Gender Differences in Pain Risk in Old Age: Magnitude and Contributors

The mediating role of depressive symptoms among Turkish population related to gender and low back pain: evidence from a national health survey

BACKGROUND

Low back pain (LBP), though non-life-threatening, burdens healthcare with treatment expenses and work hours lost. Globally, 70-84% experience it, with risk factors tied to societal structure, income, and living conditions, making it a leading cause of disability.

METHODS

This study utilized data from the 2019 Türkiye Health Survey, which consisted of 17,084 individuals aged 15 and above. Our study focused on investigating the factors related to low back pain through a cross-sectional analysis. To analyze these factors, we employed binary multivariate logistic regression. Additionally, we conducted post-hoc analyses to assess the potential mediating effect of depressive symptoms on the relationship between low back pain and gender.

RESULTS

We found that 31.9% of the population experienced low back pain, with women being 58% more likely [aOR = 1.58; 95% CI (1.45-1.73)] than men to report symptoms. Individuals aged 55 + years old had a 90% [aOR = 1.90; 95% CI (1.61-2.23)] chance of experiencing low back pain, indicating an age-related increase. In the general population, having depressive symptoms was 2.49 [95% CI (2.23-2.78)] times more likely associated with low back pain. Our mediation analysis showed that gender (i.e., women vs. men), indicated by direct effects with β-estimates e = 0.78, predicted the likelihood of low back pain. Additionally, the relationship between gender and low back pain, mediated through a history of depressive symptoms, had a significant total indirect effect (i.e., β-estimate given as e = 0.49). Specifically, a history of depressive symptoms accounted for 17.86% [95% CI (9.67-20.10)] of the association between women having a higher likelihood of low back pain compared to men.

CONCLUSION

We observed that a higher likelihood of low back pain associated with gender and aging. Additionally, BMI served as a significant predictor, particularly in adults. Depression mediated the association between gender and low back pain. Acknowledging these associations may help identify and address contributing factors to LBP, potentially increasing awareness and alleviating the burden. Policymakers and healthcare professionals may consider these findings when developing prevention and treatment programs for low back pain.

Effect of gender on the evolution of pain and quality of life after treatment of symptomatic vertebral fragility fractures

The evolution of pain and quality of life after a symptomatic vertebral fracture differs according to patient gender, with a worse evolution in women independently of the treatment received.

PURPOSE

In a previous randomized clinical study comparing the effect of vertebroplasty (VP) vs. conservative therapy (CT) on pain evolution and quality of life (QoL) of patients with symptomatic vertebral fractures (VF), we observed the development of chronic back pain in 23% of subjects, independently of the therapy received. This study analyses the effect of gender on the evolution of pain and QoL in these subjects.

METHODS

118/125 randomized patients (27 males/91 females) with recent symptomatic VFs were evaluated. All received a standardized analgesic and antiosteoporotic format of treatment. Pain and QoL were evaluated by VAS and Qualeffo-41, respectively, at baseline, at 2 weeks and 2 and 6 months. We compared pain evolution and QoL after treatment (CT vs. VP) according to gender, and analysed factors including age, time of evolution, treatment received, baseline VAS, previous VFs (total and recent), incidental VFs, lumbar and femoral T-scores, and analgesic and antiosteoporotic treatment.

RESULTS

At baseline, there were no differences in age (males 74.8 ± 11.2 vs. females:73.2 ± 8.7 years), time of evolution, number of VFs (males:3.8 ± 2.4 vs. females: 3.1 ± 2.4), treatment received (VP, males:59%, females:45%), lumbar or femoral T-score, baseline VAS (males:6.8 ± 2.1 vs. females:6.8 ± 2.2) or Qualeffo score (males:52.2 ± 24.4 vs. females:59.7 ± 20.6). Pain and QoL evolution differed according to gender, being better in males. These differences were significant after two months independently of the treatment and the development of incidental VF during follow-up.

CONCLUSIONS

Pain and QoL evolution after a symptomatic VF differs according to gender, with a worse evolution in women independently of the treatment received.

Prevalence of Chronic Pain Among People with Dementia: A Nationwide Study Using French Administrative Data

OBJECTIVE

Alzheimer's disease or Related Dementia (ADRD) is known to disturb pain perception and reduce the ability to report it, resulting in underestimation by practitioners and sub-optimal medical management. The aim of this study was to estimate the prevalence of all types of CP among people with ADRD.

DESIGN

Nationwide cross-sectional study.

SETTINGS

French community-dwelling and nursing home residents.

PARTICIPANTS

People with ADRD, >40 years old, treated with cholinesterase inhibitors or memantine, or with a diagnosis/long-term illness of ADRD and matched with a comparison sample.

