[Menopause and ultrasonographic measurements of calcaneus].
BACKGROUND
In Mexico, calcaneal ultrasound measurements -bone mineral density (BMD), broadband ultrasound attenuation (BUA), speed of sound (SOS), ultrasonic quantitative index (QUI)- and their differences in regards to menopause have not been documented.


METHODS
It was carried out a cross-sectional study in 862 women from 20 to 90 years old, incorporated through consecutive sample, who were users of the Sistema para el Desarrollo Integral de la Familia (DIF) in Morelos. Sociodemographic, reproductive and life style factors were identified. BMD, BUA, SOS and QUI were measured with quantitative ultrasound (QUS), using a Sunlight Omnisense 7000 S device. Adjusted differences in the mean of these measurements were estimated between pre and postmenopausal women through multiple linear regression.


RESULTS
The medians were: BMD, 0.455 g/cm² (IQR, interquartile range = 0.378, 0.538); BUA, 66.0 dB/mHz (IQR = 54.3, 78.1); SOS, 1530.7 m/s (IQR = 1509.8, 1551.7); QUI = 83.7 units (IQR = 71.1, 96.6). In postmenopausal women, adjusted mean for BUA was -4.34 dB/mHz (CI 95 % = -8.23,-0.43); for SOS, -4.26 m/s (CI 95 % = -13.82, 5.30) ; for QUI, -4.42 units (CI 95 % = -8.64,-0.19).


CONCLUSIONS
This report increases information about the clinical applicability of QUS. SOS in calcaneus does not reflect changes related with menopause.
