Educational achievement and pain disability among women with chronic pelvic pain

"I wish I knew then what I know now" - pain science education concepts important for female persistent pelvic pain: a reflexive thematic analysis

ABSTRACT

Pain science education (PSE) provides people with an understanding of "how pain works" grounded in the biopsychosocial model of pain; it has been demonstrated to improve outcomes in musculoskeletal pain conditions. Preliminary evidence suggests PSE may be effective for female individuals with persistent pelvic pain, but how the content of PSE needs to be modified for this group remains to be determined. A reflexive thematic analysis of qualitative data was performed to identify PSE concepts that female individuals with persistent pelvic pain consider important and why. Twenty individual, semistructured interviews were conducted with adult females who had engaged with PSE and had self-identified as having "improved" pelvic pain. Most participants had been diagnosed with endometriosis (n = 16). Four themes were generated capturing PSE concepts considered important by female individuals with "improved" pelvic pain: (1) "A sensitised nervous system leads to overprotective pain" validated their pelvic pain as being real; (2) "Pain does not have to mean the body is damaged (although sometimes it does)" provided reassurance that pelvic pain does not mean their condition is worsening; (3) "How I think, feel, and 'see' my pain can make it worse" enabled participants to find optimal ways to manage their pain; and (4) "I can change my pain… slowly" provided hope that pelvic pain can improve and empowered them to pursue pain improvement as a viable goal. This study generated 4 PSE learning concepts that were important to female individuals with improved pelvic pain and may be incorporated into PSE curricula for female individuals with pelvic pain.

Addressing chronic pain disparities between Black and White people: a narrative review of socio-ecological determinants

A 2019 review article modified the socio-ecological model to contextualize pain disparities among different ethnoracial groups; however, the broad scope of this 2019 review necessitates deeper socio-ecological inspection of pain within each ethnoracial group. In this narrative review, we expanded upon this 2019 article by adopting inclusion criteria that would capture a more nuanced spectrum of socio-ecological findings on chronic pain within the Black community. Our search yielded a large, rich body of literature composed of 174 articles that shed further socio-ecological light on how chronic pain within the Black community is influenced by implicit bias among providers, psychological and physical comorbidities, experiences of societal and institutional racism and biomedical distrust, and the interplay among these factors. Moving forward, research and public-policy development must carefully take into account these socio-ecological factors before scaling up pre-existing solutions with questionable benefit for the chronic pain needs of Black individuals.

Incidence of Chronic Pelvic Pain in Females Attending a Gynaecology Outpatient Department

Background and Aims: Chronic pelvic pain (CPP) is a persistent pelvic pain that leads to reduced work performance and impaired quality of life in females. Nearly 15% of females report time off from paid work and around 45% report reduced work productivity. There is a paucity of studies to address the issue, especially with a multidisciplinary and multifactorial view. Various gynaecological disorders are associated with CPP such as endometriosis, adenomyosis, adhesions, chronic pelvic inflammatory disease, and pelvic congestion syndrome. The objective is to determine the frequency of CPP in females attending gynaecologic outpatient departments. Materials and Methods: A total of 201 patients aged 14–48 years attending the gynaecologic outpatient department for gynaecological disorders with complaints of lower abdominal pain were included in this study. Patients enrolled in the study were assessed by a detailed history and pelvic examination, and a structured questionnaire was filled out. Data were analysed using the statistical package for social sciences version 23.0 (International Business Machines Corporation, Armonk, New York, USA). Results: The mean age of the patients was 32.39±6.98 years. The frequency of CPP in females was observed as 95.52% (95% confidence interval: 91.67–97.93%) The rate of CPP was significantly high in females with parity ≤5 and those who had a duration of pain lower than 36 months. In multivariate analysis, adjusted odds ratio by stepwise logistic regression model showed that parity (parity 0–1) and duration of pain (≤36 months) were significantly associated with CPP in females. Conclusion: The study indicates that the most common gynaecological causes of CPP in females attending the outpatient department were those with endometriosis followed by adenomyosis. The management of CPP needs patient-centred care with a multidisciplinary approach. This will lead to early and effective management.

Health literacy and health outcomes in patients with low back pain: a scoping review

BACKGROUND

Low back pain is a leading cause of disability worldwide. Health literacy has been associated with pain intensity and pain control. However, there is a paucity of evidence regarding this association. In the field of low back pain research, inconsistent reporting of outcomes has been highlighted. To address this issue a Core Outcome Set has been developed.

