Morphometric analyses as a tool for the delimitation of a species complex of rupicolous Cattleya orchids from the Brazilian campos rupestres of Minas Gerais and Bahia

In the present study we perform a linear morphometric analysis to assess species delimitation in Cattleya caulescens, C. pabstii, and C. pfisteri, which constitute a species complex in Brazilian campos rupestres. For this purpose, we collected 18 linear measurement variables from flowers of 153 individuals in 11 populations from the three species in the Brazilian States of Minas Gerais and Bahia. We applied Principal Component Analysis (PCA), Canonical Variate Analysis (CVA) and cluster analysis to assess the morphological variation between populations. The analyses indicated a clear difference and cohese clusters of populations for each species, but one of the populations of C. pfisteri was divergent from the other populations. This difference is putatively explained by genetic data from other studies that suggest introgression from a species from a different series, C. sincorana, in this location. The differences between C. caulescens and C. pabstii reinforce the floristic differentiation of the orchid flora from the quartzitic mountains of Southern Minas Gerais in relation to the Espinhaço range to the north, as well as the development of a specialized orchid flora in the iron ore outcrops in Central Minas Gerais.

Rare Pleurotus species with veiled basidiomata from the Neotropics: neotypification of Pleurotus magnificus and epityfication of Pleurotus rickii

Knowledge of Pleurotus in Brazil dates back to the 19th century, when European mycologists studied and described numerous Neotropical taxa. Some of these long-described species remain poorly known, mostly due to the lack of recent records, detailed morphological descriptions, and molecular data. During field surveys in Southeast and Southern Brazil, specimens of two rare Pleurotus species with veiled basidiomata, i.e. P. magnificus and P. rickii, were collected. These species are recorded for the first time in the state of Santa Catarina, Brazil, and P. magnificus for the first time in the states of Minas Gerais, Paraná and São Paulo. Updated and detailed morphological descriptions are provided. DNA sequences of the ITS and nLSU molecular markers were obtained for both species, and phylogenetic analyses were conducted to explore their relationships within Pleurotus. A neotype is designated for P. magnificus, and a lectotype and epitype are designated for P. rickii.

Inventário e Análise da Arborização de praças no município de Campo Belo, MG

Due to the population growth in urban areas, it is necessary to rethink city planning. Parks, as accessible green spaces, play an important role in providing leisure, social interaction, education, and ecosystem services, contributing to improving quality of life.he objective was to carry out a qualitative and quantitative inventory of trees located in Cônego Ulisses and Menotti d’Áurea squares in Campo Belo, Minas Gerais. On-site data collection included identification, measurement (DBH, height, and cankers), and visual assessment (inadequate pruning, mechanical damage, apparent nutritional deficit, and pests). By cross-referencing the data, a classification of the trees' phytosanitary status was conducted. A total of 257 trees were found, with 70% belonging to native species and classified as large-sized. Only 3.5% of the trees showed apparent nutritional deficits. Regarding pests, 4.66% suffered attacks by termites, 5.44% by borers, and two individuals were attacked by caterpillars. It was observed that 10.89% had larger canker dimensions. It was noted that 43.97% of the trees were pruned irregularly, outside of the recommended technical standards, and three species suffered mechanical damage due to vandalism. It was identified that 52% of the trees classified under criterion III (precarious tree) were Pau Ferro. The inventory in the squares showed a predominance of native species, but planning for the planting of new specimens should respect specific diversity criteria. Monitoring needs to be carried out, and replanting planning should prioritize the replacement of precarious trees. Training should be provided for professionals performing pruning, and environmental education strategies should be developed for the population.

Insecticide-impregnated dog collars for the control of visceral leishmaniasis: evaluation of the susceptibility of field Lutzomyia longipalpis populations to deltamethrin.

