Objective: Previous studies indicate that obesity is associated with a higher risk of experiencing hot flushes in mid-life women. The reasons for this association are unknown, although altered hormone levels have been associated with both hot flushes and obesity. Thus, this current study tested the hypothesis that obesity is associated with hot flushes in mid-life women through a mechanism involving levels of total and free androgen, free estrogen, progesterone, and sex hormone binding globulin (SHBG)., Methods: Women aged 45-54 years were recruited from Baltimore and its surrounding counties. Each participant (n=628) was weighed, measured, completed a questionnaire, and provided a blood sample that was used to measure estradiol, estrone, testosterone, androstenedione, dehydroepiandrosterone sulfate, progesterone, and SHBG., Results: Obese mid-life women (body mass index (BMI)>or=30.0 kg/m2) had significantly higher testosterone, and lower estradiol, estrone, progesterone, and SHBG levels than normal-weight mid-life women (BMI

Objective: Recent studies suggest that ovarian volume and antral follicle numbers may be sensitive, specific, and early indicators of menopausal status. The accuracy of these markers, however, has not been compared directly to more traditional markers [age and follicle-stimulating hormone (FSH) levels]. Thus, the purpose of this study was to test whether ovarian volume and antral follicle counts are more sensitive and specific markers of menopausal status than age or FSH levels., Design: Premenopausal (n = 34) and postmenopausal (n = 25) women between 40 and 54 years old received a transvaginal ultrasound for determination of ovarian volume and antral follicle numbers, provided blood for measurement of FSH levels, and completed a questionnaire. FSH levels, age, ovarian volume, and antral follicle numbers were compared using t tests. Receiver operating characteristic curves were generated to evaluate the sensitivity and specificity of each marker., Results: Postmenopausal women had significantly higher FSH levels (p < or = 0.0001), smaller ovarian volumes (p < or = 0.002), and fewer antral follicles (p < or = 0.002) than premenopausal women. Ovarian volume and antral follicle numbers had similar sensitivity (27.3-100%) and specificity (3.4-92.9%) in indicating postmenopausal status as FSH levels and age., Conclusion: These data suggest that ovarian volume and antral follicle numbers may be useful indicators of menopausal status.

Objective: The purposes of this study were to (1) examine whether ovarian volume differs by age and menopausal status in healthy women; (2) evaluate whether ovarian volume could be a sensitive and specific predictor of menopausal status; and (3) assess whether ovarian volume is affected by cigarette smoke, oral contraceptives (OCs), and hormone replacement therapy (HRT)., Design: Each participant (527 women) completed an extensive in-home interview that assessed age, menopausal status, smoking history, OC use, and HRT use. Each participant also received a transvaginal ultrasound that measured ovarian volume. Geometric means for ovarian volume were compared between premenopausal and postmenopausal women using t tests. Tests for trends were conducted using linear regression analyses., Results: Ovarian volume declined with age (p < or = 0.0001) and also differed by menopausal status; postmenopausal women had smaller ovarian volumes than premenopausal women of the same age (p < or = 0.0001). Ovarian volume was not associated with smoking history or HRT use. However, it was significantly smaller in current users of OCs compared with past users of or those who never used OCs (p < or = 0.0001). Ovarian volume was a sensitive and specific predictor of postmenopausal status., Conclusions: The data suggest that age, menopausal status, and OC use may be determinants of ovarian volume. They also suggest that ovarian volume may be useful for predicting menopausal status in women.

There are limited data on the factors associated with menopausal hot flashes, a common and potentially morbid condition. The objective of this study was to identify predictors of menopausal hot flashes. To meet this objective, 233 naturally perimenopausal or post-menopausal women (ages 45-65) attending a large urban hospital center primary care clinic, mammography unit, or women's health practice were enrolled. The women responded to a self-administered questionnaire assessing selected demographic factors, reproductive history, and behavioral factors. Sixty-seven percent of respondents experienced hot flashes, with 63% reporting frequent hot flashes (at least one hot flash per day) and 60% with hot flashes describing the hot flashes as severe. Women with hot flashes were significantly more likely to have mothers who experienced hot flashes (OR = 4.4, CI = 2.0-10.0) or to be smokers (OR = 2.0, CI = 1.2-3.5). There were no statistically significant associations between hot flashes and other selected demographic, reproductive, or behavior characteristics. These results reveal that menopausal hot flashes are associated with a maternal history of hot flashes as well as with cigarette smoking. These results may help physicians to counsel their patients about smoking cessation.

To examine racial/ethnic differences in breast cancer mortality over time by menopausal status, data from published U.S. Vital Statistics tables (1950-1992) and the Surveillance, Epidemiology, and End Results Program of the National Cancer Institute (1973-1991) were used to calculate age-adjusted breast cancer mortality and incidence rates. Overall, breast cancer mortality rates for white women were relatively stable from 1950 to 1992. In contrast, breast cancer mortality rates for black women increased during this period. Among premenopausal women there was no difference in breast cancer mortality between black and white women from 1950 to about 1975. However, after 1975, mortality rates in black premenopausal women increased, whereas those in white women decreased. Among postmenopausal women, breast cancer mortality was substantially lower in blacks than in whites in 1950. Between 1950 and 1992, rates in blacks increased and eventually exceeded rates in whites, which remained stable during this period. This excess in breast cancer mortality in black women is not explained by changes in breast cancer incidence rates. There is an unexplained epidemic of breast cancer mortality in black women that appears to differ somewhat by menopausal status. Reasons for temporal increases in breast cancer mortality seen only among black women need to be identified, as do reasons for the heterogeneity of trends by menopausal status.

Objective Studies have reported a decline in sexual functioning among women undergoing the menopausal transition. Few studies, however, have examined the associations between hormones and sexual dysfunction during this time period. Therefore, the purpose of this study was to examine the associations between participant characteristics and endogenous hormones with sexual functioning in mid-life women. Methods Data were analyzed from a community-based sample of 441 women aged 45-54 years who stated that they were sexually active at the time of the study. Each participant completed a survey that included questions pertaining to sexual functioning and provided a blood sample that was used to measure estrogen and androgen concentrations. Results Among women who reported being sexually active, poorer self-reported health and the experiencing of depressive symptoms were significantly associated with not being satisfied with sexual relations after adjustment for other covariates. None of the hormones examined were significantly associated with overall sexual satisfaction. However, statistically significant associations between both total testosterone levels and the free testosterone index with satisfaction with the frequency of sexual relations were observed. Conclusions Our findings indicate that the experiencing of depressive symptoms and the reporting of poor overall health are important correlates of sexual dysfunction. Further, our results suggest that higher total and free testosterone levels are significantly associated with a desire for increased frequency of sexual relations among mid-life women.