OBJECTIVES

The objectives of this scoping review were: (1) The health literacy measures currently employed for low back pain and the aspects of health literacy they include. (2) The low back pain health outcomes included in such work. (3) The extent to which these health outcomes reflect the Core Outcome Set for Clinical Trials in Non-Specific Low Back Pain.

METHODS

The search included thirteen bibliographic databases, using medical subject heading terms for low back pain and health literacy, and followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines. The eligibility criteria were defined by the Joanna Briggs Institute PCC mnemonic. A thematic framework approach was used for analysis.

RESULTS

The search yielded ten relevant studies for inclusion, amongst which a total of nine health literacy measures and 50 health outcome measures were used. Most health literacy measures focused on functional health literacy, with few assessing communicative and critical health literacy. The health outcomes assessed by the included studies could be broadly categorised into: Pain, Disability, Behaviour, Knowledge and Beliefs, and Resource Utilisation. Most of these outcome measures studied (36 out of 50) did not directly reflect the Core Outcome Set for Clinical Trials in Non-Specific Low Back Pain.

CONCLUSIONS

To allow for comparison across findings and the development of a rigorous evidence base, future work should include the Core Outcome Set for Clinical Trials in Non-Specific Low Back Pain. There is an urgent need to broaden the evidence-base to include regions where low back pain morbidity is high, but data is lacking. Such work demands the incorporation of comprehensive measures of health literacy that have both generic and culturally sensitive components.

Cross-sectional study of psychosocial and pain-related variables among patients with chronic pain during a time of social distancing imposed by the coronavirus disease 2019 pandemic

ABSTRACT

The COVID-19 pandemic has had a tremendous impact, including on individuals with chronic pain. The social distancing policies necessary to slow the spread of SARS-CoV-2 have involved increased levels of social isolation. This cross-sectional survey study examined pain severity and interference among individuals with chronic pain during an early phase of social distancing mandates and identified characteristics of individuals who were most impacted. Approximately 4 to 8 weeks after social distancing mandates commenced in the state of Massachusetts, 150 patients with fibromyalgia, chronic spine, and postsurgical pain completed demographic, pain, social distancing, and validated psychosocial questionnaires. Patients self-reported an overall significant increase in pain severity and pain interference, compared with before social distancing, although both pain severity and interference were quite variable among individuals under conditions of social distancing. Several demographic, socioeconomic, and psychosocial factors were associated with greater pain severity and interference during social distancing. Multivariable linear regression demonstrated that female sex, nonwhite race, lower education, disability, fibromyalgia, and higher pain catastrophizing were independently associated with greater pain severity, while female sex and pain catastrophizing were independently associated greater pain interference. The findings suggest that individual differences among patients with chronic pain should be considered in the planning, development, and prioritization of interventions to improve pain care and to prevent worsening of symptoms during the continuing COVID-19 pandemic.

Pharmacogenomics of Pain Management: The Impact of Specific Biological Polymorphisms on Drugs and Metabolism

PURPOSE OF REVIEW

Pain is multifactorial and complex, often with a genetic component. Pharmacogenomics is a relative new field, which allows for the development of a truly unique and personalized therapeutic approach in the treatment of pain.

RECENT FINDINGS

Until recently, drug mechanisms in humans were determined by testing that drug in a population and calculating response averages. However, some patients will inevitably fall outside of those averages, and it is nearly impossible to predict who those outliers might be. Pharmacogenetics considers a patient's unique genetic information and allows for anticipation of that individual's response to medication. Pharmacogenomic testing is steadily making progress in the management of pain by being able to identify individual differences in the perception of pain and susceptibility and sensitivity to drugs based on genetic markers. This has a huge potential to increase efficacy and reduce the incidence of iatrogenic drug dependence and addiction. The streamlining of relevant polymorphisms of genes encoding receptors, transporters, and drug-metabolizing enzymes influencing the pain phenotype can be an important guide to develop safe new strategies and approaches to personalized pain management. Additionally, some challenges still prevail and preclude adoption of pharmacogenomic testing universally. These include lack of knowledge about pharmacogenomic testing, inadequate standardization of the process of data handling, questionable benefits about the clinical and financial aspects of pharmacogenomic testing-guided therapy, discrepancies in clinical evidence supporting these tests, and doubtful reimbursement of the tests by health insurance agencies.

