RESUMO

ABSTRACT Objective: To estimate the prevalence of multimorbidity in elderly people and its association with sociodemographic characteristics, lifestyle, and anthropometry. Methods: This was a cross-sectional study using data from the National Health Survey, 2019. A total of 22,728 elderly individuals from all 27 Brazilian states were randomly selected. Poisson regression models with robust variance were employed, and a significance level of 5% was adopted. Results: The prevalence of multimorbidity was 51.6% (95% CI: 50.4-52.7), with the highest estimates observed in the South and Southeast. Multimorbidity was associated with being female (aPR = 1.33; 95% CI: 1.27-1.39), being 80 years old or older (aPR = 1.12; 95% CI: 1.05-1.19), having low education (aPR = 1.16; 95% CI: 1.07-1.25), past cigarette use (aPR = 1.16; 95% CI: 1.11-1.21), insufficient physical activity (aPR = 1.13; 95% CI: 1.06-1.21), and screen use for 3 hours or more per day (aPR = 1.13; 95% CI: 1.08-1.18). Conclusion: Multimorbidity affects more than half of the elderly population in Brazil and is associated with social, demographic, and behavioral factors.

RESUMO

Introduction: Multimorbidity, defined as the coexistence of two or more chronic diseases in the same individual, represents a significant health challenge. However, there is limited evidence on its prevalence and associated factors in developing countries, such as Brazil, especially stratified by sex. Thus, this study aims to estimate the prevalence and analyze the factors associated with multimorbidity in Brazilian adults according to sex. Methods: Cross-sectional population-based household survey carried out with Brazilian adults aged 18 years or older. The sampling strategy consisted of a three-stage conglomerate plan. The three stages were performed through simple random sampling. Data were collected through individual interviews. Multimorbidity was classified based on a list of 14 self-reported chronic diseases/conditions. Poisson regression analysis was performed to estimate the magnitude of the association between sociodemographic and lifestyle factors with the prevalence of multimorbidity stratified by sex. Results: A total of 88,531 individuals were included. In absolute terms, the prevalence of multimorbidity was 29.4%. The frequency in men and women was 22.7 and 35.4%, respectively. Overall, multimorbidity was more prevalent among women, the older people, residents of the South and Southeast regions, urban area residents, former smokers, current smokers, physically inactive, overweight, and obese adults. Individuals with complete high school/incomplete higher education had a lower prevalence of multimorbidity than those with higher educational level. The associations between education and multimorbidity differed between sexes. In men, multimorbidity was inversely associated with the strata of complete middle school/incomplete high school and complete high school/incomplete higher education, while in women, the association between these variables was not observed. Physical inactivity was positively associated with a higher prevalence of multimorbidity only in men. An inverse association was verified between the recommended fruit and vegetable consumption and multimorbidity for the total sample and both sexes. Conclusion: One in four adults had multimorbidity. Prevalence increased with increasing age, among women, and was associated with some lifestyles. Multimorbidity was significantly associated with educational level and physical inactivity only in men. The results suggest the need to adopt integrated strategies to reduce the magnitude of multimorbidity, specific by gender, including actions for health promotion, disease prevention, health surveillance and comprehensive health care in Brazil.

RESUMO

Objective To assess if the duration and quality of sleep vary due to the presence of multimorbidity. Materials and Methods We performed a secondary analysis using data from a population-based study involving adult subjects aged between 30 and 69 years residing in a semi-urban area of Tumbes, Peru. The duration (normal, short or prolonged) and quality (good or poor) of sleep were our outcome variables, whereas the exposure was multimorbidity (two or more chronic conditions). Crude and adjusted Poisson regression models were built to assess the association of interest, and prevalence ratios (PRs) and 95% confidence intervals (95%CIs) were reported. Results We analyzed data from 1,607 subjects with a mean age of 48.2 (standard deviation [SD]: ± 10.6) years, 809 (50.3%) of whom were women. Multimorbidity was present in 634 (39.5%; 95%CI: 37.1-41.9%) subjects, and 193 (12.1%; 95%CI: 10.5-13.7%) were short sleepers, 131 (8.2%; 95%CI: 6.9-9.6%) were long sleepers, and 312 (19.5%; 95%CI: 17.5-21.5%) had poor sleep quality. In the multivariable model, multimorbidity was associated with prolonged sleep duration (PR = 1.45; 95%CI: 1.03-2.04) and poor sleep quality (PR = 2.04; 95%CI: 1.65-2.52). Conclusions Multimorbidity was associated with prolonged, but not short, sleep duration, as well as with poor sleep quality. Our results suggest the need of assessing sleep patterns among adults with multimorbidity.

