RESUMO

This systematic review and meta-analysis (PROSPERO CRD42023428105) investigated the effect of dancing on depression and anxiety symptoms in older adults. Conducted up to October 2023, the search across seven databases and gray literature yielded 5020 records. Only randomized trials that analyzed dance interventions for depression and/or anxiety in older adults were included. Nineteen randomized trials, involving 508 participants in dance classes lasting 5 weeks to 18 months, were included and 16 were subjected to meta-analysis. Risk of bias was assessed using the Cochrane tool. The meta-analysis showed a statistically significant reduction in depression among older adults participating in dance interventions (p < 0.01). A decrease in depressive symptoms was significant compared to that in those involved in no other intervention (p = 0.02) but not compared to that achieved with other interventions in control groups (p = 0.96). Subgroup analysis showed no significant differences in depression scores for those with mild cognitive impairment (p = 0.47). These conclusions are associated with moderate bias and very low certainty. Due to heterogeneity and the small number of studies, conclusions for anxiety outcomes could not be drawn. These results underscore the potential clinical relevance of integrating dance into mental health interventions for older adults, thereby highlighting a promising avenue for enhancing the mental well-being of this demographic.

RESUMO

INTRODUCTION: Worldwide, the prevalence of degenerative diseases such as dementia and mild cognitive impairment (MCI) is increasing with population ageing and increasing life expectancy. Both conditions share modifiable risk factors. Physical inactivity is one of these modifiable risk factors, and research points to the protective effect of physical activity on the incidence of dementia and MCI. However, this association tends to change according to type, intensity, frequency, duration and volume of physical activity. Furthermore, it remains unclear which of these characteristics offers the greatest protective effect. Therefore, this study aims to evaluate the impacts of different types, intensities, frequencies, duration and volume of physical activity on dementia and cognitive decline in older adults. METHODS AND ANALYSIS: The search will be carried out from October 2023, using the following databases: PubMed, Embase, Scopus, CINAHL and Web of Science. Cohort studies with a follow-up time of 1 year or longer that have investigated the incidence of dementia and/or MCI in older adults exposed to physical activity will be included. There will be no limitations on the date of publication of the studies. Studies published in English, Spanish or Portuguese will be analysed. Two researchers will independently screen the articles and extract the data. Any discrepancies will be resolved by a third reviewer. Association measures will be quantified, including OR, HR, relative risk and incidence ratio, with a 95% CI. If the data allow, a meta-analysis will be performed. To assess the methodological quality of the selected studies, the Grading of Recommendations, Assessment, Development and Evaluations instrument, and the Downs and Black instrument to assess the risk of bias, will be used. ETHICS AND DISSEMINATION: Ethical approval is not required. The results will be submitted for publication in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42023400411.

RESUMO

To investigate the prevalence of multimorbidity and complex multimorbidity and their association with sociodemographic and health variables in individuals with severe obesity. This is a baseline data analysis of 150 individuals with severe obesity (body mass index ≥ 35.0 kg/m2) aged 18-65 years. The outcomes were multimorbidity and complex multimorbidity. Sociodemographic, lifestyle, anthropometric and self-perceived health data were collected. Poisson multiple regression was conducted to identify multimorbidity risk factors. The frequency of two or more morbidities was 90.7%, three or more morbidities was 76.7%, and complex multimorbidity was 72.0%. Living with four or more household residents was associated with ≥ 3 morbidities and complex multimorbidity. Fair and very poor self-perceived health was associated with ≥ 2 morbidities, ≥ 3 morbidities and complex multimorbidity. A higher BMI range (45.0-65.0 kg/m2) was associated with ≥ 2 morbidities and ≥ 3 morbidities. Anxiety (82.7%), varicose veins of lower limbs (58.7%), hypertension (56.0%) were the most frequent morbidities, as well as the pairs and triads including them. The prevalence of multimorbidity and complex multimorbidity in individuals with severe obesity was higher and the risk for multimorbidity and complex multimorbidity increased in individuals living in households of four or more residents, with fair or poor/very poor self-perceived health and with a higher BMI.

