Assessment of bone mineral density and bone metabolism in young men with obstructive sleep apnea: a cross-sectional study

Table 5 Stepwise multiple regression analysis of all patients using BMD at the lumbar spine (L1–L4), the femoral neck and hip total as dependent variables

Dependent variable	Independent variable	β	p values
Lumbar L1–L4 BMD	LaSO₂	0.340	0.008*
(R² = 0.116, P = 008*)
Femur neck BMD	LaSO₂	0.304	0.037*
(R² = 0.156, P = 016*)	BMI	0.393	0.008*
Hip total BMD	BMI	0.720	0.002*
(R² = 0.519, P = 002*)

OSA Obstructive sleep apnea, BMD Bone mineral density, LaSO₂ Lowest O₂ saturation, BMI Body mass index, *p was considered statistically significant
