An association between socioeconomic, health and health behavioural indicators and fractures in young adult males

Alcohol and drug use in adults younger than 60 years with hip fracture - A comparison of validated instruments and the clinical eye: A prospective multicenter cohort study of 218 patients

BACKGROUND

It is a common preconception that young individuals sustaining hip fractures have alcohol and/or drug use disorder. It is important to evaluate the actual use to avoid complications and plan the rehabilitation.

AIM

The primary objective was to assess alcohol and drug consumption in hip fracture patients <60 years using the validated Alcohol Use Disorders Identification Test (AUDIT) and Drug Use Disorders Identification Test (DUDIT) scores. We secondarily investigated the agreement between the instruments and the physicians' clinical evaluation of usage.

MATERIAL AND METHODS

This is a sub-study of 91 women and 127 men from a multicenter cohort study of patients with an acute hip fracture treated at four hospitals in Denmark and Sweden. AUDIT and DUDIT forms were completed by the patients. In addition, the researchers made an evaluation of the patients' alcohol/drug use based on direct patient contact and information on previous alcohol/drug use from medical charts. AUDIT ranges 0-40 with 6 (women) and 8 (men) as the cut-off for hazardous use. DUDIT ranges 0-44 with cut-offs of 2 and 6 indicating drug-related problems.

RESULTS

According to the AUDIT, 29 % of the patients had a hazardous alcohol use (25 % women, 31 % men), whilst the clinical evaluation identified 26 % (24 % women, 28 % men). However, there was a low agreement between "the clinical eye" and AUDIT, as the clinical evaluation only correctly identified 35 of 56 individuals with AUDIT-scores indicating hazardous alcohol use. DUDIT equaled drug related problems in 8 % (5 % women, 10 % men), the clinical evaluation depicted 8 % with drug related problems (4 % women, 10 % men). The agreement was low between "the clinical eye" and DUDIT; only 7 of 15 with DUDIT-scores indicating drug related problems were correctly identified.

CONCLUSION

Hazardous alcohol consumption is more common in non-elderly hip fracture patients than in the general population. Considering both self-reported alcohol use and clinical evaluation, women have almost as high rate as men. DUDIT indicated drug related problems to be slightly more common than in the population. Still, a majority did not exhibit troublesome use of neither alcohol nor drugs. The two screening methods do not identify the same individuals, and further investigation in clinical practice is needed.

Influence of Social Deprivation on Patient-Reported Outcomes in Foot and Ankle Patients

Background

The impact of social health on patient-reported outcomes (PROs) is gaining increasing attention within the orthopaedic community. Few studies have explored any relationship between social deprivation levels and PROs in orthopaedic foot and ankle patients.

Methods

We retrospectively identified patients who presented to an orthopaedic foot and ankle clinic for new evaluation. Patients completed PROs including PROMIS physical function (PF), PROMIS pain interference (PI), and the Foot and Ankle Ability Measure (FAAM). Social deprivation was measured using the Area Deprivation Index (ADI), a metric that incorporates various domains of poverty, education, housing, and employment. The ADI score quantifies the degree of social deprivation based on the 9-digit home zip code but is not a specific measure to an individual patient. Briefly, a lower ADI indicates less deprivation whereas a higher score denotes greater deprivation. Patient characteristics and outcomes were summarized and stratified by the nationally defined median ADI. Multivariable linear regression models assessed the relationships between PROs and continuous ADI controlling for demographics (age, sex, race/ethnicity, marital status, and employment status).

Results

Our cohort consisted of 1565 patients with PRO and appropriate zip code data. Patients in the most-deprived median ADI split had more pain (median PROMIS-PI 62.7 vs 61.2, P = .001) and less function (median PROMIS-PF 37.1 vs 38.6, P = .021) compared with the least-deprived median ADI split. The clinical significance of these findings is unclear, though, given the minimal differences between groups for PROMIS measures. There was no relationship between ADI and FAAM scores.

Conclusion

More socially deprived patients presented to the clinic with marginally less function and greater pain. Although statistically significant, the clinical significance of these relationships is unclear and merits further exploration. We plan to continue to study the connection between social deprivation and patient outcomes in specific clinical conditions as well as before/after surgical interventions.