Visceral leishmaniasis (VL) is a zoonotic disease caused by Leishmania infantum and transmitted by the sand fly Lutzomyia longipalpis. Dogs are the major domestic reservoir of L. infantum. To prevent the spread of the disease, dog collars impregnated with 4% deltamethrin have been effectively used in VL endemic areas. However, this approach may contribute to the emergence of insecticide resistance in sand flies. Therefore, it is important to characterize the susceptibility of different populations of Lu. longipalpis to deltamethrin in areas where insecticide-impregnated dog collars are used. Six field sand fly populations from Brazil were exposed to deltamethrin in CDC bottle bioassays at the diagnostic doses (DD) of 21.9μg/bottle and 30μg/bottle. For the dose-response (DR) experiments, doses of 1, 3, 5, 7, 9 and 11μg/bottle of deltamethrin were used to impregnate bottles; control group bottles were impregnated with acetone only. Each bottle contained an average of 20 sand flies, both male and female, and they were exposed to either deltamethrin or acetone for 60min. Based on the DD of 21.9μg/bottle, three populations were susceptible to deltamethrin. In contrast, two populations collected from the states of Ceará and Minas Gerais exhibited mortality rates of 94.9% and 95.7%, indicating possible resistance, and one population from the state of Ceará showed resistance, with a mortality rate of 87.1%. At the DD of 30μg/bottle, two populations from the states of Ceará and Piauí showed possible resistance, while the other four populations were susceptible. The resistance ratio (RR50) ranged from 2.27 to 0.54, and RR95 ranged from 4.18 to 0.33, indicating a low resistance intensity. This study established a DD for Lu. longipalpis using the CDC bottle bioassay. We found that Lu. longipalpis populations in three Brazilian states where insecticide-impregnated dog collars were used for VL control were susceptible to deltamethrin. However, one population in Ceará State was classified as resistant to deltamethrin. These results contribute to the current knowledge on sand fly resistance and surveillance, and highlight the need for a better understanding of the resistance mechanisms of Lu. longipalpis in areas where insecticide-impregnated dog collars have been widely used.

Diversity of Diptera and their parasitoids associated with Inga vera Willd. (1806) (Fabaceae) with new host record in Minas Gerais, Brazil

Diptera belonging to four different families, as well as four associated parasitoids were reared from fruits of Inga vera Willd. (Fabaceae) in Lavras, Minas Gerais, southeast Brazil. We collected 450 fruits from five trees of I. vera between 2020 and 2021 in various localities situated within the University Federal of Lavras. We reared specimens belonging to four different dipteran families: Anastrepha distincta Greene (Tephritidae), Asteromyia sp. (Cecidomyiidae), Drosophila zottii Vilela (Drosophilidae), and Neosilba pendula (Bezzi) (Lonchaeidae). Lopheucoilasp.(Hymenoptera: Figitidae) probably is a parasitoid of N. pendulawhereas Eupelmus sp. (Hymenoptera: Eupelmidae), and two species of Sycophila (Hymenoptera, Eurytomidae) appear to be parasitoids of Asteromyia sp.. We additionally conducted molecular characterization using the DNA barcoding locus for the majority of the species reared in this study. This study provides valuable insights into the biology and ecology of frugivorous flies in Brazil, and sheds light on potential biological control agents, enabling better management practices.

Impact of Credit in Rural Settlements of Minas Gerais, Brazil

Objective: The objective of this study is to analyze the impact of credit from the National Agrarian Reform Program (PNRA) on the income of family plots allocated by the National Institute of Agrarian Reform (INCRA) in the state of Minas Gerais, aiming to identify the correlation between the credit provided and the income generated. Theoretical Framework: Credit programs aimed at family farming enable the development of their activities in a sustainable, regulated manner and in compliance with environmental preservation, facilitating the construction and improvement of production systems according to each producer’s needs. Method: The study uses data collected from the RADIS/UFMT Project, in agrarian reform settlements in Minas Gerais state, Brazil, were processed and systematized using the Propensity Score Matching (PSM) regression model, with the use of Stata 16® software. Results and Discussion: The most accessed credit line by the beneficiaries was the Semi-arid line. The hypothesis that credit granted by the National Agrarian Reform Program (PNRA) is positively correlated with the income of plots allocated to families settled by INCRA is confirmed, showing an approximate 19% increase in the income of plots compared to those without access to credit. That is, for every R$1.00 of credit provided to the plot, there is an approximate increase of R$0.19 in income.

