Anti-osteoporosis medication dispensing by clinical commissioning groups in England - an ecological study of variability in practice and of the effect of the Covid-19 pandemic. Pharmacoepidemiol Drug Saf 2023; 32:248-255. [PMID: 36125097 PMCID: PMC10092162 DOI: 10.1002/pds.5544] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2022] [Revised: 08/18/2022] [Accepted: 09/16/2022] [Indexed: 01/26/2023]
Abstract
PURPOSE To investigate whether the rate of Anti-Osteoporosis Medication (AOM) dispensing was related to prevalence of risk factors and hip fracture incidence in the local population. METHODS The Open Prescribing database was used to analyse dispensed AOM at the level of Clinical Commissioning Groups (CCGs) in England. Male Healthy Life Expectancy (MHLE), Female Healthy Life Expectancy (FHLE), the prevalence of smoking and active adults, the incidence of hip fracture and of alcohol related hospital admissions, and local dispensing of a comparator drug (atorvastatin) were considered as predictor variables. Linear and multilinear regression were performed. Using atorvastatin as a comparator, AOM dispensing was compared after the start of the Covid-19 pandemic with the same quarter the previous year. RESULTS Rates of AOM per 1000 people aged over 65 years in a CCG area varied between 379.2 and 1129.1, with a mean of 670.3. Population risk factors were individually related to the amount of AOM dispensed in an area. Collectively, local activity levels in adults (p = 0.042) and local hip fracture incidence (p = 0.003) were significantly negatively correlated with rates of AOM dispensed. Rates of alendronate dispensing fell significantly at the start of the Covid-19 pandemic (p < 0.001), whilst atorvastatin dispensing rates significantly increased (p < 0.001). CONCLUSION Lower rates of AOM dispensing were seen in areas with a higher proportion of active adults and higher incidence of hip fracture. Multidisciplinary services should be developed to address this care gap with consideration given to local population risk factors. Community pharmacists are ideally placed to play a vital role in osteoporosis management.

The effect of social deprivation on fragility fracture of the distal radius. Injury 2019; 50:1232-1236. [PMID: 31076143 DOI: 10.1016/j.injury.2019.04.025] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/28/2018] [Revised: 04/24/2019] [Accepted: 04/28/2019] [Indexed: 02/02/2023]
Abstract
INTRODUCTION Social deprivation is associated with many adult fractures including distal radius fractures but the mechanisms for this are unclear. The aim of this study was to identify if social deprivation was associated with falls risk, mechanism of injury or osteoporosis in patients with a fragility fracture of the distal radius. METHOD Details of all patients aged 50 years and over presenting with a radiographically confirmed fracture of the distal radius over a one year period, were prospectively recorded. Patients were sent a questionnaire pack including questions regarding place and mechanism of injury, comorbidity assessment, falls risk assessment tool and FRAX assessment of bone health and fracture risk. RESULTS 333 out of 521 eligible patients completed the questionnaire (279 female; 54 male, response rate = 64%). There was no difference between characteristics of responders and non-responders (p = 0.58). DRF rate was higher in socially deprived quintiles (p = 0.040). Less falls occurred in the home in socially deprived patients (Q1/2: 35%: Q3-5: 48%, p = 0.037) with more falls outdoors (Q1/2: 39%: Q3-5: 24%, p = 0.001). There was no difference in height from which falls took place with most occurring from standing height (Q1/2: 81%: Q3-5: 86%, p = 0.336). Linear regression analysis found no relationship between social deprivation rank and FRAX scores (major fracture risk: p = 0.274, hip fracture risk: p = 0.283) but demonstrated a significant relationship between social deprivation and increased number of falls risk factors (p = 0.002). Mean number of falls risk factors was higher in the two most socially deprived quintiles (Q1/2: 3.62: Q3-5: 2.79, p = 0.028). CONCLUSION We have identified increased falls risk as an important reason for DRF in socially deprived patients. Knowing which patients are at highest risk allows interventions to be efficiently targeted. We would recommend resources should be targeted towards patients from socially deprived areas and focused on specific falls prevention strategies.

Abstract
INTRODUCTION Social deprivation has been shown to be associated with increased incidence of many types of fracture but the causes for this have not been established. The aim of this study was to establish if distal radius fracture was associated with deprivation and investigate reasons for this. METHOD Data was reviewed of 4463 adult patients who attended our Emergency Department over a four year period. The Index of Multiple Deprivation was used to measure deprivation for each patient. Modelling techniques were used to investigate the relationship between fracture rate and deprivation, gender, ethnicity and age. RESULTS Distal radius fracture rate was higher for patients in more deprived quintiles. Mean age in the most deprived two quintiles was 54.4 years compared to 60.1 years in the least deprived three quintiles. Modelling showed important differences between ethnic groups. Deprivation was an independent risk factor for distal radius fracture only in white patients. Deprived white women had a lower second metacarpal cortical index than women of other ethnicities suggesting increased bone fragility. Being male is a risk factor for fracture when deprivation, ethnicity and age are taken into account. Incidence rate ratio of the least deprived quintile compared to the most deprived was 0.33 (95% CI: 0.30-0.37) for white men and 0.47 (95% CI: 0.44-0.49) for white women. CONCLUSION Effective interventions exist to prevent further fragility fracture and this work allows geographical areas at risk to be identified. Presentation with a distal radius fracture provides an opportunity to implement interventions. In the current economic climate resources are scarce and must be used prudently. Resources should be targeted to those at risk patients from deprived areas and preventative strategies put in place.

