Older men's knowledge of osteoporosis and the prevalence of risk factors

Knowledge, beliefs, and concerns about bone health from a systematic review and metasynthesis of qualitative studies

Background

Patients with low bone density or osteoporosis need information for effective prevention or disease management, respectively. However, patients may not be getting enough information from their primary care providers or other sources. Inadequate disease information leaves patients ill-informed and creates misconceptions and unnecessary concerns about the disease.

Objective

We systematically reviewed and synthesized the available literature to determine patient knowledge, beliefs, and concerns about osteoporosis and identify potential gaps in knowledge.

Methods

A systematic search was conducted for full-text qualitative studies addressing understanding, literacy, and/or perceptions about osteoporosis and its management, using Medline, EMBASE, Web of Science, Cochrane Library, CINAHL, ERIC, PsychINFO, Psyc Behav Sci Collec, and PubMed, from inception through September 2016. Studies were selected by two reviewers, assessed for quality, and themes extracted using the Joanna Briggs Institute data extraction tool. Thematic analysis was used to identify themes and subthemes.

Results

Twenty-five studies with a total of 757 participants (including 105 men) were selected for analysis out of 1031 unique citations. Selected studies were from Australia, Canada, Denmark, Norway, the United Kingdom, and the United States. Four main themes emerged: inadequate knowledge, beliefs and misconceptions, concerns about osteoporosis, and lack of information from health care providers. Participants had inadequate knowledge about osteoporosis and were particularly uninformed about risk factors, causes, treatment, and prevention. Areas of concern for participants included diagnosis, medication side effects, and inadequate information from primary care providers.

Conclusion

Although there was general awareness of osteoporosis, many misconceptions and concerns were evident. Education on bone health needs to reinforce areas of knowledge and address deficits, misconceptions, and concerns.

Adverse effects of media reports on the treatment of osteoporosis

PURPOSE

The review focused on the role that media reporting plays in the level of public awareness about osteoporosis and its influence on osteoporosis treatment decisions.

METHODS

We reviewed the literature on the role of media on three main aspects influencing patient adherence to osteoporosis treatment: the awareness of osteoporosis as a major health problem, the perception of the effectiveness of osteoporosis medications, and the fear of adverse effects with osteoporosis medications.

RESULTS

A review of the literature confirmed what is routinely observed in clinical practice-that media report can strongly influence the level of awareness of osteoporosis and fracture risk. Inadequate and/or incorrect information on osteoporosis in the media are associated with a low level of awareness of the disease. High-risk patients may have a poor understanding of the need for treatment. Alarming information in the media over the last 2 decades regarding effectiveness and safety of long-term osteoporosis treatment is associated with reduction in the use of osteoporosis medications.

CONCLUSIONS

There is a gap between the application of clinical recommendations and patient perceptions of osteoporosis and its treatment. There is a need for better education of patients and practitioners aimed at recognizing the serious consequences of fractures and understanding the expected benefits and potential risks of treatment. Media reports that disseminate evidence-based information on the balance of benefits and risks could help to reduce the osteoporosis treatment gap and mitigate the crisis in osteoporosis care.

Osteoporosis Knowledge and Health Beliefs Among Men in Midlife Years

OBJECTIVE

To examine the role of socioeconomic variables on middle-aged adult men's knowledge and health beliefs about osteoporosis.

METHODS

An anonymous survey used validated scales to assess osteoporosis knowledge and health beliefs in a sample of 262 men aged 36-55 years. Descriptive and group-differences statistics (MANOVA and ANOVA) were used.

RESULTS

Total osteoporosis knowledge was low (mean, 11.1 of 22) and mean scores on perceived susceptibility and seriousness health belief domains were also low: 13.2 and 17.2, respectively out of 30. Multivariate ANOVA revealed that perceived seriousness, barriers to calcium intake, and health motivation varied significantly with level of formal education attained (P < .05). There was no significant difference with income.

CONCLUSIONS AND IMPLICATIONS

Results of this convenience sample of predominantly white men found that level of osteoporosis knowledge and perceived susceptibility were low. Given the increased prevalence of osteoporosis-related fracture in men, methods to increase knowledge and awareness are needed.

Men's knowledge about osteoporosis and its risk factors

INTRODUCTION

Until recently osteoporosis was seen mainly as a woman's problem. However, in the last ten years there has been rising awareness in society that osteoporosis constitutes an inseparable element of getting old for men as well. The aim of the research was to evaluate men's knowledge about osteoporosis and its risk factors contributing to the development of the disease.

MATERIAL AND METHODS

The study included 205 men aged 20-60. The examined men were patients of selected healthcare centres in Lublin Voivodeship. The study was conducted between September 2014 and April 2015. The research was performed by means of the survey method, using a poll technique. Purposive sampling and an original questionnaire were used. Gathered material was subjected to descriptive and statistical analysis. The Mann-Whitney U test and Kruskal-Wallis test were applied. The statistical significance level was set at α = 0.05. IBM SPSS Statistics software was used to perform the statistical analysis.