DESEMPENHO DA PRODUTIVIDADE DE MILHO A PARTIR DE APLICAÇÃO DE FUNGICIDA EM DIFERENTES ESTÁGIOS FENOLÓGICOS

Corn (Zea mays L.) is a crucial crop in terms of global production and economic value, but it is susceptible to fungal diseases such as common rust (Puccinia sorghi) and cercosporiosis (Cercospora zeae-maydis), which can reduce grain production and quality. Effective control of these diseases is vital for food security and agricultural economy. Proper management of corn fungal diseases depends on the plant's phenological stages, from planting to grain maturity. The application of fungicides at strategic moments during the plant's life cycle is essential to prevent infections and reduce disease impact. A study conducted in Patos de Minas, Minas Gerais, during 2023, evaluated the effect of fungicide application at different phenological stages of corn on final productivity. The results showed that fungicide application at multiple phenological stages (V4, V8, and VT) resulted in greater above-ground height, lower severity of fungal diseases, higher productivity, and uniform stalk diameter compared to the control treatment. This integrated disease management method proved effective in protecting plants against fungal diseases, promoting healthier and more vigorous growth, and increasing final corn productivity. These findings highlight the importance of fungicide application at strategic moments in the corn development cycle to maximize productivity and promote more efficient and sustainable agriculture.

A key for the 14 known species of the genus is provided.

Abstract 4136776: Prognostic Value of Resting Heart Rate and Heart Rate Variability in the 12-lead Electrocardiogram: Mortality Data From the CODE Nationwide Database

Introduction: Resting Heart Rate (HR) and Heart Rate Variability (HRV) reflect autonomic control, and are implicated as prognostic factors. We aimed to evaluate the prognostic value of HR and HRV in a cohort from a nationwide telemedicine network. Methods: We assessed unique ECGs recorded from patients ≥16 years-old, from the tele-ECG database of the Telehealth Network of Minas Gerais, Brazil, between 2010 and 2017. Variables of interest were HR and standard deviation of normal RR intervals (SDNN). Self-informed data were collected: sex, age, risk factors (hypertension, dyslipidemia, diabetes, smoking) and comorbidities (myocardial infarction, Chronic Obstructive Pulmonary Disease, and Chagas disease). Outcomes of interest were all-cause and cardiovascular mortality, assessed by ICD codes reported in death certificates, through linkage with the Mortality Information System. Cox regression was applied to evaluate the association between HR and HRV and the outcomes, in 4 models: 1. Unadjusted; 2. Adjusted for sex and age; 3. Model 2 + risk factors + clinical comorbidities; 4. Model 3 + HRV or HR, respectively. Results: At total 992.611 individuals were included, median age of 55 years, 60% women. In 6 years, there were 33.292 deaths (3,37%), 21% due to cardiovascular causes. Patients who died had higher prevalence of all risk factors and comorbidities, as well as higher HR: 76 (IQR 66-87) vs. 74 (IQR 65-83) bpm, p<0.001 and lower HRV: 84 (IQR 51-127) vs. 114 (IQR 74-153), p<0.001. After adjustments (model 4), all HR quartiles were independently associated a progressively increased risk of all-cause mortality, being 88% higher for the 4 th quartile (HR=1.88 (95%CI 1.77–1.89). Similarly, the 1 st and 2 nd HRV quartiles remained associated with increased all-cause mortality (1 st quartile HR=1.42 (95%CI 1.37–1.47) in the final model. For cardiovascular mortality, HR was also an independent predictor, with a progressively higher risk, with a 77% increase (HR=1.77 95%CI 1.65–1.91) in the 4 th quartile. HRV was also an independent predictor of cardiovascular death, with a 33% risk increase (HR=1.33, 95%CI 1.23–1.44) for the 1 st quartile. Male gender, age, and all risk factors and comorbidities were also independent predictors of all-cause and cardiovascular mortality. Conclusions: In a large cohort of Brazilian adults, baseline HR and HRV were independent predictors of all-cause and cardiovascular mortality, after adjustment for clinical variables and autonomic indexes.

Abstract 4138273: Acceptability and Gain of Knowledge of Community Educational Tools About Rheumatic Heart Disease Integrated With Screening In Low-Income Settings

