Obesity and certain associated environmental factors increase the risk of type 2 diabetes mellitus (T2DM). This research aims to evaluate the relationship between sociodemographic characteristics, lifestyle, and diet quality with diabetes risk in overweight and obese Turkish adults. A questionnaire form including sociodemographic characteristics, lifestyle, body weight and height was applied. Finnish Diabetes Risk Score (FINDRISC) tool was used to identify the risk of T2DM. Dietary assessments were made by 24 h dietary recall and diet quality was evaluated by Healthy Eating Index-2015 (HEI-2015). According to FINDRISC score, 38.1% of adults were at mild risk, 21.9% were at moderate risk, and 20.9% were at high risk. In regression model, factors such as low educational level, being married, being employed, smoking, and the presence of comorbidities were found to increase the risk of developing diabetes. Each unit decline in HEI-2015, the risk of diabetes increased by a factor of 0.983. Sociodemographic factors, lifestyle, and diet quality significantly contribute to the increased risk of diabetes in overweight and obese Turkish adults. This trial was registered at clinicaltrials.gov with number NCT06614075 and registration date of 26 September 2024, retrospectively registered.

Type 2 diabetes mellitus (T2DM) is a worldwide health problem, and medical nutrition therapy is essential for improving the quality of life of patients with type 2 diabetes. Salt restriction may lead to iodine deficiency in these patients. Moreover, type 2 diabetes can be an indirect reason for thyroid disorders. This study was conducted to determine the relationship between dietary iodine intake, urinary iodine excretion and thyroid functions in people with T2DM. Iodine nutritional status was determined by a one day 24-h dietary recall and food-frequency questionnaire. Iodine status was detemined by urinary iodine excretion with morning urine sample. Iodine intake according to one day 24-h dietary recall was lower in T2DM patients [94.8 (76.0-112.0) μg] than people in control group [137.1 (123.1-165.4) μg] (p < 0.05). Iodine intake determined by food-frequency questionnaire rich in iodine was lower in T2DM patients [93.1 (84.4-113.9) μg] than people in control group [140.2 (125.1-166.1) μg] (p < 0.05). Mild iodine deficiency was found in %38.8 of diabetic and %55.1 of healthy individuals (p < 0.05). No significant relationship was found between urinary iodine excretion and thyroid function tests in groups (p > 0.05). However, the relationship between dietary iodine excretion and urinary iodine intake in the diabetic group was lower than in the control group (p < 0.05). With this respect, the results showed that while planning medical nutrition therapy for diabetic individuals, the risk of iodine deficiency should be considered.

Dietary supplements are concentrated sources of nutrients used as an addition to a normal diet with a nutritional or physiological effect. In this cross-sectional study, it was aimed to determine the factors of dietary supplement use, the related knowledge, and their relationship with supplement use in a faculty of health sciences among university students. This cross-sectional study was carried out with 333 voluntary university students from Ankara Yıldırım Beyazıt University, the Faculty of Health Sciences. A questionnaire form consisting of 5 sections was applied to the students by face-to-face interview method. The most remarked purposes of supplement use were to improve health (44.2%) and boost immunity (22.1%). There was no difference between age, gender, department, coexistent disease, tobacco smoking and alcohol consumption in terms of dietary supplement use (p = 0.611, p = 0.720, p = 0.682, p = 0.062, p = 0.491, and p = 0.658, respectively). No significant difference was observed between physical activity status, the duration of physical activity, dieting status, the source of diet program, daily frequency of main meals and snacks, body mass index (BMI) groups, and the reason for meal skipping among students according to dietary supplement use (p = 0.180, p = 0.205, p = 0.686, p = 0.226, p = 0.533, p = 0.449, p = 0.976, and p = 0.758, respectively). There was not any significant difference between physical activity status, the duration of physical activity, dietary supplement use, dieting status, the frequency of main meals and snacks and BMI in terms of total knowledge score of dietary supplements (p = 0.245, p = 0.713, p = 0.278, p = 0.067, p = 0.466, p = 0.647, and p = 0.851, respectively). Scientific attention should be paid to the use of dietary supplements. Arbitrary approaches can lead to unwanted interactions. Therefore, in order for health and government policies to be established related to dietary supplements, it is essential to determine the factors related to their use.