Physical Activity and Psychosocial Factors Associated With Risk of Future Fractures in Middle-Aged Men and Women

Identification of risk factors for fractures is important for improving public health. We aimed to identify which factors related to physical activity and psychosocial situation were associated with incident fractures among 30,446 middle-aged women and men, followed from 1991-1996 to 2016, in a prospective population-based cohort study. The association between the baseline variables and first incident fracture was assessed by Cox regression models, and significant risk factors were summed into fracture risk scores. Any first incident fracture affecting spine, thoracic cage, arms, shoulders, hands, pelvis, hips, or legs was obtained from the National Patient Register, using the unique personal identity number of each citizen. A total of 8240 subjects (27%) had at least one fracture during the follow-up of median 20.7 years. Age, female sex, body mass index, previous fracture, reported family history of fracture >50 years (all p < .001), low leisure-time physical activity (p = .018), heavy work (p = .024), living alone (p = .002), smoking (p < .001), and no or high alcohol consumption (p = .005) were factors independently associated with incident fracture. The fracture risk score (0-9 points) was strongly associated with incident fracture (p for trend <.001). Among men without risk factors, the incidence rate was 5.3/1000 person-years compared with 23.2 in men with six or more risk factors (hazard ratio [HR] = 5.5; 95% confidence interval [CI] 3.7-8.2). Among women with no risk factors, the incidence rate was 10.7 compared with 28.4 in women with six or more risk factors (HR = 3.1; 95% CI 2.4-4.0). Even moderate levels of leisure-time physical activity in middle age are associated with lower risk of future fractures. In contrast, heavy work, living alone, smoking, and no or high alcohol consumption increase the risk of fracture. Our results emphasize the importance of these factors in public health initiatives for fracture prevention. © 2021 The Authors.

The Utility of Skeletal and Surgical Features for the Personal Identification Process: A Pilot Study

This pilot study provides a conceptual framework for the application of the anthropological analysis of skeletal features and surgical interventions for the purpose of identification in cases of unknown deceased individuals with unavailable fingerprint, genetic or odontological antemortem data. The study sample includes 276 individuals with known demographic and clinical information from the Italian CAL Milano Cemetery Skeletal Collection. In the sample, 124 (45%) individuals showed one or more skeletal features that may be potentially individualizing. Of these, 79% showed two and more features, which occurred in a multitude of different combinations. Skeletal findings may provide useful postmortem information that can be compared with antemortem witness statements and clinical imaging. However, more research into the utility of dry bone findings and the availability of comparative material, including imaging, and epidemiological data needs to be undertaken before skeletal features can be implemented into identification protocols and databases.

Fracture risk of young adults receiving proton-pump inhibitors and H2-receptor antagonists

INTRODUCTION

Proton-pump inhibitors (PPI) and histamine (type 2) receptor antagonists (H2RA) have the potential to interfere with calcium metabolism. Several authors have evaluated the effect of these medications on fracture incidence in older adults. A recent large epidemiologic study demonstrated a higher risk of fractures in young adults receiving PPI.

AIM

To evaluate the effect of PPI and H2RA use on fracture incidence in a large retrospective cohort of military recruits representative of general population of young adults.

METHODS

A retrospective cohort of 254 265 male and 234 670 female non-combat military conscripts ages 18-25. Subjects were divided into three groups by PPI use (no PPI use, 1-100 tablets and more than 100 tablets) and two groups by H2RA use (no H2RA use, any H2RA use). Multivariate logistic regression was used to adjust fracture risk for age, BMI, education level, socio-economic level, ethnic origin, occupation and duration of follow-up in months.

MAIN OUTCOME MEASURES

At least one fracture during the study period.

RESULTS

Use of PPI and H2RA was not associated with an increased risk of fractures. In men, the predictors of an increased fracture risk were higher BMI (OR = 1.007, P < 0.001), origin from a developing country (OR = 1.15, P < 0.001) and service as a driver (OR = 1.11, P < 0.001). Higher education, higher socioeconomic status and service as an officer or as an administrative worker had a protective effect on fracture incidence. In women, fractures were associated with higher BMI (OR = 1.035, P < 0.001). Origin from a developed country, as well as service as an officer or an administrative worker was associated with lower fracture risk.

