Trajectories of social participation in old age: a systematic literature review

Abstract

Objective:

the present study aimed to identify patterns of social participation in old age and the theories used to explain them.

Method:

A systematic review was performed using the Medical Literature Analysis and Retrieval System Online (MEDLINE / PUBMED), Scientific Electronic Library Online (Scielo) and Web of Science (ISI Web of Knowledge) databases. The keywords used were: social participation, social engagement, social involvement and social activities; combined with seniors, the elderly, older adults, older people and aging. Research was performed between January and February.

Results:

thirty-one longitudinal studies on social participation among old and healthy middle-aged adults were included for analysis. In three studies social engagement levels increased, especially at the beginning of old age (up to 75 years). Twenty-one studies presented results that described the reduction of social engagement levels in old age, and five studies found that there was no change in levels of social involvement. The most used theories were: the activity theory, the social disengagement theory, the continuity theory and the theory of socioemotional selectivity.

Conclusion:

the results point to the need for reflection on what is envisioned and what is practiced in terms of policies and practices aimed at achieving successful aging. Future attempts should include not only incentives to remain active, but a description of factors that influence the social disengagement associated with poor adaptation in old age.

Keywords:
Personal Satisfaction; Social Networkings; Interpersonal Relations; Health of Elderly; Aging.

Resumo

Objetivo:

identificar trajetórias de participação social na velhice e as teorias utilizadas para explicá-las.

Método:

revisão sistemática da literatura nas bases de dados Medical Literature Analysis e Retrieval System Online (MEDLINE/PubMed), Scientific Eletronic Library Online (SciELO) e Web of Science (ISI Web of Knowledge). Os seguintes descritores foram utilizados: social participation, social engagement, social involvement e social activities; combinados com seniors, elderly, older adults, older people e aging. A pesquisa foi realizada no período entre janeiro e fevereiro de 2016.

Resultados:

trinta e um estudos longitudinais sobre participação social em idosos e adultos de meia-idade saudáveis foram incluídos para análise. Verificou-se que em três estudos, os níveis de engajamento social aumentaram, principalmente no início da velhice (até os 75 anos). Vinte e um estudos apresentaram resultados correspondentes à diminuição dos níveis de engajamento social na velhice. Cinco estudos divulgaram resultados sobre ausência de mudanças nos níveis de envolvimento social. As teorias mais utilizadas foram: a teoria da atividade, a teoria do desengajamento social, a teoria da continuidade e a teoria da seletividade socioemocional.

Conclusão:

os resultados apontam para a necessidade de reflexão sobre o que é idealizado e o que é praticado em termos de políticas e práticas para alcançar o envelhecimento bem sucedido. Os esforços futuros devem contemplar não apenas o incentivo à atividade, mas os aspectos que influenciam o desengajamento social associado à má adaptação dos idosos.

INTRODUCTION

The search for successful aging has motivated the development of several social and psychological theories in the field of gerontology11 World Health Organization. Active Ageing: a Policy Framework [Internet]. Geneva: WHO; 2001. [acesso em 16 jan 2016]. Disponível em: http://apps.who.int/iris/bitstream/10665/67215/1/WHO_NMH_NPH_02.8.pdf.,22 Achenbaum WA, Bengtson VL. Re-engaging the disengagement theory of aging: on the history and assessment of theory development in gerontology. Gerontologist. 1994;34(6):756-63.. The first conceptual models, such as the social disengagement theory, were predominantly negative and emphasized the inevitability of functional decline and dependence in old age33 Cumming E, Henry W. Growing old. New York: Basic Books; 1961.. According to this theory, successful aging involves mutual distancing between the individual and society, resulting from the decline of skills and the shortening of remaining life.

Nowadays, literature on the aging experience is replete with considerations on productivity and success, and adopts a more positive approach in relation to the experience of aging. Its main foundations are the theories of activity44 Knapp MRJ. The activity theory of aging: an examination in the English context. Gerontologist. 1977;17(6):553-9., continuity55 Atchley R. A Continuity Theory of Normal Aging. Gerontologist. 1989;29(2):183-90. and socioemotional selectivity66 Carstensen LL. Social and emotional patterns in adulthood: support for socioemotional selectivity theory. Psychol Aging. 1992;7(3):331-8..

