    Orthorexia 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.

    The Effectiveness of Juniper and Thyme Essential Oils in Reducing the Physiological Symptoms of Test Anxiety in Medical Students
    (Mersin University, 2026) Özcan, Gülbahar Böyük; Bayraktar, Bülent; Bozok, Ümmü Gülşen; Erkiliç, Tuğçe Orkun
    Objective: Medical students struggle with exam anxiety, which negatively affects cognitive and academic performance. Aromatherapy has become popular as an alternative to pharmacological treatments. This study examines how juniper and thyme essential oils psychophysiologically affect undergraduate students' exam anxiety. Juniper and thyme aroma inhalation was tested on asprosin, cyclic guanosine monophosphate response element binding protein (CREB), cortisol, and exam anxiety in students taking exams. Method: A random sample of 80 healthy students aged 18-25 from the Faculty of Medicine was collected during final exams. Participants were their own controls, and saliva was collected before and after aromatherapy. Saliva samples were tested for asprosin, CREB, and cortisol using ELISA. Heart rate, oxygen saturation, systolic pressure, diastolic pressure, and body temperature were monitored before and after aroma inhalation. Findings: According to the findings of this study, juniper and thyme aromatherapy were effective in increasing the average saliva levels of Asprosin, CREB, and cortisol hormones, with the most significant decrease observed in the groups receiving juniper aromatherapy (p

    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, Bülent
    Glossophobia (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.
