Different health behaviours and clinical factors associated with bone mineral density and bone turnover in premenopausal women with and without type 1 diabetes.

BACKGROUND: Women with type 1 diabetes (T1DM) have an elevated fracture risk. We therefore compared the associations of health behaviours and clinical factors with bone mineral density (BMD) and bone remodelling between premenopausal women with and without T1DM to inform potential interventions. METHODS: Participants included women with T1DM (n = 89) from the Wisconsin Diabetes Registry Study and age-matched and race-matched controls without diabetes (n = 76). Peripheral (heel and forearm) and central (hip and spine) BMD, markers of bone resorption and formation, bone cell signalling, glycaemic control, and kidney function were assessed. Health behaviours and medical history were self-reported. RESULTS: In controls, but not in women with T1DM, older age was associated with lower bone resorption (p ≤ 0.006) and formation (p = 0.0007). Body mass index was positively associated with heel and forearm BMD in both controls and T1DM women (all p < 0.0001), but with hip and spine BMD only in controls (p ≤ 0.005). Worse glycaemic control during the previous 10 years, greater alcohol intake, history of smoking, and lack of physical activity were associated with poorer bone outcomes only in women with T1DM (all p ≤ 0.002), whereas use of hormonal contraceptives was related to low bone formation in both women with and without T1DM (all p ≤ 0.006). Diabetes duration, insulin dose, residual C-peptide, and kidney function were not associated with bone in T1DM. CONCLUSIONS: Age and body mass index may not predict bone health in T1DM women. However, modifiable behaviours such as optimizing glycaemic control, limiting substance and hormonal contraceptive use, and increasing physical activity may improve bone health in T1DM women.

Oxytocin levels are lower in premenopausal women with type 1 diabetes mellitus compared with matched controls.

BACKGROUND: Oxytocin, a hormone most commonly associated with parturition and lactation, may have additional roles in diabetes complications. We determined oxytocin levels in premenopausal women with type 1 diabetes mellitus (T1DM) compared with non-diabetic controls and examined associations of oxytocin with health behaviours, clinical factors, biomarkers, kidney function and bone health. Lower oxytocin was hypothesized for T1DM. METHODS: A cross-sectional study of premenopausal women with T1DM (n = 88) from the Wisconsin Diabetes Registry Study, a population-based cohort of incident T1DM cases, and matched non-diabetic controls (n = 74) was conducted. RESULTS: Women with T1DM had lower oxytocin levels than controls adjusting for caffeine and alcohol use (p = 0.03). Health behaviours associated with oxytocin differed between women with and without T1DM: oxytocin was negatively associated with hormonal contraceptive use (quantified as lifetime contraceptive oestrogen exposure) in women with T1DM (p = 0.003), whereas positively related to hormonal contraceptive use (quantified as never/former/current) in controls (p < 0.001). Oxytocin had a positive association with adiposity (waist-to-hip ratio and leptin) in women with T1DM and a negative relationship with adiposity (weight gain) in controls. In T1DM only, oxytocin was positively associated with caffeine intake (p = 0.01) and negatively associated with alcohol use (p = 0.01). Oxytocin was not related to glycemic control, kidney function or bone health in T1DM. CONCLUSIONS: Oxytocin levels are lower in women with T1DM than matched controls. Oxytocin also has opposing associations with hormonal contraceptives and adiposity in women with and without T1DM. Research is needed to determine if the altered oxytocin milieu in T1DM is associated with oxytocinher health outcomes.

Bone health evaluation in a veteran population: a need for the Fracture Risk Assessment Tool (FRAX).

BACKGROUND: Approximately 2 million men in the United States have osteoporosis, but men are seldom evaluated or treated to prevent fracture. In the expanding veteran population, the fracture risk assessment tool, FRAX, could help reduce fracture risk. However, it is unknown how many veterans would meet the FRAX treatment threshold. OBJECTIVE: To determine the proportion of untreated veterans who should be considered for osteoporosis treatment according to the Fracture Risk Assessment Tool (FRAX) among a randomly selected sample of older veterans receiving care at one Veterans Hospital and to determine the proportion of veterans in the sample who had received treatment. METHODS: A retrospective review of 150 randomly selected charts from male veterans at least 70 years of age and female veterans at least 65 years of age receiving primary care at the William S. Middleton Memorial Veterans Hospital, Madison, WI, between January 1, 2007, and October 1, 2010. This study focused on men, but women were included per institutional review board policy. RESULTS: Charts from 147 men and 3 women were reviewed; 25 men had received osteoporosis treatment. Of 122 untreated men, 74 (61%) met FRAX treatment criteria, including 14 who had fractured. Although bone density testing is recommended by the National Osteoporosis Foundation for men at least 70 years old, only 21 (17%) untreated men had been tested. CONCLUSIONS: Most veterans who met FRAX criteria were not treated, including some who had had fractures. The VA should consider recommending FRAX to identify veterans at high risk for fracture.

