investigating the association between frailty syndrome and sociodemographic characteristics in long-lived individuals of a community.


a cross-sectional study with a proportional stratified sample consisting of 243 long-lived individuals. A structured instrument, scales and tests that comprise evaluating frailty were applied for data collection. Univariate and multivariate analyzes were performed by logistic regression (p<0.05) by Statistica 10(r) software and Odds Ratio (95% Confidence Interval) were calculated for the predictive models.


of the 243 long-lived individuals evaluated, 36 (14.8%) were frail, 55 (63.8%) were pre-frail and 52 (21.4%) were not frail. A predominance of females (n=161; 66.3%), widows/widowers (n=158; 65%), who lived with family members (n=144; 59.3%) and in a self-reported satisfactory financial situation (n=108; 44.5%) was observed. A significant association was found between the demographic variable of age (p=0.043) and frailty syndrome. The best predictor model for the syndrome included the variables: gender, age and household companion.


the variable of age contributed most to the fragilization process of long-lived individuals residing in the community. It is essential that gerontological nursing care contemplates early detection of this syndrome, considering age as being indicative of care needs.

Para a coleta de dados aplicaram-se instrumento estruturado, escalas e testes que compõem a avaliação da fragilidade física. Realizaram-se análises univariada e multivariada por regressão logística (p<0,05) pelo software Statistica 10(r) e para os modelos preditores foram calculadas Odds Ratio (Intervalo de Confiança de 95%).


dos 243 longevos avaliados, 36 (14,8%) eram frágeis, 155 (63,8%) pré-frágeis e 52 (21,4%) não frágeis. Houve predomínio do sexo feminino (n=161; 66,3%), viúvos (n=158; 65%), que residiam com familiares (n=144; 59,3%) e com situação financeira autorrelatada satisfatória (n=108; 44,5%). Identificou-se associação significativa entre a variável demográfica idade (p=0,043) e a síndrome da fragilidade física. O melhor modelo preditor da síndrome compreendeu as variáveis: sexo, idade e com quem mora.


a variável idade foi a que mais contribuiu para o processo de fragilização dos longevos que residem na comunidade. É essencial que o cuidado de enfermagem gerontológico contemple o rastreamento precoce da síndrome e considere a idade como um indicativo de necessidades de cuidados.

The increase in the number of elderly people (also called long-lived individuals or oldest old) at 80 years or more is a world-wide reality. A decrease in physical reserves and an increase in vulnerability to internal and external stressors is common in this population segment, culminating in the development of physical frailty1. Researchers define it as a medical syndrome with multiple causes and related factors, characterized by a decrease in the body's homeostatic reserve capacity and resistance to stressors, which result in cumulative declines in multiple physiological systems causing vulnerability and adverse clinical outcomes1-2.

In order to evaluate the syndrome, the frailty/fragility phenotype stands out, being composed of markers that include: slow gait, reduced hand grip strength, unintentional weight loss, self-reported exhaustion and low level of physical activity. Long-lived individuals who do not have any of the markers are considered as not frail, those with one or two markers are pre-frail, and three or more characterize frail aged adults2.

The frequency of physical frailty presents great variability, whether in homogeneous or distinct long-lived populations3. In younger aged adults (60-69 years), values between 6.9% and 9.3%2,4) are predominant, while the index is significantly higher for long-lived individuals (≥80 years), ranging from 16% to 26% (3.

High prevalence rates of the syndrome in the national context do not correspond to the number of publications found in Brazilian gerontology nursing literature or in general health5. This suggests the need for further studies investigating the predictive characteristics of the syndrome, since they provide valuable subsidies for care management. These studies especially focused on long-lived individuals cannot be disregarded, as they are high risk for frailty with a higher probability of changing from pre-frail to frail2, and which predisposes this age group to hospitalizations, falls and dependencies.

Among the factors that determine frailty development, some sociodemographic factors stand out even though they are often ignored by the healthcare team providing care, and they should be systematically investigated in evaluating longed-lived older adults. In developing countries, higher values of frailty in elderly6 have been identified. In investigations carried out in Mexico7 and Peru8, researchers have demonstrated frailty associated with sociodemographic variables, including female gender7 and age7-8.

Despite sociodemographic variables that are associated with frailty being known, we highlight a lack of national studies that investigate predictive models of frailty based on these characteristics of the population. In view of the above, the objective of the present study was to investigate the association between frailty syndrome and sociodemographic characteristics of long-lived individuals in a community.


