Patterns and Correlates of Self-Management Strategies for Osteoarthritis-Related Pain Among Older Non-Hispanic Black and Non-Hispanic White Adults.

OBJECTIVE: Knee osteoarthritis (OA) is a leading source of pain and disability among older adults. Self-management (SM) strategies are recommended to manage OA symptoms. Sociodemographic and clinical characteristics, along with other factors, may influence SM utilization rate. This study sought to examine the prevalence and correlates of SM use for pain among non-Hispanic Black patients (NHB) and non-Hispanic White patients (NHW) older adults with or at risk for knee OA. METHODS: A secondary data analysis was conducted on the Understanding Pain and Limitations in Osteoarthritic Disease multisite observational study, which included NHB (n = 104) and NHW (n = 98) community-dwelling older adults with or at risk for knee OA. Participants completed measures of sociodemographics, pain SM use, coping, and clinical and experimental pain. RESULTS: Clinical and experimental pain were significantly greater among NHBs compared to NHWs. There were no significant differences in use of total SM by ethnicity/race. Interestingly, multiple linear regression revealed that clinical and experimental pain indices, as well as coping, number of pain sites, age, and sex were differentially associated with total SM use between NHBs and NHWs. There were significant ethnicity/race by type of pain management interaction effects for pain measures. CONCLUSION: SM is common among older adults with or at risk for knee OA pain, and the prevalence of SM does not differ by ethnicity/race, but many guideline-recommended interventions for OA are underutilized. Importantly, different factors were associated with the use of SM, highlighting distinct biopsychosocial mechanisms contributing to SM use in NHBs and NHWs.

Cumulative Disadvantage and Disparities in Depression and Pain Among Veterans With Osteoarthritis: The Role of Perceived Discrimination.

OBJECTIVE: Perceived discrimination is associated with chronic pain and depression and contributes to racial health disparities. In a cohort of older adult veterans with osteoarthritis (OA), our objective was to examine how membership in multiple socially disadvantaged groups (cumulative disadvantage) was associated with perceived discrimination, pain, and depression. We also tested whether perceived discrimination mediated the association of cumulative disadvantage with depression and pain. METHODS: We analyzed baseline data from 270 African American veterans and 247 White veterans enrolled in a randomized controlled trial testing a psychological intervention for chronic pain at 2 Department of Veterans Affairs medical centers. Participants were age ≥50 years and self-reported symptomatic knee OA. Measures included the Everyday Discrimination Scale, the Patient Health Questionnaire Depression Scale, the Western Ontario and McMaster Universities Osteoarthritis Index pain subscale, and demographic variables. Cumulative disadvantage was defined as the number of socially disadvantaged groups to which each participant belonged (i.e., self-reported female sex, African American race, annual income of <$20,000, and/or unemployed due to disability). We used linear regression models and Sobel's test of mediation to examine hypotheses. RESULTS: The mean ± SD number of social disadvantages was 1.3 ± 1.0. Cumulative disadvantage was significantly associated with higher perceived discrimination, pain, and depression (P < 0.001 for all). Perceived discrimination significantly mediated the association between cumulative disadvantage and depression symptoms (Z = 3.75, P < 0.001) as well as pain severity (Z = 2.24, P = 0.025). CONCLUSION: Perceived discrimination is an important psychosocial stressor that contributes to worsening OA-related mental and physical health outcomes, with greater effects among those from multiple socially disadvantaged groups.

Potential Role of Cost and Quality of Life in Treatment Decisions for Arthritis-Related Knee Pain in African American and Latina Women.

OBJECTIVE: The present study was undertaken to investigate whether Latina and African American women with arthritis-related knee pain and primary care providers who treat them believe their treatment decisions would benefit from having more information about the impact of treatment on their quality of life, medical care costs, and work productivity. METHODS: We conducted 4 focus groups of Latina and African American women over age 45 years who had knee pain. We also conducted 2 focus groups with primary care providers who treated Latina and African American women for knee pain. The participants were recruited from the community. They were asked their opinions about a decision tool that presented information on a range of treatment options and their impacts on quality of life, medical care costs, and work productivity. They were asked whether providing this information would help them make better treatment decisions. We analyzed the focus group transcripts using ATLAS.ti. RESULTS: We found that minority women and primary care providers endorsed the use of a decision-making tool that provided information of the impact of treatment on quality of life, medical care costs, and work productivity. Providers felt that patients would benefit from having the additional information but were concerned about its complexity and some patients' ability to comprehend the information. CONCLUSION: Latina and African American women could make more informed treatment decisions for their knee pain using a decision-making tool that provides them with significant information about how various treatment options may impact their quality of life, medical care costs, and workforce productivity.