SETTINGS

French community-dwelling and nursing home residents.

PARTICIPANTS

People with ADRD, >40 years old, treated with cognitive stimulants (cholinesterase inhibitors and memantine) or with a diagnosis/long-term illness of ADRD and matched with a comparison sample (non-ADRD).

MEASUREMENTS

The capture-recapture method was performed to provide estimates of the prevalence of CP. People treated with analgesic drugs for ≥6 months consecutively or with a medical diagnosis of CP (ICD-10 codes) or referred to a pain center were considered as having CP.

RESULTS

A total of 48,288 individuals were included, of which 16,096 had ADRD and 32,192 without ADRD. The estimated prevalence of CP in people with ADRD was from 57.7% [52.9;63.3] to 57.9%[53.0;63.9], and slightly higher than the non-ADRD sample (from 49.9%[47.0;53.2] to 50.4%[47.3;53.9], p <0.001).

CONCLUSIONS

The prevalence of CP among people living with ADRD was at least the same as or better than individuals without ADRD. This result should alert practitioners' attention to the need for effective pain assessment and management in this population who has difficulties to express and feel pain.

The bidirectional association between chronic musculoskeletal pain and sleep-related problems: a systematic review and meta-analysis

OBJECTIVES

This systematic review and meta-analysis synthesizes the evidence on prospective bidirectional associations between sleep-related problems (SRP) and chronic musculoskeletal pain (CMP).

METHODS

A literature search for cohort studies available in the PubMed, Scopus, Web of Science, PsycINFO and Cochrane Library databases as of 19 July 2022 was performed. Pooled odds ratios and effect sizes were calculated through random effects meta-analysis. Subgroup and meta-regression analyses were performed to explore differences by follow-up time, proportion of each sex and mean age. The Meta-analysis Of Observational Studies in Epidemiology guidelines were strictly followed.

RESULTS

Twenty studies with a total of 208 190 adults (aged 34.4-71.7 years) were included, with 17 of them being used in the meta-analysis. Individuals with SRP at baseline had a 1.79-fold higher incidence (odds ratio [OR] = 1.79; 95% CI: 1.55, 2.08; I2 = 84.7%; P < 0.001) and a 2.04-fold higher persistence (OR = 2.04; 95% CI: 1.42, 2.94; I2 = 88.5%; P < 0.005) of CMP than those without SRP. In the subgroup analysis of the association between SRP and CMP, the longer the follow-up time of the studies, the higher the heterogeneity between them. In the corresponding meta-regression, no significant effect was observed for follow-up time, sex proportion or age. Individuals with CMP at baseline had a 2.02-fold higher incidence of SRP (OR = 2.02; 95% CI: 1.62, 2.53; I2 = 90.0%; P < 0.001) than those without CMP.

CONCLUSION

This study provides robust evidence concerning the longitudinal association between SRP and incidence-persistence of CMP in adults. In addition, the available prospective studies support the existence of a bidirectional relationship between CMP and SRP.

Examining the Association of Pain and Pain Frequency With Self-Reported Difficulty in Activities of Daily Living and Instrumental Activities of Daily Living Among Community-Dwelling Older Adults: Findings From the Longitudinal Aging Study in India

OBJECTIVES

We examined the prevalence and associations of self-reported difficulty in activities of daily living (ADL) and instrumental activities of daily living (IADL) with pain among community-dwelling older adults in India. We also explored the interaction effects of age and sex in these associations.

METHODS

We used the Longitudinal Ageing Study in India (LASI) Wave 1 data (2017-2018). Our unweighted sample included 31,464 older adults aged 60 years and above. Outcome measures were having difficulty in at least 1 ADL/IADL. We conducted multivariable logistic regression analyses to examine the association of pain with functional difficulties controlling for selected variables.

RESULTS

A total of 23.8% of older adults reported ADL and 48.4% reported IADL difficulty. Among older adults who reported pain, 33.1% reported difficulty in ADL and 57.1% reported difficulty in IADL. The adjusted odds ratio (aOR) for ADL was 1.83 (confidence interval [CI]: 1.70-1.96) and for IADL was 1.43 (CI: 1.35-1.51) when respondents reported pain compared with those without pain. Older adults who reported frequent pain had 2.28 and 1.67 times higher odds of ADL (aOR: 2.28; CI: 2.07-2.50) and IADL difficulty (aOR: 1.67; CI: 1.53-1.82) compared with those with no pain. Additionally, age and sex of the respondents significantly moderated the associations of pain and difficulty in ADL and IADL.

DISCUSSION

Given the higher prevalence and likelihood of functional difficulties among older Indian adults who experienced frequent pain, interventions to mitigate pain in this vulnerable population are needed to ensure active and healthy aging.

