Abstract

This study aimed to verify the prevalence and socioeconomic and health factors associated with morbidity among community-dwelling elderly. This is an analytical and cross-sectional survey conducted in 2012 with 1,691 elderly from Uberaba-MG. A tool structured for socioeconomic data and self-reported morbidities was used along with the Abbreviated Geriatric Depression, Katz and Lawton-Brody scales. We proceeded to a descriptive analysis and linear regression (p < 0.05). A high percentage (88.3%) of elderly reported two or more morbidities, with higher prevalence for systemic arterial hypertension (61.9%) and back problems (48.6%). Female gender (β = 0.216; p< 0.001), functional disability in basic (β = 0.240; p < 0.001) and instrumental activities of daily living (β = 0.120; p < 0.001) and indicative of depression (β = 0.209; p < 0.001) were associated with the highest number of morbidities. The presence of two or more comorbidities and the association with socioeconomic and health variables show the need for monitoring and control actions of the factors that interfere in the elderly in this condition.

Introduction

The demographic and epidemiological transition process has resulted in a change in the population profile and in morbimortality, especially in increased chronic noncommunicable diseases (CNCDs)¹1 Brasil.

In a study carried out with elderly in Teófilo Otoni (MG), 83.1% reported having at least one chronic disease, and being non-white, low schooling, medication consumption, use of dental prosthesis, need for public health services, third-party dependence and female gender were factors associated with diseases such as hypertension and diabetes mellitus⁹9 Pimenta FB, Pinho L, Silveira MF, Botelho ACC.

In Brazil, CNCD surveillance facilitates the understanding of the distribution, magnitude, trends and main risk factors of the population, as well as the identification of the social, economic and environmental determinants, in order to plan, implement and evaluate prevention and control actions¹1 Brasil.

http://bvsms.saude.gov.br/bvs/publicacoe... . In line with this strategy, health surveys include the National Health Survey (PNS), which monitors the health conditions of the Brazilian population by means of a survey considering several realms, including chronic morbidity⁵5 Instituto Brasileiro de Geografia e Estatística (IBGE).

It should be noted that increased chronic diseases tend to accompany the rapid growth of the Brazilian elderly population, and, thus, the development of a new model of health care for this group becomes relevant¹1 Brasil.

In addition, the understanding of health professionals of socioeconomic, behavioral and educational challenges of the elderly and their families⁹9 Pimenta FB, Pinho L, Silveira MF, Botelho ACC.

In this perspective, strengthening health services, aiming at increasing interventions for the prevention and control of chronic diseases and bettering the health education process are strategies for the development of care with a comprehensive approach to the health of individuals in this condition¹1 Brasil.

When considering the increased number of elderly people in the Brazilian population and the impact of CNCDs, it becomes essential to understand the main factors associated with this process in order to contribute to public policies’ actions. Thus, this study aimed to verify the prevalence and socioeconomic and health factors associated with morbidities among the elderly in the municipality of Uberaba (MG) in 2012.

Methods

This is a household survey with a quantitative, cross-sectional and analytical approach conducted in 2012 with elderly residents in an urban area of the city of Uberaba (MG).

In 2005, the Municipal Zoonoses Center provided us with a list containing the full name and address of the elderly to make up the sample. For the selection of the elderly, 95% confidence interval, 80% test power, a margin of error of 4.0% for the interval estimates and an estimated proportion of π = 0.5 were considered for the proportions of interest. In 2012, interviewers visited the households of the 2,116 elderly, of whom 1,691 were interviewed according to the inclusion criteria established, which were to be 60 years of age or older, to reside in the urban area of the municipality and not having a cognitive decline. Exclusions and/or losses were related to deaths (265) and cognitive decline (160).

Ten interviewers were selected for data collection and were trained by the researcher responsible regarding the elderly approach, application of questionnaires and the ethical aspects involved in the research. Interviews were reviewed by supervisors, who checked for incomplete fields or inconsistent responses. If these situations occurred, the questionnaire was returned to the interviewer who contacted the elderly for adequate completion.

