RESUMEN
Increased ß-adrenergic receptor activity has been hypothesized to cause bone loss in those with dementia. We investigated the effect of long-term ß-blocker use on rate of bone loss in older adults with dementia. We used a linear mixed-effects model to estimate the relationship between long-term ß-blocker use and rate of bone loss in participants from the Health Aging and Body Composition study. Records of 1198 participants were analyzed, 44.7% were men. Among the men, 25.2% had dementia and 20.2% were on ß-blockers, while in the women, 22.5% had dementia and 16.6% received ß-blockers. In the 135 men with dementia, 23 were taking ß-blockers, while 15 of 149 women with dementia were using ß-blockers. In men with dementia, ß-blocker users had 0.00491 g/cm2 less bone mineral density (BMD) loss per year at the femoral neck (i.e., 0.63% less loss per year) than non-users (p < 0.05). No differences were detected in women with or without dementia and men without dementia. ß-blockers may be protective by slowing down bone loss in older men with dementia.

Assisted living facility (ALF) residents are at greater risk of declining health and death from coronavirus disease 2019 (COVID-19) due to advanced age, frailty, chronic conditions, and transmission prevention methods. One method, room quarantine, can lead to isolation and potential weight changes. Continuous room quarantine was mandated by the state for all nursing home and ALF residents. The objective of the current study was to determine the degree and significance of weight loss during quarantine through retrospective chart review and use these findings to guide a quality improvement project. Pre-and post-COVID-19 weights were compared for 53 house call program residents. Descriptive statistics and logistic regression were used. This small convenience sample demonstrated significant weight loss for 40% of ALF residents quarantined during the COVID-19 pandemic. Males showed a greater risk of significant weight loss. Weight loss of 5% in 1 month is considered problematic in older adults. As quarantine measures continue to be used for COVID-19 outbreaks, weight changes, particularly among males, need to be monitored and reported for intervention.

INTRODUCTION: Major depression is a common disorder affecting millions of adults each year. Many population-based surveys showed an increase in the number people with symptoms of depression at the onset of the COVID-19 pandemic. Our aim was to determine and compare the prevalence of depression risk in a primary care setting before and during the COVID-19 pandemic. METHODS: We conducted a cross-sectional study based on retrospective review of medical records from a large suburban primary care clinic. Records of adults 18 years and older, seen between January 1, 2019 and December 31, 2020 and who had also been screened for depression using the 9-item Patient Health Questionnaire (PHQ-9) were analyzed. RESULTS: Adults 18 years and older who completed the PHQ-9 assessment in 2019 and 2020 were 5078 and 4338, respectively. Risk of depression was 18.2% in 2019 and 14.8% in 2020 (P < .001). In adults under 50 years and those 50 years and older, depression risk was 20.7% versus 15.3% in 2019 (P < .001) and 17.3% versus 12.6% in 2020 (P < .001), respectively. In females, depression risk was 20.0% in 2019 and 16.8% in 2020 (P < .01), and in males, 14.1% in 2019 and 10.6% in 2020 (P < .01). CONCLUSION: Although our results did not reflect the published literature reporting a higher prevalence of depression during the COVID-19 pandemic, they were consistent with reports of increased risk in females and younger adults.

Chronic inflammatory back pain (CIBP) occurs in up to one-third of those with chronic back pain. Criteria for diagnosis of inflammatory back pain include an onset below 50 years. Using the US National Health and Nutrition Examination Survey data for 2009-2010, we showed that 3% of adults aged 50-69 years have features of CIBP with onset on or after 50 years. There is little information in the literature on CIBP of late onset. Patients with late onset CIBP may be falling through the cracks.

