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.
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; 26958017
Background: 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.
The Psychometric Properties of The Child Feeding Questionnaire (CFQ) in Turkey
(2014) Camci, Nurdan; Bas, Murat; Buyukkaragoz, Aylin Hasbay; 24656946
The purpose of this study was to test the reliability and validity of the Child Feeding Questionnaire (CFQ) among Turkish parents. The questionnaire was administered to 490 participants. Construct validity was assessed by principal component factor analysis with varimax rotation and reliability was tested by Cronbach's alpha coefficient. For testing criterion-related validity, EAT-40 with DEBQ was also administered to 490 participants. Results showed the presence of seven major factors (perceived responsibility, perceived parent weight, perceived child weight, concern about child weight, pressure to eat, monitoring and restriction) with loadings similar to those of the original questionnaire. Seven subscales of the CFQ had higher internal consistency and test-retest reliability. This study clearly demonstrates the factorial validity and the reliability of a Turkish version of the CFQ.