A cross-sectional study developed with long-lived individuals (≥80 years) living in a community of households in an area covered by three Basic Health Units (UBS) belonging to the Boa Vista Sanitary District, in the city of Curitiba, Paraná, Brazil. As criteria the choice of these UBS9)1 was the representativeness of different social strata associated to the greater number of long-lived adults enrolled in the UBS. A proportional stratified sample was adopted, considering the number of long-lived individuals enrolled in each UBS, so that none of the UBS was over or underestimated. The sample calculation considered the population of long-lived individuals enrolled in the three UBS (N=503), an 80% (1-ß) beta value, a 5% significance level (α=0.05) and a 10% significant minimum difference between the proportions of long-lived individuals with frailty. The sample size was increased by 10% due to the possibilities of losses and refusals, which resulted in the final sample being 243 long-lived individuals.

The selection of the aged adults was randomly carried out through a draw based on the list of long-lived individuals registered at the UBSs generated by the city's electronic system. Home visits were made, and a new name was drawn in cases of refusal or absence (three attempts for each household).

Inclusion criteria were: a) being ≥80 years of age; b) being enrolled in one of the UBS participating in the study; c) scoring higher than the cutoff point in the Mini Mental State Examination (MMSE)10, which was 13 points for illiterates, 18 for having an average or low education level, and 26 points for having a high education level11.

The family caregiver was invited to participate in cases where long-lived individuals did not have cognitive conditions (n=36) to answer the research questions, and for which the following inclusion criteria were considered: a) being ≥18 years of age; b) being a family caregiver; c) living with the aged adult for at least three months. Long-lived individuals who were physically unable to perform the physical tests (n=15) or in chemotherapeutic treatment (n=1) were excluded.

Data collection was carried out from January 2013 to September 2015 by previously trained scientific initiation fellowship, master's and doctorate students. A pilot study with ten long-lived individuals was conducted for verification and adequacy of the instrument.

The structured questionnaire included sociodemographic variables of interest to the study adapted from the Brazilian Institute of Geography and Statistics12, and categorized according to statistical recommendation and/or studies that supported the methodology (11: gender (female, male); age (≥80 and <87, ≥87 and <93, ≥93 and <100 years); marital status (widower, married, single); education level (illiterate, low, average, high); household situation (living alone, living with family members, living with a partner); self-reported financial situation (unsatisfactory, average, satisfactory); individual monthly income (insufficient ≤1.0 minimum wage (MW), average >1.0 MW and ≤2.0 MW, satisfactory >2 MW) and monthly family income (insufficient ≤2.0 MW, average >2.0 and ≤5.0 MW, satisfactory >5 MW).

Physical frailty markers were evaluated according to the authors' proposal2) in the Cardiovascular Health Study (CHS), a prospective and observational reference study conducted in the United States with 5,317 community aged adults between 65 to 101 years of age.

Hand Grip Strength (HGS) was measured with a Jamar(r) hydraulic dynamometer according to the American Society of Hand Therapists13. The highest of three obtained measurements presented in kilograms (Kgf) was considered14, adjusted according to gender and body mass index2 (BMI=weight/height2), and values in the lowest fifth were considered frailty markers, as observed in Figure 1.

In order to evaluate the Gait Speed (GS) marker, the long-lived participants were instructed to walk a distance of six meters15 in a usual manner on a flat surface marked by two marks of four meters distance from one another. Only the intermediate four-meter course was considered to reduce the effects of acceleration and deceleration. Time was measured in seconds by a digital stopwatch and divided by the four-meter trajectory, thus resulting in a GS in meters/second, as according to an international study2).

The results were adjusted according to gender and height2, and then divided into two categories based on the median (50th percentile): men ≤166 cm and women ≤152 cm (below or equal to the median); and men > 166 cm and women > 152 cm (above the median). The cutoff points were set in the lower fifth2 for each category with the following values for men and women, respectively: below or equal to the median of ≥9.65 s and ≥13.0 seconds; and above the median of ≥7.97 s and ≥11.6 seconds. Values equal to or greater than the cutoff points on the walking test were considered as markers for the syndrome.

Unintentional weight loss was verified according to participants' self-report regarding the following questions: a) Have you lost weight in the last twelve months? b) If so, how many kilos? The caregiver was consulted if they did not remember their weight a year ago. Unintentional (without diet or exercise) weight loss reported as greater than or equal to 4.5 kg in the last twelve months was considered a marker for physical frailty2.

Fatigue/exhaustion was evaluated based on self-reporting for a question from the Depression Scale of the Center of Epidemiological Studies16: "Do you feel full of energy?" A visual scale was used to measure energy level using a ruler numbered from zero to ten, with zero being the minimum energy level and ten the maximum. Negative responses provided by long-lived individuals to the question associated with an energy value equal to or less than three points on the ruler were considered as a marker for the syndrome17.

