OBJECTIVE: To correlate @entity79 ( @entity79 ) in @entity1 with primary hypoestrogenism caused by 46,XX pure @entity444 or @entity2689 with age, age at @entity172 therapy initiation, length of @entity172 use, and body mass index (BMI). DESIGN: Cross-sectional study. SETTING: Academic tertiary-care hospital. @entity1 (S): Thirty-eight @entity1 , aged 16 to 35 years (mean, 24.6 years), affected by these @entity74 . INTERVENTION(S): Measurement of lumbar spine and femoral neck @entity79 using double x-ray absorptiometry. The results were correlated with the control variables by using Pearson's coefficient of correlation. Variables associated with @entity79 were evaluated by multiple linear regression analysis. MAIN OUTCOME MEASURE(S): Bone mineral density. RESULT(S): Bone mineral density of the lumbar spine showed that 90% of the @entity1 presented @entity2331 or @entity170 . The femoral neck was affected in 55% of these @entity1 . The length of @entity172 therapy and the BMI showed a positive association with @entity79 at the lumbar spine and femoral neck, respectively. CONCLUSION(S): @entity1 affected by pure @entity444 or @entity2689 presented a marked decrease in @entity79 of the lumbar spine and femoral neck. Medical attention for their diagnosis and early hormone replacement therapy are advised.
