BONE MINERAL DENSITY AND ITS ASSOCIATED FACTORS IN VIETNAMESE WOMEN OVER 40 YEAR OLD AT UNIVERSITY OF MEDICINE AND PHARMACY HOSPITAL
Main Article Content
Abstract
Background: Low measured bone mineral density (BMD) in clinical settings is an indirect indicator of osteoporosis and fracture risk. Objectives: To evaluate the mean BMD at the lumbar spine and femoral neck and the correlation between BMD and some associated factors in women over 40 years. Materials and Methods: A prospective cross-sectional study was conducted. The study group included 168 healthy women aged over 40 years having annual health surveillance at Can Tho University of Medicine and Pharmacy Hospital. BMD was measured at both lumbar spine and femoral neck using dual-energy X-ray absorptiometry (DEXA) from 12/2020 to 9/2021. Results: The results recorded that the mean BMD at the lumbar spine and femoral neck were 0,92±0,2g/cm2 and 0,84±0,15g/cm2, respectively. BMD at the lumbar spine and femoral neck had significant positive correlation with height (r=0,353, p<0,001; r=0,394, p<0,001), weight (r=0,435, p<0,001; r=0,414, p<0,001), BMI (r=0,33, p<0,001; r=0,284, p<0,001) while having significant negative correlation with age (r=-0,609, p<0,00; r=-0,561; p<0,001), time elapsed since menopause-TESM (r=-0,495, p<0,001; r=-0,523; p<0,001), and number of giving birth (r=-0,381, p<0,001; r=0,268, p<0,001). Conclusions: The mean BMD at the lumbar spine and femoral neck which had a significant correlation with age, TESM, number of giving birth, height, weight and BMI were relatively high.