Characteristics associated with bone mineral density responses to alendronate in men.

Some patients experience reduced bone mineral density (BMD) despite bisphosphonate therapy. We performed a retrospective chart review study to detect factors associated with decreased BMD in men prescribed alendronate. Two investigators reviewed eligible medical records and used a standardized form to record potential characteristics predicting men's response to alendronate. We analyzed patient characteristics associated with annualized change in hip and spine BMD (D-BMD). Among 115 eligible men, 19 (17 %) experienced significantly decreased BMD at the hip or spine, defined as a change exceeding precision error. Eleven men (10 %) fractured during therapy. Spine D-BMD was positively associated with adherence to alendronate (R = 0.23, p = 0.02) and inversely associated with baseline body weight (R = -0.21, p = 0.03). Hip D-BMD was positively associated with annualized weight change (R = 0.19, p = 0.0498) and negatively associated with patient age and number of concomitant medications (R = -0.21, p = 0.03; R = -0.20, p = 0.03, respectively). In stepwise linear models, spine D-BMD was associated positively with alendronate adherence and multivitamin use and negatively with baseline body weight. Hip D-BMD was negatively associated with age. Fracture during treatment was associated with fracture prior to therapy (p = 0.03). In this small study of men prescribed alendronate, BMD response showed a positive association with adherence to therapy, weight gain, and use of a multivitamin. By contrast, older age, higher baseline body weight, and higher number of medications were each associated with a decrease in BMD. Larger studies are needed to confirm and extend these findings.

Patient assessment in the diagnosis, prevention, and treatment of osteoporosis.

Assessment of the patient with osteoporosis includes history and physical examination, laboratory testing, and imaging studies. Information gathered during this assessment assists clinicians in targeting strategies to prevent fractures. The medical history should contain items such as personal and family history of fractures, lifestyle, intake of substances such as vitamin D, calcium, corticosteroids, and other medications. The physical examination can reveal relevant information such as height loss and risk of falls. Bone mineral density (BMD), most commonly determined by dual-energy x-ray absorptiometry, best predicts fracture risk in patients without previous fracture. BMD testing is most efficient in women over 65 years old but is also helpful for men and women with risk factors. Serial BMD tests can identify individuals losing bone mass, but clinicians should be aware of what constitutes a significant change. Laboratory testing can detect other risk factors and can provide clues to etiology. Selection of laboratory tests should be individualized, as there is no consensus regarding which tests are optimal. Biochemical markers of bone turnover have a potential role in fracture risk assessment and in gauging response to therapy, but are not widely used at present. Clinicians should be aware of problems with vitamin D measurement, including seasonal variation, variability among laboratories, and the desirable therapeutic range. Careful assessment of the osteoporotic patient is essential in developing a comprehensive plan that reduces fracture risk and improves quality of life.

Androgen deprivation in veterans with prostate cancer: implications for skeletal health.

BACKGROUND: Common risk factors for osteoporosis in older men include smoking, heavy use of alcohol, propensity to falls, and use of bone-toxic medications such as prednisone. There is also increasing appreciation of the skeletal risk faced by men receiving androgen deprivation therapy (ADT) for prostate cancer. Measures to prevent bone loss in such patients are available. OBJECTIVE: To test the following hypotheses in a population of veterans receiving ADT for prostate cancer: (1) fracture risk factors in addition to androgen deprivation would be found in most patients, (2) bone mass measurements would be assessed in a minority of patients, and (3) a minority of the subjects would receive bisphosphonate therapy or have contraindications for such treatment. METHODS: We conducted a retrospective chart review of male veterans receiving ADT from 1993 through 2001, at the Veterans Affairs Medical Center, Madison, WI. RESULTS: One hundred and seventy-four subjects met study criteria, with a mean age of 76 years and median duration of 21 months of ADT. Eighty-one percent had risk factors in addition to ADT. Only 13% underwent bone density measurement by dual energy X-ray absorptiometry (DXA) and, of those measured, more than half had osteoporosis. Only 19% of the men received both calcium and vitamin D supplements. Antiresorptive therapy was provided to 11% of men, although more than two-thirds had no contraindications to therapy. A total of 24 men sustained a fracture after starting ADT. For men who did undergo bone density measurement, 77% received antiresorptive therapy. Of those who exhibited osteoporosis by DXA scan, 85% received antiresorptive therapy. CONCLUSIONS: Male veterans receiving ADT for prostate cancer received inadequate evaluation and treatment for osteoporosis. Based on our data, a simple and practical strategy to prompt further evaluation and improved care may be to undertake bone density measurements in men prior to or soon after commencing ADT.