Background: Rheumatic heart disease (RHD) causes 305,000 premature annual deaths, and education is one of the strategies to diminish disease burden. International RHD foundations aim do provide preventive and control efforts for RHD. We aimed to assess the acceptability and gain of knowledge of a series of education flipcharts presented during screening programs in high-burden areas of Brazil. Methods: Four flipcharts (“Introduction to rheumatic fever (RF) and RHD”, “RHD and pregnancy”, “RHD and surgery” and “RHD community awareness”) were developed over 3 years and taught during 36 months to patients, community, health and education professionals in Minas Gerais state. Training included in-person interactions and virtual workshops. Pre and post-training questionnaires were applied through an online and printed surveys in 2021 and 2022, and post-education evaluations were conducted from January 2023 to April, 2024. Results: Flipchart training was successfully delivered to 112 education professionals, 574 health providers and 598 community members (N=1284): 899 (70%) were enrolled in primary care, and 1109 (86%) responded the surveys. Among respondents of the survey for health and education professionals (N=589), 240 (41%) had been educated about RHD in the previous year. 569 (96%) learned any new information; the content was all new for 21 (4%). Nearly all professionals reported that flipcharts could improve patients’ lives (571, 97%) and felt confident to use the tool with someone with no knowledge about RHD (533, 91%); 86% of the teachers said they would use flipcharts as educational tools. In the survey for community / schoolchildren (N=520) only 128 (25%) respondents had previous education on RHD, 510 (98%) reported that learned new information, and content was completely new for 242 (47%). A total of 430 (83%) individuals reported that they will discuss RHD with families and community. All qualitative written reports were positive. In 2021/2022, 218/485 (45%) health and education professionals responded the pre/post questionnaire. Knowledge about RHD increased after training: RF as the cause of RHD (56% vs 86%), use of Benzathine Penicillin G (50% vs 97%), frequency of antibiotic prophylaxis (32% vs 90%) and overall moderate or expert understanding of RF or RHD (30% vs 82%). Conclusion: Flipchart educational sessions about RHD had a very positive acceptability in high-risk Brazilian populations, with remarkable gain of knowledge for health professionals.

Understanding American tegumentary leishmaniasis in urban Montes Claros, Brazil: insights from clinical, immunological and therapeutic investigations.

The challenge of American tegumentary leishmaniasis (ATL) continues in Brazil, presenting a persistent public health issue despite initiatives aimed at public outreach, vector control and health education. To gain a deeper understanding of this disease, a study was conducted in an endemic region located in the northern region of the state of Minas Gerais, Brazil. The study monitored 30 resident patients diagnosed with ATL, using serum samples from 6 healthy individuals as controls. The localized cutaneous form of the disease was found to be predominant, with lesions appearing on various parts of the body and the majority of the affected individuals being male. The study found significantly higher levels of IgG anti-α-Gal antibodies in ATL-infected patients compared to healthy individuals. Treatment of 19 patients with meglumine antimoniate resulted in limited improvement in symptoms for most. Nonetheless, the study found that 12 patients who completed treatment with epithelialization of the lesions showed a significant decrease in IgG anti-α-Gal antibodies, indicating potential applications of this antibody in the diagnosis and monitoring of the disease. The study also identified Leishmania species in 7 analysed patients, revealing 6 cases infected by Leishmania braziliensis and 1 by L. infantum, with a significant difference in the anti-α-Gal responses. The findings of the study emphasize the urgent need for the development of human vaccines and innovative treatment strategies adapted to the diversity of Leishmania species causing cutaneous leishmaniasis and individual patient responses to improve the clinical management of ATL in Brazil and similar endemic regions.

The Brazilian State Water Resources Councils: diagnosis of civil society participation through criteria of access to information, parity, and decision-making procedures

The aim of the article was to investigate whether the Brazilian State Water Resources Councils, including the Federal District, ensure civil society participation through access to information, parity, and decision-making procedures. In this context, verification criteria were selected, with maximum score of 1 point assigned based on their suitability for the Councils, which were classified in terms of participation adequacy. The states that were deemed suitable, in descending order, were: Paraíba (1st position), Mato Grosso do Sul, Minas Gerais, and São Paulo (2nd position), Amazonas, Pará, Paraná, Rio de Janeiro, Rio Grande do Sul, Rondônia, and Santa Catarina (3rd position), Bahia, Ceará, Federal District, Espírito Santo, and Mato Grosso (4th position), Rio Grande do Norte and Tocantins (5th position), and Alagoas (6th position). The states deemed unsuitable were: Acre and Pernambuco (7th position), Piauí and Roraima (8th position), Goiás and Sergipe (9th position), and Amapá and Maranhão (10th position). As for the criteria, the ones that scored the highest were: the presence of the website and Internal Regulations of the Councils, decision-making by the Council in plenary sessions, the presence of Meeting Minutes on the website, identification of the Technical Chambers of the Councils on these channels, adherence to the regular meeting schedule, identification of the members who make up the Councils, and parity among the three sectors that constitute them. It was concluded that the State Water Resources Councils need to ensure equal participation for civil society members in their discussions and deliberations as well as provide public access to the information generated.