The cognitive status was evaluated through the Mini Mental State Examination (MMSE), based on the translated version validated for Brazil¹¹11 Bertolucci PHF, Brucki SMD, Campacci SR, Juliano Y. O mini-exame do estado mental em uma populaçäo geral: impacto da escolaridade. Arq Neuropsiquiatr 1994; 52(1):1-7. to verify whether the elderly had cognitive decline, one of the inclusion criteria of this study. The MMSE has a total score ranging from zero to 30 points, and cutoff points for cognitive decline vary according to elderly schooling: 13 points for illiterate, 18 points for 1-11 years schooling and 26 points for over 11 years schooling¹¹11 Bertolucci PHF, Brucki SMD, Campacci SR, Juliano Y. O mini-exame do estado mental em uma populaçäo geral: impacto da escolaridade. Arq Neuropsiquiatr 1994; 52(1):1-7..

A form prepared by the Public Health Research Group was used for the characterization of sociodemographic and economic data and identification of self-reported morbidities.

Functional disability for basic activities of daily living (BADL) was measured by means of the Index of Independence in Activities of Daily Living (Katz Scale) adapted to the Brazilian reality¹²12 Lino VTS, Pereira SEM, Camacho LAB, Ribeiro Filho ST, Buksman S. Adaptação transcultural da Escala de Independência em Atividades de Vida Diária (Escala de Katz). Cad Saude Publica 2008; 24(1):103-112.. This scale consists of six items that measure individual performance in self-care activities, such as bathing, dressing, going to the bathroom, lying down and getting out of bed, eating and controlling urination and/or evacuation functions¹²12 Lino VTS, Pereira SEM, Camacho LAB, Ribeiro Filho ST, Buksman S. Adaptação transcultural da Escala de Independência em Atividades de Vida Diária (Escala de Katz). Cad Saude Publica 2008; 24(1):103-112.. Limitations in instrumental activities of daily living (IADL) were assessed by the Lawton-Brody Scale (1969) adapted for Brazil¹³13 Virtuoso Júnior JS, Guerra RO. Incapacidade funcional em mulheres idosas de baixa renda. Cien Saude Colet 2011; 16(5):2541-2548.. This scale consists of nine items, such as using the telephone, going to distant places using transportation, shopping, preparing meals, cleaning and tidying up the house, taking medications and dealing with finances¹³13 Virtuoso Júnior JS, Guerra RO. Incapacidade funcional em mulheres idosas de baixa renda. Cien Saude Colet 2011; 16(5):2541-2548.. Functional disability is when the elderly had one or more partial and/or total dependence for both BADL and IADL.

The indicative of depression was assessed using the Abridged Geriatric Depression Scale. This scale is used for the screening of the indicative of depression and was proposed by Yesavage in 1986 and validated in Brazil by Almeida and Almeida¹⁴14 Almeida OP, Almeida SA. Confiabilidade da versão brasileira da Escala de Depressão em Geriatria (GDS) versão reduzida. Arq Neuropsiquiatr [online]. 1999 [acessado 2015 Set 11]; 57(2b):421-426. Disponível em: http://www.scielo.br/pdf/anp/v57n2B/1446.pdf
http://www.scielo.br/pdf/anp/v57n2B/1446... , consisting of 15 questions with objective answers (yes or no). Positive screening for indicative of depression was considered when the score was higher than five points.

The following variables were included for the study: gender; age group, in years (60-69, 70-79, 80 years and over); marital status (never married or lived with partner, married, separated/divorced and widower); schooling, in years of study (illiterate, 1-3, 4-7, 8, 9-10 and 11 and over); individual monthly income, in minimum wages (MW) (no income, less than 1 MW; 1 MW, 2-3 MW, 4-5 MW, greater than 5 MW; self-reported morbidities (rheumatism, arthritis/arthrosis, osteoporosis, asthma/bronchitis, tuberculosis, embolism, systemic arterial hypertension, poor circulation, heart problems, diabetes, obesity, stroke, Parkinson’s, urinary incontinence, fecal incontinence, intestinal constipation, sleep problems, cataract, glaucoma, back problems, kidney problems, accident/trauma sequelae, malignant tumors, benign tumors, vision problems and others), number of self-reported morbidities, indicative of depression (yes/no), functional disability for BADL (dependent/independent) and IADL (dependent/independent).

