Effective primary care attenuates the association between frailty and hospital admission in old age: the ELSI-Brazil.

BACKGROUND: Frailty is a multidimensional syndrome leading to a higher hospitalization. However, few studies explicitly analyze whether measures of effective primary care modify the relationship between frailty and hospital admission. METHODS: This cross-sectional study included data from the second wave of the Brazilian Longitudinal Study of Aging (ELSI-Brazil), a representative community-based study with older adults aged 50 years and over, conducted in 2019-2021. Self-reported hospital admission in the past 12 months was the outcome. Frailty included the 5 phenotypic criteria: weight loss, exhaustion, low physical activity, weakness, and slowness. The effective primary care index included 12 attributes indicators, continuously. Statistical analyzes comprised logistic regression. RESULTS: Among the 7,436 study participants, frailty (odds ratio [OR] 2.17; 95% confidence intervals [95% CI] 1.31-3.62) and effective primary care index (OR 1.10; 95% CI 1.03-1.16) were positively associated with higher hospitalization. Interaction revealed that while effective primary care was positively associated with hospitalization, this association was different among frail older adults (OR 0.80; 95% CI 0.65-0.99). After stratification by frailty status, positive association with hospitalization remained only among prefrail and nonfrail individuals. The predicted probability of hospitalization tended to decrease along with higher primary care index values among frail older adults and became similar to prefrail/nonfrail at the highest end of the scale. CONCLUSIONS: Effective primary care decreases the likelihood of hospital admission among frail older adults. Interventions for delaying frailty should be initiated in primary care along with policies to strengthen primary care's organizational and provider/team-level attributes.

However, few studies explicitly analyze whether measures of effective primary care modify the relationship between frailty and hospital admission. Using data from the Brazilian Longitudinal Study of Aging (ELSI-Brazil), a representative community-based study with older adults aged 50 years and over, we evaluated self-reported hospital admission in the past 12 months, frailty according to 5 phenotypic criteria, and an effective primary care index with 12 attributes indicators. According to data of 7,436 study participants, we revealed that while effective primary care index was positively associated with hospital admission, this association was different among frail older adults. After stratification by frailty status, positive association with hospitalization remained only among prefrail and nonfrail individuals. Therefore, effective primary care decreases the likelihood of hospital admission among frail older adults.

Walking speed and home adaptations are associated with independence after stroke: a population-based prevalence study.

This study aimed at estimating the prevalence of stroke in older adults in Brazil, and at identifying the sociodemographic, health-related, health service-related, and environmental factors associated with independence in daily activities. Across-sectional, population-based study (Brazilian Longitudinal Study of Aging 2015-2016) was conducted. 536 individuals (≥ 50 years), from 9,412 participants, have had stroke and were included. Prevalence of stroke was 5.3% among individuals aged 50 years and over, increasing up to 8.0% among individuals aged 75 years and over, showing a dissimilar pattern between sex. Independence was associated with walking speed (Prevalence Ratio (PR) 2.72, 95%CI: 1.96 to 3.77), physical activity (PR 1.24; 95%CI: 1.04 to 1.47) and use of walking devices (PR 0.63; 95%CI: 0.41 to 0.96). A significant interaction was found between walking speed plus home adaptations and performance of daily living activities (PR 3.42; 95%CI: 1.04 to 11.29). The probability of independence was 40% among slow walkers (< 0.4 m/s), increasing up to 70% among fast walkers (> 0.8 m/s), and to 90% among those who also have home adaptations. Faster walking speed combined with home adaptations was the main factor associated with long-term independence after stroke.

Resumo Objetivou-se estimar a prevalência do acidente vascular cerebral (AVC) em brasileiros mais velhos, bem como identificar fatores sociodemográficos, de saúde, de serviços de saúde e ambientais associados à independência em atividades de vida diária. Trata-se de um estudo transversal de base populacional (Estudo Longitudinal da Saúde de Idosos Brasileiros 2015-2016). Dos 9.412 participantes, 536 indivíduos (≥ 50 anos) tiveram AVC e foram incluídos. A prevalência do AVC foi de 5,3% em indivíduos com 50 anos e mais, aumentando para 8% entre indivíduos com 75 anos e mais, com padrão dissimilar entre sexo. A independência foi associada à velocidade da marcha (razão de prevalência [RP] 2,72, IC95%: 1,96-3,77), atividade física (PR 1,24; IC95%: 1,04-1,47) e uso de dispositivos auxiliares de marcha (RP 0,63; IC95%: 0,41-0,96). Encontrou-se interação significativa para velocidade da marcha, adaptações no domicílio e a independência (RP 3,42; IC95%: 1.04-11.29). A probabilidade de independência foi de 40% nas velocidades mais baixas (< 0,4 m/s), e nas velocidades mais elevadas (> 0,8 m/s) foi de 70%, aumentando para 90% quando há adaptações no domicílio. A velocidade rápida da marcha e a adaptação no domicílio foram os principais fatores associados à independência a longo prazo após o AVC.

Combined Physical Activity and Sitting Time Association on Older Adults' Body Mass Index: Cross-Sectional Findings From the Brazilian Longitudinal Study of Aging.

