Prevalence of pain and use of prescription opioids among older adults: results from the Brazilian Longitudinal Study of Aging (ELSI-Brazil).

Background: Pain has a significant impact on people's quality of life. The use of prescription opioids to treat pain is associated with an increased risk of opioid use disorders and overdose death. We measured the prevalence of recurrent pain, prescription opioid use, and associations between chronic conditions and prescription opioid use among Brazilian older adults. Methods: We used data from the first population-based longitudinal study of aging in Brazil (ELSI-Brazil), 2019-2020 (mean age = 63.3; 54.4% female). Outcomes were: (1) experience of recurrent pain and (2) use of opioid analgesics in the past three months among those who experience pain. Exposures included selected health conditions, history of falls, and hospitalizations. Findings: Prevalence of pain (n = 9234) was 36.9% (95% CI: 32.6-41.1). Pain was reported more frequently by female participants, low-income individuals, and those with a previous diagnosis of arthritis, chronic back pain, depressive symptoms, history of falls, and hospitalizations. Prevalence of opioid use among those reporting pain (n = 3350) was 30% (95% CI: 23.1-38.0). Prevalence of opioid use was higher among female and single individuals. In adjusted models, arthritis, chronic back pain, and presence of depressive symptoms were associated with prescription opioid use. Interpretation: Prescription opioid use was reported by a sizable portion of the older adults who suffer from pain in Brazil. In a context of growing consumption of prescription opioids, opioid misuse has the potential to increase in the future. Surveillance of prescription opioid use is critical to prevent their harmful consequences. Funding: ELSI-Brazil was funded by the Brazilian Ministry of Health.

[Longitudinal association between social capital and functional disability in a cohort of community dwelling older adults]. / Associação longitudinal entre capital social e incapacidade funcional em uma coorte de idosos residentes em comunidade.

This study aimed to investigate the association between social capital and functional disability, based on a longitudinal perspective, using data from the cohort of older adults from Bambuí, Minas Gerais State, Brazil. The baseline of this study was composed of all surviving and disability-free - up until the seventh year of follow-up (2004) - older adults who were followed up until 2011. The outcome variable was functional disability for basic activities of daily living (ADL) and instrumental activities of daily living (IADL), separately analyzed. Social capital was the exposure of interest, measured through its cognitive (cohesion and social support) and structural (social participation and satisfaction with the neighborhood) components. Sociodemographic variables, health conditions, and lifestyle habits were used for adjustment purposes, and the occurrence of death was considered a competitive event. The hypothesis of association between social capital and functional disability was tested using the competing risk model, which provides hazard ratios (HR) and a 95% confidence interval (95%CI). After multivariate analysis, social capital - in its structural component - was associated with functional disability. Older adults who were dissatisfied with the neighborhood had a higher risk of developing functional disability for IADL (HR = 2.36; 95%CI: 1.31-4.24), in relation to their counterparts. This study results suggest that functional disability is associated with aspects other than health, evidencing the need for the development of policies and interventions that support aspects related to the physical and social environment in which older adults live.

O objetivo do presente estudo foi investigar a associação entre capital social e a incapacidade funcional, numa perspectiva longitudinal, utilizando dados da coorte de idosos de Bambuí, Minas Gerais, Brasil. A linha de base do estudo foi composta por todos os idosos sobreviventes e livres de incapacidade no sétimo ano de seguimento (2004), acompanhados até 2011. A variável desfecho foi a incapacidade funcional para as ABVD (atividades básicas de vida diária) e AIVD (atividades instrumentais de vida diária), analisadas separadamente. A exposição de interesse foi o capital social, mensurado por meio de seus componentes cognitivo (coesão e suporte social) e estrutural (participação social e satisfação com a vizinhança). Variáveis sociodemográficas, de condições de saúde e de hábitos de vida foram utilizadas para efeitos de ajuste, e a ocorrência de óbito foi considerada evento competitivo. A hipótese de associação entre capital social e incapacidade funcional foi testada por meio do modelo de riscos competitivos, que fornece hazard ratios (HR) e intervalos de 95% de confiança (IC95%). Após a análise multivariada, o capital social, em seu componente estrutural, esteve associado à incapacidade funcional. Idosos insatisfeitos com a vizinhança apresentaram risco maior de desenvolver incapacidade funcional para AIVD (HR = 2,36; IC95%: 1,31-4,24), em relação às suas contrapartes. Os resultados desse estudo sugerem que a incapacidade funcional está associada a outros aspectos que não somente da saúde, evidenciando a necessidade de desenvolver políticas e intervenções que abarquem aspectos ligados ao ambiente físico e social em que o idoso está inserido.

