Hip osteoarthritis signs and symptoms are associated with increased fall risk among community-dwelling older adults with chronic low back pain: a prospective study

Factors Associated With Falls Among Community-Dwelling Older Adults With Osteoarthritis: A Sex Subgroup Analysis

Osteoarthritis elevates the risk of falling among older adults due to joint pain and stiffness, especially among women, yet sex influences in these associations remain understudied. This study investigated factors associated with falls by sex. A sample of community-dwelling older adults with osteoarthritis from the 2016 Health and Retirement Study (2624 females; 1271 males) was analyzed using survey-weighted logistic regression, controlling for sociodemographic characteristics such as geographic residence and health-related issues. For women with osteoarthritis, higher risk of falling was associated with being White compared to Black, living in rural areas compared to urban areas, in addition to opioid use. Among men with osteoarthritis, having heart problems and better distal vision increased the risk of falling. Sex-specific fall prevention strategies, such as rural programs, opioid education for women, and increasing awareness and fall education for men with heart problems, are encouraged to promote active living among older adults with osteoarthritis.

Pain Medication Frequency and Fall Risk Among Community-Dwelling Older Adults With Arthritis

Pain medication is commonly used among older adults with arthritis, elevating the risk of falling. We examined fall risks related to the frequency of taking pain medication among community-dwelling older adults with arthritis by analyzing a nationally representative sample of community-dwelling Medicare beneficiaries aged >65 with self-reported arthritis (n = 4,225) in the 2015 National Health and Aging Trends Study. The survey-weighted logistic regression revealed that after controlling for confounding factors, recent falls were associated with taking pain medication daily compared to never (OR = 1.45, 95% CI: 1.06, 1.96). The other categories of medication frequency, compared to never, were not associated with fall risk. Findings suggest that more prudent use of pain medication should be stressed by health care providers for older adults with arthritis to help reduce the risk of falls and fall injuries. Nonpharmacological pain management is encouraged to support active living among older adults with arthritis.

The genetic causal association between arthritis and low back pain

BACKGROUND

Arthritis and low back pain (LBP) are prevalent musculoskeletal conditions with a perceived association. Previous observational studies have suggested a possible link between arthritis and LBP, but causality has not been firmly established.

METHODS

The analysis involved data from a meta-analysis of genome-wide association studies sourced from the UK Biobank Genetics resources on rheumatoid arthritis (RA), osteoarthritis (OA) at any site, knee osteoarthritis (KOA), hip osteoarthritis (HOA), and LBP. Two-sample Mendelian randomization analysis was utilized to evaluate the causal link between arthritis and LBP. The primary method employed was inverse-variance weighting (IVW), with additional techniques such as MR-Egger, weighted median, Cochran Q statistic, and leave-one-out analysis used to identify heterogeneity and pleiotropy.

RESULTS

Genetically determined RA exhibited a causal impact on LBP (Weighted median: odds ratio [OR] = 1.094, 95% confidence interval [CI] 1.002-1.195, p = 0.043). Furthermore, OA at any site and KOA showed causal associations with LBP (Inverse variance weighted: OR = 1.089, 95% CI 1.011-1.173, p = 0.026) and (OR = 1.0004, 95% CI 1.000-1.008, p = 0.019), respectively. Additionally, HOA was also linked causally with an elevated risk of developing LBP (Weighted median: OR = 1.002, 95% CI 1.000-1.004, p = 0.049; Inverse variance weighted: OR = 1.002, 95% CI 1.001-1.004, p = 0.003).

CONCLUSIONS

This study offers genetic evidence supporting the causal relationship between RA, OA at any site, KOA, HOA and the increased risk of LBP, especially highlighting the significant impact of HOA.

Associations of Co-Occurring Chronic Conditions With Use of Rehabilitation Services in Older Adults With Back Pain: A Population-Based Cohort Study

OBJECTIVE

The objective was to examine the associations of number and type of chronic conditions with the use of rehabilitation services among older adults with bothersome back pain.