After data collection, an electronic database was built in the Excel program, processed in a microcomputer and double entered by two people. The existence of duplicated records and the consistency of fields were verified. In the case of inconsistent data, the original interview was retrieved for correction. Subsequently, the database was imported into the software “Statistical Package for Social Sciences” (SPSS), version 17.0, for data analysis.

Descriptive statistical analysis was performed for the categorical variables from absolute and percentage frequencies; and means and standard deviations for the numerical ones. For the preliminary bivariate analysis, t-student tests were used to compare the number of self-reported morbidities with the categorical variables (gender, income, functional disability for basic and instrumental activities of daily living and indicative of depression) and Pearson’s coefficient of correlation for the variables age and schooling. Tests were considered significant when p < 0.10.

The variables of interest were inserted in the multiple linear regression model according to the inclusion criterion (p < 0.10) established in the preliminary bivariate analysis. The variables age, schooling and dichotomies were quantitative, whereas income, functional disability for basic and instrumental activities of daily living and indicative of depression (independent variables) were dichotomous. Factors associated with the number of self-reported morbidities (dependent variable) were identified using the linear regression model (enter method), considering a significance level of 5% (p < 0.05). We considered the necessary minimum prerequisites including residual analyses (normality, linearity and homoscedasticity) and multicollinearity.

The project was submitted to the Human Research Ethics Committee of UFTM and was approved. The interviewers approached the elderly of the study at home; they showed them the Informed Consent Form and, after clarifications, participants were asked to sign said form to start the interview.

Results

Among the 1,691 respondents, mean age was 72.53 years (SD = ±7.4); and most were female, aged 70-79 years, had 4-7 years of schooling, were married and with individual monthly income of one minimum wage, Table 1.

Table 1 shows the distribution of the frequency of sociodemographic and economic variables of the elderly.

It was evidenced that 3.4% (n = 57) of the elderly reported no morbidity, while 8.2% (n = 139) had one and 88.3% (n = 1494) two or more. The most prevalent morbidities were systemic arterial hypertension and back problems, Table 2.

Table 2 shows the distribution of morbidities self-reported by the elderly.

Regarding factors associated with self-reported morbidities, the variables of the preliminary bivariate analysis submitted to the multivariate analysis according to the inclusion criterion established (p < 0.10) were female gender (p < 0.001), age (p = 0.017), schooling (p = 0.001), functional disability for BADL (p < 0.001) and IADL (p < 0.001) and indicative of depression (p < 0.001).

The variables included in the multivariate linear regression model are shown in Table 3. The highest number of self-reported morbidities was associated with female gender (p < 0.001), dependence for BADL (p < 0.001) and IADL (p < 0.001) and indicative of depression (p < 0.001). The necessary minimum prerequisites considered were met and the coefficient of determination corresponded to 0.217.

Table 3 shows the final linear regression model for the factors associated with the number of morbidities in the elderly.

Discussion

With age, the presence of morbidities is a frequent condition for the elderly¹⁵15 Marengoni A, Angleman S, Melis R, Mangialasche F, Karp A, Garmen A, Meinow B, Fratiglioni L. Aging with multimorbidity: a systematic review of the literature. Ageing research reviews 2011; 10(4):430-439.. In Brazil, the number of elderly individuals aged 65 years and over who report having at least one disease is 79.1%¹1 Brasil. Ministério da Saúde (MS).

http://bvsms.saude.gov.br/bvs/publicacoe... . In an international systematic review, the presence of two or more morbidities showed percentage variations between 55% and 98% in this age group¹⁵15 Marengoni A, Angleman S, Melis R, Mangialasche F, Karp A, Garmen A, Meinow B, Fratiglioni L. Aging with multimorbidity: a systematic review of the literature. Ageing research reviews 2011; 10(4):430-439.. National research carried out in Teófilo Otoni (MG) found that 83.1% of the elderly reported at least one morbidity⁹9 Pimenta FB, Pinho L, Silveira MF, Botelho ACC.