CONCLUSIONS

There was no association between the use of PPI or H2-antagonists and fracture incidence in this retrospective cohort of healthy young military recruits.

Lower risk of fractures under methylphenidate treatment for ADHD: A dose-response effect

Methylphenidate (MP), a widely used and abused stimulant medication for ADHD, negatively affects bone mass. However, previous epidemiological studies demonstrated that MP is not associated with increased incidence of fractures in children, and may even have a protective effect due to behavior modification. This study aimed to investigate the association between MP and fracture risk in a retrospective cohort of healthy military recruits, aged 18-25, with at least 1 year of service between 2008 and 2017. Subjects were divided into five groups: subjects without ADHD; untreated subjects with ADHD; and subjects with ADHD and prescriptions of 1-90, 91-180, or 181+ tablets during the study period. The primary outcome was at least one fracture diagnosis during the study. Among 682,110 subjects (409,175 men [60%]), 50,999 (7.5%) had fractures. MP was used by 1,681 (0.4%) men and 2.828 (1%) women. The fracture rates in the no ADHD, untreated ADHD, ADHD 0-90, ADHD 91-180, and ADHD 181+ groups were 10.4%, 16.4%, 8.7%, 4.8% and 5.8% in men, and 3.6%, 7.1%, 4.6%, 4.4% and 3% in women, respectively. Multivariate regression analysis confirmed an inverse dose-response association between MP and fractures in men (p < 0.001). In women, untreated ADHD was associated with a significantly higher fracture risk, compared to healthy controls (OR = 1.82, p < 0.001). The study confirms previous literature and demonstrates an inverse dose-response association between MP and fracture risk in men. © 2018 Orthopaedic Research Society.

Women with severe obesity and relatively low bone mineral density have increased fracture risk

Among women with obesity, those with the lowest bone density have the highest fracture risk. The types of fractures include any fracture, fragility-type fractures (vertebra, hip, upper arm, forearm, and lower leg), hand and foot fractures, osteoporotic, and other fracture types.

INTRODUCTION

Recent reports have contradicted the traditional view that obesity is protective against fracture. In this study, we have evaluated the relationship between fracture history and bone mineral density (BMD) in subjects with obesity.

METHODS

Fracture risk was assessed in 400 obese women in relation to body mass index (BMI), BMD, and clinical and laboratory variables.

RESULTS

Subjects (mean age, 43.8 years; SD, 11.1 years) had a mean BMI of 46.0 kg/m(2) (SD, 7.4 kg/m(2)). There were a total of 178 self-reported fractures in 87 individuals (21.8% of subjects); fragility-type fractures (hip, vertebra, proximal humerus, distal forearm, and ankle/lower leg) were present in 58 (14.5%). There were higher proportions of women in the lowest femoral neck BMD quintile who had any fracture history (41.3 vs. 17.2%, p < 0.0001), any fragility-type fractures (26.7 vs. 11.7%, p = 0.0009), hand and foot fractures (16.0 vs. 5.5%, p = 0.002), other fracture types (5.3 vs. 1.2%, p = 0.02), and osteoporotic fractures (8.0 vs. 1.2%, p < 0.0001) compared to the remaining population. The odds ratio for any fracture was 0.63 (95% CI, 0.49-0.89; p = 0.0003) per SD increase in BMD and was 4.3 (95% CI, 1.9-9.4; p = 0.003) in the lowest BMD quintile compared to the highest quintile. No clinical or biochemical predictors of fracture risk were identified apart from BMD.

CONCLUSIONS

Women with obesity who have the lowest BMD values, despite these being almost normal, have an elevated risk of fracture compared to those with higher BMD.

The relationship between social deprivation and the incidence of adult fractures

BACKGROUND

Social deprivation is associated with many diseases. To our knowledge, there has been no previous investigation of its role in the epidemiology and incidence of fractures in adults.