The reduction in physical activity level was evaluated using the "Physical Activity Level Questionnaire for the Aged" - CuritibAtiva. The validated instrument18 contains twenty questions subdivided into: systematic practice of physical activities (n=7); heavy household or occupational tasks (n=7); and social and leisure activities (n=6). The questions refer to the frequency and duration of the activities performed in the last week, and the score is converted into the following classification: inactive (0-32); slightly active (33-82); moderately active (83-108); active (109-133); very active (≥134). Classifications compatible with the inactive and slightly active groups were considered as a marker for the syndrome.

The results were tabulated and analyzed in Statistica10(r) software. Descriptive statistics were obtained through distribution of absolute and relative frequency, mean, standard deviation, mode and median. The association between frailty and independent variables was analyzed by the chi-square test, with p<0.05. Two groups were analyzed (Cluster analysis) in the multivariate model using logistic regression, which lead to merging the pre-frail and not frail categories. The priority response for prediction was defined as the frail response, and the other category (not frail) was attributed as its complement in order to follow a model associated with a binomial distribution.

A complete predictive model was developed for frailty in which all variables of the study were included. Using the Forward Stepwise method, the sociodemographic variables were individually entered into multiple logistic regression analyzes, starting with those that showed a lower individual p-value for the complete model. The Likelihood Ratio Test (LRT) was implemented for selecting the models, and the quality of fit was assessed by Deviance analysis. The respective Odds Ratio (OR) and Confidence Interval (CI) of 95% were also calculated.

The study complied with national and international standards of research ethics involving human subjects, and was approved by the Research Ethics Committee in Human Beings of the institution under registration CEP/SD: 156.413.


For physical frailty, 36 (14.8%) of the long-lived individuals were classified as frail, 52 (21.4%) as not frail, and 155 (63.8%) as pre-frail. A predominance of females (n=161; 66.3%), in the age group ≥ 80 to <87 years (n=181; 74.5%), with a mean age of 84.4 (SD=3.8) was observed. The majority were widowed (n=158; 65%), with a low education level (n=137; 56.4%), and living with family members (n=144; 59.3%). Of the participants, 108 (44.5%) considered their financial situation satisfactory; however, most of the long-lived individuals (n=181; 74.5%) reported their individual monthly income as insufficient (receiving up to a minimum wage)2*. Regarding frail individuals (n=36; 14.8%), the majority were females (n=25; 69.4%), widowed (n=27; 75%), living with family members (n=28; 77.7%), with average financial situation (n=16; 44.4%) and individual and familiar monthly income classified as insufficient, in the same frequency (n=28; 77.8%). There was a significant association between age (p=0.0432) and frailty (Table 1).

Three predictive logistic models of frailty for long-lived individuals were carried out. The complete model (p=0.352) included the variables of gender, age, marital status, household situation, education level, financial situation, individual and family income. Model 1 (p=0.075) included gender, age and household situation. Model 2 (p=0.045) considered the variables age, household situation and individual income. No significant associations were found between the models (Table 2).

The complete model presented a higher predictive value (62.5%) and specificity (60.8%). Model 1 had better sensitivity (77.7%), lower predictive value (48.1%) and specificity (42.9%). Model 2 presented worse sensitivity (69.4%), with a predictive value of 57.2% and specificity of 55% (Table 3). The choice for the best prediction model of frail long-lived individuals considered the parsimony rule and a higher index of sensitivity. Thus, we opted for the choice of Model 1.

The condition of pre-frailty and frailty was significantly higher when compared to the Cardiovascular Health Study (CHS), which showed a prevalence of 46.6% of pre-frail older adults and 6.9% of frail older adults in a sample of 5,317 older/aged individuals, between 65 and 101 years old2. This result is due in part to the characteristic of the studied population, since they are older individuals aged 80 years or more.

Results close to the present study are presented in cross-sectional surveys with 1,327 Spanish older adults (≥65 years), who identified 19.1% frail adults among the older adults in the group aged ≥75 years19; and the Frailty in Older Brazilian People Network (FIBRA) carried out in seven Brazilian cities revealed 19.7% as frail and 57.2% as pre-frail20 among the 512 long-lived individual participants. The high number of frail and pre-frail participants identified in this study similar to those long-lived individuals in the aforementioned investigations19-20 supports the relevance of preventive or therapeutic intervention actions in the care of long-lived individuals, with the objective of delaying or avoiding hospitalizations, falls and dependence, which are typical situations and events that occur due to physical frailty.

Regarding the general characterization of the sample, the findings are similar to the results of national studies with long-lived individuals, which have indicated a greater number of women with a mean age of 84.4 years, widowed, with z low education level21-22, living with a partner and/or family members21 and receiving up to one minimum wage22. It is noticed that they are older women, with years marked only by the increase in life expectancy, who, nonetheless survive in undesirable physical and socioeconomic conditions, and for whom there is no specific care policy in force.