The activity theory emerged from the observation of the positive relationship between greater levels of social involvement and satisfaction with life among the elderly44 Knapp MRJ. The activity theory of aging: an examination in the English context. Gerontologist. 1977;17(6):553-9.. According to this theory, a person is most likely to succeed in old age if they continue to be active and take on productive roles in society, replacing those that have been lost. These productive roles include community-based social activities, such as paid work, volunteering, and participation in social or religious groups44 Knapp MRJ. The activity theory of aging: an examination in the English context. Gerontologist. 1977;17(6):553-9..

The activity theory brings together an extensive amount of empirical data that corroborates practical applications such as policies to encourage health promotion through the practice of physical activities, voluntary work and, more recently, the active aging policy proposed by the World Health Organization (WHO)11 World Health Organization. Active Ageing: a Policy Framework [Internet]. Geneva: WHO; 2001. [acesso em 16 jan 2016]. Disponível em: http://apps.who.int/iris/bitstream/10665/67215/1/WHO_NMH_NPH_02.8.pdf..

The continuity theory postulated that, although individuals adapt to the aging process by adjusting the duration, mode, and distribution of activities, they tend to participate in similar activities and to continue the lifestyles adopted in adult life and middle-age. Therefore, social participation patterns remain relatively stable during one's life course55 Atchley R. A Continuity Theory of Normal Aging. Gerontologist. 1989;29(2):183-90.. Therefore, dynamism in the patterns and levels of social engagement is accepted, and includes as determinants personal motivations and preferences for activities and institutional factors.

Following the life course perspective, Carstensen66 Carstensen LL. Social and emotional patterns in adulthood: support for socioemotional selectivity theory. Psychol Aging. 1992;7(3):331-8. argues that people actively modify their social network in old age, selecting relationships and activities that are meaningful and sources of support, pleasure, and satisfaction, and setting aside relationships and activities that are burdensome, complex, stressful or the source of negative affect. This selection process is an important mechanism of adaptation in the sense of preserving emotional well-being, which is why it is known as socioemotional selectivity theory.

These important theoretical changes, accompanied by the dissemination of empirical data, have driven conceptual transitions in the field of Gerontology, challenging scholars and practitioners to deal with aging as a complex and heterogeneous process. In this context, engagement or social participation has become an important object of study. Defined as the involvement of the elderly in social activities practiced in the community, social participation is associated with a lower risk of morbidities77 Benjamins MR, Musick MA, Gold DT, George LK.

As people age, various aspects of their lives are modified, including the quantity and composition of their social networks, as well as the frequency of their participation in social activities. In addition, social behavior is influenced by personal aspects (health, gender, income, schooling), contextual (social support, physical barriers and opportunities), as well as by common events of old age that characterize socially transient moments, for example, retirement and widowhood1818 Donnelly EA, Hinterlong JE.

The objective of the present study was to identify trajectories of social participation in old age and the theories used to explain them.

METHOD

A systematic review of literature was performed, designed to identify and analyze publications that answer the questions: Do elderly persons reduce, increase or maintain levels of social participation as they grow older? Which theories are most used to explain social participation in old age?

The databases consulted were the Medical Literature Analysis and Retrieval System Online (MEDLINE/PubMed), the Scientific Electronic Library Online (SciELO) and the Web of Science (ISI Web of Knowledge). The following descriptors were used: social participation, social engagement, social involvement and social activities; combined with seniors, elderly, older adults, older people and aging. The search was carried out between January 1, 2016 and February 1, 2016.

The inclusion criteria were longitudinal studies; year of publication after 2001; publications in the Portuguese, English or Spanish languages and investigation of the social participation of healthy elderly persons and healthy middle-aged adults. Studies with caregivers and with institutionalized or hospitalized elderly persons were excluded; as were studies with other designs (such as review, cross-sectional, qualitative, and instrument validation studies). Studies that were repeated in more than one database were considered only once, according to the criteria mentioned.

The selection of articles was carried out separately by two researchers, based on the title and abstract. When there was disagreement, a third researcher was asked to decide whether to include or exclude the study. Subsequently, the researchers read the articles in full and extracted the relevant information for this study. In this stage, new exclusions were required, as demonstrated in Figure 1.

Thirty-one longitudinal studies on social participation among healthy elderly and middle-aged adults were included for analysis. Table 1 shows the relevant characteristics of the studies, such as follow-up time, sample characteristics, and the instruments and indicators used to assess social participation.

RESULTS

Most of the studies were published between 2009 and 2015 and mainly in the United States and Germany. No Brazilian study fulfilled the inclusion criteria for the analysis proposed in this study. Approximately half of the studies adopted the increase, decrease or maintenance of the incapacity to participate socially and of cognitive decline or dementia as their outcome or variable dependent. Other outcomes investigated were mortality, depression, well-being and retirement (Table 1).