Acceptability of pharmacy-based bone density measurement by women and primary healthcare providers.

OBJECTIVES: To assess women's information sources regarding, and monetary value placed on, pharmacy-based bone density screening. In addition, we evaluated clinicians' response to peripheral bone mass measurements. DESIGN: We recruited 197 women 50 years of age or older in four rural Midwestern community pharmacies. Each woman completed a questionnaire and underwent calcaneal bone density testing. Results were sent to participants' primary care providers. These providers, and others practicing within a 50-mile radius, were surveyed anonymously to evaluate usefulness of bone density data provided by this program or pharmacy-based osteoporosis screening in general. In addition, clinicians were asked how they would manage a woman with a calcaneal T-score of -1.3. RESULTS: Fifty-six percent of participants [95% CI, 49%-63%] became interested in screening through the media, and only 6% (CI, 3%-9%) became interested through contact with their primary care provider. Women were willing to pay a median of $25 for screening. Of 18 responding clinicians with patients in this study, 72% (CI, 47%-90%) found the results useful. Of the 67 responding clinicians, 51% (CI, 39%-63%) supported pharmacy-based bone mass measurement. For a case scenario of a woman with a calcaneal T-score of -1.3, 57% (CI, 46%-68%) of clinicians indicated that they would have ordered central dual-energy x-ray absorptiometry, and 20% (CI, 11%-29%) would have prescribed antiresorptive therapy. CONCLUSIONS: This study suggests that (1) women are an important force in obtaining bone density testing outside the clinic setting, both by self-education and willingness to pay, and (2) primary care clinicians receiving such results find them useful and indicate willingness to use them in decision-making.

Fracture risks for women in long-term care: high prevalence of calcaneal osteoporosis and hypovitaminosis D.

STUDY OBJECTIVES: To determine the prevalence of osteoporosis as assessed by peripheral bone mineral density (BMD) in women living in a nursing home, to determine how many women with low BMD had received a diagnosis of osteoporosis, to assess the prevalence of vitamin D deficiency, and to seek reasons for vitamin D deficiency. DESIGN: Measurement of calcaneal BMD and serum 25-hydroxyvitamin D. SETTING: Skilled nursing facility. PATIENTS: Forty-nine women aged 68-100 years. MEASUREMENTS AND MAIN RESULTS: Bilateral calcaneal BMD was measured by dual-energy x-ray absorptiometry and serum 25-hydroxyvitamin D by radioimmunoassay. Medical records were reviewed to assess osteoporosis risk factors, previous documentation of osteoporosis or malabsorption, and supplemental vitamin D intake. Fifty-nine percent of the 39 women with calcaneal BMD measurements (95% confidence interval [CI] 44-74%) exhibited calcaneal osteoporosis (T score < -2.5). Sixty percent (95% CI 46-74%) had 25-hydroxyvitamin D levels of 20 ng/ml or less, which is associated with secondary hyperparathyroidism; only 4% of women had levels above 30 ng/ml, recently recommended as optimal. Vitamin D status was suboptimal even in most women taking multivitamins. Osteoporosis was documented in the records of 17% of 23 women with calcaneal osteoporosis. CONCLUSION: Osteoporosis was prevalent but poorly documented in women living in the nursing home. Peripheral BMD measurements have the potential to improve the recognition and management of osteoporosis in women in long-term care facilities. The high prevalence of vitamin D deficiency, even in those taking multivitamins, indicates that practical new approaches for vitamin D repletion in this population are urgently needed.

Self-concept as a "BMT patient", illness intrusiveness, and engulfment in allogeneic bone marrow transplant recipients.

