A Study of Bone Mineral Density and Its Determinants in Type 1 Diabetes Mellitus

Figure 1

Correlation curves with coefficients of total body and lumbar spine BMD 𝑧 score with physical activity as metabolic equivalent time (MET), glycated haemoglobin (HbA1c), and insulin-like growth factor-1 (IGF-1) standard deviation score (SDS).

(a) Correlation of total body BMD 𝑧 score with physical activity 𝑟=0.58; 𝑃<0.05

(b) Correlation of lumbar spine BMD 𝑧 score with physical activity 𝑟=0.54; 𝑃<0.05

(c) Correlation of total body BMD 𝑧 score with HbA1C 𝑟=−0.75; 𝑃<0.05

(d) Correlation of lumbar spine BMD 𝑧 score with HbA1C 𝑟=−0.74; 𝑃<0.05

(e) Correlation of total body BMD 𝑧 score with IGF-1 (SDS) 𝑟=0.71; 𝑃<0.05

(f) Correlation of lumbar spine BMD 𝑧 score with IGF 1 (SDS) 𝑟=0.63; 𝑃<0.05
