Abstract
OBJECTIVE In this study, we aimed to develop education to assist BRCA mutation carriers in making informed decisions about HRT in the context of risk-reducing surgery, while simultaneously clarifying their treatment-specific values and reducing decisional conflict. METHODS We enrolled premenopausal BRCA mutation carriers ages 19-49 without prior cancer or risk-reducing salpingo-oophorectomy to structured interviews in which they reviewed education about the risks and benefits of HRT. Materials included literature-derived data demonstrating associations between HRT and commonly considered health outcomes (breast cancer, vasomotor symptoms, sexual functioning, cardiovascular disease, osteoporosis, and blood clots). Participants completed the 16-item Decisional Conflict Scale (DCS) before and after education, communicated their preferences by rating and ranking the six outcomes, and provided feedback to inform iterative revisions of the educational content. RESULTS 25 participants completed interviews. DCS scores decreased significantly from 54.6 to 22.8 following education (p < 0.001); sub-scores for uncertainty (71.7 to 37.3), informed (71.7 to 15.3), values clarity (53.7 to 17.0), effective decision (44.2 to 25.5), and support (35.0 to 17.7) also decreased significantly. Participants ranked cardiovascular disease as the most important outcome to consider, followed by breast cancer, osteoporosis, blood clots, decline in sexual function, and hot flashes. Participants with prior mastectomy (N = 10) ranked breast cancer as the most important outcome 25% of the time, compared to 80% in participants without mastectomy (N = 15). CONCLUSION Following education, BRCA mutation carriers had significantly less decisional conflict regarding the choice to use HRT. This pilot study was successful in generating a prototype educational aid for further testing.

Abstract
path_BRCA 1/2 increases a woman's lifetime risk of breast and ovarian cancer. Interventions can be offered which manage cancer risk; annual breast screening from age 30, chemoprevention and, once a woman's family is complete, risk-reducing surgery. The latter is the most effective method of reducing cancer in path_BRCA carriers; salpingo-oophorectomy reduces breast and ovarian cancer, respectively, by up to 50% and 95%. Factors affecting a woman's decision to undergo risk-reducing surgery are complex; dominant factors include risks of surgery, effect on cancer outcomes and menopausal sequelae. Specific information relating to hormone replacement and non-hormonal alternatives are an important consideration for women but, are often overlooked. Informative counselling is required to enable satisfaction with the chosen intervention whilst improving survival outcomes. This review paper outlines the current data pertaining to these decision-making factors and provides a proforma to enable effective counselling.

Abstract
BACKGROUND Digital health interventions are efficacious in health-promoting behaviors (eg, healthy eating and regular physical activity) that mitigate health risks and menopausal symptoms in midlife. However, integrated evidence-based knowledge about the mechanisms of change in these interventions is unclear. OBJECTIVE This systematic review aimed to evaluate studies on behavior change techniques (BCTs) and mechanisms of change in digital health interventions aimed at promoting health-enhancing behaviors in midlife women (aged 40-65 years). METHODS A systematic literature search of the electronic databases PubMed, Web of Science, PsycINFO, and Cochrane Central Register of Controlled Trials in the Cochrane Library was conducted. In total, 2 independent reviewers selected the studies for inclusion, extracted data, and completed BCT mapping of eligible studies. The mechanism of action and intervention functions of eligible studies were evaluated using the behavior change wheel framework. Reporting of psychological theory use within these interventions was explored using the Theory Coding Scheme. Mode of delivery, psychological theory, and BCTs were presented as descriptive statistics. RESULTS In total, 13 interventions (including 1315 women) reviewed used 13 (SD 4.30, range 6-21) BCTs per intervention on average. The "Shaping knowledge" and "Repetition and substitution" behavior change categories were used most frequently, with 92% (12/13) of the interventions implementing at least one of the BCTs from these 2 categories. Only 13.98% (169/1209) of the 93 available BCTs were used, with "Instructions on behaviour" most frequently used (12/13, 92%). The behavior change wheel mapping suggests that half of the intervention content aimed to increase "Capability" (49/98, 50% of the intervention strategies), "Motivation" (41/98, 42%), and "Opportunity" (8/98, 8%). "Behavioural Regulation" was the most frequently used mechanism of action (15/98, 15%), followed by increasing "Knowledge" (13/98, 13%) and "Cognitive and Interpersonal skills" (10/98, 10%). A total of 78% (7/9) of the intervention functions were used in the studies to change behavior, primarily through "Enablement" (60/169, 35.5%), whereas no study used "Restriction" or "Modelling" functions. Although 69% (9/13) of the interventions mentioned a psychological theory or model, most (10/13, 77%) stated or suggested rather than demonstrated the use of a theoretical base, and none reported explicit links between all BCTs within the intervention and the targeted theoretical constructs. Technological components were primarily based on web-based (9/13, 69%) modes of delivery, followed by phone or SMS text message (8/13, 62%) and wearables (7/13, 54%). CONCLUSIONS The findings of this review indicate an overall weak use of theory, low levels of treatment fidelity, insignificant outcomes, and insufficient description of several interventions to support the assessment of how specific BCTs were activated. Thus, the identified limitations in the current literature provide an opportunity to improve the design of lifestyle health-enhancing interventions for women in midlife.

Osteoporos Int 2022; 33:1677-1686.

Abstract
UNLABELLED The present study provides evidence that women who underwent hysterectomy without oophorectomies are at a higher risk of osteoporosis and bone fractures than the general population. Early interventions for these susceptible women may help to delay or reduce the risk of osteoporosis and bone fractures. INTRODUCTION Mounting studies have shown that patients with hysterectomy are at high risk of developing osteoporosis or bone fractures, but the evidence from all the relevant studies has not been previously synthesized. The present study aims to investigate whether women with hysterectomy without oophorectomies have a prominently higher prevalence of osteoporosis or fractures than healthy subjects. METHODS Four electronic databases were systematically searched to identify the eligible studies. The combined effect was assessed by calculating the relative risk (RR) with a 95% confidence interval (CI). More methodologies for this study were available in the PROSPERO (ID: CRD42021227255). RESULTS Finally, three observational studies offering osteoporosis cases and two retrospective studies reporting fracture cases were included. One eligible study has provided independent data from three groups of fractures. Synthetic results revealed that hysterectomy without oophorectomies was significantly associated with an increased risk of osteoporosis as compared to the general population (combined RR from three studies = 1.47, 95%CI 1.253 to 1.725, P < 0.001; heterogeneity, I2 = 76.2%, P = 0.015). Consistently, the prevalence of fractures was also significantly higher in patients with hysterectomy without oophorectomies than in healthy controls (pooled RR from four studies = 2.333, 95%CI: 1.314 to 4.144, P = 0.004; heterogeneity, I2 = 92.3%, P < 0.001). CONCLUSIONS This is the first study to quantify the association between hysterectomy without oophorectomies and osteoporosis/fracture risk through a meta-analysis and has subsequently confirmed its positive relationship. Additional large-sample rigorously prospective cohorts are still warranted to validate the present evidence.