OBJECTIVE: The experience of cancer and its treatment by bone marrow transplantation (BMT) can enhance the salience of one's status as a patient in the evolution of self-concept. Illness and the patient role can come to dominate the sense of self, resulting in feelings of hopelessness, helplessness, and distress ("engulfment"). Illness-induced lifestyle disruptions ("illness intrusiveness") introduce adaptive demands, challenging preexisting conceptions of self. Illness intrusiveness and engulfment may interact, leading affected individuals to construe themselves as highly similar to a prototypical "BMT patient". METHODS: Ninety allogeneic BMT outpatients completed the Illness Intrusiveness Ratings Scale, Modified Engulfment Scale, and a semantic differential measure of self-concept as a BMT patient in an interview context. RESULTS: Illness intrusiveness correlated significantly with engulfment (r=.58, P<.0001) and with self-concept as a BMT patient (r=.27, P<.016). Engulfment did not correlate significantly with self-concept as a BMT patient (r=.15). Multiple regression analysis, controlling for relevant covariates, indicated a significant Illness Intrusiveness x Engulfment interaction effect on self-concept as a BMT patient [F(1,84)=4.93, P<.029]. CONCLUSIONS: Self-concept as a BMT patient increases as cancer and its treatment introduce increasing lifestyle disruptions (illness intrusiveness). These effects are amplified when self-experience is dominated by disease and treatment and patients feel helpless, hopeless, and distressed (engulfment).

Osteoporosis assessment strategies for male nursing home residents.

OBJECTIVES: Twenty-five to thirty percent of hip fractures occur in men, and nursing home residents have a 5-10-fold greater fracture risk than community-dwellers. Osteoporosis prevalence in men in long-term care, however, is poorly defined. Our objectives were to determine the prevalence of osteoporosis, as assessed by peripheral bone mineral density (BMD), in a group of institutionalized veterans, and to determine how many men with low BMD had received a prior diagnosis of osteoporosis. METHODS: Subjects were residents in a 740-bed skilled nursing facility (78% men). Male residents (n = 103) competent to give informed consent underwent bilateral calcaneal and forearm BMD by dual-energy X-ray absorptiometry (DXA). Prior osteoporosis documentation was sought in medical records. RESULTS: Twenty percent of veterans (95% confidence interval (CI) 12-28%) exhibited calcaneal osteoporosis (T-score < -2.5), and 62% (CI 52-72%) were osteoporotic at the forearm. Forearm and calcaneal BMD were correlated (r = 0.678, P < 0.001). BMD of the left and right forearm, and of left and right calcaneus, were highly correlated (r = 0.880, P < 0.001 and r = 0.931, P < 0.001, respectively). Documentation of osteoporosis existed for one of 20 men with calcaneal osteoporosis and four of 59 men with forearm osteoporosis. CONCLUSIONS: Osteoporosis was prevalent but poorly documented in institutionalized veterans. Discordance in T-scores between forearm and heel was similar to that reported in other studies. The broad range of T-scores among subjects suggests that peripheral BMD measurement may be useful for clinical fracture risk stratification. Correlation among skeletal sites indicates that measuring a single site may be practical.

Risk for osteoporosis in elderly nuns: need for better recognition and treatment.

BACKGROUND: The risk for osteoporosis in Catholic sisters (nuns) may be even higher than that of the general female population given their longer life expectancy (82.0 to 89.0 years vs 79.6 years for the average white woman) and the use of a traditional habit as a young adult, resulting in limited sun exposure (ie, exposure to vitamin D). OBJECTIVES: The aim of this study was to determine, in a group of elderly nuns attending an annual health screening day (Health Forum), how many met National Osteoporosis Foundation (NOF) treatment criteria using peripheral bone mineral density (BMD) measurements and risk factors; what proportion received adequate vitamin D; whether BMD was related to length of time that nuns wore a habit; and whether BMD measurement led to medical interventions. In addition, we compared the usefulness of calcaneal BMD with that of BMD at central sites for identification of those at risk for osteoporosis. METHODS: This cross-sectional study assessed BMD by calcaneal dual energy X-ray absorptiometry (DXA) and, for some participants, central DXA. A baseline questionnaire and follow-up mail survey also were included. RESULTS: Of the 230 nuns attending the Health Forum, 146 (63%) (mean age, 70 years; range, 48-90 years) participated in the study. Of these, 14% had calcaneal osteoporosis (T-score <-2.5) and 32% met NOF treatment criteria, indicating risk comparable to that of other postmenopausal American women. Sixty-four percent were receiving less than the recommended amount of vitamin D (≥400 IU/d for those aged <71 years and ≥600 IU/d for those aged ≥71 years). Calcaneal BMD was inversely related to the length of time nuns had worn a habit. Fifty-six women subsequently underwent central DXA. Using a calcaneal T-score of -1.2 to identify those with central osteoporosis, sensitivity and specificity of 78% and 76%, respectively, were obtained. According to the mail survey, 11 of 42 respondents who had met NOF treatment criteria started new medications for osteoporosis. CONCLUSIONS: Elderly nuns are at substantial risk for osteoporosis. Most receive inadequate vitamin D. For nuns and others who may have limited access to central DXA measurement, peripheral measurements may help identify those in need of further intervention. Further efforts, in addition to BMD measurements, are necessary to ensure appropriate therapy for those who meet treatment criteria.