Pain Intensity among Community-Dwelling African American Older Adults in an Economically Disadvantaged Area of Los Angeles: Social, Behavioral, and Health Determinants

BACKGROUND

Although social, behavioral, and health factors influence prevalence and intensity of pain, very few studies have investigated correlates of pain among economically disadvantaged older African American (AA) adults.

OBJECTIVE

This study explored social, behavioral, and health correlates of pain intensity among community-dwelling AA older adults in an economically disadvantaged area of Los Angeles.

METHODS

A cross-sectional study on 740 AA older adults (age ≥ 55 years) was conducted in South Los Angeles between 2015 and 2018. Exploratory variables were age, gender, educational attainment, financial difficulties, living alone, marital status, smoking, drinking, pain-related chronic medical conditions (CMCs), and depressive symptoms. Dependent variable was pain intensity. Linear regression was used for data analysis.

RESULTS

Age, financial difficulties, living alone, smoking, pain-related chronic medical conditions, and depressive symptoms were associated with pain intensity. Individuals with lower age, higher financial difficulties, those who lived alone, those with a higher number of pain-related chronic medical conditions, more depressive symptoms, and nonsmokers reported more pain intensity. Gender, educational attainment, marital status, and drinking were not associated with pain intensity.

CONCLUSION

The results may help with the health promotion of economically disadvantaged AA older adults in urban areas.

Update on the pharmacogenomics of pain management

Pharmacogenomics is the study of genetic variants that impact drug effects through changes in a drug’s pharmacokinetics and pharmacodynamics. Pharmacogenomics is being integrated into clinical pain management practice because variants in individual genes can be predictive of how a patient may respond to a drug treatment. Pain is subjective and is considered challenging to treat. Furthermore, pain patients do not respond to treatments in the same way, which makes it hard to issue a consistent treatment regimen for all pain conditions. Pharmacogenomics would bring consistency to the subjective nature of pain and could revolutionize the field of pain management by providing personalized medical care tailored to each patient based on their gene variants. Additionally, pharmacogenomics offers a solution to the opioid crisis by identifying potentially opioid-vulnerable patients who could be recommended a nonopioid treatment for their pain condition. The integration of pharmacogenomics into clinical practice creates better and safer healthcare practices for patients. In this article, we provide a comprehensive history of pharmacogenomics and pain management, and focus on up to date information on the pharmacogenomics of pain management, describing genes involved in pain, genes that may reduce or guard against pain and discuss specific pain management drugs and their genetic correlations.

Eighteen-Year Trends in the Prevalence of, and Health Care Use for, Noncancer Pain in the United States: Data from the Medical Expenditure Panel Survey

We used data from the nationally representative Medical Expenditure Panel Survey to determine the 18-year trends in the overall rates of noncancer pain prevalence and pain-related interference, as well as in health care use attributable directly to pain management. The proportion of adults reporting painful health condition(s) increased from 32.9% (99.7% confidence interval [CI] = 31.6-34.2%;120 million adults) in 1997/1998 to 41.0% (99.7% CI = 39.2-42.4%; 178 million adults) in 2013/2014 (P_trend < .0001). Among adults with severe pain-related interference associated with their painful health condition(s), the use of strong opioids specifically for pain management more than doubled from 11.5% (99.7% CI = 9.6-13.4%) in 2001/2002 to 24.3% (99.7% CI = 21.3-27.3%) in 2013/2014 (P_trend < .0001). A smaller increase (P_interaction < .0001) in strong opioid use was seen in those with minimal pain-related interference: 1.2% (99.7% CI = 1.0-1.4%) in 2001/2002 to 2.3% (99.7% CI = 1.9-2.7%) in 2013/2014. Small but statistically significant decreases (P_trend < .0001) were seen in 1) the percentage of adults with painful health condition(s) who had ≥1 ambulatory office visit for their pain: 56.1% (99.7% CI = 54.2-58.0%) in 1997/1998 and 53.3% (99.7% CI = 51.4-55.4%) in 2013/2014; 2) the percentage who had ≥1 emergency room visit for their pain; 9.9% (99.7% CI = 8.6-11.2%) to 8.8% (99.7% CI = 7.9-9.7%); and 3) the percentage with ≥1 overnight hospitalization for their pain: 3.2% (99.7% CI = 2.6-4.0%) to 2.3% (99.7% CI = 1.8-2.8%). PERSPECTIVE: Our data illustrate changes in the management of painful health conditions over the last 2 decades in the United States. Strong opioid use remains high, especially in those with severe pain-related interference. Additional education of health care providers and the public concerning the risk/benefit ratio of opioids appears warranted.

