Introduction: Anthropometric parameters are easy and quickly methods of assess risks of many diseases.

Aim: The purpose of this study was to assess the correlation between calf circumference index, selected anthropometric (such as BMI, BAI, WHR, WHtR index) and biochemical parameters (such as concentration of 25(OH)D3, lipid profile, fasting glucose) among patients over 60 years.

Materials and methods: Cross-sectional study was done in a group of 123 patients hospitalized in the geriatric department in 2013–2015 (66% of the group were women, n=81). The study included patients above 60 years, without oral supplementation of vitamin D₃ 3 months before hospitalizations, without chronic kidney and liver diseases. Anthropometric parameters were measured in the morning, in light clothes in accordance with generally accepted methodology. Results of biochemical parameters were red from the patients’ medical records. The obtained data were statistically analyzed using STATISTICA 10PL. α=0.05.

Results: Mean age was 75.66±7.47 years. The average value of calf circumference index was 34.58±4.25 cm. The average BMI was 27.44±5.04 kg/m²; WHR 0.95±0.08; WHtR 0.61±0.08; BAI 33.38±6.06%. The mean concentration of 25(OH)D₃ was 15.35±6.65 ng/ml; fasting glucose 110.93±50.12 mg/dl; total cholesterol 204.32±51.21 mg/dl; HDL cholesterol 57.09±19.94 mg/dl; LDL cholesterol 125.82±42.85 mg/dl; triglycerides 115.87±57.05 mg/dl. There were observed positive correlation between calf circumference index and 25(OH)D3 (R=0.23; P=0.0266); triglycerides (R=0.30; P=0.0007); BMI (R=0.75; P<10⁻⁶); WHR (R=0.47; P<10⁻⁶); as well as BAI (R=0.30; P=0.0008). There were not observed statistically significant correlation of calf circumference index in relation to fasting glucose (R=0.13; P=0.1393); total cholesterol (R=0.13; P=0.1558); HDL cholesterol (R=−0.09; P=0.3264); LDL cholesterol (R=0.11; P=0.2233).

Conclusions: The study indicates that the measurement of calf circumference is an easy and fast methods which allow the assessment of concentration 25(OH)D3 in group patients above 60 years.