METHODS

We conducted a cohort study using the National Health and Aging Trends Study, a longitudinal survey of Medicare beneficiaries ≥65 years. We included community-dwelling older adults with bothersome back pain in 2015. We assessed 12 self-reported chronic conditions, including arthritis, depression, and anxiety. We used 2016 data to ascertain self-reported use of any rehabilitation services in the prior year. We used weighted, logistic regression to examine the association of conditions with rehabilitation use.

RESULTS

The sample size was 2443. A majority were age ≥75 years (59%); female (62%); and White, non-Hispanic (71%). The median number of chronic conditions was 3 (interquartile range, 2-4). Arthritis was the most common chronic condition (73%); 14% had anxiety; and 16% had depression. For every additional chronic condition, adjusted odds of any rehabilitation use increased 21% (Odds Ratio = 1.21, 95% CI = 1.11-1.31). Those with ≥4 chronic conditions had 2.13 times higher odds (95% CI = 1.36-3.34) of any rehabilitation use in the next year versus those with 0-1 condition. Participants with arthritis had 1.96 times higher odds (95% CI = 1.41-2.72) of any rehabilitation use versus those without arthritis. Anxiety and depression were not significantly associated with rehabilitation use.

CONCLUSIONS

Among older adults with back pain, a greater number of chronic conditions and arthritis were associated with higher use of rehabilitation services. Those with anxiety or depression had no difference in their use of rehabilitation care versus those without these conditions.

IMPACT

This pattern suggests appropriate use of rehabilitation for patients with back pain and multiple chronic conditions based on greater need, but there may be potential underuse for those with back pain and psychological conditions.

Causal associations between frailty and low back pain: a bidirectional two-sample mendelian randomization study

BACKGROUND

Previous observational studies have revealed a potentially robust bidirectional relationship between frailty and low back pain (LBP). However, the precise causal relationship remains unclear.

METHODS

To examine the potential causal association between frailty and LBP, we conducted bidirectional two-sample Mendelian randomization analysis (MR) study. Genetic data on frailty index (FI) and LBP were acquired from publicly available genome-wide association studies (GWAS). Various MR methodologies were utilized, such as inverse variance weighting (IVW), weighted median, and MR-Egger, to evaluate causality. Additionally, sensitivity analyses were conducted to evaluate the robustness of the findings.

RESULTS

Genetically predicted higher FI (IVW, odds ratio [OR] = 1.66, 95% CI 1.17-2.36, p = 4.92E-03) was associated with a higher risk of LBP. As for the reverse direction, genetic liability to LBP showed consistent associations with a higher FI (IVW, OR = 1.13, 95% CI 1.07-1.19, p = 2.67E-05). The outcomes from various MR techniques and sensitivity analyses indicate the robustness of our findings.

CONCLUSION

Our research findings provide additional evidence bolstering the bidirectional causal relationship between frailty and LBP.

Total hip arthroplasty for adult patients with hip arthritis in Jordan: clinical profiles and patient characteristics

PURPOSE

Total Hip Arthroplasty (THA) is one of the most commonly performed orthopaedic surgeries, with hip arthritis being the main indication. This procedure is usually performed when other non-surgical methods fail to relieve patients' hip pain and improve their quality of life. However, limited information exists to identify and compare the demographics and clinical characteristics of patients undergoing this procedure in Jordan. This study aims to identify these demographic and clinical characteristics and compare the findings in terms of gender differences.

METHODOLOGY

This is a retrospective study that analysed the hospital records of 650 patients undergoing THA in tertiary referral hospital in Jordan over a four-year period from January 2019 to December 2022. The collected data were classified into three categories: demographic characteristics, perioperative variables, and patients' related health profiles. IBM's Statistical Package for the Social Sciences (SPSS) version 23 software (IBM, USA) and descriptive analysis were used for data analysis.

