Summary:
Introduction- Osteoporosis is a common disease of
postmenopausal women and is responsible for considerable
morbidity and mortality. The most important single
determining factor is low bone mass. Generally accepted risk
factors of osteoporosis in women are low body weight, age,
low physical activity and cigarette smoking. The effect of
parity is controversial.
Objective-The main objective of the study was to assess the
influence of parity on bone mineral density among the
postmenopausal women.
Methods-In this study total 75 postmenopausal women aged
51-70 years of with parity 1-13 were studied. Parity was
described as the number of births reported by the women. In
Journal of Bangladesh College of Physicians and Surgeons
Vol. 33, No. 2, April 2015
this study T score of BMD of different bony sites lumber
vertebrae and femur were analyzed. BMD were measured in
the Institute of Nuclear Medicine at BSMMU. Correlations
between BMD values with parity were detected.
Results- The mean age of the patients was 60 years with a
standard deviation of ±9.32 years. All patients were within
51 to 70 years age range. A significant negative correlation
was found in present study between parity and the T score
measurement results obtained from L2, L3, L4, L2-4, Femur
neck, Trochantor and Ward’s triangle. This shows mean Tscore
of BMD were more negative as number of parity
increases.
Key words: BMD. Postmenopausal women, Parity.