RESUMO

Objective: To identify multimorbidity patterns in women in southern Brazil, and its relationship with sociodemographic, lifestyle characteristics, and nutritional status, as well as to explore the main independent risk factor for the identified patterns. Subjects and methods: This is a cross-sectional, population-based study with 1,128 women (20-69 years), southern Brazil. Chronic conditions were identified using the therapeutic and chemical anatomical classification of continuous use of medications. Multimorbidity was assessed as ≥2 or ≥3 chronic conditions to identify dyads and triads. Poisson regression was used to explore risk factors in the different adjustment models. As independent variables evaluated, in addition to sociodemographic characteristics, lifestyle variables were included: consumption of fruits and vegetables, physical activity, alcohol consumption, smoking and nutritional status. Results: Eleven dyads (frequencies between 2.0% and 6.4%) and three triads (frequencies between 1.9% and 2.1%) of morbidities were identified in the study. Aging was related to a higher prevalence of all patterns, and obesity was a risk factor for multimorbidity patterns that contained conditions related to the cardiovascular and metabolic system and mental health. After adjustment, obesity increased the probability of "hypertension + common mental disorders (CMD)" (PR 3.63; 95% CI 1.94-6.78) and "dyslipidemia + CMD" (PR 3.69; 95% CI 1.08-12.65) by more than three times. Conclusion: This study identified common and important diseases in the patterns, associated with a common risk factor, obesity, that must be addressed by public health policies to prevent multimorbidity.

RESUMO

Objective: To estimate the prevalence of simultaneity of obesity, hypertension and/or diabetes and the association with sociodemographic and lifestyle-related behavior variables. Methods: This is a cross-sectional study with data from the 2013 National Health Survey. The presence of two/three diseases (obesity, hypertension, and diabetes) was considered multimorbidity of noncommunicable diseases (NCDs). Proportional odds logistic regression model, stratified by sex, was used to assess the sociodemographic and lifestyle factors associated with multimorbidity of NCDs, considering the sample complexity and sample weights. Results: The prevalence of multimorbidity of NCDs was 9.6%. The odds of multimorbidity are higher with increasing age, among blacks, but lower in the north region when compared with other regions of the country for both sexes. The odds of multimorbidity of NDCs increased among women who had lower levels of education and spent more time TV watching, and among men who lived with a partner and did not practice the recommended leisure-time physical activity. Conclusion: Sociodemographic factors and lifestyle-related behaviors were associated with the presence of obesity, hypertension, and/or diabetes.

Objetivo: Estimar la prevalencia de simultaneidad de obesidad, hipertensión y/o diabetes y la asociación con variables sociodemográficas y relacionadas con el estilo de vida. Métodos: Los datos fueron obtenido en la Encuesta Nacional de Salud Brasileña, una encuesta a nivel nacional, realizada en los hogares brasileños y llevada a cabo en 2013. La presencia de dos /tres enfermedades (obesidad, hipertensión y diabetes) se consideró multimorbilidad de las enfermedades no transmisibles (ENT). El modelo de regresión logística de probabilidades proporcionales, estratificado por sexo, se utilizó para evaluar los factores sociodemográficos y de estilo de vida asociados con la multimorbilidad de las ENT, considerando la complejidad de la muestra y los pesos de la muestra. Resultados: La prevalencia de multimorbilidad de las ENT fue del 9,6%. Las probabilidades de multimorbilidad son más altas con el aumento de la edad, entre los negros, pero más bajas en la región norte en comparación con otras regiones del país para los dos sexos. Las probabilidades de multimorbilidad de las ENT aumentaron entre las mujeres que tenían niveles más bajos de educación y pasaban más tiempo viendo la televisión, y entre los hombres que vivían con una pareja y no practicaban la actividad física recomendada para el tiempo libre. Conclusión: Los factores sociodemográficos y los comportamientos relacionados con el estilo de vida se asociaron con la presencia de obesidad, hipertensión y/o diabetes.

