Factors Associated with Depressive Symptoms among Mexican-Origin Adults in a Community Sample at the US Mexico Border Region.

Using baseline data from three partnering federally qualified health centers, we examined factors associated with depressive symptoms among Mexican-origin adults at risk of chronic disease living in three counties in Southern Arizona (i.e., Pima, Yuma, and Santa Cruz). Multivariable linear regression models identified correlates of depressive symptoms for this population controlling for sociodemographic characteristics. Among 206 participants, 85.9% were female and 49% were between 45 and 64 years of age. The proportion of depressive symptoms was 26.8%. Low levels of physical pain and high levels of hope and social support were also reported. Physical pain was positively and significantly related to depressive symptoms (ß = 0.22; 95% CI = 0.13, 0.30). Conversely, hope was negatively and significantly associated with depressive symptoms (ß = -0.53; 95% CI = -0.78, -0.29). A better understanding of factors related to depressive symptoms among Mexican-origin adults is necessary to fulfill their mental health needs, as well as to achieve health equity and to eliminate health disparities in the US-Mexico border region.

Chinese Oral Cancer Patients' Pain Beliefs: An Application of Leventhal's Common-Sense Model.

BACKGROUND: Patients' pain beliefs are the main obstacle to effective pain management. Assessing and correcting negative perceptions is important for improving pain intensity and quality of life of patients with cancer pain. AIMS: To explore pain beliefs among oral cancer patients using the Common-Sense Model of Self-Regulation as a theoretical framework. The primary components of the model, cognitive representations, emotional representations, and coping responses, were examined. DESIGN: A qualitative method was used. SETTINGS: PARTICIPANTS/SUBJECTS:   METHODS: Semi-structured, qualitative, in-depth interviews were conducted with patients newly diagnosed with oral cancer in a tertiary care hospital. The interviews were analyzed using thematic analysis. RESULTS: Interviews with 15 patients revealed that the pain beliefs of patients with oral cancer included three themes: pain cognitive representations of oral cancer, pain emotional representations of oral cancer, and pain coping responses. CONCLUSIONS: Negative pain beliefs are common among oral cancer patients. This novel application of the self-regulatory model demonstrates that it can be used to capture the key pain beliefs (i.e., cognitions, emotions, and coping responses) of oral cancer patients within a single, unifying framework.

Increasing Pain Interference Is Associated With Cognitive Decline Over Four Years Among Older Puerto Rican Adults.

BACKGROUND: Pain is associated with cognitive decline among older adults, but few studies have investigated bidirectional associations between pain and cognitive decline, especially in older Hispanic populations. Our objective was to assess the bidirectional association between pain interference and cognitive performance in a sample of older Puerto Rican adults. METHODS: Data came from baseline and 4-year follow-up of the Puerto Rican Elderly: Health Conditions Study, a longitudinal representative study of Puerto Rican older adults aged 60 and older. Pain and cognitive performance were assessed at each wave. A pain interference variable was created using the sum of pain status (yes/no) and pain interference (yes/no; range 0-2). Global cognitive performance was assessed with the Mini-Mental Cabán. We tested bidirectional associations using a path model with concurrent and cross-lagged paths between pain and cognitive performance, adjusting for sociodemographic and health factors (n = 2 349). RESULTS: Baseline pain interference was not associated with baseline cognitive performance (p = .636) or with cognitive performance at follow-up (p = .594). However, increased pain interference at follow-up was associated with greater cognitive decline at follow-up (ß = -0.07, standard error [SE] = 0.02, p = .003). Greater baseline cognitive performance was associated with lower pain interference at follow-up (ß = -0.07, SE = 0.02, p = .007). CONCLUSIONS: These findings highlight the importance of worsening pain interference as a potentially modifiable risk factor for cognitive decline, as pain treatment options exist. Additionally, better baseline cognitive performance may be a protective factor for pain, providing further evidence of the dynamic relationship between pain and cognitive performance.

The Relationship Between Adverse Life Events and Endogenous Inhibition of Pain and Spinal Nociception: Findings From the Oklahoma Study of Native American Pain Risk (OK-SNAP).

