METHOD: a cross-sectional study with 124 older people developed through home interviews. Functionality was assessed by Basic Activities of Daily Living (Barthel) and Instrumental Activities of Daily Living (Lawton and Brody); the main functional systems were assessed using the Mini-Mental State Exam, by the Timed Up and Go test, by the Geriatric Depression Scale (15 items), and questionnaire with sociodemographic variables. Bivariate and multivariate analyses were applied (Poisson Regression). RESULTS: 46% of the older adults showed moderate/severe/total dependence for basic activities and instrumental activities had a median of 12. In the multivariate analysis, there was an association between moderate/severe/total dependence on basic activities with cognitive decline (p=0.021) and bedridden/wheelchair users (p=0.014). Regarding the dependence on instrumental activities, there was an association with age ≥80 years (p=0.006), single/divorced marital status (p=0.013), cognitive decline (p=0.001), bedridden/wheelchair (p=0.020), and Timed Up and Go ≥20 seconds (p=0.048). CONCLUSION: the decline in cognitive and mobility was associated with poor functionality in basic and instrumental activities. The findings highlight the need to monitor Home Care for these individuals and serve as guidelines for health actions. Home Care (HC) has strategic potential given the scenario of fast population aging and the increase in chronic diseases that impact the functionality of individuals. In the Brazilian Health System (Portuguese: Sistema Único de Saúde, SUS), HC is organized into three modalities: Home Care type 1 (HC1), which is intended for users who require care with less frequency and complexity, being the responsibility of Primary Health Care (PHC); Home Care type 2 (HC2) and Home Care type 3 (HC3), which comprise the Melhor em Casa (Best at Home) program, being the responsibility of specialized services called Home Care Service (HCS) (Portuguese: Serviço de Atenção Domiciliar, SAD) (1) . HC1 is still insufficiently designed as to the systematization of the care provided, besides being scarcely addressed in published literature, when compared to HC2 and HC3. However, HC1 plays an important role in preventing worsening and health complications of individuals who find it hard to get to the health care service (1) . Although it is not directed only to the older adult, it is observed, in practice, that most users are over 60 years old, mostly in places with an older population. The older adults inserted in HC1 have some health disability and, often, limitations in their functional abilities. In this sense, the assessment of global functionality and associated factors is essential for identifying changes, implementing interventions, and establishing personalized therapeutic goals (2) . Global functionality is a comprehensive concept that encompasses the individual's ability to manage his/ her life and take self-care. It is the foundation of the health concept for the older adult and is anchored to the main functional systems of cognition, communication, mood, and mobility (2) . Studies conducted in Brazil, the United States, and England, with the older population in general, identified as factors associated with the decline in functional capacity (3) (4) (5) : illiteracy, older age (over 70 years old), having chronic diseases, cognitive decline, and not having social support, thus showing a complex network of multidimensional factors related to functionality. Gerontological nursing in the community can take action on several fronts, such as the provision of psychological, nutritional, and physical support for the older adult, being able to dedicate especially to actions of global functionality and activities of daily living (6) (7) (8) . In this sense, an intervention study conducted in New Zealand by nurses specialized in gerontology assessed the global functionality of the older population in the community using the Barthel index and the instrumental activities scale by Lawton and Brody. The authors identified a statistically significant increase for the intervention compared to the control group (p=0.03) concerning physical therapy as a form of rehabilitation (9) . In this perspective, the global functionality must be related to the associated factors of older people monitored by HC1, as this knowledge may enable the planning and implementation of specific gerontological nursing interventions that contribute to prevent injuries, postpone, or rehabilitate detected disabilities, besides subsidizing care management. Further, the assessment of global functionality may be used to obtain health indicators and outline care plans for the older adults followed by HC1. HC1 is near to the individuals monitored because it is the PHC's responsibility since it keeps the bond, the integrality, and the continuity of care to its users, which allows for early intervention and monitoring of health conditions (10) . However, there is still much to be explored, especially regarding gerontological nursing and its systematization. It is necessary to expand knowledge and technologies in the pace of demographic and epidemiological transition, which requires services and health care teams prepared to serve the fast-growing older population, since there may be a significant percentage of older people dependent on care and consequently, HC, especially provided by SUS. Given the above, the study aimed to analyze the association of global functionality with the main functional systems and the socio-demographic variables of older people followed by HC in PHC. This study contributes to the discussion on new health care practices, especially those aimed at gerontological nursing and on health policies aimed at the care of the older