OBJECTIVES: To evaluate the 30-day hospital readmission rate, reasons, and risk factors for patients with cancer who were discharged to home setting after acute inpatient rehabilitation. DESIGN, SETTING, AND PARTICIPANTS: This was a secondary retrospective analysis of participants in a completed prospective survey study that assessed the continuity of care and functional safety concerns upon discharge and 30 days after discharge in adults. Patients were enrolled from September 5, 2018, to February 7, 2020, at a large academic quaternary cancer center with National Cancer Institute Comprehensive Cancer Center designation. MAIN OUTCOMES AND MEASURES: Thirty-day hospital readmission rate, descriptive summary of reasons for readmissions, and statistical analyses of risk factors related to readmission. RESULTS: Fifty-five (21%) of the 257 patients were readmitted to hospital within 30 days of discharge from acute inpatient rehabilitation. The reasons for readmissions were infection (20, 7.8%), neoplasm (9, 3.5%), neurological (7, 2.7%), gastrointestinal disorder (6, 2.3%), renal failure (3, 1.1%), acute coronary syndrome (3, 1.1%), heart failure (1, 0.4%), fracture (1, 0.4%), hematuria (1, 0.4%), wound (1, 0.4%), nephrolithiasis (1, 0.4%), hypervolemia (1, 0.4%), and pain (1, 0.4%). Multivariate logistic regression modeling indicated that having a lower locomotion score (OR = 1.29; 95% CI, 1.07-1.56; p = 0.007) at discharge, having an increased number of medications (OR = 1.12; 95% CI, 1.01-1.25; p = 0.028) at discharge, and having a lower hemoglobin at discharge (OR = 1.31; 95% CI, 1.03-1.66; p = 0.031) were independently associated with 30-day readmission. CONCLUSION AND RELEVANCE: Among adult patients with cancer discharged to home setting after acute inpatient rehabilitation, the 30-day readmission rate of 21% was higher than that reported for other rehabilitation populations but within the range reported for patients with cancer who did not undergo acute inpatient rehabilitation.

BACKGROUND AND OBJECTIVE: The decision to initiate anticoagulation in older adults with atrial fibrillation is complicated by the benefit of ischemic stroke prevention vs the risk of falls resulting in major bleeds. The objective of this study was to assess the impact of different treatments including direct oral anticoagulants on quality-adjusted life-years (QALYs) in patients aged 75 years and older with atrial fibrillation in the context of falls. METHODS: A Markov decision process was constructed for older patients with atrial fibrillation taking no anti-thrombotic, aspirin, warfarin, rivaroxaban, and apixaban. Input probabilities for clinical events were estimated from the available literature. One-way and two-way sensitivity analyses were performed by measuring the impact of varying input probabilities of clinical events on QALY outcomes. RESULTS: The base-case scenario estimated that older adults treated with no anti-thrombotic, aspirin, warfarin, rivaroxaban, and apixaban had QALYs of 8.03, 8.69, 10.38, 11.02, and 11.56, respectively. The sensitivity analysis estimated that an older adult would need to fall over 45 (rivaroxaban) and 458 (apixaban) times per year for the QALY of a direct oral anticoagulant to be lower than that of aspirin. CONCLUSIONS: Older adults with atrial fibrillation benefit from stroke protection of anticoagulants, especially direct oral anticoagulants, even if they are at high risk of falls. Clinicians should not consider fall risk as a deciding factor for withholding anticoagulation in this population of patients.

INTRODUCTION: In the absence of a cure, dementia is often managed by minimizing risk factors contributing to quality of life (QOL). Attitudes to dementia in older adults may differ from those in relatively younger adults. The aim was to conduct a systematic review of the literature to determine how QOL was assessed in adults, 65 years and older with dementia, and identify factors that influence the reported scores. METHODS: A systematic review of full-text articles addressing QOL in older adults with dementia, published in English from January 1995 to September 2020, was conducted using PubMed and PsycINFO. We included studies that assessed QOL and involved participants 65 years and older. Studies were evaluated for inclusion by 2 independent pairs of reviewers. We assessed the quality of the studies using the Joanna Briggs Institute's Critical Appraisal Checklist. Study characteristics and findings were summarized. Analysis was by narrative synthesis. We identified social and clinical factors influencing QOL scores. RESULTS: Of the 1,010 articles identified, 19 met the inclusion criteria. These 19 studies involved 6,279 persons with dementia, with sample sizes from 32 to 1,366. Mean age of participants ranged from 77.1 to 86.6 years. Five measurement tools were identified; Quality of Life in Alzheimer Disease (QOL-AD), Alzheimer Disease-Related Quality of Life (ADRQL), Quality of Life in Late-Stage Dementia (QUALID), QUALIDEM (a dementia-specific QOL tool), and DEMQOL (health-related QOL for people with dementia). Self-ratings of QOL were higher than proxy ratings. Factors commonly influencing self-ratings of QOL included depression, functional impairment, and polypharmacy. Common factors that influenced proxy ratings included functional impairment, presence of neuropsychiatric symptoms, cognitive impairment, and caregiver burden. CONCLUSION: In evaluating QOL in dementia, self- and proxy reports may complement each other to ensure that all perspectives are addressed.