El objetivo de este estudio fue investigar la asociación entre el capital social y la discapacidad funcional desde una perspectiva longitudinal, utilizando datos de la cohorte de ancianos de Bambuí, Minas Gerais, Brasil. La línea de base de este estudio estaba compuesta por todos los supervivientes de edad avanzada y sin discapacidad en el séptimo año de seguimiento (2004), seguidos hasta 2011. La variable de resultado fue la discapacidad funcional para las ABVD (actividades básicas de la vida diaria) y las AIVD (actividades instrumentales de la vida diaria), analizadas por separado. La exposición de interés fue el capital social, medido a través de sus componentes cognitivo (cohesión y apoyo social) y estructural (participación social y satisfacción con el barrio). Se utilizaron variables sociodemográficas, de condiciones de salud y de estilo de vida para los efectos de ajuste, y la ocurrencia de la muerte se consideró un evento competitivo. La hipótesis de asociación entre el capital social y la discapacidad funcional se probó mediante el modelo de riesgos competitivos, que proporciona tasas de riesgo (hazard ratios, HR) e intervalos del 95% de confianza (IC95%). Tras el análisis multivariante, el capital social en su componente estructural se asoció con la discapacidad funcional. Los ancianos insatisfechos con su vecindario tenían un mayor riesgo de desarrollar una discapacidad funcional para las AIVD (HR = 2,36; IC95%: 1,31-4,24) en comparación con sus homólogos. Los resultados sugieren que la discapacidad funcional está asociada a otros aspectos además de la salud, lo que pone de manifiesto la necesidad de desarrollar políticas e intervenciones que abarquen aspectos relacionados con el entorno físico y social en el que se insertan las personas mayores.

Diabetes, depressive symptoms, and mortality risk in old age: The role of inflammation.

BACKGROUND: Both diabetes and depression increase the mortality risk in the elderly. In this study, we evaluated mortality risk associated with the comorbidity between depression and diabetes. We also assessed the moderating role of inflammation in the mortality risk in this population. METHODS: We included a total of 1,183 community-dwelling older adults, divided into four groups: "neither diabetes nor depression"; "diabetes only"; "depression only," and "both diabetes and depression," and followed-up for a median of 13.5 years. We evaluated the inflammatory status by the high-sensitivity C-reactive protein (hs-CRP) levels. Date of death was computed by reviewing death certificates. We used Cox's proportional hazards models and additive interactions to evaluate the risk of mortality in the subject groups and the moderating effect of hs-CRP. RESULTS: Participants with both diabetes and depression had higher death risk (hazard ratio [HR]: 2.33; 95% confidence interval [CI]: 1.59-3.42) than those with each condition alone (HR diabetes: 2.08 95% CI: 1.56-2.76 HR depression: 1.26; 95% CI: 1.03-1.54). High level of hs-CRP, indicative of high inflammatory status, significantly moderated the risk of mortality in subjects with both diabetes and depression (Bonferroni-adjusted p = 0.0116). CONCLUSIONS: The coexistence of diabetes and depression symptoms is associated with the highest death risk in this population. This risk is moderated by inflammatory status.

Potentially inappropriate medications: predictor for mortality in a cohort of community-dwelling older adults.