RESUMO

Resumo Objetivo Descrever os casos clinicamente complexos de crianças com necessidades de saúde especiais em hospitalização contínua e analisar a natureza das demandas de cuidados clinicamente complexos durante a hospitalização. Métodos Estudo de casos múltiplos de três crianças clinicamente complexas hospitalizadas. A coleta de dados ocorreu, entre janeiro e março de 2020, em prontuário, na observação de cuidados e interação espontânea registrada em diário de campo e entrevista. Participaram sete pessoas, sendo dois familiares, três técnicos de enfermagem e duas enfermeiras. Aplicou-se a análise temática, orientando-se pela tipologia de demandas de cuidados de crianças com necessidades de saúde especiais e classificação de Collière. Resultados Os casos de meninas e menino, com três, dez e 11 anos de idade, e tempo de internação de 4 meses a 6 anos, geraram linhas de convergências com as demandas de cuidados de crianças com necessidades de saúde especiais, proporcionando sobrevivência, bem-estar e conforto. Desses casos extraíram-se demandas contínuas e complexas de cuidados de estimulação, apaziguamento, confortação e parecer convergentes com o de desenvolvimento e habituais modificados (banho, arrumar-se, alimentação e mobilidade); os cuidados de compensação, no manejo de tecnologias corporais e a administração de medicamentos de uso contínuo, convergiram para demandas de cuidados tecnológicos e medicamentosos Conclusão A necessidade de sobrevivência, determinada pela natureza clinicamente complexa da criança, direciona a prioridade dos cuidados no uso contínuo de múltiplos medicamentos e manejo de tecnologias, na segurança do ambiente hospitalar. Embora essenciais, precisa-se contemplar as outras demandas de cuidados de desenvolvimento e social integrando-as às clinicamente complexas.

Resumen Objetivo Describir los casos clínicamente complejos de infantes con necesidades de salud especiales en hospitalización continua y analizar la naturaleza de las demandas de cuidados clínicamente complejos durante la hospitalización. Métodos Estudio de casos múltiples de tres infantes hospitalizados clínicamente complejos. La recopilación de datos se realizó de enero a marzo de 2020, en la historia clínica, en la observación de cuidados e interacción espontánea registrada en un diario de campo y en entrevista. Participaron siete personas, de las cuales dos eran familiares, tres técnicos de enfermería y dos enfermeras. Se aplicó el análisis temático, orientándose por la tipología de demandas de cuidados de infantes con necesidades de salud especiales y clasificación de Collière. Resultados Los casos de las niñas y el niño, de 3, 10 y 11 años, entre 4 meses y 6 años de tiempo de internación, generaron líneas convergentes con las demandas de cuidados de infantes con necesidades de salud especiales, donde se proporciona supervivencia, bienestar y consuelo. De estos casos se observaron demandas continuas y complejas de cuidados de estimulación, apaciguamiento, consuelo y opinión convergentes con los del desarrollo y los habituales modificados (baño, arreglarse, alimentación y movilidad); los cuidados de compensación, con el manejo de tecnologías corporales y la administración de medicamentos de uso continuo, convergieron en las demandas de cuidados tecnológicos y medicamentosos. Conclusión La necesidad de supervivencia, determinada por la naturaleza clínicamente compleja del infante, direcciona la prioridad de los cuidados en el uso continuo de múltiples medicamentos y en el manejo de tecnologías para la seguridad del ambiente hospitalario. Aunque sean esenciales, es necesario contemplar otras demandas de cuidados de desarrollo y sociales e integrarlas a las clínicamente complejas.