RESUMO

BACKGROUND: Although the association between multimorbidity (MM) and hospitalisation is known, the different effects of MM patterns by age and sex in this outcome needs to be elucidated. Our study aimed to analyse the association of hospitalisations' variables (occurrence, readmission, length of stay) and patterns of multimorbidity (MM) according to sex and age. METHODS: Data from 8.807 participants aged ≥ 50 years sourced from the baseline of the Brazilian Longitudinal Study of Ageing (ELSI-Brazil) were analysed. Multimorbidity was defined as ≥ 2 (MM2) and ≥ 3 (MM3) chronic conditions. Poisson regression was used to verify the association between the independent variables and hospitalisation according to sex and age group. Multiple linear regression models were constructed for the outcomes of readmission and length of stay. Ising models were used to estimate the networks of diseases and MM patterns. RESULTS: Regarding the risk of hospitalisation among those with MM2, we observed a positive association with male sex, age ≥ 75 years and women aged ≥ 75 years. For MM3, there was a positive association with hospitalisation among males. For the outcomes hospital readmission and length of stay, we observed a positive association with male sex and women aged ≥ 75 years. Network analysis identified two groups that are more strongly associated with occurrence of hospitalisation: the cardiovascular-cancer-glaucoma-cataract group stratified by sex and the neurodegenerative diseases-renal failure-haemorrhagic stroke group stratified by age group. CONCLUSION: We conclude that the association between hospitalisation, readmission, length of stay, and MM changes when sex and age group are considered. Differences were identified in the MM patterns associated with hospitalisation according to sex and age group.

RESUMO

INTRODUCTION: Dementia and cognitive decline are highly prevalent in later life and are growing public health concerns worldwide due to the increasing aging population. Individuals diagnosed with dementia have reduced mental function, resulting in social and cognitive skill deficits, increased dependence, and reduced autonomy-all of which are conditions associated with higher mortality rates. This systematic review aims to assess the effectiveness of treating dementia and cognitive decline with methylfolate. The main outcomes analyzed will be dementia and changes in cognitive function measured by different instruments in older adults treated with methylfolate. Secondary outcomes, such as inflammatory markers, plasma folic-acid levels, and total homocysteine, will also be assessed. METHODS AND ANALYSIS: This study will be carried out in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. This protocol is registered in the International Prospective Registry of Systematic Reviews, under the code CRD42021275755. We will include clinical trials conducted with older adults diagnosed with dementia or cognitive decline and treated with folic acid. The searches will be conducted on the PubMed, Scopus, and Embase databases, and the articles will be selected by reading their titles and abstracts first, followed by the full text. The quality of the selected studies will be assessed using GRADE and the risk of bias will be assessed using the Downs-and-Black method. ETHICS AND DISSEMINATION: The results will be presented at scientific conferences and disseminated by publishing a scientific article in an international English-language journal. We hope to find robust and significant evidence regarding the effectiveness of methylfolate supplementation in improving dementia symptoms and cognitive decline among older adults. By systematizing this evidence and possibly performing a meta-analysis study, we expect to significantly contribute to the treatment of this health problem, reduce mortality, and improve the quality of life and health of this population, boosting the development of medical protocols capable of reducing the financial effects of public health.

RESUMO

Introduction: fake news is one of the most frequently discussed subjects in the media, a problem that has become more evident with the rise of social and digital networks assuming the role of main information disseminators. From this perspective, it is important to be connected to a simple, fast communication vehicle that reaches many people. Media may also damage quality of scientific health communication with a negative impact on citizens' lives.Objective: in this context, this article aims to reflect on fake news and the coronavirus disease (COVID-19) pandemic, which has devastated the world since the beginning of 2020, particularly in Brazil.Methods: countless actions have been taken to contain what the World Health Organization (WHO) calls an "infodemic" that is present in everyday life, invading houses, mobile phones, and computers, in a time of social isolation and working from home. In this scenario, it is up to journalists, communicators, scientists, and health professionals jointly to share important information and to communicate about health and science in a responsible way.Conclusion: in a crisis it becomes essential that information reaches a large number of people and community leaders in order to influence people positively, which might help to save lives

