Abstract(s)
Osteoporosis is a systemic skeletal disease that has great influence on functional independence and
quality of life, leading to reduced bone mass, microarchitectural deterioration, increased bone fragility, bone
fractures with minimal trauma, decreased bone mineral density and decrease bone quality. This quality is defined
by the bone health of it and is closely related to physical activity and body composition, genetic and hormonal
factors and nutrition. Under normal conditions, bone mineral density evolves, increased up to 27 years, leveling up
to 40. From here begins to decrease and there is a sharp decline in the menopausal stage and after it keeps a
sharp downward trend. Thus we aim to evaluate the physical condition of postmenopausal osteoporotic women,
assessing their functional status, different manifestations of strength and body composition.
After approval by the Ethics Committee of the North Health Region, we identified women
diagnosed with osteoporosis by dual-energy bone densitometry (DEXA), which showed inclusion criteria and who
wanted to participate in the study of their own free will. After assessment of blood pressure and heart rate were
subjected to:
a) Demographic variables
b) Quality of life evaluated with the osteoporosis assessment questionnaire (OPAQ) – 1 to 5 points represented by
numeric scale from 1 to 5, in which 1 represents better quality of life and 5 represents poor quality of life
c) Tinetti Falls Efficacy Scale [1]
d) Physical activity: short version of IPAQ (International Physical Activity Questionnaire).
e) Functional capacity: timed up and go test; 30 sec sit to stand; unipodal balance eyes shut
f) Height: stadiometer Seca
g) Handgrip strength of both hands: Jamar
h) Key pinch strength with digital dynamometer Baseline
hand dynamometer
i) Body composition: bioelectric impedance on Tanita Ironman Body Composition Monitor
The 18 women studied have an average age of 66,8±6,4 years, 148,2±5,3 cm of height and 57,4±6,2
Kg of weight which represents a BMI of 26,2±3,3. In the OPAQ the evaluated women achieved 3,1±0,7 points
and in the FES achieved 79,3±21,1 points. In the IPAQ 14 women were with low level of physical activity and 4
with moderated physical activity (average physical activity of 387,5±294,9METs). The average result of the timed
up and go test was 9,4±2,7 seconds, in the 30 sec sit to stand was 10,1±2,9 repetitions and in the unipodal
balance test was 4,1±6,9 seconds. When evaluating strength, we found 16,8±6,4 Kg/f for right handgrip strength
and 16,2±5,8 Kg/f for left handgrip strength. When evaluating key pinch strength we found 6,6±5,0 Kg/f and
6,3±5,2 Kg/f for the right and left hand, respectively. Analyzing the body composition average values, we have
33,6±6,0% for total body fat, 47,5±4,3% to body water, 2,0±0,2Kg to bone mass and 36,2±3,2 Kg to muscular
mass. Once established correlations between different variables, we can highlight some of the most important:
®
Weight correlates with total body fat (0,561*) and with body water (-,470*);
BMI correlates with average OPAQ (0,529*), total body fat (0,732**) and body water (-0,709**);
timed up and go test correlates with average age (0,633**), sit to stand (-0,583*), handgrip right and left (-
0,581*; -0,504*)The participants in this study show similar values when compared with the population with similar
characteristics. The BMI value means that the participants are averagely overweight. Most of the women of the
study have reduced physical activity levels and none of them have high physical activity levels. We also can
conclude that weight as an important role on body composition and the timed up and go test is an easy and cheap
test that gives us much information about the physical functioning of these osteoporotic postmenopausal women.