RESULTS

The respondents' level of knowledge about osteoporosis and its risk factors can be estimated as average. The polled men showed better knowledge on osteoporosis risk factors (M = 59.78) than general osteoporosis knowledge (M = 53.71). Significant differences were found between the respondents' education and their general osteoporosis knowledge as well as between the respondents' living conditions and their knowledge about osteoporosis risk factors.

CONCLUSIONS

Because of the insufficient level of knowledge about osteoporosis and its risk factors in the male population it is advisable to launch prevention programmes aimed at men focusing on this issue.

Second fractures among older adults in the year following hip, shoulder, or wrist fracture

We report on second fracture occurrence in the year following a hip, shoulder or wrist fracture using insurance claims. Among 273,330 people, 4.3 % had a second fracture; risk did not differ by first fracture type. Estimated adjusted second fracture probabilities may facilitate population-based evaluation of secondary fracture prevention strategies.

INTRODUCTION

The purpose of this study was estimate second fracture risk for the older US population in the year following a hip, shoulder, or wrist fracture.

METHODS

Observational cohort study of Medicare fee-for-service beneficiaries with an index hip, shoulder, or wrist fragility fracture in 2009. Time-to-event analyses using Cox proportional hazards models to characterize the relationship between index fracture type (hip, shoulder, wrist) and patient factors (age, gender, and comorbidity) on second fracture risk in the year following the index fracture.

RESULTS

Among 273,330 individuals with fracture, 11,885 (4.3 %) sustained a second hip, shoulder or wrist fracture within one year. Hip fracture was most common, regardless of the index fracture type. Comparing adjusted second fracture risks across index fracture types reveals that the magnitude of second fracture risk within each age-comorbidity group is similar regardless of the index fracture. Men and women face similar risks with frequently overlapping confidence intervals, except among women aged 85 years or older who are at greater risk.

CONCLUSIONS

Regardless of index fracture type, second fractures are common in the year following hip, shoulder or wrist fracture. Secondary fracture prevention strategies that take a population perspective should be informed by these estimates which take competing mortality risks into account.

Comparison of CAROC and FRAX in Fragility Fracture Patients: Agreement, Clinical Utility, and Implications for Clinical Practice

Objective.

To examine the level of agreement between 2 fracture risk assessment tools [Canadian Association of Radiologists and Osteoporosis Canada (CAROC) and Canadian Fracture Risk Assessment (FRAX)] when applied within the context of the Canadian guidelines, in a population of fragility fracture patients.

Methods.

The sample consisted of 135 treatment-naive fragility fracture patients aged 50+ years and screened as part of an osteoporosis (OP) program at an urban hospital. Ten-year probabilities of future major osteoporotic fractures were calculated using the FRAX and CAROC. We also integrated additional qualifiers from the 2010 Canadian guidelines that place hip, spine, and multiple fractures at high risk regardless. A quadratic weighted κ (Kw) and 95% CI were calculated to estimate the chance corrected agreement between the risk assessment tools. Logistic regression was used to evaluate the factors associated with concordance.

Results.

Among patients with fragility fractures, the agreement between CAROC and FRAX was Kw = 0.64 (95% CI 0.58–0.71), with 45 of 135 cases in the cells reflecting disagreement. Younger persons and males were more likely to be found in discordant cells.

Conclusion.

The level of agreement between 2 commonly used fracture risk assessment tools was not as high in the patients with fragility fractures as it was in general community-based samples. Our results suggest discordance is found in less-typical patients with OP who need more consistency in messaging and direction. Users of these fracture risk tools should be aware of the potential for discordance and note differences in risk classifications that may affect treatment decisions.

Osteoporosis and shoulder osteoarthritis: incidence, risk factors, and surgical implications

BACKGROUND

Patients with osteoarthritis undergoing shoulder arthroplasty may suffer from osteoporosis. The purpose of this study was to determine whether computed tomography (CT)-derived Hounsfield unit (HU) measurements correlate with bone mineral density (BMD) and whether these data could predict implant size and fixation choice.

MATERIALS AND METHODS

The study analyzed preoperative dual energy x-ray absorptiometry and shoulder CT scans for 230 patients who underwent total shoulder arthroplasty. Hip BMD and T scores and HU attenuation in the humerus were correlated. HU cutoff values were developed to aid in differentiating patients whose BMD values were within normal reference ranges from patients with osteopenia or osteoporosis. Risk factors associated with low BMD were correlated, and the effect of BMD on humeral stem size, and fixation method was investigated.

RESULTS

Significant correlations between HU and hip BMD and T score were identified (P < .001). HU value ranges were identified that may alert the surgeon of metabolic bone disease. Significant correlation (P < 0.05) was found between low BMD and certain osteoporosis risk factors. Age at time of surgery was a predictor of cemented stem fixation (P = .024). Patients with a lower BMD were statistically more likely to receive a larger-diameter humeral stem (P = .016).

CONCLUSIONS

Orthopedic surgeons may be able to use data obtained from shoulder CT scans to predict the need for larger stem size or cement fixation during shoulder arthroplasty. In combination with the risk factor profile, these data may be useful in predicting the need for an osteoporosis workup and treatment.