PURPOSE: The objective of this study was to investigate whether the potentially inappropriate medication (PIM) use is a predictor for mortality in a community-based population of older adults. METHODS: A cohort study was performed between January 1, 1997, and December 31, 2011, based on data from a representative sample of the population aged 60 years or older living in Bambuí, Brazil. Univariate and multivariate analyses of the association between the variable of interest (use of PIM or pharmacological groups of PIM) and mortality were based on the extended Cox model for proportional hazards. The extended model was adopted to include the measurement of the exposure of interest throughout the follow-up period and not only at baseline. Adjustment variables included sociodemographic characteristics, health status, and use of health care services and medications. A level of significance of 5% was adopted for all analyses. RESULTS: The prevalence of PIM use was 56.0% (95%CI 53.4-58.6). After multiple adjustments, the risk of death among users of at least one PIM was 44% higher (HR = 1.44; 95%CI 1.21 to 1.71) than among those who did not use any PIM. Among the PIM groups analyzed, antipsychotics were the most strongly associated with mortality (HR = 2.33; 95%CI 1.72 to 3.17). CONCLUSIONS: The study revealed a high prevalence of PIM use among the community-based aged population. It also identified PIM use as a predictor for mortality in this group of individuals. This indicates the need for selection of safer drug therapy alternatives in this patient group.

Apolipoprotein E polymorphism and functional disability in Brazilian elders: the Bambuí Health and Aging Study.

Numerous studies have associated the apolipoprotein E (apoE) ε4 allele with worse health status, but few have assessed the existence of genotype-dependent variations in functional performance. Among participants in the Bambuí Health and Aging Study, Minas Gerais State, Brazil, 1,408 elderly underwent apoE genotyping. Functionality was assessed with a questionnaire, and individuals were classified as dependent in basic activities of daily living (BADLs), instrumental activities of daily living (IADLs), and mobility. The association between apoE genotype and functional status was assessed by logistic regression, taking confounding factors into account. Presence of ε4 allele was associated with lower odds of mobility deficit (OR = 0.65; 95%CI: 0.47-0.92) in the adjusted analysis. There were no significant differences in relation to presence of dependency in BADLs and IADLs. The reasons are not entirely understood, but they may involve the role of ε4 allele as a "thrifty gene" in a sample exposed to high risk of infectious and nutritional diseases in the past.

Absence of routine medical consultation among hypertensive and/or diabetic elders: an epidemiological study based on the Brazilian National Household Survey 2008.

OBJECTIVE: This exploratory study aimed to investigate the predisposing, enabling and health need characteristics associated with lack of medical visits in the last 12 months, among 23,620 elderly hypertensive and/or diabetic individuals. METHODS: In this research, we used the theoretical behavioral model of Andersen and Newman for use of health services. The data analyzed were produced by the health supplement of the Brazilian National Household Survey (PNAD) 2008, nationwide. To identify the associations, we used the Poisson regression model, which estimates the prevalence ratios and confidence intervals of 95%, considering the significance level of 5%. RESULTS: The results showed that 10.6% of the study population did not consult the doctor in the period considered, and the prevalence was higher among hypertensive subjects (10.5%) than among diabetic ones (7.1%). The lack of medical consultation was negatively associated with female sex and increasing age (predisposing characteristics), with health insurance coverage (enabling characteristic), worse self-rated health, chronic health conditions selected and the presence of hypertension associated with diabetes (health needs), while the fact of living in the Northeast, North and Midwest appeared positively associated with the event under investigation. CONCLUSION: These results corroborate those observed in national and international studies and show evidence of inequality and inequity in the use of medical consultation for this population, based on the findings related to health plan coverage and geographic region.

Social capital and under-utilization of medication for financial reasons among elderly women: evidence from two Brazilian health surveys.

This cross-sectional study assesses the prevalence and examines the role of social and demographic factors, health conditions, health system characteristics and contextual factors of under-utilization of medication for financial reasons among elderly women. Participants in the Greater Metropolitan Belo Horizonte Health Survey (GMBH) and the eleventh phase of the Bambuí Cohort Study of the Elderly were assessed. Among elderly women in the GMBH, the prevalence of under-utilization was 11.4%, and in Bambuí, the rate was 5.4%. Self-perception of health (OR, 3.46; 95%CI, 1.32_9.10); daily life limitations (OR, 2.75; 95% CI, 1.31-5.78) and perception of help (OR, 2.36; 95% CI, 1.07-5.25) had independent associations with under-utilization among GMBH residents. A poor perception of both cohesion in the neighborhood (OR, 2.38; 95% CI, 1.02-5.56) and the physical environment (OR, 2.58; 95% CI, 1.10-6.03) significantly increased the likelihood of under-utilization among Bambuí residents. These results provide important clues to identifying possible risk factors for under-utilization, highlighting the need to develop strategies targeting the amplification of the involvement between elderly women and their community to reduce the extent of under-utilization in later life.