RESUMO

Introduction: the COVID-19 pandemic has impacted on mortality and several adverse health outcomes. It has also affected education as schools and universities had to adapt to remote learning due to social isolation strategies.Objective: to analyze the pandemic's impact on medical education including undergraduate and graduate students and lecturers, as follow: i) teaching methods adopted by education institutes during shutdown, ii) students and lecturers' perceptions and iii) impacts on students' mental health.Methods: this systematic review includes the following study designs: cross-sectional, surveys, case-control, cohort, and clinical trials. The literature search was performed in four databases: PubMed, Scopus, Embase, and SciELO . The risk of bias and the quality of the evidence were evaluated.Results: a total of 1,576 articles were identified through searching databases, and 40 articles were included. We found the use of several teaching methods such as virtual platforms and social media, pre-recorded videos, discussion forums and others. Student's challenges related to interference during online study such as family distractions, lack of a study room, challenges with internet connectivity, difficulties in communication between students and lecturers, gaps encountered during clinical skills learning. Lecturers' challenges were difficulty in grasping students' progress and learning outcomes and the lack of experience in online teaching. Only five studies explored mental health issues of medical students and found the occurrence of depression, anxiety, and stress. However, their prevalence was not comparable due to the use of different diagnostic instruments.Conclusion: there has been a wide range of teaching methods implemented for distance learning of medical students globally. The perceptions of medical students about these methods and their impact were also varied. Infrastructure, family, and curriculum problems represented the greatest difficulties in adherence and satisfaction with distance learning. However, the flexibility of digital learning was one of the factors that helped reduce these problems. Regarding mental health, the occurrence of anxiety, depression, and stress was reported.

No entanto, sua prevalência não foi comparável devido ao uso de diferentes instrumentos de diagnóstico.Conclusão: existe uma ampla gama de métodos de ensino implementados para o ensino a distância de estudantes de medicina em todo o mundo. As percepções dos estudantes de medicina sobre esses métodos e seu impacto também foram variadas. Problemas de infraestrutura, família e currículo representaram as maiores dificuldades de adesão e satisfação com o ensino a distância. No entanto, a flexibilidade do aprendizado digital foi um dos fatores que ajudou a reduzir esses problemas. Em relação à saúde mental, foi relatada a ocorrência de ansiedade, depressão e estresse.

RESUMO

Background: The treatment for obesity, specifically severe obesity, is a challenge for health professionals and services. It requires a multidisciplinary and holistic approach covering the complexity and difficulties of incorporating healthy habits to prevent associated diseases and mortality. Individual intervention's methods are not enough to change eating habits. Objective: To describe and investigate the contribution of nutritional and food education as a complementary therapeutic approach in the treatment of individuals with severe obesity and their family members. Methods: A multidisciplinary team adopted a group approach. A different topic was addressed at each therapeutic meeting to assist in the nutritional treatment of obesity, such as diet and healthy habits i.e. barriers to lifestyle changes. The topics were developed based on different methodological and teaching approaches to facilitate adherence to non-drug treatment. Results: Overall, there was a greater understanding towards the adoption of healthy eating habits of the whole family, greater motivation to adhere to dietary changes and adoption of a more physical active lifestyle. This interventional educational support methodology had been accepted in such a positive way for patients and their relatives. Family member participation expands the possibilities of establishing necessary and lasting changes in the lifestyle of not only the patients, but their whole families. Conclusion: Health education actions constitute an important complementary therapeutic approach in promoting health and preventing complications in individuals with severe obesity. This article can be useful to enlarge the debate on the subject and face the challenges related to the effective treatment of obesity, notably severe obesity.

RESUMO

AIMS: Cardiovascular risk factors present a high prevalence and have an impact on the morbimortality of the elderly; however, studies evaluating the impact of cardiovascular risk factors in the elderly have had short follow-up times and have not allowed specific analyses of the effects of these factors in the aged population, including how they affect the survival of the elderly. This study aimed to analyse the survival of elderly individuals living in the community, considering the presence of cardiovascular risk factors. METHODS AND RESULTS: A prospective 10-year follow-up was initiated in 2008 with a cohort of 418 elderly people living in a community in Central Brazil. The Kaplan-Meier method and the Cox proportional hazards model were used to examine the association between survival and cardiovascular risk factors. The mean age of the participants was 70.6 (±7.1) years; most participants were hypertensive (81.6%) and participated in irregular physical activity (44%), and 43.3% smoked. After a mean follow-up of 8.38 (±2.82) years, 59.3% had survived and 34.1% had died; among the deaths, 14.1% were due to cardiovascular causes. Age [hazard ratio (HR) 1.067, 95% confidence interval (CI) 1.027-1.109], hypertension (HR 3.178, 95% CI 1.144-8.826), and smoking (HR 2.235, 95% CI 1.253-3.987) were confirmed as risk factors for reduced survival, whereas physical activity was a protective factor (HR 0.456, 95% CI 0.206-1.007). CONCLUSION: The results from this study highlight the need for educational policies towards hypertension and smoking prevention among elderly people, and participation in physical activity needs to be encouraged.

