Low serum 25(OH)D levels are assocıated to hıgher BMI and metabolic syndrome parameters in adult subjects in Turkey.Afr Health Sci. 2015 Dec; 15(4):1161-9.AH
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.
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.
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).
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.