The importance of assessment and management of morning stiffness in Asian patients with rheumatoid arthritis: Recommendations from an expert panel.

OBJECTIVE: In patients with rheumatoid arthritis (RA), morning stiffness is linked more to functional disability and pain than disease activity, as assessed by joint counts and markers of inflammation. As part of the Asia Pacific Morning Stiffness in Rheumatoid Arthritis Expert Panel, a group of eight rheumatologists met to formulate consensus points and develop recommendations for the assessment and management of morning stiffness in RA. METHODS: On the basis of a systematic literature review and expert opinion, a panel of Asian rheumatologists formulated recommendations for the assessment and medical treatment of RA. RESULTS: The panel agreed upon 10 consensus statements on morning stiffness, its assessment and treatment. Specifically, the panel recommended that morning stiffness, pain and impaired morning function should be routinely assessed in clinical practice. Although there are currently no validated tools for these parameters, they should be assessed as part of the patients' reported outcomes in RA. The panel also agreed on the benefits of low-dose glucocorticoids in RA, particularly for the improvement of morning stiffness. CONCLUSIONS: These recommendations serve to guide rheumatologists and other stakeholders on the assessment and management of morning stiffness, and help implement the treat-to-target principle in the management of RA.

Does Race Affect Outcomes in Total Joint Arthroplasty?

BACKGROUND: Several studies suggest worse surgical outcomes among racial/ethnic minorities. There is a paucity of research on preoperative and postoperative pain, general health, and disease-specific measures in which race is the main subject of investigation; furthermore, the results are not conclusive. QUESTIONS/PURPOSES: (1) Do black patients have more severe or more frequent preoperative pain, well-being, general health, and disease-specific scores when compared with white patients? (2) Are there differences between black patients and white patients after hip or knee arthroplasty on those same measures? METHODS: In this retrospective study, we used an institutional arthroplasty registry to analyze data on 2010 primary arthroplasties (1446 knees and 564 hips) performed by one surgeon at a single institution. Cases from patients self-identifying as black (n = 105) and white (n = 1905) were compared (controlling for confounders, including age and ethnicity) on the following preoperative and postoperative patient-oriented outcomes: pain intensity/frequency as measured by a visual analog scale (VAS), Quality of Well-Being (QWB-7), SF-36, and WOMAC scores. T-tests, chi square, and multivariate analysis of covariance were used. Alpha was set at 0.05. Postoperative analysis was performed only on those cases that had a minimum followup of 1 year (mean, 3.5 years; range, 1-9 years). Of the 2010 arthroplasties, 37% (39 of 105) of those cases performed in black patients and 64% (1219 of 1905) of those performed in white patients were included in the final postoperative model (multivariate analysis of covariance). RESULTS: Black patients had more severe preoperative pain intensity (VAS: 8 ± 1.8 versus 8 ± 2.0, mean difference = 0.76 [95% confidence interval {CI}, 0.34-1.1], p < 0.001). Black patients also had worse well-being scores (QWB-7: 0.527 ± 0.04 versus 0.532 ± 0.05, mean difference = -0.01 [CI, -0.02 to 0.00], p = 0.037). Postoperatively, pain intensity (VAS: 1 ± 3.1 versus 1 ± 1.8, mean difference= 0.8 [CI, 0.19-1.4], p= 0.010) and (QWB-7: 0.579 ± 0.09 versus 0.607 ± 0.11, mean difference= -0.049 [CI, -0.08 to -0.01], p = 0.008) were different but without clinical significance. CONCLUSIONS: Black patients underwent surgery earlier in life and with different preoperative diagnoses when compared with white patients. Black patients had worse preoperative baseline pain, well-being, general health, and disease-specific scores as well as worse postoperative scores. However, these differences were very narrow and without clinical significance. Notwithstanding, the relations of race with outcomes remain complex. Further investigations to recognize disparities and minimize or address them are warranted. LEVEL OF EVIDENCE: Level III, prognostic study.