Socioeconomic factors, psychological factors, and function in adults with chronic musculoskeletal pain from rural Nepal

Background

Both socioeconomic and psychological factors have been shown to predict patient function in samples of individuals with chronic pain in Western countries. However, little is known about their role as predictors of function in individuals with chronic pain from developing countries.

Purpose

The purpose of this study was to examine the associations between measures of socioeconomic factors (income, education) and psychological factors (catastrophizing and resilience) and measures of function in a sample of individuals with chronic pain from rural Nepal. In addition, we sought to evaluate the moderating effects of socioeconomic factors on the associations between the psychological variables and function.

Methods

We interviewed 143 adults with chronic musculoskeletal pain from rural areas of Nepal to assess income, education level, pain intensity, catastrophizing, resilience, physical function, and depression. We performed two regression analyses to evaluate the direct and unique effects of the socioeconomic and psychological variables and pain intensity as predictors of patient function, as well as the moderating influence of income, education level, and pain intensity on the associations between the psychological variables and function.

Results

Education and income both predicted physical function, but only income predicted depression. In addition, pain catastrophizing, but not resilience, evidenced a direct and significant independent association with depression. Neither catastrophizing nor resilience made independent and significant direct contributions to the prediction of physical function. The association between resilience and physical function was moderated by pain intensity and income, and income (but not education or pain intensity) moderated the associations between both 1) resilience and depression and 2) catastrophizing and depression.

Conclusion

The results suggest the possibility that cultural differences may influence the role that psychosocial factors play in chronic pain adjustment. These findings have important implications regarding how psychosocial pain interventions should be adapted by individuals in developing countries.

Can breast characteristics predict upper torso musculoskeletal pain?

BACKGROUND

Several studies have associated a large breast size with an increased prevalence and severity of musculoskeletal pain, particularly pain in the upper torso. Despite this evidence, no research has explored whether breast size or related characteristics are risk factors for upper torso musculoskeletal pain.

METHODS

A backward multiple regression analysis was performed to identify whether characteristics of the breasts and upper torso, as well as physical factors known to be associated with musculoskeletal pain, could predict musculoskeletal pain among a cohort of 378 Australian women aged 18 years and over who had a wide range of breast sizes.

FINDINGS

The model identified that breast volume, age and nipple-to-nipple distance predicted 23% of the variance in upper torso musculoskeletal pain reported by the participants.

INTERPRETATION

Women with a larger breast volume, lower age and a greater nipple-to-nipple distance were predicted to report a higher upper torso musculoskeletal pain score.

Clinical profile of persistent genito-pelvic postpartum pain

OBJECTIVE*: the primary aim was to describe the pain characteristics of persistent genito-pelvic postpartum pain (PPP) and compare these characteristics by mode of delivery. The secondary aim was to incorporate psychosocial variables into the conceptualization of PPP by exploring the relationship among postpartum depressive symptoms, fatigue, and PPP.

DESIGN

cross-sectional study design.

SETTING

online survey.

PARTICIPANTS

106 women recruited from the community who gave birth within twelve months prior to completing the survey.

MEASUREMENTS AND FINDINGS

questionnaire regarding sociodemographic information, pregnancy and childbirth variables, depressive symptoms (Edinburgh Postnatal Depression Scale), and fatigue (Fatigue Symptom Checklist). Women who were ≥3 months postpartum and indicated they were still experiencing any genito-pelvic pain from childbirth were provided questions about their current pain experience. Twenty-seven (25.5%) women were between 3-12 months postpartum and currently experiencing PPP. The intensity of pain was mild, and had multiple locations and triggers. Compared to women whose acute pain resolved after childbirth, women with PPP were more likely to have had a Caesarean section (15.2% versus 33.3%). Other birth-related (i.e., epidural/spinal anesthesia use during vaginal birth) and psychosocial variables (income) also differentiated women with PPP from women whose gentio-pelvic pain resolved. Postpartum fatigue independently predicted PPP (Odds ratio = 4.7), while postpartum depressive symptoms did not.

KEY CONCLUSIONS

PPP was quite prevalent in this sample, and while the intensity of pain was on average, mild, the pain was widespread in terms of location and triggers. Multiple biopsychosocial factors differentiated women with persistent postpartum pain from those women whose pain resolved.

IMPLICATIONS FOR PRACTICE

PPP is a common health concern for new mothers in the first year postpartum, and may be best addressed by health care professionals using a multidimensional approach, which focuses on the psychosocial aspects of pain.