Realizada análise bivariada e múltipla com nível de significância de 5%. Resultados Participaram do estudo 212 idosos com prevalência de uso de medicamentos antitrombóticos de 27,8%. Os tipos mais utilizados foram: ácido acetilsalicílico (AAS) (n= 49; 83%), Clopidogrel (n=6; 10,1%) e Cilostazol (n=4; 6,7%). Os fatores associados foram: faixa etária de 70-79 anos (p<0,001) e a polifarmácia (p<0,001). Conclusão A proporção do uso de antitrombóticos foi alta entre os idosos, e os fármacos mais consumidos possuem risco de complicações e de interações medicamentosas. A vigilância deve ser maior naqueles com mais de 70 anos e em polifarmácia, sendo necessário empreender esforços para o acompanhamento clínico desses idosos em terapia antitrombótica farmacológica.

Abstract Objective To analyze the types and prevalence of use of antithrombotic drugs by older people and associated factors. Method A cross-sectional study of community-dwelling older people was carried out in the city of Goiânia, Midwest Brazil. The pharmacological classification of antithrombotic drugs was performed according to the Anatomical Therapeutic Chemical (ATC) classification. Bivariate and multivariate analyses were performed with a significance level of 5%. Results 212 older people participated in the study and the prevalence of antithrombotic drug use was 27.8%. The most used types were acetylsalicylic acid (ASA) (n= 49; 83%), Clopidogrel (n=6; 10.1%) and Cilostazol (n=4; 6.7%). Associated factors were the 70-79 years age group (p<0.001) and polypharmacy (p<0.001). Conclusion The proportion of antithrombotic use by the participants was high and the most used drugs posed a risk of complications and drug-drug interactions. Attention should be heightened in individuals aged >70 years and in use of polypharmacy and efforts must be made to clinically monitor these users of antithrombotic drugs therapy.

RESUMO

INTRODUCTION: Chronic pain is highly prevalent in older adults and can cause functional limitations, negatively affecting health and quality of life. Physical activity is a non-pharmacological approach used to prevent chronic pain as it promotes the release of endogenous opioids that block pain sensitivity. Therefore, we developed a systematic review protocol to analyse the relationship between physical activity and the occurrence and intensity of chronic pain in older adults. METHODS AND ANALYSES: The systematic review will search PubMed, Scopus and Embase databases. The inclusion criteria will be observational studies that had primary chronic pain as an outcome, including persistent and intermittent pain. The population will include older adults from the community, living in a long-stay institution, or in outpatient follow-up. There will be no restriction regarding the year of publication and articles published in Portuguese, English and Spanish will be analysed. Effect or impact measures will be quantified, including OR, HR, prevalence ratio, incidence ratio and relative risk with their 95% CIs. If the data allow, a meta-analysis will be performed. The results may help understand the impact of physical activity as a potential protection factor against the occurrence of pain later in life as well as promote strategic prevention plans and public policies that encourage this practice in older adults. ETHICS AND DISSEMINATION: Ethical approval is not required. The results will be disseminated via submission for publication to a peer-reviewed journal when complete. PROSPERO REGISTRATION NUMBER: CRD42021282898.

RESUMO

Vitamin D deficiency and insufficiency as well as low serum calcium levels can trigger negative health outcomes in women of childbearing age. Therefore, we aimed to estimate the prevalence of serum vitamin D and calcium deficiencies and insufficiencies and associated risk factors in Brazilian women of childbearing age and to assess whether there are differences in prevalence according to regions of the country and the presence or absence of pregnancy. The systematic literature review was performed using the following databases: PubMed, LILACS, Embase, Scopus, and Web of Science. Cross-sectional, cohort, and intervention studies were included. Among pregnant women, the prevalence of vitamin D deficiency ranged from 0% to 27% and of vitamin D insufficiency from 33.9% to 70.4%. Among non-pregnant women, the prevalence of vitamin D deficiency ranged from 0% to 41.7% and of vitamin D insufficiency from 38.5% to 69.3%. We found a high prevalence of vitamin D deficiency and insufficiency in women of childbearing age, with insufficiency affecting more than half of these women. The highest prevalence of vitamin D deficiency and insufficiency was observed in the South region. It was not possible to assess the prevalence and factors associated with calcium deficiency.