Socioeconomic and sex inequalities in chronic pain: A population-based cross-sectional study

OBJECTIVE

We investigated the impact of socioeconomic inequalities on chronic pain of older adults according to sex.

MATERIALS AND METHODS

This population-based cross-sectional study used survey data from the 2015 cohort of the SABE Study (Saúde, Bem-estar e Envelhecimento), Brazil. Socioeconomic status was examined at individual level (educational attainment, financial independence, and race/skin color) and contextual level (Human Development Index). We analyzed the association between variables using the chi-square test and the Rao & Scott correction. Logistic regression models were adjusted for risk factors.

RESULTS

The study comprised 1,207 older adults representing 1,365,514 residents 60≥ years of age in the city of São Paulo. Chronic pain was more frequent in females (27.2%) than in males (14.5%) (p<0.001). Females evidenced the worst self-perception of pain, especially those of the most vulnerable socioeconomic strata. Social inequalities impacted chronic pain in different ways between sexes. Among females, unfavorable living conditions (OR = 1.59; 95%CI 1.07; 2,37) and Blacks/Browns females were most likely to have chronic pain (OR = 1.32; 95%CI 1.01; 1.74). Among males, only the individual aspects were significant for the occurrence of chronic pain, such as low educational attainment (OR = 1.88; 95%CI 1.16; 3.04) and insufficient income (OR = 1.63; 95%CI 1.01; 2.62).

DISCUSSION

The potential for inequality was greater for females than for males reflecting structural factors inherent in a highly unequal society. Conclusions: Equity-oriented health policies are critical to preventing pain in human aging.

Social aging trajectories are sex-specific, sensitive to adolescent stress, and most robustly revealed during social tests with familiar stimuli

Social networks and support are integral to health and wellness across the lifespan, and social engagement may be particularly important during aging. However, social behavior and social cognition decline naturally during aging across species. Social behaviors are in part supported by the 'reward' circuitry, a network of brain regions that develops during adolescence. We published that male and female rats undergo adolescent social development during sex-specific periods, pre-early adolescence in females and early-mid adolescence males. Although males and females have highly dimorphic development, expression, and valuation of social behaviors, there is relatively little data indicating whether social aging is the same or different between the sexes. Thus, we sought to test two hypotheses: (1) natural social aging will be sex-speciifc, and (2) social isolation stress restricted to sex-specific adolescent critical periods for social development would impact social aging in sex-specific ways. To do this, we bred male and female rats in-house, and divided them randomly to receive either social isolation for one week during each sex's respective critical period, or no manipulation. We followed their social aging trajectory with a battery of five tests at 3, 7, and 11 months of age. We observed clear social aging signatures in all tests administered, but sex differences in natural social aging were most robustly observed when a familiar social stimulus was included in the test. We also observed that adolescent isolation did impact social behavior, in both age-independent and age-dependent ways, that were entirely sex-specific. Please note, this preprint will not be pushed further to publication (by me, AMK), as I am leaving academia. So, it's going to be written more conversationally.

Multimodal Interventions to Improve the Management of Chronic Non-Malignant Pain in Primary Care Using Participatory Research

BACKGROUND

The use of diverse therapies combined with a multidisciplinary approach and prevention initiatives for patients with chronic non-malignant pain (CNMP) can improve health and have a positive impact on psychotropic drug use and the self-management of pain.

PURPOSE

This purpose of this study has been two-fold: to conduct a literature review with a view to selecting best evidence recommendations for CNMP and to prioritize self-care recommendations using a participatory methodology for the analysis and selection of interventions.

METHODS

A qualitative, descriptive, and documentary method based on participatory action research was used.

FINDINGS

Based on the study results, a multimodal psychosocial intervention program has been designed for CNMP that includes psychoeducational therapy, pharmacological therapy, physical exercise, and health assets.

DISCUSSION

The findings are consistent with previous studies underlining the need to invest in resources for the management of CNMP, including strategies for good differential diagnoses and pharmacological treatments combined with non-pharmacological treatments to confer greater well-being for people living with pain who want to participate in their own recovery.

Changes in Health Behaviors, Mental and Physical Health among Older Adults under Severe Lockdown Restrictions during the COVID-19 Pandemic in Spain

We used data from 3041 participants in four cohorts of community-dwelling individuals aged ≥65 years in Spain collected through a pre-pandemic face-to-face interview and a telephone interview conducted between weeks 7 to 15 after the beginning of the COVID-19 lockdown. On average, the confinement was not associated with a deterioration in lifestyle risk factors (smoking, alcohol intake, diet, or weight), except for a decreased physical activity and increased sedentary time, which reversed with the end of confinement. However, chronic pain worsened, and moderate declines in mental health, that did not seem to reverse after restrictions were lifted, were observed. Males, older adults with greater social isolation or greater feelings of loneliness, those with poorer housing conditions, as well as those with a higher prevalence of chronic morbidities were at increased risk of developing unhealthier lifestyles or mental health declines with confinement. On the other hand, previously having a greater adherence to the Mediterranean diet and doing more physical activity protected older adults from developing unhealthier lifestyles with confinement. If another lockdown were imposed during this or future pandemics, public health programs should specially address the needs of older individuals with male sex, greater social isolation, sub-optimal housing conditions, and chronic morbidities because of their greater vulnerability to the enacted movement restrictions.