BACKGROUND: Patients with cancer have been noted to have inadequate continuity of care after discharge from hospital. We sought to assess patient-reported continuity of care and functional safety concerns after acute inpatient rehabilitation. METHODS: This was a prospective study that used cross-sectional surveys at a National Cancer Institute Comprehensive Cancer Center. All patients who were admitted to acute inpatient rehabilitation from September 5, 2018, to February 7, 2020, met the inclusion criteria, and completed two surveys (assessing continuity of care and functional safety concerns) upon discharge and 1 month after discharge were included in the study. RESULTS: A total of 198 patients completed the study, and no major concerns were reported by the patients. The greatest concern was a lack of adequate communication management among different providers, reported by only 10 (5.0%) patients. The combined fall and near-fall rate within 1 month after discharge was (25/198) 13%. Brain metastasis, a comorbidity of depression, and a history of falls were significantly associated with a higher risk of falls or near falls within 1 month after discharge. CONCLUSION: Although overall patients with cancer reported adequate continuity of care and feeling safe to function at home after acute inpatient rehabilitation, it is important to be aware that fall or near-fall events within 1 month after acute inpatient rehabilitation are associated with brain metastasis, comorbidity of depression, and a history of falls. Thus, patients with these risk factors may benefit from including more focused fall prevention education and interventions. IMPLICATIONS FOR PRACTICE: Patients with cancer often have extensive problems that require care from multiple health care providers simultaneously, and a high level of coordination is needed for adequate transition of care from the inpatient to the outpatient setting. This transition of care period is prone to inadequate continuity of care and, for older adults, a particular risk for falls. Assessment for risk of fall is also an important factor to consider when evaluating patients to continue oncology treatments. There is a gap in knowledge regarding patient-reported continuity of care and functional safety concerns after acute inpatient cancer rehabilitation.

BACKGROUND: The association of geriatric syndromes and economic outcomes among patients who are undergoing transcatheter aortic valve replacement (TAVR) remains unknown. METHODS AND RESULTS: A retrospective observational study using the National Inpatient Sample (NIS) from 2011 to 2014 was conducted with 7078 patients who were 65 years or older and underwent TAVR. The average hospital cost was US$58 703 (± SD 29 777) and length of stay (LOS) was 8.1 days (±7.20). The rates of delirium, dementia, and frailty were 8.0%, 6.1%, and 10.5%, respectively. From a multivariable generalized linear regression, delirium increased the cost by 31.5% (95% CI 25.41~37.92) and LOS by 70.3% (95% CI 60.20~83.38). Frailty increased the cost by 7.4% (95% CI 3.44~11.53) and the LOS by 22.6% (95% CI 15.15~30.55). Dementia had no significant association with either outcome. When the interactions of the geriatric syndromes were tested for association with the outcomes, delirium in the absence of dementia but presence of frailty showed the strongest association with cost (increase by 45.1%, 95% CI 26.45~66.45), and delirium in the absence of both dementia and frailty showed the strongest association with LOS (increase by 74.5%, 95% CI 62.71~87.13). When the average hospital cost and LOS were predicted using the model with interaction terms, patients with delirium and frailty (but without dementia) had the highest value (total hospital cost US$86 503 and LOS 14.9 days). CONCLUSION: Among TAVR patients, delirium was significantly associated with increased hospital cost and LOS, and the association was significantly higher in the absence of dementia. The results of this study will be a great asset for health care providers and administrators in planning for efficient care strategy to lower health care expenditure in the hospital for older adults who underwent TAVR.
RESUMEN
Paget disease of bone is a benign disorder characterized by focal areas of increased bone turnover in one or more skeletal sites. It usually affects older adults, and men are at a higher risk than women. Any bone may be affected, but the disease has a high preference for the pelvis, spine, skull, and long bones. Pain is the most common symptom, and presentation of the disease may depend on which bones are affected, the extent of involvement, and the presence of complications. Paget disease of bone may be asymptomatic, and suspicion arises from incidental findings of elevated serum alkaline phosphatase levels on routine blood work or abnormalities on imaging tests performed for an unrelated cause. Evidence-based guidelines recommend the use of plain radiography and serum alkaline phosphatase testing for initial diagnosis and radionuclide scans for delineation of the extent of disease. Treatment with nitrogen-containing bisphosphonates is recommended in active disease or when risk of complications is possible. Complications of the disease include arthritis, gait changes, hearing loss, nerve compression syndromes, and osteosarcoma. Total serum alkaline phosphatase is the suggested marker for assessing treatment response when high bone turnover occurs, and it should be measured at three to six months to evaluate initial response. Early diagnosis of Paget disease of bone remains key to its management because patients generally have a good prognosis if treatment is initiated before major complications arise. The primary care physician may need to consult with a specialist for confirmation of diagnosis and initiation of treatment.

