Item Is obesity a problem that threatens oral health in adults?(2021) Yilmaz, Busra; Somay, Efsun; 0000-0003-0633-5648Purpose: Obesity is one of the increasingly negative factors affecting oral and dental health directly or indirectly in many developed and developing countries. The aim of this study was to determine the relationship between obesity and dental problems in adults and to investigate the effect of obesity on oral and dental health. Materials and Methods: 200 patients over the age of 18 who applied with various dental complaints were examined clinically and radiologically. They were classified as 50 healthy females, 50 healthy males, 50 obese females, and 50 obese males according to the body mass index determined by the World Health Organization (healthy individual < 30.0 kg / m(2) and 30.0 kg / m(2) <= obesity individual). Sociodemographic characteristics, dental health status, and data of all patients were examined. Results: A statistically significant relationship was found between obesity and the number of tooth loss, the number of dental caries, educational status, and the frequency of applying to the dentist. Periodontitis was detected at a higher rate in the obesity group (58 %) compared to the control group, but the relationship between obesity and periodontal status was not statistically significant. Conclusion: Dental problems such as tooth loss, the number of dental caries, and periodontitis were higher in the obesity group, and this result showed that obesity threatens oral and dental health. To prevent these problems, there is a need for preventive strategies and increasing awareness of oral and dental health in obese patients.Item The Relationship between Daily Fructose Consumption and Oxidized Low-Density Lipoprotein and Low-Density Lipoprotein Particle Size in Children with Obesity(2021) Gungor, Ali; Balamtekin, Necati; Özkececi, Coskun Firat; Aydin, Halil İbrahim; 0000-0001-7994-4394; 34557400; AHD-1839-2022Purpose: Obesity has become a very significant health problem in childhood. Fructose taken in an uncontrolled manner and consumed in excessive amounts is rapidly metabolized in the body and gets converted into fatty acids. This single center prospective case-control study aims to investigate the relationship between fructose consumption and obesity and the role of fructose consumption in development of atherosclerotic diseases. Methods: A total of 40 obese and 40 healthy children who were of similar ages (between 8 and 18 years) and sexes were included in the study. In the patient and control groups, the urine fructose levels, as well as the levels of oxidized low-density lipoprotein (LDL), small dense LDL, Apolipoprotein A and Apolipoprotein B values, which have been shown to play a role in development of atherosclerotic diseases, were measured. Results: The levels of oxidized LDL and small dense LDL and the ratio of Apolipoprotein A/Apolipoprotein B were found to be significantly higher in the patient group. Conclusion: We found that urinary fructose levels were higher in the obese children than the healthy children. Our results suggest that overconsumption of fructose in children triggers atherogenic diseases by increasing the levels of small dense LDL and oxidized LDL and the ratio of Apolipoprotein B/Apolipoprotein A.Item The relationship between body mass index and renal length in obese children(2020) Parmaksiz, Gonul; Kekec, Senay Demir; Cengiz, Nurcan Dinler; Noyan, Aytul; 0000-0003-2373-1837; 31997076; AAD-5713-2021; AAM-2935-2021Background Obesity in the pediatric population is a severe public health problem and is associated with various comorbidities. Renal length is an important clinical parameter for the diagnosis and follow-up of renal diseases. The aim of this study was to determine the relationship between renal length (measured ultrasonographically) and body mass index (BMI) in obese children, and to develop nomograms for renal length according to BMI. Methods Renal ultrasound was performed in 368 children without renal disease. Each child's age, gender, weight, height, and BMI (kg/m(2)) were recorded. The children were divided into three groups according to BMI percentiles: obese group: BMI >= 95th percentile; overweight group: BMI 85th-94th percentile; normal weight group: BMI 5th-84th percentile. Results