Abstract Objective To describe the medically complex cases of children with special healthcare needs in continuous hospitalization and to analyze the nature of medically complex care demands during hospitalization. Methods This is a multiple case study of three hospitalized medically complex children. Data collection occurred between January and March 2020 in the medical records in the observation of care and spontaneous interaction documented in a fieldwork note and interview. Seven people participated, two family members, three nursing technicians, and two nurses. Thematic analysis was applied, guided by the typologies of Collière's care and the demands of children with special healthcare needs. Results The cases included girls and a boy aged three, ten, and 11 years, and hospitalization time from 4 months to 6 years. They all generated lines of convergence with the care demands of children with special healthcare needs, providing survival, well-being, and comfort. These cases extracted continuous and complex care demands of stimulation, pacification, and comfort; and seemed convergent with developmental and modified daily life activities (bath, grooming, feed, and mobility) care. Compensating care in managing bodily technologies and administering continuous-use medication converged with demands for technological and medication care. Conclusion The need for survival, determined by children's medically complex nature, directs the priority of care to the continuous use of multiple medications, the management of technologies, and the safety of hospital environments. Although essential, it is necessary to consider the other developmental and social care demands, integrating them with the medically complex ones.

RESUMO

ABSTRACT: Objective: This study aimed to identify the prevalence of multimorbidity and its associated factors in women in southern Brazil. Methods: We conducted a cross-sectional, population-based study with a sample of 1,128 women (age 20-69 years), living in São Leopoldo, southern Brazil. Multimorbidity was defined as two or more chronic conditions measured using the therapeutic and chemical anatomical classification of continuous use medications prescribed by a physician. Poisson regression model with robust variance was used to assess the association between sociodemographic and lifestyle variables and multimorbidity. Results: The prevalence of multimorbidity was 21.7% (95%CI 19.3-24.2), and 26 chronic conditions were identified. A direct linear association was observed with age and income and an inverse association with education. Being unemployed was a risk factor for multimorbidity (PR 1.95; 95%CI 1.51-2.52). Alcohol consumption (moderate or excessive) had a protective effect. Overweight and obese women were 53% (PR 1.53; 95%CI 1.09-2.15) and 76% (PR 1.76; 95%CI 1.27-2.45) more likely to have multimorbidity than eutrophic women. Conclusion: Over 20% of the adult women had multimorbidity, and its occurrence was strongly associated with socioeconomic characteristics, such as fewer years of schooling, higher income, and not having an occupation. The results regarding alcohol consumption are still insufficient to propose a public policy for the prevention of multimorbidity. Excess weight was an independent risk factor and should be addressed in public health policies for the prevention and management of multimorbidity.

RESUMO

A multimorbidade tem sido cada vez mais comum em todo o mundo. O acesso a serviços de saúde eficazes e equitativos que atendam às necessidades das doenças crônicas não-transmissíveis (DCNT) ainda é limitado em muitos países. Nesse sentido, o presente estudo teve por objetivo identificar a relação entre a multimorbidade e a utilização de diferentes serviços de saúde e avaliar a associação entre fatores contextuais e individuais e o uso de serviços de saúde em indivíduos com multimorbidade no Brasil de 1998 a 2013. Trata-se de um estudo em painéis utilizando dados do suplemento de saúde da Pesquisa Nacional de Amostras por Domicílios de 1998, 2003 e 2008 e dados da Pesquisa Nacional de Saúde realizada em 2013. A população de estudo foi composta por adultos com idade maior ou igual a 18 anos e classificados como tendo multimorbidade (presença de dois ou mais problemas crônicos em um mesmo indivíduo). Foram considerados três desfechos de utilização de serviços de saúde: busca por serviços de saúde nos últimos quinze dias, consulta médica nos últimos doze meses e hospitalizações nos últimos doze meses. Modelos de regressão de Poisson estratificados por sexo foram utilizados para estimar as razões de prevalência brutas e ajustadas e seus respectivos intervalos de confiança de 95% para cada desfecho de uso de serviços de saúde e multimorbidade, por ano. Modelos de regressão de Poisson multinível em dois níveis foram utilizados para estimar as razões de prevalência ajustadas por variáveis independentes individuais e contextuais e seus respectivos intervalos de confiança a 95%, para os três desfechos, por ano de painel. Houve aumento da prevalência de procura por serviços de saúde e consultas médicas nos últimos 12 meses entre 1998 e 2013, independentemente da classificação de multimorbidade. A prevalência de hospitalizações diminuiu ao longo do período do estudo e foi duas vezes maior em indivíduos com multimorbidade. Ter multimorbidade aumentou a utilização de serviços de saúde para os três desfechos em estudo, sendo mais expressivo entre os homens. Fatores individuais relacionados ao uso de serviços de saúde se modificaram segundo tipo de serviço de saúde investigado. Características contextuais de vulnerabilidade social, organização dos serviços de saúde e índices de saúde mostraram influência na busca por serviços de saúde e nas hospitalizações, não apresentando associação com consultas médicas. Este estudo constatou que indivíduos com multimorbidade apresentam níveis mais elevados de utilização de serviços de saúde. Além disso, revelou que o uso de serviços de saúde está associado de forma variável com os fatores predisponentes, capacitantes e de necessidade em pessoas com multimorbidade. Esses resultados apontam para a necessidade de integrar todos os fatores individuais e contextuais no planejamento do acesso à saúde e, assim, reduzir as desigualdades no acesso aos serviços de saúde nessa população.

