Bone Mineral Density In Male population: Association With Dietary Calcium Intake And Blood reassure

Abstract

This study was designed to evaluate bone mineral density (BMD) in an Iranian male population. Relationships between BMD, dietary calcium intake and blood pressure were assessed as well. An ethnically homogenous sample of 214 healthy men, inhabitants of Tehran, was studied. BMD measurements were done by dual x-ray absorptiometry using a Lunar DPXMD densitometer (Lunar, 7164, USA) at lumbar spine (L2-L4) and different femoral regions. Systolic (SBP) and diastolic (DBP) blood pressure were measured using an MPC-350 sphygmomanometer. Physicians collected demographic data and participants' dietary calcium intake were determined by using food frequency questionnaires. After adjusting for age, BMI, dietary Ca and exercise history, multiple linear regression models showed that DBP was negatively related to femoral neck BMD (β= - 0.145, p= 0.032). SBP was correlated with femoral neck (r=-0.171, p=0.012) and Ward's (r=-0.186, p=0.006) BMD but not after adjusting for possible confounders. Dietary calcium was positively associated with total femoral and femoral neck BMD and BMC. Further studies are needed to determine whether elevated blood pressure is causally related to the development of low bone mass.