Weight, height, BMI, and right and left renal length differed significantly between the three groups (p = 0.001). There were significant correlations between renal length with age, weight, height, and BMI. Measurement of renal length was independently associated with BMI, age, and height. BMI was used to create renal length nomograms for obese children, based on multiple regression analysis (R-2 = 0.32 and p = 0.0001). Mean renal length was highest in the obese group (96.9 +/- 13.4 mm) and lowest in the normal weight group (88.3 +/- 12.9 mm). Conclusions Ultrasonographic measurement of the renal length according to BMI in children can be a useful method in evaluating these children. Smaller-than-normal kidneys can easily remain undiagnosed in obese and overweight children and this nomogram offers an additional method to evaluate the renal size in obese children.Item Impact of Obesity on the Metabolic Control of Type 2 Diabetes: Results of the Turkish Nationwide Survey of Glycemic and Other Metabolic Parameters of Patients with Diabetes Mellitus (TEMD Obesity Study)(2019) Bascil Tutuncu, Neslihan; Bozkus, Yusuf; Bozkirli, Emre; 30893706Background: Obesity is the main obstacle for metabolic control in patients with type 2 diabetes. Turkey has the highest prevalence of obesity and type 2 diabetes in Europe. The effect of obesity on the metabolic control, and the macro-and microvascular complications of patients are not apparent. Objectives: This nationwide survey aimed to investigate the prevalence of overweight and obesity among patients with type 2 diabetes and to search for the impact of obesity on the metabolic control of these patients. We also investigated the independent associates of obesity in patients with type 2 diabetes. Methods: We consecutively enrolled patients who were under follow-up for at least 1 year in 69 tertiary healthcare units in 37 cities. The demographic, anthropometric, and clinical data including medications were recorded. Patients were excluded if they were pregnant, younger than 18 years, had decompensated liver disease, psychiatric disorders interfering with cognition or compliance, had bariatric surgery, or were undergoing renal replacement therapy. Results: Only 10% of patients with type 2 diabetes (n = 4,648) had normal body mass indexes (BMI), while the others were affected by overweight (31%) or obesity (59%). Women had a significantly higher prevalence of obesity (53.4 vs. 40%) and severe obesity (16.6 vs. 3.3%). Significant associations were present between high BMI levels and lower education levels, intake of insulin, antihypertensives and statins, poor metabolic control, or the presence of microvascular complications. Age, gender, level of education, smoking, and physical inactivity were the independent associates of obesity in patients with type 2 diabetes. Conclusion: The TEMD Obesity Study shows that obesity is a major determinant of the poor metabolic control in patients with type 2 diabetes. These results underline the importance of prevention and management of obesity to improve health care in patients with type 2 diabetes. Also, the results point out the independent sociodemographic and clinical associates of obesity, which should be the prior targets to overcome, in the national fight with obesity. (c) 2019 The Author(s) Published by S. Karger AG, BaselItem beta-3AR W64R Polymorphism and 30-Minute Post-Challenge Plasma Glucose Levels in Obese Children(2015) Verdi, Hasibe; Kinik, Sibel Tulgar; Yalcin, Yaprak Yilmaz; Sahin, Nursel Muratoglu; Yazici, Ayse Canan; Atac, F.Belgin; 25800470Objective: In this study, we aimed to investigate the association of W64R polymorphism of the beta 3-adrenergic receptor gene (beta-3AR) with childhood obesity and related pathologies. Methods: beta-3AR gene W64R genotyping was carried out in 251 children aged 6-18 years. Of these subjects, 130 were obese (62 boys) and 121 were normal-weight (53 boys). In the obese group, fasting lipids, glucose and insulin levels were measured. Oral glucose tolerance test (OGTT) was performed in 75 of the obese patients. Results: The frequency of W64R genotype was similar in obese and nonobese children. In obese children, relative body mass index, waist-to-hip ratio, serum lipid, glucose and insulin levels, as well as homeostasis model assessment of insulin resistance (HOMA-IR) scores were not different between Arg allele carriers (W64R and R64R) and noncarriers (W64W). In 75 obese children, OGTT results showed that Arg allele carriers had significantly higher 30-minute glucose levels (p=0.027). Conclusion: W64R polymorphism of the beta-3AR gene is not associated with obesity and waist-to-hip ratio in Turkish children. Although there were no relationships between the genotypes and lipid, glucose/insulin levels or HOMA-IR, the presence of W64R variant seemed to have an unfavorable influence on early glucose excursion after glucose loading.Item Low serum 25(OH)D levels are associated to higher BMI and metabolic syndrome parameters in adult subjects in Turkey(2015) Tosunbayraktar, Guler; Bas, Murat; Kut, Altug; Buyukkaragoz, Aylin Hasbay; 26958017Background: The aim of this study was to investigate the association of 25(OH) D levels with biochemical, anthropometric, and metabolic data obtained from normal and obese people. Methods: This study was carried out on 90 individuals between the ages of 18 to 63 that had various body mass indexes. Blood samples and anthropometric measurements were taken. Results: Waist circumferences, fat mass, LDL cholesterol levels, HDL cholesterol levels, 25(OH) D levels, and triglyceride levels were significantly different according to the body mass index groups of the participants (p<0.05). When compared to the normal body mass index group, both other groups (overweight and obese) had higher waist circumferences, triglyceride levels, LDL cholesterol levels, fasting insulin levels, HOMA-IR ratios, parathyroid hormone levels, and fat mass, and had lower 25(OH) D levels (p<0.05). The overweight group participants had higher 25(OH) D levels than the obese group, and had lower waist circumferences, fat mass, fasting insulin level, HOMA-IR ratios, and HbA1C and PTH levels than those in the obese group (p<0.05). Conclusion: In conclusion, the mean level of 25(OH) D is very low in overweight and obese individuals and low serum 25(OH) D levels appear to be associated with obesity, visceral obesity, hypertriglyceridemia, insulin resistance, and metabolic syndrome in obese patients.Item Body Mass Index below Obesity Threshold Implies Similar Cardiovascular Risk among Various Polycystic Ovary Syndrome Phenotypes(2016) Bagir, Gulay Simsek; Bakiner, Okan S.; Bozkirli, Emre; Cavlak, Gulhan; Serinoz, Hulya; Ertorer, M. Eda; 26335185Objective: The aim of this study was to determine the cardiometabolic risk factors in different polycystic ovary syndrome (PCOS) phenotypes. Subjects and Methods: This cross-sectional study was performed between 2010 and 2011. Eighty-nine patients with PCOS and 25 age- and weight-matched healthy controls were included in the study. Patients were grouped using the Rotterdam 2003 criteria as: group 1, oligomenorrhea and/or anovulation (ANOV) and hyperandrogenemia (HA) and/or hyperandrogenism (n = 23); group 2, ANOV and polycystic ovaries (PCO; n = 22); group 3, HA and PCO (n = 22); group 4, ANOV, HA and PCO (n = 22); group 5, controls (n = 25). Laboratory blood tests for diagnosis and cardiometabolic risk assessments were performed. Insulin resistance (IR) was calculated in all patients with the homeostasis model assessment of IR (HOMA-IR) formula. An euglycemic hyperinsulinemic clamp test was performed on 5 randomly selected cases in each subgroup, making 25 cases in total, and indicated as the 'M' value (mg/kg/min), which is the total body glucose disposal rate. Results: The mean BMl values of the groups were: group 1, 26.1 +/- 5.3; group 2, 27.9 +/- 5.2; group 3, 24.3 +/- 4.2; group 4, 27.9 +/- 7.5; group 5, 24.7 +/- 5.2 (p > 0.05). There were no differences in the lipid profile, plasma glucose, HOMA-IR, insulin and M values between the groups (p > 0.05). Phenotypes with oligomenorrhea/anovulation (groups 1, 2 and 4) were more obese than group 3 (p = 0.039). Conclusions: The cardiometabolic risk profile was similar among the PCOS subgroups. This finding could be attributed to the mean BMl values, which, being below 30, were not within the obesity range. Obesity appeared to be an important determinant of high cardiovascular risk in PCOS. (C) 2015 S. Karger AG, BaselItem EVALUATION AND MANAGEMENT OF DIFFICULT AIRWAY IN OBESITY: A SINGLE CENTER RETROSPECTIVE