Comparison between amputation-induced demineralization and age-related bone loss using digital X-ray radiogrammetry

Digital X-ray radiogrammetry (DXR) is a computer-assisted automatic osteodensitometric tool. This study was performed to compare DXR measurements between bone changes following amputation trauma and age-related bone loss. Thirty-five men, who had undergone finger amputations, received a baseline examination and 2--3 serial measurements. As a second group, 215 males older than 70yr were enrolled. All patients obtained standardized hand radiographs. The following DXR parameters evaluating metacarpals were considered: cortical bone mineral density (DXR-BMD), cortical thickness (DXR-CT), metacarpal index (DXR-MCI), outer bone diameter (width; DXR-W), and inner medullary diameter (DXR-MD). In the amputation group, the DXR parameters showed an accentuated initial decrease between first and second measurements (DRX-BMD--12.7%, DXR-CT--14.2%, DXR-W--8.6%, DXR-MCI--6.1%; p<0.001) followed by a less pronounced reduction between second and third radiographs (DRX-BMD--0.5%, DXR-CT--1.5%, DXR-W--0.1%, DXR-MCI--1.3%). DXR-MD revealed a reduction of--3.6% (p<0.05) between first and second estimates and a non-significant increase (+1.1%) between second and third measurements. When compared with the second and third estimates in the amputation group, men older than 70yr presented lower DXR-BMD, DXR-CT, and DXR-MCI values (p<0.001), but larger metacarpal outer and inner bone diameters (DXR-W and DXR-MD; p<0.001). DXR-MD of the elderly men group was also more extended when compared with the baseline measurements of the amputation cohort (p<0.001). The early accentuated cortical bone loss and particularly the pronounced decrease of the outer bone width seem to be characteristic for amputation-induced osteoporosis, suggesting that this might be a distinct secondary osteoporosis entity. When compared with amputation-associated osteoporosis, where the bone loss occurs to a higher extent in the outer bone diameter than in the medullary cavity, the age-related bone changes lead more to an increase of the medullary diameter than of the outer bone width.

Pattern of use of DXA scans in men: a cross-sectional, population-based study

Osteoporosis in men is underdiagnosed. The use of dual-emission X-ray absorptiometry (DXA) was evaluated in almost 5,000 men aged 60-74 years. DXA was infrequent, despite the presence of multiple risk factors for osteoporosis and a high FRAX score. There is a need for improved targeting of DXA scans for men at high risk.

INTRODUCTION

Clinical and socioeconomic factors associated with bone mass assessment (DXA) in men have seldom been evaluated. This study aimed to evaluate factors associated with the use of DXA in men.

METHODS

Self-report information on prior DXA and osteoporosis risk factors were obtained from the baseline data of a study investigating the health perspectives of men aged 60-75 years. Socioeconomic and comorbidity data were retrieved from national registers. The FRAX algorithm was used to calculate the absolute fracture risk. Regression analysis was used to identify factors significantly associated with previous DXA scan.

RESULTS

Of the 4,696 men returning questionnaires (50% response rate), 2.7% had prior DXA but 48% had at least one osteoporosis risk factor. Previous DXA was associated with oral glucocorticoid treatment, secondary osteoporosis, rheumatoid arthritis, fracture after age 50, falls within the previous year, smoking, and higher age. Twenty-one percent of men with prior DXA and 10% of men without prior DXA had greater than 20% risk of a major osteoporotic fracture within the next 10 years. One third of those with previous DXA had none of the FRAX osteoporosis risk factors. When family history of osteoporosis and falls were included as risk factors, 18% with previous DXA had no clinical risk factors for osteoporosis.

CONCLUSIONS

DXA was infrequent in this group of elderly men, despite the presence of risk factors for osteoporosis. DXA was also used despite a low fracture risk. There is a need for improved targeting of DXA scans for men at high risk.

Living with a `women's disease': risk appraisal and management among men with osteoporosis

BACKGROUND: There is clear evidence that men suffer from osteoporosis (OP) in increasing numbers, but that men commonly remain underdiagnosed, undertreated and experience poorer outcomes than do women. The widespread sociocultural association of OP with postmenopausal women reflects their greater risk for developing the disorder, but the sexing of OP as a women's disease disadvantages at-risk men. METHODS: This paper reports on qualitative data gathered from 23 community-residing men who have an OP diagnosis. RESULTS: Interviews with men reveal that the sexing of OP as a female disease may affect men's risk appraisal. Men clearly associate OP risk factors with women and accordingly may feel protected from the disorder. Subsequent to diagnosis, men's OP-related risk management strategies reveal that men's gender identity constrains their ability to enact risk-reducing behavior. CONCLUSIONS: Men may internalize the association of OP with women and incorporate it into a sense of perceived invulnerability to the condition, which, in turn, contributes to delayed diagnosis and treatment. Limited male-specific treatment and support options as well as social expectations of male gender performance play roles in men's health behavior.