Adverse life events (ALEs) are a risk factor for chronic pain; however, mechanisms underlying this association are not understood. This study examined whether cumulative ALE exposure impairs endogenous inhibition of pain (assessed from pain report) and spinal nociception (assessed from nociceptive flexion reflex; NFR) in healthy, pain-free Native Americans (n = 124) and non-Hispanic Whites (n = 129) during a conditioned pain modulation (CPM) task. Cumulative ALE exposure was assessed prior to testing by summing the number of potentially traumatic events experienced by each participant across their lifespan. Multilevel modeling found that ALEs were associated with NFR modulation during the CPM task even after controlling for general health, body mass index, sex, age, blood pressure, sleep quality, stimulation intensity, stimulus number, perceived stress, and psychological distress. Low exposure to ALEs was associated with NFR inhibition, whereas high exposure to ALEs was associated with NFR facilitation. By contrast, pain perception was inhibited during the CPM task regardless of the level of ALE exposure. Race/ethnicity did not moderate these results. Thus, ALEs may be pronociceptive for both Native Americans and non-Hispanic Whites by impairing descending inhibition of spinal nociception. This could contribute to a chronic pain risk phenotype involving latent spinal sensitization. PERSPECTIVE: This study found that adverse life events were associated with impaired descending inhibition of spinal nociception in a sample of Native Americans and non-Hispanic Whites. These findings expand on previous research linking adversity to chronic pain risk by identifying a proximate physiological mechanism for this association.

The complex relationships among race/ethnicity, social determinants, and opioid utilization.

OBJECTIVE: To examine individual- and community-level factors associated with racial/ethnic differences in individuals' opioid prescription use. DATA SOURCES: Outpatient opioid prescription utilization and demographic, socioeconomic, and health characteristics from a nationally representative sample of the US noninstitutionalized civilian population obtained from 2013-2016 Medical Expenditure Panel Survey (MEPS) data and combined with 2012-2016 American Community Survey data and 2015 Health Area Resources File data. STUDY DESIGN: We use the Oaxaca-Blinder decomposition method to disaggregate racial/ethnic differences in prescription opioid utilization into differences explained by underlying predisposing, enabling and need characteristics, and unexplained differences. DATA COLLECTION/EXTRACTION METHODS: We use restricted-use geographic identifiers to supplement the MEPS data with information on community characteristics and local health care resources. PRINCIPAL FINDINGS: The average annual rate of any outpatient opioid prescription use was higher for non-Hispanic whites (15.8%; standard errors [SE]: 0.3) than for non-Hispanic blacks and Hispanics by 1.4 percentage points (SE: 0.5) and 6.2 percentage points (SE: 0.4), respectively. The smaller difference between non-Hispanic blacks and whites is not explained by the differences in the risk factors, while almost all the difference between Hispanics and non-Hispanic whites can be explained by the differences in the means of the risk factors. The differences in the prevalence of pain, the rate of being United States-born, and the racial/ethnic composition of the community explain 2.4 (SE: 0.2), 1.4 (SE: 0.3), and 1.9 (SE: 0.4) percentage-point differences, respectively. Pain prevalence explains the difference regardless of opioid potency, while foreign-born status and community racial/ethnic composition explain the difference in higher-potency opioid utilization only. CONCLUSIONS: This study underscores the importance of accounting for both individual and community characteristics when investigating patterns in opioid use. Our results could assist policy makers in tailoring strategies to promote safer and more effective pain management based on individual and community characteristics.

King's Parkinson's disease pain scale cut-off points for detection of pain severity levels: A reliability and validity study.