A higher drug burden index (DBI) is known to be associated with pre-admission falls leading to hospitalization. We investigated whether a mean difference in DBI (ΔDBI) between the events of in-hospital falls and hospital admission was associated with 30-day readmission in 113 patients ≥50 years who fell during their hospital stays between 2007 and 2014. A greater ΔDBI (≥0.09) was positively associated with higher 30-day readmission rates (incident rate ratio: 2.02; 95% confidence interval: 1.49-2.74). An effort to keep DBI low may thus decrease 30-day readmissions for older in-hospital fallers.

Introduction: Falls are the leading cause of accidental death in older adults. Each year, 28.7% of US adults over 65 years experience a fall resulting in over 300,000 hip fractures and $50 billion in medical costs. Annual fall risk assessments have become part of the standard care plan for older adults. However, the effectiveness of these assessments in identifying at-risk individuals remains limited. This study characterizes the performance of a commercially available, automated method, for assessing fall risk using machine learning. Methods: Participants (N = 209) were recruited from eight senior living facilities and from adults living in the community (five local community centers in Houston, TX) to participate in a 12-month retrospective and a 12-month prospective cohort study. Upon enrollment, each participant stood for 60 s, with eyes open, on a commercial balance measurement platform which uses force-plate technology to capture center-of-pressure (60 Hz frequency). Linear and non-linear components of the center-of-pressure were analyzed using a machine-learning algorithm resulting in a postural stability (PS) score (range 1-10). A higher PS score indicated greater stability. Participants were contacted monthly for a year to track fall events and determine fall circumstances. Reliability among repeated trials, past and future fall prediction, as well as survival analyses, were assessed. Results: Measurement reliability was found to be high (ICC(2,1) [95% CI]=0.78 [0.76-0.81]). Individuals in the high-risk range (1-3) were three times more likely to fall within a year than those in low-risk (7-10). They were also an order of magnitude more likely (12/104 vs. 1/105) to suffer a spontaneous fall i.e., a fall where no cause was self-reported. Survival analyses suggests a fall event within 9 months (median) for high risk individuals. Conclusions: We demonstrate that an easy-to-use, automated method for assessing fall risk can reliably predict falls a year in advance. Objective identification of at-risk patients will aid clinicians in providing individualized fall prevention care.
RESUMEN
OBJECTIVES: Patients with dementia are at high risk for hip fractures and often have poor outcomes when a fracture is sustained. Despite this poor prognosis, little data are available on what factors should be prioritized to guide surgical decision making in these cases. We aimed to understand the decision-making process for older dementia patients hospitalized after hip fractures. DESIGN: We performed a qualitative analysis of in-depth elite interviews conducted with a clinical care team involved in management of patients with dementia after hospitalization for hip fractures. SETTING: Interviews were conducted with an interprofessional team involved in the care of patients with dementia after being hospitalized for hip fractures. PARTICIPANTS: Interviewees included nine orthopaedic surgeons, three hospitalists, three geriatricians, five nurses, three occupational therapists, three physical therapists, and two clinical ethicists. MEASUREMENTS: Verbatim transcripts of the interviews were analyzed and coded using QSR International's NVivo 10 qualitative database management software. RESULTS: The three main themes that most interviewees discussed were pain control, functional status, and medical comorbidities. Interviewees brought up many factors related to restoring functional status including baseline functional status, rehabilitation potential, social support, and the importance of mobility. Dementia and its impact on rehabilitation potential were mentioned by all geriatricians. CONCLUSION: Although frailty, prognosis, and life expectancy were largely absent from the responses, the emphasis on dementia, advanced directives, and involving family or caregivers by the three geriatricians indicates the importance of including geriatricians in the decision-making team for these patients.

Coronary artery disease (CAD) and osteoporosis, the two most frequently occurring chronic diseases of aging populations, share many risk factors including lack of estrogen, smoking, and low physical activity. CAD and low bone mineral density (BMD) are strongly associated. Statins, (3-hydroxy-3-methylglutaryl coenzyme A [HMG-CoA] reductase inhibitors), are used to prevent and treat CAD and have been associated with high BMD. This cross-sectional study examined associations of BMD with statin use and nonuse in elderly women with or without CAD. Multivariate regression analyses were conducted on 185 women aged ≥60 years who were referred between October 2010 and March 2015 to a geriatric osteoporosis clinic in Houston, Texas, for compromised skeletal health. Compared to the control group (without CAD and without statin use), patients with CAD and no statin use were more likely to have lower femoral neck BMD (ß: -0.46, 95% confidence interval: -0.75 to -0.18). The BMD of patients taking statins, regardless of presence of CAD, was similar to that of the control group. Statins may be protective in preventing bone loss in elderly women suffering from CAD. Prospective trials are warranted to determine if continued use of statins in them would help prevent both CAD and bone loss.