Associated factors to self-rated health among hypertensive and/or diabetic elderly: results from Bambuí project.

OBJECTIVE: This study investigated the associated factors with negative self-rated health among hypertensive and/or diabetic elderly. METHODS: All the participants of Bambuí Project elderly cohort who suffered from hypertension and/or diabetes and who answered the questionnaire without the help of a close informant were selected for this (n = 942). Covariates encompassed sociodemographic characteristics, social support, health behaviors, health status and use of health services. RESULTS: Negative self-rated health showed positively associated with dissatisfaction with social relations (PR = 1.98, 95%CI 1.42 - 2.76), attendance at religious services less than once a month (PR = 1.96, 95%CI 1.44 - 2.68; be smokers (PR = 1.64, 95%CI 1.24 - 2.17), presence of arthritis (PR = 1.35, 95%CI 1.07 - 1.71), depressive symptoms (PR = 1.81, 95%CI 1.37 - 2.39) and insomnia (PR = 1.37, 95%CI 1.06 - 1.78), having consulted the doctor two or more times in the last twelve months (PR = 2.18; 95%CI 1.14 - 4.19 and PR = 3.96; 95%CI 2.10 - 7.48, respectively for "2 - 3" and "4+" visits), and have hypertension and diabetes (compared to the isolated presence of hypertension) CONCLUSIONS: Our results confirmed the multidimensional nature of self-rated health and were consistent with that observed in other national and international studies.

[Characteristics associated with the use of dental services by the adult Brazilian population]. / Características associadas ao uso de serviços odontológicos públicos pela população adulta brasileira.

The scope of this study was to investigate the factors related to the use of dental services by Brazilian adults. Data were collected from 13,356 adults (35 to 44 years of age), participating in a nationwide epidemiological survey of oral health (SB-BRASIL 2003 Project). Data analysis was based on Poisson regression, which produced estimates of Prevalence Ratios as a measure of association. Data analysis showed that the use of dental services by adults was associated with: female gender, low education and income, living in the Northeastern and Southern regions and in small cities, complaints of toothache or gum pain, need for partial/total prosthesis, a greater amount of permanent teeth requiring treatment, demand for service due to some dental problems and evaluation of dental care received on a regular basis. These results showed that the population attended by the public service was socio-economically less privileged and had greater need for treatment. This situation reflects an historical abandonment of the adult population by the dental healthcare system in Brazil and poses a major challenge to the Unified Health Service, in light of its intended role to reduce inequalities and provide universal access to comprehensive care.

[A population-based study on cost-related underuse of medicines by the elderly in Greater Metropolitan Belo Horizonte, Minas Gerais State, Brazil]. / Estudo de base populacional da subutilização de medicamentos por motivos financeiros entre idosos na Região Metropolitana de Belo Horizonte, Minas Gerais, Brasil.

The aim of this study was to estimate the prevalence of cost-related underuse of medicines and associated factors in a representative sample of 1,134 elderly individuals in Greater Metropolitan Belo Horizonte, Minas Gerais State, Brazil. Prevalence of cost-related underuse was 12.9%. After adjustments in the multivariate model, cost-related underuse was higher in individuals with income less than twice the minimum wage (PR = 0.57; 95%CI: 0.34-0.97), without health plan coverage (PR = 0.68; CI95%: 0.46-0.99), with low frequencies of physician-patient dialogue concerning health/treatment (rarely/never, PR = 1.79; 95%CI: 1.10-2.90), with fair to poor self-rated health (PR = 1.66; 95%CI: 0.95-2.90 and PR = 2.49; 95%CI: 1.38-4.48, respectively), and with multiple comorbidities (one, PR = 2.51; 95%CI: 0.99-6.35; two, PR = 3.51; 95%CI: 1.40-8.72 and three or more, PR = 4.52; 95%CI: 1.79-11.41). Our results suggest adherence problems within this population due to a communication gap between seniors and physicians on treatment-related aspects and to the lack of health plan coverage. Especially worrisome is the high risk of cost-related underuse among elderly with poor health.