Background: Multimorbidity has been increasingly common throughout the world. Access to effective and equitable health services that address the needs of chronic non-communicable diseases (NCDs) is still limited in many countries. In this sense, the present study aimed to identify the relationship between multimorbidity and the use of different health services and to assess the association between contextual and individual factors and the use of health services in individuals with multimorbidity in Brazil from 1998 to 2013. Methods: This is a panel study using data from the health supplement of 1998, 2003, and 2008 National Survey of Samples by Households and data from the National Health Survey conducted in 2013. The study population consisted of adults of age 18 years of age or older and classified as having multimorbidity (presence of two or more chronic problems in the same individual). Three health service utilization outcomes were considered: search for health services in the last fifteen days, medical consultation in the last twelve months, and hospitalisations in the last twelve months. Poisson regression models stratified by sex were used to estimate the crude and adjusted prevalence ratios and their respective 95% confidence intervals for each health service use and multimorbidity outcome per year. Two-level multilevel Poisson regression models were used to estimate the prevalence ratios adjusted for individual and contextual independent variables and their respective 95% confidence intervals, for the three outcomes, by panel year. Results: There was an increase in the prevalence of demand for health services and medical consultations in the last 12 months between 1998 and 2013, regardless of the multimorbidity classification. The prevalence of hospitalisations decreased over the study period and was twice as high in individuals with multimorbidity. Having multimorbidity increased the use of health services for the three outcomes under study, being more expressive among men. Individual factors related to the use of health services changed according to the type of health service investigated. Contextual characteristics of social vulnerability, organization of health services, and health indices influenced the search for health services and hospitalisations, with no association with medical appointments. Conclusion: This study found that individuals with multimorbidity have higher levels of use of health services. Furthermore, it revealed that the use of health services is variably associated with predisposing, enabling, and need factors in people with multimorbidity. These results point to the need to integrate all individual and contextual factors in planning access to health and, thus, reduce inequalities in access to health services in this population.

RESUMO

OBJECTIVES: This study assessed the moderating role of education on the relationship between multimorbidity and mortality among older adults in Brazil. STUDY DESIGN: This was a cohort study. METHODS: This study used data from 1768 participants of the Health, Well-Being and Ageing Cohort Study (SABE) who were assessed between 2006 and 2015. The Cox Proportional Risks Model was used to evaluate the association between multimorbidity (two or more chronic diseases) and mortality. An interaction term between education and multimorbidity was included to test the moderating role of education in this association. RESULTS: The average follow-up time was 4.5 years, with a total of 589 deaths in the period. Multimorbidity increased the risk of mortality (hazard ratio [HR] 1.55, 95% confidence interval [CI] 1.27-1.91), and this association was not moderated by education (HR 1.06, 95% CI 1.00-1.13; P value = 0.07). CONCLUSIONS: The impact of education and multimorbidity on mortality emphasises the need for an integrated approach directed towards the social determinants of health to prevent multimorbidity and its burden among older adults.