Altered bone quality, caused by underlying metabolic changes of type 2 diabetes (T2D), has been hypothesized to cause altered bone strength and turnover leading to increased fracture risk in T2D patients. Current understanding about changes in bone turnover markers in T2D patients is mainly based on studies focused on Caucasian men and women. However, Hispanic populations have the highest prevalence of both T2D and osteoporosis in the US. We investigated associations of glycemic control (in terms of glycated hemoglobin [HbA1c]) and bone turnover rate in 69 older (≥50 years) Mexican American Cameron County Hispanic Cohort (CCHC) participants with T2D. Multivariable analyses were conducted to assess the associations between HbA1c (%), serum osteocalcin (OC), and serum sclerostin. In agreement with published reports from other racial/ethnic populations, our study found that lower bone turnover (indicated by lower serum OC) occurred in Mexican American men with T2D who had poorer glycemic control. For the women in our study, we found no significant association between glycemic control and OC. In contrast, HbA1c was positively associated with sclerostin for women, with near significance (p = 0.07), while no association was found in men. We recommend screening Mexican American individuals with T2D, specifically those with poor glycemic control, for bone loss and fracture risk.
RESUMEN
Trabecular bone score (TBS) is a texture parameter that measures the grayscale variation within dual-energy X-ray absorptiometry (DXA) images, and has been shown to significantly correlate with the 3-dimensional bone microarchitecture. The objective of this study was to determine whether TBS is a better clinical tool than traditionally used bone mineral density (BMD) to detect the skeletal deterioration seen in patients with diabetes (DM), patients undergoing oral glucocorticoid (GC) therapy, and patients who are both diabetic and taking steroids (GC + DM). We performed retrospective, cross-sectional study using DXA images of patients who visited UTHealth Department of Internal Medicine DXA clinic in Houston, TX, from May 30, 2014 to May 30, 2016. A total of 477 men and women, who were 55 years or older, were included in the study. Lumbar spine (LS) BMD and TBS were collected. Electronic medical records were reviewed to collect clinical information for each patient. When both men and women were analyzed as a single group, LS-BMD was significantly higher in the diabetic group than in the control group (1.14 vs 1.10, p = 0.038), whereas mean TBS of L1-L4 was significantly lower in the diabetic group (1.21 vs 1.26, p = 0.004). LS-TBS was also significantly lower in diabetic women than in nondiabetic women (1.20 vs 1.26, p = 0.002). Receiver operating characteristic curves and areas under the curve indicated that LS-TBS provided better ability than LS-BMD to discriminate between control subjects and those in the DM, GC, or GC + DM groups (areas under the curve between 0.645 and 0.697, p < 0.010 for all). LS-TBS is a BMD-independent parameter that is capable of capturing a larger portion of bone quality deterioration undetected by BMD alone in patients with DM and undergoing oral GC therapy.

Dietary protein has been shown to increase urinary Ca excretion in randomised controlled trials, and diets high in protein may have detrimental effects on bone health; however, studies examining the relationship between dietary protein and bone health have conflicting results. In the present study, we examined the relationship between dietary protein (total, animal and vegetable protein) and lumbar spine trabecular volumetric bone mineral density (vBMD) among participants enrolled in the Multi-Ethnic Study of Atherosclerosis (n 1658). Protein intake was assessed using a FFQ obtained at baseline examination (2000-2). Lumbar spine vBMD was measured using quantitative computed tomography (2002-5), on average 3 years later. Multivariable linear and robust regression techniques were used to examine the associations between dietary protein and vBMD. Sex and race/ethnicity jointly modified the association of dietary protein with vBMD (P for interaction = 0·03). Among white women, higher vegetable protein intake was associated with higher vBMD (P for trend = 0·03), after adjustment for age, BMI, physical activity, alcohol consumption, current smoking, educational level, hormone therapy use, menopause and additional dietary factors. There were no consistently significant associations for total and animal protein intakes among white women or other sex and racial/ethnic groups. In conclusion, data from the present large, multi-ethnic, population-based study suggest that a higher level of protein intake, when substituted for fat, is not associated with poor bone health. Differences in the relationship between protein source and race/ethnicity of study populations may in part explain the inconsistent findings reported previously.

