    (Carbone Editore, 2015) Türker, Yasemin; Baltacı, Davut; Türker, Yasin; Öztürk, Serkan; Iliev, Darko; Sarıgüzel, Yunus Cem; Alaşan,Fatih
    Aims: Aimed to determine the frequency, demographic, clinical and inflammatory parameters of metabolically healthy obese (MHO), metabolically unhealthy obese (MuHO) and metabolically healthy lean body individuals (MHLB). Materials and methods: The cross-sectional study was carried out between February 2013 and January 2014. The consecutive patients who admitted to outpatient clinic of obesity and check-up of family medicine, Duzce University, school of medicine, were enrolled. The socio-demographic features and medical history, anthropometric measurements, blood pressure records, blood samples and body fat analysis of total of 1958 patients were obtained. The patients were assigned into three groups as: MHO. MuHO and MHLB. Results: A total of 1958 patients were included. Mean homeostatic model assessment of insulin resistance (HOMAIR) value was significantly higher in subjects with MuHO than with MHO and MHLB (p<0.001 and p<0.001, respectively). Mean high density lipoprotein cholesterol (HDL-chol) was significantly lower in subjects with MuHO than in both MHO and MHLB (p<0.001). Mean low density lipoprotein cholesterol (LDL-chol) and total cholesterol was significantly higher in MuHO subjects than in MHO and MHLB (p=0.001 and p<0.001; p=0.002 and p<0.001), and lower in MHLB subjects than MHO and MuHO subjects (p<0.001 and p<0.001). Mean high-sensitivity C-reactive protein level was significantly different between groups (p<0.001), and lowest mean level was observed in subjects with MHLB (1.49 +/- 2.27 mg/dL) and highest mean level was observed in subjects with MuHO (5.32 +/- 5.71 mg/dL). Similarly, mean uric acid level was significantly higher in subjects with MuHO than in those with MHO and MHLB (p<0.001 and p<0.001. respectively). Mean uric acid level in MHLB group was lower than MHO and MuHO (p<0.001 and p<0.001, respectively). Conclusion: Obese individuals with metabolically healthy carried high risk for cardiovascular diseases and subclinical inflammation as well as metabolically unhealthy obese individuals, but carried greater risk than individuals with metabolically healthy lean body.

    Evaluation of serum Vitamin B12 level and related nutritional status among apparently healthy obese female individuals
    (Medknow Publications & Media Pvt Ltd, 2017) Baltacı, Davut; Deler, Mehmet Harun; Türker, Yasin; Ermiş, Fatih; Iliev, Darko; Velioğlu, Usame
    Objective: Obesity is a major public health problem and great risk for not only cardiovascular diseases but also cancer, musculoskeletal, and gynecological diseases. This study was aimed to investigate the association between serum Vitamin B12 (vitB12), body mass index (BMI), and nutritional status among obese women. Methods: This cross-sectional study enrolled consecutive female subjects. The consumptions of red meat, fish, bovine liver, egg, and mushroom were recorded. According to the Dietary Reference Intakes, the patients were categorized as insufficiency and sufficiency. Three cutoff points were defined for vitB12 status: (1) Deficiency if vitB12 is < 200 pg/mL; (2) insufficiency if vitB12 is 250-350 pg/mL, and (3) sufficient if vitB12 is >= 350 pg/mL. According to BMI, the patients were assigned to nonobese and obese groups. BMI, serum vitB12 level, consumptions of red meat, fish, bovine liver, egg, and mushroom were evaluated and compared between two groups. Results: Mean level of vitB12 was 247.8 +/- 10.4 pg/mL and significantly associated with consumption of egg (P = 0.031), bovine liver (P = 0.004), mushroom (P = 0.040), and red meat (P = 0.003). VitB12 was significantly higher in nonobese than obese group (282.5 +/- 106.8 vs. 242.5 +/- 107.5 pg/mL, P = 0.001). The ratio of vitB12 deficiency was significantly higher in obese than nonobese group (37.6% vs. 24.7%; P = 0.019). VitB12 level was negatively correlated with BMI (r = -0.155; P < 0.001), but not insulin resistance (r = -0.172; P = 0.062). Conclusion: Obesity was associated with low level of vitB12 in obese women, and more likely to be vitB12 deficient. Consumption of certain types of food contributes to increase vitB12 level.
