INTRODUCTION

The increase in longevity and the change in the epidemiological profile have significantly enlarged the concept of health and the spectrum of indicators that are necessary to monitor it. Considering that people’s subjective assessment of their own health status is an important indicator of the disease’s impact on individual wellbeing,⁴4 . Barros MBA, Francisco PMSB, Lima MG, Cesar CLG. Social inequalities in health among elderly. Cad Saude Publica. 2011;27(Supl 2):s198-208. DOI:10.1590/S0102-311X2011001400008 this measure started to be used in population-based surveys, together with other self-report measures of: signs, such as falls and incontinence; symptoms, such as fatigue, sadness and anxiety; recall of clinical diagnoses made by doctors; and functional performance, indicated by the degree of the need of help to perform activities of daily living.

Self-reports on morbidities, signs and symptoms and functional capacity focus on individual clinical conditions and are in good agreement with medical records or clinical examinations.³⁰30 .

DOI:10.1016/S0033-3506(00)00323-1 Self-rated health implies questions and answers of an evaluative and comparative nature. It is a complex measure, influenced by the same elements that control reports on signs, symptoms, functional performance and medical diagnoses. The difference between these two types of measure is the fact that self-reports on signs and symptoms have a descriptive character, while self-rated health has a global, evaluative nature, indicated by answers that are characterized as a personal judgment, which is based on individual and social-normative criteria of priority access to the respondent.¹¹11 .

Studies on the relationships between health assessment by objective criteria and by subjective criteria are based on comparisons of healthy or successful aging measured by the two assessment criteria. The correlation between the health status measured by objective and subjective indicators tends to weaken as age advances.¹¹11 . Latham K, Peek CW. Self-rated health and morbidity onset among late midlife U.S. adults. J Gerontol B Psychol Sci Soc Sci. 2013;68(1):107-16. DOI:10.1093/geronb/gbs104 Among older adults, the incongruence reflected on low scores in objective health and high scores in self-rated health (or subjective health) may be explained by compensatory mechanisms of an affective nature, whose function is to protect the individual’s self-esteem, sense of self-efficacy and subjective wellbeing.²⁶26 .

A longitudinal study that included in its baseline individuals without illnesses and without disability has shown that morbidity, even when adjusted by sociodemographic variables, utilization of and access to health services and health risk factors is, over time, a predictor of self-rated health.¹¹11 . Latham K, Peek CW. Self-rated health and morbidity onset among late midlife U.S. adults. J Gerontol B Psychol Sci Soc Sci. 2013;68(1):107-16. DOI:10.1093/geronb/gbs104 The study has also reported that disability has a direct relationship to subjective health assessment. In relation to depression, a meta-analysis involving longitudinal and cross-sectional studies has found that the presence of chronic diseases and of a poor perceived health was associated with depression in older adults, and that self-rated health presented a higher association with depression than with self-reported chronic diseases.⁷7 .

DOI:10.1093/ageing/afp187

In Brazil, population-based studies have shown an association among self-rated health, morbidity and functional capacity in older adults,¹⁷17 . Nunes APN, Barreto SM, Gonçalves LG. Relações sociais e autopercepção da saúde: Projeto Envelhecimento e Saúde. Rev Bras Epidemiol. 2012;15(2):415-28. DOI:10.1590/S1415-790X2012000200019^,2525 .

DOI:10.1590/S1415-790X2012000100005 but the magnitude of this relationship, when variables like mental health and subjective wellbeing are included, has not been investigated yet.

The aim of the present study was to analyze the association between negative self-rated health and health indicators, wellbeing and sociodemographic variables in older adults.

METHODS

Data from the population-based Campinas Health Survey (ISACamp 2008/2009)^aa Universidade Estadual de Campinas, Faculdade de Ciências Médicas, Centro Colaborador em Análise de Situação de Saúde. Inquérito de Saúde ISACamp 2008/2009 [cited 2014 Jul 13]. Available from: http://www.fcm.unicamp.br/fcm/ccas-centro-colaborador-em-analise-de-situacao-de-saude/isacamp/2008 were analyzed in terms of health status profiles, health behaviors and use of health services in different segments of the population. This survey collected household information about people aged 10 years or older, considering three age groups: 10 to 19, 20 to 59 and 60 years and older, living in the urban area of the city of Campinas, SP, Southeastern Brazil, between 2008 and 2009. Sample size calculation totaled 1,000 individuals in each age group. A two-stage probability cluster sampling was performed: census tracts and households were drawn.⁶6 . Borim FSA, Barros MBA, Neri AL. Autoavaliação da saúde em idosos: pesquisa de base populacional no município de Campinas, São Paulo, Brasil. Cad Saude Publica. 2012;28(4):769-80. DOI:10.1590/S0102-311X2012000400016^,bb Details of the sampling process are available from: http://www.fcm.unicamp.br/fcm/sites/default/files/plano_de_amostragem.pdf