Abstract
BACKGROUND Osteoporosis has been considered a disease that primarily affects women, but recently male osteoporosis is also attracting attention. This study aims to comparatively analyze socioeconomic and other factors that are related to the prevalence of osteoporosis in both men and women. MATERIALS AND METHODS This study used data from the Korean Community Health Survey conducted in 2013. To determine factors related to osteoporosis prevalence, researchers applied a binary logistic regression model, first for all research participants, then separately for male and female participants. RESULTS Women were more likely than men to have osteoporosis (odds ratio 12.33, 95% confidence interval 11.55-13.17). Factors related to osteoporosis prevalence included age, education level, region, economic activity, alcohol consumption, salt intake, depression, and body mass index in both genders. Low education and income levels were more highly associated with osteoporosis prevalence in women than in men. CONCLUSIONS Most of the factors were not gender specific, but some socioeconomic determinants varied by gender. Future studies that will focus on the effects of socioeconomic factors on osteoporosis, as well as gender-related differences in prevention and control of osteoporosis, are needed.

Abstract
PURPOSE The aim of this study in adult patients with a distal radial fracture was to determine whether socioeconomic status influenced the epidemiology, mechanism of injury, fracture severity, or the outcome according to function, radiographic assessment, and rate of associated complications. METHODS We identified 3983 distal radial fractures over a 7-year period. Socioeconomic status was assigned using the Carstairs score, and the population was divided into quintiles depending on deprivation. Patient demographics, mechanism of injury, fracture severity, and radiographic assessment at time of injury were assessed for epidemiological differences according to social quintile. Functional outcome was assessed using grip strength, Moberg pickup test, return to normal use of the hand, and range of movement. Radiographs were assessed at 1 week, 6 weeks, and 1 year. Complications were defined as malunion, carpal tunnel syndrome, complex regional pain syndrome (CRPS), persistent pain, and subjective cosmetic deformity of the wrist. RESULTS Socioeconomically deprived patients were significantly younger (p < 0.001) and more likely to be male (p = 0.017); after adjusting for confounding factors, deprived patients were 3.1 (95% CI 1.4-4.7) years younger than the most affluent patients (p < 0.001). Deprived patients were more likely to sustain their fracture by a high-energy mechanism (p = 0.004). There were no significant differences between quintiles in outcome. There was a significantly greater prevalence of CRPS in more affluent patients (p = 0.004). CONCLUSIONS Socioeconomically deprived patients sustaining a distal radial fracture are more likely to be younger and male. Outcome is not influenced by socioeconomic status, but the prevalence of CRPS is greater in more affluent patients.

Abstract
The aims of this study were to examine the association between different types of arthritis and falls and to investigate whether clinically significant depression symptoms (CSDS) moderate these relationships. The study used nationally representative data from the 2008 Health and Retirement Study ( n = 7,715, M age = 75, 62% female, and 90% White). Among the respondents, 42% experienced at least one fall during the previous 2 years. About one third had some form of arthritis: 22% osteoarthritis (OA), 4.8% rheumatoid arthritis (RA), 2.3% both OA and RA, and 7.9% with other arthritis types. About one fifth of respondents had CSDS. OA and CSDS are associated with the odds of falling (17% and 29%, respectively), adjusting for socio-demographic characteristics, lifestyle, health conditions, and psychiatric medications. There was no statistically significant interaction between types of arthritis and CSDS. Health care providers should pay attention to managing arthritis, especially OA, and CSDS to prevent falls among older adults.

Abstract
Aims This study explores the epidemiology of patients with a fracture of the scaphoid presenting to a regional teaching hospital. Patients and Methods All patients with a confirmed fracture of the scaphoid over a retrospective period between January 2010 and May 2013 were included. Their demographics, deprivation status and when the fracture occurred was noted and assessed. There were 415 fractures in 365 males and 50 females. Results The incidence of fracture of the scaphoid was 12.4 in 100 000 each year in the general population. The mean age of the patients was 22 years (nine to 35); the highest incidence was in males aged between 15 and 19 years. We calculate the annual incidence in the United Kingdom to be 7265 each year. Patients with the lowest socioeconomic status had an incidence of 18.57 in 100 000 whereas the least deprived patients had an incidence of 9.98 (p < 0.001). There was evidence of a seasonal trend (p = 0.022) with the highest monthly rate found in June (16.96 in 100 000 each year) and the lowest was in December (7.61 in 100 000 each year). There were significantly fewer presentations of fracture at the weekend (p < 0.001), and the highest incidence was on Mondays. Most fractures occurred at the waist (64%) and tubercle (18.1%). Take home message: In this large-scale epidemiological study, we confirmed that young men are most at risk of sustaining a fracture of the scaphoid, and report new factors in relation to social deprivation and seasonality that influence scaphoid fractures.

