrupt their educations are one of the affected groups by this disease sociologically, psychologically and physiologically. The aim of this study was planned and conducted to determine the effect of COVID-19 on university students' eating habits and food purchasing behaviors. The study was completed in April 2020 with 866 university students studying and training at the Faculty of Health Sciences, Gümüşhane, Turkey. Research data was obtained by online questionnaire. The questionnaire was prepared with information obtained from a literature review and the opinions of experts. It included questions about eating habits and food purchasing behaviors. The basic result of the study was that COVID-19 disease has caused significant changes in the eating habits and food purchasing behaviors of university students. Primarily, they now paid greater attention to hygiene when food purchasing, and had increased their consumption compared to previously, since they were now home 24 hours a day, seven days a week.
- MakaleAçık Erişim2019Is there prejudice against obese persons among health professionals? A sample of student nurses and registered nurses
Yılmaz, Hacı Ömer; Yabancı Ayhan, Nurcan
Purpose: The aim of this study was to assess whether there is prejudice toward obese persons among student nurses and registered nurses. Design and Method: A total of 379 participants were included (190 student nurses, 189 registered nurses). The Fat Phobia Scale and Belief About Obese Persons Scale were used to determine the prejudice. Findings: Registered nurses were found to have more negative prejudices toward obese persons than those of student nurses. These prejudices were determined to be influenced by the nurses' body mass index and having an obese person in the family. Practical Implications: Both groups had negative prejudices toward obese persons, there was a higher level of prejudice among the registered nurses. These prejudices can have a negative impact on healthcare practices.