ISPOG European Consensus Statement - chronic pelvic pain in women (short version)

To date there is no international guideline on chronic pelvic pain available that focuses on medical, psychosomatic and psychological diagnostics and treatment of this complicated disease pattern. In this paper, a European working group, which was established in October 2010, aims to bridge this gap. The working group decided to use the current German guideline as source text and to transform it into a European consensus statement by deleting parts that apply only to the conditions of the German health system. The literature search included papers published up to and including December 2010, using Medline search and by adding some new search terms. This manuscript reports the essential facts of the above-mentioned consensus statement. Within this article we use the term "psychosomatic" as the integrated concept of medical and psychosocial aspects of a disease.

MBMD coping styles and psychiatric indicators and response to a multidisciplinary pain treatment program

Psychosocial and personality factors are known to contribute to the maintenance of and recovery from chronic pain conditions but less is known about their influence on the efficacy of pain treatment programs. The purpose of the present study is to examine the ability of the Millon Behavioral Medicine Diagnostic (MBMD), a broadband measure of personality and psychosocial characteristics, to predict response to multidisciplinary pain treatment. 93 patients completed the MBMD, and ratings of current pain and average pain on an 11 point scale, prior to a multidisciplinary pain management program. Ratings of current and average pain were completed upon program completion. Participants were classified as "successful" or "unsuccessful" program completers based on pain reductions of ≥2 points. After program completion, 47 % of participants evidenced successful pain reductions. These successful participants had lower scores on depression and on coping style scales measuring introversive, inhibited, and dejected tendencies at baseline. Additionally, lower pre-treatment depression scores and lower scores on each of these coping style scales predicted lower pain ratings at discharge independent of educational level and pre-treatment pain ratings. The MBMD may be a useful tool to delineate patients who are likely to make significant treatment gains in intense, multidisciplinary pain treatment programs.

History of abuse and its relationship to pain experience and depression in women with chronic pelvic pain

OBJECTIVE

We sought to determine the relationship among a history of physical or sexual abuse, pain experience, and depressive symptoms among women with chronic pelvic pain (CPP).

STUDY DESIGN

This was a cross-sectional study of women who presented to a tertiary referral center for evaluation of CPP (N = 273). All participants completed standardized questionnaires to assess a history of physical or sexual abuse, pain severity, pain disability, and depressive symptoms. Subjects were grouped by abuse category and compared to CPP participants without history of abuse. Multinomial logistic regression models were used to determine the association between adolescent or adult and childhood physical or sexual abuse with pain intensity, pain-related disability, and depressive symptoms.

RESULTS

Logistic regression analyses indicated that, after controlling for age and education, none of the abuse categories was associated with pain severity. However, adolescent or adult sexual abuse predicted greater pain-related disability (odds ratio, 2.39; 95% confidence interval, 1.05-5.40), while both adolescent or adult physical and sexual abuse were associated with higher levels of depression (both P < .05). Level of education was significantly associated with pain intensity, pain disability, and depression.

CONCLUSION

For our sample of women with CPP, a history of abuse during childhood or adulthood was not associated with differences in pain intensity, but adolescent or adult sexual abuse was associated with greater pain-related disability. A history of physical abuse or sexual abuse appears to hold a stronger relationship with current depressive symptoms than pain experience for women with CPP. Educational achievement holds a robust relationship with pain morbidity and depression for this population.

The Impact of Socioeconomic and Anamnestic Characteristics on Quality of Life and Sexual Function in Women with Endometriosis

Purpose

The aim of this study is to evaluate the impact of sociodemographic and anamnestic characteristics of women with deep infiltrating endometriosis (DIE) on the quality of life and sexual function.

Methods

It is a prospective cohort study including 200 women with pre-operative clinical and ultrasound diagnosis of DIE. They completed a pre-operative questionnaire regarding sociodemographic and anamnestic characteristics, a sexual activity questionnaire (Sexual Health Outcomes in Women Questionnaire [SHOW-Q]) and a quality of life questionnaire (Short Form-36 Health Survey [SF-36]).

Results

The mean values obtained for the SF-36 (50.7 ± 21.1) and SHOW-Q (56.4 ± 21.1) questionnaire showed an impairment of quality of life and sexual function. Women with a history of previous surgery had significantly lower scores of SF-36 and SHOW-Q questionnaires than women without (p< 0.05). The increase of body mass index (BMI) was positively correlated with an improvement of sexual function (p = 0.008). Postsecondary education was significantly associated with a better quality of life (p = 0.001).

