The World Health Organization conceptualizes an individual's aging as "a physiological process that begins with conception and causes changes, characteristic of the species, throughout the entire life cycle", in addition to considering elderly, those aged 60 years or older in developing countries, and 65 years or older in developed countries(1).
In view of this, some concepts for evaluating aging are fundamental, among them frailty and functional incapacity. Frailty is considered an inevitable consequence of aging, which is related to the different processes of non transmittable chronic diseases, thus characterizing a multidimensional syndrome that increases the elderly person's vulnerability, resulting in the reduction of physiological reserves and increase in functional decline associated with multiple physical changes(2-6) .
There are two groups of international investigations that have developed the research proposal on frailty, one of them developed in the United States of America, which points our the numerous markers that have been proposed for physical frailty. These include measurement of mobility and incapacity, and the phenotype operationalized by five indicators, among them: Weight loss, exhaustion, reduced grip force of the dominant hand; low level of physical activity, slow down measured walking speed indicated in seconds(7).
The research Group in Canada, Canadian Initiative on Frailty and Aging (CIF-A), acting in collaboration with European, countries, Israel and Japan in 2002, conducted researches establishing the following domains: histories, concepts and definitions; biologic bases; social bases; prevalence; natural history and risk factors; impact; identification; prevention and therapeutic conduct; environment and technology(8,9).
Another concept to be evaluated in the elderly is functional capacity, which may be defined as the physical and mental skills necessary for living an independent and autonomous life in order to develop daily life activities ranging from the basic through to the more complex type , without requiring help, thus providing better quality of life (10-13). When this condition is not developed, then functional incapacity arises.
Considering that when the increase in longevity is associated with frailty and functional incapacity in the elderly, they are more exposed to risks, thus one understands the need to investigate the subject, so that health actions may be planned, and offer the frail elderly a space to live under better conditions of life.
Based on the foregoing, the aims of this study were to characterize the sociodemographic profile of the elderly, verify the levels of frailty, according to gender, functional independence and instrumental daily life activities and correlate the dimensions of the Functional Independence Measure (FIM) and Instrumental Activities of Daily Living (IADL) with age, schooling, frailty and self-reported morbidities.
This is a research of an observational, cross-sectional nature, conducted with elderly persons, resident in the municipality of Ribeirão Preto - São Paulo, which has 539 sectors, and the Bonfim Paulista Sector with 11, totaling 650 sectors used by the IBGE to determine the censor sectors of the city.
Participants in the study were elderly persons residing in the municipality of Ribeirão Preto-SP, who were 60 years of age or older, of both genders.
The sample was obtained by two stage conglomerate sampling; in the first stage the censor sector was considered the sampling unit, and in the second stage, the individual of over 60 years of age. Thus, the decision was to obtain a sample of 240 elderly persons , which guaranteed a maximum error of 6.3% with 95% of probability. To arrive at a sample of 240, the plan was to draw 20 from the 650 existent censor sectors by lottery.
In the second stage, going through the streets on the basis of a random start, homes were visited until 12 elderly persons were found, who met the criteria for inclusion in the sample.
Data were collected between November 2010 and February 2011, and the team of interviewers consisted of a coordinator and two researcher teams, composed of post- and undergraduate students who had been previously trained. Duration of the interview was a mean of 40 minutes, with use of the following questionnaires:
For information on the sociodemographic profile of the elderly, the following variables were selected: gender, age, marital status, family income, scholarity, and family arrangement.
Frailty was measured with the Edmonton Frail Scale (EFS) validated for the Portuguese language, and was composed of nine domains, distributed into 11 items with scores from 0 to 17 points; categorizing the elderly into no frailty, apparently vulnerable, slight frailty, moderate frailty, and severe frailty. The higher the score, the higher was the level of frailty(14).
In the functional independence evaluation, the questionnaires of the Functional Independence Measure (FIM) and Lawton and Brody Scale were used. A FIM was validated for the Portuguese language; evaluating the performance in carrying out 18 tasks; each of these activities received a score from 0 (complete dependence) to 7 (complete independence); the minimum score of 18 points was equivalent to complete dependence, 19-60 points maximum/moderate dependence, 61-103 points minimum dependence and supervision, and 104-126 points changed or complete independence(15).
The Lawton and Brody Scale, which evaluates the Instrumental Activities of Daily Living (IADL) was adapted to the Brazilian context; with a minimum score of 5 points for the highest level of dependence, to 21 which corresponds to complete independence (16).
For data analysis an electronic spreadsheet was constructed in the software program EXCEL®, in which the data were organized in double digitization and validated by comparison of the digitizations. After validation, the spreadsheet was imported to the SPSS® 11.5 application, in which the statistical analyses were performed.
For analyses of the quantitative variables, the central tendency measures (mean, median) and dispersion (standard deviation) were used; for the categorical variables, the comparison of means test (Student's-t Test) and Pearson's correlation test were used, at a level of significance of 0.05.