RESULTS

Two-thirds of the sample studied were female (63.4%). In terms of bleeding profiles, the mean intraoperative blood loss was 542 millilitres. The major indication for THA was degenerative hip arthritis (50.5%), followed by hip dysplasia (40.3%).. Comparing the findings of the two gender groups, females were more likely to have degenerative and dysplastic hip arthritis (221 and 157, p = 0.04 and p = 0.1, respectively) when compared to males. Although males were more likely to lose more blood during the surgery (557 ml vs. 533 ml, p = 0.33, females needed more blood transfusions both during (21 vs. 6 patients, p = 0.12) and after the surgery (57 vs. 16 patients, p = 0.006). Furthermore, females were more likely to have comorbidities such hypertension (293 vs. 179 patients, p = 0.20), and hypothyroidism (313 vs 187, p = 0.36), and diabetes (85 vs. 38 patients, p = 0.15), among many other health conditions. However, in the study sample, male smokers outnumbered female smokers (132 vs. 63).

CONCLUSION

Gender highly impacted the immediate surgical outcomes of patients who underwent THA. Females were more likely to need blood transfusions both during and after the surgery and had lower post-operative haemoglobin readings. In addition, females had more comorbidities and degenerative hip osteoarthritis. We believe that raising awareness about comorbidity management, preoperative smoking cessation, and perioperative blood transfusion management can improve medical and surgical outcomes.

A Clinical Measure of Trunk Neuromuscular Function Predicts Falling in Older Adults With Chronic Low Back Pain

BACKGROUND AND PURPOSE

Older adults with low back pain (LBP) are at risk for falling, but condition-specific mechanisms are unknown. Trunk neuromuscular function is critical for maintaining balance during mobility tasks and is often impaired in older adults with LBP. The purpose of this study was to assess whether aberrant lumbopelvic movements (or aberrant movements), a clinical index of trunk neuromuscular function, were associated with increased fall risk among older adults with chronic LBP over a 12-month follow-up period.

METHODS

This study analyzed data from a prospective cohort study of 250 community-dwelling older adults with chronic LBP. Participants were screened for 4 aberrant movements during 3 trials of forward flexion from a standing position: instability catch, painful arc, altered lumbopelvic rhythm, and Gower's sign. Aberrant movements were totaled to yield a summary score (ie, 0-4). Prospective falls were monitored via monthly fall calendars for 12 months. A generalized linear model with Poisson distribution and log link function was used to evaluate the association between aberrant movements and prospective fall risk. Age, sex, body mass index, LBP intensity, dynamic balance performance, prior falls, anxiolytic medication usage, and hip osteoarthritis characteristics were included as covariates in the model.

RESULTS

Baseline aberrant movements were independently associated with greater fall risk (risk ratio = 1.249, 95% CI = 1.047-1.491, P = .014); each 1-unit increase in aberrant movement score imparted a 24.9% increase in the risk of falling.

CONCLUSIONS

Aberrant movements increased the risk of falling among older adults with chronic LBP over a 1-year span.

Fall risk in patient with dysplastic hip osteoarthritis

PURPOSE

Patients with dysplastic hip osteo arthritis (DHOA) often have a spinopelvic imbalance, and they are more likely to experience falls. This study aimed to evaluate the risk factors for falls in patients with DHOA, including spinopelvic parameters.

METHODS

In this cross-sectional study, a total of 103 patients with DHOA were included from 2019 to 2021. Fall risk was evaluated using the Fall Risk Index 5 items version (FRI-5). Demographics, functional outcomes, and spinopelvic parameters were compared between the high-risk group (FRI-5 ≥ 6) and the low-risk group (FRI-5 < 6). Multivariate analysis was performed using factors with significant differences in univariate analysis.

RESULTS

High-risk and low-risk groups comprised 54 and 49 patients, respectively. Females were significantly more common in the high-risk group than in the low-risk group. The Harris Hip Score was significantly lower in the high-risk group than in the low-risk group (p = 0.02). Pelvic incidence, tilt, and obliquity were significantly higher in the high-risk group than in the low-risk group (p < 0.01). In multivariate analysis, female sex (odds ratio [OR]: 3.76, 95% confidence interval [CI]: 1.11-12.64, p = 0.03), pelvic obliquity (OR: 1.36, 95% CI: 1.09-1.71, p < 0.01), and Harris hip score (OR: 0.96, 95% CI: 0.93-0.99, p = 0.02) were identified as risk factors.