Abstract
Age at menopause has been shown to have an impact on bone and heart health, with younger menopause age consistently associated with a higher risk of cardiovascular disease, osteoporosis, and fracture. These risks are particularly high increased among women who encountering menopause at an early age, including women with premature ovarian insufficiency (POI) and early menopause, due to a prolonged period of oestrogen deprivation. Several interventions are suggested to optimise the bone and cardiovascular health of women with menopause including lifestyle modification, dietary supplements, hormonal, and non-hormonal therapies. Hormone therapy (HT) is indicated for women with POI. For women with early menopause, there is a paucity of evidence for the management of bone and cardiovascular health. For women beyond the average age of menopause, HT is not indicated solely for bone protection and cardiovascular health. In this group, screening for bone and heart disease, as well as primary and secondary prevention, should be undertaken in line with national and international guidelines.

Abstract
CONTEXT Menopause before age 45 is a risk factor for fractures, but menopause occurs at age ≥45 in ~90% of women. OBJECTIVE To determine, in women with menopause at age ≥45, whether (1) years since the final menstrual period (FMP) is more strongly associated with postmenopausal bone mineral density (BMD) than chronological age and (2) lower age at FMP is related to more fractures. DESIGN AND SETTING The Study of Women's Health Across the Nation, a longitudinal cohort study of the menopause transition (MT). PARTICIPANTS A diverse cohort of ambulatory women (pre- or early perimenopausal at baseline, with 15 near-annual follow-up assessments). MAIN OUTCOME MEASURES Postmenopausal lumbar spine (LS) or femoral neck (FN) BMD (n = 1038) and time to fracture (n = 1554). RESULTS Adjusted for age, body mass index (BMI), cigarette use, alcohol intake, baseline LS or FN BMD, baseline MT stage, and study site using multivariable linear regression, each additional year after the FMP was associated with 0.006 g/cm2 (P < 0.0001) and 0.004 g/cm2 (P < 0.0001) lower postmenopausal LS and FN BMD, respectively. Age was not related to FN BMD independent of years since FMP. In Cox proportional hazards regression, accounting for race/ethnicity, BMI, cigarette use, alcohol intake, prior fracture, diabetes status, exposure to bone-modifying medications/supplements, and study site, the hazard for incident fracture was 5% greater for each 1-year decrement in age at FMP (P = 0.02). CONCLUSIONS Years since the FMP is more strongly associated with postmenopausal BMD than chronological age, and earlier menopause is associated with more fractures.

Abstract
INTRODUCTION Parity has been suggested as a possible factor affecting bone health in women. However, study results on its association with bone mineral density are conflicting. METHODS PubMed, EMBASE, the Cochrane Library, and Korean online databases were searched using the terms "parity" and "bone mineral density", in May 2016. Two independent reviewers extracted the mean and standard deviation of bone mineral density measurements of the femoral neck, spine, and total hip in nulliparous and parous healthy women. RESULTS Among the initial 10,146 studies, 10 articles comprising 24,771 women met the inclusion criteria. The overall effect of parity on bone mineral density was positive (mean difference=5.97mg/cm2; 95% CI 2.37 to 9.57; P=0.001). The effect appears site-specific as parity was not significantly associated with the bone mineral density of the femoral neck (P=0.09) and lumbar spine (P=0.17), but parous women had significantly higher bone mineral density of the total hip compared to nulliparous women (mean difference=5.98mg/cm2; 95% CI 1.72 to 10.24; P=0.006). No obvious heterogeneity existed among the included studies (femoral neck I2=0%; spine I2=31%; total hip I2=0%). CONCLUSION Parity has a positive effect on bone in healthy, community-dwelling women and its effect appears site-specific.

Abstract
OBJECTIVE The purpose of the present study was to investigate the correlation between serum testosterone levels and bone mineral density (BMD) in postmenopausal women. MATERIALS AND METHODS The study group was made up of postmenopausal women admitted to our tertiary center. Serum calcium, phosphorus, albumin, parathyroid hormone (PTH), thyrotropin (TSH), 25-OH vitamin D, and total testosterone concentrations were measured. Subjects were categorized into three groups regarding bone mineral density (BMD) values: normal (n = 22), osteopenia (n = 21), and osteoporosis (n = 21). Subjects were also categorized into three groups according to serum testosterone levels: low testosterone (n = 10), normal testosterone (n = 42), and high testosterone (n = 12). RESULTS No significant difference was found for serum testosterone, TSH, calcium, phosphorus, albumin, PTH, and 25-hydroxyvitamin D levels among patients with normal BMD, osteopenia, and osteoporosis (p > 0.05). Lumbar spine, total femur, femoral neck, trochanteric, intertrochanteric, and Ward's triangle BMD values were similar for the different testosterone levels (p > 0.05). CONCLUSION There was no correlation between serum testosterone levels and patient age, body-mass index, or any measured BMD values. Given the findings in our study, which failed to demonstrate a statistically significant relationship between testosterone and BMD, adjustment of other risk factors for osteoporosis might have a more distinctive effect in this setting.

Abstract
During pregnancy and lactation, female physiology adapts to meet the added nutritional demands of fetuses and neonates. An average full-term fetus contains ∼30 g calcium, 20 g phosphorus, and 0.8 g magnesium. About 80% of mineral is accreted during the third trimester; calcium transfers at 300-350 mg/day during the final 6 wk. The neonate requires 200 mg calcium daily from milk during the first 6 mo, and 120 mg calcium from milk during the second 6 mo (additional calcium comes from solid foods). Calcium transfers can be more than double and triple these values, respectively, in women who nurse twins and triplets. About 25% of dietary calcium is normally absorbed in healthy adults. Average maternal calcium intakes in American and Canadian women are insufficient to meet the fetal and neonatal calcium requirements if normal efficiency of intestinal calcium absorption is relied upon. However, several adaptations are invoked to meet the fetal and neonatal demands for mineral without requiring increased intakes by the mother. During pregnancy the efficiency of intestinal calcium absorption doubles, whereas during lactation the maternal skeleton is resorbed to provide calcium for milk. This review addresses our current knowledge regarding maternal adaptations in mineral and skeletal homeostasis that occur during pregnancy, lactation, and post-weaning recovery. Also considered are the impacts that these adaptations have on biochemical and hormonal parameters of mineral homeostasis, the consequences for long-term skeletal health, and the presentation and management of disorders of mineral and bone metabolism.

Abstract
In addition to the common symptoms that occur after natural menopause, special considerations apply to women who have had their ovaries removed, particularly when oophorectomy occurs before age 45 years. Women with premenopausal oophorectomy have more severe and prolonged menopausal symptoms. Their risks of adverse mood, heart disease, excessive bone resorption, sexual dysfunction, and cognitive disorders are increased compared with the general population. Retention of the ovaries carries a survival benefit for women at low risk of ovarian malignancy. Women facing oophorectomy should understand the balance of risks and benefits in order to make an informed decision.