RESUMO

We estimated the impact of sarcopenia parameters on mortality risk and assessed its prevalence and associated factors in the older adults according to the European Working Group on Sarcopenia in Older People's 2010 (EWGSOP1) and 2018 (EWGSOP2) criteria. This was a 10-year follow-up cohort study. Low muscle mass (MM) was defined as low skeletal muscle mass index (SMI) using dual-energy X-ray absorptiometry (DXA), and low calf circumference (CC). Cox regression and the Kaplan-Meier method were performed. The prevalence of sarcopenia and associated factors were influenced by the MM measurement method and diagnostic criteria used [6.8% (SMI and EWGSOP2), 12.8% (CC and EWGSOP2; and SMI and EWGSOP1) and 17.4% (CC and EWGSOP1)]. While a low BMI was associated with sarcopenia regardless of the sarcopenia definitions, diabetes, and high TGs were associated with sarcopenia only when using the EWGSOP1 criteria. Low SMI increased mortality risk (EWGSOP1: HR = 2.01, 95% CI 1.03-3.92; EWGSOP2: HR = 2.07, 95% CI 1.05-4.06). The prevalence of sarcopenia was higher according to EWGSOP1 than EWGSOP2. A low BMI, diabetes, and high TGs were associated with sarcopenia. A low SMI doubled the risk of mortality in community-dwelling older adults.

RESUMO

There is insufficient evidence on the impact of abdominal obesity (AO) on mortality in older adults. Therefore, the objective to analyze the 10-year impact of AO, assessed using different diagnostic criteria, on all-cause, cardiovascular disease (CVD), and cancer mortality in older adults. In this prospective cohort study of older adults (≥60 years), sociodemographic, lifestyle, clinical history, laboratory test, and anthropometric data were analyzed. The considered were used for AO diagnostic: waist circumference (WC) of ≥88 cm for women and ≥102 cm for men; WC of ≥77.8 cm for women and ≥98.8 cm for men; and increased waist-to-hip ratio (WHR), being the highest tertile of distribution by sex. Multivariate Cox regression and Kaplan-Meier analyses were performed. A total of 418 individuals, with an average age of 70.69 ± 7.13 years, participated in the study. In the analysis adjusted for sex and age, WHR was associated with a high risk of all-cause mortality (p = 0.044). Both cutoff points used for the WC were associated with an increased CVD mortality risk. None of the AO parameters were associated with cancer mortality. An increased WHR was associated to a higher all-cause mortality risk factor, while an increased WC was a risk factor for a higher CVD mortality in older adults.

RESUMO

INTRODUCTION: Little is known about the impact of low muscle mass (MM) assessed by calf circumference (CC), arm circumference (AC), arm muscle circumference (AMC), and corrected arm muscle circumference (CAMC)-on mortality risk later in life. We aimed to investigate the impact of low MM assessed by CC, AC, AMC and, CAMC on all-cause, cardiovascular, and cancer mortality risk. METHODS: Data came from 418 older adults who participated in a 10-year follow-up prospective cohort study. Low MM was defined as a CC < 33 cm for women and < 34 cm for men and by the lowest tertile of AC, AMC, and CAMC stratified by sex. The log rank test, Kaplan-Meier curves, and Cox regression were used. RESULTS: There were 147 deaths: 49 related to CVD and 22 to cancer. A small CC (HR = 1.57, 95% CI, 1.12-2.20), AMC (HR = 1.61, 95% CI, 1.13-2.30) and CAMC (HR = 1.45, 95% CI, 1.03-2.04) were associated with all-cause mortality. A small CAMC was a protective factor for CVD mortality (HR = 0.46, 95% CI, 0.22-0.98). In the Kaplan-Meier analysis, older adults with LMM presented low all-cause mortality survival, with AC (p < 0.05), AMC (p < 0.005), CAMC (p < 0.002), and CC (p < 0.001). Cancer mortality was associated with low CAMC (p < 0.020). CONCLUSIONS: Low MM assessed by anthropometric measures (AC, AMC, CAMC and CC) increased the all-cause mortality risk. A small CAMC decreased the CVD mortality.