adult linked to HC1. of the older population in the municipality (11) To calculate the sample size, we used the WinPepi program, version 11.65. Based on a study conducted in the same city (12) , considering a significance level of 5%, the statistical power of 80%, a proportion of greater functional dependence estimated at 40%, and a minimum prevalence ratio of 1.7 to estimate associated factors the instruments that assess functional capacity, the total of 112 older people was reached. However, it was chosen to include the entire older population linked to the HC1 of the three services and, applying the inclusion and exclusion criteria, it totaled 124 older people. The inclusion criteria were people aged ≥60 years old, followed by the HC1 of the CSD in the city of Porto Alegre. The exclusion criteria were older adults who were not reached after three attempts at telephone contact, on different times and days, and who were not at home in the attempt of a home visit; those unable to communicate verbally or through writing; or with a previous medical diagnosis of advanced dementia and institutionalized older adult. Such conditions were informed by the health care team based on the user's medical record, or by the caregiver at the telephone or home visit. Data collection was conducted through structured interviews, at the participants' homes, conducted by nurses and undergraduate nursing students, previously trained. At first, the identification of users followed by the HC1 of the CSD in the city of Porto Alegre was developed through the records that had the contact information provided by the health care team. For those individuals who met the inclusion criteria, telephone contact was made to schedule an interview at home and, if telephone contact was not possible, there would be an attempt to go to the home. In this first approach, the eligibility criteria were confirmed and, therefore, 101 older people were excluded. A questionnaire with the following sociodemographic data variables: age, biological sex, education, marital status, family income, living alone or with a companion, morbidities, and time of follow-up in HC1 was used. Also, the presence or absence of a caregiver was investigated, considering caregiver the person responsible for assisting or providing physical, emotional, and/or financial support, and may be an informal caregiver (family or unpaid friend) or formal caregiver (hired and paid to provide care) (13) . It should be noted that these data were self-reported. Brody scale, respectively. The Barthel Index, a version validated for use in Brazil (14) , assesses the functionality in ten Basic Activities of Daily Living (BADL), with the score varying from 0 to 100. Scores below 20 indicate total dependence; from 20 to 35 indicates severe dependence; from 40 to 55, moderate dependence; from 60 to 99, slight dependence, and 100 is considered independent (14) . drawing. The score of these questions ranges from 0 to 9 points, the higher the score, the better the communication. The questions that assessed communication were not included in the multivariate analysis because they also belonged to the cognition scale with a strong correlation between these variables. The reduced Geriatric Depression Scale (15 items), validated for use in Brazil, was used to assess mood (17) . The total score ranges from 0 to 15 points. Scores between 0 and 5 represent normal (absence of depressive symptoms), between 6 and 10 represent mild depressive www.eerp.usp.br/rlae 4 Rev Latino-Am. Enfermagem 2021;29:e3476. symptoms, and between 11 and 15 represent severe depressive symptoms (15, 17) . test was used to assess mobility (18) . This instrument was applied according to the recommendations of the authors of the original instrument. Thus, the older person was told to sit in an armchair and to get up after the order "go"; walk forward to an established mark on the floor, at his/her usual speed; then, turn back and walk until he/she could sit in the same chair (19) . The cutoff points for this instrument were based on the original study (<10 seconds; 10 to 19 seconds; 20 to 29 seconds; ≥30 seconds) (19) . However, considering that this study sample were individuals who, in general, have mobility limitations (inclusion criteria in HC1), it was decided to classify the TUG in two categories: good mobility (time less than 20 seconds) and alteration in mobility (time equal to or greater than 20 seconds). It is noteworthy that the instrument was not used as an exclusion criterion, it was only used to assess the mobility of individuals who were able to perform the test. Therefore, the TUG was not applied to bedridden and wheelchair users, who were thus classified in the mobility category. The data collected were inputted twice in an Excel ® worksheet and later transferred to SPSS 21.0. To assess the factors associated with global functionality, bivariate and multivariate Poisson Regression analyzes were applied, analyzed dichotomously, with the highest risk outcome being: "moderate/severe/total dependence" in BADL and score <12 for IADL. The criterion for including the variable in the multivariate model was that it should have a p<0.10 value in the bivariate analysis. The measure of effect used was the Prevalence Ratio (PR), together with the 95% confidence interval. The 5% level of significance was adopted (p<0.05). The study was approved by the Research Ethics Most were females (75.8%), with an average age of 82.8 years (± 9.2). Table 1 shows the sociodemographic characteristics and the follow-up time in the sample's HC1. It is worth mentioning that nearly half of the sample, 48 .4%, had been followed up by HC1 for more than three years. were severe, 49 (39.5%) were bedridden/wheelchair users and, of those