Bilateral oophorectomy at the time of hysterectomy for benign disease is commonly practiced in order to prevent the subsequent development of ovarian cancer or other ovarian pathology that might require additional surgery. At present, bilateral oophorectomy is performed in 78% of women aged between 45 and 64 years having a hysterectomy, and a total of approximately 300,000 prophylactic oophorectomies are performed in the USA every year. Estrogen deficiency resulting from pre- and post-menopausal oophorectomies has been associated with higher risks of coronary heart disease, stroke, hip fracture, Parkinsonism, dementia, cognitive impairment, depression and anxiety in many studies. While ovarian cancer accounts for 14,800 deaths per year in the USA, coronary heart disease accounts for 350,000 deaths per year. In addition, 100,000 cases of dementia may be attributable annually to prior bilateral oophorectomy. At present, observational studies suggest that bilateral oophorectomy may do more harm than good. In women who are not at high risk of developing ovarian or breast cancer, removing the ovaries at the time of hysterectomy should be approached with caution.

The use of depot-medroxyprogesterone acetate in contraception and its potential impact on skeletal health. Contraception 2009; 79:167-77. [PMID: 19185668 DOI: 10.1016/j.contraception.2008.10.016] [Citation(s) in RCA: 24] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2008] [Revised: 10/08/2008] [Accepted: 10/09/2008] [Indexed: 10/21/2022]
Abstract
BACKGROUND In the fall of 2007, the controversy about the contraceptive use of depot-medroxyprogesterone acetate (DMPA) and its potential impact on skeletal health reached the media in the province of Quebec, Canada, thereby becoming a matter of concern for the lay public and physicians. In order to discuss this subject openly, the National Institute of Public Health of Quebec (INSPQ) organized a scientific meeting on February 15, 2008, with targeted physicians delegated by their medical associations in the fields of general practice, obstetrics and gynaecology, rheumatology, orthopaedic surgery, physiatry and endocrinology. STUDY DESIGN Participants reviewed the scientific literature using the study classification method according to the level of evidence, reviewed published guidelines of medical societies and organizations on the subject and reached a consensus position. This manuscript presents a review of the literature and describes the consensus position of the targeted medical associations. RESULTS The consensus position adopted by all the targeted medical associations determined that DMPA was a cost-effective contraceptive option that must be considered in the light of the clinical situation and preference of each woman. Candidates for injectable contraception should be informed that the use of DMPA is associated with a slight decrease in bone mineral density (BMD), which is largely, if not completely, reversible. There should not be an absolute limit to the length of time that the DMPA contraceptive is used, regardless of the woman's age. Monitoring BMD is not recommended among users of DMPA for contraceptive purposes. Finally, the consensus statement declared that, although supplements of calcium and vitamin D are beneficial for skeletal health for women in general, such supplementation should not be recommended solely based on a woman's use of DMPA. CONCLUSION Given the scientific evidences, DMPA use remains a valid contraceptive option for women. Its potential impact on BMD must be balanced against the significant individual, familial and social consequences of unintended pregnancy.

Abstract
UNLABELLED Dehydroepiandrosterone (DHEA) may be useful in the treatment of postmenopausal osteoporosis (PMO). Our present study has found the preferable stimulatory effect of DHEA on bone, in contrast to the proliferative effects of estradiol (E2) on the endometrium and the uterus, which suggests that DHEA has greater potential clinical value than estrogens in prophylaxis and therapeutics for PMO. INTRODUCTION A series of findings raise the possibility that DHEA may be useful in the treatment of PMO. Our present study thus aimed at the differential effects of DHEA and E2 on bone and the uterus in ovariectomized mice as well as the involvement of aromatase, ERalpha, ERbeta, and AR in the effects. METHODS Ovariectomized and sham BALB/c mice were given daily treatment with either DHEA or E2 for three months, respectively. Bone mineral density was determined by DEXA after the last treatment. Mice were necropsied in 3 months after the treatment to analyze the ultrastructure of their femur osteoblasts (OBs) with a transmission electron microscope (TEM); DHEA, DHEA sulfate (DHEAS) and E2 levels were assayed by EIA; production in vitro of E2 in the uterus or tibia was assayed to evaluate the profile of P450arom activity; ERalpha and ERbeta mRNA levels in the uterus and tibia were determined by real-time PCR. The primary murine OBs were treated with DHEA and E2, respectively for 72 h. Real-time polymerase chain reaction (PCR) and western blot were carried out to evaluate aromatase, ERalpha, ERbeta and AR expression in OBs. RESULTS Both DHEA and E2 significantly improved BMD and OB ultrastructure; E2 but not DHEA has significantly increased uterus wet weight, endometrium epithelial and gland thickness. Dehydroepiandrosterone not only increased serum, femoral DHEA, DHEAS and E2 concentration, but also increased uterine DHEA and DHEAS other than E2 concentration in site, while E2 only increased serum, uterine and femoral E2 concentration, but failed to alter the concentrations of DHEA and DHEAS. Moreover, DHEA significantly increased tibia P450arom enzyme activity, while E2 increased uterine and tibia aromatase activity. Furthermore, DHEA increased uterine ERbeta and ERalpha, and ERbeta transcription in the tibia, while E2 increased ERalpha transcription in the uterus and tibia. Dehydroepiandrosterone increased aromatase, ERalpha, ERbeta and AR expression in OBs, and increased significantly, but E2 apparently decreased the ratio of ERbeta/ERalpha. CONCLUSIONS Although both DHEA and E2 augment BMD, the proliferative effects of E2 on the endometrium and uterus reflect the different modes of action on bone and the uterus, indicating that the preferable stimulatory effect of DHEA on bone appears to the more potential clinical values than estrogens in prophylaxis and therapeutics for PMO. But applicability of the findings from rodents in humans needs further study.

Influence of parity on bone mineral density and peripheral fracture risk in Moroccan postmenopausal women. Maturitas 2007; 57:392-8.

Abstract
UNLABELLED The aims of the study were to determine: (1) the relationship between parity and bone mineral density (BMD); (2) the relationship between parity and osteoporotic peripheral fractures. MATERIAL AND METHODS The group studied included 730 postmenopausal women. Patients were separated into four groups according to the number of fullterm pregnancies, group 1: nulliparae, group 2: one to three pregnancies, group 3: four to five pregnancies, and group 4: six and more pregnancies. Additionally, patients were separated into three groups according to their ages, as <50 years, 50-59 years and >or=60 years. RESULTS The median parity was 4 [0-20]. All the patients with parity greater than six had spine and hip BMD values significantly lower than values in the other groups (p<0.001). After adjustment for age and body mass index (BMI), decreased lumbar and total hip BMD were still associated to increased parity (analysis of covariance (ANCOVA), p=0.04 and 0.023, respectively). The relation between parity and lumbar BMD was highly significant among women aged <50 years (age-adjusted p=0.022), while there was no parity-spine BMD association in the other age groups. The relation between parity and hip BMD was seen only in the group 50-59 years (age-adjusted p=0.042). A positive history for peripheral fractures was present in 170 (23%) patients. There was relationship between parity and peripheral fractures neither in the whole population nor in the sub-groups according to age. DISCUSSION The present study suggests that the BMD of the spine and hip decreases with an increasing number of pregnancies, and this situation shows variations in different age groups. However, there was no correlation between parity level and peripheral fractures.