Trajectories of social participation in old age

In order to answer the first research question, regarding the reduction, increase or maintenance of levels of social participation as people grow older, the results of the studies included were analyzed. It was found that in three studies levels of social engagement increased, especially in the onset of old age (up to 75 years). Twenty-one studies presented results that described a decrease in levels of social engagement as people age. Five studies reported the absence of significant changes in levels of social involvement between middle age and old age, suggesting the continuity of activities based on previous experiences accumulated during the life course of an individual (Table 2).

Use of theories

With regard to the use of theories to explain social participation in old age and its effects, we identified five theoretical reasonings that were grouped according to the best-known theories: activity, social disengagement, continuity and socioemotional selectivity. Each theory was classified based on studies that mentioned it explicitly and those that did not explicitly refer to any theory, but used their principles implicitly to explain its results. Only one study explained the use of the activity theory, while 16 studies used its principles implicitly. Studies that presented data and arguments about the positive effects of social engagement on functional, health, cognition and mortality outcomes were included in this group. Only one study implicitly used the theory of social disengagement, and none applied it explicitly. The continuity theory was explicitly mentioned in one study and implicitly addressed in two studies. The socioemotional selectivity theory was explicitly addressed in six studies and no study referred to it implicitly (Table 3). These findings relate to the second question proposed for this study.

DISCUSSION

According to the information obtained and set out in Table 1, there was significant heterogeneity among the studies regarding publication location, sample characteristics and the methods by which social participation was evaluated. The cultural and socioeconomic aspects determined by the country of origin of the study samples may have influenced the profile of the participants in terms of age, gender and living conditions. The proportion of elderly women and men differed among countries, influencing their representation in the samples of the studies. While studies on aging generally involve more women than men, the present review identified a number of studies with a higher proportion of men than women99 Avlund K, Lund R, Holstein BE, Due P.

It is known that the profile and characteristics of social participation are closely related to culture, beliefs and socially acceptable habits, as well as the opportunities and resources available in the community2424 Bukov A, Maas I, Lampert T.

The same characteristics are also influenced by gender and age. Thus, the place of origin of the elderly may imply greater or lesser participation, in spite of personal aspects related to aging. In some European and North American countries, volunteering is a widespread activity practiced by the majority of adults and elderly persons throughout their lives, while it is little practiced in Latin America and the Caribbean2525 Hank K, Erlinghagen M. Dynamics of volunteering in older Europeans. Gerontologist. 2010;50(2):170-8.. The same applies to regard to sports, religious and educational activities. This explains the variety of indicators used in literature to assess social participation. These aspects should be considered in the interpretation of the results and in the conclusions of these studies.

Important information can be obtained from the review proposed in this study. A careful reading of the work allowed us to identify the trajectories of social participation in old age, or in other words, whether people reduce or maintain levels of social engagement as they grow older. It also allowed us to identify how gerontological theories have been used to explain this phenomenon in this phase of life. These observations contribute to gerontological theory and practice in the sense of understanding the functioning and social behavior of the elderly. As a result, researchers will have greater clarity regarding the most suitable and reliable theoretical applications to support the results of their research. Professionals can use this knowledge in the field of health and social sciences to understand the mechanisms involved in the behaviors observed in practice and the implications for the health and well-being of the elderly.

The most frequently observed trajectory of social participation was the identification of diminished participation in social actions or the reduction of contact with friends and family, especially among older age groups. Several studies have identified reduced levels of social participation associated with age2222 Agahi N, Lennartsson C, Kåreholt I, Shaw BA. Trajectories of social activities from middle age to old age and late-life disability: a 36-year follow-up. Age Ageing. 2013;42(6):790-3.. This trajectory has been observed for both men and women99 Avlund K, Lund R, Holstein BE, Due P. Social relations as determinant of onset of disability in aging. Arch Gerontol Geriatr. 2004;38(1):85-99., but with different characteristics. While men tend to disengage from political and organizational activities and work, women discontinue community activities and volunteer work. This disengagement is most pronounced at age 75, and maybe influenced by common events in old age, such as widowhood, retirement, health problems, and functional decline1010 Buchman AS, Boyle PA, Wilson RS, Fleischman DA, Leurgans S, Bennett DA.