BACKGROUND: Pain is one of the most common non-motor symptoms in Parkinson's disease (PD). Using an appropriate and specific measuring tool would be helpful in managing the pain. King's Parkinson's disease Pain Scale (KPPS) is an instrument designed to specifically measure pain in people with PD. PURPOSE: This study aimed to examine the psychometric properties of the Persian version of KPPS (KPPS-P) and its cut-off points for pain severity levels. METHODS: A total of 480 people with PD (with a mean (SD) age of 60.89 (10.98)) were recruited. The acceptability of KPPS-P was calculated. The structural validity and discriminant validity for different levels of pain was explored via the factor analysis, and Receiver Operating Characteristics (ROC) curves, respectively. Internal consistency, test-retest, and inter-rater reliability were estimated by Cronbach's alpha and Interclass Correlation coefficient (ICC). Convergent validity was established between KPPS-P and other scales including Visual Analog Scale-Pain, Douleur Neuropathic 4, Brief Pain Inventory, Short-form McGill Pain Questionnaire-2, and Parkinson's Disease-8. RESULTS: A significant floor effect was observed. The exploratory factor analysis revealed 4 factors. Cronbach's alpha and ICC values were higher than 0.80. The correlation range between KPPS-P and other scales was 0.35-0.76. Cut-off points of 0, 17, and 68 were obtained to discriminate pain severity levels between no pain, mild, moderate, and severe pain, respectively, with sensitivity and specificity above 0.80. CONCLUSION: Our results indicate that the Persian version of KPPS not only has acceptable psychometric properties to assess pain in PD but also has the ability to distinguish between different levels of pain severity.

Racial and ethnic variations in caregiving-related physical, emotional, and financial strain during COVID-19 among those caring for adult cancer patients.

PURPOSE: Cancer caregiving is shown to be a burdensome experience in typical times. The purpose of this study was to describe cancer caregivers' emotional, physical, and financial strain during the COVID-19 pandemic and compared to preCOVID-19, and explore racial and ethnic variations in caregiver strain. METHODS: We conducted a cross-sectional online survey using Lucid, LLC, incorporating quotas for race, ethnicity, gender and age. Caregivers had to be adults living in the USA and currently providing unpaid care to an adult cancer patient (i.e., during COVID-19) and prior to the pandemic. We assessed the caregivers' emotional, physical, and financial strain and asked them to compare to preCOVID-19 caregiving. Analyses included descriptive and linear regression adjusting for sociodemographic and caregiving-related variables. RESULTS: A total of 285 caregivers met eligibility, and most were nonHispanic white (72.3%) and female (59.6%). Based on a scale of "1: Much lower" to "5: Much higher", the financial, physical and emotional strain/stress experienced by caregivers compared to preCOVID-19 was, on average, 3.52 (SD: 0.82; range: 1-5) for financial strain, 3.61 (SD: 0.86; range: 1-5) for physical strain, and 3.88 (SD: 0.89; range: 1-5) for emotional stress. NonHispanic black caregivers were significantly more likely than nonHispanic white caregivers to indicate that caregiving-related financial strain was higher than preCOVID-19. Moreover, Hispanic caregivers compared to nonHispanic white caregivers reported caregiving-related emotional stress was higher than preCOVID-19. CONCLUSION: These findings suggest a need to be attentive to racial and ethnic variations in emotional and financial strain and provide targeted support in clinical care and via public policy during a public health crisis.

Comparisons of Depression, Sexual Function, and Quality of Life Between Women With Gynecological Cancers and Race-Matched Healthy Controls.

BACKGROUND: Although higher incidence and mortality of gynecological cancer (GynCa) are documented in black compared with white women, few studies have documented quality of life (QOL) or healthy control comparisons. OBJECTIVE: This study compared depression, sexual function, and QOL between patients with GynCa and race-matched healthy controls. METHODS: Patients with GynCa and healthy controls completed the Patient Health Questionnaire-9, Female Sexual Function Index, and Functional Assessment of Cancer Therapy-General measures at baseline; GynCa patients were assessed again at 6 months post-radiation therapy (RT). RESULTS: Analyses included 84 participants (51% white, 49% black), including 28 GynCa patients and 56 controls with similar marital status. Compared with healthy controls, patients were younger, had a higher body mass index, and had more depression (P = .01); 82% of the patients and 71% of the healthy controls met criteria for sexual dysfunction at baseline (P = .29). Patients pre-RT had greater sexual dysfunction and lower QOL (P = .001) than controls did; patients at 6-month post-RT showed improved sexual function scores compared with pre-RT, with similar results to controls. White GynCa patients reported less sexual desire (P = .02), more pain (P = .05), and lower total Female Sexual Function Index scores (P = .01) than did black GynCa patients. Both black and white GynCa patients reported lower total QOL than their race-matched controls did (P = .07 and P = .002). CONCLUSIONS: Women with GynCa reported more depression and lower QOL than did healthy controls pre-RT. Among GynCa patients, white women had more sexual dysfunction than black women did. IMPLICATIONS FOR PRACTICE: The differences in sexual dysfunction between white and black women with GynCa suggest developing guidelines directing routine sexual assessment and rehabilitation in women treated for GynCa.