Abstract
OBJECTIVE To assess long-term fracture risk after hysterectomy, with or without oophorectomy. DESIGN Population-based, cohort study. SETTING Olmsted County, Minnesota. PATIENT(S) Women residing in Olmsted County (n = 9,258) who underwent hysterectomy in 1965-2002, compared to an equal number of age- and sex-matched community controls. INTERVENTION(S) Observational study of the effect of hysterectomy for various indications on subsequent fractures. MAIN OUTCOME MEASURE(S) Fractures of any type, and at osteoporotic sites (e.g., hip, spine, or wrist) alone, as assessed by electronic review of inpatient and outpatient diagnoses in the community. RESULT(S) Compared with controls, there was a significant increase (hazard ratio [HR], 1.21; 95% confidence interval [CI], 1.13-1.29) in overall fracture risk among the women with a hysterectomy, but osteoporotic fracture risk was not elevated (HR, 1.09; 95% CI, 0.98-1.22). Most hysterectomy indications were associated with fractures generally, although these were not often statistically significant. Only operations for a uterine prolapse were associated with osteoporotic fractures (HR, 1.33; 95% CI, 1.01-1.74). Oophorectomy was not an independent predictor of fracture risk (HR, 1.0; 95% CI, 0.98-1.15). CONCLUSION(S) Hysterectomy does not appear to pose much long-term risk for fractures, but the association of fractures with surgery for uterine prolapse deserves further attention.

Abstract
OBJECTIVE To review the data on the effect of early menopause on bone. Do women undergoing early menopause develop lower bone mineral density at an earlier age and do they have a higher incidence of osteoporotic fractures? Is there a difference on bone between women who undergo early natural menopause compared to women who have early menopause after oophorectomy? RESULTS The earlier in life that menopause occurs, the lower the bone density will be later in life. Low bone density is associated with a higher fracture rate, and several studies show a relationship between early menopause, oophorectomy, and an increase in osteoporotic fractures. CONCLUSIONS Early menopause is a risk factor for osteoporosis. Women with an early menopause should have bone density testing performed within 10 years of menopause so that osteopenia or osteoporosis will be diagnosed early and appropriate anti-resorptive therapy initiated.

Abstract
UNLABELLED Several studies have shown that low body mass index (BMI) is associated with low BMD and fractures. However, the results that have been published from studies on reproductive factors and BMD are extremely controversial, with some demonstrating a beneficial effect, while others show a detrimental impact of these factors on bone mass. OBJECTIVE To study the influence of several gynecological factors (years since menopause (YSM), age at menarche and gynecological age or reproductive life) simultaneously with anthropometric factors as determinants of bone mineral density (BMD) in healthy women older than 40. METHODS BMD was determined by dual energy X-ray absorptiometry (DXA) at the lumbar spine and femurs in women aged >40 randomly chosen from the population of Rabat with a cluster sampling method. RESULTS Four hundred and twenty-two healthy women older than 40 years were included in the study. The mean age was 57.2 years (8.4) [40-79] and the mean number of parities was 4.42 (2.9) [0-14]. Osteoporosis according to the classification of WHO (T-score<or=-2.5) was observed in 133 women (32.2%). The increase in the number of parities was associated to a larger body mass index and a lower BMD as well in the hips and the lumbar spine after adjustment for age. The comparison of groups of patients according to the age at menarche, the age at menopause or the period of fertility did not highlight an association with BMD. BMD at the lumbar spine and the hips was correlated negatively with age, YSM and parity and positively with BMI. Multivariate analysis showed that the determinant of BMD are BMI (OR=0.88; 95% CI: 0.83-0.92), parity (OR=1.10; 1.01-1.56) and YSM (OR=1.06; 1.03-1.10). CONCLUSION Bone loss in women older than 40 is a function of aging, parity and years since menopause; and there is a definite bone-protective effect of body mass weight. Further studies are required to evaluate the role of these parameters in the fracture risk.

Abstract
OBJECTIVE The aim of the study was to assess skeletal status in natural and surgically induced menopausal women regarding the presence of previous osteoporotic fracture. METHODS Ninety-three females after bilateral oophorectomy in mean age of 56.8+/-8.3y. (48 without and 45 with fracture, groups 1 and 2, respectively) and 285 females with natural menopause in mean age of 56.4+/-7.0y (176 without and 109 with fracture, groups 3 and 4, respectively) were studied. Mean age, age of menopause, years since menopause (YSM), duration of fertile period (durFER) and body size did not differ between women after surgical and natural menopause and between non-fractured and fractured groups. No additional factors known to influence bone metabolism (either diseases or medications) or osteoporosis treatment were noted in the subjects studied. Skeletal status was evaluated by quantitative ultrasound (QUS) of the calcaneum using the Achilles system (Lunar, USA). RESULTS Calcaneal QUS results were significantly higher: in women after natural than surgical menopause (p<0.05), in non-fractured females after natural menopause than in non-fractured females after surgical menopause (p<0.001) and in women after natural menopause without fracture compared with those with fracture (p<0.000001). The same comparisons between fractured groups and between women after surgical menopause with and without fracture revealed no significant differences. QUS parameters were regressed in a stepwise, multiple regression analysis on age, YSM, durFER, weight and height for all groups. In group 1, YSM had a negative influence and durFER was a protective factor; in group 2, age and durFER were a negative factors and YSM had no influence; in group 3, age and YSM were a negative factors (no role of durFER) and in group 4, only YSM had a negative influence, and durFER was a protective factor. CONCLUSION Surgical menopause seems to be a risk factor for osteoporotic fracture because of low ultrasound values.

Abstract
CONTEXT We reported previously that Old Order Amish (OOA) women have fewer hip fractures and higher bone mineral density (BMD) than non-Amish Caucasian women. OBJECTIVE The objective of this study was to determine whether the high parity characteristic of OOA women contributes to their relative bone health. Previous data on the long-term effects of parity on BMD have yielded conflicting results with few data from very high parity populations. This observational study included participants in the Amish Family Osteoporosis Study, begun in 1997 to identify genetic and clinical determinants of osteoporosis in the OOA. We measured BMD by dual-energy x-ray absorptiometry at the spine, hip, and distal radius in 424 parous OOA women aged 40 and older (mean age, 57.7 +/- 12 yr; mean parity, 7.6 +/- 2.9). RESULTS Increasing parity was associated with later menopause (P = 0.001) and modestly, but not significantly, higher body mass index (BMI) (P = 0.09). Increasing parity was associated with higher BMD at the total hip and trochanter (age-adjusted P = 0.02 and 0.03), no longer statistically significant after accounting for BMI. Among women aged 50-59 yr, parity was strongly associated with BMD even after accounting for age and BMI (age-adjusted P = 0.02), although this was not true for women younger than 50 or at least 60 yr old. CONCLUSIONS We conclude that high parity is associated with increased hip BMD in OOA women, largely mediated by higher BMI. The parity-hip BMD association remained statistically significant after accounting for age and BMI only in women aged 50-59 yr, partially explained by a later menopausal age with high parity. The benefit of high parity on BMD appeared to be lost soon after the menopausal transition, and, therefore, these data provide evidence of neither a detrimental nor beneficial effect of high parity on long-term bone health.