FRAX predicts incident falls in elderly men: findings from MrOs Sweden. Osteoporos Int 2016; 27:267-74. [PMID: 26391036 DOI: 10.1007/s00198-015-3295-7] [Citation(s) in RCA: 32] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/27/2015] [Accepted: 08/13/2015] [Indexed: 12/31/2022]
Abstract
UNLABELLED Falls and fractures share several common risk factors. Although past falls is not included as an input variable in the FRAX calculator, we demonstrate that FRAX probability predicts risk of incident falls in the MrOs Sweden cohort. INTRODUCTION Although not included in the FRAX® algorithm, it is possible that increased falls risk is partly dependent on other risk factors that are incorporated into FRAX. The aim of the present study was to determine whether fracture probability generated by FRAX might also predict risk of incident falls and the extent that a falls history would add value to FRAX. METHODS We studied the relationship between FRAX probabilities and risk of falls in 1836 elderly men recruited to the MrOS study, a population-based prospective cohort of men from Sweden. Baseline data included falls history, clinical risk factors, bone mineral density (BMD) at femoral neck, and calculated FRAX probabilities. Incident falls were captured during an average of 1.8 years of follow-up. An extension of Poisson regression was used to investigate the relationship between FRAX, other risk variables, and the time-to-event hazard function of falls. All associations were adjusted for age and time since baseline. RESULTS At enrolment, 15.5 % of the men had fallen during the preceding 12 months (past falls) and 39 % experienced one or more falls during follow-up (incident falls). The risk of incident falls increased with increasing FRAX probabilities at baseline (hazard ratio (HR) per standard deviation (SD), 1.16; 95 % confidence interval (95%CI), 1.06 to 1.26). The association between incident falls and FRAX probability remained after adjustment for past falls (HR per SD, 1.12; 95%CI, 1.03 to 1.22). High compared with low baseline FRAX score (>15 vs <15 % probability of major osteoporotic fracture) was strongly predictive of increased falls risk (HR, 1.64; 95%CI, 1.36 to 1.97) and remained stable with time. Whereas past falls were a significant predictor of incident falls (HR, 2.75; 95%CI, 2.32 to 3.25), even after adjustment for FRAX, the hazard ratio decreased markedly with increasing follow-up time. CONCLUSIONS Although falls are not included as an input variable, FRAX captures a component of risk for future falls and outperforms falls history with an extended follow-up time.

Abstract
Background Osteoporosis and associated fragility fractures are a major health problem; they are more common in women over 50 years old. Fracture liaison nurses have been widely used in secondary care to promote the recognition of fragility fractures and to promote the use of bone-sparing medication to reduce the risk of recurrent facture. Objective Audit the impact of a primary care based fracture liaison nurse on the detection of fragility fractures in people with osteoporosis and their treatment with a bone-sparing medication. Method This audit took place in 12 GP practices using ‘before and after’ cross-sectional extractions of anonymised routine data. We report, for females 50–74 years and ≥75 years old, socio-economic deprivation index, the prevalence of osteoporosis, recording of fragility fractures, dual-energy X-ray absorptiometry (DXA), smoking, and body-mass index (BMI) and use of appropriate bone-sparing medication. We used Altman’s test of independent proportions to compare before and after data. Results Recording of the diagnosis of osteoporosis increased from 1.5% to 1.7% (p = 0.059); the rate of DXA scans fell (1.8% to 1.4%; p = 0.002); recording of fractures and fragility fractures more than doubled (0.8% to 2.0%; p<0.001 and 0.5% to 1.5%; p<0.001, respectively) with approximate doubling of the recording of smoking, and BMI (p<0.001 level). Fragility fracture recording rose from 8.8% to 15% in females aged 50 to 74, and from 0.8% to 2.3% in people aged ≥75years old (p<0.001). There appeared to be inequity in the service, people who were least deprived were more likely to receive DXA scans and the more deprived to be prescribed bone sparing agents. Conclusion A fracture liaison nurse in primary care has been associated with a period of improved management. Liaison nurses based in different parts of the health system should be tested in a prospective trial.