The research project was approved by the Research Ethics Committee of the School of Nursing, Ribeirão Preto-USP (Process No. 1169/2010); in accordance with the National Health Council Resolution No.196/96 , which determines the guidelines and regulatory rules for research involving human beings.
The Term of Free and Informed Consent was signed by the elderly who participated in the study.
Of the 240 elderly persons interviewed, the majority were women, 25% were in the 80 years or over age group, with a mean age of 73.5 years and age-range from 60 to 94 years. As regards marital status, the majority were married (57.5%) and 48.8% had from 1 to 4 years of schooling. With respect to home arrangement, 29.8% lived with their spouse (Table 1).
When verifying the prevalence of frailty among the elderly, according to the EFS of the CIF-A(14), 36.3% did not present frailty; 24.6% were apparently vulnerable; and 39.1% had different levels of frailty, with 18.3% presenting mild frailty; 11.3% moderate frailty and 9.6% severe frailty. In addition it was found that elderly women presented higher levels of slight frailty (70.5%), moderate (66.7%) and severe (65.2%), according to the data shown in Table 2.
For functional capacity evaluation using FIM and the Lawton and Brody Scale (IADL), it must be pointed out that the frailty stages (mild, moderate and severe) were grouped into a category, namely frailty.
According to the results obtained by means of the FIM, it was observed that among the elderly who presented frailty, 3.2% were completely dependent; 5.3% presented maximum/moderate dependence and 29.8% minimum dependence/supervision. Among the elderly that presented no frailty, 98.9% were considered changed/completely independent, according to the data shown in Table 3.
When verifying the levels of frailty and IADL, 81.9% of the frail elderly presented partial dependence; and 64.4% of those who did not present frailty, were considered independent (Table 4).
It was observed that the lowest scores for Overall FIM and IADL showed negative coefficients of correlation; that is to say, the higher the age, frailty score and number of morbidities, the lower would be the overall FIM and IADL scores would be (p<0.01), according to the data shown in Table 5.
It was observed that there was a predominance of women and of the age group of 80 years or older, data similar to those of different international researches(3) and in Brazil(17-19).
At the beginning of the twentieth century, both children and youngsters, particularly women, did not have access to basic education, because of the formation of heterogeneous classes as regards age and gender, since they had to work on the land and care for the home.(20).
At present, in Brazil there are few studies about the frailty; in many cases due to the absence of appropriate tools and professionals qualified to identify the frail elderly person.
Aging with frailty is characterized by vulnerability and low capacity to bear stress factors, resulting in high susceptibility and greater degree of frailty, probability of becoming ill, and consequently an elevated number of hospitalizations that lead to greater dependence (21,22).
The research conducted used the EFS instrument with the aim of analyzing elderly persons' access to the health services offered by the Family Health Strategy in Embu das Artes -SP and the relationship between functional capacity and frailty in 128 elderly persons aged 60 years and over, and found that 30.1% of the elderly were frail(19).
Studies using the phenotype of frailty(7) identified 20% of frail and 46.7% pre-frail elderly persons, concluding that the frail elderly presented greater incapacity to perform routine activities and prevalence of the fear of falling(23).
Frailty is related to the female gender rather than the male, as can be observed in other researches in Peru(3) and Brazil(14). In a North American study, the authors identified a prevalence of 6.9% frailty in the elderly, with the majority being women (68.5%)(7).
The Pan American Health Organization estimates that 10% of the world population suffer from and have deficiencies, in addition to the fact that half of these persons present physical and/or functional difficulties(24).
In research conducted in the United States of America, the authors identified 59.7% of frail elderly persons with difficulty in performing the IADL and 27% in basic daily life activities, a result showing higher values than the data found in this research with regard to IADL. The researchers suggested that the onset of the frailty, it affects the more complex activities and a lower proportion of the simpler routine activities(7).
Moreover, it should be pointed out that women presented two times higher dependence when compared with men (25-26).
An international research with the aim of associating frailty with the incidence of functional capacity, reported that 4.3% of frail and 45.7% of pre-frail elderly were found in a sample of 1645 elderly persons in a community in a period of 10 years. The authors concluded that the frailty leads to impairment of elderly persons' ability to perform routine activities, making them dependent(6).
In a study with elderly persons resident in Peru, the authors described the frequency of the frailty in 246 elderly persons aged 60 years and over; reporting 7.7% with frailty and 64.6% pre-frail persons. They concluded that there was significant association between frailty and increase in age, which is greater in the female gender(3).
Among the elderly researched, the predominance of frail elderly was evident, and the majority were women, with a higher level of dependence shown by the FIM and IADL. In addition it was observed that the higher the levels of frailty, age and number of morbidities, the higher would be the level of dependence of the elderly.
At present, there is no consensus about the definition of frailty, which makes it difficulty to identify frail persons, however, it is known that the impact on the elderly person's life affects his/her quality of life, functional independence and autonomy itself.
At present, to evaluate and identify the frailty and functional incapacity in an elderly person is a problem for health professionals who work in the implementation of specific programs with the purpose of minimizing the effects of frailty and its consequences.