Abstract
UNLABELLED The role of growth hormone (GH) for maintaining normal erythropoiesis among non-GH-deficient elderly subjects is not known. OBJECTIVES To determine relationships between the concentrations of serum insulin-like growth factor-1 (IGF-1) and it's carrier protein insulin-like growth factor binding protein 3 (IGFBP-3), as well as plasma erythropoietin (EPO), and blood haemoglobin (Hb) in elderly subjects. METHODS Serum IGF-1 and IGFBP-3 and plasma EPO were, in addition to basal haematological tests, measured in a community based representative population sample of 70-yr-olds (n = 619; 317 women and 302 men). Statistical analyses were made before and after exclusion of non-healthy subjects. RESULTS Mean IGF-1 concentration was higher among men than women (155 vs. 138 mug/L, P = 0.0000), and that of IGFBP3 lower (2.21 vs. 2.65 mg/L, P = 0.0000). Exclusion of subjects with demonstrable disorders did not significantly influence the distributions of serum-IGF-1 and serum-BP-3. Hb concentration was positively correlated to concentrations of IGF-1 (r = 0.15, P < 0.01 for the men; r = 0.34, P < 0.001 for the women), and IGFBP-3 (r = 0.07, n.s. for the men; r = 0.27, P < 0.001 for the women), and negatively correlated to EPO concentration (r = -0.34, P < 0.001 for the men; r = -0.42, P < 0.001 for the women). In multivariate analysis, serum concentrations of IGF-1, iron, and plasma concentrations of EPO were independently correlated to Hb among both men and women. CONCLUSION GH and/or IGF-1 are, independently from EPO and regardless of health status and sex, a significant determinant of Hb in elderly subjects.

Abstract
During pregnancy and lactation, changes occur in a variety of factors which have great potential to influence bone mineral density (BMD). Smoking habits, the level of alcohol consumption, the level of physical activity, body weight, soft tissue composition and hormone levels are all factors that change during the course of these conditions. Some of these factors are capable of increasing BMD, and some can reduce it. Due to these various changes, it is virtually impossible to predict the development in BMD that will occur during a pregnancy and lactation. However, longitudinal studies have suggested that both pregnancy and lactation are associated with a BMD loss of up to 5%, albeit that the BMD recovers after weaning. Cross-sectional studies have indicated that women with many children and a long total period of lactation have similar or higher BMD and similar or lower fracture risk than their peers who have not given birth. As the studies showing this trend have been observational and cross sectional case-control studies, the conclusions can only be regarded as being suggestive, and no causality can be proven.

Abstract
In a prospective cohort of 7,598 women aged 75 and over, we analyzed the effect of age on the ability of femoral neck bone mineral density (BMD) and of ultrasound (BUA and SOS) of the calcaneus to predict hip fracture. Unadjusted regression analysis showed that the risk of hip fracture was increased 1.7 times for one standard deviation increase in age (3.7 years). Overall, for a decrease of one standard deviation in quantitative bone measures, the risk was significantly increased by 2.2 times for BMD (1.9-2.5), 1.8 for BUA (1.6-2.1), and 1.9 for SOS (1.6-2.2). However the average relative risk associated with a decrease in BMD tends to diminish with advancing age, meaning that a smaller part of the risk is explained by BMD in the very elderly. This is confirmed by the areas under the ROC curves (AUC) of BMD that are significantly better before 80 years (0.75 [0.73-0.76]) than after (0.65 [0.63-0.67] in group 80-84 years and 0.65 [0.61-0.68] in group >/=85). On the other hand, as the absolute risk increases exponentially with age, the number of hip fractures attributable to a low BMD is still important in the very elderly, the risk difference between the lowest and the highest quartile of BMD is 25 hip fractures / 1,000 woman-years in the group >/=85 compared with 16 in the two other groups. Thus, after 80, quantitative assessment of bone may still be of interest for clinical decisions. Compared with quantitative ultrasound parameters, the ability of BMD to predict hip fracture was significantly superior to that of BUA and SOS only before the age of 80 (AUC of BMD 0.75 [0.73-0.76], BUA 0.67 [0.66-0.69], SOS 0.67 [0.65-0.69]). For patients older than 80, we did not observe significant differences in AUC between DXA and QUS to predict hip fracture.

Abstract
OBJECTIVE The relation of hysterectomy and oophorectomy to change in bone mineral density (BMD) was examined in older women using and not using estrogen replacement therapy (ERT). METHODS Women aged 60-80 years from the Rancho Bernardo Study attended clinic visits in 1988-1991 and 1992-1995 when hysterectomy and oophorectomy were ascertained, ERT use was validated and spine and hip BMD was assessed at both visits with DEXA. Women were either current ERT users or nonusers at both visits. RESULTS Among these 447 women, average age was 71 (S.D.=9.0); average years postmenopause was 24.7 (S.D.=10.9). Overall, 122 had a hysterectomy with ovarian conservation and 91 had a hysterectomy with bilateral oophorectomy; 41% reported current ERT use for an average duration of 19.1 years (S.D.=10.8). Hysterectomized women were 2.3 times more likely to report ERT use than intact women (P<0.001). Comparisons adjusted for age, obesity, and age at menopause but not for ERT use showed hysterectomized women had less bone loss per year at the hip than intact women (P<0.05). However, this difference was explained by ERT; after adjustment for ERT, mean hip bone loss per year was -0.57% for intact women, -0.42% for hysterectomized women with ovarian conservation and -0.32% for bilaterally oophorectomized women (P's>0.10). There were no differences by hysterectomy or oophorectomy in bone loss at the spine or femoral neck. For all sites, women using ERT had higher BMD at both visits than nonusers (P's<0.001). Stratification by ERT showed that within users and nonusers, there were no differences in BMD or bone loss at any site by hysterectomy or oophorectomy. CONCLUSIONS There are no long term effects of hysterectomy and bilateral oophorectomy on bone loss. Women who use ERT have better BMD than nonusers.