METHODS

We analyzed 6872 consecutive fractures in patients fifteen years of age or older over a one-year period. Social deprivation was analyzed using the Carstairs score, which is derived from patients' postal codes and accurately defines social deprivation in our population.

RESULTS

Social deprivation is associated with an increasing fracture incidence. The effect is not linear, and the most deprived 10% of society are affected. The odds ratios of the most deprived 10% of society having an increased incidence of fractures are 3.7 in males and 3.1 in females.

CONCLUSIONS

Social deprivation is associated with a significant increase in the incidence of fractures in the most deprived 10% of the population. Most fracture types are affected.

The relationship of fall-related fractures to social deprivation

The relationship between fall-related fractures and social deprivation was studied in 3,843 patients. The incidence of fractures correlated with deprivation in all age groups although the spectrum of fractures was not affected by deprivation. The average age and the prevalence of hip fractures decreased with increasing deprivation.

INTRODUCTION

This study examines the relationship between social deprivation and fall-related fractures. Social deprivation has been shown to be a predisposing factor in a number of diseases. There is evidence that it is implicated in fractures in children and young adults, but the evidence that it is associated with fragility fractures in older adults is weak. As fragility fractures are becoming progressively more common and increasingly expensive to treat, the association between social deprivation and fractures is important to define.

METHODS

All out-patient and in-patient fractures presenting to the Royal Infirmary of Edinburgh over a 1-year period were prospectively recorded. The fractures caused by falls from a standing height were analysed in all patients of at least 15 years of age. Social deprivation was assessed using the Carstairs score and social deprivation deciles, and the 2001 census was used to calculate fracture incidence. The data were used to analyse the relationship between social deprivation and fall-related fractures in all age groups.

RESULTS

The incidence of fall-related fractures correlated with social deprivation in all age groups including fragility fractures in the elderly. The overall spectrum of fractures was not affected by social deprivation although the prevalence of proximal femoral fractures decreased with increasing deprivation. The average age of patients with fall-related fractures also decreased with increasing social deprivation as did the requirement for in-patient treatment.

CONCLUSIONS

This is the first study to show the relationship between fall-related fractures and social deprivation in older patients. We believe that the decreased incidence of proximal femoral fractures, and the lower average age of patients with fall-related fractures, in the socially deprived relates to the relative life expectancies in the different deprivation deciles.

Possible factors for ankle fractures

Background/Aim. Classification of ankle fractures is commonly used for selecting an appropriate treatment and prognosing an outcome of definite management. One of the most used classifications is the Danis-Weber classification. To the best of our knowledge, in the available literature, there are no parameters affecting specific types of ankle fractures according to the Danis-Weber classification. The aim of this study was to analyze the correlation of the following parameters: age, body weight, body mass index (BMI), height, osteoporosis, osteopenia and physical exercises with specific types of ankle fractures using the Danis-Weber classification. Methods. A total of 85 patients grouped by the Danis-Weber classification fracture types were analyzed and the significance of certain parameters for specific types of ankle fractures was established. Results. The proportion of females was significantly higher (p < 0.001) with a significantly higher age (59.9 years, SD ? 14.2) in relation to males (45.1 years, SD ? 12.8) (p < 0.0001). Type A fracture was most frequent in the younger patients (34.2 years, SD ? 8.6), and those with increased physical exercises (p = 0.020). In type B fracture, the risk factor was osteoporosis (p = 0.0180), while in type C fracture, body weight (p = 0.017) and osteoporosis (p = 0.004) were significant parameters. Conclusion. Statistical analysis using the Danis-Weber classification reveals that there are certain parameters suggesting significant risk factors for specific types of ankle fractures.

The impact of obesity on the musculoskeletal system

Obesity is associated with a range of disabling musculoskeletal conditions in adults. As the prevalence of obesity increases, the societal burden of these chronic musculoskeletal conditions, in terms of disability, health-related quality of life, and health-care costs, also increases. Research exploring the nature and strength of the associations between obesity and musculoskeletal conditions is accumulating, providing a better understanding of underlying mechanisms. Weight reduction is important in ameliorating some of the manifestations of musculoskeletal disease and improving function.