, levels of social activity are inversely proportional to the advancement of age. Lower levels of social engagement lead to more rapid motor and functional decline among the elderly. In addition, reduced social connections, the limited frequency of participation in social activities and social disengagement are predictors of cognitive decline3636 Small BJ, Dixon RA, McArdle JJ, Grimm KJ. Do Changes in Lifestyle Engagement Moderate Cognitive Decline in Normal Aging? Evidence from the Victoria Longitudinal Study. Neuropsychology. 2012;26(2):144-55.,3737 Zunzunegui M. Social networks, social integration, and social engagement determine cognitive decline in community-dwelling Spanish older adults. J Gerontol Ser B Psychol Sci Soc Sci. 2003;58(2):93-100. and dementia1212 Hughes TF, Flatt JD, Fu B, Chang CCH, Ganguli M. Engagement in social activities and progression from mild to severe cognitive impairment: the MYHAT Study. Int Psychogeriatr. 2013;25(4):587-95..

Less frequent was the observation that levels of social engagement remain stable throughout life, including in old age1818 Donnelly EA, Hinterlong JE. Changes in social participation and volunteer activity among recently widowed older adults. Gerontologist. 2010;50(2):158-69.,2020 Lancee B, Radl J. Social connectedness and the transition from work to retirement. J Gerontol Ser B Psychol Sci Soc Sci. 2012;67(4):481-90.,2121 Sabbath EL, Lubben J, Goldberg M, Zins M, Berkman LF. Social engagement across the retirement transition among "young-old" adults in the French GAZEL cohort. Eur J Ageing. 2015;12(4):311-20.,2424 Bukov A, Maas I, Lampert T. Social participation in very old age: cross-sectional and longitudinal findings from BASE: Berlin Aging Study. J Gerontol Ser B Psychol Sci Soc Sci. 2002;57(6):510-7.,3737 Zunzunegui M. Social networks, social integration, and social engagement determine cognitive decline in community-dwelling Spanish older adults. J Gerontol Ser B Psychol Sci Soc Sci. 2003;58(2):93-100.. The results of these studies point to the existence of continuity in relation to the social behaviors that are constructed and nourished throughout life and therefore influence outcomes in old age. This rationale has important practical implications. Considering that social behavior in old age is determined by previous events and experiences, the approach of these individuals to promote health and well-being through social engagement must begin in stages of life prior to old age. This implies that collective efforts must be employed to enable young people and adults to engage socially and to maintain these relationships and activities for longer, in such spaces as school, university, community and work.

According to Bukov et al.2424 Bukov A, Maas I, Lampert T. Social participation in very old age: cross-sectional and longitudinal findings from BASE: Berlin Aging Study. J Gerontol Ser B Psychol Sci Soc Sci. 2002;57(6):510-7., old age can bring a mixture of stability, reactivation and the reduction of social participation. The results of this study showed that 87% of elderly persons who performed activities in groups in the first phase of the study, continued to perform them after four years of follow-up, and 11 out of 20 socially inactive people at the beginning of the study had begun social activities by the end of the follow-up period. However, the number of participants in political and productive activities declined by half from one measurement time to another. According to the authors, when selection occurs in advanced age, it will probably be in favor of less demanding activities, and participation in more demanding activities will be interrupted. The cumulative pattern of social participation is maintained even after such selection. This argument reinforces the idea of continuity from a life course perspective.

The trajectory of increasing levels of social engagement in old age was described by three studies1717 Allyn J, Siegl E, Piliavin JA.

These results may have been influenced by the methods used to measure social participation, as depending on the social activity or instrument used, certain trajectories may be favored. For example, if the study considers participation in a remunerated activity as an indicator of social engagement, elderly populations will probably reveal a declining trend, as it is common for such individuals to retire and, therefore, to abandon such activities. However, in studies in which voluntary activity was adopted as an indicator of social participation, trajectories of increased social engagement were observed. After retirement older people are likely to enjoy more free time to engage in pleasurable and optional activities, such as volunteering1818 Donnelly EA, Hinterlong JE. Changes in social participation and volunteer activity among recently widowed older adults. Gerontologist. 2010;50(2):158-69.. The increase in social participation after retirement is a sign of selection and adaptation, to achieve or maintain favorable levels of functioning and active aging2020 Lancee B, Radl J. Social connectedness and the transition from work to retirement. J Gerontol Ser B Psychol Sci Soc Sci. 2012;67(4):481-90..