This study examined isolated and combined associations of physical activity (PA) and sitting time (ST) with body mass index (BMI) among older Brazilian adults. We have analyzed baseline data of 8,177 participants aged 50 years and older from the Brazilian Longitudinal Study of Aging. Respondents were categorized into sufficient PA/low ST, sufficient PA/high ST, insufficient PA/low ST, or insufficient PA/high ST using the Short Version of International Physical Activity Questionnaire. Multinomial logistic regression analysis examined the associations of being underweight (BMI, <18 kg/m2), overweight (BMI, 25-29.9 kg/m2), and obese (BMI, ≥30 kg/m2) with PA and ST categories. High ST (≥165 min/day) was associated with overweight (odds ratio, 1.26; 95% confidence interval [1.11, 1.44]) and obesity (odds ratio, 1.43; 95% confidence interval [1.21, 1.70]). However, no association was observed between PA and BMI. Participants in the insufficient and sufficient PA/high ST categories were more likely to be obese after adjusting for sociodemographic and health condition. Our findings call for public health initiatives that consider reducing ST in older adults.

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

BACKGROUND: Chronic pain is known to increase health care use in high-income countries, but in Brazil, little is known. OBJECTIVE: To investigate the association between chronic pain and health care use among Brazilian older adults and explore the relationship between pain severity and health care use. METHODS: This cross-sectional study was derived from the population-based study Frailty in Brazilian Older People-FIBRA. Chronic pain, pain intensity and pain-related disability were assessed through additional telephone interviews. Health care use was measured by the number of doctor visits, hospitalization events and high health care use (highest quartile of the distribution for number of doctor visits) in the last 12 months. Associations were tested in regression analyses adjusted for predisposing, enabling and illness-level components from the Andersen Model. RESULTS: The 383 participants were predominantly female (71.0%), mean age was 75.6 (6.1 SD). The prevalence of chronic pain was 30.0%. Chronic pain was associated with number of doctor visits [unstandardized B coefficient 1.48; 95% confidence interval (CI) = 0.35-2.62] and high health care use [odds ratios (OR) = 2.27; 95% CI = 1.39-3.72]. Pain intensity was associated with high health care use in univariate (OR = 1.13; 95% CI = 1.06-1.20) but not multivariate analysis (OR = 1.12; 95% CI = 0.94-1.33). Pain-related disability was not associated with any outcome. CONCLUSION: Chronic pain increased health care use among Brazilian older adults. Improving the quality of primary care management of individuals at greater risk of chronic pain should be a cornerstone of health policies directed towards reducing the personal and societal burden of ageing.

Influence of sarcopenia and functionality indicators on the frailty profile of community-dwelling elderly subjects: a cross-sectional study.

BACKGROUND: Frailty and sarcopenia are frequent conditions in the elderly and are related to inactivity and functionality. However, little is known about the influence of the sarcopenia indicators on the frailty profile or their functional implications. OBJECTIVE: To evaluate whether the indirect indicators of sarcopenia and functionality influence the frailty profile in elderly subjects. METHOD: This was a cross-sectional study with 53 elderly subjects recruited by an active search in a secondary health care service. The indirect indicators of sarcopenia were body mass index (BMI), gait speed, Mini-Nutritional Assessment (MNA), Human Activity Profile (HAP), and handgrip strength. Frailty was characterized according to Fried's Frailty Phenotype. Functional capacity was assessed according to the Short Physical Performance Battery (SPPB). Physical activity level was assessed by HAP. Data were analyzed by analysis of variance (ANOVA) and multiple regression. RESULTS: Overall, 75.5% of the subjects were women, with a mean age of 76.72 (±5.89) years; 15.1% were frail and 54.7% pre-frail; and the level of physical activity was the most prevalent indicator of sarcopenia. Significant differences (p<0.05) were observed in both the physical activity level and gait speed between the non-frail and pre-frail groups and between the non-frail and frail groups. In addition, some sarcopenia indicators were associated with functional capacity and geriatric depression score. CONCLUSION: The level of physical activity and gait speed appeared to be the most relevant factors in the development of frailty in the study sample, which may have functional implications.

Inspiratory muscular training in chronic stroke survivors: a randomized controlled trial.

OBJECTIVE: To assess the effectiveness of inspiratory muscular training (IMT) on measures of strength, resistance, functional performance, and quality of life (QOL) for chronic stroke survivors. DESIGN: Double-blinded randomized controlled trial. SETTING: Research laboratory. PARTICIPANTS: Subjects (N=21) with stroke (11 men, 10 women; maximal inspiratory pressure [MIP] <90% of predicted values) were randomly assigned to the experimental (n=11) and control groups (n=10); 18 participants completed all testing and training. INTERVENTIONS: Interventions were based on home-based training, with resistance adjusted biweekly to 30% of MIP for the experimental group. The control group underwent the same protocol without the threshold resistance valve. Both groups received home training 30 minutes a day 5 times a week for 8 weeks. MAIN OUTCOME MEASURES: MIP, inspiratory muscular endurance (IME), functional performance, and QOL. RESULTS: There were significant between-group differences for the MIP and IME measures. Significant changes were observed for only the experimental group for MIP (67.8±14.6 at baseline to 102.2±26.0cmH(2)O at posttraining) and IME (31.8±19.3 to 49.2±21.1cmH(2)O). No statistically significant differences were observed for measures of functional performance and QOL. CONCLUSIONS: Significant short-term effects of the IMT program for inspiratory strength and endurance were observed in chronic stroke survivors. These findings gave some indications that IMT may benefit people with stroke, and it is feasible to be included in rehabilitation interventions with this population.