Background/Objectives: Hashimoto’s thyroiditis (HT) is an autoimmune disease influenced by genetic factors and environmental triggers that affect immune system function. Data suggest that vitamin D may also play a role in the etiopathogenesis of HT. Methods: This retrospective study included patients admitted to the Endocrinology and Metabolic Diseases Outpatient Clinic. Data from individuals aged 18 years and older were analyzed, including serum levels of thyroid-stimulating hormone (TSH), free triiodothyronine (fT3), free thyroxine (fT4), anti-thyroid peroxidase (anti-TPO), anti-thyroglobulin (anti-TG), and vitamin D. HT was diagnosed based on the presence of anti-TPO and/or anti-TG antibodies, while individuals with negative results for both were classified as non-HT. Thyroid function was categorized as euthyroid if TSH levels were between 0.55 mU/L and 4.78 mU/L and fT4 levels were between 0.89 ng/dL and 1.76 ng/dL; hypothyroid status was defined as TSH > 4.78 mU/L. Vitamin D levels were classified as deficient (<50 nmol/L), insufficient (50–74.9 nmol/L), or sufficient (≥75 nmol/L). Results: Of the total participants, 25,018 did not have HT, while 27,800 were diagnosed with HT. Vitamin D level was significantly higher in the HT group than the non-HT group (41.43 nmol/L and 39.44 nmol/L, p < 0.001). Vitamin D deficiency was present in 65.5% of the non-HT group and 62.1% of the HT group (p < 0.001). Subgroup analyses based on thyroid function showed that vitamin D levels were highest in the euthyroid HT group and similar in the euthyroid non-HT, hypothyroid non-HT, and hypothyroid HT groups (p < 0.001). Conclusions: In conclusion, while vitamin D levels were higher in the HT group compared to the non-HT group, no clinically significant association between vitamin D levels and HT or autoantibody positivity was observed. Vitamin D deficiency was more prevalent in the hypothyroid group compared to the euthyroid group. This study suggests that although vitamin D deficiency may not be directly involved in the pathogenesis of HT, it may still play a role in modulating immune activity or influencing the disease phenotype..

Objective: This study was conducted to examine the relationship between eating disorder risk, social media, and psychological factors among high school students. Material and Methods: In this cross-sectional study, eating disorder risk was assessed using the Eating Attitudes Test-40 (EAT-40), fear of being disliked on social media was evaluated using the Social Media Fear of Dislike Scale (SMFDS), psychological factors were measured with the Depression, Anxiety and Stress Scale-42 (DASS-42) high school form. Results: According to the EAT-40 scale, 15.4% of students were at risk for eating disorders. Based on the DASS-42 scale, extremely severe levels of depression, anxiety, and stress were revealed in 18.3%, 21.5%, and 10.5% of students, respectively. Female students had higher levels of fear of being disliked on social media, depression, anxiety, and stress compared to male students; however, no significant difference was observed regarding eating disorder risk. A positive and significant correlation was found between eating disorder risk and fear of being disliked on social media, depression, anxiety, and stress values (r=0.215, p<0.001; r=0.217, p<0.001; r=0.302, p<0.001; r=0.245, p<0.001, respectively). Conclusion: The risk of eating disorders in high school students is associated with social media use and psychological factors. These findings emphasize the need for a more detailed examination of the effects of social media use and related psychological factors on eating behaviors.

Aim: The use of herbal supplements is increasing today, and these products have a significant impact on individuals' health. The aim of this study is to examine the use and reasons for using herbal supplements, as well as to determine individuals' attitudes towards these products. Materials and Methods: The study was conducted with individuals aged 19-65 who use medications. A questionnaire containing questions about the participants' demographic characteristics, herbal supplement usage, and attitudes was administered by the researcher through face-to-face interviews. Results: Of the 274 participants in the study, 10.6% use herbal supplements, with the most preferred products being ginseng, St. John's wort, and garlic (20.7%, 27.6%, and 37.9%, respectively). It was found that individuals who consume alcohol use herbal supplements 3.188 times more, and those who exercise use them 3.470 times more than those who do not (p=0.043, p=0.015, respectively). Most herbal supplement users agreed with the statement, "Herbal supplements can be used immediately when experiencing symptoms related to illness," while most non-users disagreed (p