RESUMO

Multimorbidity is highly prevalent in older adults and can lead to hospitalisation. We investigate the prevalence, associated factors, and multimorbidity pattern associated to hospitalisation, readmission, and length of stay in the population aged 50 years and older. We analysed baseline data (2015-2016) from the ELSI-Brazil cohort, a representative sample of non-institutionalised Brazilians aged ≥ 50 years. In total, 8807 individuals aged ≥ 50 years were included. Poisson regression with robust variance adjusted for confounders was used to verify the associations with hospitalisation. Multiple linear regression was used to analyse the associations with readmission and length of stay. Network analysis was conducted using 19 morbidities and the outcome variables. In 8807 participants, the prevalence of hospitalisation was 10.0% (95% CI 9.1, 11), mean readmissions was 1.55 ± 1.191, and mean length of stay was 6.43 ± 10.46 days. Hospitalisation was positively associated with male gender, not living with a partner, not having ingested alcoholic beverages in the last month, and multimorbidity. For hospital readmission, only multimorbidity ≥ 3 chronic conditions showed a statistically significant association. Regarding the length of stay, the risk was positive for males and negative for living in rural areas. Five disease groups connected to hospitalisation, readmission and length of stay were identified. To conclude, sociodemographic variables, such as gender, age group, and living in urban areas, and multimorbidity increased the risk of hospitalisation, mean number of readmissions, and mean length of stay. Through network analysis, we identified the groups of diseases that increased the risk of hospitalisation, readmissions, and length of stay.

RESUMO

BACKGROUND: Much of the knowledge on the use of potentially inappropriate medications (PIM) in older adults is derived from cross-sectional studies, with little known about the risk factors over time. AIM: Longitudinal analysis was applied to estimate the occurrence and risk factors of PIM use among older adults in a 10-year follow-up. METHOD: Longitudinal study with 418 older adult residents of a capital city of Central-West Brazil. The PIM were classified according to the Beers criteria 2019. The usage rate was calculated at baseline (2008) and at the 10-year follow-up moment (2018). Analysis of predictors (sociodemographic, self-rated health, hospitalization, number of comorbidities, polypharmacy, diabetes, hypertension, hypercholesterolemia and nutritional status) was performed using Generalized Estimating Equation (GEE) models. RESULTS: Mean age at baseline was 70.6 years (SD 7.1) and 76% were women; 221 older adults took part in the follow up. The rate of PIM use was 50.4% at baseline and 57.5% at the 10-year follow-up. Multiple analysis showed that PIM use in the cohort was statistically higher in the older adults with a history of hospitalization (RRadj 1.20; 95% CI 1.01-1.40), with three or more diseases (RRadj 1.41; 95% CI 1.14-1.74), with polypharmacy (RRadj 1.81; 95% CI 1.47-2.24) and with diabetes mellitus (RRadj 1.24; 95% CI 1.05-1.47). CONCLUSION: A high level of potentially inappropriate medication use was observed, reaching 50% of the older adults, with a 7% increase in the prevalence over the 10-year follow-up period. Hospitalization, multimorbidities, polypharmacy and diabetes mellitus were associated with the use of these medications. Interventions for surveillance of the deprescribing process need to be encouraged to avoid potential harm caused by the use of medications.

RESUMO

BACKGROUND: Multimorbidity is defined as the presence of multiple chronic conditions in the same individual. Multimorbidity is more prevalent in older adults and can lead to several adverse health outcomes. METHODS: We systematically reviewed evidence from observational studies to verify the association between multimorbidity and hospitalization in older adults. Furthermore, we also aimed to identify whether it changes according to gender, advanced age, institutionalization, and wealth of the country of residence. We searched the PubMed, Embase and Scopus databases from December 2020 to April 2021. The analysed outcomes were as follows: hospitalization, length of stay and hospital readmission. RESULTS: Of the 6,948 studies identified in the databases, 33 were included in this review. From the meta-analysis results, it was found that multimorbidity, regardless of the country's wealth, was linked to hospitalization in older adults (OR = 2.52, CI 95% = 1.87-3.38). Both definitions of multimorbidity, ≥2 (OR = 2.35, 95% CI = 1.34-4.12) and ≥3 morbidities (OR = 2.52, 95% CI = 1.87-3.38), were associated with hospitalization. Regardless of gender, multimorbidity was associated with hospitalization (OR = 1.98, 95% CI = 1.67-2.34) and with readmission (OR = 1.07, 95% CI = 1.04-1.09).