Conclusions

Patients with DIE have an impairment of quality of life and sexual function. Educational level, BMI and previous surgery may influence quality of life and sexual function of women affected by DIE.

The impact of endometriosis on quality of life in Hungary

Introduction: Endometriosis is one of the most common gynaecological diseases affecting 70 million women worldwide. Aim: The aims of this study were to determinate the diagnostic delay of endometriosis, to assess the effectiveness of surgical and combined therapy and to analyse the quality of life of women suffering from this disease. Method: Of the 240 patients with endometriosis enrolled in the study, 84 patients filled in a prospective as well as a retrospective questionnaire. Results: There was a 3.9 year delay from the onset of symptoms to the definitive diagnosis. Before therapy, 89% of the patients reported endometriosis related pain, while after therapy only 28% in the prospectively investigated months (p = 0.025). There was no significant difference between the outcome of surgical treatment alone and combined operative and medical therapy (p = 0.85). Reduced productivity at work was present in 47% of the patients and 40% of the patients reported impaired personal relationship, too. Endometriosis-associated symptoms generated 0.147 quality-adjusted life years per woman. Conclusions: This study is the first ever prospective survey to investigate the impact of endometriosis on the quality of life in Hungary. The results indicated a long diagnostic delay. Both surgical and combined therapies proved to be efficient. Endometriosis impaired health-related quality of life, but adequate therapy attenuated the severity of symptoms. Orv.

The medicalization of women's sexual pain

The medicalization of women's sexual problems under the overall rubric of female sexual dysfunction (FSD) has been thoroughly critiqued by feminist scholars, health practitioners, and sex therapists. However, there has been much less commentary on the medicalization of women's sexual pain-currently, a subset of an official FSD diagnosis. This article critically examines interdisciplinary understandings and ways of addressing sexual pain. It analyzes these frameworks in relation to feminist theories on medicalization, heteronormativity, and the reciprocal relationship between these two processes. We argue that many women who experience sexual pain have been eager for medicalization as a path to minimizing pain during sexual activity and reinstating normative heterosexual practices and identities. These goals have been lobbied for by patient advocacy groups and noted by professionals in the field. Although there are some clear benefits to this case for medicalization, there are also theoretical, personal, and political costs. Guided by a growing body of feminist theoretical and qualitative, empirical research on this topic, as well as the first author's personal experience of sexual pain, this article highlights some alternatives to medicalization and makes suggestions for change.

Pain as a global public health priority

BACKGROUND

Pain is an enormous problem globally. Estimates suggest that 20% of adults suffer from pain globally and 10% are newly diagnosed with chronic pain each year. Nevertheless, the problem of pain has primarily been regarded as a medical problem, and has been little addressed by the field of public health.

DISCUSSION

Despite the ubiquity of pain, whether acute, chronic or intermittent, public health scholars and practitioners have not addressed this issue as a public health problem. The importance of viewing pain through a public health lens allows one to understand pain as a multifaceted, interdisciplinary problem for which many of the causes are the social determinants of health. Addressing pain as a global public health issue will also aid in priority setting and formulating public health policy to address this problem, which, like most other chronic non-communicable diseases, is growing both in absolute numbers and in its inequitable distribution across the globe.

SUMMARY

The prevalence, incidence, and vast social and health consequences of global pain requires that the public health community give due attention to this issue. Doing so will mean that health care providers and public health professionals will have a more comprehensive understanding of pain and the appropriate public health and social policy responses to this problem.

Association of fibromyalgia characteristics in patients with non-metastatic breast cancer and the protective role of resilience

Cancer patients often complain about weakness, fatigue, and pain. The aim of this study was to assess the features of the fibromyalgia syndrome (FMS) characteristics in patients with non-metastatic breast cancer. The study group included 40 women whose age ranged from 40 to 70 years with Stages 0-3 breast cancer. The control group included 40 healthy women matched by age. A diagnosis of FMS was established based on medical history, physical examination, and the Fibromyalgia Impact Questionnaire (FIQ). Pain measures and functional factors were evaluated by the Brief Pain Inventory and the Sheehan Questionnaire. Resilience was assessed by Antanovsky's Sense of Coherence Questionnaire. Psychiatric disturbances were tested by the MINI Questionnaire and Hamilton questionnaires for depression and anxiety. The prevalence of chronic pain was higher in the study group. Statistically significant differences were also found between the group regarding pain, fatigue, and functional measures. The prevalence of depressive or anxious mood, measured by the Hamilton questionnaires, was strongly related to FMS characteristics reflected by FIQ scores (r = 0.79 between FIQ and the Hamilton Depression Index and r = 0.75 between FIQ and the Hamilton Anxiety Scale). The sense of coherence measure for these patients demonstrated an inverse correlation with pain, fatigue, and functional capability. Women with breast cancer tend to develop chronic widespread pain syndromes more often than do healthy women.