Abstract
BACKGROUND This study aims to better understand the relationship between socioeconomic status (SES), fractures in those that attend an outpatient fracture clinic and a diagnosis of osteoporosis. This will further aid our ability to risk stratify patients' with fractures for further investigation and secondary management of their bone health. METHOD This is a cross sectional analysis using data from the Nottingham Fracture Liaison Service of patients attending the outpatient fracture clinic from 1/01/08 to 31/12/11. Logistic regression adjusted for age and gender were used to investigate SES, fractures and a diagnosis of osteoporosis. Fisher's exact test was used to compare DXA attendance in those living in most deprived and least deprived area. A cut off of 65 years was used to conduct subset analysis of a younger and an older group. RESULTS 6362 patients (1346 male, 5016 female; mean (SD) age, 69 (12)) were included in the study. There was no relationship between SES, proportion of fracture types and having a diagnosis of osteoporosis. Prevalence of osteoporosis in each SES quintile from 1 (most deprived) to 5 (least deprived) was 26.68%, 29.04%, 24.83%, 25.67% and 26.68% respectively. The least deprived quintile compared with the most deprived was not associated with a diagnosis of osteoporosis (OR 0.97; 95% CI 0.76-1.25, p=0.837). Those living in the most deprived area were less likely to attend their bone density scan appointment compared to those living in the least deprived area (OR 0.56; 95% CI 0.44-0.7, p<0.0001). CONCLUSION This study has shown that there is no relationship between SES, fracture types and a diagnosis of osteoporosis in those that present to the fracture clinic. SES should not be used to risk stratify patients for further bone health management after fractures. Those living in the most deprived areas are less likely to attend their bone density scan and efforts need to be made to improve attendance in this group.

Abstract
Fractures of the tibial shaft are common injuries, but there are no long-term outcome data in the era of increased surgical management. The aim of this prospective study was to assess the clinical and functional outcome of this injury at 12 to 22 years. Secondary aims were to determine the short- and long-term mortality, and if there were any predictors of clinical or functional outcome or mortality. From a prospective trauma database of 1502 tibial shaft fractures in 1474 consecutive adult patients, we identified a cohort of 1431 tibial diaphyseal fractures in 1403 patients, who fitted our inclusion criteria. There were 1024 men, and mean age at injury was 40.6 years. Fractures were classified according to the AO system, and open fractures graded after Gustilo and Anderson. Requirement of fasciotomy, time to fracture union, complications, incidence of knee and ankle pain at long-term follow-up, changes in employment and the patients’ social deprivation status were recorded. Function was assessed at 12 to 22 years post-injury using the Short Musculoskeletal Function Assessment and short form-12 questionnaires. Long-term functional outcome data was available for 568 of the surviving patients, 389 were deceased and 346 were lost to follow-up. Most fractures (90.7%, n = 1363) united without further intervention. Fasciotomies were performed in 11.5% of patients; this did not correlate with poorer functional outcome in the long term. Social deprivation was associated with a higher incidence of injury but had no impact on long-term function. The one-year mortality in those over 75 years of age was 29 (42%). At long-term follow-up, pain and function scores were good. However, 147 (26%) reported ongoing knee pain, 62 (10%) reported ankle pain and 97 (17%) reported both. Such joint pain correlated with poorer functional outcome. Cite this article: Bone Joint J 2014;96-B:1370–7.

Abstract
BACKGROUND Effects of neighborhood contextual features have been found for many diseases, including bone fractures in adults. Our study objective was to evaluate the association between neighborhood characteristics and pediatric bone fracture rates. We hypothesized that neighborhood indices of deprivation would be associated with higher fracture rates. MATERIALS AND METHODS Pediatric bone fracture cases treated at a tertiary, academic, urban pediatric emergency department between 2003 and 2006 were mapped to census block groups using geographical information systems software. Fracture rates were calculated as fractures per 1000 children in each census block. Exploratory factor analysis of socioeconomic indicators was performed using 2000 census block data. Factor scores were used to predict odds of bone fracture at the individual level while adjusting for mean age, sex composition, and race/ethnicity composition at census block level using our sample data. RESULTS We analyzed 3764 fracture visits in 3557 patients representing 349 distinct census blocks groups. Fracture rates among census blocks ranged from 0 to 207 per 1000 children/study period. Logistic regression modeling identified 2 factors (race/education and large families) associated with increased fracture risk. Census variables reflecting African American race, laborer/service industry employment, long-term block group residence, and lower education levels strongly loaded on the race/education factor. The large families factor indicated the children-to-families ratio within the block group. The poverty factor was not independently associated with fracture risk. CONCLUSIONS Thus, neighborhood characteristics are associated with risk for fractures in children. These results can help inform translational efforts to develop targeted strategies for bone fracture prevention in children.

