Chronic pain is associated with increased health care use among community-dwelling older adults in Brazil: the Pain in the Elderly (PAINEL) Study

Prevalence of chronic pain in Brazil: A systematic review and meta-analysis

OBJECTIVE

This review synthesized existing studies on the prevalence of chronic pain in Brazil and its associated factors to produce a recent estimation to guide public health politics.

METHODS

A search was carried out in the Ovid Medline, Embase, Web of Science, and BVS Regional/Lilacs databases to identify population-based cross-sectional studies from 2005 to 2020, which reported the prevalence of benign chronic pain in Brazil (more than three months). The risk of bias was assessed using design, sample size determination, and random selection as essential issues. Pooled prevalence estimates were calculated for chronic pain in the general and elderly populations. The protocol was registered on Prospero (CRD42021249678).

RESULTS

Of the 682 identified, 15 macheted the authors' inclusion criteria. Chronic pain prevalence in the general adult population ranged from 23.02% to 41.4% (pooled estimate 35.70%, 95% Cis 30.42 to 41.17) and was described as moderate to intense. It was associated with female sex, old age, lower education, intense professional activity, excessive alcohol consumption, smoking, central obesity, mood disorder, and sedentarism. The Southeastern and Southern regions presented a higher prevalence. The prevalence in the elderly population ranged from 29.3% to 76.2% (pooled estimate 47.32%, 95% Cis 33.73 to 61.11). In addition, this population visited doctors more frequently, had more sleep disorders, and was more dependent on daily living activities. Almost fifty percent of both populations with chronic pain reported pain-induced disability.

CONCLUSION

Chronic Pain is highly prevalent in Brazil and associated with significant distress, disability, and poorly controlled.

"With your age, what do you expect?": Ageism and healthcare of older adults in Spain

INTRODUCTION

Ageism could influence the relationship between older patients' meeting needs and healthcare professionals' answers.

AIMS

To highlight the experience of older adults with healthcare systems, how they perceive ageism from their healthcare providers, and to explore the relationship between perceived ageism and self-perception of aging (SPA).

METHODS

We conducted an exploratory qualitative study. The participants were 14 women over 65 who lived alone in their homes.

RESULTS

Professional responses ignored the expression of preferences of the older patients and excluded them from decision-making processes. These answers influenced older patients' use of health services. Moreover, the negative aspects predominated in a SPA influenced by the internalization of stereotypes and a relationship weighed down by ageist behaviors on the part of health professionals.

CONCLUSION

Explicit situations of ageism influence an imbalance in power relations between older patients and healthcare professionals, a misuse of health services, and a negative SPA.

Anxiety, Depression, Chronic Pain, and Quality of Life Among Older Adults in Rural China: An Observational, Cross-Sectional, Multi-Center Study

PURPOSE

To determine the incidence of anxiety and depression and examine their cross-sectional associations with chronic pain and quality of life among older adults in rural China.

DESIGN

Observational, multi-center, cross-sectional study.

METHODS

A structured, self-report questionnaire was administered. Descriptive statistics analysis and stepwise multiple linear regression analysis were performed.

FINDINGS

244 participants (female: 47.1%) filled out the questionnaires. 87 (35.7%) had symptoms of anxiety and 123 (50.4%) had symptoms of depression. The sensory pain descriptor, affective pain descriptor, physical component summary, and mental component summary significantly influenced symptoms of anxiety while affective pain descriptor, physical component summary, and mental component summary significantly influenced symptoms of depression.

CONCLUSION

Subjective pain experiences and QoL, including physical and mental domains, are strongly related to symptoms of anxiety and depression among older adults in rural China.

CLINICAL EVIDENCE

Interventions that highlight subjective pain experiences and QoL may help to relieve symptoms of anxiety and depression in older adults.

Dose-response associations of clinical markers of obesity and duration of exposure to excess weight with chronic musculoskeletal pain: cross-sectional analysis at baseline of ELSA-Brasil Musculoskeletal cohort

The objective of this study is to investigate the association of clinical markers of obesity and weight trajectories with chronic musculoskeletal pain (CMP). This is a cross-sectional study using baseline data from ELSA-Brasil MSK cohort. CMP was evaluated at nine body sites (neck, shoulders, upper back, elbows, lower back, wrists/hands, hips/thighs, knees, ankles/feet), and defined as pain lasting > 6 months in the past year. General and abdominal obesity levels were classified according to accepted cut-offs for body mass index (BMI), waist circumference (WC) and waist-height ratio (WHtR). Binomial and multinomial logistic regressions tested for associations with CMP at any site, at ≥ 3 sites (multisite) and in upper + lower limbs + axial skeleton (generalized). A total of 2899 participants (mean age 56.0 ± 8.93) were included, 55.0% reported CMP, 19.1% had multisite, and 10.3% had generalized CMP. After adjustments for sex, age, education, physical activity and depressive symptoms, nearly all the investigated markers of obesity were associated with any CMP, multisite and generalized CMP, with strongest associations being observed for general obesity level II/III: OR 2.08 (95% CI 1.45-2.99), OR 3.19 (95% CI 2.06-4.94) and OR 3.65 (2.18-6.11), respectively. Having excess weight currently or both at age 20 and currently was also associated with all CMP presentations. Associations of greater magnitude were consistently observed at higher obesity levels and longer exposures to excess weight (dose-response). These results may support the contribution of obesity-derived mechanical and inflammatory mechanisms of CMP, and indicate a role for the accumulation of exposure to excess weight across the adult life course.

Prevalence of pain and associated factors in Brazilian civil servants: an introductory analysis using baseline data from the ELSA-Brasil cohort

Supplemental Digital Content is Available in the Text.

Introduction:

In Brazil, the prevalence and costs of pain will increase substantially with population ageing. Understanding of pain epidemiology is needed for the development of health care policies that can minimize this projected burden.

Objective:

To investigate the prevalence of pain and associated factors at baseline of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).

Methods:

Data were collected in public institutions of higher education/research (2008–2010). Pain in the past 30 days and pain attributed to psychological distress (“with psychological attributions”—PPA) were evaluated by the Clinical Interview Schedule-Revised (CIS-R). The independent t-test and χ² test investigated associations between sociodemographic/clinical factors and each pain episode. Multivariable analyses including age, sex, leisure-time physical activity, depression, and arthritis/rheumatism, and factors showing univariate associations at the P < 0.10 level, were performed.

Results:

Fifteen thousand ninety-five civil servants were included (52.1 ± 9.1 years, 54.4% female). The prevalence of any pain was 62.4% (95% confidence interval 61.6%–63.2%), and of PPA was 22.8% (95% confidence interval 22.2%–23.5%). Factors associated with any pain and PPA in multivariable analyses included age (odds ratio [OR] 0.97), female sex (OR 1.86–2.01), moderate and vigorous leisure-time physical activity (OR 0.60–0.84), excessive drinking (OR 0.68–0.83), depressive symptoms (OR 1.28–1.96), anxiety symptoms (OR 1.63–2.45), sleep disturbance (OR 1.62–1.79), and arthritis/rheumatism (OR 1.32–2.18). Nonroutine nonmanual occupation (manual occupation as reference), body mass index, and smoking were independently associated with either any pain or PPA.

Conclusion:

This study provided preliminary information on the epidemiology of pain at baseline of the largest Latin American cohort on chronic noncommunicable diseases.
