    Determining the relationship between dietary iodine intake, urinary iodine excretion and thyroid functions in people with type 2 diabetes mellitus
    (2020) Karakaya, Rahime Evra; Saka, Mendane; Ozdemir, Didem; 32267361
    Objective: 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. Materials and methods: Iodine nutritional status was determined by a one day 24-h dietary recall and food-frequency questionnaire. Iodine status was determined by urinary iodine excretion with morning urine sample. Results: Iodine intake according to one day 24-h dietary recall was lower in T2DM patients [94.8 (76.0-112.0) mu g] than people in control group [137.1 (123.1-165.4) mu g] (p < 0.05). Iodine intake determined by food-frequency questionnaire rich in iodine was lower in T2DM patients [93.1 (84.4-113.9) mu g] than people in control group [140.2 (125.1-166.1) mu g] (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). Conclusion: With this respect, the results showed that while planning medical nutrition therapy for diabetic individuals, the risk of iodine deficiency should be considered.

    Is neck circumference measurement an indicator for abdominal obesity? A pilot study on Turkish Adults
    (2014) Saka, Mendane; Turker, Perim; Ercan, Aydan; Kiziltan, Gul; Bas, Murat; 25352874
    Background: Neck circumference (NC) measurement is one of the simple screening measurements which can be used as an index of upper body fat distribution to identify obesity. Objectives: The aim of this study was to determine the relationship between neck circumferences and obesity. Methods: A total 411 volunteer adults participated in this study (174 men, 237 women). A questionnaire which consisted of anthropometric measurements and demographic features was used. Patients with NC >= 37 cm for men and >= 34 cm for women require evaluation of overweight status. Results: The percentages of the men and women with BMI >= 25kg/m(2) were 55.2% and 27.0% respectively and with high neck circumferences were 85.1% and 38.8%, respectively. The percentages of the men and women with high waist circumference were 31.6% and 79.3%, respectively. In both gender there were positive significant correlations between neck circumference, body weight (men, r=0.576; women, r=0.702; p=0.000), waist circumferences (men, r=0.593; women r=0.667; p=0.000), hip circumferences (men, r=0.568; women, r=0.617; p=0.000) and BMI (men, r=0.587; women, r=0.688; p=0.000). Conclusions: This study indicates that NC was associated with body weight, BMI, waist and hip circumferences and waist/hip ratio for men and women. A significant association was found between NC and conventional overweight and obesity indexes. NC was associated with waist/hip ratio for men and women.