The activity theory was the concept that was most considered by the studies, albeit implicitly. In general, studies that provided results on the benefits of participation in social activities for physical and cognitive functions and those that described an increased risk of mortality associated with declining social engagement tend to justify their results by reinforcing the idea that "the more active the better", or the notion that inactivity and disuse entails a loss of skills. These precepts were contemplated by this theory and have guided important public policies for active and healthy aging11 World Health Organization. Active Ageing: a Policy Framework [Internet]. Geneva: WHO; 2001. [acesso em 16 jan 2016]. Disponível em: http://apps.who.int/iris/bitstream/10665/67215/1/WHO_NMH_NPH_02.8.pdf.. It is true that evidence of the benefits of social participation for health and well-being is robust and has been repeatedly demonstrated in several studies 1616 Huxhold O, Miche M, Schüz B.

. Empirical data have pointed out that elderly people with worse cognition are less engaged than their peers whose cognition is preserved1212 Hughes TF, Flatt JD, Fu B, Chang CCH, Ganguli M.

Social networks, social integration, and social engagement determine cognitive decline in community-dwelling Spanish older adults. J Gerontol Ser B Psychol Sci Soc Sci. 2003;58(2):93-100.. This suggests that social involvement may be an early marker of cognitive loss and that engaging in social activities provides protection against the progression of moderate cognitive impairment to a more serious condition1212 Hughes TF, Flatt JD, Fu B, Chang CCH, Ganguli M. Engagement in social activities and progression from mild to severe cognitive impairment: the MYHAT Study. Int Psychogeriatr. 2013;25(4):587-95.. People with higher levels of social engagement not only live longer but also have lower risks of health and disability issues. Other findings have stated that facilitating social activities in old age, as well as in the transition between middle age and old age, may help delay functional disability2525 Hank K, Erlinghagen M. Dynamics of volunteering in older Europeans. Gerontologist. 2010;50(2):170-8., especially in relation to mobility1010 Buchman AS, Boyle PA, Wilson RS, Fleischman DA, Leurgans S, Bennett DA.

Although most studies identified levels of the decline of social engagement in old age, the theory of social disengagement was mentioned by only one study, and even then implicitly. This contradiction may be due to criticisms of the theory, which accuse it of suggesting that such disengagement is an inevitable, reciprocal, normative and beneficial development process for both the elderly and society. This argument was not univocally confirmed by subsequent research, and although the theory is supported by real-life data, it was discredited and practically excluded from literature until the 1990s. From that time on, new theoretical efforts, such as the socioemotional selectivity theory, have contributed important conceptual advances in the field of gerontology22 Achenbaum WA, Bengtson VL. Re-engaging the disengagement theory of aging: on the history and assessment of theory development in gerontology. Gerontologist. 1994;34(6):756-63..

Today the social disengagement observed in old age is largely explained by the socioemotional selectivity theory, which proposes that, in old age, changes in the composition of the social network, family structure, work and leisure relations, and especially in social roles, influence social behavior. The social needs of old age are different from those of young adults and, therefore, social networks assume other functions among the elderly. These individuals need more social and emotional support and fewer contacts that generate recognition and social status, which is why they select a more restricted, but significant and positively affective social network1818 Donnelly EA, Hinterlong JE. Changes in social participation and volunteer activity among recently widowed older adults. Gerontologist. 2010;50(2):158-69.. Donnelly and Hinterlong18 found that widows exhibited greater levels of participation than non-widowers and widowed women were more likely to describe greater degrees of social participation than widowed men. Elderly widowers did not exhibit lower levels of participation in voluntary work than married elderly people, as was expected. The explanations for this are based on the socioemotional selectivity theory, which postulates that, in old age, there is a greater emphasis on the fulfillment of emotional and social goals.

The composition of a social network has less influence on health outcomes in middle age than in old age3333 Kim J, Yamada N, Heo J, Han A. Health benefits of serious involvement in leisure activities among older Korean adults. Int J Qual Study Health Well-being [Internet]. 2014 [acesso em 23 fev 2016]; 9:1-9.Disponível em: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4110381/pdf/QHW-9-24616.pdf

