Abstract
Aim
To evaluate the quality of life in postmenopausal women and its correlation with bone mineral density.
Study design
Cross-sectional study.
Duration of the study
October 2012 to September 2014.
Settings
Physical Medicine and Rehabilitation Department, Regional Institute of Medical Sciences, Imphal.
Study population
Postmenopausal women who attended the department during the study period.
Materials and Methods
Quality of life was assessed using WHOQOL-BREF questionnaire, a validated brief version of the WHOQOL-100. Bone mineral density (BMD) in the lumbar spine, femoral neck and trochanter were measured using dual energy x-ray absorptiometry (DEXA) scan – GE Lunar model.
Results
A total of 125 patients were studied. The mean t-scores in lumbar spine, femoral neck and trochanter were -2.550 ± 1.209, -1.831 ± 0.921 and -1.621 ± 1.064 respectively. The mean BMD (g/cm2) in lumbar spine, femoral neck and trochanter were 0.867 ± 0.144, 0.789 ± 0.131 and 0.682 ± 0.139 respectively. The mean overall WHOQOL score was 57.68±10.07. There were statistically significant positive association of WHOQOL score with the BMDs in lumbar spine, femoral neck and trochanter (p < 0.05). Multivariate regression showed significant relation of overall WHOQOL score with BMD lumbar spine (b=0.229; R2=0.119), BMD femoral neck (b=0.285; R2=0.129), and BMD trochanter (b=0.245; R2=0.119).
Conclusion
BMDs in the lumbar spine, femoral neck and trochanter had a positive correlation with quality of life scores. BMD also had a good predictive value in determining the quality of life in postmenopausal women.
