T. Douchi et al., RELATIONSHIP BETWEEN BODY-MASS INDEX AND TRANSVAGINAL ULTRASONOGRAPHIC ENDOMETRIAL THICKNESS IN POSTMENOPAUSAL WOMEN, Acta obstetricia et gynecologica Scandinavica, 77(9), 1998, pp. 905-908
Objective. To investigate the relationship between body mass index (BM
I) and transvaginal ultrasonographic endometrial thickness. Materials
and methods. Two hundred and twelve postmenopausal Japanese women (mea
n age, 62.1+/-8.0 years; range 47-85) with histologically proven norma
l endometrium and with endometrial thickness more than 1.0 mm were stu
died. Baseline characteristics including age, years since menopause, a
nd BMI were recorded for each subject. The relationship between sonogr
aphic endometrial thickness and baseline characteristics was assessed
in each subject. Results. BMI was significantly correlated with endome
trial thickness (r=0.40, p<0.001), but age and years since menopause w
ere not correlated. On stepwise regression analysis only BMI was still
associated with endometrial thickness (R-2=0.16, p<0.001). Conclusion
. Sonographic endometrial thickness differs with BMI in postmenopausal
women. Higher BMI is associated with greater endometrial thickness.