[PMID: 24529318 DOI: 10.1016/j.maturitas.2013.12.011] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2013] [Revised: 12/08/2013] [Accepted: 12/22/2013] [Indexed: 12/30/2022]
Abstract
OBJECTIVES First, to study the difference between two groups of postmenopausal women living in different population centres (rural vs urban) in the prevalence of osteoporosis, fragility fractures and factors which may influence them: hypovitaminosis D, bone mineral density, coexistence of other diseases which predispose to their appearance; secondly, to observe the influence of low socioeconomic status, categorised as poverty. STUDY DESIGN 1229 postmenopausal women were studied, of whom 390 (31.7%), were living in rural areas and 839 (68.3%), in urban areas. Data regarding risk factors related to osteoporosis were obtained, and, among other biochemical measures, 25 hydroxyvitamin D and parathyroid hormone were determined. Bone densitometry was carried out in the lumbar spine and proximal femur, as well as lateral X-rays of the dorsal and lumbar spine. RESULTS The women who lived in rural areas were older, shorter, heavier and had a higher body mass index than those from urban areas. Among the women from rural areas there was a higher prevalence of poverty, and higher levels of obesity, arterial hypertension and diabetes mellitus were observed, as well as a higher prevalence of densitometric osteoporosis. The rural women had lower values of bone mineral density in the lumbar spine and a higher prevalence of vertebral fractures and hypovitaminosis D. The variables which were associated independently with living in rural areas were poverty, obesity, vertebral fractures, BMD in the lumbar spine and levels of 25 hydroxyvitamin D. CONCLUSIONS In our study, postmenopausal women who live in rural populations have more poverty, lower values of vitamin D, lower BMD in the lumbar spine and a higher prevalence of vertebral fractures and of osteoporosis. The higher prevalence of obesity, arterial hypertension and diabetes mellitus observed in these women may be adjuvant factors, all fostered by their socioeconomic state of poverty.

Abstract
UNLABELLED We investigated the fracture risk assessment tool (FRAX) Canada calibration and discrimination according to income quintile in 51,327 Canadian women, with and without a competing mortality framework. Our data show that, under a competing mortality framework, FRAX provides robust fracture prediction and calibration regardless of socioeconomic status (SES). INTRODUCTION FRAX® predicts 10-year fracture risk. Social factors may independently affect fracture risk. We investigated FRAX calibration and discrimination according to SES. METHODS Women aged ≥50 years with baseline femoral neck bone mineral density (BMD) were identified from the Manitoba Bone Density Program, Canada (n = 51,327), 1996-2011. Mean household income, extracted from 2006 census files, was categorized into quintiles. Ten-year fracture probabilities were calculated using FRAX Canada. Incident non-traumatic fractures were studied in relation to income quintile in adjusted Cox proportional hazards models. We compared observed versus predicted fractures with and without a competing mortality framework. RESULTS During mean 6.2 ± 3.7 years of follow up, there were 6,392 deaths, 3,723 women with ≥1 major osteoporotic fracture (MOF), and 1,027 with hip fractures. Lower income was associated with higher risk for death, MOF, and hip fracture in adjusted models (all p < 0.005). More women in income quintile 1 (lowest) versus quintile 5 experienced death (19 vs. 8%), MOF (10 vs. 6%), or hip fracture (3.0 vs. 1.3 %) (all p ≤ 0.001). Adjustment for competing mortality mitigated the effect of SES on FRAX calibration, and good calibration was observed. FRAX provided good fracture discrimination for MOF and hip fracture within each income quintile (all p < 0.001). Area under the curve was slightly lower for income quintiles 1 versus 5 for FRAX with BMD to predict MOF (0.68, 95% CI 0.66-0.70 vs. 0.71, 95% CI 0.69-0.74) and hip fracture (0.79, 95% CI 0.76-0.81 vs. 0.87, 95% CI 0.84-0.89). CONCLUSION Increased fracture risk in individuals of lower income is offset by increased mortality. Under a competing mortality framework, FRAX provides robust fracture prediction and calibration regardless of SES.

Abstract
We investigated the prevalence and risk factors of vertebral fractures in Korea. In a community-based prospective epidemiology study, 1,155 men and 1,529 women (mean age 59 years, range 43-74) were recruited from Ansung, a rural Korean community. Prevalent vertebral fractures were identified on the lateral spinal radiographs at T11 to L4 using vertebral morphometry. Bone mineral density (BMD) was measured at the lumbar spine, femur neck and total hip. Of the 2,684 subjects, 137 (11.9%) men and 227 (14.8%) women had vertebral fractures and the standardized prevalence for vertebral fractures using the age distribution of Korean population was 8.8% in men and 12.6% in women. In univariate analysis, older age, low hip circumference, low BMD, low income and education levels in both sexes, previous history of fracture in men, high waist-to-hip circumference ratio, postmenopausal status, longer duration since menopause, and higher number of pregnancies and deliveries in women were associated with an increased risk of vertebral fractures. However, after adjusting for age, only low BMD in both sexes and a previous history of fracture in men were significantly associated with an increased risk of vertebral fractures. Vertebral fractures are prevalent in Korea as in other countries. Older age, low BMD and a previous history of fracture are significant risk factors for vertebral fractures.