who walked (n=75), more than half (64%) had TUG ≥20 seconds. (20) (21) (22) . As for age, more than half of the sample was 80 years old or over, older than the age group found in another study developed in low-income communities in the same municipality with older adults under HC (20) and similar to a cross-sectional study conducted in the United States with older people followed by HC (23) . There may be a chance that people in a less fortunate socioeconomic condition, associated with other factors such as chronic illnesses, clinical conditions, a propensity to fall, and limited ability to perform physical exercises, develop dependence for the performance of activities and need care at home earlier (24) (25) . About half of the sample (48.4%) had been followed up by HC1 for more than three years. The longer the followup time, the greater the bond between professional and user, which may encourage care to keep its functionality. Japanese and European studies highlight the growing need for HC with an emphasis on the quality of life of the older adult, suggesting that, to achieve this purpose, changes in functionality must happen, besides investing in actions aimed at social engagement, cognitive development, and mental health (25) (26) (27) . Still, a systematic review and metaanalysis study of prospective cohort studies highlight that the early assessment of frailty can effectively prevent frailty-induced disability in the older adult (6) . It should be observed that of the participants in the present study, 67 older people (54%) were independent or had slight dependence on BADLs, and 73 (58.9%) had a low level of dependence on IADLs, indicating the importance of early intervention by health professionals in the older population of HC1. Regarding the need to have a caregiver, to live with somebody, and about the number of morbidities, it was observed that more than half of the older adults had an informal caregiver, lived with somebody, and with a median of three morbidities. The need to have a caregiver with advancing age is an event that has been discussed in national and international studies (13, (28) (29) . More specifically, informal care is the main type of care for the older adult in many countries (30) , being understood as a fundamental pillar for guaranteeing and maintaining HC for the frail older adult (28, 31) . Thus, according to a systematic review that aimed to identify the preferences and needs on the organization of informal care in 44 studies from 17 different countries, demographic, financial, and cultural aspects of each circumstance must be considered, as these they may influence the preferences and needs of informal caregivers (28) . Therefore, the support network must be strengthened, especially HC1, to assist both the informal caregiver and the older adult with functional limitations at home (13, 29) . As for global functionality, more than a third of the sample showed slight dependence on BADLs and greater dependence on IADLs (with a low median). This characterization is expected for follow-up HC1 (2) , although the percentage of these data was not known for that specific population. In natural aging, the individual first have a decrease in the ability for performing complex activities, gradually increasing the need for family and social support in other tasks (4) . Until recently, these older people received care only in the health service, to which they often had to travel bearing transport costs, while others only accessed such services through emergencies. In this sense, HC1 contributes to promote access to health. Therefore, the interventions provided must be directed towards the prevention of health problems, treatment, palliation, and rehabilitation, considering the assessment of the socioeconomic context, individually (2) . Regarding the cognition functional system, the percentage of cognitive decline in studies that used MMSE was higher than that found in a cross-sectional study with older community members from seven Brazilian cities, in which 65.1% of the participants were younger than 75 years old, and only 24.8% had cognitive decline (32) . It was also greater than in an American cohort study with older people with an average baseline age of 90.3 ± 6.3 years, in which only 25% of these older people had cognitive decline (33) . These data highlight the specific limitations of older people who followed up by HC. Also, a South Korean study conducted with older people from the community informs that cognitive decline is a factor that may influence the frailty in older population (34) . A South African study with focus groups conducted with older residents in a community, from three areas (high, medium, and low income) describes that communication is necessary for the older adults to understand their health condition and have adherence to the care plan presented (35) . Thus, as for the communication Nevertheless, it is necessary to guide the older adult and their caregivers, who are sometimes also older adults, for the use of these technologies, especially robotics, which may qualify and improve the assistance provided. In this perspective, a Canadian study that proposed a remote assessment for older residents of the community during the COVID-19 pandemic indicates that, in cases where the older adult have difficulty using the technology, they can be assisted by someone else, such as a health professional or a caregiver (37) . Regarding the mood functional system, about half of the sample had mild or severe depressive symptoms, which indicated the need for active listening approaches, with a psychosocial focus for these individuals. This percentage of older people with depressive symptoms was higher than that found in other national studies with older