Drug dispensing in public community pharmacies: evidence from the MedMinas project

BackgroundDrug dispensing is a service provided by pharmacists to ensure the supply of medications and other health-related products. However, despite the importance of dispensing services, Public Community Pharmacies (PCP) in Brazil still focus on the control and distribution of medicines and supplies. Thus, this paper aims to evaluate how the pharmacists in charge conduct and the challenges they encounter in dispensing services in PCP.MethodsThis is a mixed methods study, with a representative sample of 26 municipalities (whose populations vary between 37,784 and 409,341 inhabitants) in the state of Minas Gerais, Brazil. Data collection took place between April and October 2019 and included interviews and documentary research. Quantitative data analysis was carried out using descriptive statistics and qualitative data was subjected to thematic content analysis.Results24 dispensing services were analyzed. The PCP had, on average, two active pharmacists and operated full-time (40 h per week). In relation to dispensing services, the most frequently mentioned steps were checking the adequacy of the prescription received, followed by providing counseling to the user about the medicines, mainly regarding administration, storage and disposal. The results highlighted a need for improvements in terms of infrastructure, workforce and the pharmacist’s work process.ConclusionIt is necessary to invest and to design improvement strategies in dispensing services, especially regarding physical infrastructure, human resources and work processes.

Radiocarbon dating and isotopic paleoecology of Notiomastodon platensis (Mammalia: Proboscidea) from the late Pleistocene of Minas Gerais, Brazil

Proboscidea is a group of large mammals abundant in the fossil record and in Brazil it is represented by Notiomastodon platensis (Ameghino, 1888). To improve the understanding on its taxonomy, chronology, annual diet, and habitats paleoenvironmental aspects, we conducted a morphological description, absolute dating, and analysis of stable isotopes of carbon and oxygen (δ13C and δ18O) in Notiomastodon' remains from the northern (Norte de Minas) and western (Triângulo Mineiro) mesoregions of Minas Gerais State, Brazil. The material includes isolated teeth, mandibular portions, and postcranial bones at different levels of fragmentation, associated with at least eight adults and one juvenile. The only individual from Triângulo, found in Campina Verde municipality, was dated at 27,715–27,903 Cal yr BP. It presented a mixed diet based on C4 plants (piC4 = 90 %; δ13C = 0.5 ‰), which implies the occupation of an open environment, mostly pasture. The region was relatively humid (δ18O = 24.7 ‰), which is supported by the existence of humidity corridors in the Amazon region. A similar phytophysiognomy was inferred for the Norte de Minas region between at least 21,966–22,279 Cal yr BP and 18,944–19,157 Cal yr BP. However, one specimen showed a different δ13C value (piC3 = 0.87 %; δ13C = −10.2 ‰). This indicates it lived in a transitional environment between low-density forest and arboreal savannah. This likely occurred during a period that favored the expansion of trees and shrubs. The region underwent climate change, from relatively humid conditions (δ18O = 25.6 ± 0.2 ‰) to expressively dry (δ18O = 34.6 ‰) between the dated periods, a change corroborated by some palynological data. The multiannual paleoecological analysis, based on sequential sampling of three dentin layers of an incisor, indicated the relative stability of vegetation and climate despite fluctuations in hydrology. The perceived disassociation between vegetation dynamics and local hydrology corroborates the idea that factors other than precipitation may play a significant role in the environmental dynamics of the Cerrado biome.

Uncovering the rich amphibian fauna of two semideciduous forest fragments in southwestern Bahia, Brazil.

Fauna inventories reduce biodiversity knowledge gaps by providing comprehensive data on species distribution, richness, and abundance. Furthermore, they identify undocumented species and enhance understanding of ecosystem dynamics and conservation needs. The richness and abundance of amphibian species were studied in two Semideciduous Seasonal Forest areas in the municipalities of Potiraguá (Serra Azul) and Itarantim (Serra do Mandim) in southwestern Bahia, Brazil. Active visual and acoustic surveys were conducted in 24 forest interior transects, two stream transects, and two permanent ponds investigated in the study area. Opportunistic encounters during team movements were also recorded. The richness was 46 amphibian species distributed in 14 families and 26 genera. Approximately half of the species were shared between the two areas, while 11 species were exclusive to Serra Azul and another nine were found only in Serra do Mandim. Cluster analysis for 42 locations in Atlantic Forest, Caatinga, and Cerrado, in a presence/absence matrix with 216 species, revealed that the composition of the amphibians found in Serra do Mandim and Serra Azul is similar to other sampled locations in the northeastern region of Minas Gerais, close to the study site, which are considered transitional between the Atlantic Forest and the Caatinga. Our results demonstrate that the remaining forest fragments in the region, although small and isolated, still sustain a high richness of amphibians with species restricted to the Atlantic Forest and Bahia, such as Bahiusbilineatus, Ololygonstrigilata, Aplastodiscusweygoldti and Vitreoranaeurygnatha, and others considered typical of the Caatinga, such as Leptodactylustroglodytes and Physalaemuscicada. Additionally, we sampled potential new species, filled occurrence gaps, and expanded the geographical range of Pseudisfusca.