To compensate for 20.0% of refusals and empty homes, 3,900 households were selected so that at least 1,000 interviews with older adults could be obtained. Among the drawn households, there was a 6.5% loss due to the impossibility of finding a dweller or because a dweller refused to list the individuals that lived in the household. Of the 1,558 older adults identified in the drawn households, 2.4% refused to participate in the study; thus, 1,520 older adults were interviewed. Among these, in 5.8% of the cases the interviews were conducted with a caregiver or relative and were excluded from the study. Therefore, we analyzed data from 1,432 older adults with a mean age of 69.5 years (95%CI 69.1;69.9).

The participants’ data were collected by means of a questionnaire administered by trained interviewers. The questions were organized in blocks that approached topics related to morbidity, accidents and violence, emotional health, quality of life, use of services, preventive practices, use of medicines, health-related behaviors and socioeconomic characteristics. The analyzed variables concerning older adults were:

1.Global subjective health indicator. It corresponded to the answer to a scale item with five alternatives: “Generally speaking, would you say that your health is: excellent, very good, good, bad or very bad?”.

2.Physical health indicator. It was based on the older adults’ answers to the items corresponding to chronic diseases and health problems, and whether or not they caused limitations. A zero score was attributed to individuals who did not present diseases or chronic health problems; a score of one was attributed to each reported disease or problem that did not cause limitations; and a score of two was attributed to each reported disease and problem that caused limitations in daily activities. This indicator was supported by data related to the following aspects:

1. a) Chronic diseases. It corresponded to the question: “Has a doctor or health professional ever told you that you have any of the following diseases?”, with the possibility of a dichotomous response (yes or no) to: hypertension, diabetes, heart disease, cancer, rheumatism, osteoporosis, asthma/bronchitis/emphysema, tendinitis and circulation problems.

2. b) Physical signs and symptoms. The following question was asked: “Do you have any of the following health problems?”, with the possibility of a dichotomous response (yes or no) to: headache, backache, allergy, emotional problem, dizziness, insomnia and urinary problem.

3. c) Functional limitation. It was investigated by means of the question: “Does the disease or health problem (sign or symptom) limit your daily activities or not?”, for each disease or health problem reported by the older adults.

3.Mental health indicator, which consisted of the score obtained by each older adult in the Self Reporting Questionnaire 20 (SRQ-20)²²22 . Scazufca M, Menezes PR, Vallada H, Araya R. Validity of the self-reporting questionnaire-20 in epidemiological studies with older adults. Soc Psychiatry Psychiatr Epidemiol. 2009;44:247-54. DOI 10.1007/s00127-008-0425-y – an instrument with 20 dichotomous items in which each affirmative answer is equivalent to one point. Three ranges were constructed: zero to four, five to ten and ten points or more.

4.Demographic characteristics: sex and age.

5.Indicators of material life conditions: schooling and monthly per capita family income.

6.Wellbeing indicators. We considered the answers to two items of a quality of life questionnaire with 36 items the Health Survey Questionnaire – short form (SF-36):⁸8 . Ciconelli RM, Ferraz MB, Santos W, Meinão I, Quaresma MR. Tradução para a língua portuguesa e validação do questionário genérico de avaliação de qualidade de vida SF-36 (Brasil SF-36). Rev Bras Reumatol 1999;39:143-50.

1. a) Feeling of happiness (level of pleasure in daily life). It was assessed by means of the question: “Have you been feeling happy in the last four weeks?”, with the following alternatives of answer: all the time/most of the time, some of the time and a small part of the time/never.

2. b) Vitality (level of energy perceived in daily life). It was assessed by means of the question: “Have you been feeling you have a lot of energy in the last four weeks?”, with the possibilities of answer: all the time/most of the time, some of the time and a small part of the time/never.