Abstract
SUMMARY The association between socioeconomic status (SES) and bone health, specifically in men, is unclear. Based upon data from the large prospective Concord Health in Ageing Men Project (CHAMP) Study of community-dwelling men aged 70 years or over, we found that specific sub-characteristics of SES, namely, marital status, living circumstances, and acculturation, reflected bone health in older Australian men. INTRODUCTION Previous studies reported conflicting results regarding the relationship between SES and bone health, specifically in men. The main objective of this study was to investigate associations of SES with bone health in community-dwelling men aged 70 years or over who participated in the baseline phase of the CHAMP Study in Sydney, Australia. METHODS The Australian Socioeconomic Index 2006 (AUSEI06) based on the Australian and New Zealand Standard Classification of Occupations was used to determine SES in 1,705 men. Bone mineral density and bone mineral content (BMC) were determined by dual-energy X-ray absorptiometry. Bone-related biochemical and hormonal parameters, including markers of bone turnover, parathyroid hormone, and vitamin D, were measured in all men. RESULTS General linear models adjusted for age, weight, height, and bone area revealed no significant differences across crude AUSEI06 score quintiles for BMC at any skeletal site or for any of the bone-related biochemical measures. However, multivariate regression models revealed that in Australian-born men, marital status was a predictor of higher lumbar BMC (β = 0.07, p = 0.002), higher total body BMC (β = 0.05, p = 0.03), and lower urinary NTX-I levels (β=-0.08, p = 0.03), while living alone was associated with lower BMC at the lumbar spine (β=-0.05, p = 0.04) and higher urinary NTX-I levels (β=0.07, p = 0.04). Marital status was also a predictor of higher total body BMC (β = 0.14, p = 0.003) in immigrants from Eastern and South Eastern Europe. However, in immigrants from Southern Europe, living alone and acculturation were predictors of higher femoral neck BMC (β = 0.11, p = 0.03) and lumbar spine BMC (β = 0.10, p = 0.008), respectively. CONCLUSIONS Although crude occupation-based SES scores were not significantly associated with bone health in older Australian men, specific sub-characteristics of SES, namely, marital status, living circumstances, and acculturation, were predictors of bone health in both Australia-born men and European immigrants.

Abstract
UNLABELLED This study assesses the possible association between poverty and osteoporosis and/or fragility fractures in a population of postmenopausal women. We found that postmenopausal women with low socioeconomic status had lower values of BMD at the lumbar spine, a higher prevalence of densitometric osteoporosis, and a higher prevalence of total and vertebral fractures. INTRODUCTION Some lifestyles are related to the presence of osteoporosis and/or fragility fractures, whereas poverty is related to some lifestyles. Because of this, we studied the possible association of poverty with osteoporosis and fractures. METHODS This was an observational, cross-sectional study performed in the Canary Islands, Spain. Participants consisted of a total of 1,139 ambulatory postmenopausal women aged 50 years or older with no previous osteoporosis diagnosis and who were enrolled in some epidemiological studies. The prevalence of fractures (vertebral and non-vertebral) and the prevalence of osteoporosis (T-score <-2.5 either at the lumbar spine or the femoral neck). A previously validated questionnaire elicited the most important risk factors for osteoporosis: socioeconomic status, defined by the annual income was also assessed by a personal interview. A dorso-lateral X-ray of the spine was performed, and bone mineral density (BMD) was measured by DXA in the lumbar spine (L2-L4) and proximal femur. RESULTS Compared to women with a medium and high socioeconomic status (n = 665), those who were classified into poverty (annual family income lower than 6,346.80 Euros, in a one-member family, n = 474), were older and heavier and had lower height, lower prevalence of tobacco and alcohol consumption, lower use of HRT and higher use of thiazides. After correcting for age and body mass index (BMI), women in poverty had lower spine BMD values than women with a medium and high socioeconomic status (0.840 g/cm(2) vs. 0.867 g/cm(2), p = 0.005), but there were no statistical differences in femoral neck BMD between groups. The prevalence of osteoporosis was also higher in women in poverty [40.6% vs. 35.6%, (OR 1.35, CI 95%: 1.03; 1.76)] after adjusting by age and BMI. Moreover, 37.8% of women in poverty had a history of at least one fragility fracture compared to 27.7% of women not in poverty (OR: 1.45, CI 95%: 1.11; 1.90). The prevalence of vertebral fractures was also higher in women in poverty 24.7% vs. 13.4%, (OR 2.01, CI 95%: 1.44; 2.81). CONCLUSIONS Postmenopausal women with low socioeconomic status had lower values of BMD at the lumbar spine, and a higher prevalence of densitometric osteoporosis, and a higher prevalence of total and vertebral fractures. Because of this, apart from the well known risk factors for osteoporosis, poverty should be taken into account as a possible risk factor for both osteoporosis and fragility fractures, in order to establish sanitary strategies to protect unfavoured postmenopausal women.