Pain intensity, pain-related anxiety, and somatic and mental health symptoms: a test among latinx young adults.

Latinx individuals demonstrate significant pain-related health disparities compared to other racial/ethnic groups. Moreover, young adulthood (18-25 years of age) is a primary developmental window wherein pain-related health problems are first encountered and may be related to more severe somatic and mental health symptoms. Pain-related anxiety may be one mechanistic construct linking individual differences in the experience of pain intensity to poorer somatic experiences and mental health among Latinx young adults. Thus, the current study examined pain-related anxiety as an explanatory factor underlying the relationship between pain intensity and body vigilance, perceptions of health, worry, anxious arousal, and depressive symptoms among Latinx young adults. Participants included 401 Latinx young adults (Mage = 21 years; SD = 2.02; age range: 18-25 years; 83% female) at a large, southwestern university. Results revealed that individual differences in pain intensity had a significant indirect effect on the studied somatic and negative affect variables through pain-related anxiety. These novel findings suggest future work should continue to explore pain-related anxiety in the association between the experience of pain and somatic and mental health among Latinx young adults.

Reencuentros con el dolor: Autoetnografía / Reuniting with pain: Self-ethnography

El recordar circunstancias que condujeron a sufrimiento en la vida es un proceso complejo; se revive situaciones que muchas veces se desean olvidar, pero que son parte importante en la construcción de la subjetividad. Nos pareció pertinente volver a revisar la experiencia de una de las investigadoras, sometida a varias intervenciones quirúrgicas y con dolor crónico. Se hizo uso del método autoetnográfico que, a través de indagar la memoria y la vivencia, busca reconocer los significados de dolor postquirúrgico que aporten al repensar el cuidado de enfermería. Este trabajo visibiliza las memorias de cuidado vividas alrededor del sufrimiento de dolor posquirúrgico, considerado uno de los principales problemas de calidad asistencial.

Remembering circumstances that led to suffering in life is a complex process, reviving situations that often wish to forget but are an important part in the construction of subjectivity. It seemed pertinent to revisit the experience of one of the researchers, who underwent several surgical interventions and with chronic pain. We used the autoethnographic method that, through investigating memory and experience, seeks to recognize the meanings of postsurgical pain that contribute to rethinking nursing care. This work brings together the memories of care lived around the suffering of post-surgical pain, considered one of the main problems of quality of care.

Parent responses to pediatric pain: The differential effects of ethnicity on opioid consumption.

OBJECTIVE: Within the context of the United States opioid epidemic, some parents often fear the use of opioids to help manage their children's postoperative pain. As a possible consequence, parents often do not dispense optimal analgesic medications to their children after surgery, putting their children at risk of suffering from postsurgical pain. The objective of this research was to assess ethnicity as a predictor of both pain and opioid consumption, and to examine how Hispanic/Latinx and Non-Hispanic White parents alter their child's opioid consumption in response to significant postsurgical pain. METHODS: Participants were 254 children undergoing outpatient tonsillectomy and/or adenoidectomy surgery and their parents. Longitudinal multilevel modeling examined changes in both parent-reported pain and hydrocodone/APAP consumption (mg/kg) on days 1 to 7 after surgery. RESULTS: Parent reports of postoperative pain were higher in Hispanic/Latinx patients compared to their Non-Hispanic White counterparts (ß = -0.15; 95% CI: -0.28, -0.01). There was also a significant interaction of ethnicity and pain on opioid consumption (ß = 0.07; 95% CI: 0.01, 0.13). The relationship between parent perceived pain and opioid use was stronger for Non-Hispanic White children, suggesting that this group was more likely to consume opioids to help manage clinically significant postsurgical pain. CONCLUSIONS: Hispanic/Latinx children might be at risk for undertreatment of surgical pain. Findings highlight the importance of assessing parent background and cultural beliefs as predictors of at home pain management and the potential effectiveness of tailored interventions that educate parents about monitoring and treating child postoperative pain.

In Attention to Pain: Governance and Bodies in Brazil.