We observed that long-lived women were twice as frail as long-lived individuals, however, a significant association was found between the female gender and frailty. It can be inferred that this result is due to the quantitative study participants, which represent a local reality in the South of Brazil. This result differs from others found in the literature which demonstrate such an association2,19-20. Among the contributory factors are physiological characteristics, unfavorable psychological and social conditions, stressors that interfere in the health status and contribute to an increase of accumulated deficits.

Among octogenarians (in their 80's) and nonagenarians (90's), the frequency of the syndrome did not increase with age, which can be explained by the categorization of the age groups which caused stratification of the aged population. However, univariate analysis revealed a significant association between age and frailty, similar to international and national studies3-5.

The significant increase in frail older adults in advanced ages suggests progressive condition of the syndrome, which is determined by physiological factors that can justify this relationship. In the perspective of the model proposed by North American authors2, the aging process predisposes individuals to develop physical frailty, and it can be related to changes and the decline of multiple systems, resulting from physiological mechanisms and pathological conditions2 which may be reflected in accumulated damage to the health and functionality of the aged individual20.

An analysis of marital status pointed to a higher proportion of frail widowed older adults, as expected for the age range of the study population and the predominantly female composition of the sample. A similar result was identified in other investigations5,19. However, unlike the longitudinal study with 1887 younger Italian aged adults, no significant association between widowhood and physical frailty was identified23. We highlight that widowhood can contribute to social and family isolation, and therefore lead to developing self-care deficit due to lack of encouragement from a partner.

It is noteworthy that more than half of the frail individuals had 1 to 4 incomplete years of study; however, this variable was not associated with the syndrome, corroborating a national study with community aged adults5. Nevertheless, a study conducted with 1,933 Mexican older adults at 65 years of age or older identified a higher probability of the syndrome in the aged with lower education levels (OR=2.51)7.

Despite developing countries having higher rates of illiteracy and lower education levels, a significant association between education level and the syndrome is found in developed countries such as Spain19 and Japan4. In this sense, the educational level can be considered a protection factor, since it provides individuals with better access to information and services, as well as financial resources and employment opportunities.

The household situation variable had no significant association for the frail older adults, similar to a study developed with 203 aged people from Curitiba, whose objective was to investigate the association between frailty syndrome and sociodemographic and clinical characteristics of aged adult primary care users (24. This result differs from those of other studies that observed this relationship among older adults who lived with family members25 and those living alone2,4,7. Social bonds and the support experienced can influence the health maintenance, promoting adaptive behavior in stress situations.

Regarding the financial situation, no significant association between individual and family monthly income with the syndrome was found. However, some authors indicate that aged adults with unfavorable or insufficient income are more frail7-8. Socioeconomic conditions can trigger the physical frailty cycle in the aged as they hinder access to adequate food, health services, medicine and to practicing physical exercise, predisposing the individual to diseases and decreased functional capacity.

The predictive model of physical frailty chosen included variables that were associated with the syndrome: gender, age and household. Studies highlight advanced age and female gender as conditions strongly present in predictive models of frailty, both in the national5 and international context2,25.

The present study indicated greater chances of physical frailty in participants who lived with family members. This relationship was also observed (p=0.012)25) similarly to a multicentric cross-sectional study conducted with 1,126 aged Turkish people investigating characteristics, prevalence and associated factors related to this syndrome in older adults. Higher odds of developing the syndrome in participants residing with family members can be attributed to the condition of long-lived individual's presenting some type of dependency (physical, financial or psychological), which may contribute to or accelerate the frailty process.

The cross-sectional design was a limiting factor in evaluating cause and effect relationships. Moreover, the sampling is representative of a local community, and therefore the results cannot be extrapolated to other territories. We suggest that further longitudinal, cohort, and population studies that allow for observing physical frailty levels in long-lived individuals and a deeper exploration of the relationship between the syndrome and sociodemographic variables be carried out.

Based on these results, we suggested that health professionals consider sociodemographic variables for screening physical frailty, seeking early identification of the syndrome. Thus, nursing care performed in basic care units can be targeted to specific groups of older adults and/or families (women, with advanced age, living with their family members) as an attempt to delay the frailty process and avoiding its negative outcomes.


Regarding the investigated sociodemographic variables, we can conclude that age significantly contributed to the frailty process in long-lived individual users of basic health care (units). The results show the influence of the aging process on the syndrome's occurrence, and it supports biological characteristics of the physical frailty phenotype proposed by North American authors.