Moderators of the negative effects of catastrophizing in arthritis

OBJECTIVES

Pain is among the most frequently reported, bothersome, and disabling symptoms described by patients with rheumatoid arthritis (RA), and the experience of pain is partially shaped by catastrophizing, a set of cognitive and emotional pain-related processes. However, other variables may moderate catastrophizing's influence on the experience of pain. In this study, we investigated a variety of factors that might buffer or magnify catastrophizing's deleterious consequences among patients with RA.

METHODS

A total of 185 RA patients were surveyed to determine levels of catastrophizing, pain, general psychological distress, and physical functioning.

RESULTS

Catastrophizing was associated with increased pain severity and psychological distress, and with poorer physical functioning. Some of these relationships were significantly moderated by education and social functioning; among RA patients with above-average social functioning and a college education, minimal relationships of catastrophizing with pain and distress symptoms were observed, while these associations were highly significant (Ps < 0.001) among patients with lower levels of education or social functioning.

CONCLUSIONS

Collectively, educational achievement and positive social interactions may protect against some of the deleterious effects of catastrophizing. The design of future interventions to reduce catastrophizing or ameliorate its impact on pain outcomes may benefit from further study of these subgroups of patients.

Endurance and contest: women's narratives of endometriosis

Endometriosis is an often painful medical condition in which, in response to hormones associated with the menstrual cycle, the uterine lining grows in the peritoneum and other organs, bleeding into the surrounding organs and tissues. Diagnosis is not always straightforward, and women and health professionals alike may have difficulties recognizing period pain as a sign of anomaly, considering it instead as an inevitable part of menstruation. This article describes the illness narratives of Australian women with endometriosis, drawing on data collected during a study conducted in Victoria in 2004-5. Thirty women (aged 20-78 years) from various socio-demographic backgrounds participated in in-depth interviews. We explore the influence of socio-demographic background and social and family norms on women's illness narratives of endurance and contest. Narratives of endurance are characterized by the normalization of period pain by young women, their families and health professionals, and, with diagnosis, long-term exposure to biomedical treatments. In contrast, narratives of contest are dominated by how women's subjective experience is challenged by doctors, their requirements for a patient-centered approach, and their desire to have access to complementary treatments.

The association between neighbourhood socio-economic status and the onset of chronic widespread pain: results from the EPIFUND study

Background

Cross-sectional studies have reported an inverse relationship between socio-economic status and the prevalence of chronic widespread pain (CWP). However, the extent to which this relationship is explained by psychological factors is unknown. The aim of this study was to examine the hypothesis that socio-economic status predicts the onset of CWP but that this relationship would be explained by psychological factors.

Methods

Subjects from three diverse socio-economic areas were recruited into a population-based prospective survey of pain. Subjects completed a questionnaire at baseline that assessed pain status and psychological factors and occupation. Fifteen months later subjects completed a follow-up questionnaire which assessed pain status.

Results

A total of 3489 subjects were free of CWP at baseline and eligible for follow-up, of whom 2782 (79.7%) participated. Of those, 281 (10%) subjects were classified as having new CWP. Logistic regression analysis revealed that compared to subjects from the most affluent socio-economic area, those from the moderate and least affluent areas were respectively, 1.47 (95% CI: 1.08–2.01) and 1.35 (95% CI: 1.00–1.82) times more likely to have new CWP. However, in a stepwise multivariate logistic regression analysis, controlling for psychological factors, the relationship between new onset CWP and socio-economic status was no longer evident.

Conclusions

This study has demonstrated that socio-economic status is related to new onset CWP, but the association is explained by psychological factors. Understanding the factors underlying the association between socio-economic status and pain should help to design intervention strategies which may reduce the burden of chronic pain in identified high risk population groups.