Ethnographies of bodies have become entry points for understanding the sensorially rich ways that worlds are generated and lived. Here, I adduce a slow-paced ethnographic mode that centers how bodily pain and touch orient attention, with a focus on gendered and racialized violence in the suburbs of Rio de Janeiro. In doing so, I make explicit the expectation in Rio's urban governance that resilience means toughening through pain. In turn, I detail how Pentecostal practices of 'healing touch' link pain and hope together, demonstrating the religious work, care, and governance involved in producing and maintaining hope under conditions of violence.

Temporal Factors Associated With Opioid Prescriptions for Patients With Pain Conditions in an Urban Emergency Department.

Importance: Opioid prescriptions for treatment of pain in emergency departments (EDs) are associated with long-term opioid use. The temporal pattern of opioid prescribing in the context of the opioid epidemic remains unknown. Objective: To examine the temporal pattern of opioid prescribing within an ED for varying pain conditions between 2009 and 2018. Design, Setting, and Participants: A population-based, cross-sectional study was conducted at the ED of an urban academic medical center. All patients treated within that ED between January 1, 2009, and December 31, 2018, were included. Main Outcomes and Measures: The proportion of patients prescribed an opioid for treatment of pain in the ED temporally by condition, condition type, patient demographics, and physician prescriber. Results: Between 2009 and 2018, 556 176 patient encounters took place in the ED, with 70 218 unique opioid prescriptions ordered. A total of 316 632 patients (55.9%) were female, 45 070 (42.6%) were of white race, and 43 412 (40.6%) were privately insured; the median age group was 41 to 45 years. Yearly opioid prescriptions decreased by 66.3% (from 16.3 to 5.5 opioids per 100 encounters) between 2013 and 2018, with a yearly adjusted odds ratio (aOR) of 0.808 (95% CI, 0.802-0.814) compared with the prior year. In patients with musculoskeletal pain (back, joint, limb, and neck pain), opioid prescribing decreased by 71.1% (from 36.7 to 10.6 opioids per 100 encounters between 2013 and 2018; aOR, 0.758; 95% CI, 0.744-0.773). In patients with musculoskeletal trauma (fracture, sprain, contusion, and injury), opioid prescribing decreased by 58.0% (from 34.2 to 14.8 opioids per 100 encounters; aOR, 0.811; 95% CI, 0.797-0.824). In patients with nonmusculoskeletal pain (abdominal pain, kidney stone, respiratory distress, and pharyngitis) opioid prescribing decreased by 53.7% (from 20.1 to 9.3 opioids per 100 encounters; aOR, 0.850; 95% CI, 0.834-0.868). Between 2009 and 2018, patients who were black (aOR, 0.760; 95% CI, 0.741-0.779) and those who were Asian (aOR, 0.714; 95% CI, 0.665-0.764) had the lowest odds of receiving an opioid compared with other racial/ethnic groups. Conclusions and Relevance: There was a substantial temporal decrease in the number of opioid prescriptions within this ED during the study period. This decrease was associated with substantial relative reductions in opioid prescribing for treatment of musculoskeletal pain compared with fractures and kidney stones.

The Effect of Pain Catastrophizing on Endogenous Inhibition of Pain and Spinal Nociception in Native Americans: Results From the Oklahoma Study of Native American Pain Risk.

BACKGROUND: Conditioned pain modulation (CPM) is a task that involves measuring pain in response to a test stimulus before and during a painful conditioning stimulus (CS). The CS pain typically inhibits pain elicited by the test stimulus; thus, this task is used to assess endogenous pain inhibition. Moreover, less efficient CPM-related inhibition is associated with chronic pain risk. Pain catastrophizing is a cognitive-emotional process associated with negative pain sequelae, and some studies have found that catastrophizing reduces CPM efficiency. PURPOSE: The current study examined the relationship between catastrophizing (dispositional and situation specific) and CPM-related inhibition of pain and the nociceptive flexion reflex (NFR; a marker of spinal nociception) to determine whether the catastrophizing-CPM relationship might contribute to the higher risk of chronic pain in Native Americans (NAs). METHODS: CPM of pain and NFR was assessed in 124 NAs and 129 non-Hispanic Whites. Dispositional catastrophizing was assessed at the beginning of the test day, whereas situation-specific catastrophizing was assessed in response to the CS, as well as painful electric stimuli. RESULTS: Situation-specific, but not dispositional, catastrophizing led to less NFR inhibition but more pain inhibition. These effects were not moderated by race, but mediation analyses found that: (a) the NA race was associated with greater situation-specific catastrophizing, which led to less NFR inhibition and more pain inhibition, and (b) situation-specific catastrophizing was associated with greater CS pain, which led to more pain inhibition. CONCLUSIONS: Catastrophizing may contribute to NA pain risk by disrupting descending inhibition.