Use of a questionnaire to assess vitamin D status in young adults.

OBJECTIVE: We hypothesized that young adults would commonly have vitamin D deficiency and that a questionnaire could help identify subjects with the condition. DESIGN: Between January and May 2004, we administered a questionnaire to a convenience sample of young adults. We measured each participant's serum level of 25-hydroxyvitamin D (25(OH)D) using a chemiluminescent assay and defined deficiency as serum 25(OH)D < 16 ng/ml. SETTING AND SUBJECTS: We recruited young adults living in Madison, Wisconsin without pre-existing conditions affecting vitamin D and/or Ca metabolism. RESULTS: One hundred and eighty-four adults (mean age 24 years, 53 % women, 90 % Caucasian) participated in the study. Nearly three in four adults (71 %) had 25(OH)D level <30 ng/ml and 26 % were vitamin D-deficient. In multivariate analysis, persons reporting a suntan (OR = 0.24, 95 % CI 0.09, 0.63, P = 0.004), tanning booth use (OR = 0.09, 95 % CI 0.02, 0.43, P = 0.002) and daily ingestion of two or more servings of milk (OR = 0.21, 95 % CI 0.09, 0.48, P < 0.001) were less likely to be deficient. These three questions provided a sensitivity and specificity of 79 % and 78 %, respectively, for the presence of deficiency. CONCLUSIONS: The questionnaire is moderately useful to identify young adults likely to be vitamin D-deficient. Additional revisions of the questionnaire may improve its ability to predict vitamin D deficiency.

Osteoporotic fractures in older women.

A case review of postmenopausal osteoporosis is presented in the context of recent literature in the field. Given the case patient's high risk for future fracture, a thorough workup and pharmacologic intervention are reasonable. Etiology of the patient's disease is explored, particularly vitamin D insufficiency, low body weight, smoking history, celiac sprue, use of glucocorticoids, and estrogen status. Means of reducing fracture risk include lifestyle changes, calcium and vitamin D repletion, antiresorptive therapy, and patient education. Development of new therapies to further reduce fracture risk in such individuals, and efficient strategies to target interventions toward those at highest risk, are needed.

Evaluation and measurement of bone mass.

Patients taking antiepileptic drugs (AEDs) have an increased risk for osteoporosis and osteoporotic fractures. Bone mineral density (BMD) is the best predictor of fracture risk. Measurement of BMD allows the identification of patients at risk before they suffer a fracture. The current "gold standard" for the measurement of BMD and diagnosis of osteopenia and osteoporosis is dual-energy X-ray absorptiometry. Clinicians should be familiar with the ways in which bone mass measurements are reported and should understand how to use BMD measurements in making treatment decisions and monitoring treatment. They should also be aware of current controversies, including the role of peripheral versus central BMD measurements and the use of different reference databases for different patient groups. Laboratory assessment to identify secondary causes of osteoporosis, such as low vitamin D status in patients taking AEDs, is useful, but the role of markers of bone turnover in clinical practice has not been well defined.

Outcomes and secondary prevention strategies for male hip fractures.