CONCLUSION

Female sex, pelvic obliquity, and low Harris hip score were associated with an increased risk of falls among patients with DHOA.

Association between changes in depressive symptoms and falls: The China health and retirement longitudinal study (CHARLS)

PURPOSE

This study aimed to investigate the impact of depressive symptoms and changes in depressive status on falls among middle-aged and older population in China.

METHODS

We used two waves of interview data (time 1 [T1] and time 2 [T2], 2 years from T1) from a nationally representative sample of the China Health and Retirement Longitudinal Study (CHARLS), which included a total of 14,356 participants (male 6859; mean age: 59.5 ± 9.3 years). Depressive symptoms were assessed using the 10-item short form of the Center for Epidemiologic Studies Depression Scale (CES-D-10). Participants were categorized into four groups based on changes in their CES-D-10 scores over a 2-year follow-up period. Self-reported falls were evaluated, and logistic regression models and restricted cubic splines (RCS) were employed to examine the relationship between depressive symptoms and fallen.

RESULTS

Participants who had experienced falls had higher CES-D-10 scores and were more likely to have depressive symptoms. Depressive symptoms at T1 were significantly associated with falls during the follow-up period. After adjusting for covariables, increasing CES-D-10 scores were associated with higher adjusted odds ratios (ORs) for falling prevalence: 1.230 (95 % CI, 1.041-1.453), 1.579 (95 % CI, 1.331-1.873), 1.745 (95 % CI, 1.472-2.070), and 2.366 (95 % CI, 1.972-2.838). Participants who experienced depressive symptoms at either T1 or T2, as well as those with persistent depressive symptoms from T1 to T2, were both at higher risk for future falls. The worsening of depressive symptoms significantly increased the likelihood of falls.

CONCLUSION

This study revealed a significant association between depressive symptoms and changes in depressive status with subsequent falls in older adults. The heightened fall risk among individuals with depressive symptoms underscores the importance of addressing mental health as an integral part of comprehensive fall prevention strategies.

Multimorbidity in osteoarthritis and pleiotropic effects of slow-acting symptomatic drugs. Resolution of the multidisciplinary International Expert Council

   In recent decades, the prevalence of osteoarthritis (OA), one of the most disabling diseases, has increased worldwide, which imposes a significant burden on society. At the international multidisciplinary meeting, experts of various specialties (rheumatology, neurology, endocrinology, geriatrics, rehabilitation, traumatology and orthopedics) from Russia, Uzbekistan, and Kazakhstan discussed the importance of an individualized approach to the treatment of patients with OA, taking into account comorbidities, identified the most important and common clinical phenotypes of the disease, discussed known symptom- and structure-modifying effects of a combination of glucosamine and chondroitin sulfate, and new data on additional (pleiotropic) effects of these drugs that may have a positive impact on the course of comorbid diseases and conditions. The resolution of the Expert Council summarizes the results of the discussion and focuses on issues that are important for the further development of therapeutic approaches and recommendations for the management of such patients.

The prevalence of osteoarthritis and its association with geriatric syndromes in people over 65: data from the Russian epidemiological study EVKALIPT

