Öğe Determination of Salivary Cortisol Levels and Nutrition, Smoking and Physical Activity Status of University Students during the Exam Period(2024) Erkılıç, Tugçe Orkun; Bayraktar, Bülent; Erkılıç, Ali Ozan; Ozcan, Gulbahar BoyukObjective: The aim of this study is to determine the salivary cortisol levels and nutrition, smoking and physical activity status of university students during the exam period. Method: This study was conducted at Bayburt University Faculty of Health Sciences during the 2023-2024 final exam period. A questionnaire determined the demographic characteristics, dietary and physical activity behaviors, while anthropometric measurements were taken and nutritional status was evaluated. ELISA analyzed the cortisol hormone levels in saliva samples taken before and after the final exam. Results: The study was conducted on 120 volunteer students between the ages of 18-25 who had no clinical health problems. In the study, a significant difference was found between the students' salivary cortisol levels before and after the exam (p<0.05). Cortisol levels were found to be lower in male students (n=60) than in female students (n=60) (p<0.05). Cortisol levels were found to be higher in smokers than in non-smokers (p<0.05) Exam anxiety was found to be higher in female students (p<0.05). No significant change was observed in terms of physical activity, nutritional behaviors or food preferences during the exam period (p>0.05). Conclusion: One of the important stress factors for students is the exam period. It is important to examine the effects on nutrition, physical activity and smoking during this period. Cortisol levels are an important marker for such studies and are thought to contribute to the evaluation of the effectiveness of stress prevention strategies.Öğe Investigation of the relationship between orthorexic tendencies and some anthropometric measurements and variables in university students(2024) Erkılıç, Tugçe Orkun; Bayraktar, Bülent; Erkılıç, Ali Ozan; Ozcan, Gulbahar Boyuk; Bozok, Ümmü Gülşen; Bülbül, Ali Savaş; Turan, MerveOrthorexia nervosa (ON) is a type of eating disorder marked by an excessive preoccupation with eating healthily to preserve and promote health, which surpasses normal levels of concern. This study aims to investigate the correlation between orthorexic tendencies, anthropometric measurements, and several other characteristics among university students. A cross-sectional study was done with a sample size of 307 university students from various departments, consisting of 228 females and 79 males. The data-gathering process consisted of administering a demographic information form and the ORTO-11 questionnaire. Anthropometric measurements, such as weight, height, waist circumference, hip circumference, and chest circumference, were measured. In addition, Body Mass Index (BMI) was calculated. The TANITA BC-418 equipment was used to measure the weight of the participants, while a flexible tape measure was used to measure their height, waist circumference, hip circumference, and chest circumference. The BMI was calculated by the individual's weight (in kilograms) by the square of their height (in meters). The data analysis encompassed the utilization of descriptive statistics, t-tests, variance analysis, and Pearson correlation analysis. A score of 25 or lower on the ORTO-11 scale was categorized as orthorexic, whereas a score higher than 25 was deemed normal. The average age and orthorexia scores of the subjects were 20.81±1.86 and 27.76±4.42 for females, and 21.38±4.14 and 28.11±4.37 for males, respectively. It was determined that 29.3% of the participants were found to display orthorexic tendencies, while the remaining 70.7% did not. There were no statistically significant variations in age, hip circumference, and orthorexia scores across genders (p>0.05). No statistically significant relationship was found between the total orthorexia scores and BMIs of the individuals (r=-.051, p>0.05). ON is associated with psychological and social complications, which in turn contribute to the development of disordered eating patterns. The results of this study indicate that determining the frequency of orthorexic tendencies among university students may contribute to the development of strategies for its prevention.Öğe Relationship of progranulin response with some physio-biochemical parameters in Akkaraman sheep(Univ Agriculture, Fac Veterinary Science, 2023) Bayraktar, Buelent; Tekce, Emre; Genc, Murat; Kaya, Hacer; Ozcan, Gulbahar Boyuk; Aydemir, Seyma; Kotan, Goksad CemilProgranulin (PGRN) is a multifunctional protein that is critical in the retention of embryos in the endometrium of the uterus and the protection of cervical tissue during fetal growth. In case of PGRN release and dysfunction, cervical tissue may remodel (regeneration) and lead to the risk of abortion. Serum PGRN level in sheep and its variation according to different physiological periods and its relationship with some biochemical parameters are unknown. In this study, the relationship between early lactation, early and late pregnancy serum PGRN levels and some biochemical parameters in Akkaraman sheep was investigated for the first time. In the literature search, no similar studies were found on the relationship between early lactation, early and late pregnancy serum PGRN levels and some biochemical parameters in Akkaraman sheep. The research was carried out on 90 Akkaraman sheep reared in the same herd under the same care and feeding conditions. In the study, Akkaraman ewe were divided into 3 groups as early lactation, early pregnancy and late pregnancy. 1st group is early lactation period ewe (first 60 days of lactation), (n = 30), 2nd group is in the first period of pregnancy (on the 0-90th day of the first pregnancy (n = 30)), 3rd group is in the late pregnancy of pregnancy (100-150 days of pregnancy (n = 30)) was created. Blood samples from vena jugularis were taken before morning feeding from the animals that formed the study groups. PGRN levels in serum were determined by ELISA method. In addition, glucose, calcium (Ca), magnesium (Mg), phosphorus (P), total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL), high density lipoprotein (HDL), very low density lipoprotein (VLDL) levels were analyzed in biochemistry autoanalyzer. As a result of the study, lactation and early pregnancy and late pregnancy mean serum PGRN levels were determined as 1.93, 1.78, 1.33 ng mL-1, respectively. The serum PGRN, glucose, Ca, Mg, P, TC, TG, LDL, HDL and VLDL levels of sheep with late pregnancy, early lactation and early pregnancy periods, which constitute the study groups, were found to be statistically significant (P<0.05). Our results have shown that due to the physiological role of PRGN in keeping the embryo in the endometrium of the uterine and in preserving the cervical tissue during fetal growth, there may be a useful parameter in the pursuit of the pregnancy process.Öğe The impact of aromatherapy on glossophobia among medical students: A study on cortisol levels and stress reduction(2024) Ozcan, Gulbahar Boyuk; Bozok, Ümmü Gülşen; Battal, Fetullah; Bayraktar, BülentGlossophobia (fear of public speaking, presentation anxiety) is an anxiety disorder characterized by extreme fear and anxiety about public speaking. Glossophobia is a very common phobia worldwide, reportedly affecting 75% of the population. This study aims to examine the effects of different aroma inhalations (Thyme and Juniper) on public speaking anxiety, and salivary cortisol hormone levels in university students. The sample of the research consisted of a total of 104 university students, male and female, between the ages of 18-20. In the first step, cortisol hormone levels were determined using the ELISA technique in the saliva samples taken from the university students included in the study. The average salivary cortisol hormone level and public speaking anxiety levels of the university students participating in the study showed a positive and statistically significant relationship (p=0.001). There is a significant negative correlation between the participants' public speaking anxiety and post-thyme oil status at a 99% confidence level and a 1% significance level, r=-.318. When public speaking anxiety and juniper oil were analyzed, a significant negative relationship was found at r=-.290, a 99% confidence level, and a 1% significance level. It was also concluded that inhalation of 2% thyme essential oil in individuals with high glossophobia is both safe and beneficial in reducing anxiety levels.