OBJECTIVE: To assess clinical outcomes and determine whether osteoporosis assessment and secondary prevention strategies were performed for male veterans hospitalized for hip fractures. DESIGN: Retrospective chart review for male veterans hospitalized for hip fracture from January 1993 through July 1999. SETTING: The Veterans Affairs Medical Center, Madison, WI. RESULTS: Medical charts were available for 46 of 53 male patients admitted for hip fracture during the study period. Three subjects were excluded because hip fracture was associated with high-impact trauma. Mean age of the 43 study patients was 72 years (range 43-91 y), and mean length of hospitalization was 16 days (median 11 d, range 3-108 d). Thirty-two (82%) of 39 veterans whose disposition was documented were discharged to a nursing home. Eleven (26%) of 43 men died within 12 months after fracture. Twelve (28%) had fractured previously. Four (10%) subsequently had another fracture. Three of 9 patients with documented ambulation status were ambulatory at 1 year. Three patients received a bone mass measurement within a prespecified time interval of 6 months subsequent to fracture. No patient's records included a diagnosis of osteoporosis either before or within 6 months after fracture. One-third of the patients had documentation of calcium or multivitamin supplementation at discharge. One patient was receiving calcitonin at the time of fracture and continued to receive it afterward. No other patient was prescribed antiresorptive therapy by the time of hospital discharge. CONCLUSIONS: Male veterans with hip fractures received inadequate evaluation and treatment for osteoporosis, although a substantial portion had documentation of recurrent fractures. Education of clinicians and creation of algorithms for management of established osteoporosis may improve outcomes for these individuals.

Osteoporosis screening by community pharmacists: use of National Osteoporosis Foundation resources.

OBJECTIVES: To assess the feasibility of establishing an osteoporosis screening program in rural community pharmacies based on information and resources provided by the National Osteoporosis Foundation (NOF), to survey primary care providers regarding the usefulness of this screening program, and to recommend strategies for pharmacists interested in working with patients at risk for osteoporosis. DESIGN AND PARTICIPANTS: Pharmacists and/or nurses enrolled women 65 years of age and older into the study, measured calcaneal bone density, administered a questionnaire to ascertain subjects' osteoporosis risk factors, and provided NOF literature to subjects. With their agreement, women's bone mass data and risk factor assessments were provided to primary care providers along with NOF's Physician's Guide to Prevention and Treatment of Osteoporosis. These providers were surveyed as to whether they found this information useful. SETTING: Five independent community pharmacies in rural Wisconsin. RESULTS: We enrolled and tested 133 women. Of these, 122 (92%) agreed to have information mailed to their primary health care providers. These 57 providers were surveyed and 24 (42%) responded; of these 24, 20 (83%) found the information they received useful. CONCLUSION: A community pharmacy-based osteoporosis screening program using NOF materials was well accepted by physicians. NOF resources and recommendations can provide a strong foundation for such programs.

Pharmacy-based bone mass measurement to assess osteoporosis risk.

OBJECTIVE: To evaluate elderly women's knowledge of their skeletal status, assess adequacy of calcium intake, determine the prevalence of low bone density, and determine whether peripheral bone density testing led to medical interventions in a group of rural, elderly Wisconsin women recruited in community pharmacies. DESIGN: Recruiting notices were posted in each pharmacy, and eligible women were enrolled in the order in which they volunteered. Each completed a fracture-risk questionnaire. Calcaneal bone density was measured within the following 6 weeks, using peripheral dual-energy X-ray absorptiometry. Mail surveys were used to assess interventions subsequent to the womens' study participation. SETTING: The study was conducted at 5 community pharmacies in rural Wisconsin. RESULTS: Of 133 women, 20% had calcaneal osteoporosis, defined as a T score < or =2.5 (calcaneal bone density <2.5 SDs below the young reference database). Thirty percent of women met National Osteoporosis Foundation (NOF) treatment criteria based on heel bone density and NOF-designated risk factors. Of those meeting treatment criteria, 75% were unaware of their low bone mass. Half of the women received <1200 mg/d of calcium, the recommended dose for osteoporosis prevention. Those who were taking a calcium supplement were much more likely to receive the recommended amount. Women who had discussed bone density test results with their physicians were more likely to receive central dual energy X-ray absorptiometry (DXA) measurements and/or start antiresorptive therapy than women who did not. CONCLUSIONS: Rural, elderly Wisconsin women are at substantial risk for osteoporosis, based on calcaneal bone density, but most are unaware of their risk. Compounding this risk is low calcium intake. Community screening of rural, elderly women by peripheral bone density measurement can lead to medical interventions in such individuals.