Background. Osteoarthritis (OA) in elderly and senile patients is not only common, but also one of the main diseases affecting the duration of active life, its quality, the appearance of addictions and loss of autonomy. Data on the relationship between OA and geriatric syndromes (GS) in our country are extremely scarce. Aim. To estimate the prevalence of OA and to analyze its associations with HS in persons aged 65 years. Materials and methods. The study included 4308 people (30% of men) aged 65 to 107 years, living in 11 regions of Russia. The patients were divided into 2 groups: with OA (n=2464) and without OA (n=1821). All patients underwent a comprehensive geriatric assessment. Results. The prevalence of OA was 57.6%. With age, the frequency of OA increased significantly. According to the results of a comprehensive geriatric assessment, patients with OA had lower walking speed, the sum of points on the Bartel, Lawton scales and a short battery of physical functioning tests and higher the sum of points on the geriatric scale of depression and the age is not a hindrance scale. Patients with OA rated the quality of life and health status lower and higher the intensity of pain syndrome. Patients with OA were more likely to use any assistive device, with the exception of a wheelchair. In patients with OA, the most common HS were chronic pain syndrome (92%), senile asthenia syndrome (64%), basic (66%) and instrumental (56%) dependence in everyday life, cognitive impairment (62%), probable depression (51%) and urinary incontinence (50%). Univariate regression analysis showed that OA is associated with a 1.23.0-fold increase in the risk of a number of GS and a 28% decrease in the risk of malnutrition. Conclusion. OA is widespread in the elderly population. The presence of OA is associated with a number of GS associated with loss of autonomy.

Musculoskeletal pain in Parkinson's disease: a narrative review

The prevalence of musculoskeletal (MSK) pain in people with Parkinson's disease (PD) is higher than that of age-matched controls. In this review, we outline what is known about MSK pain in PD, focusing on the neck, shoulder, knee, hip and low back. We also compare what is known about MSK pain in PD to what is known in older adults without PD. Finally, we outline areas of for future research related to MSK pain in people with PD.

Multi-Dimensional Impact of Chronic Low Back Pain among Underserved African American and Latino Older Adults

Chronic low back pain is one of the most common, poorly understood, and potentially disabling chronic pain conditions from which older adults suffer. The existing low back pain research has relied almost exclusively on White/Caucasian participant samples. This study examines the correlates of chronic low back pain among a sample of underserved urban African American and Latino older adults. Controlling for age, gender, race/ethnicity, education, living arrangement, and number of major chronic conditions, associations between low back pain and the following outcome variables are examined: (1) healthcare utilization, (2) health-related quality of life (HR-QoL) and self-rated quality of health; and (3) physical and mental health outcomes.

METHODS

We recruited nine hundred and five (905) African American and Latino older adults from the South Los Angeles community using convenience and snowball sampling. In addition to standard items that measure demographic variables, our survey included validated instruments to document HR-QoL health status, the Short-Form McGill Pain Questionnaire-2, Geriatric Depression Scale, sleep disorder, and healthcare access. Data analysis includes bivariate and 17 independent multivariate models.

RESULTS

Almost 55% and 48% of the Latino and African American older adults who participated in our study reported chronic low back pain. Our data revealed that having low back pain was associated with three categories of outcomes including: (1) a higher level of healthcare utilization measured by (i) physician visits, (ii) emergency department visits, (iii) number of Rx used, (iv) a higher level of medication complexity, (v) a lower level of adherence to medication regimens, and (vi) a lower level of satisfaction with medical care; (2) a lower level of HR-QoL and self-assessment of health measured by (i) physical health QoL, (ii) mental health QoL, and (iii) a lower level of self-rated health; and (3) worse physical and mental health outcomes measured by (i) a higher number of depressive symptoms, (ii) a higher level of pain, (iii) falls, (iv) sleep disorders, (v) and being overweight/obese.

DISCUSSION

Low back pain remains a public health concern and significantly impacts the quality of life, health care utilization, and health outcomes of underserved minority older adults. Multi-faceted and culturally sensitive interventional studies are needed to ensure the timely diagnosis and treatment of low back pain among underserved minority older adults. Many barriers and challenges that affect underserved African American and Latino older adults with low back pain simply cannot be addressed in over-crowded EDs. Our study contributes to and raises the awareness of healthcare providers and health policymakers on the necessity for prevention, early diagnosis, proper medical management, and rehabilitation policies to minimize the burdens associated with chronic low back pain among underserved older African American and Latino patients in an under-resourced community such as South Los Angeles.