http://www.scielosp.org/pdf/csc/v20n8/14... ; in Maceió (AL), the highest percentage (60.1%) was observed among those who had one or more morbidities¹⁶16 Santos MB, Ribeiro SA. Dados sociodemográficos e condições de saúde de idosas inscritas no PSF de Maceió, AL. Revista brasileira de geriatria e gerontologia 2011; 14(4):613-624.; and in Porto Alegre (RS), 47.5% reported two or more diseases¹⁷17 Silva AR, Snaolin V, Nogueira EL, Loureiro F, Engroff P, Gomes I. Doenças crônicas não transmissíveis e fatores sociodemográficos associados a sintomas de depressão em idosos. J Bras Psiquiatr 2017; 66(1):45-51.. In international research, most of the elderly reported two or more diseases in Switzerland (70.4%)¹⁸18 Rizzuto D, Melis RJF, Angleman S, Qiu C, Marengoni A.

This worldwide overview of a high percentage of CNCDs among the elderly population results in an increased burden of chronic diseases and, thus, the need for a new model of health care emerges¹1 Brasil. Ministério da Saúde (MS). Plano de ações estratégicas para o enfrentamento das doenças crônicas não transmissíveis (DCNT) no Brasil 2011-2022. 2011 (Série B. Textos Básicos de Saúde).

http://bvsms.saude.gov.br/bvs/publicacoe... . As a result, the “Plan of strategic actions for coping with chronic noncommunicable diseases (CNCD) in Brazil” was developed to promote interventions aimed at reversing the negative impact of morbidities and their risk factors, as well as improving health care, early detection and timely treatment¹1 Brasil. Ministério da Saúde (MS). Plano de ações estratégicas para o enfrentamento das doenças crônicas não transmissíveis (DCNT) no Brasil 2011-2022. 2011 (Série B. Textos Básicos de Saúde).

http://bvsms.saude.gov.br/bvs/publicacoe... .

It should be noted that, despite divergence between percentages referring to the number of diseases, there is a small number of elderly people who are not included in this epidemiological transition setting and, thus, report not having CNCDs. This occurs both at national (2.2%)¹⁶16 Santos MB, Ribeiro SA. Dados sociodemográficos e condições de saúde de idosas inscritas no PSF de Maceió, AL.

However, there is still a shortage of investigations about the increased number of morbidities and their associated factors in the scientific literature¹⁵15 Marengoni A, Angleman S, Melis R, Mangialasche F, Karp A, Garmen A, Meinow B, Fratiglioni L.

Ministério da Saúde (MS). Envelhecimento e saúde da pessoa idosa. Brasília: MS; 2006.. On the other hand, the prevalence of back-related diseases, although considered high, decreased in the last decade²⁹29 Instituto Brasileiro de Geografia e Estatística (IBGE).

The high number of elderly people with chronic diseases exposes the importance of an organization of health services, by managers and researchers, with a view to developing prevention strategies and interventions for the age group in this condition³⁰30 Veras RP. Estratégias para o enfrentamento das doenças crônicas: um modelo em que todos ganham. Revista Brasileira de Geriatria e Gerontologia 2011; 14(4):779-778.. This set of actions occurs due to the need for continuous care that chronicity entails to the health of the elderly, causing health professionals to disassociate themselves from a care structure geared to acute care³⁰30 Veras RP. Estratégias para o enfrentamento das doenças crônicas: um modelo em que todos ganham. Revista Brasileira de Geriatria e Gerontologia 2011; 14(4):779-778..

This diverse morbidity prevalence can be justified by the different methodologies used¹⁹19 Van Den Bussche H, Koller D, Kolonko T, Hansen H, Wegscheider K, Glaeske G, von Leitner EC, Schäfer I, Schön G.

BMC Public Health 2011; 11(1):1-9., and loco-regional specificities, resulting in difficulty to compare studies.

Most studies analyze the amount of morbidities according to a pre-established list⁹9 Pimenta FB, Pinho L, Silveira MF, Botelho ACC. Fatores associados a doenças crônicas em idosos atendidos pela Estratégia de Saúde da Família. Cien Saude Colet [online]. 2015[acessado 2015 Out 23]; 20(8):2489-2498.