,3535 Morrow-Howell N, Putnam M, Lee YS, Greenfield JC, Inoue M, Chen H. An investigation of activity profiles of older adults. J Gerontol Ser B Psychol Sci Soc Sci. 2014;69(5):809-21.. In the former period, activities practiced with friends are more significant and more frequently described as sources of pleasure than activities practiced with family members. In contrast, Huxhold et al.1616 Huxhold O, Miche M, Schüz B. Benefits of having friends in older ages: Differential effects of informal social activities on well-being in middle-aged and older adults. J Gerontol Ser B Psychol Sci Soc Sci. 2014;69(3):366-75. found that with increasing age, elderly persons reduce their level of social activity with relatives more than they do with friends. Informal social activities with friends were associated with the reduction of negative affect, but social and mandatory activities with family members were associated with increased negative affect1616 Huxhold O, Miche M, Schüz B. Benefits of having friends in older ages: Differential effects of informal social activities on well-being in middle-aged and older adults. J Gerontol Ser B Psychol Sci Soc Sci. 2014;69(3):366-75..

Elderly persons perform fewer social activities than middle-aged adults even after controlling for health, education and partner status. These data are in line with the theory that engaging in social activities requires resources. Elderly persons are not only less healthy than middle-aged adults but also have fewer cognitive and motivational resources that enable them to engage in activities. In advanced old age, involvement with friends may be reduced due to the need for resources to maintain these relationships. On the other hand, friends who remain in the social network at more advanced ages may have been selected according to the emotional needs of the elderly persons. The nature of activities with family members may also change in old age, when the family is the main source of social support. In advanced old age, the social support of the family may become more important than the practice of leisure activities. Thus, the composition of the social network in old age is closely related to the emotional and social needs of the elderly, as well as the personal resources available66 Carstensen LL. Social and emotional patterns in adulthood: support for socioemotional selectivity theory. Psychol Aging. 1992;7(3):331-8.,2828 Hoppmann CA, Gerstorf D, Luszcz M. Spousal social activity trajectories in the Australian Longitudinal Study of Ageing in the context of cognitive, physical, and affective resources.

The socioemotional selectivity theory argues that focusing on affectively close relationships is an important method of improving emotional well-being, and is often associated with a reduction in the size of a social network. However, this strategy may inhibit the maintenance or development of some aspects of successful aging if such reductions occur at the expense of social commitment. This possibility posits the assumption that prioritizing close relationships, decreasing network size, and maintaining close network partners is universally adaptive. Probably the most adaptive factor for development in old age is a balance of social network characteristics that offer both emotional support and adequate levels of stimulation, challenge and activity. Theoretical and empirical studies on the socioemotional selection theory indicate a need for caution regarding adopting a negative view of the decline of social engagement in old age. Kim et al.3232 Kim JH, Kim M, Kim J. Social activities and health of korean elderly women by age groups. Educ Gerontol. 2013;39(9):640-54. argue that it is fundamental to distinguish voluntary disengagement from the forced social disengagement that is associated with psychic suffering.

The composition of the social network and the practice of social activities in the community configure social behavior, which influences the health and well-being of the elderly. It is a continuous, dynamic, complex and multifaceted process, which assumes diverse trajectories throughout life and in old age, according to personal and contextual factors. In this sense, some theoretical postulations are pertinent: a) social disengagement is the predominant process among aging individuals; b) this process is often associated with negative outcomes, so that being socially active is a way of preserving physical, cognitive and emotional abilities and functions, and avoiding death; and, c) contrastingly, this process may be the result of a selective, compensatory and adaptive process that promotes emotional well-being in old age.

The present study contributes to gerontological literature through a critical analysis of the main studies published on the topic in the last fifteen years. However, it is noted that the study of social participation in old age, especially in emerging countries, is little explored. Generally, this phenomenon integrates comprehensive concepts such as quality of life and well-being, which hinders its characterization and understanding. In this sense, the conclusions of this article must be interpreted carefully. Possibly, the trajectories described reflect the behavior of the elderly persons, which includes certain personal and contextual attributes that influence their participation in social activities. Thus, subsequent studies should explore these factors in order to understand the determinants of social participation in old age.

CONCLUSION

The most commonly described social participation trajectory in literature is the reduction of social networks and the reduction of participation in social activities, or in other words, of social disengagement, both in terms of its negative value as an intentional and adaptive selection process. The theories most present in the literature were the activity (implicitly) and socioemotional selectivity (explicitly) theories. These results point to the need for more careful reflection on what is idealized and what is practiced in terms of policies and practices to achieve successful aging. Future efforts should include not only incentives to remain active, but also factors that influence the social disengagement associated with the poor adaptation of the elderly.

The knowledge revealed by the present study can contribute to gerontological practice and research by helping researchers and professionals to understand the social behavior of the elderly.