Abstract
BACKGROUND Pregnancy is a time of increased need for calcium. The role of calcium supplements in altering maternal responses to fetal demand for calcium is not fully understood. This article describes the results of a randomized, crossover trial of calcium supplementation on bone resorption among pregnant women. DESIGN/SETTING PARTICIPANTS: Thirty-one Mexican women at 25-35 weeks gestation participated in the study for 20 days. Each woman received a 1200 mg calcium supplement on 10 consecutive days and a multivitamin without calcium for 10 days. Urine samples were collected daily. Two pooled specimens from each subject (representing urine from multivitamin days and from calcium days) were preserved, and levels of cross-linked, N-telopeptides of type I collagen (NTX), a biomarker of bone resorption, were measured. Dietary calcium intake was assessed using a food-frequency questionnaire. RESULTS Of the 31 participants, 27 (87.1%) showed reductions in urinary NTX levels while ingesting calcium supplements. When not ingesting calcium, NTX levels for the 31 subjects had a mean of 96.8 nM BCE/mM creatinine; this was significantly higher (p<0.001) than the mean urinary NTX levels of 83.2 nM BCE/mM creatinine during ingestion of the calcium supplements. Neither age nor dietary calcium intake was a significant predictor of treatment effect. CONCLUSION A bedtime, 1200-mg calcium supplement during the third trimester of pregnancy reduces maternal bone resorption by an average of 13.6 nM BCE/mM creatinine (14%), as reflected by urinary NTX levels. These results suggest that calcium supplements reduce maternal skeletal-bone turnover during the third trimester of pregnancy.

Abstract
After menopause, especially after bilateral oophorectomy, androgens are significantly reduced in blood and this would influence the well-being of the woman. A Female Androgen Deficiency Syndrome has been described and it is logical to add androgens to the classical oestrogen replacement therapy. There are several advantages of such combined treatment including higher bone density, better sexual function, improved mood and general sense of well-being, less depression and enhanced cognitive functioning. Side effects upon lipids are minimal and without any long-term effect on cardiovascular morbidity as long as low dosage is used. It seems that low dose of androgen therapy is a very interesting treatment option for menopausal women but further studies are needed before clinical use is recommended.

Abstract
To determine the magnitude and mediators of the association between cigarette smoking and bone mass in the epidemiologic literature we reviewed articles, published abstracts, and conference proceedings, identified through MEDLINE, psychological abstracts, conference proceedings, and article bibliographies. We studied cross-sectional and prospective human studies that provided a quantitative measure of bone mass (X-ray, absorptiometry, or computed tomography) as a function of cigarette smoking exposure. Effects were expressed as pooled standardized mean differences for categorical comparisons (e.g., bone mass in current versus nonsmokers), and as pooled correlation coefficients for continuous comparisons (e.g., correlation of bone mass and pack-years of smoking). Effects were derived for combined bone sites (all bone sites pooled within each study) and four specific sites (hip, lumbar spine, forearm, and os calcis), and were examined overall and as a function of subject and methodologic characteristics (gender, age, body weight, menopausal status, health status). Data were pooled across 86 studies, enrolling 40,753 subjects. Smokers had significantly reduced bone mass compared with nonsmokers (never and former smokers) at all bone sites, averaging a one-tenth standard deviation (SD) deficit for combined sites. Deficits were especially pronounced at the hip, where the bone mass of current smokers was one-third of a SD less than that of never smokers. Overall, effects were greatest in men and in the elderly, and were dose-dependent. In prospective studies, smokers had greater rates of bone loss over time compared with nonsmokers. Bone mass differences remained significant after controlling for age and body weight differences between the two groups. Absolute effect sizes at most bone sites were greatest for current smokers compared with never smokers, intermediate for current smokers compared with former smokers, and lowest for former smokers compared with never smokers, suggesting that smoking cessation may have a positive influence on bone mass. Based on these data, it is estimated that smoking increases the lifetime risk of developing a vertebral fracture by 13% in women and 32% in men. At the hip, smoking is estimated to increase lifetime fracture risk by 31% in women and 40% in men. It appears that smoking has an independent, dose-dependent effect on bone loss, which increases fracture risk, and may be partially reversed by smoking cessation. Given the public health implications of smoking on bone health, it is important that this information be incorporated into smoking prevention and cessation efforts.

Abstract
OBJECTIVES We sought to examine the relationship between reproductive history and measures of selected gonadotrophins and steroid hormones among post-menopausal women. Previous studies have suggested that there is a negative correlation between parity and post-menopausal serum estrogens, which may be a mechanism by which pregnancies protect women from the development of breast cancer. METHODS We analyzed women who experienced a natural menopause within the Healthy Women Study cohort both 1 and 8 years after menopause. Lifetime reproductive history was obtained and blood was assayed for estrone, estradiol, androstenedione, testosterone, follicle stimulating hormone (FSH), and luteinizing hormone (LH) at 1 year post-menopause and for many of these steroid hormones at 8 years post-menopause. Also at 8 years post-menopause, a hip bone mineral density measure was obtained. RESULTS Age at menopause related to a modest increase in estrone at 1 year but a decrease in estrone and estradiol at eight years. Adjustment for body mass index (BMI), oral contraceptive use, alcohol use, cigarette smoking, and education had little impact on these findings. There were no other internally consistent relationships between reproductive variables and steroid hormones or hip-bone mineral density. CONCLUSIONS These observations do not support the hypothesis that parity acts to diminish endogenous levels of post-menopausal estrogens.

Abstract
Osteoporosis is a common problem, affecting >28 million Americans, >/=75% of whom are postmenopausal women. In 1995 the cost of caring for patients with complications of osteoporosis was $14 billion. Of the 1.5 million osteoporotic fractures that occur in this country each year, the most serious are hip fractures. It is estimated that approximately 10% to 20% of women die within a year after a hip fracture. Numerous studies reveal that although osteoporotic fractures are preventable most women are not receiving or choosing to receive the medical care that they need to prevent them. Great strides have been made in establishing the importance of ovarian hormones in not only the pathophysiology but also the treatment of postmenopausal osteoporosis. Clinical studies show that estrogen and estrogen-androgen replacement therapies both prevent the development of osteoporosis, as determined by bone mineral density determinations and bone marker analyses. The addition of an androgen to hormone replacement therapy may prevent bone loss and stimulate bone formation.

Abstract
A cross-sectional study was undertaken in 58 consecutive women with premenopausal hysterectomy and ovarian conservation (Group 1) and 59 randomly selected women with natural menopause (Group 2) to determine the effect of hysterectomy on bone mineral density (BMD). Subjects were similar in age, height, weight, body mass index (BMI), exercise levels, family history of osteoporosis and smoking levels, but not years since hysterectomy or menopause (Group 1 = 14.9 +/- 10.8 years versus Group 2 = 9.8 +/- 8.7 years; p = 0.005), age at hysterectomy or menopause (Group 1 = 42.3 +/- 7.3 years versus Group 2 = 45.9 +/- 6.9 years; p = 0.008) or current alcohol consumption (Group 1 = 13.8% versus Group 2 = 39%; p = 0.002). Dual X-ray absorptiometry of the raw (unadjusted) lumbar spine and femoral neck BMD were similar for the 2 groups: lumbar spine = 0.947 +/- 0.179 g/cm2 (Group 1) versus 0.958 +/- 0.203 g/cm2 (Group 2) (p = 0.76) and femoral neck = 0.825 +/- 0.127 g/cm2 (Group 1) versus 0.815 +/- 0.146 g/cm2 (Group 2) (p = 0.71). Multivariate linear regression revealed that factors other than hysterectomy were associated with lumbar spine and femoral neck BMD. Thus, prior hysterectomy with ovarian conservation has no adverse effect on lumbar spine or femoral neck BMD.

