[Risk factors for osteoporosis in postmenopausal women from Guadalajara, Jalisco].

OBJECTIVE
To know risk factors and the frequency of osteoporosis (OP) in postmenopausal women.


MATERIALS AND METHODS
Bone mineral density was measured in lumbar spine of 513 postmenopausal women from a hospital of Guadalajara, Jalisco during 2007-2008. The cutoff points of the associated variables were obtained by ROC curves and odds ratio (OR) by logistic regression.


RESULTS
The 25.2% (95%CI 21.44-28.96) of the women was OP. The variables associated with OP and cutoff points were age >60 years, weight <71 kg, height <1.54 m and BMI <29.2 kg/m(2), with OR greater than 3.19 (p<0.0001).


CONCLUSIONS
It is recommended setting cutoff points to estimate risk factors for OP more accurately in each population.