Epidemiology of chronic musculoskeletal pain

The rate of musculoskeletal pain in adolescent and adult populations is examined, with a focus on three commonly reported pain disorders: shoulder pain, low back pain and fibromyalgia/chronic widespread pain. There is a paucity of data on musculoskeletal pain in adolescent populations. Those studies available suggest that pain is common, although the actual rates are unclear. This is probably due to differences in study methodologies and populations. Pain is commonly reported among adult populations, with almost one fifth reporting widespread pain, one third shoulder pain, and up to one half reporting low back pain in a 1-month period. The prevalence of pain varies within specific population subgroups; group factors (including socioeconomic status, ethnicity and race) and individual factors (smoking, diet, and psychological status) are all associated with the reporting of musculoskeletal pain. However, the precise nature of these relationships, and particularly the mechanisms of association, are unclear and require further investigation.

Catastrophizing, Pain, and Social Adjustment in Scleroderma: Relationships With Educational Level

OBJECTIVES

Low educational attainment is related to numerous adverse health outcomes, and some evidence suggests that psychosocial variables may mediate education's effects. Moreover, the relationship between psychosocial functioning and health-related outcomes may be moderated by educational level, with individuals lower in formal education being more susceptible to the deleterious effects of negative cognitive and affective states. The present study sought to characterize such interrelationships between educational level and pain-related catastrophizing.

METHODS

We investigated the association of self-reported educational level with pain and social disability, we evaluated catastrophizing's potential mediating role in those associations, and we also investigated education as a moderator of catastrophizing's effects on pain and social disability in a sample of patients with scleroderma, a frequently painful autoimmune disorder.

RESULTS

First, education-related differences in pain report were accounted for by catastrophizing and depression. Second, after controlling for demographic factors, disease severity, and depressive symptoms, education moderated the relationship between catastrophizing, pain affect, and social function. Specifically, catastrophizing was more highly associated with greater reporting of affective pain among those with less formal education. In addition, catastrophizing inversely correlated with social disruption among individuals with less formal education.

DISCUSSION

Collectively, study findings support multiple models of interaction between education and pain-related cognitive/affective functioning, though in both mediational and moderational analyses, lower levels of formal education act as a risk factor for adverse pain-related outcomes.

Sexual functioning in women with chronic pelvic pain: the impact of depression, support, and abuse

Many studies have documented associations between sexual functioning, depression, experiences of childhood sexual abuse, relationship support, and chronic pelvic pain, but none have addressed the interrelationships among all of these variables in a unified model. The aim of this preliminary study was to construct an integrative model predicting sexual functioning for women with chronic pelvic pain. Sixty-three women with chronic pelvic pain completed measures of sexual functioning for use as the criterion variable, and measures of the impact of chronic pain, depression, experiences of sexual abuse, and relationship support as predictors. The primary finding was that depression mediated the effects of child sexual abuse and partially mediated the effects of relationship support on sexual behavior and satisfaction with the sexual relationship. In addition to its indirect relationship through depression, relationship support also independently predicted sexual function. Thus, in this nonclinical sample, the effects of child sexual abuse on sexual function depended on the extent of depressive symptoms, while the influence of relationship support depended in part on depression.

Physical and emotional functioning of adult patients with chronic abdominal pain: Comparison with patients with chronic back pain

Adults with chronic abdominal pain remain a poorly defined population, despite the debilitation and depression associated with this therapeutically challenging condition. This study compared patients with chronic abdominal pain with an empirically well-known group of patients with chronic pain (back pain) to investigate similarities and differences in their physical and mental functioning. This retrospective, cross-sectional study included 136 patients with abdominal pain and 364 patients with back pain seen in a comprehensive pain rehabilitation center. Patients' functioning was assessed with the Short Form-36 Health Survey, Multidimensional Pain Inventory, Center for Epidemiological Studies-Depression scale, and Coping Strategies Questionnaire-Catastrophizing subscale. Both the abdominal and back pain patients reported long-standing and severe pain, numerous surgery procedures, poor functioning, and high prevalence of depression. When age, education, and marital status were controlled for, analyses showed that although patients with abdominal pain reported significantly better physical functioning than patients with back pain (P < .001), their overall health perception was significantly poorer (P < .001). Although less prevalent, it is clear that patients with chronic abdominal pain exhibit poor functioning and prevalence of depression that are comparable to patients with chronic back pain. This study also suggests distinct characteristics that are vital to consider for effective treatment of this chronic pain population.

PERSPECTIVE

As a result of being an overlooked and poorly defined population, adults with chronic abdominal pain might not receive adequate pain management treatment. Learning more about the physical and emotional functioning of patients with long-standing abdominal pain can increase recognition of the needs of and improve treatment for this population.