STUDY(2016) Ayhan, Asude; Kaplan, Serife; Kayhan, Zeynep; Arslan, Gulnaz; 27276769The primary aim of this single center retrospective study was to evaluate difficult mask ventilation (DMV) and difficult laryngoscopy (DL) in a unique group of obese patients. A total of 427 adult patients with body mass index (BMI) >= 25 and surgically treated for endometrial cancer from 2011 to 2014 were assessed. Additional increase in BMI, comorbidities, bedside screening tests for risk factors, and the tools used to manage the patients were noted and their effects on DMV and/or DL investigated. Every escalation in the number of risk factors increased the probability of DMV 2.2-fold, DL 1.8-fold and DMV+DL 3.0-fold. Among bedside tests, limited neck movement (LNM), short neck (SN) and absence of teeth were significant for DMV (p<0.05), LNM, SN and obstructive sleep apnea for DL (p<0.05), and LNM and SN for DMV+DL (p<0.05). However, a 10-point increase of BMI was not an independent risk factor when patients with BMI >25% were considered. In conclusion, LNM and SN are independent risk factors for developing DMV and/or DL in obese endometrial cancer patients, while BMI increase over 30 was not additionally affecting difficult airway.Item Prevalence of Proteinuria in School-Aged Turkish Children, and Its Association with Obesity and Hypertension(2017) Kazanci, Nafia Ozlem; Gul, Ali; Ozer, Samet; Yilmaz, Resul; Sonmezgoz, Ergun; Kasap, Tuba; Takci, Sahin; Unuvar, Seyma; Onder, Yalcin; Citil, RizaAim: In kidney diseases, renal damage may be mild and initially asymptomatic. Proteinuria, a marker of kidney injury, directly contributes to chronic tubulointerstitial damage. We investigated the prevalence of proteinuria (POP) in school-aged children in Turkey. Materials and Methods: The cluster sampling method was used to calculate the required size of the study group for this cross-sectional study. Urine samples were randomly obtained to determine urinary protein/creatinine ratio (Upr/Ucr) from 1374 children aged 6 to 18 years. POP was also specifically assessed in hypertensive and obese children. Results: The mean age of the subjects was 11.68 +/- 3.43 years. The children were from rural (23.9%) and urban (76.1%) regions of Tokat, Turkey. Upr/Ucr >= 0.20 was detected in 92 children, corresponding to a POP rate of 6.7%, without any statistically significant difference between girls and boys. Among 141 obese children, 16 (11.3%) and 76 of 1233 non-obese children (6.2%) had proteinuria (p<0.05). Children with hypertension had a POP of 7.5% compared to the 6.7% of those without hypertension (p>0.05). Conclusion: Among school-aged Turkish children POP was 6.7%. POP was higher in obese than in non-obese children. But there was no association between POP and hypertension. While screening programs allow the early detection of renal disease, further cohort studies are required to be able to suggest urinary screening programs.Item Factors associated with social anxiety disorder in a group of obese Turkish female patients(2018) Ozsahin, Akath Kursad; Altintas, Ebru; 0000-0001-8844-3946; 0000-0003-2735-4805; 29714460; AAN-3522-2021; G-8832-2015Background/aim: Mental disorders may accompany obesity. This study aims to evaluate the association between social anxiety disorder (SAD) and obesity and the risk factors for SAD in obese female patients. Materials and methods: A total of 114 obese patients and 110 healthy controls were included. The Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), State and Trait Anxiety Inventory (STAI I-II), and Liebowitz Social Anxiety Scale (LSAS) were administered to assess anxiety, depression, and social anxiety levels. Scale scores were analyzed statistically. Results: The rate of SAD in obese female patients was found to be 8.8%. Anxiety, depression, and social anxiety levels were significantly higher in the obesity group compared to the control group (P < 0.05). According to linear regression analyses, a significant association between LSAS anxiety level and age, prior surgery, social support, history of being teased, BDI, and BAI was found. Conclusion: The present study shows that many factors are related to obesity and SAD in obese female patients. The clinical implications of these findings should be considered. Interventions for these factors may help prevent SAD in obese female patients.