The survey’s data were keyboarded into a database developed with the use of the EpiData software, version 3.1, and submitted to a consistency analysis. For the analyses, prevalences and their respective 95% confidence intervals were estimated. The associations between independent variables and self-rated health were analyzed by the Chi-square test, with level of significance of 5%. Poisson simple and multiple regression analyzes were also used to estimate crude and adjusted prevalence ratios. The variables that presented a level of significance lower than 20.0% (p < 0.20) were introduced into Poisson multiple regression model, in the association with the dependent variable, and the ones with p < 0.05 remained in the model. The regression model was developed in four stages. In the first stage, the demographic and socioeconomic variables were introduced; in the second, the physical health indicator was added; in the third stage, the mental health indicator was introduced; and in the fourth stage, the wellbeing indicators were added. Data analysis was carried out with the svy commands of the Stata software, version 11.0. The weights deriving from sample design were used and the existence of primary sampling units was considered.

The study was approved by the Research Ethics Committee of the Faculdade de Ciências Médicas of the Universidade Estadual de Campinas, in an addendum to Opinion 079 of 2007, referring to the project ISACamp 2008/2009 on April 27, 2010.

RESULTS

Table 1 presents the prevalence of bad/very bad self-rated health according to demographic and socioeconomic variables, physical and mental health indicators and subjective wellbeing indicators (happiness and vitality). We observed that older adults with level of schooling equal to or lower than four years and with per capita income up to three minimum salaries presented higher prevalence of bad/very bad self-rated health.

Older adults with score equal to or higher than five in the physical health indicator and who scored five or more in the SRQ-20 presented higher prevalence of negative self-rated health, with PR = 17.0 and PR = 10.1, respectively, in the categories of highest scores (Table 1). The prevalence of bad/very bad self-rated health was significantly higher among individuals who reported having a lower feeling of happiness and vitality (Table 1).

By means of the multiple regression model, we verified, in the first stage, a higher prevalence of bad/very bad self-rated health in individuals without formal schooling, in those with one to four years of schooling and whose monthly per capita family income was lower than one minimum salary. In the second stage of the analysis, those whose score was equal to or higher than five in the physical health indicator presented higher prevalence of negative self-rated health. In the third stage (Table 2), those who scored five or more in the SRQ-20 and, in the fourth stage, the categories low and intermediate level of feeling of happiness presented a higher prevalence of negative self-rated health. We observed that, even in the presence of congruence between the global self-rated health and the self-reports on diseases, signs and symptoms, disability and limitations, mental health and the feeling of happiness were important variables in the relation to self-rated health in older adults (Table 2).

DISCUSSION

A prevalence of 10.9% (95%CI 8.9;13.2) of negative self-rated health was observed among older adults, as well as an association of this subjective condition with physical and mental health indicators, with the feeling of happiness and with socioeconomic variables. These data suggest that health perception is characterized not only by favorable socioeconomic conditions and preserved physical and mental health, but also by a positive subjective wellbeing, indicated by the feeling of happiness.²⁸28 .

Age and sex did not have a significant relationship to self-rated health. Studies that investigated self-rated health in older adults in Brazil have found the same result,⁶6 .

The socioeconomic variables are important physical health correlates. Socioeconomic disadvantages influence lifestyle, use of and access to health services and social relations, and may be related to individuals’ and populations’ worse health status.²⁹29 .

Due to the insufficiency of supports such as education and the satisfaction of health, housing and transportation needs in Brazil, income plays a fundamental role in relation to the acquisition of goods and services that are necessary for social reproduction.¹⁰10 .

They found a significant association among self-rated health, income and schooling.

Chronic non-communicable diseases, which are highly prevalent in the older population, have a significant impact on the quality of life of the individuals who have them and of their relatives, with repercussions in the health sector. As the number of comorbidities of an older adult increases, his/her quality of life sharply decreases.¹²12 . Lima MG, Barros MBA, César CLG, Goldbaum M, Carandina L, Ciconelli RM.

DOI:10.1590/S1020-49892009000400005 The prevalence of chronic diseases increases as age advances, reaching more than 70.0% in people aged 70 years or older,⁴4 .

The present study found a higher prevalence ratio of negative self-rated health (“bad”) among older adults who scored five or more in the physical health indicator. The absence of an association between scores of one to four in this indicator and negative self-rated health may be related to the control of chronic diseases. This indicates the importance of reducing, diagnosing and treating common morbidities as early as possible in order to promote the quality of life of older adults. Prioritizing the control of morbidities and providing integral and continuous care are political strategies that focus on the prevention and management of chronic diseases.²³23 .

DOI:10.1016/S0140-6736(11)60135-9

The older adults’ score in the assessment of common mental disorder (characterized by somatic and depression symptoms, anxiety status, irritability, insomnia, fatigue, memory and concentration difficulties) was associated in a statistically significant way with negative self-rated health. A cross-sectional study that analyzed self-rated health in a representative sample of older adults verified that depression symptoms are the main predictors of self-rating one’s own health as bad.¹⁵15 . Millán-Calenti JC, Sánchez A, Lorenzo T, Maseda A. Depressive symptoms and other factors associated with poor self-rated health in the elderly: gender differences. Geriatr Gerontol Int. 2012;12(2):198-206. DOI:10.1111/j.1447-0594.2011.00745.x Although physical and mental health are correlated, the independent effect of each one on self-rated health is evident in the present study.