Chronic conditions, disability, and quality of life in older adults with multimorbidity in Spain. Eur J Intern Med 2015; 26(3):176-181.. Thus, the greater number of CNCDs in the questionnaire results in an increased percentage of multiple morbidities among the elderly¹⁹19 Van Den Bussche H, Koller D, Kolonko T, Hansen H, Wegscheider K, Glaeske G, von Leitner EC, Schäfer I, Schön G. Which chronic diseases and disease combinations are specific to multimorbidity in the elderly? Results of a claims data based cross-sectional study in Germany. BMC Public Health 2011; 11(1):1-9.. Conversely, including categories among the elderly with the highest number of diseases may decrease these percentages¹⁹19 Van Den Bussche H, Koller D, Kolonko T, Hansen H, Wegscheider K, Glaeske G, von Leitner EC, Schäfer I, Schön G. Which chronic diseases and disease combinations are specific to multimorbidity in the elderly? Results of a claims data based cross-sectional study in Germany. BMC Public Health 2011; 11(1):1-9..

It is important to note that most of the national studies analyzed factors associated with specific morbidity⁹9 Pimenta FB, Pinho L, Silveira MF, Botelho ACC. Fatores associados a doenças crônicas em idosos atendidos pela Estratégia de Saúde da Família. Cien Saude Colet [online]. 2015[acessado 2015 Out 23]; 20(8):2489-2498.

The female gender as a factor associated with diabetes (p = 0.047) was identified in a national study⁹9 Pimenta FB, Pinho L, Silveira MF, Botelho ACC. Fatores associados a doenças crônicas em idosos atendidos pela Estratégia de Saúde da Família. Cien Saude Colet [online]. 2015[acessado 2015 Out 23]; 20(8):2489-2498.

Age and gender differences in the relation of chronic diseases to activity of daily living (ADL) disability for elderly South Koreans: based on representative data. J Prev Med Public Health 2011; 44(1):32-40. found that the highest number of morbidities was associated with the female gender (p < 0.001)²⁵25 Garin N, Olaya B, Moneta MV, Miret M, Lobo A, Ayuso-Mateos JL, Haro JM.

http://www.ncbi.nlm.nih.gov/pmc/articles... .

This finding can be justified, among several factors, due to the strong gender component in the ageing of the population, with the highest percentage (55.5%) of the elderly women⁵5 Instituto Brasileiro de Geografia e Estatística (IBGE). Pesquisa Nacional de Saúde. Percepção do estado de saúde, estilos de vida e doenças crônicas. Rio de Janeiro: IBGE; 2014. [acessado 2015 Jul 10]. Disponível em: ftp://ftp.ibge.gov.br/PNS/2013/pns2013.pdf. This longevity, characterized as feminization of old age³⁵35 Araújo DD, Azevedo RS, Chianca TCM. Perfil demográfico da população idosa de Montes Claros, Minas Gerais e Brasil. Rev. enferm. Cent.-Oeste Min. 2011; 1(4):462-469. leads to greater vulnerability, such as greater susceptibility to chronic diseases³⁶36 Lima LCV, Bueno CMLB. Envelhecimento e gênero: a vulnerabilidade de idosas no Brasil. Saud Pesq 2009; 2(2):273-280.. Other aspects are related to women’s increased demand for health services. Higher percentages, when compared to males, were verified among elderly women of Guarapuava (PR) regarding the use of medical consultation services (p = 0.0029); clinical/laboratory test (p = 0.0208) and emergency care services (p = 0.0019)³⁷37 Pilger C, Menon MU, Mathias TAF. Utilização de serviços de saúde por idosos vivendo na comunidade. Revista da Escola de Enfermagem da USP 2013; 47(1):2013-2020.. In addition, females perceive health risks more easily due to the greater access to information³⁷37 Pilger C, Menon MU, Mathias TAF. Utilização de serviços de saúde por idosos vivendo na comunidade. Revista da Escola de Enfermagem da USP 2013; 47(1):2013-2020..

This result points to the need to consider gender as an important factor when searching for morbidities in the elderly and, thus, develop specific interventions for those that in literature have shown a greater propensity for adverse results²⁵25 Garin N, Olaya B, Moneta MV, Miret M, Lobo A, Ayuso-Mateos JL, Haro JM.

The lack of association between old age and increased number of diseases in this study does not corroborate with a national study in Teófilo Otoni (MG)⁹9 Pimenta FB, Pinho L, Silveira MF, Botelho ACC. Fatores associados a doenças crônicas em idosos atendidos pela Estratégia de Saúde da Família. Cien Saude Colet [online]. 2015[acessado 2015 Out 23]; 20(8):2489-2498.