Neural and sociocultural mediators of ethnic differences in pain.

Understanding ethnic differences in pain is important for addressing disparities in pain care. A common belief is that African Americans are hyposensitive to pain compared to Whites, but African Americans show increased pain sensitivity in clinical and laboratory settings. The neurobiological mechanisms underlying these differences are unknown. We studied an ethnicity- and gender-balanced sample of African Americans, Hispanics and non-Hispanic Whites using functional magnetic resonance imaging during thermal pain. Higher pain report in African Americans was mediated by discrimination and increased frontostriatal circuit activations associated with pain rating, discrimination, experimenter trust and extranociceptive aspects of pain elsewhere. In contrast, the neurologic pain signature, a neuromarker sensitive and specific to nociceptive pain, mediated painful heat effects on pain report largely similarly in African American and other groups. Findings identify a brain basis for higher pain in African Americans related to interpersonal context and extranociceptive central pain mechanisms and suggest that nociceptive pain processing may be similar across ethnicities.

Assessing peripheral fibers, pain sensitivity, central sensitization, and descending inhibition in Native Americans: main findings from the Oklahoma Study of Native American Pain Risk.

Native Americans (NAs) have a higher prevalence of chronic pain than other U.S. racial/ethnic groups, but there have been few attempts to understand the mechanisms of this pain disparity. This study used a comprehensive battery of laboratory tasks to assess peripheral fiber function (cool/warm detection thresholds), pain sensitivity (eg, thresholds/tolerances), central sensitization (eg, temporal summation), and pain inhibition (conditioned pain modulation) in healthy, pain-free adults (N = 155 NAs, N = 150 non-Hispanic Whites [NHWs]). Multiple pain stimulus modalities were used (eg, cold, heat, pressure, ischemic, and electric), and subjective (eg, pain ratings and pain tolerance) and physiological (eg, nociceptive flexion reflex) outcomes were measured. There were no group differences on any measure, except that NAs had lower cold-pressor pain thresholds and tolerances, indicating greater pain sensitivity than NHWs. These findings suggest that there are no group differences between healthy NAs and NHWs on peripheral fiber function, central sensitization, or central pain inhibition, but NAs may have greater sensitivity to cold pain. Future studies are needed to examine potential within-group factors that might contribute to NA pain risk.

A Cross-sectional Study of Gender-related Differences in Reporting Fatigue and Pain among Latino/A Migrant Farmworkers.

Objectives: Migrant farmworkers face many hardships in both their working and living environments including dangerous and demanding tasks, long hours, and inadequate rest. This study sought to explore gender differences in the reporting of fatigue and pain and to identify predictors of fatigue and pain among migrant farmworkers in Nebraska (n = 241). Methods: Bivariate tests were used to assess associations among study variables. Linear and generalized linear mixed effect models were used to assess gender as a predictor of fatigue and pain respectively while controlling for covariates. Results: Females reported significantly higher levels of fatigue (M score = 15.5, SD = 6.1 compared to M score = 12.8, SD = 4.3) than their male counterparts. Females were also more likely to report pain (56.9% of females compared to 36.3% of males). Being female, pain, hours of sleep, and job demands were significant predictors of fatigue. Fatigue and job-related injury were the only significant predictors of pain. Conclusions: There are gender-related disparities in the reporting of fatigue and pain among Latino/a migrant farmworkers. Extra precautions need to be taken to protect worker health and safety and reduce fatigue, particularly for female workers. Implications for employers, supervisors, and healthcare providers are discussed.

Understanding Racial/Ethnic Disparities in Physical Performance in Midlife Women: Findings From SWAN (Study of Women's Health Across the Nation).