Depression generates high expenditures on health in the population aged 60 years or older, negatively affects functional capacity, is associated with somatic diseases, leads to social isolation and causes a significant decrease in the individuals’ quality of life.⁷7 . Chang-Quan H, Xue-Mei Z, Bi-Rong D, Zhen-Chan L, Ji-Rong Y, Qing-Xiu L. Health status and risk for depression among the elderly: a meta-analysis of published literature. Age Ageing. 2010;39(1):23-30. DOI:10.1093/ageing/afp187 In old age, the etiology and the psychological, behavioral and physical symptoms of depression may vary and may manifest themselves in a heterogeneous way, demanding adaptations of the forms of diagnosis and treatment.⁵5 . Batistoni SST, Neri AL, Nicolosi GT, Lopes LO, Khoury HT, Eulálio MC, et al. Sintomas depressivos e fragilidade. In: Neri AL, organizadora. Fragilidade e qualidade de vida na velhice. Campinas: Alínea; 2013. p.283-98. Due to the singularity of this disease in old age and to the findings of the present study, we emphasize the need to invest more in the prevention of depression and in the promotion of mental health as a way of contributing to improve subjective health and, consequently, older adults’ wellbeing and quality of life.

The association that was found between the feeling of happiness and self-rated health was the strongest of all the investigated relationships. A longitudinal study that investigated the determinants of self-rated health and happiness found that these variables reflect the different facets of a common basis of physical and mental wellbeing.²⁷27 .

J Epidemiol Community Health. 2005;59(8):664-9. DOI:10.1136/jech.2004.025742 Siahpush et al²⁴24 . Siahpush M, Spittal M, Singh GK.

DOI:10.4278/ajhp.061023137 (2008) assessed relationships among happiness, life satisfaction and health and observed that people with high levels of feelings of happiness had better objective and subjective health statuses.

Happiness is a hedonic state of pleasure that derives from satisfying needs and meeting goals. It is translated as the predominance of positive emotional states or as the balance between positive and negative states. It is influenced by environmental stimuli, past experiences, physiological states and intrapsychic experiences.¹⁶16 . Neri AL. Qualidade de vida na velhice e subjetividade. In: Neri AL, organizadora. Qualidade de vida na velhice: enfoque multidisciplinar. Campinas: Alínea; 2007. p.13-59. The concept of happiness integrates the concept of subjective wellbeing, which reflects the assessment that the individual himself makes of the dynamics of the relations among the conditions of the environment in which he lives, his own behavioral competence and the perceived quality of life.¹⁶16 . Neri AL. Qualidade de vida na velhice e subjetividade. In: Neri AL, organizadora. Qualidade de vida na velhice: enfoque multidisciplinar. Campinas: Alínea; 2007. p.13-59. Subjective wellbeing is connected with positive affections and, consequently, with emotional health. Older adults with higher levels of positive affections tend to use constructive coping strategies when they face the challenges that are inherent in advanced age.⁹9 . Dezutter J, Wiesmann U, Apers S, Luyckx K. Sense of coherence, depressive feelings and life satisfaction in older persons: a closer look at the role of integrity and despair. Aging Ment Health. 2013;17(7):839-43. DOI:10.1080/13607863.2013.792780

The associations that were found between physical and mental health statuses assessed by self-report and subjective appraisals of health quality suggest foci for research investment, such as the test of more detailed measures of mental health, vitality and happiness, as well as the investigation of variables that mediate the effects of health status on subjective health assessments. Other studies will be able to assess the effects of positive self-rated health among poor health statuses and on the continuity of psychosocial functioning and of the sense of happiness among older adults. Future studies will also be able to focus on prospective research to evaluate risk and protection factors for outcomes like mortality, morbidity and disability based on somatic, psychiatric and psychological risks, on subjective wellbeing and on self-rated health.

The study enables to verify independent effects on self-rated health in relation to material life conditions, physical health, mental health and wellbeing, and emphasizes the integral approach to the older adult in different dimensions. The findings show that, even in the presence of congruence between global self-rated health and self-reports on diseases, signs and symptoms, disability and limitations, mental health and the feeling of happiness are important variables in the relationship to self-rated health among older adults.