Doenças crônicas não transmissíveis e fatores sociodemográficos associados a sintomas de depressão em idosos. J Bras Psiquiatr 2017; 66(1):45-51. and an international study in Germany¹⁹19 Van Den Bussche H, Koller D, Kolonko T, Hansen H, Wegscheider K, Glaeske G, von Leitner EC, Schäfer I, Schön G. Which chronic diseases and disease combinations are specific to multimorbidity in the elderly? Results of a claims data based cross-sectional study in Germany. BMC Public Health 2011; 11(1):1-9.^,2323 Schäfer I, Hansen H, Schon G, Höfels S, Altiner A, Dahlhaus A. et al. The influence of age, gender and socioeconomic status on multimorbidity patterns in primary care. First results from the Multicare Cohort Study. BMC Health Serv Res 2012; 12(1):1-15.. Some theories such as morbidity compression report a possible extension of the development of CNCDs to increasingly advanced ages³⁸38 Fries JF, Bruce B, Chakravarty E. Compression of morbidity 1980-2011: a focused review of paradigms and progress. J Aging Res 2011; 2011:261702.; and that related to increased morbidity proposes a reduced lethality of these diseases and, therefore, older and more long-lived individuals have a greater number of morbidities³⁹39 Kramer M. The rising pandemic of mental disorders and associated chronic diseases and disabilities. Acta Psychiatr Scand 1980; 62(S285):382-397.. Most of the elderly of this research, because they are not those of more advanced age can fit in this setting and for that reason do not show association between the variables.

Multiple chronic diseases are a frequent feature in old age⁴⁰40 Veras, RP. Prevenção de doenças em idosos: os equívocos dos atuais modelos. Cad Saude Publica 2012; 28(10):1834-1840. and this may be related to worse functional capacity¹⁸18 Rizzuto D, Melis RJF, Angleman S, Qiu C, Marengoni A. Effect of Chronic Diseases and Multimorbidity on Survival and Functioning in Elderly Adults. J Am Geriatr Soc 2017; 65(5):1056-1060.^,2525 Garin N, Olaya B, Moneta MV, Miret M, Lobo A, Ayuso-Mateos JL, Haro JM. Impact of multimorbidity on disability and quality of life in the Spanish older population. PLoS One [online]. 2014 Nov [acessado 2015 Ago 22]; 9(11):1-12. Disponível em: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4222819/pdf/pone.0111498.pdf
http://www.ncbi.nlm.nih.gov/pmc/articles... . This is corroborated by the high share of elderly individuals who self-reported two or more morbidities in this study and the association with functional limitations. However, according to scientific literature, the aspects that characterize the relationship between diseases and functional disability are still complex¹⁸18 Rizzuto D, Melis RJF, Angleman S, Qiu C, Marengoni A. Effect of Chronic Diseases and Multimorbidity on Survival and Functioning in Elderly Adults. J Am Geriatr Soc 2017; 65(5):1056-1060..

A research conducted with elderly enrolled in the Family Health Strategy in Teófilo Otoni (MG) did not identify an association between the presence of at least one disease and functional dependence in activities of daily life (ADL); on the other hand, when analyzed in isolation, diabetes remained associated with ADL dependence (p = 0.016)⁹9 Pimenta FB, Pinho L, Silveira MF, Botelho ACC. Fatores associados a doenças crônicas em idosos atendidos pela Estratégia de Saúde da Família. Cien Saude Colet [online]. 2015[acessado 2015 Out 23]; 20(8):2489-2498.

http://www.scielosp.org/pdf/csc/v20n8/14... . In the municipality of Japi (RN), elderly with hypertension (p = 0.001) and SAH and diabetes (p = 0.031) were associated with functional limitations for BADL. The relationship between IADL and increased morbidity was not identified and differed from this study³³33 Santos Júnior EB, Oliveira LPAB, Silva RAR. Doenças crônicas não transmissíveis e a capacidade funcional de idosos. Rev Pesqui Cuid Fundam (online) 2014; 6(2):516-524.. In another study with elderly women in Jequié-BA, SAH morbidity was associated with moderate/severe dependence for the IADL (p = 0.01)³²32 Virtuoso Júnior JS, Guerra RO. Incapacidade funcional em mulheres idosas de baixa renda. Cien Saude Colet 2011; 16(5):2541-2548..

