    The relationship between body mass index and stage/grade of periodontitis: a retrospective study
    (2021) Cetin, Mehtap Bilgin; Sezgin, Yasemin; Onder, Canan; Bakirarar, Batuhan; 34709456
    Objectives Possible impact of obesity on stage and grade of periodontitis has never been investigated before. This study aimed to examine the association between body mass index (BMI) and stage/grade of periodontitis per the current classification of periodontal diseases. Material and methods A total of 142 patients (82 males/60 females) were included in this study. "2017 World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions" was taken as basis to characterize the stage/grade of periodontitis. Age, gender, smoking status, and frequency of tooth brushing, and medical data of the patients including hypertension, hyperlipidemia, BMI, and diabetes mellitus were obtained from the patient's hospital records. Obesity was assessed by BMI using the "World Health Organization" criteria. For estimating the association between BMI and periodontitis, logistic regression analysis was utilized. Results BMI was statistically associated with clinical attachment loss (CAL), probing pocket depth (PPD), Plaque index (PI), stage and grade of periodontitis, and number of remaining teeth (p < 0.001, p < 0.05, p < 0.05, p < 0.05, p < 0.001, respectively). According to the multiple regression analysis results, those with BMI 25-29.9 were found to be at risk of being stage III-IV 3.977 times (95% CI: 1.831-8.640, p < 0.001) higher than those with BMI < 25, and similarly, those with BMI >= 30 were found to be at risk of being stage III-IV 4.062 times (95% CI: 1.315-12.549, p = 0.015) higher than those with BMI < 25. No relationship was found between obesity and grade of periodontitis according to multivariate analysis. Conclusions BMI increases the likelihood of stage III and stage IV periodontitis; however, it does not have an impact on the grade of periodontitis.

    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-2935-2021
    Background 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.

    Effect of Body Mass Index on Middle Ear Resonance Frequency
    (2018) Sozen, Miray; Oz, Isilay; Erbek, Selim; 29460823
    OBJECTIVE: Multifrequency tympanometry (MET) analyzes tympanograms obtained using different probe tones between 226 and 2000 Hz. An important parameter of MET is resonance frequency (RF). Studies have recently demonstrated that the RF value can vary depending on many factors. To provide new data regarding MET, middle ear RF values were investigated with regard to body mass index (BMI). MATERIALS and METHODS:This study included 78 volunteers (i.e., 156 ears) aged 18-40 years who did not have healing loss and whose otoscopic examinations were normal. Hearing thresholds were measured using pule tone audiometry, and RF values were recorded with immitansmetric measurements. The participants were divided into the following three groups according to their BMI: <18.5 kg/m2, Group 1; 18.5-24.9 kg/m(2), Group 2; and >25 kg/m(2), Group 3. The RE values were also analyzed. RESULTS: Although there was no significant difference between Groups 1 and 2 in terms of RF values, a significant difference was observed between Groups 1 and 3 and between Groups 2 and 3. CONCLUSION: In the light of these data, BMI values should be considered when middle ear RF values are assessed.
