Publication Open Access Status of weight change, lifestyle behaviors, depression, anxiety, and diabetes mellitus in a cohort with obesity during the covid-19 lockdown: Turk-com study group(2022-08-01) YAVUZ, DİLEK; KÜÇÜK YETGİN, MERAL; Yazıcı D., Fersahoğlu M. M., Fersahoğlu T., Bulut N. E., Çiğiltepe H., Çeler Ö., Sancak S., Sulu C., Durcan E., Şahin S., et al.Introduction: The coronavirus disease 2019 (COVID-19) pandemic led to a lockdown period. Confinement periods have been related to unhealthy lifestyle behaviors. Our study aimed to determine weight change, changes in eating and exercise habits, the presence of depression and anxiety, and diabetes mellitus (DM) status in a cohort of patients with obesity. Methods: The study was undertaken in nine centers of Collaborative Obesity Management (COM) of the European Association for the Study of Obesity (EASO) in Turkey. An e-survey about weight change, eating habits, physical activity status, DM status, depression, and anxiety was completed by patients. The International Physical Activity Questionnaire (IPAQ) score was used to determine physical activity in terms of metabolic equivalents (METs). A healthy nutrition coefficient was calculated from the different categories of food consumption. The Patient Health Questionnaire (PHQ-9) and General Anxiety Disorder (GAD-7) Questionnaire were used for determining depression and anxiety, respectively. Results: Four hundred twenty-two patients (age 45 +/- 12.7 years, W/M = 350/72) were included. The healthy nutrition coefficient before the pandemic was 38.9 +/- 6.2 and decreased to 38.1 +/- 6.4 during the pandemic (p < 0.001). Two hundred twenty-nine (54.8%) patients gained weight, 54 (12.9%) were weight neutral, and 135 (32.3%) lost weight. Patients in the weight loss group had higher MET scores and higher healthy nutrition coefficients compared with the weight gain and weight-neutral groups (p < 0.001). The PHQ and GAD scores were not different between the groups. Percent weight loss was related to healthy nutrition coefficient (CI: 0.884 [0.821-0.951], p = 0.001) and MET categories (CI: 0.408 [0.222-0.748], p = 0.004). One hundred seventy patients had DM. Considering glycemic control, only 12 (8.4%) had fasting blood glucose <100 mg/dL and 36 (25.2%) had postprandial BG <160 mg/dL. When patients with and without DM were compared in terms of dietary compliance, MET category, weight loss status, PHQ-9 scores, and GAD-7 scores, only MET categories were different; 29 (11.7%) of patients in the nondiabetic group were in the highly active group compared with 5 (2.9%) in the diabetic group. Conclusion: The COVID-19 lockdown resulted in weight gain in about half of our patients, which was related to changes in physical activity and eating habits. Patients with DM who had moderate glycemic control were similar to the general population in terms of weight loss but were less active.Publication Open Access Comparison of kinanthropometric profiles of elite turkish taekwondo players with or without medals in european championships(2022-02-01) AGOPYAN, ANİ; KÜÇÜK YETGİN, MERAL; RAMAZANOĞLU, NUSRET; CUMBUR, CANSEL; Agopyan A., Yesilcimen T., Gocmez H. B., Ozturk B., Gulesce S., Bulut T., Gungor K. C., Ucar D. H., Ulucan Y., Cumbur C., et al.This study aims to determine the possible differences anthropometric characteristics and body composition profiles of elite taekwondo players with or without medals in European championships. Twenty-one black-belt elite taekwondo athletes (17.4 +/- 1.2 years) from the Turkish national team were divided into two groups, namely, medalists (MEC; n =11) and non-medalists (NmEC; n=10) in European championships. Twenty-eight anthropometric measurements including height, body mass, length, circumferences, breadth, and skinfolds were taken following the standard techniques proposed by the International Society for the Advancement of Kinanthropometry (ISAK). Body composition variables were evaluated by using skinfold thickness measurements. Results demonstrated that anthropometric and body composition, variables did not differ significantly between medalist and non-medalist taekwondo players (p>0.01). Our athletes have a low percentage of body fat and high muscle mass profile. Medalist and non-medalist elite Turkish taekwondo players in the European championships do not differ in terms of anthropometric and body composition components. They have a similar body composition profile suitable for taekwondo players and within acceptable healthy ranges. The present study assists coaches in the formulation of appropriate training programs aiming the development for managing the body composition status of players, which will be associated with high-level performance in taekwondo. Future studies should include body composition and somatotype profile inspection throughout the weight categories.Publication Metadata only The effect of a nutrition program for weight loss during the pre-competition period on the body composition, hydration, and mood profile of elite Greco–Roman wrestlers(2023-01-01) KÜÇÜK YETGİN, MERAL; AGOPYAN, ANİ; Ayar M., KÜÇÜK YETGİN M., AGOPYAN A., Elmacioglu F.Objective: The study aimed to investigate the effect of a nutrition program introduced among elite Greco–Roman wrestlers during the weight-loss period before the competition on the athletes’ body composition, hydration, and mood. Methods: The experimental group comprised the Greco–Roman Wrestling National Team (U23) of different weights (n = 8) and the control group consisted of substitute athletes (n = 8) with the same weights as the experimental group. To achieve the target weight, the experimental group followed a personalized weight loss program under the supervision of a dietitian, whereas the control group lost weight using their own methods. The athletes completed a mood profile questionnaire, food and fluid consumption, urine density evaluation, anthropometric measurements, and body composition assessments were performed. Results: The athletes who followed a balanced diet under the guidance of a dietician had decreased body mass index, body weight, body fat rates (%), and urine density compared to the athletes who used traditional methods (P < 0.05). Negative changes in the control group and positive changes in the experimental group were observed in the mood profile scores (P < 0.05). There was a higher decrease in variables, including energy (kcal), carbohydrate (g/kg), protein (g/kg), fat (g/kg), and micronutrient consumption, in the control group (P < 0.05). Conclusion: Change in nutritional intake at the macro and the micro level was found to be more balanced among male athletes who followed a regular and planned nutrition program under a dietitian’s supervision. In addition, the experimental group had decreased body fat percentages and urine density and underwent a positive change as confirmed by their mood profile.