Abstract
To assess fracture risk following bilateral oophorectomy, we conducted a population-based retrospective cohort study among the 463 Rochester, Minnesota women who underwent bilateral oophorectomy for benign ovarian conditions in 1950-1979. During 7220 person-years of observation, there appeared to be a modest increase in the risk of distal forearm fractures (standardized morbidity ratio [SMR] 1.4; 95% CI 1.0-2.0) and vertebral fractures (SMR 1.9; 95% CI 1.3-2.8) but not hip fractures (SMR] 1.1; 95% CI 0.6-1.9). Although our statistical power was quite limited, there was a suggestion that women who became estrogen deficient at a young age were at greater risk of fracture. However, the youngest women were more likely to be on estrogen replacement therapy, and for longer durations, so that the average age at the onset of estrogen deficiency in this population was 47 years.

Abstract
OBJECTIVE The aim of the study was to study the influence of urinary disorders as urinary incontinence on the prevalence of hip fracture in 85-year-old women. METHODS A representative community-based population study was performed at the geriatric outpatient department of a university hospital in a sample consisting of 658 85-year-old women, of which 69% were living at home and 31% were living were living in institutions. The prevalence of hip fractures was registered and measurement with dual photon absorptiometry of the right calcaneum was performed. The subjects were questioned covering sociodemographic background, the occurrence, type, frequency and amount of urinary incontinence, medical examinations and investigations of the prevalence of hip fracture. RESULTS Hip fracture was significantly associated with urinary incontinence (P < 0.001) for women and the odds ratio of hip fracture was twice that found in general population (OR = 2.42). Body mass index and weight were both significant higher (P < 0.01) among women with urinary incontinence and hip fracture. The frequency of urinary incontinence was also significant correlated to hip fracture (P < 0.001). Subjects with diabetes had a tendency to be associated with urinary incontinence (P < 0.06). In a logistic multiple regression analysis, body mass index, urinary incontinence and cancers were the only explanatory factors for hip fractures at 85 years of age. CONCLUSION The association between postmenopausal urinary incontinence and hip fractures are multifactorial and whether this is a result of decreasing estrogen levels or a result of general aging process is still under debate. Women with urinary incontinence and earlier atrumatic multiple postmenopausal fractures should be considered a special target group for estrogen prophylaxis in order to prevent further severe fractures.

Abstract
OBJECTIVES The purpose of this study was to investigate whether a previous fracture is a risk factor for fracture later in life and its association with tobacco smoking, menopausal age and the use of oral contraceptives. This is an epidemiological population study based on a questionnaire. A sample of 10000 women from seven birth cohorts between 1900-1940 was obtained at random from the population register. The overall response rate was 74.6%. The responders (n = 7459) represented 53% of the total population. METHODS The women from all these birth cohorts were questioned regarding a possible history of fractures and the year in which they were sustained. The questionnaire also included questions about menopausal age, use of oral contraceptives, previous gynaecological operations and possible oestrogen medication. The women from the 1900-1920 birth cohorts were questioned in detail about urogenital disorders, while tobacco smoking data were recorded only for the 1930 and 1940 birth cohorts. RESULTS The relative risk of sustaining a further fracture was significantly related to fracture premenopausally before 40 years of age and later fracture postmenopausally after 60 years of age (1.29; 0.97-1.70) compared to controls (0.78; 0.59-1.03)(P = 0.03). Both an early menopause and tobacco smoking were associated significantly with repeated fractures, while use of oral contraceptives had a protective effect against repeated fractures in the 1940 birth cohort. Logistic multiple regression showed that a fracture was a significant independent risk factor for further fracture in both cohorts 1900-1920 (P < 0.01) and 1930-1940 (P < 0.05). CONCLUSIONS This study suggests poorer protective resources against new fractures among women with previous fractures, and that lack of oestrogen menopausally can partly explain the enhanced risk of fracture, not only during the menopause but also later in life when a hip fracture may have immense consequences. The results should draw our attention to emphasise the need for active treatment of patients with established osteoporosis because of the increased risk of new fractures later in life.

Abstract
OBJECTIVE The association between urinary disorders, such as ongoing urinary incontinence (UI), history of urinary incontinence (HIST-UI) and urinary tract infections (UTI), and fractures in peri- and postmenopausal women was assessed in an epidemiological study. SUBJECTS AND METHODS The sample consisted of 10000 women from seven birth cohorts, born between 1900 and 1940, who were investigated regarding urinary disorders, fractures and reproductive history by means of a postal questionnaire. RESULTS The overall response rate was 74.6%. The respondents (n = 7459) represented 53% of the total population from the respective birth cohorts. There was a significant independent correlation between UI, HIST-UI and UTI, respectively, and fractures after the age of 30. In subjects with HIST-UI, tobacco smokers compared to non-smokers had significant more fractures in both the 1930 and 1940 birth cohorts (P < 0.01). Logistic multiple regression in the 1930 and 1940 cohorts demonstrated that age (P < 0.001), HIST-UI (P < 0.001) and tobacco smoking (P < 0.05), respectively, had an independent explanatory value for fractures. CONCLUSION The prevalence of fractures increased with increasing age, in smokers compared to non-smokers and in women with a history of UI.

Abstract
In a retrospective analysis of 49 patients who received bone graft augmentation to the maxillary sinuses in conjunction with implant insertion, 11 patients had a significantly reduced success rate. The aim of the present study was to determine whether bone quality, as assessed by osteometry and selected haematologic and urinary tests, influences the integration of implants, and whether such data can be prognostically useful. Relative bone mass density (BMD%) differed significantly among these patients as compared to age- and sex-matched control patients receiving the same reconstructive treatment (P=0.01). Other parameters tested did not demonstrate any significant differences. In addition to local complications, general disorders, such as osteoporosis, must be considered in cases of excessive implant loss.