Abstract
A large body of epidemiologic data show that diet quality follows a socioeconomic gradient. Whereas higher-quality diets are associated with greater affluence, energy-dense diets that are nutrient-poor are preferentially consumed by persons of lower socioeconomic status (SES) and of more limited economic means. As this review demonstrates, whole grains, lean meats, fish, low-fat dairy products, and fresh vegetables and fruit are more likely to be consumed by groups of higher SES. In contrast, the consumption of refined grains and added fats has been associated with lower SES. Although micronutrient intake and, hence, diet quality are affected by SES, little evidence indicates that SES affects either total energy intakes or the macronutrient composition of the diet. The observed associations between SES variables and diet-quality measures can be explained by a variety of potentially causal mechanisms. The disparity in energy costs ($/MJ) between energy-dense and nutrient-dense foods is one such mechanism; easy physical access to low-cost energy-dense foods is another. If higher SES is a causal determinant of diet quality, then the reported associations between diet quality and better health, found in so many epidemiologic studies, may have been confounded by unobserved indexes of social class. Conversely, if limited economic resources are causally linked to low-quality diets, some current strategies for health promotion, based on recommending high-cost foods to low-income people, may prove to be wholly ineffective. Exploring the possible causal relations between SES and diet quality is the purpose of this review.

Abstract
Background Based on previously reported differences in fracture incidence in the socioeconomic less affluent Oslo East compared to the more privileged West, our aim was to study bone mineral density (BMD) in the same socioeconomic areas in Oslo. We also wanted to study whether possible associations were explained by socio-demographic factors, level of education or lifestyle factors. Methods Distal forearm BMD was measured in random samples of the participants in The Oslo Health Study by single energy x-ray absorptiometry (SXA). 578 men and 702 women born in Norway in the age-groups 40/45, 60 and 75 years were included in the analyses. Socioeconomic regions, based on a social index dividing Oslo in two regions – East and West, were used. Results Age-adjusted mean BMD in women living in the less affluent Eastern region was 0.405 g/cm2 and significantly lower than in West where BMD was 0.419 g/cm2. Similarly, the odds ratio of low BMD (Z-score ≤ -1) was 1.87 (95% CI: 1.22–2.87) in women in Oslo East compared to West. The same tendency, although not statistically significant, was also present in men. Multivariate analysis adjusted for education, marital status, body mass index, physical inactivity, use of alcohol and smoking, and in women also use of post-menopausal hormone therapy and early onset of menopause, did hardly change the association. Additional adjustments for employment status, disability pension and physical activity at work for those below the age of retirement, gave similar results. Conclusion We found differences in BMD in women between different socioeconomic regions in Oslo that correspond to previously found differences in fracture rates. The association in men was not statistically significant. The differences were not explained by socio-demographic factors, level of education or lifestyle factors.

Abstract
INTRODUCTION The impact of socioeconomic status-income and acculturation-on hip fracture is not well understood. We studied 116,919 fractures among 8,144,469 people in California. Greater income and English fluency predict lower fracture incidence. Lower income and immigrant populations are at increased risk for hip fracture and require intervention. Race/ethnicity is a major determinant of hip fracture risk. Although socioeconomic status (e.g., income and acculturation) is often associated with race/ethnicity, its impact on hip fracture incidence is less well understood. METHODS We carried out a retrospective, population-based, study of persons with hip fractures in California, 1996 to 2000, compared to census estimates by zip code. We performed Poisson regression analyses to calculate hip fracture incident rate ratios for gender, age, race/ethnicity, income, language (percent non-English speakers)-a proxy for acculturation-and living in rural areas. RESULTS During the 5-year period, 116,919 fractures occurred among 8,144,469 persons (2.87 fractures/1,000 persons per year). Higher income predicted lower hip fracture incidence. Persons in the highest decile of estimated income had an incident rate ratio (IRR) of 0.79 (95% confidence interval (CI) 0.77 to 0.82) compared with those in the lowest decile. Greater IRR of hip fracture was predicted for persons living in areas with a greater percent of non-English speakers (IRR 1.004, 95% CI 1.003 to 1.005). CONCLUSIONS Low income and language fluency are predictors of greater hip fracture incidence. Although much attention is given to the aging of the "baby boomers", low income and immigrant populations are at increased risk for hip fracture and require intervention.

