INSTRUCTION, SOCIAL ECONOMIC STATUS AND EVALUATION OF SOME DIMENSIONS OF OCTOGENARIANS’ QUALITY OF LIFE

Objectives: To describe the profile of a sample of octogenarians (n=80) attended at the municipal health network of a city in the interior of São Paulo, Brazil; evaluate their perception regarding quality of life dimensions (QoL); identify correlations between socio economic status, education level and QoL. It is an exploratory descriptive study with a quantitative analysis of data. The results revealed that this population is predominantly female, widowed, illiterate, sedentary and poor, who need health services and leisure opportunities, and whose main support is religion. The socio economic status did not interfere in the QoL perception, though, higher education and participation in physical activities result in higher satisfaction.


INTRODUCTION
The World Health Organization estimates a 223% increase, between 1970 and 2025, in the number of people aged sixty or more (1) .Considering that older people do not comprise a homogeneous group, the diversity among individuals tends to increase.From this perspective, the concern with the development of actions that share values, despite the differences, involves an inclusive, flexible and dynamic signification that values people (2) .This process should support the optimization of knowledge and talents that encourage under-skilled people, satisfying their individual needs, so that they all feel welcomed, understood and respected regarding their different forms of being, learning and living (3,4) .
We are currently undergoing a demographic revolution, in which adults aged over 80 comprise the group with the (proportionally) highest growth in the world.
Today, the total number of octogenarians is approximately sixty-nine million; that is, 1% of the planet population, and 3% of developed countries' population (1) .In this context, governments, international organizations and civil society are called upon to promote health in its broadest perspective, surpassing the simplistic remediation view, and assure access to medical appointments, hospitalizations and medications (5) .Healthy aging should have a broader character.It should be recognized that health care and physical integrality are as important as an active participation in social, economic, cultural, spiritual and civil relationships that aim at elders' autonomy and independence.These activities should take place through a continuous process of education, growth, updating and personal fulfillment; and should include elders as effective members in the construction of society.
Broad, well founded knowledge about aging should be incorporated in curricula and training programs, so that students and workers from the social, health, recreation, urban planning and architecture areas work in collaboration and have the conditions needed to perform functions in agreement with the new demographic demands (1) .
In this perspective, public policies are challenged to open new horizons to the elderly age group, which is expected to reach 1.2 billion people in 2025 (1) .There is an urgent need for circumstances favorable to increasing situations of sharing, living together, as well as the possibilities of choice.
Indispensable adjustments to accessibility are mandatory as well.The integration between preservation and improvement in every community's wellbeing should be the focus of reflections, questionings, discussions and action plans in every dimension, so that aging can be a positive experience followed by infinite possibilities, resources and opportunities.Otherwise, we reach a merely quantitative advantage, adding years to lives without a qualitative concern to also add "life" to the years (6) .
Quality of life depends on several determining factors that derive from a history of interpersonal and environmental interactions in a continuous interplay of past and present external and internal influences (7) .
Bronfenbrenner's biologic approach appoints that a developing person's characteristics are strongly entwined with the social tissue.According to this systemic conception, the proposals will only make sense if the exchange processes that take place in as well as among the systems comprised by individuals, their caregivers, families and other contexts are taken into consideration (8)   .
Different from what happens in international literature, there are still few studies in our environment that specifically address elderly's quality of life.The lack of information regarding their perceptions, objectives, expectations, concerns and main difficulties need further investigation so as to better understand the tracks we must follow in terms of public policies and implementing services that meet the true needs and expectations of old age (9) .Therefore, we elected people aged 80 or more as the target population of our study, which aimed to: (a) describe their socioeconomic profile; (b) assess their perception regarding quality of life dimensions; and (c) identify correlations between their socioeconomic status, education level and total score obtained on the Alzheimer's quality of life scale (QOL-AD) (10) .At this moment, it should be clarified that we adopted the following quality of life dimensions to be investigated: physical health, eagerness, mood, housing, memory, family, marriage, friends, the overall you, ability to accomplish tasks, ability to carry out leisure activities, money, and life in general*.

METHODS
We performed an exploratory, descriptive study, with a quantitative approach.Data were  (11) .
Study subjects were 80 elderly people, users of the municipal health system in 2006, who met the inclusion criterion: being at least eighty years old.
The eligible participants were selected through a draw.
The first 80 subjects who agreed to participate comprised the study sample.
Data collection instruments were: The following scores were used: 1 for "bad"; 2 for "regular"; 3 for "good"; and 4 for "excellent".
The overall minimum score was 13 and the maximum 52.This instrument was chosen since it was elaborated for elderly with cognitive alterations and probable Alzheimer's Disease, but also for their caregivers, who do not necessarily present any health problems nor are aged over 60.Therefore, it is appropriate for any person.Moreover, since the average prevalence of Alzheimer's Disease in the world population is 16.22% among people aged between 80 and 84 years, reaching 54.83% for individuals over 95 (13) , we sought an instrument that would not exclude any person who met the research inclusion criteria, so that the results would show an overall profile of octogenarians.
After being approved by the Institutional Review Board at Sao Carlos Federal University, elderly who met the inclusion criteria, along with their lawfully responsible caregivers, were informed about the research and its objectives.Those who agreed to participate provided written consent and answered the instruments mentioned in the previous paragraph.
A single meeting with each participant was enough to collect and record the data.
The collected data were inserted in a database, using the Statistical Program for Social Sciences (SPSS-PC) for Windows, version 10.0, for statistical calculations and analyses.

RESULTS
Of all the participants (n=80), 58 were women As to sports activities, only women (1.3%) reported being a health club member, 21 (26.3%)went walking at least once a week, and most (n=58; 72.5%) did not do any physical activity at all.
In terms of the total scores obtained on the QOL-AD (10) , on a scale from 13 to 52 possible points, the lowest score was 19 and the highest was 48 (Figure 1).The evaluation frequencies participants reported about their quality of life dimensions are shown in Table 1.

Table 1 -Octogenarians' self-perception about quality of life dimensions
When octogenarians' information regarding the socioeconomic status is crossed with education level and total QOL-AD (10) score, there is no statistically significant correlation regarding education level and quality of life.However, it can be stated that there is a tendency towards higher scores among people with higher education levels (Figure 2).Participants who were used to walking were more fulfilled (m=38.2381,sd=5.27)compared to sedentary participants (m=32.9138,sd=6.2836),t(77)=3.463,p<0.001 (Figure 3).It appears that the average monthly income is not affected by subjects' quality of life.(Figure 4).Compl.elementary/incompl.primary ed.

FINAL CONSIDERATIONS
With health advancements, the tendency that people will live longer is incontestable.Therefore, it should be seen to that this track be pursued in the (a) characterization form and semistructured interview script: elaborated by the researcher to collect personal information and data about social living, recent life events, family composition, hobbies and physical activities;(b) Brazil Criterion Questionnaire(12)  : a scale that divides the population into seven social classes (A1, A2, B1, B2, C, D, and E) by means of an evaluation of the family purchase power, based on the number of durable consumer goods, instruction level of family head and some other factors, such as having a house maid.People with the highest purchase power were categorized as "A1", and those with lowest as "E";(c) The quality of life with Alzheimer's Disease assessment scale (QOL-AD)(10)   : a translated and crossculturally adjusted instrument validated for Brazil to assess the quality of life of caregivers and elderly with Alzheimer's.The thirteen scale aspects evaluated by the participant are: physical health, eagerness, mood, housing, memory, family, marriage, friend, the overall you, ability to accomplish tasks, ability to carry out leisure activities, money, and life in general.