people in the community who applied the same assessment tool (38) (39) . This finding may be related to the limitation to leave the house, which is a frequent concern of users of HC1. Depressive symptoms may result in indifference in performing activities of daily living (40) . Further, a cross-sectional Canadian study of individuals with work-related musculoskeletal disorders suggests that fatigue contributes to disability and that a significant decrease in fatigue can be achieved through psychosocial interventions that promote the individual's rehabilitation, thereby lessening the severity of depressive symptoms (41) . In this sense, health professionals must be attentive to these circumstances, promoting activities aimed at reducing depressive symptoms, without neglecting the natural aging process. Mobility was the functional system in which the sample had great limitations, as more than a third were bedridden/wheelchair users, and, of those who could walk, more than half had a time equal to or greater than 20 seconds in the TUG. Mobility problems, found in the present study, evidenced by the longer time for the performance of the TUG, work as a warning for preventive actions mainly because they increase the propensity for falls (18) . This change in mobility and its repercussions on social participation may be related to the depressive symptoms observed in almost half of the sample. Regarding the factors associated with global functionality, sociodemographic characteristics did not show a statistically significant association in the multivariate analysis with moderate/severe/total dependence on BADL, diverging from other national studies with older people, in general, that used the Katz Index (3) (4) . However, with a score of less than 12 in the IADL, a significant association was found in the age group equal to or older than 80 years (p=0.006) and the single/divorced marital status (p=0.013), showing that, with advancing age, the ability to perform more complex activities is lost. This finding is similar to a crosssectional study with 313 older people from Portugal, which showed aged people without much concern with self-care activities, as they feel that it is not worth living, thus presenting a greater functional dependence (42) . In the multivariate analysis, there was a significant association of a greater functional dependence in BADL and IADL with the cognition and mobility functional systems. This finding may be related to neurodegenerative diseases and their higher prevalence at older ages. Cognitive decline showed a similar association to other Brazilian studies with older people, in general, which used MMSE (3, 38) . A cross-sectional study developed in four places in Canada and Latin America with 1,071 participants living in the community (aged 64-75 years) highlights the need for interventions focused on the cognitive and physical performance of the older adult, to prevent disabilities (43) . (4, 43) . Regarding the change in mobility, being a bedridden/ wheelchair user was associated with greater dependence on BADL and IADL. The association found emphasizes the need for a personalized care plan aimed at the implications of altered or mobility problems in the performance of activities, aiming at rehabilitating and/or preventing complications, such as pressure injuries and immobility syndrome (2) (45) . In the multivariate analysis, the mood functional system did not show a significant association with greater dependence, diverging from other Brazilian studies with larger samples of older people in the community that employed the Lawton and Brody, Katz, and the reduced Geriatric Depression scales (46) (47) . However, we emphasize the importance of professionals to intervene early, enabling family members to be alert to depression symptoms and to communicate to the health care team, to minimize dependence on the performance of functional capacity and impact on morbidities in the older adult (46) . research studies suggest that more efforts are needed to implement and coordinate HC services and, also, to guarantee good practices, with a view to the quality of care and health conditions at a fair cost for users with disabilities, to promote well-succeeded aging (48) (49) . Thus, it is considered that, with the fast population aging and the consequent increase in demands on health care services for the older adult, especially for HC, it is necessary that nurses working in PHC improve knowledge directed to care in geriatrics and gerontology. In clinical practice, it is observed that a full geriatric evaluation, with a suitable anamnesis and approach of the main functional systems, evaluated in this study, associated with the elaboration of a care plan focused on this population, considering that continuing this care allows the delay of health problems and the subsequent increase in the quality of life of the older adults (50) . Moreover, it reduces costs for the healthcare system and the stigma associated with disability (50) . It should be noted that HC1 is present in care management, identifies needs early, strengthens bonds and the formal and informal support network, thus expanding access to health. This study presents as a limitation the cross-sectional design, not allowing causal inferences. In addition, the findings cannot be generalized, because of the specific characteristics of a given region and for not having included older people without communication skills and/ or with advanced dementia. New intervention studies are suggested to obtain more subsidies to assess the global functionality of older people monitored by HC1 as an outcome, to expand the discussion, to add well-being to longevity, and provide support to the older adults, family members, and/or caregivers.