Abstract
OBJECTIVES The aim of this study was to evaluate a pragmatic screening programme for osteoporosis based on the identification of known risk factors. A secondary aim was to assess the validity of peripheral instantaneous X-ray imager (PIXI) scanning against dual energy X-ray absorptiometry (DEXA) in women identified as having osteopenia. METHODS A cross-sectional two stage screening programme. The study was carried out in 14 practices in Surrey. Women aged 60-80 years of age were screened with a questionnaire. Those identified with one or more risk factors were offered a PIXI scan of the ankle in their own surgery. Those with an intermediate score on PIXI scan were offered a DEXA scan of hip, spine and forearm. RESULTS Four thousand six hundred and forty-six women completed questionnaires, 2688 had a PIXI scan and 553 were found to be at high risk of osteoporosis. Multivariate analysis identified the three most important risk factors associated with increased risk of osteoporotic fracture as age, a previous fracture and the presence of a stooped posture. Hormone replacement therapy (HRT) was shown to be protective. Twenty three percent of women with an intermediate score on PIXI scan were found to have osteoporosis on DEXA scan of hip and spine. CONCLUSIONS PIXI scanning proved acceptable, practicable but only had moderate comparability with DEXA. The findings suggest that patients over the age of 60 years with a history of a fracture or evidence of spinal collapse are likely to have osteoporosis and should be offered screening. HRT past the menopause would seem to confer benefit and the recent reduction in its use may lead to increasing numbers of women suffering osteoporotic fractures.

Abstract
Our objectives were (1) to examine the associations of education and income with bone health in non-Hispanic White, non-Hispanic Black and Mexican-American postmenopausal women, (2) to determine if any observed associations can be explained by behavioral factors such as calcium intake and physical activity and (3) to determine if government food assistance and education are associated with increased calcium intake among low-income women. Cross-sectional data were gathered by the Third National Health and Nutrition Examination Survey, 1988-1994 (NHANES III) using a stratified multistage probability design. Bone health was indicated by total hip bone mineral density (BMD, g/cm2). Multiple linear regression was used to evaluate the associations of education, income and behavioral factors with BMD. There were 2,905 postmenopausal women with acceptable DXA scans and complete relevant data selected from a nationally representative sample of the civilian non-institutionalized population aged 2 months and older. Education and income were positively associated with BMD in Black and White women, respectively, but not in Mexican-American women. When behavioral factors were included in the analyses, associations with education and income were eliminated. Instead, positive associations with estrogen use, calcium intake and physical activity, and a negative association with smoking, were noted in White women. Among low-income women, education was associated with increased calcium intake, while participation in the Food Stamp Program was associated with increased calcium intake in Black women. We conclude that education and/or income are positively associated with BMD among Black and White postmenopausal women, and that efforts to promote bone health among low-income women are warranted.

Abstract
UNLABELLED We studied relationships between social position of the mother in pregnancy and bone mass of the child at age 9.9 years. The tendency for social position to increase bone area and bone mass through a positive influence on height was opposed by a negative effect of social position on weight and fat mass. INTRODUCTION Evidence that social factors influence skeletal growth raises the possibility that bone mass acquisition in childhood is socially determined. MATERIALS AND METHODS To clarify the role of social factors in bone mass acquisition in childhood, we studied relationships between these variables in the Avon Longitudinal Study of Parents and Children (ALSPAC). Measures of the mother's social position during pregnancy were linked to DXA results obtained at age 9.9 years in 6,702 children. Linear regression analyses were carried out after adjusting for age and gender. Because social position may affect height and weight of the child, analyses were repeated after adjusting for these additional variables. RESULTS Measures of social position in pregnancy were unrelated to total body BMC in analyses adjusted for age and gender alone. However, after adjusting for height, which was positively related to social position, a strong negative association was observed between BMC and housing tenure (p < 0.001), maternal education (p < 0.001), paternal education (p < 0.001), and social class (p < 0.001). Similar results were obtained for bone area. After adjusting for weight as well as height, an association between social position and BMC and bone area was no longer observed. Hence, social position seems to exert opposing height- and weight-dependent effects on BMC and bone area in childhood. In further analyses, we found that adjusting for fat mass of the child led to similar results to those obtained with weight. CONCLUSIONS Social position in childhood seems to be positively related to bone mass acquisition in childhood as a consequence of enhanced gain in height (i.e., longitudinal growth). However, this influence is counteracted by the tendency for increased fat deposition in those from a lower social position to increase bone area, presumably reflecting the stimulation of appositional bone growth.

Abstract
PURPOSE OF REVIEW Osteoporosis remains a major public health problem through its association with fragility fractures. Recent data suggest that the annual cost in Europe is 13 billion euros, mainly accounted for by hospitalisation after fracture. Understanding the epidemiology of osteoporosis is an essential step in developing strategies to reduce the burden of osteoporotic fracture in the population. RECENT FINDINGS This article will review recent advances surrounding the epidemiology of osteoporosis, the burden of fracture in children and adults in this country and abroad, morbidity associated with such fractures, associations of disease and medication with fragility fracture, and advances in diagnostic techniques and identification of at-risk groups. SUMMARY The papers studied highlight the wealth of high-quality research in this field, and they help in the visualisation of strategies to identify individuals at high risk of fragility fracture and to quantify fracture risk by measurement of bone density, bone quality, and risk factor algorithms.