Abstract
The aims of this study were to determine common international risk factors for hip fracture in women aged 50 years or more. We studied women aged 50 years or more who sustained a hip fracture in 14 centers from Portugal, Spain, France, Italy, Greece, and Turkey over a 1-year period. Women aged 50 years or more selected from the neighborhood or population registers served as controls. Cases and controls were interviewed using a structured questionnaire on work, physical activity, exposure to sunlight, reproductive, history and gynecologic status, height, weight, mental score, and consumption of tobacco, alcohol, calcium, coffee, and tea. Significant risk factors identified by univariate analysis included low body mass index (BMI), short fertile period, low physical activity. lack of sunlight exposure, low milk consumption, no consumption of tea, and a poor mental score. No significant adverse effects of coffee or smoking were observed. Moderate intake of spirits was a protective factor in young adulthood, but otherwise no significant effect of alcohol intake was observed. For some risks, a threshold effect was observed. A low BMI and milk consumption were significant risks only in the lowest 50% and 10% of the population, respectively. A late menarche, poor mental score, low BMI and physical activity, low exposure to sunlight, and a low consumption of calcium and tea remained independent risk factors after multivariate analysis, accounting for 70% of hip fractures. Excluding mental score and age at menarche (not potentially reversible), the attributable risk was 56%. Thus, about half of the hip fractures could be explained on the basis of the potentially reversible risk factors sought. In contrast, the use of risk factors to "predict" hip fractures had moderate sensitivity and specificity. We conclude that variations in lifestyle factors are associated with significant differences in the risk of hip fracture, account for a large component of the total risk, and may be of some value in selecting individuals at high risk.

Abstract
Recently, it has been suggested that lateral (LAT) spine bone mass measurements by absorptiometry may be more sensitive for detecting bone loss than the standard anteroposterior (AP) projection. The aim of this study was to evaluate the precision of LAT spine dual-energy X-ray absorptiometry (DEXA) and its diagnostic sensitivity. A group of 1554 subjects with no risk factors that might affect bone metabolism and 185 osteoporotic patients with vertebral fractures were studied. Bone mineral density (BMD) was measured in the lumbar spine (standard AP and LAT projections) and proximal femur with a DEXA absorptiometer. The precision of the measurements was assessed in 15 volunteers. Diagnostic sensitivity was evaluated by the Z-score method. Comparing young people and the elderly, spine bone loss in the latter was similar for AP and LAT projections, when it was evaluated in absolute values (glcm2). However, when it was evaluated in percentage terms, bone loss was about twice as high in the LAT projection. LAT spine BMD correlated significantly with all the other areas assessed. The best correlation was found with the standard AP projection (r = 0.67, P < 0.0001). The precision in the LAT projection was found to be within an acceptable range (1.6% in normal subjects, 2% in osteoporotic patients), even though it was about twice that obtained in the AP projection. Diagnostic sensitivity was also better with the AP projection. It is concluded that LAT spine BMD measurements can be assessed with acceptable precision although it is about twice as high as for AP spine measurements.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
OBJECTIVE Our purpose was to investigate the influence of premenopausal hysterectomy on bone mass. STUDY DESIGN A cross-sectional study was performed on 69 women who had premenopausal hysterectomy and 427 women with natural menopause 50 to 59 years old. Bone mineral density was measured in the distal forearm by single-energy x-ray absorptiometry. Body composition and bone mineral density in the anteroposterior spine, proximal femur, and total body was measured by dual-energy x-ray absorptiometry. Bone turnover was determined by plasma osteocalcin, serum alkaline phosphatase, and fasting urinary calcium corrected for creatinine excretion. RESULTS Women who had undergone premenopausal hysterectomy had similar bone mineral densities compared with women with an intact uterus in all compartments, apart from a 6% to 11% higher bone mineral density (p < 0.05 to 0.001) in the proximal femur. The women who had undergone premenopausal hysterectomy had 2% to 11% more fat (significant for arm fat, p < 0.05), 9% to 13% lower serum follicle-stimulating hormone levels (p < 0.01), 10% to 13% higher serum estradiol levels (not significant), and 8% to 9% lower osteocalcin levels (p < 0.05 to 0.07). This bone mineral density difference could thus be explained by extragonadal sex hormone production. CONCLUSION Premenopausal hysterectomy did not reduce ovarian function and increase bone turnover and bone loss.

Abstract
The relationship between gynecological history and bone mineral density (BMD) of the lumbar spine and femoral neck was studied in 3126 perimenopausal women. The study population was a random, stratified sample of participants, selected from the Kuopio Osteoporosis Study, which consisted primarily of all 14,220 women aged 47-56 years in Kuopio Province in 1989. After exclusion of 1521 women reporting past or present hormonal replacement therapy (HRT), 1605 women formed the final study population. Present HRT users had significantly higher lumbar BMD but not femoral BMD, than non-hormone users. Postmenopausal status, late menarche, and bilateral oophorectomy were risk factors for low BMD. Protective factors against low BMD were increased body weight, increased number of pregnancies, as well as hysterectomy without bilateral oophorectomy. The majority (43.8%) of these operations had been performed due to the presence of leiomyomas. No significant correlation was found between nulliparity, breast-feeding or amenorrhea before the age of 30 and BMD. In the multiple regression analysis, gynecological variables could account for only 18.4-26.8% of the variance in BMD, while time since last periods, age, age at menarche, weight and hysterectomy were the most significant variables. We conclude that reproductive history gives rise to some special risk groups, to whom BMD measurements and osteoporosis prevention efforts should be directed. However, it is impossible to predict BMD by gynecological characteristics.

Abstract
To determine the ability of bone density to predict fractures in very elderly women, we examined the association of bone density with non-spine, hip, wrist and humerus fractures in 8699 Caucasian women aged 65-79 years and 1005 women aged 80 years and older who were participants in the prospective Study of Osteoporotic Fractures. Follow-up averaged 4.9 (+/- 1.0) years after baseline measurement of appendicular bone density (single-photon absorptiometry; Osteon-Osteo Analyzer) and 2.9 (+/- 0.6) years after measurement of hip and anteroposterior lumbar spine bone density (dual-energy X-ray absorptiometry; Hologic QDR 1000) at a later examination. In general, measurements of bone density in the oldest women retained their predictive value for fractures. Among women aged 80 and over a 1 standard deviation decrease in bone density of the distal radius was associated with an increased risk of non-spine (relative risk: 1.6; 95% confidence interval: 1.3, 1.8), wrist (1.7; 1.2, 2.4) and humerus fracture (2.9; 1.8, 4.7), while a 1 standard deviation decrease in femoral neck bone density was associated with an increased risk of non-spine (1.9; 1.6, 2.4), humerus (2.4; 1.2, 4.7) and hip fracture (2.1; 1.4; 3.2). However, only trochanteric but not femoral neck fractures were associated with low bone density in these oldest women. The excess risk of fracture in women with below-median bone density was greater in those aged 80 years and over compared with the younger women: 38.4 v 20.4 per 1000 woman-years for non-spine fracture and 12.2 v 3.2 per 1000 woman-years for hip fracture.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A large number of cross-sectional studies suggest that rates of bone loss decrease in the elderly, particularly at the spine and radius. For this reason it has been argued that bone mass measurements are unhelpful in assessing fracture risk in the elderly and that drugs affecting bone metabolism are less likely to be of benefit in reducing this risk. This paper reviews the assumptions on which these conclusions are based and argues that in many instances they are flawed. Indeed, studies examining rates of bone loss in the elderly either directly or by biochemical indices of bone turnover suggest that bone loss continues throughout life and may even accelerate after the age of 70 years. This conclusion supports the view that identification of patients at risk and subsequent treatment is of value in all age groups.