OBJECTIVES: Evaluate degree to which racial/ethnic differences in physical performance are mediated by sociodemographic, health, behavioral, and psychosocial factors. METHODS: Physical performance was evaluated using a decile score derived from grip strength, timed 4 m walk, and timed repeat chair stand in 1,855 African American, Caucasian, Chinese, Hispanic, and Japanese women, mean age = 61.8 (SD = 2.7) in the Study of Women's Health Across the Nation. Mediators included education, financial strain, comorbidities, pain, body mass index (BMI), physical activity, and perceived stress. Structural equation models provided estimates of the total difference in physical performance between Caucasians and each race/ethnic groups and differences due to direct effects of race/ethnicity and indirect effects through mediators. RESULTS: The mean decile score for Caucasian women was 16.9 (SD = 5.6), 1.8, 2.6, and 2.1 points higher than the model-estimated scores in African Americans, Hispanics and Chinese, respectively, and 1.3 points lower than the Japanese. Differences between Caucasians and the Chinese and Japanese were direct effects of race/ethnicity whereas in African Americans and Hispanics 75% or more of that disparity was through mediators, particularly education, financial strain, BMI, physical activity, and pain. DISCUSSION: Addressing issues of poverty, racial inequality, pain, and obesity could reduce some racial/ethnic disparity in functional limitations as women age.

Mixed studies review of factors influencing receipt of pain treatment by injured black patients.

AIM: To explore the factors that influence provider pain treatment decision-making and the receipt of pain management by injured Black patients in the United States. DESIGN: We completed a systematic mixed studies review using a results-based convergent synthesis design. DATA SOURCES: PubMed, SCOPUS and CINAHL were searched for articles published between 2007-2017 using the search terms 'African American', 'Black American', 'race', 'pain treatment', 'pain management' and 'analgesia'. Twenty studies were included in this review. REVIEW METHOD: A search of databases and hand-searching identified peer-reviewed published papers. The Mixed Method Appraisal Tool was used to appraise the studies. RESULTS: The results indicate that healthcare provider characteristics, racial myths about pain sensitization and assumed criminality all impact provider treatment decision-making and the receipt of pain treatment by injured Black patients. IMPACT: This review addresses racial disparities in pain management by focusing on the factors that impact the receipt of pain treatment by injured Black patients. The findings will have an impact on providers who prescribe pain treatment and on the patients they treat. These findings suggest that assumed criminality of certain patients can negatively impact care, which is a type of bias not frequently explored or discussed in health disparities research. This review will help inform further research in healthcare disparities and prompt providers to examine their assumptions about the patients for whom they care. CONCLUSION: These results provide important areas for further study, including how assumed criminality of certain patients can have a negative impact on care.

Prescription Opioid Use Among Hispanics/Latinos With Arthritis Symptoms: Results From the Hispanic Community Health Study/Study of Latinos.

INTRODUCTION: To determine the prevalence of prescription opioid (PO) use among Hispanics/Latinos with arthritis symptoms and to characterize how demographic and cultural factors are associated with PO use. METHOD: Cross-sectional analysis of baseline visit data during 2008 to 2011 from the Hispanic Community Health Study/Study of Latinos, a population-based cohort study of 16,415 Hispanics/Latinos living in Chicago, Illinois, Miami, Florida, Bronx, New York, and San Diego, California. Included participants self-reported painful inflammation or swelling in one or more joints. Multivariate models controlling for physical and mental health scores were constructed to assess how demographic and cultural factors were associated with PO use. RESULTS: A total of 9.3% were using POs at the time of the baseline visit. In multivariate models, persons of Cuban background (adjusted odds ratio [AOR] = 0.42, 95% confidence interval [CI; 0.21, 0.81]) and of Dominican background (AOR = 0.38, 95% CI [0.18, 0.80]) were significantly less likely to use POs compared with a reference group of persons of Mexican background. Greater language acculturation was also negatively associated with PO use (AOR = 0.68, 95% CI [0.53, 0.87]). CONCLUSION: POs were used relatively uncommonly, and use showed marked variation between Hispanic/Latino groups. Future study should determine mechanisms for why greater use of English among Hispanics/Latinos might influence PO use.