UAV imaging for spectral characterization of Coffee Leaf Miner (Leucoptera coffeella) infestation in the Cerrado Mineiro region

Abstract. Brazil, the world's largest coffee producer, faces challenges managing the coffee leaf miner (Leucoptera coffeella), a significant pest. This study suggests remote sensing for pest control decisions. Two experimental areas in the Cerrado region of Minas Gerais State were analyzed to spectrally characterize infested plants and estimate the number of mines per plant. Results show the ability to differentiate infested plants with greater reflectance variance in the near infrared at 850nm. The performances of the three machine learning algorithms were compared. Determining the number of mines in the group of most infested plants demonstrated slightly higher precision, achieving an RMSE of 22.69% using the Support Vector Machine algorithm. Conversely, the group of least-infested plants obtained the best result with the Random Forest algorithm, achieving an RMSE of 32.47%. These promising results indicated that CLM can be detected using aerial multispectral imaging data.

Sociodemographic, economic, and academic factors linked with resilience in university students during covid-19 pandemic: a Brazilian cross-sectional study

BackgroundResilience is a crucial factor in students’ mental health, playing an important role in their successful adaptation to the academic environment. However, there is a lack of understanding about resilience and its associated factors in students from different undergraduate courses. This study aimed to describe the resilience profile of undergraduate students from various courses in Brazil and identify sociodemographic, economic, and academic factors associated with resilience.MethodsThis study has data from a cross-sectional multicenter study involving undergraduate students from eight Federal Institutions of Higher Education in Minas Gerais, Brazil. The dependent variable was resilience, measured using the Connor-Davidson Resilience Scale (CD-RISC) 10-item version, with sociodemographic, economic, and academic factors considered independent variables. Data was collected virtually via a self-administered questionnaire between October 2021 and February 2022 (during the covid-19 pandemic). Independent samples t-tests and ANOVAs were conducted to compare resilience scores between independent variables, and Tukey’s post-hoc test was performed when necessary. Multiple linear regression was performed to create three models.Results8,650 undergraduate students were included in this study. The average score on the resilience scale was 19.86 ± 8.15, with a normal distribution. The respondents ranged from 18 to 71 years old, averaging 23.9 ± 6.33. Being female, not having a religious belief, having low per capita family income, having had a decrease in the family income, not being heterosexual, or having the head of the family with a low education level were the main factors associated, individually, with low resilience scores in the sociodemographic and economic multiple linear regression model constructed. Being from linguistics, letters and arts courses, being enrolled in fewer subjects, or being from UFMG were the main factors associated, individually, with low resilience scores in the academic multiple linear regression model constructed.ConclusionsThe study’s findings revealed that sociodemographic, economic, and academic variables were significantly associated with resilience scores in undergraduates from Minas Gerais during the covid-19 pandemic. These findings can help universities develop target strategies to promote students’ resilience and reduce the risk of poor mental health among this population.

Multimorbidity patterns and socioeconomic conditions: Association with functional limitations in older adults

This study evaluated the association between multimorbidity patterns and socioeconomic conditions with functional limitation in individuals aged 60 years or older from the State of Minas Gerais, Brazil. This was a cross-sectional study with data from the last National Health Survey. Dependent variables were functional limitations in basic (BADL) and instrumental activities of daily living (IADL). The independent variables were multimorbidity patterns and socioeconomic conditions. Multimorbidity patterns were defined using an exploratory factor analysis. The association between multimorbidity patterns and dependent variables was tested using logistic regression models adjusted for covariates. Multimorbidity patterns were associated with limitations in BADL and IADL, except for the metabolic profile for IADL. Individuals with higher income had lower chances of being limited in BADL. Older adults with a higher level of education and income had lower chances of limitation in IADL. Multimorbidity patterns and socioeconomic conditions were associated with limitations in BADL and IADL.