Severe menopausal symptoms in mid-aged Latin American women can be related to their indigenous ethnic component.

BACKGROUND: Latin American women present more severe menopausal symptoms when compared to those from other regions of the world. Since this population is an ethnic blend of Caucasian and indigenous people, we sought to test the hypothesis that severe menopausal symptoms in Latin American women are associated with an indigenous origin. OBJECTIVE: To assess menopausal symptoms among two specific indigenous Latin American populations. METHOD: A total of 573 natural postmenopausal indigenous women aged 45-59 years (288 Quechua (Peru) and 285 Zenú (Colombia)) living in isolated communities were surveyed with a general questionnaire and the Menopause Rating Scale (MRS). RESULTS: The total MRS score was significantly higher among Quechua women as compared to Zenú ones (22.7 ± 5.7 vs. 14.7 ± 2.5, p < 0.0001); both figures were higher than those described for Hispanic or European populations. Quechua women presented more intense somatic and psychological symptoms as compared to Zenú (8.8 ± 2.3 vs. 5.3 ± 1.8; and 7.8 ± 2.4 vs. 3.2 ± 1.7, p < 0.0001); however, both indigenous groups presented similar intense urogenital symptoms (6.1 ± 1.6 vs. 6.2 ± 1.4, not significant). These differences persisted after adjusting for age, years since menopause onset and parity. The percentage of women presenting severe somatic and psychological symptoms significantly increased with aging among Quechua. This was not the case for Zenú women. More than 90% of indigenous women (Quechua and Zenú) at all age intervals presented severe urogenital scores, a percentage that is much higher than that described in the world literature. CONCLUSION: Severe menopausal symptoms found among Latin American women could be the result of their indigenous ethnic origin; the urogenital domain is the most affected.

Increased menopausal symptoms among Afro-Colombian women as assessed with the Menopause Rating Scale.

BACKGROUND: Increased frequency and severity of menopausal symptoms have been associated to black race. However, this situation has not been described in any Latin American population. OBJECTIVE: Compare frequency and severity of menopausal symptoms among Afro and non-Afro Hispanic Colombian climacteric women. METHODS: In this cross-sectional study, healthy Afro and non-Afro-Colombian women aged 40-59 years were asked to fill out the Menopause Rating Scale (MRS) questionnaire in order to compare symptom frequency and intensity. RESULTS: A total of 578 women were surveyed (201 Afro-Colombian and 377 non-Afro-Colombian). Mean age of the whole sample was 47.9+/-5.9 years (median 47), with no differences among studied groups in terms of age, parity, and hormone therapy (HT) use. Intensity of menopausal symptoms, assessed with the total MRS score, was found to be significantly higher among Afro-Colombian women (10.6+/-6.7 vs. 7.5+/-5.7, p=0.0001), which was due to higher somatic and psychological subscale scores. In this group, the frequency of somatic symptoms, heart discomfort and muscle and joint problems, was found to be higher than in non-Afro-Colombian women (38.8% vs. 26.8% and 77.1% vs. 43.5%, respectively, p<0.05); equally, all items of the psychological subscale (depressive mood, irritability, anxiety and physical exhaustion) were also found to be higher among black women. On the other hand, compared to black women non-Afro-Colombian ones presented more bladder problems (24.9% vs. 14.9%, p=0.005). After adjusting for confounding factors, logistic regression analysis determined that black race increased the risk for presenting higher total MRS scorings (OR: 2.31; CI 95%: 1.55-3.45, p=0.0001). CONCLUSION: Despite the limitations of this study, as determined with the MRS Afro-Colombian women exhibited more impaired quality of life (QoL) when compared to non-Afro-Colombian ones, due to a higher rate and severity of menopausal somatic and psychological symptoms.