Opioid painkiller dependence in a sample of elderly medical inpatients

BACKGROUND

Over the past few years, there has been a growing concern about prescription opioid misuse and dependence in the elderly. Our study aimed to investigate the prevalence of previous and current prescription opioid dependence among elderly medical inpatients recruited from a large German hospital.

METHODS

This cross-sectional study analyzed a cohort of inpatients aged 65 years and older who were assessed with a structured clinical interview. Levels of past and current dependence on opioids benzodiazepines, hypnotics, and non-opioid analgesics were assessed.

RESULTS

Of 2108 elderly inpatients admitted to the hospital during a 6-month period, 400 fulfilled the inclusion criteria and agreed to participate to the survey. Among these 400 subjects, 43 (10.8%) presented with a dependence on opioid analgesics, including 41 with current dependence and 22 (51.2%) with a de novo condition. Addiction severity was considered mild in 65.1% of cases and severe in 11.6% of cases. Tilidine and oxycodone were the most typically reported molecules.

CONCLUSIONS

Further research is warranted, to better understand the possible risk factors of prescription drug misuse, abuse, and addiction in this vulnerable population. Clinicians should be updated and informed regarding both prescription medication misuse potential and safe prescribing practices in the elderly.

Pain Characteristics, Cardiovascular Risk Factors, and Cardiovascular Disease

BACKGROUND

There is unclear evidence that chronic pain may increase the risk of cardiovascular disease (CVD) incidence and mortality. This work evaluated the association between chronic pain, incidence of CVD and changes in CVD risk factors.

METHODS

Cohort of 1091 community-dwelling individuals ≥60years, free from CVD at baseline, followed up for 6 years. Data on psychosocial factors and CVD risk factors was obtained through validated questionnaires and laboratory measurements. A pain scale ranging from 0 (no pain) to 6 (worst pain) was created according to pain frequency, location and intensity.

RESULTS

The cumulative incidence of CVD was 4.2% at 3 years, and 7.7% at 5-years of follow-up. Compared to individuals without pain in the first 3 years (2012-2015), those with maintained scores ≥2 showed a mean reduction of 3.57 (-5.77,-1.37) METs-h/week in recreational physical activity; a 0.38-point (0.04,0.73) increase in psychological distress; and a 1.79 (1.03,3.11) higher odds of poor sleep. These associations held in the second follow-up period, when individuals with maintained pain also worsened their diet quality. A 1-point increase in the pain scale in 2012 was associated with a 1.21 (1.03,1.42) and 1.18 (0.97,1.44) increased CVD incidence in 2015 and 2017, respectively; none of the studied factors mediated this relationship.

CONCLUSIONS

Older adults with chronic pain show important reductions in recreational physical activity and deterioration in mental health, sleep and diet quality, which may well aggravate pain. Future studies should evaluate whether these factors mediate the increased risk of CVD observed in older adults with chronic pain.

Predictors of Mental Health Status among Older United States Adults with Pain

Poor mental health is common among older adults with pain, resulting in high economic burden and impaired quality of life. This retrospective, cross-sectional database study aimed to identify characteristics associated with good mental health status among United States (US) adults aged ≥50 years with self-reported pain in the last four weeks using a weighted sample of 2017 Medical Expenditure Panel Survey data. Hierarchical multivariable logistic regression models were used to identify statistically significant predictors of good (versus poor) perceived mental health status. From a weighted population of 57,074,842 individuals, 85.5% (95% confidence interval (CI) = 84.4%, 86.7%) had good perceived mental health. Good mental health was associated most strongly with physical health status (adjusted odds ratio (AOR) = 9.216, 95% CI = 7.044, 12.058). Employed individuals were 1.7 times more likely to report good mental health versus unemployed (AOR = 1.715, 95% CI = 1.199, 2.452). Individuals who had completed less than high school education (AOR = 0.750, 95% CI = 0.569, 0.987) or who reported having a limitation (AOR = 0.513, 95% CI = 0.384, 0.684) were less likely to report good mental health. These key characteristics can be utilized to predict mental health status, which may be investigated to better manage concurrent pain and poor mental health.