Bone mineral density (BMD) and geometric bone measures are individually associated with prevalent osteoporotic fractures. Whether an aggregate of these measures would better associate with fractures has not been examined. We examined relationships between self-reported fractures and selected bone measures acquired by quantitative computerized tomography (QCT), a composite bone score, and QCT-acquired dual-energy X-ray absorptiometry-like total femur BMD in 2110 men and 2682 women in the Age, Gene/Environment Susceptibility-Reykjavik Study. The combined bone score was generated by summing gender-specific Z-scores for 4 QCT measures: vertebral trabecular BMD, femur neck cortical thickness, femur neck trabecular BMD, and femur neck minimal cross-sectional area. Except for the latter measure, lower scores for QCT measures, singly and combined, showed positive (p < 0.05) associations with fractures. Results remained the same in stratified models for participants not taking bone-promoting medication. In women on bone-promoting medication, greater femur neck cortical thickness and trabecular BMD were significantly associated with fracture status. However, the association between fracture and combined bone score was not stronger than the associations between fracture and individual measures or total femur BMD. Thus, the selected measures did not all similarly associate with fracture status and did not appear to have an additive effect on fracture status.

RATIONALE, AIMS AND OBJECTIVES: Increasing number of primary care visits for osteoporosis by older patients combined with new vitamin D screening recommendations necessitate primary care providers (PCPs) to identify and screen at-risk patients. We described prevalence and determinants of vitamin D screening among older patients treated for osteopoenia, osteoporosis and related fractures in academic outpatient primary care clinics (family medicine and geriatric medicine) in Houston, TX. METHODS: Electronic chart review collected data on patients ≥50 years old from January 2008 to December 2010. Orders for serum 25-hydroxy vitamin D indicated vitamin D screening. Differences in patient characteristics were described between the groups with and without vitamin D screening. Age, body mass index, racial/ethnic background, bone-promoting medication (BPM) use and clinic types (family medicine versus geriatric medicine) were determinants for vitamin D screening in the regression analysis. RESULTS: Patients were mostly women (95%), Caucasian (65%) and had a mean age of 69 ± 12 years. Twenty-two per cent of the family medicine clinic patients (total n = 78) and 51% of the geriatric medicine clinics patients (total n = 70) were screened. Older age (odds ratio, 0.94 confidence interval = 0.90-0.99) and BPM use (2.58, 1.03 to 6.45) were significant positive determinants for vitamin D screening. CONCLUSIONS: In primary care clinics, vitamin D screening remains low among patients diagnosed with osteopoenia, osteoporosis and fractures. In light of new guidelines, suboptimal screening in the vulnerable older patients is disturbing. We recommend increased PCPs' awareness about vitamin D screening guidelines for improving skeletal health in older patients.

BACKGROUND AND OBJECTIVES: Kidney Disease Improving Global Outcomes guidelines recommend against bone mineral density (BMD) screening in CKD patients with mineral bone disease, due to a lack of association of BMD with fractures in cross-sectional studies in CKD. We assessed whether BMD is associated with fractures in participants with and without CKD in the Health, Aging, and Body Composition study, a prospective study of well functioning older individuals. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Hip BMD was measured by dual-energy x-ray absorptiometry. Osteoporosis was defined as a femoral neck BMD (FNBMD) T score below -2.5 and CKD as an estimated GFR <60 ml/min per 1.73 m(2). The association of BMD with incident nonspine, fragility fractures to study year 11 was analyzed using Cox proportional hazards analyses, adjusting for age, race, sex, body mass index, hyperparathyroidism, low vitamin D level, and CKD. Interaction terms were used to assess whether the association of BMD with fracture differed in those with and without CKD. RESULTS: There were 384 incident fractures in 2754 individuals (mean age 73.6 years). Lower FNBMD was associated with greater fracture, regardless of CKD status. After adjustment, the hazard ratios (95% confidence intervals) were 2.74 (1.99, 3.77) and 2.15 (1.80, 2.57) per lower SD FNBMD for those with and without CKD, respectively (interaction P=0.68), and 2.10 (1.23, 3.59) and 1.63 (1.18, 2.23) among those with osteoporosis in patients with and without CKD, respectively (interaction P=0.75). CONCLUSIONS: BMD provides information on risk for fracture in older individuals with or without moderate CKD.