The elimination of diseases can confer greater disability-free life expectancy²¹21 Campolina AG, Adami F, Santos JLF, Lebrão ML. A transição de saúde e as mudanças na expectativa de vida saudável da população idosa: possíveis impactos da prevenção de doenças crônicas. Cad Saude Publica 2013; 29(6):1217-1229.. On the other hand, it is believed that incapacitating processes can be a contributing factor, exacerbating comorbidity⁴¹41 Fried LP, Ferrucci L, Darer J, Williamson JD, Anderson G. Untangling the concepts of disability, frailty, and comorbidity: implications for improved targenting and care. J Gerontol A Biol Sci Med Sci 2004; 59(3):255-263. or configuring conditions for the development of diseases. In this perspective, it is relevant to adopt a model that monitors and stabilizes health conditions and problems and prioritizes maintenance of the functional capacity of the elderly⁴⁰40 Veras, RP. Prevenção de doenças em idosos: os equívocos dos atuais modelos. Cad Saude Publica 2012; 28(10):1834-1840..

A population-based research in Florianópolis (SC) found that people with one or more chronic diseases had a higher prevalence of depression⁴²42 Boing AF, Melo GR, Boing AC, Moretti-Pires RO, Peres KG, Peres MA. Associação entre depressão e doenças crônicas: um estudo populacional. Rev Saude Publica 2012; 46(4):617-623., corroborating this research. Likewise, a study carried out in Porto Alegre (RS) found an association between the elderly who reported coronary disease, stroke, heart failure and indicative of depression¹⁷17 Silva AR, Snaolin V, Nogueira EL, Loureiro F, Engroff P, Gomes I. Doenças crônicas não transmissíveis e fatores sociodemográficos associados a sintomas de depressão em idosos. J Bras Psiquiatr 2017; 66(1):45-51.. Hormonal and physiological changes in the body may be associated with depression and thus the development of chronic diseases. On the other hand, people with diseases may show limitations in performing daily activities and those related to social functions, aspects that are likely to culminate in mood disorders and depression⁴²42 Boing AF, Melo GR, Boing AC, Moretti-Pires RO, Peres KG, Peres MA. Associação entre depressão e doenças crônicas: um estudo populacional. Rev Saude Publica 2012; 46(4):617-623..

In view of the above, understanding the factors associated with morbidities in the elderly results in a better basis for the development of strategies for health promotion and disease prevention⁹9 Pimenta FB, Pinho L, Silveira MF, Botelho ACC. Fatores associados a doenças crônicas em idosos atendidos pela Estratégia de Saúde da Família. Cien Saude Colet [online]. 2015[acessado 2015 Out 23]; 20(8):2489-2498. Disponível em: http://www.scielosp.org/pdf/csc/v20n8/1413-8123-csc-20-08-2489.pdf
http://www.scielosp.org/pdf/csc/v20n8/14... , especially for the most vulnerable groups, such as the elderly, and thus improve health indicators⁹9 Pimenta FB, Pinho L, Silveira MF, Botelho ACC. Fatores associados a doenças crônicas em idosos atendidos pela Estratégia de Saúde da Família. Cien Saude Colet [online]. 2015[acessado 2015 Out 23]; 20(8):2489-2498.

http://www.scielosp.org/pdf/csc/v20n8/14... .

Limitations of this study are the research contour that does not allow establishing causal relations and the use of a questionnaire that may underestimate or overestimate some information found.

The data analyzed allow us to conclude that most of the elderly mentioned two or more diseases. The variables associated with the greatest number of morbidities were female gender, functional disability and indicative of depression.

Thus, the results found in this research configure the need to implement strategic actions directed to the monitoring and control of factors related to the presence of morbidities among the elderly. It is important to highlight that the identification and early diagnosis of morbidities result in the possibility of postponing possible complications and provide inputs for the local planning of health actions. The adoption of a model based on maintaining the functionality of the elderly can contribute in this aspect.
